The myeloblast is the earliest the leucocytes of the peripheral blood are of 2 main varieties, recognisable precursor of the granulocytes, normally distinguished by the presence or absence of granules: comprising about 2% of the total marrow cells. The granulocytes, blast varies considerably in size (10-18 fim in diameter), according to the appearance of nuclei, are subdivided into having a large round to oval nucleus nearly filling the cell, polymorphonuclear leucocytes and monocytes. Further, has fine nuclear chromatin and contains 2-5 well-defined pale depending upon the colour of granules, polymorphonuclear nucleoli. The thin rim of cytoplasm is deeply basophilic and leucocytes are of 3 types: neutrophils, eosinophils and devoid of granules. As the cells All forms of granulocytes are produced in the bone marrow become mature lysosomal granules appear; firstly nonand are termed,‘myeloid series’. Myeloid series include specific primary or azurophilic granules appear which are maturing stages: myeloblast (most primitive precursor), followed by specific or secondary granules that differentiate promyelocyte, myelocyte, metamyelocyte, band forms and the neutrophils, eosinophils and basophils. It possesses a round and segmented granulocytes) make up a ‘mature or postto oval nucleus, having fine nuclear chromatin which is mitotic pool’. It takes about 12 days for formation of mature slightly condensed around the nuclear membrane. Normally the bone nucleoli are present but are less prominent and fewer than marrow contains more myeloid cells than the erythroid cells those in the myeloblast. The main distinction of promyelocyte in the ratio of 2:1 to 15:1 (average 3:1), the largest proportion from myeloblast is in the cytoplasm which contains being that of metamyelocytes, band forms and segmented azurophilic (primary or non-specific) granules. The myelocyte is the stage in which Normally, the bone marrow storage compartment specific or secondary granules appear in the cytoplasm, and contains about 10-15 times the number of granulocytes found accordingly, the cell can be identified at this stage as in the peripheral blood. Following their release from the bone belonging to the neutrophilic, eosinophilic or basophilic marrow, granulocytes spend about 10 hours in the circulation myelocyte. Primary granules also persist at this stage but before they move into the tissues, where they perform their formation of new primary granules stops. The blood pool of granulocytes consists myelocyte is eccentric, round to oval, having somewhat of 2 components of about equal size—the circulating pool that coarse nuclear chromatin and no visible nucleoli. The is included in the blood count, and the marginating pool that myeloid cells up to the myelocyte stage continue to divide is not included in the blood count. The metamyelocyte stage is 10-18 compartments of granulocytes, a ‘feed-back system’ exists fim in diameter and is characterised by a clearly indented or between the circulating and tissue granulocytes on one side, horseshoe-shaped nucleus without nucleoli. The cytoplasm contains a humoral regulatory substance, ‘granulopoietin’ analogous both primary and secondary granules. Band form is juvenile granulocyte, 10the kinetics of monocytes is less well understood than 16 fim in diameter, characterised by further condensation of that of other myeloid cells. Monocytes spend about 20-40 nuclear chromatin and transformation of nuclear shape into hours in the circulation after which they leave the blood to band configuration of uniform thickness. The mature polyand contains no azurophilic granules but may have fine morphonuclear leucocytes, namely: the neutrophils, eosinogranules which are larger than those in the mature monocyte. It is very similar in appearance to myeloblasts except that it has Sites of Formation and Kinetics ground-glass cytoplasm with irregular border and may show the lymphocytes and the plasma cells are immunocompetent phagocytosis as indicated by the presence of engulfed red cells of the body. However, differentiation from are the primary lymphopoietic organs where lymphoid stem myeloblast at times may be difficult even by electron cells undergo spontaneous division independent of antigenic microscopy and, therefore, it is preferable to call the earliest stimulation. The secondary or reactive lymphoid tissue is precursor of granulocytic series as myelomonoblast. These sites actively produce cyte, about 20 fim in diameter and possesses a large indented lymphocytes from the germinal centres of lymphoid follicles nucleus containing a nucleolus. This stage is an intermediate stage their evolution into lymphocyte subpopulations and subsets. These It includes migration of immature lymphocytes to other young lymphocytes are 9-18 fim in diameter, contain round organs such as the thymus where locally-produced factors to indented nucleus with slightly stippled or coarse act on them. The mature lymphocytes are described immunologically active in cell-mediated immunity (T cells), below. After antigenic activation, B cells proliferate and lymphocytes, monocytes, eosinophils and basophils, are mature into plasma cells which secrete specific immunofound in the peripheral blood.

Some of the other common causes of involvement in myasthenia gravis is discussed in spontaneous splenic rupture are splenomegaly due to chronic Chapter 28. Sometimes Thymic hypoplasia and agenesis are acquired and congenital fragments of splenic tissue are autotransplanted within the disorders respectively in which the gland is either unusually peritoneal cavity and grow into tiny spleens there (splenosis). Acquired hypoplasia occurs as an Primary tumours of the spleen are extremely rare.

Although thymus is a lymphoepithelial organ, the term thymoma is used for the the thymus gland is a complex lymphoreticular organ lying tumour of epithelial origin. At birth, the gland weighs In about half the cases, thymoma remains asymptomatic and 10-35 gm and grows in size upto puberty, following which is accidentally discovered in X-rays. In the adult, associated conditions like myasthenia gravis or local thymus weighs 5-10 gm. The gland consists of right and left encapsulated lobes, joined together by fibrous connective tissue. Grossly, the tumour is tissue septa pass inwards from the capsule and subdivide spherical, measuring 5-10 cm in diameter with an average the lobe into large number of lobules. Sectioned surface is soft, yellowish, of the lobule shows outer cortex and inner medulla. Both cortex lobulated and may be either homogeneous or contain cysts and medulla contain two types of cells: epithelial cells and due to the presence of haemorrhage and necrosis. Microscopically, the tumour has a thick fibrous capsule Epithelial cells are similar throughout the thymus gland. The histology of lobule shows network in which thymocytes and macrophages are found. The tumour consists of neoplastic epithelial cells and variable number of non-neoplastic features of cancer. Thymoma may be of following types: malignancy may be squamous cell type (most common) Benign thymoma is more common. These include: myasthenia gravis Malignant thymoma is less common and is further of 2 (most common), hypogammaglobulinaemia, erythroid types: hypoplasia (pure red cell aplasia), peripheral T cell leukaeType 1 is cytologically benign looking but aggressive and mia/lymphoma, multiple myeloma, other autoimmune invades the mediastinal structures locally. The outer coat of arteries is the tunica from the left heart to the metabolising cells, and then back to adventitia. The blood containing oxygen, nutrients and some elastic fibres that merge with the adjacent tissues. This metabolites is routed through arteries, arterioles, capillaries, layer is rich in lymphatics and autonomic nerve fibres. These blood vessels differ from each other the layers of arterial wall receive nutrition and oxygen in their structure and function. Thus, there are structural variations Histologically, all the arteries of the body have 3 layers in the three types of arteries: in their walls: the tunica intima, the tunica media and the Large, elastic arteries such as the aorta, innominate, tunica adventitia. These layers progressively decrease common carotid, major pulmonary, and common iliac with diminution in the size of the vessels. The internal elastic lamina appears as Endothelium is a layer of flattened cells adjacent to the a single wavy line while the external elastic lamina is less flowing blood. The media primarily consists of smooth muscle endothelial cells through which certain materials pass. Structurally, they consist of the three layers as in the most important event in the initiation of thrombus formamuscular arteries but are much thinner and cannot be tion at the site. The arterioles consist of a layer of endothelial cells in the intima, one or two smooth muscle cells in the Subendothelial tissue consists of loose meshwork of media and small amount of collagen and elastic tissue connective tissue that includes myointimal cells, collagen, comprising the adventitia. The elastic laminae are virtually proteoglycans, elastin and matrix glycoproteins. Tunica media is the middle coat of the capillaries returns to the heart via post-capillary venules and arterial wall, bounded internally by internal elastic lamina thence into venules and then veins. This layer is the In the following pages, diseases of arteries are discussed thickest and consists mainly of smooth muscle cells and under 3 major headings: arteriosclerosis, arteritis (vasculitis) elastic fibres.

All 391 the three types are common in hypertension but may occur due to other causes as well. Hyaline Arteriolosclerosis Hyaline sclerosis is a common arteriolar lesion that may be seen physiologically due to aging, or may occur pathologically in benign nephrosclerosis in hypertensives and as a part of microangiopathy in diabetics; the subject is discussed again in Chapter 22. Microscopically, the thickened vessel wall shows structureless, eosinophilic, hyaline material in the intima Figure 15. This is the following morphologic entities are included under substantiated by the demonstration of immunoglobulins, arteriosclerosis: complement, fibrin and lipids in the lesions.

The vague and non-specific clinical signs of hypothyroidism and the numerous factors which influence thyroid function test results herbals interaction with antihistamines slip inn 1pack for sale, are major contributors to herbals summit quality 1pack slip inn the difficulty in diagnosing this disease lotus herbals 3 in 1 matte sunscreen purchase slip inn with a mastercard. The introduction to equine herbals slip inn 1pack low price this thesis first gives a detailed review of thyroid physiology and the general features of canine hypothyroidism. Thereafter, specific thyroid diagnostic tests currently used in dogs are discussed. Subsequently, current knowledge on influence of physiological factors, drugs and systemic diseases on thyroid homeostasis are reviewed (chapter 1). In this thesis the influence of some commonly observed clinical situations, such as the administration of medications and obesity/weight loss, on thyroid homeostasis was studied. Furthermore, thyroid function was evaluated in dogs with canine recurrent flank alopecia, a disease commonly mistaken for hypothyroidism. Chapters 2 and 3 evaluated the effects of some commonly used drugs in canine practice on thyroid function test results. The administration of medications in rats and humans can alter the synthesis, secretion, transport, or metabolism of thyroid hormones. Species differences exist in all areas of the thyroid axis, therefore it is not surprising that drugthyroid interactions will vary among species. In humans, several drugs may cause marked changes in the results of thyroid function tests, leading to difficulty in interpretation of the results, but only rarely causing clinical features of thyroid dysfunction. The effects of short-term (3 weeks) administration of oral prednisone and phenobarbital were evaluated on canine thyroid function tests (Chapter 2). Phenobarbital serum concentrations obtained in our study were slightly under usual levels aimed for in clinics. In conclusion, an immunosuppressive dosage of prednisone can markedly affect thyroid homeostasis in dogs and can lead to misinterpretation of thyroid function test results. To further assess the possible influence of common clinical situations on thyroid function test results, the effects of obesity and weight loss on canine thyroid function were assessed in chapter 4. Therefore it was important to clarify how obesity and weight loss can affect thyroid function test results in dogs. The objectives of this study were to compare thyroid function in obese dogs and in lean dogs and to explore the effects of calorie restriction and weight loss in obese dogs on thyroid hormone serum concentrations. All dogs (lean and obese) met the criteria suggested by Sauve and Paradis (2000) to confirm euthyroidism. In conclusion, obesity and energy restriction significantly altered thyroid homeostasis in dogs, but the observed changes were unlikely to affect interpretation of thyroid function test results in clinics. Clinical manifestations of hypothyroidism are nonspecific; this complicates the diagnosis of canine hypothyroidism. The most striking example is the symmetrical flank alopecia frequently observed in hypothyroidism but also a characteristic feature of a recently documented dermatological disease; i. The present study contributes to the knowledge of various aspects of canine thyroid function. The effect of weight loss was also significant on thyroid hormones, but the observed changes were clinically less relevant. Awareness of the medications and factors that alter thyroid hormone concentrations should facilitate a more accurate interpretation of thyroid function test results, hopefully avoiding the erroneous diagnosis of hypothyroidism and subsequent unwarranted treatment. De vage en niet-specifieke klinische symptomen van hypothyroidie en de vele factoren die de testresultaten kunnen beinvloeden, bemoeilijken de diagnose van deze ziekte. De inleiding van dit proefschrift geeft eerst een gedetailleerd overzicht weer van de schildklierfysiologie en de algemene kenmerken van hypothyroidie bij de hond. Daarna worden de specifieke diagnostische schildkliertesten die tegenwoordig gebruikt worden besproken. Vervolgens worden de beschikbare literatuurgegevens over beinvloeding van schildklierfunctietesten door fysiologische factoren, geneesmiddelen en systemische ziekten samengevat (hoofdstuk 1). In het onderzoek van dit proefschrift werd de invloed van veel voorkomende klinische omstandigheden, zoals het toedienen van geneesmiddelen en obesitas/gewichtsverlies op de schildklierhomeostase bestudeerd. De effecten van vaak gebruikte geneesmiddelen in de kleine huisdierenpraktijk op resultaten van schildklierfunctietesten werden onderzocht. De toediening van geneesmiddelen bij ratten en mens kan de synthese, de secretie, het transport of het metabolisme van schildklierhormonen beinvloeden. Sommige geneesmiddelen kunnen ook rechtstreeks de hypothalamus-hypophyse-schildklieras inhiberen. Daarom is het niet verwonderlijk dat de geneesmiddelschildklierinteractie interspeciesvariatie zal vertonen. Verschillende geneesmiddelen kunnen bij de mens uitgesproken veranderingen teweeg brengen in de resultaten van schildklierfunctietesten, zodat de interpretatie van deze resultaten soms moeilijk is. De effecten van kortetermijntoediening (3 weken) van orale prednisone en phenobarbital op de schildklierfunctietesten werden bestudeerd (hoofdstuk 2). Phenobarbital serumconcentraties verkregen in onze studie lagen echter iets onder de therapeutische plasmaspiegels. Men kan besluiten dat de toediening van een immunosuppressieve prednisonedosis een uitgesproken effect heeft op de schildklierhomeostase en kan leiden tot vals-positieve diagnoses van hypothyroidie. Ketoprofen toediening had geen significante invloed op de schildklierfunctietesten. Om verder de mogelijke invloed van vaak voorkomende klinische omstandigheden op de schildklierfunctietesten na the gaan, werd de invloed van obesitas en gewichtsverlies geevalueerd in hoofdstuk 4. Bij de hond is obesitas de meest voorkomende nutritionele aandoening en gewichtsverlies is de hoeksteen van de behandeling. Daarom is het belangrijk na the gaan hoe obesitas en gewichtsverlies schildklierfunctietesten kunnen beinvloeden bij de hond. De doelstellingen van deze studies waren eerst de schildklierfunctie the vergelijken tussen honden met obesitas en slanke honden. Verder werden de effecten van calorierestrictie en gewichtsverlies op schildklierhormoonconcentraties nagegaan bij honden met obesitas. Alle honden (slank en met obesitas) voldeden aan de criteria gesuggereerd door Sauve en Paradis om euthyroidie the bevestigen. Er kan besloten worden dat obesitas en gewichtsverlies tot een significante verandering van de schildklierhomeostase bij de hond leiden, maar het is weinig waarschijnlijk dat deze veranderingen relevant zijn voor de interpretatie van schildklierfunctietesten in de kliniek. Klinische tekens van hypothyroidie zijn niet specifiek; dit bemoeilijkt de diagnose van hypothyroidie bij de hond. Het meest opvallend voorbeeld is de symmetrische flankalopecie, frequent gezien bij hypothyroidie maar ook een typisch kenmerk van een recent erkende dermatologische aandoening, namelijk recidiverende flankalopecie bij de hond. De huidige studie draagt bij tot de kennis van verscheidene aspekten van de schildklierfunctie bij de hond. Het effect van gewichtsverlies op schildklierhormoonconcentraties was ook significant, maar deze veranderingen zijn klinisch weinig relevant. De oorzaak van caniene recidiverende flank alopecie blijft onbekend maar in deze studie kon schildklierdysfunctie als voornaamste oorzaak van deze ziekte worden uitgesloten. Door rekening the houden met de invloed van bepaalde geneesmiddelen en omstandigheden op de schildklierfunctietesten, worden er hopelijk minder valspositieve diagnose van hypothyroidie gesteld en bijgevolg ook minder onnodige behandelingen uitgevoerd. Het is niet mogelijk met enkele woorden the vertellen hoe sommigen voor mij zo belangrijk waren en dit niet alleen voor de ondersteuning op professioneel vlak maar ook langs het werk om zo de nodige innerlijke rust the vinden die absoluut vereist is om professioneel goed the kunnen functioneren. Ik hoop tevens dat dit proefschrift slechts een begin is voor nog vele verdere studies. Als promotor van dit proefschrift heeft hij steeds het volste vertrouwen in dit werk gesteld en mij aangemoedigd wanneer het nodig was. Zijn steun voor het realiseren van mijn onderzoek alsook voor het ontwikkelen van mijn klinische activiteiten in de Vakgroep Geneeskunde en Klinische Biologie van de Kleine Huisdieren zijn zeer waardevol geweest gedurende de laatste 2 jaren. Extra dank omdat hij mij tevens kon overtuigen dat dit doctoraat voor mij haalbaar was. Ook heb ik steeds, via hem, ook van de vakgroep Medische Beeldvorming van de Huisdieren op de nodige technische hulp kunnen rekenen. Manon Paradis die de interesse in mij wekte voor wetenschappelijk onderzoek en mij begeleidde tijdens mijn eerste klinische studies. Mijn nieuwsgierigheid voor de schildklierproblematiek heb ik van deze fantastische vrouw geerfd. Het was zeker een zeer mooie bijdrage tot 2 van de studies in dit proefschrift, en hopelijk de basis voor vele andere studies en talrijke publicaties.
Namely herbs life is feudal purchase slip inn now, low intrathyroidal iodine content presents an additional risk for deleterious effects of iodine herbals essences generic 1pack slip inn fast delivery. Prevalence of thyroid autonomy is higher in iodine-deficient or previously-iodine-deficient areas herbals for hair loss buy generic slip inn 1pack online. It seems herbs pool purchase genuine slip inn line, that in iodine-deficient areas, hyperplasia of the thyroid gland occurs already in youth. In hyperplastic glands, the rate of mutations is increased, resulting in thyroid autonomy or in dedifferentiated cold thyroid nodules. Often it takes many years, before hyperthyroidism aggravates from subclinical to overt. It has been reported that hyperthyroidism develops when the product between the weight of autonomous tissue, the efficiency per gram of tissue, and iodide supply goes above a treshold. Hence it follows that an increase in iodine intake represents a risk factor for aggravation of hyperthyroidism in these patients. Iodine excess often deteriorates subclinical or overt hyperthyroidism to the severe stage. Low intrathyroidal iodine concentration, as observed in patients with toxic adenomas when compared with healthy thyroids, presents an additional risk for deleterious effects of iodine load. Hyperthyroidism Patients with thyroid autonomy may be euthyroid, subclinical or overt hyperthyroid. In the hyperthyroidism due to thyroid autonomy, the patients are often oligosymptomatic. They may have an enlarged thyroid gland, palpitations, arrythmias, restlessness or weight loss. Because hyperthyroidism develops slowly, the patients get used to the increasingly higher levels of thyroid hormones, probably by down-regulation of thyroid receptors. In that type of hyperthyroidism, the laboratory tests usually show mild hyperthyroidism but rarely severely increased thyroid hormones. This is probably due to the low iodine content in the thyroid cells in autonomous tissue, while cells in the healthy thyroid gland secrete more fT4 than fT3. However, even in subjects with healthy thyroid gland, hyperthyroidism may developed after iodine load. How much iodine is too much for the development of iodine-induced hyperthyroidismfi This depends on the previous iodine supply, on the source and amount of iodine intake and on previous thyroid pathology. Autoregulation is a mechanism that enables a normal thyroid function in spite of iodine excess. Autoregulation decreases the intrathyroidal iodine content after an initial increase following the iodine load. The main sources of iodine excess are amiodarone, contrast media in radiology, topical antiseptics and iodine containing vitamins. Among them, the most important are amiodarone because of its high iodine content, radiology contrast agents because of their broad usage, the same holds true for iodine containing vitamins. The most important iodine source is amiodarone, a fat-soluble agent with a prolonged half-life of 100 days. One 200 milligram tablet contains 75 milligrams of iodide, about 10% is deiodized daily. Water soluble contrast media contain around 400 milligrams of iodide per mL, but only a small amount as a free iodide, which is rapidly cleared from the plasma through kidneys. During recent years, multivitamins which, beside other vitamins, usually also contain 100 to 200 micrograms of iodine, have become increasingly popular in different age groups, especially in older people and in pregnant women. This way, they can increase the iodine intake above recommended or even above safe values. Besides large amounts of iodine, amiodarone influences the thyroid status also by inhibition of deiodinase D1, which decreases serum concentrations of fT3, by inhibiting transcription of T3 receptor and by a cytotoxic action on thyroid follicular cells. The latter effect can lead to abnormal thyroid function even in normal, healthy thyroid glands and not only in individuals 22 Gaberscek S. Hyperthyroidism with preexisting thyroid disease, who are usually more susceptible to deleterious effects of amiodarone. The incidence of thyroid function abnormalities under the influence of amiodarone lies between 14 and 18%. In areas with adequate iodine intake, amiodarone provokes hypothyroidism more often than hyperthyroidism. This is due to the large amount of iodine, the higher incidence of thyroid autoimmunity and due to a sort of resistance of thyroids, probably caused by the changed autoregulatory mechanism. In iodine-deficient areas, hyperthyroidism is more frequent than hypothyroidism because of higher incidence of autonomy in goiters. The patients with iodine-induced hyperthyroidism are often older, suffering also from other diseases, especially cardiovascular. Iodine-induced hyperthyroidism is a very serious condition to treat and it often takes several months to restore the normal thyroid function. This is due to a faster synthesis of T4 in the thyroid gland due to a very high iodine supply. At the initial stage of the development of iodine-induced hyperthyroidism, we can observe increased fT4 level and only slightly increased fT3 level, which later follows fT4 level more adequatly, when hyperthyroidism begins to increase deiodase D1 activity. Thyroiditis causes follicular disruption and release of thyroid hormones, stored in the thyroid cells, into the blood, resulting in hyperthyoidism. Patients suffer from fever, severe pain that extends to the ear, and they may have symptoms of hyperthyroidism. This is probably due to the predominant release of fT4 from the intrathyroid stores. Hyperthyroidism is often mild and transient, followed by euthyroidism and hypothyroidism, which can be transient or permanent in 30%. Some patients have only several symptoms, while others develop a whole spectrum of symptoms. Most frequent clinical manifestations of hyperthyroidism are nervousness, fatigue, weakness, heat intolerance, tremor, hyperactivity, palpitations, weight loss, rarely weight gain, hyperactivity, tachycardia or atrial fibrillation, systolic hypertension, warm and moist skin. In continuation, clinically most relevant symptoms and signs of hyperthyroidism will be listed. Thyroid hormones decrease the systemic vascular resistance and the diastolic blood pressure, and increase the cardiac output, the nitric oxide, the systolic blood pressure, the heart rate, the cardiac contractility, the cardiac mass and the blood volume. Patients may have anemia due to ineffective erytropoiesis, iron deficiency, vitamin B12 deficiency and folate deficiency. They have difficulty arising from a sitting or supine position and raising arms over the head. The degree of muscular weakness is more connected with the duration of hyperthyroidism than with the biochemical severity. Meta analysis showed a 41% increase in all-cause mortality in case of subclinical hyperthyroidism, the risk seems to be dependent on the age at diagnosis, with a significant increase beginning at the age of 60 years, especially in men (6). These data indicate that even a very mild hyperthyroidism should be treated, even in asymptomatic older patients. Besides clinical data, diagnostics of hyperthyroidism include also laboratoy findings, ultrasound of the thyroid gland, and if necessary, also scintigraphy of the thyroid gland. For the determination of thyroid status, free thyroid hormones should be measured. Approximately 1% of patients has a normal fT4 and an increased fT3 level (tri-iodothyronine toxicocis). If one only relied on the determined fT4 levels, these patients would be misdiagnosed. In such a case, the mutation of fi-nuclear receptor causes a resistance to thyroid hormone. If pituitary is more affected by mutation than the periphery, the patients have symptoms and signs of hyperthyroidism. The patients with iodine-induced hyperthyroidism have significantly higher fT4 than fT3 values. Colour flow Doppler sonography seems not to be useful for the distinction between cold and hot nodules.
For decontaminating equipment planetary herbals quality 1pack slip inn with mastercard, a contact time of 30 minutes before normal cleaning is required herbals aarogya order 1pack slip inn fast delivery. This is corrosive to krishna herbals order slip inn from india most metals and injurious to herbals product models purchase 1pack slip inn mastercard most fabrics, so rinse thoroughly and oil metal surfaces after completion. Agents are rendered completely harmless by sterilization with dry heat for 2 hours at 160°C. If autoclaving with steam at 121 degrees centigrade and 1 atmosphere of overpressure (15 pounds per square inch), the time may be reduced to 20 minutes, depending on volume. Solar ultraviolet radiation has a disinfectant effect, often in combination with drying. This is effective in certain environmental conditions but is hard to standardize for practical usage for decontamination purposes. The health hazards of environmental contamination by biological agents differ from those posed by persistent or volatile chemical agents. Aerosolized particles in the 1-5 µm size range will remain suspended by brownian motion and can disseminate widely. Possible exceptions include residua near the 121 dissemination line or in the immediate area surrounding point-source munitions. Simulant studies at Dugway Proving Ground suggest that secondary reaerosolization would be difficult, but may pose a human health hazard. If grossly contaminated terrain, streets, or roads must be passed, the use of dust-binding spray to minimize reaerosolization may be considered. If it is necessary to decontaminate these surfaces, chlorinecalcium or lye may be used. Otherwise, rely on the natural processes that, especially outdoors, lead to the decontamination of agent by drying and solar ultraviolet radiation. Rooms in fixed spaces are best decontaminated with aerosolized gases or liquids. This is usually combined with surface disinfectants to ensure complete decontamination. It is liberated from preganglionic and postganglionic endings of parasympathetic fibers and from preganglionic fibers of the sympathetic as a result of nerve injuries, whereupon it acts as a transmitter on the effector organ; it is hydrolyzed into choline and acetic acid by acetylcholinesterase before a second impulse may be transmitted. Active immunization The act of artificially stimulating the body to develop antibodies against infectious disease by the administration of vaccines or toxoids. Anaphylaxis the term is commonly used to denote the immediate, transient kind of immunologic (allergic) reaction characterized by contraction of smooth muscle and dilation of capillaries due to release of pharmacologically active substances (histamine, bradykinin, serotonin, and slow-reacting substance), classically initiated by the combination of antigen (allergen) with mast cell-fixed, cytophilic antibody (chiefly IgE). Antitoxin An antibody formed in response to and capable of neutralizing a biological poison; an animal serum containing antitoxins. Arthralgia Severe pain in a joint, especially one not inflammatory in character. Ataxia An inability to coordinate muscle activity during voluntary movement, so that smooth movements occur. Most often due to disorders of the cerebellum or the posterior columns of the spinal cord; may involve the limbs, head, or trunk. Atelectasis Absence of gas from a part or the whole of the lungs, due to failure of expansion or resorption of gas from the alveoli. Atropine An anticholinergic, with diverse effects (tachycardia, mydriasis, cycloplegia, constipation, urinary retention) attributable to reversible competitive blockade of acetylcholine at muscarinic type cholinergic receptors; used in the treatment of poisoning with organophosphate insecticides or nerve gases. Bilirubin A red bile pigment formed from hemoglobin during normal and abnormal destruction of erythrocytes. Blood agar A mixture of blood and nutrient agar used for the cultivation of many medically important microorganisms. A-1 Bronchiolitis Inflammation of the bronchioles, often associated with bronchopneumonia. Brucella A genus of encapsulated, nonmotile bacteria (family Brucellaceae) containing short, rodshaped to coccoid, Gram-negative cells. These organisms are parasitic, invading all animal tissues and causing infection of the genital organs, the mammary gland, and the respiratory and intestinal tracts, and are pathogenic for man and various species of domestic animals. Bubo Inflammatory swelling of one or more lymph nodes, usually in the groin; the confluent mass of nodes usually suppurates and drains pus. Carbuncle Deep-seated pyogenic infection of the skin and subcutaneous tissues, usually arising in several contiguous hair follicles, with formation of connecting sinuses; often preceded or accompanied by fever, malaise, and prostration. Cholinergic Relating to nerve cells or fibers that employ acetylcholine as their neurotransmitter. Coccobacillus A short, thick bacterial rod of the shape of an oval or slightly elongated coccus. Cyanosis A dark bluish or purplish coloration of the skin and mucous membrane due to deficient oxygenation of the blood, evident when reduced hemoglobin in the blood exceeds 5 g per 100 ml. Diathesis The constitutional or inborn state disposing to a disease, group of diseases, or metabolic or structural anomaly. Distal Situated away from the center of the body, or from the point of origin; specifically applied to the extremity or distant part of a limb or organ. Dysarthria A disturbance of speech and language due to emotional stress, to brain injury, or to paralysis, incoordination, or spasticity of the muscles used for speaking. A-2 Dyspnea Shortness of breath, a subjective difficulty or distress in breathing, usually associated with disease of the heart or lungs; occurs normally during intense physical exertion or at high altitude. Ecchymosis A purplish patch caused by extravasation of blood into the skin, differing from petechiae only in size (larger than 3 mm diameter). Another antibody 2+ labeled with a ruthenium tris-bipyridyl compound (Ru(bpy)3) is introduced. A magnet is used to pull the beads to an electrode which is used to excite the ruthenium compound which then emits light. Eczema Generic term for inflammatory conditions of the skin, particularly with vesiculation in the acute stage, typically erythematous, edematous, papular, and crusting; followed often by lichenification and scaling and occasionally by duskiness of the erythema and, infrequently, hyperpigmentation; often accompanied by sensations of itching and burning. Enanthem, enanthema A mucous membrane eruption, especially one occurring in connection with one of the exanthemas. Endotracheal intubation Passage of a tube through the nose or mouth into the trachea for maintenance of the airway during anesthesia or for maintenance of an imperiled airway. Enzyme Linked Immunosorbent Assay A method used in microbiology to detect microorganisms such as bacteria or viruses. It works by chemically linking an enzyme to an antibody that recognizes and adheres to the desired microorganism. Any unbound antibodyenzyme complex is removed and chemical which is converted by the enzyme into a fluorescent compound is applied and allowed to react. The fluorescence is then detected to reveal the presence or absence of the microorganism. Denoting a temporal pattern of disease occurrence in an animal population in which the disease occurs with a frequency clearly in excess of the expected frequency in that population during a given time interval. An outbreak (epidemic) of disease in an animal population; often with the implication that it may also affect human populations. A-3 Erythema multiforme An acute eruption of macules, papules, or subdermal vesicles presenting a multiform appearance, the characteristic lesion being the target or iris lesion over the dorsal aspect of the hands and forearms; its origin may be allergic, seasonal, or from drug sensitivity, and the eruption, although usually self-limited. Exanthema A skin eruption occurring as a symptom of an acute viral or coccal disease, as in scarlet fever or measles. Fasciculation Involuntary contractions, or twitchings, of groups (fasciculi) of muscle fibers, a coarser form of muscular contraction than fibrillation. Fomite Objects, such as clothing, towels, and utensils that possibly harbor a disease agent and are capable of transmitting it. Fluorescent antibody A method used in microbiology to detect microorganisms usually bacteria. An antibody with an attached fluorescent molecule is applied to a slide containing the bacteria and washed to remove unbound antibody. Fulminant hepatitis Severe, rapidly progressive loss of hepatic function due to viral infection or other cause of inflammatory destruction of liver tissue. Generalized vaccinia Secondary lesions of the skin following vaccination which may occur in subjects with previously healthy skin but are more common in the case of traumatized skin, especially in the case of eczema (eczema vaccinatum). In the latter instance, generalized vaccinia may result from mere contact with a vaccinated person. Secondary vaccinial lesions may also occur following transfer of virus from the vaccination to another site by means of the fingers (autoinnoculation). Glanders A chronic debilitating disease of horses and other equids, as well as some members of the cat family, caused by Pseudomonas mallei; it is transmissible to humans.
