Цель - изучение влияния сочетанной трансплантации мультипотентных мезенхимальных стромальных (ММСК) и гемопоэтических стволовых клеток (ГСК), выделенных из плаценты, на регенерацию белой и красной пульпы селезенки в физиологических условиях и в условиях воздействия ионизующего излучения. Методика. Эксперименты выполнены белых лабораторных беспородных мышах-самцах. Облучение животных проводилось на гамма-терапевтической установке типа АГАТ-С с радионуклидным источником Co-60 типа ГИК-8-4, поглощенная доза составила 4,0 Гр, мощность поглощенной дозы 20 сГр/мин. Животным опытной группы внутривенно вводились аллогенные ММСК и ГСК соответственно в дозе 6 млн клеток/кг и 330 тыс. клеток/кг, суспендированные в 0,2 мл 0,9% раствора NaCl. Выделение гемопоэтических стволовых клеток осуществлялось методом прямой иммуномагнитной сепарации. Проводили морфометрию лимфоидных фолликулов селезенки (средняя площадь, средняя площадь В-зоны, средняя площадь герминативного центра, средняя площадь T-зоны), а также определялось среднее расстояние между центрами фолликулов и средняя клеточность красной пульпы. Результаты. Показано, что после воздействия ионизирующего излучения на фоне сочетанной трансплантации ММСК и ГСК происходит увеличение размеров лимфоидного фолликула за счет площади B-зоны фолликула, площади герминативного центра фолликула, восстановление содержания лимфобластов, пролимфоцитов и лимфоцитов до значений нормы. На фоне трансплантации ММСК и ГСК в условиях лучевой нагрузки установлено увеличение плотности клеток в красной пульпе селезенки и, как следствие, увеличение расстояния между центрами лимфоидных фолликулов. Увеличение плотности клеток в красной пульпе происходит как за счет увеличения содержания эритроидных клеток, так и за счет увеличения гранулоцитов. Заключение. Проведенные исследования свидетельствуют об эффективности сочетанной трансплантации ММСК и ГСК в отношении основных морфометрических показателей селезенки после воздействия ионизирующего излучения. The purpose of this work was to study the effect of combined transplantation of multipotent mesenchymal stromal (MSCS) and hematopoietic stem cells (HSCs) isolated from the placenta, on the regeneration of white and red pulp of the spleen under physiological conditions and in conditions of exposure to ionizing radiation. Methods. The experiments were performed with laboratory mice-males. We studied the influence of ionizing radiation dose of 4.0 Gy. Animals of the experimental group were intravenously infused into MMSC and GSK respectively at a dose of 6 million cells/kg and 330 thousand cells/kg, suspended in 0.2 ml of 0.9% NaCl solution. The selection of hematopoietic stem cells was carried out using the direct technique of immune magnetic separation. Were studied the following morphometric parameters of the spleen: the average area of lymphoid follicles, the average area of zone of lymphoid follicles, average size of germinal center of lymphoid follicles, average size T-zones of lymphoid follicles, the average distance between the centers of the follicles, the average cellularity of the red pulp. Results. As a result, of research obtained that after exposure to ionizing radiation on the background of combined transplantation of HSC and MSCS there is an increase in size of lymphoid follicle at the expense of area B-zone of the follicle, the area germinative center of the follicle, restoring the content of lymphoblasts and lymphoblasts and lymphocytes to normal values. On the background of transplantation MMSC and GSK in terms of radiation exposure changes and the red pulp of the spleen. The increase in the density of cells in the red pulp of the spleen and, as a consequence, of the increase of the distance between the centers of lymphoid follicles. The increase in the density of cells in the red pulp occurs due to the increase in the content of erythroid cells and by increasing granulocytes. Key words: ionizing radiation, multipotent mesenchymal stromal cells, hematopoietic stem cells, spleen, regeneration. Conclusion. Studies have shown the effectiveness of combined transplantation MSC and GSK in respect of the main morphometric parameters of the spleen after exposure to ionizing radiation.

AbstractThe present histochemical study was carried out to analyze the distribution and topography of acetylcholinepositive nerve fibers in the thymus and bursa of Fabricius of quails. The AChE-positive nerve fibers were demonstrated by direct thiocholine histochemical method. Nerve fibers present in the thymuses form periarterial nerve plexuses located mostly in the interlobular septa and on the cortico-medullary junction. Vessels-independent nerve fibers occur also in the parenchyma of thymic medulla, but rarely in parenchyma of the cortex. Within the connective tissue between the bursa of Fabricius and the wall of proctodeum we observed conspicuous AChE-positive ganglia, often in close relationship to greater arteries. Within the wall of bursa of Fabricius, AChE-positive nerve fibers create nerve plexuses around arteries. We observed a close relationship between lymphoid follicules in bursal submucosa and mucosa and AChE-positive nerve fibers. Nerve fibers create a ring around lymphoid follicles, but do not penetrate into the germinal center of the follicle. Arteries inside quail thymuses and bursae of Fabricius contain rich AChE-positive nerve plexuses, when compared to the veins, which have a very poor presence of AChE-positive nerves. According to lesser presence and decreased density of AChE-positive nerve fibers in older animals, we described age-dependent changes in both quail primary lymphoid organs.

Abstract Splenic hamartoma is a rare, benign vascular proliferation that is often found incidentally while working up other complaints or at autopsy. Women more commonly present with symptoms related to mass effect than men. Histologic findings consist of unorganized vascular channels of varying width, with intervening red pulp–like disorganized stroma with or without lymphoid follicles. The endothelial cells are similar to those of normal splenic sinuses. Although rendering a diagnosis can be difficult, endothelial cells that are positive for CD8 are a key feature that differentiate hamartoma from other vascular lesions of the spleen. Clinical, radiologic, and histologic correlation is essential to ensure this benign lesion is not mistaken for malignancy.

Fungicides are usually used in agriculture and often find their way in poultry feed. Therefore, a study was undertaken to study the in vivo effect of one such fungicide (ziram) induced intoxication on pathomorphology of broiler chicken. After 2 weeks of age the birds were given fungicide (Ziram) in feed as a single oral dose of 100 mg/kg body weight. Out of 10 birds, 3 died due to ziram intoxication (30% mortality rate). Birds that died rapidly showed pronounced neurological signs like convulsions. The carcasses of ziram intoxicated birds appeared dehydrated and their mucous membrane was pale in colour. Marked vascular congestion was observed in brain on gross examination. The livers showed congestion and haemorrhages with necrotic foci. Kidneys and lungs had ecchymotic haemorrhages and heart revealed gelatinization of pericardium, distention and pericarditis. Atrophy of bursa of Fabricius and thymus; hypertrophy of thyroid was found. Histopathological examination revealed neuronal degeneration and necrosis associated with mild gliosis in brain. Lungs, pericardium and epicardium had severe congestion and there was degeneration with separation of myofibers. Glomeruli were congested and frequently revealed hypercellularity. There were sinusoidal congestion and varying degrees of hepatocellular degeneration. Bursa revealed mild depletion of lymphoid cells in few lobules while as thymus showed hypoplasia with depletion of lymphocytes. Thyroid had mild mononuclear cell infiltration and caecum showed marked necrosis and denudation of the mucosa. In conclusion, the depletion of lymphoid tissue from lymphoid organs was suggestive of immunosuppressive and immunomodulatory effects of ziram toxicity in broiler chicken.

Abstract 1. Critical size analysis of the lymphoid cell populations of the developing chick bursa of Fabricius and thymus indicates that characteristic shifts in cell size distribution, modal cell volume and mean cell volume occur during morphogenesis of these organs. 2. Comparison of bursa and thymus shows that while there are clear differences between the lymphoid cells of these two structures, the pattern of morphogenetic change is similar. 3. 19-nortestosterone injected in low doses can partially inhibit bursal development without affecting thymus morphogenesis. Depending on the age of the embryo at time of injection, however, doses sufficient to produce complete bursal inhibition may also retard thymic morphogenesis. 4. The size differences found between bursal and thymic lymphocytes in the chicken parallel the size differences found between lymph node and thymic lymphocytes in the mouse.

Development of Ig-synthesizing cells in the bursa of chick embryo was studied by immunohistochemical staining method as well as by in vitro incorporation of leucine-3H into Ig. Ig-synthesizing cells are first detected in the bursa of a 14 day old chick embryo and increase with the maturation of the embryo. Acrylamide gel analysis of leucine-3H-labeled Ig shows that synthesis of nonsecretory IgM-H0 precedes that of secretory IgM-H, reflecting an ontogenetic sequence of development of lymphoid cells synthesizing IgM. Since IgM-H0 is not secreted, we further studied biochemical differences between two heavy chains. The difference is attributable to lack of galactose attachment to H0 chains. It is proposed that during differentiation of lymphoid cells synthesizing and secreting Ig, attachment of galactose may play an obligatory role in the development of cellular capacity for Ig secretion.

Five groups of genetically susceptible chickens were inoculated at hatching with lymphoid leukosis virus; four of these were given infectious bursal viruses of varying virulence at 14 days of age and one group was not inoculated (control). All chickens in the control group developed evidence of lymphoid leukosis by 180 days. Two groups given relatively virulent bursal disease viruses, which destroyed bursal lymphoid cells, did not develop lymphoid leukosis. Treatment with avirulent vaccines had no visible effect on bursal morphology and did not significantly alter the incidence of lymphoid leukosis in two other groups, although the lime of development was delayed. Results of our study show that viral-induced destruction of the bursa of Fabricius eliminates the development of lymphoid leukosis but that infection without bursal destruction has little effect on lymphoid leukosis.

A study was conducted to determine the pathological toxic effect of selenium (Sodium selenite). A total number 120 one day old White Leghorn (WLH) healthy broiler birds were randomly divided into A, B and C groups. Each group contain 40 birds daily administration of sodium selenite @ 30ppm and @ 15 ppm in group A and B, respectively and group C was given plain drinking water daily for 42 days and kept as control. Macroscopically and microscopically revealed varying degrees of congestion and haemorrhages in lungs, liver, kidneys, heart and intestine in selenium treated birds. The bursa of Fabricius showed depletion of lymphoid cells between the interfollicular spaces. A significant (P less than 0.05) decrease in the haemoglobin and packed cell volume was noticed in both the selenium fed groups but the total erythrocyte count remain unchanged. Biochemical parameter revealed slight decline in their activity of serum ALT and AST and increased level of BUN and creatinine in group A and B as compared to group C, suggesting some degree of renal dysfunctioning.
