المستخلص: The present study was designed to investigate the morphological description and histological structure of the pancreas gland in Bat Pipistrellus kuhlii.A total number of (20) ,10 male and 10 female bats were used in this study after taking out the pancreas gland it was fixed with fixative solutions their the sequent steps of preparing histological slides were done after that they were stained by using routine and special stains. These stains were represented by (Heamtoxylin - Eosin, Periodic acid Schiff, Chrom alum heamtoxylin, Modified aldehyde Fuchsin and Masson’s trichrome).The morphological study showed that the pancreas gland in Kuhli's bat is represented by a compact type of pancreatic tissue it is white to yellowish color divided into three divisions head, body and tail. The pancreatic tissue lies in the abdominal cavity near the mass of intestine at the mesentery network which is connected with the coiled region of the duodenum from one side and the extended mesenteries between the dorsal part of stomach and the ventral part of spleen from the other side. The pancreas gland has only one duct that originated from the pancreatic body which is opened in the upper part of the duodenum.The pancreas gland is surrounded by loose connective tissue it extend trabeculae that divides the gland into many lobules that differs in size and shape. The pancreatic tissue is characterized into two portions, the exocrine portion and endocrine portion, the exocrine portion is represented by a compound tubule - acinar gland which consists of a large number of acini and the ductal system, each acini represented by a serous secretory unit which consists of many pyramidal cells that surround a small lumen,the apics of narrow cells are headed towards the acinar lumen while their bases are wide and based on the basement membrane. The acinar sizes are variable some acini are large others are small. The acinr cells number range from (6 to 9) cells. The ductal system which eliminate the products of secretory units to the duodenum it is initiate with centroacinar cells, these cells are connected with intercalary ducts which connected with intralobular duct, these ducts lead to the interlobular duct, which their diameter is larger than the diameter of intralobular ducts. The inter lobular ducts eliminate their secretory contents in the main duct which opened in the upper part of the duodenum.The endocrine portion is represented by clusters of cells known as islets of Langerhans which appeared as masses of cells diffused among the exocrine portion units, they're separated from each other by a thin layer of connective tissue.The islets are randomly distributed within the pancreatic tissue, it is obvious that these islets are massively concentrated in the body part of pancreas inside the lobules and around the ducts as in the pancreas head. The study also revealed that there were difference in the diameters and numbers of the islets, the mean diameters of the islets was reached (1.86) micrometer with range (1 - 2.75) micrometer whereas the mean number of islets was (1.6) islet per millimeter with rang of (1 - 3) islet.Each islet consists of three types of cells arranged as irregular clusters, they are separated from each other with blood capillary network. They were differentiated by using routine and special stains, these cells are Alpha cells they have rounded shape with oval nucleus they lies at the peripheral part of the islet. Beta cells they’re oval shaped with spherical nucleus they lies at the center of the islet, while delta cells are irregular shaped, with pale color lies between Alpha and Beta cells they’re less in number and they may appear as single cell or as small clusters and mostly lies at the peripheral part of the islet.The islet stained with faint blue in routine stains (Heamtoxylin and Eosin), and they were stained with faint blue when using special stains (Chrome alum phloxine) while the nucleus of Alpha cells stained with dark red and the Beta cells nucleus stained blue whereas Delta cells nucleus appeared in pink to pale red color. When using modified aldehyde Fuchsin the islets stained with greenish blue, alpha cells stained with orang, beta cells were blueish green and delta cells stained with green

After bringing the fish to the lab dissecting to rescet excised organs of the gills, livers, kidneys , intestines and muscles. the current study have been performed on two axis .The first axis includes the study of histopathological changes in the organs above for two species The second axis guarantees the study of the bioaccumulation of four heavy metals (lead ,copper, nickel ,cobalt) in the tissues of the liver and muscles for the purpose of finding a relationship between the two axes. The histological observations showed histopathological changes different in severity between the two specis of fish , the tissue of C.auratus seems to more be affected than the tissue of C.zillii , In the gills, the pathological changes are represented in the shape changes of secondary lamella of gills , hyperplasia and detachment of epithelial tissue . Hypertrophy and swelling in epithelial cells , hypertrophy and increase the number of chloride cells where noted . Hyperplasia cartilage in Bracket structure of gills thread which coincide with some gathering terminal oval cell nucleus often in gill, carp was seen. In the liver has represented pathological changes like congestion of liver sinusoid , fibrosis in liver tissue , degeneration and necrosis of hepatocytes and the nuclear changes represented in the dissolution of the nucleus and conglomerate chromatin material ( karyopiknosis), the appearance of some oedema and accumulation of non - living material inside and outside the hypatocytes . In kidney ,the histopathological changes included represente by epithelial cells degeneration of the renal tubules and swelling some of them leading to a narrow tubules cavity, also observed shedding the epithelial layer lining of some renal tubule, while in the glomeruli, congestion and aneurism its veins atrophy of some glomeruli was obsererved and that leads to expansion or narrowing Bomans space . In addition non - living materials in the component tissue of blood were observed, some of which are surrounded by a fibrous capsule of several layers in C.auratus kidney only. Some of non - liver materials in the cytoplasm of some of renal tubule cells were seen, while, intestinal histopathological changes were represented by degeneration of epithelial cells and necrosis of villi peaks and it was observed that the degeneration and necrosis reach in some samples to the connective tissue and often spotted muscle cells affected in the muscle layer of the intestinal wall. Also it is observedin a large numbers of mast cells infiltration in the submucosa layer of the gut C.zillii and infiltration other types of inflammatory cells in both fish species, while muscle tissue were less affected than the other organs. There were several changes represented by spongy degeneration followed by necrosis of muscle cells , and often were seen in the limping of muscle fibers and the lack of cross - planning in this muscle. These histological changes were due to water pollution of rivers under studing by various pollutants such as heavy metals that were included in thestudy and that by measuring the bioaccumulation of heavy metals in the tissues of the muscles and liver of these fish and was assured that by Histochemistry technique as it was observed that the accumulated metals in the tissues give different reflections of color by heavy element type. It was observed that when measuring bioaccumulation , the accumulation rates of some of these elements (lead and cobalt) exceeds the permitted globally border. It was observed that the accumulation of these elements vary from one organ to another and from one specis to another and from one period to another, it was found that the rates of accumulation of elements ;lead , nickel and cobalt in the muscle were higher than that in the liver and at significant difference of 0.05 level of probability, while copper showed the opposite conclusion, as its rate of accumulation in the liver was higher thane at significant differenc of 0.05 level of probability. Regarding the two periods of the study, the first period recorded higher concentration in the liver of C.zillii than the second period for copper ,Nickel and cobalt elements at significant 0.05 difference are level of probability. . The rates of concentration of heavy elements that included in the study of the water of the rivers were nearly the same to former studies, as the highest concentration recorded for lead was 602 micrograms \ liter and the less concentration was 141 micrograms \ L, while the highest concentration of copper was 77 micrograms \ liter and less concentration was 25 micrograms \ L. The highest concentration of the nickel was 392 micrograms \ liter and its less concentration was 214 micrograms him \ l. The finally highest concentration of cobalt was 173 micrograms \ liter and its less concentration was 72 micrograms \ L

المستخلص: طفيلي المقوس الكونديToxoplasma gondii هو طفيلي ابتدائي اجباري داخل الخلايا ذات النواة. له القابلية على اصابة جميع حيوانات الدم الحار ويعد هذا طفيلي ذو اهمية صحية نظرا لما له من تاثيرات مرضية. لقد اجريت عدة دراسات بينت التغيرات النسيجية التي اثرت على انسجة | Toxoplasma gondii is an a zoonotic, obligate intracellular protozoan parasite that has the capacity to infect all warm - blooded animals. Many studies done to present the histological changes of the placental and fetal tissue and organs that resulted by Toxoplasmosis infection of pregnant women and about identification of infected fetal organs, but a lot of these studies were done experimentally on laboratory animals, accordingly the present study aims to study the structural changes of the placenta and fetal tissue and to identify the fetal organs in which the organism localized that taken from aborted fetus and embryos from pregnant woman that diagnosed as infected with Toxoplasma gondii. The present study was carried out during the period December 2012 to March 2013. Eighty women who had abortion chosen randomly from that which were revised gynecology theater in hospitals in Baquba city. Their age were ranged between 16 - 45 years, (10) fetuses and (33) samples of them non - infected as control group (c) and (37) samples were infected with Toxoplasmosis (I). The study included serological examination for mothers and Macropathlogical (Gross) , histopatholgical examination and Immunohistochimcal (IHC) stain of the placenta and fetal organs. Toxoplasmosis diagnosed serologically by ELISA (Enzyme Linked immune Sorrbant Assay) test. Immuno - histological techniques are used to detect the antigen and determination of their morphological localization in fetal and placental tissue. Formalin fixed paraffin embedded tissues (placenta and specimens of organs from aborted fetus) used to determined the antigen (Toxoplasma gondii) to detect the histological changes in these tissues. The ordinary histopathlogical changes of the tissue taken from aborted fetus showed different infiltration inflammatory cell and necrosis changes in brain, liver, lung, upper and lower limbs, kidney and spleen that may be due to infection of the parasite and not all infected organs localized the parasite (Tachyzoites). The results of the study showed that (46.26%) of the randomly selected mothers among that revised to the delivery theaters and had abortion. The fetal tissue and organs of the age (8 - 24) weeks gave positive (+) result for IHC in fetuses(brain and lung) and tachyzoites was detected in that organs, but fetus tissue of the age (4 - 8) weeks was negative for that test. Macropathlogical study of the placenta showed that the weight of the infected placenta was less than the normal ranges. and calcification was not significant in the infected placenta(45.7%) compared with non infected samples (4.28%). Infarction observed high significant in infected group was 25 (35.71%) compared with control group (2.85%) (p=0.001).Necrotic foci also seen as (40%) in infected group compared with control group (14.28%), differences between the two groups was statistically significant (p=0.001). Also congestion observed high significant (p=0.001) and the congestion was seen in (45.71) in infected group and (5.71%) in control group. Histopathlogical examination for placenta showed hemorrhage, necrosis, fibroniod necrosis and degeneration in trophoblastic cell, in both first and second trimester of pregnancy. Villous vascularity observed decreased as (32.85%) in infected group compared with control group (2.85%). Fibronoid necrosis in villi showed high percentage in villi which have > 3 that observed in infected group as (72.9%) compared with control (12.12%). An increased in villous stromal fibrosis was seen in (70.27%) placenta in infected group compared with control group which was (24.24%)

المستخلص: The morphological and histological structure of digestive tract in one species of Iraqi fish that resides in Iraqi inland fresh water (Liza abu) was studied. In this study used (43) fish were in different lengths, the gut of these fish have removed to study the relationship between the length of gastrointestinal tract and the standard body length as well as for morphological and histological study. The value of relative digestive tract length (RGL) was 2.9. Intestine was the longest part of the digestive tract, the average length of intestine was (32 cm). The shape of the folds of the mucous membrane lining the walls of digestive tract showed some differences in different parts of digestive tract, in esophagus the folds were longitudinal running along the wall and it was straight, unbranched and the mean of their number was (9 - 8) folds. In the stomach the folds were longitudinal and (7 - 6) in their number, they were branched into fingerlings structures. In pyloric caeca, anterior and posterior part of intestine and rectum the folds were fingerlings in shape, unbranched and their number were (20 - 19), (27 - 26), (25 - 23), (19 - 18) respectively. Histological study was shown that the wall of the digestive tract is consist of four major coats, from the inside to the outside they were as follows : Tunica Mucosa which characterized by its clear three parts, epithelial tissue, lamina propria and muscularis mucosa. Epithelial tissue in esophagus was thick stratified squamous epithelium, in stomach was thin simple columnar epithelium and gradually increase in length in each of pyloric caeca, intestine and rectum and it was simple columnar epithelial tissue. Mucous which is secreted in esophagus is made of a large proportion of neutral and acidic mucopolysaccharide, while the mucous secreted in the cardiac stomach consist of a large proportion of neutral mucopolysaccharide and less proportion of acidic mucopolysaccharide, either, in the pyloric stomach is consist of very small proportion of both neutral and acidic mucopolysaccharide, in pyloric caeca mucous consist of a small proportion of neutral mucopolysaccharide and less proportion of acidic mucopolysaccharide, and the mucous secreted in an anterior, posterior parts of intestine and rectum consist of small proportion of acidic mucopolysaccharide and large proportion of neutral mucopolysaccharide. Lamina propria consists of connective tissue containing capillaries and lymphoid cells and it represent the basis of the folds, in the cardiac stomach it contains simple tubular glands. Muscularis mucosa characterized by the presence of muscle fibers that are not continuous, the higher thickness of this layer was in pyloric stomach. Tunica Submucosa consists of connective tissue that contains capillaries, the higher thickness of this coat was in the stomach and less thickness of this coat was in the rectum. Tunica Muscularis consists of two layers of smooth muscle fibers, the internal layer has a circular arrangement, the external layer has a longitudinal arrangement in stomach, pyloric caeca, intestine and rectum. either in esophagus tunica muscularis was arranged in inverse manner. The circular and longitudinal muscle fibers in esophagus were skeletal muscle fibers, and they were smooth and non - striated in stomach, pyloric caeca, intestine and rectum. the higher thickness of this coat was in the stomach and less thickness was in the rectum Tunica Serosa is present in all regions of digestive tract.

The statistical results also clarified that there were significant differences (P<0.05) in the mean diameters of distal convoluted tubules of the treated groups with concentration (100, 150) mg/kg for six and eight weeks of administration, while the group treated with concentration (50) mg/kg had no significant differences over the whole administration period.The study also recorded the presence of histopathological symptoms in the kidneys of treated mice with the dose (50)mg/kg represented by hemorrhage, vascular congestion, calcium casts formation inside the lumens of renal tubules, while the groups treated with (100)mg/kg of the drug showed a fibrin deposition inside renal tubular lumens, infiltration of inflammatory cells, cytoplasmic vacuolation in the epithelial cells of the renal tubules, and sloughing epithelium of renal tubules, while in the medullary region, there were epithelial cells atrophy in the renal tubules. The histological examination of mice kidneys treated with (150) mg/kg showed the appearance of hyalinization, shrinkage and complete loss of glomeruli, Pyknosis of nucleus and fibrosis around the blood vessels as well as the presence of oedema which occupied a large area of the kidney tissue
