The purpose of this study was to determine the morphological and morphometric characteristics of the interdigital gland in Kivircik sheep. The interdigital glands in the forefeet and hind feet of the 16 male Kivircik sheep were examined in terms of morphometric and morphological characteristics. Four lengths (length of duct and corpus, diameter of duct and corpus) and 2 angles (angle of internal and external flexure) were measured in the interdigital glands located between 2 digits after dissection. The interdigital gland contained orifice, excretory duct, flexure, and corpus sections. Lengths and widths of corpus and excretory ducts of the interdigital gland were 2.19, 2.68, 0.47, and 0.20 cm, respectively. The diameter of the excretory duct, external angle, diameter of corpus, and diameter of excretory duct in the right interdigital glands of the Kivircik sheep were higher than those of the left interdigital glands, a statistically significant difference. The apocrine gland secretion was PAS-and AB-positive.

Pancreas in the vertebrates is subdivided into two parts: One of them is exocrine part where digestive enzymes are released and the other one is endocrine part where regulatory hormones are released into blood circulation 1 . The endocrine part, formed by the islets of Langerhans, is multihormonal unit composed of at least four types of cells; the insulin (B cells), the glucagon (A cells), the somatostatin (D cells), and the pancreatic polypeptide (PP cells) 2 .Insulin is synthesized in the B cells of the pancreatic islets and regulates the blood glucose levels. Glucagon

The aim of the present study was to determine the histological structure and histochemical properties of the pancreatic ducts in the goose Anser anser. Pancreatic ducts of 6 male and 6 female geese were examined. Crossman's triple stain and Masson's trichrome stain were used for histological examination, and periodic acid-Schiff, alcian blue, periodic acid-Schiff/alcian blue, and aldehyde fuchsin/alcian blue stainings were performed for histochemical examination. Dorsal and ventral pancreatic ducts were found that transfer pancreatic secretion into the duodenum of the goose, and these channels were found to have a histologically similar structure. No differences were detected between male and female geese. Duct wall was observed to consist of mucosa, muscle, and adventitial layers. In addition to dark principal, light and basal cells were observed in a simple columnar epithelium layer lining the duct. Glands, including centroacinar cells, were also detected in all layers of duct. Furthermore, lymphoid follicles were observed in the connective tissue of the mucosa. Sulfated and carboxylated mucosubstance-secreting cells were found in the duct as well as neutral, acidic, and mixed mucosubstance-secreting cells. We conclude that the results of our study may contribute to future studies.

Peritoneal adhesions are seen frequently after abdominal surgery and can cause serious complications. We aimed to evaluate the effects of the oral use of diclofenac sodium and ellagic acid on formation of postoperative adhesions in rats Studies have shown that agents with anti-inflammatory properties and antioxidant substances can prevent adhesion by decreasing oxidative stress. We compared and evaluated the effects of ellagic acid that has strong antioxidant and anti-inflammatory properties and the nonsteroidal anti-inflammatory diclofenac sodium on peritoneal adhesion development in our experimental study. Laparotomy was performed with a midline incision under general anesthesia and an adhesion model was created on the antimesenteric side of the cecum in Groups I, II, and III. Group I received 85 mg/kg ellagic acid and Group II, 50 mg/kg diclofenac sodium through the nasogastric catheter while Group III received no medication. Only laparotomy was performed in Group IV. The rats were sacrificed at the end of the 14th day. Following macroscopic scoring, tissue samples were removed and subjected to biochemical and histopathologic evaluation. The degree of adhesion and the malondialdehyde level were decreased (P < 0.05), and glutathione level increased (P < 0.05) in Group I compared to Group II and Group III. The effects of ellagic acid on the prevention of peritoneal adhesion were found to be stronger than diclofenac sodium. This can be explained by the fact that ellagic acid is a strong antioxidant and decreases oxidative stress with anti-inflammatory and anti-angiogenic effects.

Abstract:The aim of this study was to examine the histometrical and histological structures of goose (Anser anser) spleen.Six healthy female geese were used as material. Tissue samples taken from the spleen were processed routinely, and were then stained with H&E, Crossman's Triple stain and Toluidine blue stain. The spleen surrounded by capsules composed of connective tissue and parts of the capsules were observed increasingly thinning into the spleen as trabeculae. The red pulp area was distinguishable from the white pulp inside the organ; further, the lymph follicles appeared clearly within the white pulp. Histometric measurements revealed that the thickness of the capsules surrounding the organ ranged from 18 to 28 µm. The average thickness of the capsules was measured as 22 µm. The average number of lymph follicles was found to be 2.4 in 1.07 mm 2 . The average width and length of the lymph follicles were measured as 113 µm and 144 µm, respectively.The average diameter of the mast cells was found to be 6 µm. The average number of mast cells was found to be 1.4 in 1.07 mm 2 . Although the histological structures of the geese spleens seemed very similar to those of other animals in several respects, but some specific properties of geese spleens being more similar to that of mammalians were also observed.
