histological and histochemical studies on the pancreas of goose (anser albifrons) were carried out using special staining and light microscope. the pancreas in goose is serous tubuloacinar gland having exocrine and endocrine part. smooth muscle fibres were absent in capsule of pancreas. acinar cells have bizonal shape. intralobular ducts, interlobular and main excretory ducts were present withi...

the ontogeny of the gill structure in starlet ( acipenser ruthenus ) was studied histologically from hatching up to 50 days post hatching (dph). based on the obtained results, the first developmental phase of the biological systems in this species was started from hatching with an intense organogenesis and the second phase from 9 dph with the beginning of exogenous feeding. the gill anlage was ...

introduction: in chick embryo, endodermal component of the liver becomes split into 2 diverticula in a short time. the anterior diverticulum lies to the left of the ductus venosus and the posterior one to its right side. as the liver primordium grows, it is invaded by the embryonic veins. based on the different incubation time periods and evolutionary origin of avian species, various times for ...

introduction: the present study used a histological evaluation method to examine the effects of pentoxifylline (ptx) on healing an experimentally-induced pressure sore in a rat model. materials and methods: there were 36 adult male rats used in this study. under general anesthesia and sterile conditions, we used forceps to create one pressure sore on each rat. a double layer of folded skin from...
