The surface structures and gland cells of the posterior rosette organ of Gyrocotyle urna Grube et Wagener, 1852, a member of the group presumed to be the most basal of the tapeworms (Cestoda: Gyrocotylidea), was studied by scanning electron and transmission electron microscopy. Surface structures on the outer (oriented away from the intestinal wall) and inner (in contact with the intestinal wal...

abstract background: the children with middle ear effusion need repeated re-tympanostomies. adenoidectomy is an effective surgical intervention in the management of chronic otitis media with effusion in conjunction with in-sertion of tympanostomy tubes (tts). to find out whether tts in different positions decrease the rate of re-tympanostomies study was done. methods: the present study retrospe...

background: recent attention has focused on the expression of integrin molecules within the endometrium, and their relation to infertility. objective: the present prospective study was undertaken to determine whether the endometrium of women with unexplained infertility differs in the expression of very late activation antigens (vla) from the endometrium of normal fertile women. methods: thirty...

background: sparganosis is caused by the invasion of spirometra sparganum into various tissues/organs. subcutaneous sparganosis can be diagnosed by biopsy , while visceral/cerebral sparganosis is not easy to be diagnosed. the diagnosis de-pends largely on the detection of specific anti-sparganum antibodies. t he specific-ity of the elisa could be increased by using s. mansoni sparganum excretor...

Background: The current advance in liver anatomy and surgery is based on the new concept of subdivision. The area fed by each tertiary branch was cone-shaped unit and the cone unit resection indicated resection on segments smaller than Couinaud’s segments. Material and methods: Portobiliary casts were obtained from 27 out of 30 cadaveric liver specimens, using injection-corrosive method. Under ...

A 32-year-old woman had several brownish and pruritic lesions over her left buttock and leg that had been present since she was 12 years old. She observed a progressive increase in size and number of the lesions, with increased sweating on and around them. Examination revealed several brownish, irregular nodules, 1–1.5 cm in diameter, and firm to palpation, along the lower left limb and followi...

The model proposed by Diamond and Bossert [1] for isotonic water transport has received wide acceptance in recent years. It assumes that the local driving force for water transport is a standing osmotic gradient produced in the lateral intercellular spaces of the epithelial cell layer by active solute transport. While this model is based on work done in absorptive epithelia where the closed to ...

mullerian duct anomalies (mdas) are relatively common disorders that are particularly responsible for obstetrical complications and have a prevalence of about 3%-4% in the general population (1, 2). uterine malformations may result from arrested development of the mullerian ducts, failure of fusion of the mullerian ducts or failure of resorption of the median septum (1, 2).

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...
