objective(s): reproductive dysfunction is a consequence of diabetes. diabetes is associated with changes in testicular tissue. sesame oil contains large amounts of polyunsaturated fatty acids and lignin with antioxidant activity, vitamin e, and monounsaturated fatty acid (mufa). the present study investigated the effects of sesame on testis histology and male reproductive parameters in streptoz...

Dear Editor-in-Chief   Pilomatrixoma is a benign tumor of hair follicle first described as calcifying epithelium (1). It accounts for 1% of all the benign skin tumors (2). It is a slow-growing, firm, dermal or subcutaneous neoplasm, usually measuring fewer than 3 cm in diameter. Pilomatricomas are considered benign; rarely recur after surgical excisi...

The survival of donor corneal epithelium was investigated in rabbits after they received unilateral 8 mm diameter lamellar keratoplasties with living donor tissue of a different sex from the host. Three weeks, 6 weeks, and 12 weeks postoperatively, cultured corneal epithelia, grown from 5 mm diameter central buttons, the adjacent 0.75 mm wide donor rings, the peripheral 10 to 13 mm diameter rin...

Background: Plant materials continue to play an important role in the maintenance of human health since antiquity. Phytoestrogens are naturally occurring plant substances that can either mimic or antagonize the action of endogenous estrogens. This study was conducted to investigate the effects of vitex agnus as a phytoestrogenic plants, essential oil on structure and morphology of seminiferous ...

background: sodium arsenite and/ or vasectomy may cause variation in sex hormones which affect pathophysiology of reproductive organs. objective: the aim was to investigate the morphological changes in structure of testis and hormonal imbalance in bilateral vasectomised rats treated with sodium arsenite. materials and methods: four groups of rats: bilateral vasectomy + sodium arsenite, bilatera...

  SUMMARY The testes of five wistar rats 2 months after bilateral vasectomy was compared with those of sham­operated controls. Aims were to determine whether there are any changes in the wistar rat testis after vasectomy. Two testis in the vasectomized group displayed histological changes, which consisted of depletion of germ cells, vacuolation in the epithelium, folding of basement membrane ...

Background: Cytotoxic therapy can lead to prolonged azoospermia or even sterility. In the present study, we investigated the morphological changes of mouse testes after gamma-Radiation. Methods: After anaesthetizing of NMRI mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. Four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+1...
