PURPOSE to determine the prevalence of histopathological changes, in human placentas, related to hypertensive syndromes. METHODS a transversal study that compares histopathological changes identified in 43 placentae from hypertensive pregnant women (HypPr), with the ones from 33 placentae from normotensive pregnant women (NorPr). The weight, volume and macroscopic and microscopic occurrence o...

AIM Nimesulide, a preferential COX-2 inhibitor has 20 times more selectivity towards COX-2 than that of COX-1. COX-2 selective inhibitors cause frequent nephrotoxicity and hepatotoxicity following their usage. This proposes a physiological role of COX-2 in kidney and liver. Not much attention has been focused on the role of COX-2 with respect to reproduction especially in male reproduction, and...

Dysfunctional uterine bleeding occurs in the absence of any pelvic pathology with disruption of normal patterns of endometrial stimulation. It is diagnosed by exclusion and is found more commonly in women around perimenopausal age and increases till menopause. Diagnosis is by histopathologic examination. Methods: Endometrial biopsies of 100 women in the reproductive and perimenopausal age were ...

Introduction: Some postgraduate students reported the presence of a nematode infection, presumably, Trichosomoides crassicauda in the urinary bladder of rats (Rattus norvegicus) from the animal house of Tehran University of Medical Sciences (TUMS). We prompted to explore the prevalence of this infection among the rats of animal houses belonging to medical and veterinary research centers in Tehr...

background: acyclovir (acv), a synthetic purine nucleoside analogue, is known to be toxic to gonads. objective: the current study evaluated cytotoxicity of acv on histopathological changes in testis tissue and serum testosterone and lipid peroxidation concentrations of male rats. materials and methods: animals were divided into five groups. one group served as control and one group served as co...

2,3,7,8-tetrachlorodibenzo-p-dioxin (tcdd) is a by-product o f t he trichlorophenol (herbicide) production and is also produced through a variety of combustion processes. it appears that tcdd is a ubiquitous chemical, particularly in industrialised countries, and the liver is the target organ of its toxicity. the prominent hepatotoxic effect of tcdd is progressive centrilobular necrosis. the is...

background: immunotherapy is the only specific treatment for scorpion envenomation. in the present study, the protective effects of polyvalent antivenom against histopathological complications in kidneys and marker changes (bun and creatinine) induced by mesobuthus eupeus (me) scorpion venom was investigated in anesthetized rabbits. methods: twenty four rabbits were randomized into four groups:...

Background: Phyllodes tumors (PTs) are uncommon biphasic fibroepithelial neoplasms of the breast occurring in elderly females with a peak incidence between 45 and 49 years. Depending on various histological criteria, they are subdivided into benign, borderline, and malignant forms. Metaplastic changes occur, but are quite infrequent and cystic squamous metaplasia is ve...
