Introduction: Ovarian tumors have various histomorphological patterns. Histopathological examination plays an important role is classifying ovarian tumors for better prognosis. Ovarian tumors are classified into surface epithelial tumors, germ tumors and sex cord stromal tumors. This study was done to know various histomorphological patterns of ovarian tumors. Materials and Methods: Both retros...

Effect of respirable fly ash particles inhalation on lungs of rats was investigated by exposing them to respirable aerosols of size classified power plant fly ash at average concentrations of up to 14.4 +/- 1.77 mg/m3 for 4 hr/day for 28 consecutive days. A remarkable increase was found in blood eosinophil counts of fly ash exposed animals. Biochemical indicators of pulmonary damage viz. lactat...

This experiment was designed to study the effects of caffeine on histomorphology testes prepubertal male Wistar rats. Prepubertal rats (25-28 days old), weighing between 50-60 g were randomly divided into three treatment groups (B, C and D) control (A) ten each. Group A received distilled water while Groups B, C, D respectively given daily dose 50 mg/kg, 100 200 mg/kg dissolved in for 14 by gav...

Ammonium 2,3,3,3-tetrafluoro-2-(heptafluoropropoxy)-propanoate, developed for use as a polymerization processing aid in the manufacture of fluoropolymers, was tested for its potential chronic toxicity and carcinogenicity in a 2-year oral dosing study in Sprague-Dawley rats. Male rats were given daily doses of either 0, 0.1, 1 or 50 mg/kg; females were given either 0, 1, 50 or 500 mg/kg. Body we...

The aim of the present study was to observe the expression of sonic hedgehog (Shh) and Ptc signaling molecules in the lungs of newborn rats exposed to prolonged hyperoxia, and to explore the role of the SHH signaling pathway in hyperoxia‑induced lung injury. Newborn Sprague-Dawley rat pups were placed in chambers containing room air or oxygen above 95% for 14 days following birth. The rats were...

Gill histomorphological alterations were used to assess the effects of chronic exposure to HgCl2 on the yellowfin seabream, Acanthopagrus latus. In this regard, 90 A. latus were exposed to sublethal concentrations of HgCl2 (10, 20, 35 and 50 μg/L) for 3 weeks. Treated fish were erratic and showed respiratory distress. The most common morphological abnormalities included: filaments disorganizati...

OBJECTIVE Ischemia/reperfusion (I/R) injury is a major cause of acute organ dysfunction and I/R related acute renal failure is a common clinical problem. Diabetes mellitus is defined as a risk factor for the development of acute renal injury as diabetic nephropathy compromises the renal tolerance to ischemia. The aim of this study was to investigate the protective effect of magnesium sulfate in...
