Ovarian neoplasia in the Sprague-Dawley rat.
Macroscopic and microscopic characteristics of 210 spontaneous ovarian tumors from 7748 Sprague-Dawley rats are described. The tumors were classified as tubular adenoma, anaplastic adenocarcinoma, papillary cystadenoma, papillary cystadenocarcinoma, mesothelioma, sertoliform tubular adenoma, Sertoli's cell tumor, granulosa cell tumor, thecal cell tumor, polycystic sex cord/stromal tumor, and li...
متن کاملThe Effect of Moderate Intensity Running Exercise on Femoral Bone Microarchitectures in Ovariectomized Sprague-Dawley Rats
Background & Objective: One of the most serious health problems is osteoporosis and it is mandatory to find preventive methods to confront this difficulty. Non-pharmacological methods are in priority due to less side effects. This study investigated the effect of treadmill running exercise on bone microarchitectures in female osteoporotic rats induced by ovariectomy. Materials & Methods: 30 rat...
متن کاملVarious Dosages of BMP-2 for Management of Massive Bone Defect in Sprague Dawley Rat
Introduction: The use of BMP-2 plays an important role in the treatment of extensive bone defect. However, data about the optimal dosage of BMP-2 in the massive bone defect cases is rare. Material and Method: Twenty-five SD rats were randomly divided into a control group ofhydroxyapatite (HA) alone (Group I), HA+BMP-2 1µg/mL (Group II), HA+BMP-2 5 ug/mL (Group III), HA+BMP-2 10 µg/mL (Gro...
متن کاملCentrally administered MTII affects feeding, drinking, temperature, and activity in the Sprague-Dawley rat.
MTII, an agonist of melanocortinergic receptors, is a well-documented anorexigenic agent in rats. Many investigators have reported its effects on feeding without considering concurrent alterations in other behaviors. Accordingly, we performed studies to simultaneously measure nocturnal feeding, drinking, activity, and temperature of rats after intracerebroventricular (third ventricle) administr...
متن کاملEstrogen and tamoxifen modulate cerebrovascular tone in ovariectomized female rats.
Postmenopausal estrogen deficiency increases the incidence of cerebrovascular disease. However, hormone replacement therapy is associated with an increased cardiovascular risk. Tamoxifen is a selective estrogen receptor modulator with estrogenic effects on cardiovascular risk factors, but its long-term impacts on cerebral vasculature are unknown. We hypothesized that chronic 17beta-estradiol or...
