Introduction Menopause is an independent risk factor for cardiovascular disease (CVD). Physical exercise and soybean diets have been suggested to reduce the risk of CVD in postmenopausal women. The purpose of this study was to investigate the effects of combined resistance and endurance (RE) training and soy extract (SOY) supplementation, both known to improve endothelial function, on expressio...
Effects of dietary protein restriction and ovariectomy on plasma concentrations and hepatic messenger RNA (mRNA) of insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding proteins (IGFBP) were investigated in young female rats. Ovariectomy increased plasma IGF-I concentration in rats fed on either a 50 g casein/kg diet (protein-restricted diet) or a 200 g casein/kg diet (co...
OBJECTIVES The loss of ovarian function in women through aging or oophorectomy is often associated with the development of vaginal hyperalgesia that can be alleviated with estrogen replacement. This study examined if ovariectomy in rats would similarly give rise to vaginal hyperalgesia, and, if so, whether estrogen replacement would alleviate it. METHODS Female rats were trained to perform an...
OBJECTIVE The aim of this study was to examine the effects of ovariectomy and ovariectomy followed by estradiol benzoate administration on the ultrastructure of pinealocytes in female rat. DESIGN For this purpose 15 female Wistar rats were used. Animals were divided into three groups. Group I and II were designated as sham-ovariectomized (control) and ovariectomized, respectively. Group III w...
Objective(s): The role of isoflavones in pulmonary structure and function during menopause is not well studied. Moreover, the important role of estrogen in the physiological function of respiratory system has been revealed. Genistein, as an isoflavone, mimics estrogenic in diabetic and ovariectomized rats. Here, we hypothesized that genistein would reverse changes in the protein expression leve...
objective(s): studies have reported that whole body vibration (wbv) played a vital role in bone remodeling. circulating serotonin is also involved in negative regulating bone mass in rodents and humans. however, both wbv and inhibition of serotonin biosynthesis may suppress receptor activator of nuclear factor-kappab ligand (rankl)-induced osteoclastogenesis in vitro . the purpose of the curren...
background: the effect of ovariectomy and accompanying sudden loss of circulating gonad hormones on spatial learning performance in the young adult rats was examined. we hypothesized that spatial learning and memory in a considerable number of women who undergo a surgical menopause and estrogen deprivation before their natural menopause be impaired. methods: in this study, we used 26 wistar rat...
to follow-up the present study, 40 mature female rats were used. the animals were divided into test,control and sham groups. the rats in the test group were laparotomized and unilateral ovariectomy was done. on the 1st and 2nd met-oestrous after operation, the tissue samples were dissected out and processed for histological study. the intact ovary in the test group underwent a significant (p
