OBJECTIVES Using ovariectomized rats, we examined the influence of combined exercise tolerance and natto intake on the bone loss inhibitory effect. METHODS We divided female Wistar rats into the following groups: Ovariectomy, Ovariectomy + Exercise, Ovariectomy + Natto Intake, Ovariectomy + Exercise + Natto Intake, and Pseudo-operative (Sham group). After conducting experiments on each group,...

MTW9, a transplantable mammary tumor in Wistar Furth rats, shows little growth unless host serum prolactin is increased. This study compares the response to ovariectomy of MTW9-MtT, a tumor developed in rats bearing the mammosomatotropic tumor MtTW10 (serum prolactin 500 to 7000 ng/ml) with MTW9-P developed in rats given chronic perphenazine treatment (4 mg/kg/day). Serum prolactin concentratio...

The present study evaluated and compared the oxidative stress status of dogs undergoing laparoscopic or open ovariectomy. Twelve healthy female dogs were divided into two groups according to the type of the surgical procedure, laparoscopic or open ovariectomy. Plasma total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) levels for the evaluation of oxidativ...

Background: Menopause occurs between the ages of 40 and 50, marks end a woman's menstrual cycle. A period time during which woman does not have monthly cycle for more than 12 months is known as post-menopause. Women may suffer challenges in their daily lives this period, such depression, anxiety, sleep loss, all can negative impact on quality life. decrease hormone production, estrogen progeste...

The aim of this study was to test the combined effect of a quality-controlled red clover extract (RCE) standardized to contain 40% isoflavones by weight (genistein, daidzein, biochanin A, and formononetin present as hydrolyzed aglycones) together with a modified alkaline supplementation on bone metabolic and biomechanical parameters in an experimental model of surgically-induced menopause. Spra...

OBJECTIVES Estrogen replacement therapy remains current as a therapeutic approach to treat menopausal symptoms and may significantly affect hormone-producing cells in the female pituitaries. The aim of this study was to examine the histological parameters of pituitary mammotrophs and prolactin secretion after chronic estradiol treatment in ovariectomized adult female rats, reflecting premature ...

BACKGROUND The plant Cissus quadrangularis (CQ) is used as an osteoprotective agent in Ayurveda, the Indian system of alternative medicine. The present study was done to validate the anti-osteoporotic role of the petroleum ether extract of CQ on ovariectomy-induced osteoporosis in rats. METHODS Female wistar rats were divided into five groups of six rats each; (1) The Normal control (NC) grou...

Epidemiological studies point to a beneficial influence of the female reproductive hormones on stroke risk in that women have a lower incidence of stroke prior to the menopause compared with men, but this difference weakens with age and stroke risk in women rises after the menopause. However, recent Women's Health Initiative trials in post-menopausal women report an increased stroke risk on hor...

OBJECTIVE To describe laparoscopic ovariectomy and salpingectomy in the African lioness (Panthera leo). STUDY DESIGN Descriptive clinical study. ANIMALS Female lions (n = 16). METHODS Lionesses were randomly divided into 2 groups: O = ovariectomy (n = 8) and S = salpingectomy (n = 8) for laparoscopic surgery. Two Veress needle placement techniques were used. RESULTS Laparoscopic ovariec...

Curcumae Radix (CR) and Glycyrrhizae Radix et Rhizoma (GR) extracts have been used as health supplements in traditional medicine. This study was performed to evaluate the effects of combined CR and GR extracts (CR+GR) on metabolic complications related menopausal symptoms. We found a significant results that CR+GR extracted using ethanol stimulated the growth of MCF-7 cells in estrogen activity...
