Purpose: To investigate the effect of puerarin on symptoms depression in ovariectomized female rat model, and mechanism action involved.
 Methods: Ninety healthy Sprague Dawley (SD) rats were assigned to five groups: sham, low-dose puerarin, medium-dose high-dose groups, with 18 per group. Changes levels dopamine (DA), norepinephrine (NA), 5-hydroxytryptamine (5-HT), apoptosis-related prot...

Background: Osteoporosis one of the postmenopausal symptoms is characterized by bone loss. There is a link between excessive reactive oxygen species (ROS) formation, estrogen deficiency due to cessation of ovarian function and bone loss. Free radicals are responsible for causing osteoblast apoptosis and reducing osteoblastogenesis in bone remodeling. Vitamin E is a potent antioxidant with the a...

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): the aim of this study was to observe the influence of phytoestrogen α-zearalanol on ovariectomy-induced postmenopausal osteoporosis in rats. materials and methods:40 sd female rats were randomly divided into four groups: sham group, ovx group (ovariectomized and fed estrogen), α-zearalanol group (ovariectomized and fed α-zearalanol) and untreated group (ovariectomized). three week...

BACKGROUND Diabetes mellitus type 2 and osteoporosis are major health problem, especially in postmenopausal women. Glimepiride is a third-generation sulfonylurea derivative and is used as a first-line drug in the treatment of type 2 diabetes mellitus. The effect of this drug on bone tissue is unknown. The aim of the present study was to investigate the influence of glimepiride on the skeletal s...

Objective: The aim of this study was to investigate the possible effect of sex steroid deficiency on the rat tongue mucosa as well as the effect of its replacement. Methods: We chose 21 sexually virgin female Wistar albino rats in this study. We divided the model rats into 3 groups: Group-1:Control, Group-2: Sham-operated (bilaterally ovariectomized), and Group-3: Sham-operated, in addition we ...

objective: melanocortin-4 receptor (mc4r) and agouti-related peptide (agrp) are involved in energy homeostasis in the rat. the aim of the present study was to evaluate the expression of mc4r and agrp mrnas in arcuate nucleus (arc) during long term malnutrition of female ovariectomized rats. materials and methods: ten female ovariectomized rats were divided into two equal groups (n=6) of normal ...

background: the preparation of endometrium for embryo reception and implantation are controlled by ovarian hormones. these hormones have distinct cyclical changes during estrus cycle. objective: the aim of this study was to evaluate the changes in morphology and morphometrical indices of endometrium by daily injections of estrogen and progesterone in ovariectomized mouse. materials and methods:...

The risks associated with hormone replacement therapy, especially cardiac diseases in postmenopausal women, have prompted extensive studies for other preventive or therapeutic alternatives. We investigated the cardioprotective effects of exercise training on the changes in cardiac myofilament Ca2+ activation in 10-wk-old ovariectomized rats. The exercise groups were subjected to a 9-wk running ...

The authors report the generation, structure and function of a fully humanized, humanized antibody that profoundly inhibits follicle-stimulating hormone (FSH) actions in cell-based assays. Administration to ovariectomized mice prevented bone loss also accumulation adipose tissue when fed high-fat diet (HFD).
