It has been demonstrated in reflex-intact animals that the sensitivity to calcitonin gene-related peptide (CGRP) is increased during pregnancy and that this action is mediated by sex steroids but not by nitric oxide (NO). We assessed the effects of CGRP in the following groups of anesthetized ganglion-blocked rats: 1) pregnant, 2) ovariectomized, and 3) ovariectomized and treated with estradiol...
OBJECTIVES Compare the effect of different doses of red maca on gamma interferon (IFN-γ) levels in ovariectomized rats (OVX). MATERIALS AND METHODS Adult female rats were randomly divided into the following six groups: Group 1: pseudo-ovariectomized rats (PO); Group 2: OVX rats; Group 3: OVX rats treated with 4 ug/kg estradiol; and Group 4, 5 and 6: OVX rats treated with red maca extracts wit...
Background: World-renowned as primary healthcare, traditional medicine often represents the only therapeutic resource for many communities with very low incomes, although it shows valuable benefits. The objective of this investigation was to evaluate medicinal plants used treat infertility in Nyong & So’o Division (Cameroon) and effect Mammea africana, most commonly plant extract, on reprod...
This study evaluated protection by selenium (Se) in the bone repair process in ovariectomized rats after irradiation. For such purpose, 80 ovariectomized female Wistar rats were randomly divided into 4 experimental groups: ovariectomized (Ov), Ov/Se, Ov/irradiated (Irr) and Ov/ Se/Irr. A bone defect was created on the tibia of all animals 40 days after ovariectomy. Two days after surgery, only ...
Artemisia princeps (AP) is a flowering perennial used as a traditional medicine and dietary supplement across East Asia. No study has yet assessed its effects on synaptic plasticity in hippocampus and much less in a model of ovarian hormone deficiency. We examined the influence of chronic oral AP ethanol extract treatment in ovariectomized rats on the induction of long-term depression in a repr...
We have compared the effects of two types of physical training on the cardiac autonomic control in ovariectomized and sham-operated rats according to different approaches: double autonomic blockade (DAB) with methylatropine and propranolol; baroreflex sensibility (BRS) and spectral analysis of heart rate variability (HRV). Wistar female rats (±250g) were divided into two groups: sham-operated a...
P-181: Protective Role of Vitamin E As An Alternative Treatment for Ovariectomized Osteoporotic Rats
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...
During osteoporosis therapy with alendronate, esophagitis and stomach ulceration may occur, requiring the concurrent use of drugs which decrease gastric juice production. The aim of the present study was to investigate the effect of concurrent administration of proton pump (H+/K+ATP-ase) inhibitors: omeprazole or pantoprazole and alendronate on bone remodeling in ovariectomized rats. The experi...
We studied the effect of exercise on ovariectomized mature multiparous rats. Old retired breeder SpragueDawley rats were ovariectomized and divided into a sedentary and a treadmill-trained (20 weeks) groups. Exercise training decreased body weight gain, fat weight around the uterus and plasma triglyceride content significantly compared with the sedentary group, but food intake was unaffected. E...
BACKGROUND Loss of bone quality and deterioration of articular cartilage are commonly seen after menopause. While exercise may protect against tissue degeneration, a clear link has yet to be established. The aim of the present study is to investigate the influence of long-term treadmill exercise on changes in bone mass and articular cartilage in ovariectomized rats. METHODS Sixty female Sprag...
