    Atomic minerals are the smallest components of bone and the content of Ca, being the most abundant mineral in bone, correlates strongly with the risk of osteoporosis. Postmenopausal women have a far greater risk of suffering from OP due to low Ca concentrations in their bones and this is associated with low bone mass and higher bone fracture rates. However, bone strength is determined not only.

Subcutaneous administration of leptin attenuates bone loss in ovariectomized (ovx) rats by reducing bone resorption. However, in addition to its direct beneficial effects, leptin has been reported to have indirect (central nervous system-mediated) antiosteogenic effects on bone, which may limit the efficacy of elevated serum leptin to prevent estrogen deficiency-associated bone loss.

Zhanjiang Medical College, Guangdong Province, People's Republic of China (Received 3 March ) (Accepted 21 May ) Summary The object of this study was to determine whether prostaglandin Ez (PGEz) can prevent ovariectomy- induced cancellous bone loss, Thirty-five 3-month-old female Sprague-Dawley rats were divided into two by: The object of this study was to determine whether prostaglandin E., (PGE2) can prevent ovariectomy-induced cancellous bone loss.

Thirty-five 3-month-old female Sprague-Dawley rats were divided into two groups. The rats in the first group were ovariectomized (OVX) while the others received sham operation (sham-OVX). Get this from a library. Prostaglandin E₂ prevents ovariectomy-induced cancellous bone loss in rats.

The relative contribution of trabecular and cortical bone to the strength of human lumbar by: Prostaglandin E 2 (PGE 2) is a bone anabolic agent that has been shown to increase bone mass by significantly increasing bone formation over bone resorption.6 The skeletal anabolic effects of PGE 2 have been demonstrated in both young and adult intact male and female rats.6, 10, 11, 12, 18 When given to ovariectomized (ovx) or orchidectomized (orx) rats immediately following surgery, PGE 2.

Postmenopausal osteoporosis due to estrogen deficiency is associated with severe morbidity and mortality. Beneficial effects of conjugated linoleic acid (CLA) on bone mineral density (BMD) have been reported in mice, rats and humans, but the effect of long term CLA supplementation against ovariectomy-induced bone loss in mice and the mechanisms underlying this effect have not been studied by: 9.

To unveil the relationship between changes in BMD and bone marrow haematopoiesis in adult animals suffering from osteoporosis, we chose 3-month-old rats as experimental models.

Several previous studies showed that in rats, oestrogen levels decreased precipitously accompanied by bone mass loss following ovariectomy. The object of this study was to determine whether prostaglandin E2 (PGE2) can prevent ovariectomy-induced cancellous bone loss.

Thirty-five 3-month-old female Sprague-Dawley rats were divided into. Our findings indicate that ovariectomy-induced bone loss in the rat is accompanied by marked changes in the hematopoietic system, and that these changes are modulated by estrogen administration.

In spite of the negative finding with IL-1ra, the nature of the involvement of the hematopoietic system in the pathogenesis of bone loss due to ovarian hormone deficiency merits continued exploration. Ke HZ, Li M, Jee WSS (b) Prostaglandin2 prevents ovariectomy-induced cancellous bone loss in rat.

Bone 11–22 CAS. Abstract. The ovary is concerned with the secretion of steroid hormones and with the release of a mature ovum (ovulation). Ovarian function is controlled by hormones secreted by the anterior pituitary gland, namely follicle-stimulating hormone (FSH), luteinizing hormone (LH), and, to a greater or lesser extent depending upon the species, prolactin.In this study, we aim to investigate the effects of methylprednisolone, a glucocorticoid, on ovariectomy-induced bone loss in rats with a metyrosine-reduced amount of endogenous adrenaline and compare them with alendronate.
