Daily treatment of aged ovariectomized
rats with human parathyroid hormone (1-84) for 12 months reverses bone loss and enhances trabecular and cortical bone strength.
Methods: The pregnant mice were ovariectomized
on the evening on the third day of pregnancy with a single injection of medroxyprogesterone acetate to induce delayed implantation (DI).
Ethanol also increased plasma prolactin levels and pituitary weight both in female rats with normal menstrual cycles and in rats whose ovaries had been removed (i.e., ovariectomized
rats) and promoted estradiol-induced development of prolactin-producing benign tumors (i.e., prolactinomas) in the pituitary (De et al.
Materials and Methods: Adult female rats were ovariectomized
bilaterally to induce estrogen deficiency.
Central administration of leptin to ovariectomized
ewes inhibits food intake without affecting the secretion of hormones from pituitary gland: evidence for a dissociation of effects on appetite and neuroendocrine function.
This pattern of increased BV and TV with no change in BV/TV reflects changes seen previously in the stifle joints of ovariectomized
females but was opposite to results seen previously in a destabilized stifle model [17,18].
administered aspirin at the doses of 8.93, 26.79 and 80.36 mg/kg/day to threemonth-old ovariectomized
RAL improves the endothelial function in ovariectomized
(OVX), aged, or hypertensive rats, ameliorates the hypertension-induced endothelial dysfunction by reducing the production of reactive oxygen species, and enhances endothelial nitric oxide-(NO-) dependent vasodilatation in vitro.
In this model, the female rats are ovariectomized
bilaterally and subjected to hormonal treatment (progesterone and estradiol) for 23 days to simulate the natural course of pregnancy of a rat.
In contrast, other studies have shown that chronic oral exposure to BPA does not alter memory processes of adult male or ovariectomized
(OVX) female rats [10,11].
The objective of this study was to investigate the role of periapical disease in inducing MRONJ using an ovariectomized
(OVX) mouse model.
Methods: Seventy-two female Sprague-Dawley (SD) rats, 3 months old, were divided into sham-operated group (n = 6) and an ovariectomized
(OVX) group (n = 66).
