The preventive effect of the herbal formulation OST-6 (Osteocare) on the progress of bone loss induced by ovariectomy and concurrent calcium deficiency was studied in rats. Ovariectomy (OVX) and calcium deficiency (CD) resulted in bone loss as evident from decreased femoral weight and density. Treatment with OST-6 at a dose of 250 mg/kg body wt twice a day orally for a period of 16 weeks signif...

Glucocorticoids (GCs) are master regulators of systemic metabolism. Intriguingly, Cushing's syndrome, a disorder of excessive GCs, phenocopies several menopause-induced metabolic pathologies. Here, we show that the glucocorticoid receptor (GR) drives steatosis in hypogonadal female mice because hepatocyte-specific GR knockout mice are refractory to developing ovariectomy-induced steatosis. Intr...

Hormone dependency of the N-nitrosomethylurea-induced mammary tumor in rats has been demonstrated by ovariectomy. Tumors showing a clear reduction in size in response to ovariectomy have been used in an ultrastructural study. Histologically, the tumor is an adenocarcinoma. The multilayered tumor parenchyma contains myoepithelial cells and highly and less-well-differentiated cells. The adluminal...

Calcium supplements are widely used to prevent osteopenia and osteoporosis can be as a treatment along with other drugs. The effect of this supplement seen from the improved bone quality. focus in study was analyze quality femur based on mineral maturity degree crystallinity ovariectomized Rattus norvegicus where various nano calcium phosphate diets (1.0×; 1.5× 2.0× normal needs, respectively c...

The Effect of Substance P on Ovariectomy-induced Memory Deficits in Rats Jamie L. Haga The present experiment was designed to test whether pretreatment with substance P would affect ovariectomy-induced memory deficits in rats for retention in the Morris water maze. Adult female Sprague-Dawley rats were divided to two groups: (1) control (received saline) and (2) experimental group (received sub...

AIM Estradiol treatment regulates estrogen receptor (ER) level in normal rat liver. However, little information is available concerning the role of estrogen in regulating liver ER in hepatic fibrosis in rats. The present study was conducted to determine whether estradiol treatment in CCl4-induced liver fibrosis of female and ovariectomized rats altered liver ERalpha and its mRNA expression, and...

Background: A prospective randomized study was used to compare surgery times for laparoscopic ovariectomy and salpingectomy in female African lion (Panthera leo) (n = 14) and cheetah (Acinonyx jubatus) (n = 20) and to compare the use of a multiple portal access system (MPAS) and single portal access system (SPAS) between groups. Two different portal techniques were used, namely MPAS (three sepa...

Laparoscopic ovariohysterctomy is considered as an appropriate substitute for open procedure because of the less morbidity associated with its use (Austin et al., 2003). Smaller incision, less complication and decreased post-operative pain are main advantages of laparoscopic ovariohysterectomy (Davidson et al., 2004). Ovariectomy in pig is a very common surgical procedure in Mizoram. People in ...

introduction: the role of ovarian hormones and nitric oxide (no) in learning and memory and their interaction has been widely investigated. the present study carried out to evaluate different effect of l-name on spatial learning and memory of ovariectomized (ovx) and sham operated rats. methods: 32 rats were divided into 4 groups: 1) sham 2) ovx 3) sham-ln and 4) ovx-ln. the animals of groups 3...

Bilateral laparoscopic ovariectomy performed in standing mares eliminates many of the potential complications associated with traditional methods of ovariectomy. When compared with previously described techniques, the technique described here requires minimal laparoscopic instrumentation. Dissection of the ovarian pedicle prior to ligation is considered essential to ligature security. Authors’ ...
