Physical activity and risedronate sodium have effects on metabolic bone diseases, maintaining the integrity of bone tissue. Our objective was to evaluate the effects of swimming associated with risedronate as a prophylactic means in osteopenic bone of ovariectomized rats. A total of 24 animals of the Wistar strain were used and separated into four groups containing six animals: Ovariectomy (OVX...

Experiments were designed to determine how ovariectomy modulates mitogenic factors in platelets and how these factors affect proliferation of coronary arterial smooth muscle. Platelet-derived growth factors (PDGFAB and PDGFBB), transforming growth factors (TGF 1 and 2), and vascular endothelial growth factor (VEGF165) were quantified in platelet lysates and platelet -poor plasma (PPP) from adul...

The number of follicles were compared in different developmental stages after the cryopreservation of human ovarian tissue by open freezing system followed by xenotransplantation into severe combined immunodeficient (SCID)-mice under stimulation, with and without ovariectomy. Ovarian tissue, cryopreserved for fertility preservation was partly examined by LIVE/DEAD viability staining or was tran...

Bilateral ovariectomy and dietary administration of the retinoid N-(4-hydroxyphenyl)retinamide (4-HPR) are both effective inhibitors of chemical carcinogenesis in the rat mammary gland. The present study was designed to determine whether an enhanced inhibitory effect is obtained with combined ovariectomy and 4-HPR administration, compared to either treatment alone. In separate experiments, 50-d...

Postmenopausal disorders are frequently observed in various organs, but their relationship with estrogen deficiency and mechanisms remain unclear. As tissue-specific stem cells have been found to express estrogen receptors, we examined the hypothesis that estrogen deficiency impairs stem cells, which consequently contributes to postmenopausal disorders. Six-week-old C57BL/6 female mice were ova...

Experiments were designed to determine how ovariectomy modulates mitogenic factors in platelets and how these factors affect proliferation of coronary arterial smooth muscle. Platelet-derived growth factors (PDGF(AB) and PDGF(BB)), transforming growth factors (TGF-beta(1) and TGF-beta(2)), and vascular endothelial growth factor (VEGF(165)) were quantified in platelet lysates and platelet-poor p...

objective(s): the present study aims at examining the motor coordination performance, serum and cerebellar estrogen, as well as erβ levels, of ovariectomized rats (as menopausal model) following regular exercise. materials and methods:ten female sprague dawley ratsaged 12 weeks old were randomly divided into two groups; all of which underwent ovariectomy. the first group was treated with regula...

objective: estrogen deficit following menopause results in cognitive behaviors impairment. severity of these impairments in menopause women suffer with cerebral hypo perfusion/ischemia (hi) cause the brain damage and neuronal death. this study aimed to evaluate the effects of pomegranate seed extract (pgse) on avoidance memories after permanent bilateral common carotid arteries occlusion (2ccao...

The aim of this study was to estimate a bone density of the mandible and spine in experimental model of postmenopausal osteoporosis. Female Wistar rats were the investigative material. Rats were qualified for following groups: CL control, SH sham operated, OV after ovariectomy, OVH after ovariectomy receiving 17β-estradiol in three different doses (1.25, 12.5, 125 μg) during seven weeks. After ...

Purpose. Study of periodontoprotective properties preventive complexes based on calcium, quercetin, vitamins, macro- and microelements in ovariectomized rats with alimentary deficiency protein calcium. Materials methods. The study was conducted 32 female which pathology periodontal bone tissue simulated due to hipoestrogenicity; as well the prevention said biologically active calcium citrate fr...
