1. Ovarian hormones influence immune response to Staphylococcus aureus infection
ABSTRACT Objective: Staphylococcus aureus infections remain associated with considerable morbidity and mortality in both hospitals and the community. There is little information regarding the role of ovarian hormones in infections caused by S. aureus. The aim of this study was to evaluate the effects of ovariectomy in the immune response induced by S. aureu

2. Modelo de indução de osteoporose em coelhas - avaliação radiográfica
ABSTRACT In order to establish a bone loss induction model in rabbits to study osteoporosis, 18 rabbits underwent ovariectomy and received methylprednisolone 1mg/kg intramuscularly on alternate days for two weeks. Immediately before ovariectomy up to 42 days after methylprednisolone administration, radiographs of the right olecranon were taken in the mediola

3. A SERM increasing the expression of the osteoblastogenesis and mineralization-related proteins and improving quality of bone tissue in an experimental model of osteoporosis
Abstract Raloxifene is an antiresorptive drug, selective estrogen receptor modulator (SERM) used in the treatment of osteoporosis. Objective To evaluate proteins related to bone repair at the peri-implant bone in a rat model of osteoporosis treated with raloxifene. Material and Methods 72 rats were divided into three groups: SHAM (healthy animals), OVX (ov

4. Effect of ovariectomy in bone structure of mandibular condyle
Abstract Purpose: To evaluate the bone structure of the mandibular condyle through an animal model, after ovariectomy. Methods: Thirty-six female Wistar rats were divided into 2 groups. The OVX group was submitted to bilateral ovariectomy, the SHAM group underwent the same surgical treatment, but without removal of the ovaries. After 90, 105 and 135 days

5. Effects of continual intermittent administration of parathyroid hormone on implant stability in the presence of osteoporosis: an in vivo study using resonance frequency analysis in a rabbit model
Abstract Objective: This study aimed to evaluate the effects of continual intermittent administration of parathyroid hormone (PTH) on implant stability in the presence of osteoporosis, using rabbit models. Material and Methods: Fifteen female New Zealand white rabbits underwent ovariectomy and were administered glucocorticoids to induce osteoporosis, follo

6. Short term sodium alendronate administration improves the peri-implant bone quality in osteoporotic animals
Abstract Sodium alendronate is a bisphosphonate drug that exerts antiresorptive action and is used to treat osteoporosis. Objective The aim of this study was to evaluate the bone repair process at the bone/implant interface of osteoporotic rats treated with sodium alendronate through the analysis of microtomography, real time polymerase chain reactions and

7. Estrogen deficiency in ovariectomized rats: can resistance training re-establish angiogenesis in visceral adipose tissue?
OBJECTIVE: The purpose of this study was to investigate the effects of resistance training on angiogenesis markers of visceral adipose tissue in ovariectomized rats. METHOD: Adult Sprague-Dawley female rats were divided into four groups (n=6 per group): sham-sedentary, ovariectomized sedentary, sham-resistance training and ovariectomized resistance trainin

8. Chenopodium ambrosioides L. extract prevents bone loss
ABSTRACT PURPOSE: To evaluate the effect of the Chenopodium ambrosioides L (mastruz) extract for preventing bone loss and bone metabolism in ovariectomized rats. METHODS: Twelve rats were subjected to bilateral ovariectomy for inducing osteoporosis. After surgery, they were divided into two groups: Ovariectomy-control group (G1, n=6), receiving 0.5 ml dist

9. The low-level laser on acute myositis in rats
ABSTRACT PURPOSE: To analyze the effects of the low-level laser therapy in the acute myositis induced in rats. METHODS: Twelve rats were subjected to bilateral ovariectomy for inducing osteoporosis. After surgery, they were divided into two groups: Ovariectomy-control group (G1, n=6), receiving 0.5 ml distilled water by gavage for 30 days, and Ovariectomy

10. Use of Ursodeoxycholic Acid on Post-menopausal Obesity, Hepatic steatosis and Plasma Profile as an Alternative Treatment for Hormone Replacement Therapy
ABSTRACT The aim of this study was to evaluate the efficacy of the ursodeoxycholic acid (UDCA) as an alternative treatment for menopause pathologies. For this, female Swiss-CD-1 mice were ovariectomized (OVX); SHAM operated mice served as controls. Ten weeks after operation, each group of mice was treated during four weeks with either UDCA, or 17(-estradiol+

11. Hormonal therapy with estradiol and drospirenone improves endothelium-dependent vasodilation in the coronary bed of ovariectomized spontaneously hypertensive rats
Drospirenone (DRSP) is a progestin with anti-aldosterone properties and it reduces blood pressure in hypertensive women. However, the effects of DRSP on endothelium-dependent coronary vasodilation have not been evaluated. This study investigated the effects of combined therapy with estrogen (E2) and DRSP on endothelium-dependent vasodilation of the coronary

12. Whole-body vibration improves fracture healing and bone quality in rats with ovariectomy-induced osteoporosis
PURPOSE: To investigate the effect of vibration therapy on the bone callus of fractured femurs and the bone quality of intact femurs in ovariectomized rats. METHODS: Fifty-six rats aged seven weeks were divided into four groups: control with femoral fracture (CON, n=14), ovariectomized with femoral fracture (OVX, n=14), control with femoral fracture plus v
