Calcitriol supplementation in ovariectomized rats for 8 weeks reduce osteoporosis risk and safe for kidney depend a proper dose. The objective of the research was to study the efectivity of high dose calcitriol for osteoporosis prevention and safe for kidney  in ovariectomized Wistar rats. Fifteen female Wistar rats at 8 weeks of age were randomly divided into three  groups of five which were sham operated rats (KN), ovariectomized rats (KOV), and ovariectomized rats+calcitriol supplementation 200ng/day (OVD200). After 8 weeks of treatment, blood samples were taken from plexus orbitalis medialis for estrogen analysis. All rats were then euthanized, left tibia and left kidney were taken for histopathological examination using hematoxylin and eosin stain. Immunohistochemistry using anti TRAP5b monoclonal antibody was also done for left tibia by streptavidin-biotin.  The results showed that estradiol level of KOV was significantly decreased compared with KN (P<0.05), meanwhile, estradiol levels of OVD200 were not significantly different compared with KOV. Histopathologic figure of kidney in KOV was not different compared with KN. Glomerulus was surrounded by Bowman‘s capsule, proximal and distal convoluted tubulus were lined with typical cuboidal epithelium. Immunohistochemistry result of proximal tibial epiphysis in KOV were shown more tartrate resistant alkaline phosphatase 5b (TRAP5b) expression in trabecular bone, which was located in bone marrow space, and trabecular speculum surface as well. Meanwhile, proximal tibia epiphysis in OVD200 had less tartrate resistant alkaline phosphatase 5b (TRAP5b) expression compared with KOV. Histopathologic figure  of proximal tibia epiphysis in group OVD200 was shown more trabecular bone speculum and less adipocyte in the bone marrow compared with KOV. Histopathologic figure of kidney in OVD200 was showed glomerular  hypertrophy and atrophy, as well as protein deposits in proximal convoluted tubules epithelium.  In conclusion, calcitriol supplementation 200ng/day in ovariectomized rats for 8 weeks prevented osteoporosis risk but trigger urolithiasis. Key words :  : Calcitriol, osteoporosis, ovariectomized rats, urolithiasis

Trabecular Bone Mass

Alterations in trabecular bone were observed in growing male Wistar rats after 18.5 days of orbital flight on the COSMOS 1129 biosatellite. Spaceflight induced a decreased mass of mineralized tissue and an increased fat content of the bone marrow in the proximal tibial and humeral metaphyses. The osteoblast population appeared to decline immediately adjacent to the growth cartilage-metaphyseal junction, but osteoclast numbers were unchanged. These results suggested that bone formation may have been inhibited during spaceflight, but resorption remained constant. With the exception of trabecular bone mass in the proximal tibia, the observed skeletal changes returned to normal during a 29-day postflight period.

This study was conducted to assess the effectiveness of a diet contained fresh anchovies and calcitriol supplementation for 6 weeks to prevent osteoporosis in ovariectomized rats. Fifteen Wistar rats aged 8 weeks were divided randomly into 3 groups (normal/K, ovariectomized/Ov, andovariectomized + calcitriol/OVD), 5 mice each. Group K and Ov rats were fed with fresh anchovies, while the OVD group was fed with freshanchovies + calcitriol. At the age of 15 weeks, all mice were done for euthanasia, then left femur was collected for immunohistochemistryexamination of tartrate resistant acid phosphatase5b (TRAP5b). The detection of (TRAP5b) was conducted using a monoclonal ant ibody antiTRAP5b, and detected using a streptavidin-biotin. The results showed that the metaphysis part of distal femur bone of mice group K, Ov, andOVD were positive TRAP5b stained with brown color on trabecular bone in bone marrow cavity and trabecular spiculum surface, but rats ingroup K and Ov had extensive bone marrow cavity and normal trabecular spiculum, whereas OVD group showed bone marrow cavity dilation,accumulation of adipocytes in the bone marrow cavity, and shorter the spiculum of trabeculae. It can be concluded that fresh anchovies diet andcalcitriol supplementation for 6 weeks are not effective in preventing osteoporosis in ovariectomized rats.Key words: calcitriol, femur, ovariohisterectomy

OBJECTIVE The use of intrawound vancomycin powder in spine surgery has been shown to decrease the rate of surgical site infections; however, the optimal dose is unknown. High-dose vancomycin inhibits osteoblast proliferation in vitro and may decrease the rate of solid arthrodesis. Bone marrow–derived mesenchymal stem cells (BMSCs) are multipotent cells that are a source of osteogenesis in spine fusions. The purpose of this study was to determine the effects of vancomycin on rat BMSC viability and differentiation in vitro. METHODS BMSCs were isolated from the femurs of immature female rats, cultured, and then split into two equal groups; half were treated to stimulate osteoblastic differentiation and half were not. Osteogenesis was stimulated by the addition of 50 µg/mL l-ascorbic acid, 10 mM β-glycerol phosphate, and 0.1 µM dexamethasone. Vancomycin was added to cell culture medium at concentrations of 0, 0.04, 0.4, or 4 mg/mL. Early differentiation was determined by alkaline phosphatase activity (4 days posttreatment) and late differentiation by alizarin red staining for mineralization (9 days posttreatment). Cell viability was determined at both the early and late time points by measurement of formazan colorimetric product. RESULTS Viability within the first 4 days decreased with high-dose vancomycin treatment, with cells receiving 4 mg/mL vancomycin having 40%–60% viability compared to the control. A gradual decrease in alizarin red staining and nodule formation was observed with increasing vancomycin doses. In the presence of the osteogenic factors, vancomycin did not have deleterious effects on alkaline phosphatase activity, whereas a trend toward reduced activity was seen in the absence of osteogenic factors when compared to osteogenically treated cells. CONCLUSIONS Vancomycin reduced BMSC viability and impaired late osteogenic differentiation with high-dose treatment. Therefore, the inhibitory effects of high-dose vancomycin on spinal fusion may result from both reduced BMSC viability and some impairment of osteogenic differentiation.

The objective of this research was to study the effectiveness of calcitriol and ethynil ethyl estradiol combinations to decrease osteoporosis and endometrial cancer risks in ovariectomized Wistar rats. Twenty five 8-week old female Wistar rats were randomly divided into five groups (normal controlled rats/NK, ovariectomized rats/OVK, ovariectomized rats + calcitriol supplementation/OVD, ovariectomized rats + ethynil ethyl estradiol supplementation/OVE, and ovariectomized rats + calcitriol + ethynil ethyl estradiol supplementation/OVDE). At the end of the study, all rats were weighed and euthanized with 10% ketamine and 2% xylazine. Uterus and left femur were taken and fixed in 10% formaldehyde solution for histopathological examination using hematoxylin and eosin stain. Uterus was weighed before the fixation. The results showed that the percentage of uterus weight in OVK was significantly decreased compared to NK. Meanwhile, the percentage of uterus weight in OVDE was significantly increased compared to OVK. Histopathological features of the uterus in OVK were atrophy, reduction of myometrial and endometrial layers thickness, and formation of cuboidal epithelium in the endometrial lumen. However, the thickness of myometrial and endometrial layers in OVDE were increased, and its endometrial lumen was lined with metaplastic and hyperplastic squamous cell. Histopathological features of distal femur epiphysis in OVK ras showed fewer trabecular spiculums and more adipocyte in the bone marrow compared to NK. However, OVDE had more trabecular bone spiculum and less adipocyte in the bone marrow compared to OVK. In conclusion, the combination of calcitriol and ethynil ethyl estradiol supplementation could reduce osteoporosis, but increased the endometrial cancer risk in ovariectomized Wistar rats.

In the present study the hepatoprotective efficacy of two edible macrofungi Dacryopinax spathularia and Schizophyllum commune has been assessed against CCl4-induced hepatotoxicity in albino wistar rats. The administration of CCl4(1ml/Kg) resulted into significant (p<0.05) rise in the levels of liver function marker enzymes Alanine Transaminase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP) and bilirubin and decrease in the levels of total protein and albumin in blood. On administration of low dose (250mg/Kg) and high dose (500mg/Kg) of both macrofungal extracts in different hepatotoxic group of rats, the serum levels of AST, ALT, ALP and bilirubin significantly (p<0.05) lowered down and the levels of total protein and albumin significantly (p<0.05) increased in comparison to the hepatotoxic group of rats, reflecting the hepatoprotective impact of both the extracts.

This studyevaluated protection by selenium (Se) in the bone repair process in ovariectomized rats after irradiation. For such purpose, 80 ovariectomized female Wistar rats were randomly divided into 4 experimental groups: ovariectomized (Ov), Ov/Se, Ov/irradiated (Irr) and Ov/ Se/Irr. A bone defect was created on the tibia of all animals 40 days after ovariectomy. Two days after surgery, only the Ov/Se and Ov/Se/Irr rats received 0.8 mg Se/kg. Three days after surgery, only the Ov/Irr and Ov/Se/Irr rats received 10 Gy of x-rays on the lower limb region. The animals were euthanized at 7, 14, 21 and 28 days after surgery to assess the repair process, which was evaluated by analysis of trabecular bone number (Masson Trichrome) and birefringence analysis (Picrosirius). It was possible to observe a delay in the bone repair process in the ovariectomized/irradiated group and similarity between the ovariectomized, Ov/Se and Ov/Se/Irr groups. In conclusion, sodium selenite exerted a radioprotective effect in the bone repair of tibia of ovariectomized rats without toxicity.

The present study examined the dose-dependent effect of vitamin E in reversing bone loss in ovariectomized (Ovx) rats. Sprague-Dawley rats were either Sham-operated (Sham) or Ovx and fed control diet for 120 days to lose bone. Subsequently, rats were divided into 5 groups (n=12/group): Sham, Ovx-control, low dose (Ovx + 300 mg/kg diet; LD), medium dose (Ovx + 525 mg/kg diet; MD), and high dose (Ovx + 750 mg/kg diet; HD) of vitamin E and sacrificed after 100 days. Animals receiving MD and HD of vitamin E had increased serum alkaline phosphatase compared to the Ovx-control group. Bone histomorphometry analysis indicated a decrease in bone resorption as well as increased bone formation and mineralization in the Ovx groups supplemented with MD and HD of vitamin E. Microcomputed tomography findings indicated no effects of vitamin E on trabecular bone of fifth lumbar vertebrae. Animals receiving HD of vitamin E had enhanced fourth lumbar vertebra quality as evidenced by improved ultimate and yield load and stress when compared to Ovx-control group. These findings demonstrate that vitamin E improves bone quality, attenuates bone resorption, and enhances the rate of bone formation while being unable to restore bone density and trabecular bone structure.
