The purpose of this study was to investigate the effect of three different mulberry cultivars extracts on inhibition of platelet aggregation and blood flow improvement. Four groups were surgically ovariectomized (OVX). The fifth group was sham operated. Sprague-Dawley strain female rats were randomly assigned to the following groups. sham-operated rats(Sham), ovariectomized control rats(OVX-Control), ovariectomized rats supplemented with 80% ethanol extracts from fruits of Tajikistan mulberry (OVX-TM), Korea mulberry (OVX-KM) and China mulbery (OVX-CM) at 200 mg/kg bw/d. The mulberry extracts were orally administrated at 1 ml per day. The body weights of OVX rats were significantly heavier than the sham-operated rats at all values (p<0.05). The serum triglyceride level was significantly decreased after supplemented with the CM and KM extracts. The serum HDL-cholesterol level in the OVX-KM group was significantly higher than that in the OVX-control group. The passage time of whole blood showed significant correlation with triglyceride but reverse correlation with HDL cholesterol. The ability of platelet aggregation of groups treated with mulberry extracts was less than OVX-control group. Taken these together, mulberry extracts may be used to possibly improve the quality of life in menopausal women.

This study was conducted to investigate the effects of $Sasa$ $quelpaertensis$ bamboo and green tea on plasma and liver lipids, platelet aggregation, and erythrocyte membrane Na channels in ovariectomized (OVX) rats. Thirty female rats were OVX, and ten female rats were sham-operated at the age of 6 weeks. The rats were divided into four groups at the age of 10 weeks and fed the experiment diets: sham-control, OVX-control, OVX-bamboo leaves (10%), or OVX-green tea leaves (10%) for four weeks. Final body weight increased significantly in the OVX groups compared with that in the sham-control, whereas body weight in the OVX-green tea group decreased significantly compared with that in the OVX-control ($P$ < 0.01). High density lipoprotein (HDL)-cholesterol level decreased in all OVX groups compared with that in the sham-control rats ($P$ < 0.05) but without a difference in plasma total cholesterol. Plasma triglycerides in the OVX-green tea group were significantly lower than those in the sham-control or OVX-control group ($P$ < 0.05). Liver triglycerides increased significantly in the OVX-control compared with those in the sham-control ($P$ < 0.01) but decreased significantly in the OVX-green tea group compared with those in the OVX-control or OVX-bamboo group ($P$ < 0.01). Platelet aggregation in both maximum and initial slope tended to be lower in all OVX rats compared with that in the sham-control rats but was not significantly different. Na-K ATPase tended to increase and Na-K cotransport tended to decrease following ovariectomy. Na-K ATPase decreased significantly in the OVX-green tea group compared with that in the OVX-control group ($P$ < 0.01), and Na-K cotransport increased significantly in the OVX-bamboo and OVX-green tea groups compared with that in the OVX-control ($P$ < 0.05). Femoral bone mineral density tended to be lower in OVX rats than that in the sham-control, whereas the green tea and bamboo leaves groups recovered bone density to some extent. The results show that ovariectomy caused an increase in body weight and liver triglycerides, and that green tea was effective for lowering body weight and triglycerides in OVX rats. Ovariectomy induced an increase in Na efflux via Na-K ATPase and a decrease in Na efflux via Na-K cotransport. Furthermore, consumption of green tea and bamboo leaves affected Na efflux channels, controlling electrolyte and body water balance.

The aim of this study was to determine the effects of body weight, organ weight, hematological values and biochemical parameters by estrogen on the ovariectomized (OVX) rats. The animals were divided into 4 groups. Intact group (n=10) received no treatment and operation. Sham group (n=10) received only sham operation and no treatment. OVX group (n=10) received operation and no treatment. OVX+E2(n=10) received operation and estrogen. The body weight of each group increased, but that of OVX+E2 group decreased. There were very significant differences (P<0.001) of body weights between OVX+E2 group and the other groups. Also, the wight of important organs such as heart, liver, spleen and kidney was measured. The heart weight was significantly lower(P<0.05) in the OVX+E2 group than the Intact group. The liver weight of the OVX+E2 group was significantly different in comparison with those of the other groups. On the other hand, there were no significantly differences in the organ weight of spleen and kidney between the OVX+E2 group and the other remaining groups. The hematological values of WBC, RBC, MeV, MCH and MCHC were not significantly different among the groups. The serum total protein and albumin decreased significantly in the OVX+E2 group as compared to those in the intact group. But, there were no significant differences in Ca, IP and Mg among the groups. We conclude that estrogen was significantly decreased the body weight in the ovariectomized rats. Our findings suggest that estrogen may influence the process of lipid packaging and absorption in the ovariectomized rats.

Background: Examination of the effects of deer antler, old antler, and antler glue on postmenopausal osteoporosis in an ovariectomized Sprague-Dawley rat model. Methods: The study involved 7 experimental groups; SHAM (sham-operated rats), OVX (ovariectomized rats), E2 (ovariectomized rats with estradiol $10{\mu}g/kg$ daily, orally), DA (ovariectomized rats with deer antler extract 5.83 mg/kg), OA (ovariectomized rats with old antler extract 3.8 mg/kg), low-AG (ovariectomized rats with low dose of antler glue powder 12.5 mg/kg), high-AG (ovariectomized rats with high dose of antler glue powder 37.5 mg/kg). After 6 weeks of treatment, body weight, blood calcium, phosphorus, estradiol, liver [alkaline phosphatase (ALP), aspartate transaminase (AST), alanine transaminase (ALT)] and kidney [blood urea nitrogen (BUN)/creatinine ratio] function, and femoral bone mineral density (BMD) were measured. Results: The body weights of DA, OA, low-AG, and high-AG groups did not significantly differ from OVX group. Blood estradiol levels were significantly increased in the DA, low-AG, and high-AG groups compared to the OVX group. Blood calcium, phosphorus, ALP, AST, and ALT levels and BUN/creatinine ratio did not show significant changes in the DA, OA, low-AG, and high-AG groups. BMDs of the femur, and femoral head and neck were significantly increased in the low-AG group. In the OA group, the BMD of the femoral head and neck was significantly increased. Conclusion: Treatment with deer antler, or antler glue for 6 weeks was effective for increasing estradiol and femoral BMD in ovariectomized rats, suggesting that this may be of therapeutic benefit for osteoporosis.

The purpose of this study was to investigate the effect of manganese (Mn) supplementation on bone status and calcium balance in ovariectomized rats according to the calcium intake levels. Total of 50 Sprague Dawley female rats (6 weeks) were divided into 5 groups and bred for 12 weeks: sham operated control group (SACa), OVX Ca deficiency group (OLCa) with Ca deficiency diet (0.1% Ca modified AIN-93N diet), OVX Ca deficiency & Mn supplement group (OLCaMn), OVX adequate Ca group (OACa; 0.5% Ca AIN-93N diet) and OVX adequate Ca & Mn supplement group (OACaMn). BMD (bone mineral density) of the femur was increased by Mn supplementation in OVX adequate Ca group. However, BMDs of spine, femur and tibia were lowered in OLCa compared to the OLCaMn group. Bone strength of tibia in OLCaMn group was significantly lower than OLCa group. Serum ALP (alkaline phosphatase) and CTx (C-telopeptide of collagen cross-links) levels were significantly higher in ovariectomized rats than those in the sham group, but they were not changed by Mn supplementation. Ca retention rate and Ca absorption rate did not differ among the experimental groups. Urinary Ca excretion was increased by Mn supplementation in Ca deficiency rats. In summary, Mn supplementation resulted in positive effects on bone mineral density ovariectomized rats with which intake adequate Ca. However, Mn supplementation on Ca deficiency ovariectomized rats resulted in decrement of BMO and bone strength by increasing Ca excretion. Therefore, it is encouraged to consider calcium intake levels in supplementation of manganese in order to prevent postmenopausal osteoporosis and to keep bone healthy.

It is controversial whether low calcium intake, commonly associated with osteoporosis, results in calcium accumulation in soft tissues. This study was conducted to investigate the effects of low calcium (Ca) and oxalate (ox) intake on soft-tissue Ca deposits and bone metabolism in ovariectomized (ovx) rats. Eight week old female Sprague-Dawley rats were ovariectomized and divided into four groups. The rats were fed experimental diets containing low (0.1%, w/w) or normal (0.5%, w/w) Ca with or without sodium oxalate (1%, w/w); Sham/NCa, Ovx/NCa, Ovx/LCa, Ovx/NCa-ox, Ovx/LCa-ox for 6 weeks. All ovx rats showed a remarkable increase in body and tissue weight, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, blood urea nitrogen, alkaline phosphatase, and decreases in weight, ash, and Ca contents, as well as bone breaking force compared to those in sham rats. Serum Ca concentration was not significantly affected by dietary Ca levels or ox intake. Kidney Ca, ox acid content, and microscopic Ca deposition increased remarkably in the Ovx/LCa-ox group compared to those in the other groups. Ca content in the spleen and aorta also increased significantly, but the weight contents, Ca, bone breaking force, and Ca and oxalic acid in feces decreased significantly in the Ovx/LCa-ox group. Serum parathyroid hormone levels were not significantly different among the groups. These results indicate that low Ca intake decreased bone mineral content and increased Ca deposits in soft tissues, which was aggravated by ox intake in ovx rats. Thus, high ox intake may result in a kidney disorder in patients with osteoporosis who eat a low Ca diet.

Osteoporosis is one of the major health problem affecting postmenopausal women. Estrogen deficiency results in an increase in bone turnover, lead to bone resorption and an increase risk of fracture. The aim of this study was to evaluate the effects of Capsosiphon fulvecense extract (SCF) on the collagen content of the connective tissues and alkaline phosphatase activity of serum in ovariectomized estrogen-deficient rats. Three groups were surgically ovariectomized (OVX). The fourth group was sham operated. Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with CsF at 50mg/kg body wt (OVX-CSF50) and ovariectomized rats supplemented with CsF at 200mg/kg body wt (OVX-CSF200). The Capsosiphon fulvecense extracts were orally administrated at 1mL per day. The ovariectomy caused a decreasing in the levels of collagen content in bone, cartilage, skin and lung tissues. However CSF groups, supplementation with Capsosiphon fulvecense extract, were increased the level of collagen content in bone, cartilage, skin and lung tissues than OVX-control group. Alkaline phosphatase activity also were increased and calcium levels were decreased than OVX-control on serum. These results suggest that Capsosiphon fulvecense supplementation prevents postmenopausal bone loss, thus it may be used possibly to improve the quality of life in menopausal women.
