Purpose : This study was peformed to evaluate the effect of Kamijoaguiem(JGE) on the bone mass and its related factors. Methods : We used ovariectomized rat as an estrogen-deficient animal model. The model rats of osteoporosis showed a significant decrease in bone density, bone ash density, calcium content of femur bone. At the 7th day after operating ovariectomy, rats were administered with JGE per orally, and continued for 10 weeks. And osteoporosis related parameters were determined to investigate the effect of JGE. Results : Bone density, bone ash density, bone calcium, magnesium and phosphorus was decreased in osteoporotic rats. JGE improved the decreased bone density, bone ash density and the decreased bone magnesium, but JGE didn't improve the decreased bone calcium and phosphorus in osteoporotic rats. Osteocalcin in serum and hydroxy-proline excretion in urine were increased in osteoporotic rats. Their levels were decreased when JGE was administered. ALP activity in serum was increased in osteoporotic rats. JGE didn't induce any significant changes. JGE showed significant increase in serum calcium level, total protein level, albumin level, BUN level, serum LDH activity. JGE didn't show significant increase in serum T-cholesterol density, triglyceride density, HDL-cholesterol density. JGE didn't show significant increase in RBC number, hemoglobin level, platelet number, hematocrit level. JGE showed inhibitory effect on the degradation of bone-matrix in osteoporotic rats, in histological examination to Hematoxylin-eosin stain. Conclusion : JGE might improve bone density due to inhibition of bone resolution in osteoporotic rats. It suggest that JGE may be useful prescription in osteoporosis.

본 연구는 구기자와 구기엽 추출물이 난소를 절제한 흰쥐의 체중 증가, 골밀도, 에스트로겐 수용체의 발현에 미치는 영향을 밝히고자 시행하였다. 실험군은 흰쥐 24마리를 가장수술군(Sham군), 난소를 절제한 대조군(OVX군), 난소절제 후 구기자 추출액을 투여한 군(LCF군), 난소절제 후 구기엽 추출액을 투여한 군(LCL군)으로 구분하였다. 8주 후 난소를 절제한 OVX군($330{\pm}5.39g$), LCF군($315{\pm}2.99g$) 및 LCL군($318{\pm}2.06g$)의 체중은 Sham군($281{\pm}1.71g$)에 비하여 증가하였다. 혈청 osteocalcin 활성은 OVX군($107{\pm}3.52ng/mL$)에 비하여 LCF군($444.6{\pm}26.9ng/mL$)과 LCL군($407{\pm}18.9ng/mL$)에서 증가하였다. Alkaline phosphatase의 활성은 OVX군($95{\pm}2.9U/L$)에 비하여 LCF군($108{\pm}2.7U/L$)과 LCL군($407{\pm}18.9ng/mL$)에서 증가하였다. 8주 후 넙다리뼈를 실체현미경으로 관찰한 결과 뼈 기질밀도는 난소절제군에서 감소하였으나, 구기자와 구기엽을 추출액을 투여한 군에서는 뚜렷이 회복되었다. 에스트로겐 수용체의 mRNA 발현은 OVX군에서는 거의 발현되지 않았으나, LCF군과 LCL군에서 뚜렷이 증가하였다. 이상의 결과로 보아 구기자와 구기엽 물추출물이 난소절제에 의하여 유발된 흰쥐의 뼈 기질 회복 또는 손실 지연에 효과가 있다고 할 수 있을 것이다.

Purpose: This study was done to identify the effects of weight-bearing exercise(WBE) on bone metabolism. Method: WBE was performed for 12 weeks by healthy college women. Bone-related parameters were measured four times during this period by evaluating the immunoradiometric assay and enzyme immunoassay. Bone mineral densities(BMDs) were measured by dual energy x-ray absorptiometry before and after the WBE program. Data was analyzed using t-test, paired t-test, $x^2$-test, and repeated measures ANOVA. Result: Osteocalcin, a bone formation marker, increased more in the experimental group than in the control group based on the interaction between time and group(F=3.29 p=.024). Little difference between the two groups was found for the other parameters: urinary deoxypyridinoline, insulin-like growth factorI, parathormone, serum calcium, and serum phosphorus without showing any time interaction between the groups. The femoral trochanter BMD rose in the experimental group while that of the control group fell, showing a significant difference for BMD(t=3.06 p=.005). However, there was no significant difference between the two groups for changes in BMD of the forearm, lumbar spine, femoral neck, and femoral ward's triangle. Conclusion: These findings supported the WBE is beneficial for increasing bone formation in college women and long-term application is needed to substantiate the effects of WBE as a intervention in promotion of bone-health.

Clinical and preclinical studies have reported that Lactobacillus gasseri BNR17, a probiotic bacterial strain isolated from human breast milk, reduces body weight and white adipose tissue volume. In order to further explore the actions of L. gasseri BNR17, we investigated the anti-menopausal effects of L. gasseri BNR17 in an ovariectomized (OVX) rat model. The serum alanine aminotransferase levels of the rats in the OVX-BNR17 group were lower than those of the rats in the OVX-vehicle only (OVX-Veh) group. Upon administration of L. gasseri BNR17 after ovariectomy, calcitonin and Serotonin 2A levels increased significantly, whereas serum osteocalcin levels showed a decreasing tendency. Compared to the rats in the OVX-Veh group, those in the OVX-BNR17 group showed lower urine deoxypyridinoline levels, lower pain sensitivity, and improved vaginal cornification. Furthermore, L. gasseri BNR17 administration increased bone mineral density in the rats with OVX-induced femoral bone loss. These results suggest that L. gasseri BNR17 administration could alleviate menopausal symptoms, indicating that this bacterium could be a good functional probiotic for managing the health of older women.

The purpose of this study was to examine whether soybean protein isolate with rich isoflavones which was the same amount as used for earlier study prevents bone induced by ovarian hormone deficiency. Forty female Sprague-Dawley rats (body weight 210 $\pm$ 5 g) were divided into two groups, ovariectomy (OVX) and sham surgery groups, which were each randomly divided into two subgroups that were fed casein and soybean protein isolate with rich isoflavones (isoflavones 3_4 mg/g protein). The diets were fed for 9 weeks after operation. The results of this study indicate that body weight gain and food intake were higher in OVX groups than in SHAM groups regardless of diets. Weight gain were higher in soy isolate groups than in casein groups. Serum Ca concentration was lower in OVX rats than in SHAM rats when fed casein diet. Within the OVX groups, serum Ca concentration was higher in rats fed soy isolate diet than in rats fed casein diet. Serum ALP were higher in OVX groups than in SHAM groups. Within the OVX, soy isolate groups, indices of serum osteocalcin, were a trend for greater than those of the OVX casein group. Crosslink value were increased in ovariectomy groups. Spine BMD and femur BMD of ovariectomy groups were significantly lower than SHAM groups. However, soy isolate with rich isoflavones group in ovariectomy groups, spine BMC and femur BMC were significantly increased after 9 weeks. In conclusion, the soy protein with rich isoflavones was beneficial for bone in ovareiectomized rats and the results were similar to the findings of our previous study which showed a beneficial effect on bone in growing rats.

The use of biochemical markers of bone turnover may be particular interest in the investigation of bone disorders with osteoporosis. Serum osteocalcin(OC), total alkaline phosphatase and procollagen C, reflecting bone formation, and urinary pyridinium cross-links excretion, reflecting bone reabsorption have been measured in hyperthyroidism, postmenopause women, after testosterone supplementation, androgen, testosterone and estrogen deficiency, bone mineral density degree, age duration. Bone marks which is reflect to metabolic bone disorders are biochemical indices method to measure enzyme activity about bone formation, bone absorption and bone components in blood or urine. Bone metabolism biochemical marks are correlated with osteophorotic agents and also represent significantly different between bone mineral density and bone biochemical marks. Therefore if we develope and use bone metabolism marks which have higher sensitivity and specificity in bone formation and bone absorption, I think that these bone biochemical marks can have utility in the clinical application to predict osteoporosis risk group, bone loss, bone fracture and response degree to treatment of osteoporosis risk groups.
