Objectives: Osteoporosis is one of the most common metabolic bone disorders in the menopausal stage, a disease signified by decrease of bone mass. The purpose of this study was to learn how Lycii Fructus influences SD rats with osteoporosis caused by the removal of the ovaries. Methods: After the removal of the ovaries from 24 female Sprague-Dawley rats, they were divided into a normal group, a control group, and a Lycii Fructus (25mg/100g) administration group. After 8 weeks, the rats were sacrificed and their weights, albumin, AST, ALT, ALP, total-cholesterol, triglyceride, P, Ca, T4, E2, weight of a femur, ash content of the tibia, and area and thickness of trabecular bone were measured. Results: Regarding the density of ALT, ALP, and estradiol from serum, the Lycii Fructus group was significantly decreased compared to the control group, and the density of phosphorous and calcium also decreased slightly. Moreover, albumin, triglyceride, and T4 showed an increasing propensity, but AST and total-cholesterol showed a decreasing propensity, but not significant. Regarding the variation of bone, femur weight and ash content of tibia, the Lycii Fructus group was increased compared to the control group but significance wasn't shown. The Lycii Fructus group increased significantly over the control group in area and thickness of trabecular bone and osteoclast number. Conclusions: From the results of the above study, Lycii Fructus should be effective for osteoporosis treatment and prevention.

연구 목적: 난소에서 분비되는 스테로이드 호르몬인 에스트로젠과 프로게스테론은 포유동물의 생식기관 발달과 정상적인 생식 기능, 수정과 배아의 착상에 중요한 역할을 한다. 특히 에스트로젠은 자궁내액을 내강으로 분비하여 자궁부종 기작에 중요한 역할을 한다. 자궁내액은 정자의 수정능력 획득과 착상전 배아의 발달에 매우 중요하다. Aquaporin (AQP)은 막관통 물수송 단백질로서 여러 조직에 넓게 분포되어 있으며, 세포간 또는 상피세포간 물의 이동에 중요한 역할을 한다. 본 연구에서는 생쥐 자궁에서 스테로이드 호르몬에 의해 조절되는 자궁내액의 이동에 AQP 유전자가 관여하는지를 알아보았다. 연구 재료 및 방법: 난소 절제술을 시행한 생쥐에 스테로이드 호르몬을 피하주사하고 6, 12, 24시간 간격으로 자궁조직을 적출하였다. 대조군은 sesame oil만을 주사한 후 6시간째에 수획한 자궁조직을 사용하였으며, 실험군은 시간대별과 스테로이드 처리별로 채취한 자궁조직에서 역전사중합효소반응을 수행하였다. 역전사중합효소반응을 통해 막관통 단백질인 AQP-4, -5, -8 mRNA의 발현양상을 살펴보았다. 또한 mRNA의 위치를 살펴보기 위해 laser microdissection을 이용하여 RT-PCR을 수행하였다. 마지막으로 자궁조직내에서의 단백질 발현 부위를 관찰하기 위해 면역조직화학염색을 실시하였다. 결 과: AQP-4, -5, -8 mRNA은 프로게스테론을 처리한 군보다 에스트로젠을 처리한 군에서 많이 발현되었으며, 에스트로젠을 주사한 지 6시간째 발현정도를 대조군과 비교할 때 AQP-4, -5, -8 mRNA가 각각 7.9배, 2.8배, 3.8배로 나타났다. AQP-4, -5, -8 mRNA는 간충조직보다 자궁내 상피조직에서 스테로이드 호르몬의 영향을 받아 발현양상의 차이가 나타났으며, 주로 에스트로젠의 영향을 받아 발현이 증가하였다. AQP-4 단백질은 에스트로젠을 24시간 처리한 후 프로게스테론을 처리한 군의 자궁내 상피조직에서 많이 발현되었으며, AQP-5와 -8 단백질은 에스트로젠을 처리한 군의 자궁내 상피조직에서 발현이 증가하였다. 결 론: 이상의 결과를 통해 AQP-4, -5, -8은 주로 에스트로젠에 의해 자궁내 상피세포에서 발현이 증가되는 것으로 보아 에스트로젠의 영향하에 일어나는 자궁내액의 이동으로 인한 자궁부종기작에 이동통로로서 관여하는 것으로 사료된다.

Theosteoporosis, which is occurred after menopause, is a kind of metabolic bone disorder. It develops when the bone mass begins to decrease radically and its main symptoms are the bone fracture and the height-shortening. This thesis aims at what effects the Phlomis umbrosa will have for the prevention of the osteoporosis in the SD-rat that is caused by the ovariectomy. The 24 female white rats, after their ovaries are removed, were divided into the Normals, the Control group, Phlomis umbrosa Administrated group. After then, for 8 weeks, D.W to the normals and the control, and the Phlomis umbrosa(46 mg/100 g) to the Phlomis umbrosa group were given in the mouths of them. After 8 weeks the rats were sacrificed. And the weight, albumin, AST, ALT, total-cholesterol, triglyceride, P, Ca, T4, estradiol, the weight of the femur, the amount of tibia ash, the area of trabecular bone, the thickness of trabecular bone were measured. The serum analysis shows that the total cholesterol of the Phlomis umbrosa Administrated group reduced remarkably, compared to that of the control group. AST, ALT, ALP, T4 of Phlomis umbrosa group were decreased, but not in distinct measure. Estradiol of Phlomis umbrosa group increased substantially compared to that of the control group, but albumin, triglyceride, Phosphorous, calcium of the group showed the tendency to increase, but not so remarkably. The histological observation shows that the area and the thickness of (trabecular bone), the number of osteoclast of the Phlomis umbrosa groups increased significantly compared to those of the control group. Conclusions: The above experiment shows that Phlomis umbrosa has the prevention effect by supplying estradiol.

Purpose : This study was carried out to investigate the effects of Gagamdokhwalgisang-Tang on the morphometric changes of femur, and on the hormones and cytokines associated with bone metabolism in overiectomized rats. Methods : Twenty-four female Sprague-Dawley rats were divided into sham operated group(normal) ovariectomized group(control), and treated with extract of GD group(treated). Each group was evaluated the changes of body weight at 0, 3, 6, 8 weeks after ovariectomy. Morphometric analysis(femur weight, femur/body weight ratio, femur ash weight femur ash/body weight ratio cross sectional area of compact bone and concellous bone of femur) and histopathological examination were performed at 8 weeks after ovariectomy. Estrogen, Alkaline Phosphatase(ALP) and cytokine(Tumor necrosis $factor-{\alpha}$, $Interleukin-l{\beta}$, Inerleukin-6) assay were performed at 8 weeks after ovariectomy. Results : 1. The body weight of control and treated group was significantly increased(p<<0.001) compared with the normal group at 8 weeks. 2. The femur weight and femur/body weight ratio of treated group were significantly increased(p<<0.05, p<<0.01) compared with the control group at 8 weeks. 3. The femur ash weight showed no significantly different changes, but femur ash/body weight ratio of treated group was significantly increased(p<<0.05) compared with the control group at 8 weeks. 4. In the cross sectional area of cancellous bone of femoral body, the treated group was significantly increased(p<<0.001) compared with the control group at 8 weeks. 5. The serum estrogen level of treated group showed no significantly different changes compared with the control group at 8 weeks. 6. The serum ALP activity of treated group was significantly decreased(p<<0.01) compared with the control group at 8 weeks. 7. The serum Tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ level of treated group was significantly decreased(p<<0.05) compared with the control group at 8 weeks. 8. The serum $Interleukin-l{\beta}(IL-1{\beta})$ level of treated group was significantly decreased(n<<0.001) compared with the control group at 8 weeks. 9. The serum Interleukin-6(IL-6) level of treated group was significantly decreased(P<<0.01)compared with the control group at 8 weeks. Conclusion : These results indicate that GD inhibits bone resorption in ovariectomized rats. And the major inhibitory mechanism may be related to the inhibitory effects of GD on the secretion of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 in the pathogenesis of osteoporosis in estrogen deficient rats.

Objectives Osteoporosis is a common disease in adults with prevalence rate of more than 40%, and occurs more to female than to male. The purpose of this study is to identify the effect of Bia-hwan ($F{\acute{e}}i{\acute{e}}r$-$w{\acute{a}}n$) on the osteoporosis of ovariectomized rats. Methods 24 female rats were randomly assigned to a SHAM group, a control group, and a BAH group. Ovaries of the control group and the BAH group were extracted. After than, general animal feed were given to the SHAM group and the control group, animal feed contained BAH were given to the BAH group through mouths of them. After 8 weeks, rats were sacrificed and their weight, calcium, phosphorus, estradiol, total-cholesterol, triglyceride, ALP, albumin, AST, ALT, the weight of femur and tibia ash per body ratio, both area and thickness of trabecular bone, the area of osteoblast and the number of osteoclast were measured. Results The level of calcium, phosphorus, AST in the serum of the BAH group increased significantly compared to the control group. There was no significant difference between the control group and the BAH group in the level of estradiol, total-cholesterol, triglyceride, ALP, albumin, and ALT in the serum. There was no significant difference between the control group and the BAH group in the weight of femur and tibia ash per body ratio. The thickness of trabecular of the BAH group increased significantly compared to the control group, but there was no significant difference in the trabecular area. The area of osteoblast and the number of osteoclast of the BAH group decreased significantly compared to the control group. Conclusions From the results of the above study, oral intake of BAH can inhibit the decrease of calcium, phosphorus in blood and prevent the thinning process of the trabecular by suppressing activation of osteoclast. Thus, BAH may have effects on the treatment and prevention of osteoporosis.

연구목적: 스테로이드 계통의 에스트로겐 호르몬은 막 수용체와 결합하고 DNA에 부착되어, 자궁조직에서 발현되는 많은 유전자들의 발현 양상을 조절하는 것으로 알려져 있다. 본 연구에서는 난소를 제거한 생쥐 모델을 이용하여 에스트로겐에 의해 조절되는 전사 관련 유전자(transcription factor)들을 동정하고, early up-regulation gene으로 확인된 Fos related antigen (Fra1과 Fra2) 유전자의 발현 양상을 RT-PCR과 면역염색방법으로 살펴보았다. 연구재료 및 방법: 난소 절제술을 시행한 생쥐에 에스트로겐을 피하주사하고 2, 4, 6, 12시간 간격으로 자궁조직을 적출하였다. 대조군으로는 sesame oil만을 주사한 후 2시간째에 수획한 자궁조직을 사용하였으며, 시간대별로 채취한 자궁조직(n=4)에서 RT-PCR을 수행하였다. RT-PCR을 통해 early response gene으로 확인된 Fra1과 Fra2에 대한 에스트로겐의 영향을 살펴보기 위해 estrogen receptor antagonist인 ICI 182, 780을 주사하여 유전자 발현 양상의 변화를 살펴보았다. 또한, 자궁조직내에서의 단백질 발현 부위를 관찰하기 위해 면역조직화학염색을 실시하였다. 결 과: 생쥐 자궁조직에서 에스트로겐에 의해 발현 양상의 변화가 확인된 유전자는 early up-regulation genes (CREB2, Fra-1, 2, GATA5), late up-regulation gene (E2F1), no response genes (CREB1, ATF1, GLI3, E2F3), down-regulation genes (GLI2, E2F5, GATA-2, 3, 6) 등으로 구분할 수 있었다. 그 중 early up-regulation genes에 해당하는 Fra1과 Fra2 유전자는 ICI 182, 780에 의해 그 발현이 유의하게 감소되는 것을 확인하였다(p < 0.01). 이들 단백질은 생쥐 자궁조직의 상피세포층, 기질층, 근육층에서 고루 발현되었으며, 특히 근육층에서 강한 염색정도를 관찰할 수 있었다. 결 론: 이상의 결과를 통해 Fra1과 Fra2 유전자의 발현은 에스트로겐에 의해 조절됨을 알 수 있었으며, 이들의 강한 발현이 자궁조직의 근육층에서 관찰되어 이들의 기능에 대한 연구가 필요할 것으로 생각된다.
