   The rapeutic effect of invigorating kidney on postmenopausal osteoporosis in rats
  【Abstract】 AIM: To study the therapeutic effect of invigorating the kidney on postmenopausal osteoporosis in rats. METHODS: Thirtytwo healthy female SD rats were randomly separated into 4 groups: normal group, model group, western medicine group, kidneyinvigorating group, 8 rats in each group. The postmenopausal osteoporosis model was established in the latter 3 groups by ovariectomy. One week later, rats in western medicine group were drenched with 50 mg/L nilestriol, 5 mL/week, and with 5 mL isotonic sodium chloride in other time; ones in kidneyinvigorating group were drenched with traditional Chinese medicine 200 g/L for tonifying the kidney, 5 mL/d, equivalent volume and concentration of sodium chloride was drenched every day in the same time to normal group and model group. Eight weeks later, blood from all the rats was harvested by removing eyeball, and left femoral bone was also taken. Bone mineral density (BMD) in femoral bone was measured by DPXPlus, and serum levels of E2 was detected by ELISA. RESULTS: In model group compared with other groups, BMD: normal vs model (P<0.01); western medicine vs model (P<0.01); kidney invigorating vs model (P<0.01); E2: normal vs model (P<0.01); western medicine vs model (P<0.01); kidneyinvigorating vs model (P<0.01); normal vs western medicine (P<0.01); normal vs kidneyinvigorating (P<0.01). CONCLUSION: Invigorating the kidney with traditional Chinese medicine can increase BMD, serum E2 in ovariectomized rat models, thus exerting the therapeutic effect on postmenopausal osteoporosis.

  【摘要】 目的: 研究 補腎法對大鼠絕經後骨質疏鬆模型激素含量及骨密度等作用,揭示補腎法 治療 骨質疏鬆的機制. 方法 : 將健康雌性SD大鼠32隻,隨機分成4組:正常組、模型組、西藥組、補腎組,各8隻. 除正常組外對其他組大鼠進行摘卵巢手術製造絕經後大鼠模型(去勢後大鼠). 術後1 wk,西藥組灌服濃度為50 mg/L的尼爾雌醇,每隻灌服5 mL/wk,其他時間灌服等量生理鹽水;補腎組灌服濃度為200 g/L的補腎中藥,每隻灌服5 mL/d ;正常組和模型組每日同時灌服等量生理鹽水. 投藥8 wk 後進行摘眼球取血,取左側股骨. 採用雙能X線骨密度儀測量大鼠股骨骨密度(BMD),採用ELISA法測定血清雌二醇(E2)含量. 結果: 正常組、西藥組、補腎組與模型組相比,BMD和E2: P值均<0.01. E2: 正常vs西藥(P<0.01);正常vs中藥(P<0.01). 結論: 補腎法能夠增加去勢大鼠BMD、血清E2,從而對絕經後骨質疏鬆有治療作用.

  0引言
  骨質疏鬆症(osteoporosis, OP)是老年人多發病之一,其中,絕經後骨質疏鬆症(postmenopausal osteoporosis, PM0)是原發性骨質疏鬆症中最常見的一種,患病率為30%~50% . 其發病緩慢,常被人們忽視,有人稱之為無聲無息的流行病[1]. 近年來我們通過大量臨床實驗觀察,發現採用以腎為本的 理論 辨證論治收效甚好. 本實驗我們採用中醫補腎藥物,治療PMO大鼠模型,觀察其對大鼠骨密度(bone mineral density, BMD)、血清雌二醇(estradiol,E2)水平的 影響 .
  1材料和方法
  1.1材料清潔級健康雌性SD大鼠32隻,8月齡,體質量(180~270)g,(由第四軍醫大學動物實驗中心提供). 骨松康膠囊由仙靈脾、仙茅、制川烏、 制草烏、 當歸、川芎、巴戟天等藥味組成,每袋9 g(第四軍醫大學西京 醫院 藥劑科生產); 尼爾雌醇片,0.1 mg/片,(批號:國藥淮字H31021648,上海華聯製藥有限公司生產);大鼠血清E2的ELISA試劑盒(陝西寶航微生物工程有限責任公司提供). G680511 治療儀,( 中國 青島鑫升實業有限公司生產); 雙能X線骨密度儀DPXPlus ( Luna Corp . USA.).
  1.2方法健康雌性SD大鼠32隻隨機分4組:正常組、模型組、西藥組、中藥組,各8隻,各組大鼠分別編號,除正常組外對其他組大鼠進行摘卵巢手術製造去勢大鼠模型(Ovariectomized, OVX),用20 g/L的戊巴比妥鈉按40 mg/kg作腹腔內注射麻醉,俯臥位固定於大鼠夾板上,常規消毒, 於背部一側腰椎旁約1 cm 處,逐層切開皮膚、肌層,進入腹腔,切除卵巢,逐層縫合切口,同法處理對側. 傷口用青黴素粉外擦,以預防感染. 術後1 wk,西藥組灌服濃度為50 mg/L的尼爾雌醇(5 mg溶於100 mL蒸餾水中),每隻灌服5 mL/wk,其他時間灌服等量生理鹽水;中藥組灌服濃度為200 g/L的骨松康膠囊(18 g骨松康膠囊溶於90 mL蒸餾水中),每隻灌服5 mL/d;正常組和模型組每日同時灌服等量生理鹽水,每隻灌服5 mL/d. 其間,各組動物均正常飲食,自由飲水. 投藥8 wk後進行摘眼球取血,取左側股骨.
統計學處理: 組間比較採用SPSS 10.0 軟體進行方差 分析 以及LSDt檢驗.
