【摘要】目的:觀察金水寶膠囊對糖尿病勃起功能障礙大鼠血糖、糖化血紅蛋白、晚期糖基化終產物(AGEs)及血管緊張素Ⅱ(AngⅡ)的影響。方法:采用SD大鼠腹腔注射鏈脲佐菌素(STZ),造模后第3d、第1周、第2周斷尾取血檢測血糖,當血糖大于16.6 mmol/L時同時頸項皮膚松軟處注射阿樸嗎啡無勃起,提示糖尿病勃起功能障礙大鼠模型造模成功。將動物隨即分為金水寶高劑量治療組、金水寶中劑量治療組、金水寶低劑量治療組、陽性對照組、模型組各10只,各組間大鼠體重、血糖無顯著性差異。同時留10只作為空白對照組。給藥8周后測定大鼠血糖濃度、糖化血紅蛋白含量、AGEs及AngⅡ水平。結果:與模型組相比,金水寶高、中、低劑量治療組均能夠降低血糖、糖化血紅蛋白、AGEs及AngⅡ水平(P<0.01),但以金水寶高劑量組最顯著(P<0.01),其中血糖監測中,金水寶中、低劑量組治療組之間無意義,糖化血紅蛋白中,金水寶低劑量治療組與陽性對照組之間無意義。AGEs及AngⅡ水平的金水寶中、低劑量治療組之間無統計學意義(P>0.05)。結論:金水寶能有效協助降低血糖、糖化血紅蛋白、AGEs及AngⅡ水平,其中金水寶高劑量治療組療效最顯著,為該制劑臨床用于治療糖尿病勃起功能障礙提供了實驗理論依據。

【Abstract】Objectives: To observe the influence of Jinshuibao Capsule and melbine on blood glucose, GHb, AGEs and AngII levels in rats with diabetic erectile dysfunction. Methods: Rats were injected with intraperitoneal STZ to establish their DED model and randomly divided into five groups: control group, model group and Jinshuibao capsule high/ medium /low dose group. The fasting blood glucose concentration, glycated hemoglobin levels and advanced glycation end-products and angiotensin of rats were determined in 8 weeks later. Results: Compared with model group, Jinshuibao capsule high, medium and low dose group and melbine can decrease the AngII level (P< 0.01), the most significant in high dose group (P< 0.01). Medium and low dose group had no statistically significant difference in blood glucose, FPG and AGEs and AngII (P>0.05); low dose group and control group had no statistically significant difference in glycosylated hemoglobin (P>0.05). Conclusions: Jinshuibao Capsule can reduce blood glucose and glycated hemoglobin level, AGEs and AngII expression, especially used in high dose, which provides basis for clinical treatment of diabetic neuropathy.

糖尿病(diabetesmellitus, DM)是由遺傳、環境及其他多方面因素共同影響而引起的一系列以糖代謝紊亂為主要臨床表現的綜合征。目前我國糖尿病患者已有幾千萬,為全球糖尿病患者最多的國家。到目前為止無法根治,僅僅可以通過藥物、飲食、生活習慣等加以控制。糖尿病本身并不致命,但糖尿病引發的各種急慢性并發癥,往往影響了患者的工作及生活,甚至危及生命[1]。糖……
