醫(yī)學免費論文:正糖鉗技術觀察降濁合劑對大鼠胰島素敏感性的影響
【摘要】 [目的]采用正糖鉗試驗觀察比較降濁合劑對Wistar大鼠胰島素敏感性的影響。[方法]雄性Wistar大鼠32只,隨機分成降濁合劑高劑量組、降濁合劑低劑量組、羅格列酮組、正常對照組各8只,各組灌予相應的藥物7天后,大鼠腹腔麻醉,觀察大鼠正糖鉗試驗穩(wěn)態(tài)下的血糖(BG)和葡萄糖輸注速率(GIR)。[結果]降濁合劑可明顯降低大鼠正糖鉗試驗穩(wěn)態(tài)下的血糖(BG),提高穩(wěn)態(tài)下的葡萄糖輸注速率(GIR)。[結論]降濁合劑能提高胰島素抵抗大鼠機體組織對外源性胰島素的敏感性。

Abstract:[Objective] To observe the effect of jiangzhuo Mixture(JZM)on insulin sensitivity in Wistar rats by using the glucose clamp technique.[Methods]32 male Wistars were randomly divided into normal control group,control group treated with rosiglitazone and two experimental groups treated with high or low dose JZM.After durations of 7 days with corresponding treatment by intragastric administration,the blood glucose(BG)in homeostasis and glucose infusion rate(GIR)of each group is observed by using the glucose clamp technique.[Results]JZM can decrease the blood glucose(BG)in homeostasis and increase glucose infusion rate(GIR)obviously.[Couclusion]JZM can improve the insulin sensitivity in insulinresistancerats醫(yī).學.全.在.線zxtf.net.cn.

中藥復方降濁合劑是根據(jù)我院國家級名老中醫(yī)、主任中醫(yī)師王暉多年臨床用藥經驗,由我院制劑室配置的純中藥制劑,功能為補氣升清降濁,該藥在臨床應用中對于治療2型糖尿病屬肥胖氣虛痰濁型有較好的療效[1]。本研究觀察了降濁合劑對胰島素鉗夾Wistar大鼠穩(wěn)態(tài)下的血糖(BG)和葡萄糖輸注速率(GIR)的影響,并與陽性對照藥—羅格列酮進行了比較。
