【摘要】 目的探讨合成化合物脂蛋白酯酶活化剂NO-1886对高糖高脂喂养小型猪肾脏蛋白激酶C表达的影响。方法广西巴马小型猪共15只,按体重随机分为3组,5只/组:正常对照组,喂正常猪饲料;高糖高脂组,喂高糖高脂饲料;加药组,喂加入1.0%NO-1886的高糖高脂饲料。动物分栏喂养,每日投食3次,日粮为体重的4%,自由饮水。实验期为5个月。实验前和实验过程中每月末分别抽取血样,葡萄糖氧化酶法检测空腹血糖;GPO-PAP酶法测定血浆三酰甘油;放射免疫法测血浆胰岛素。第5个月从左肾下极的相同部位取部分组织(包括皮质和髓质),HE染色以观察细胞显微结构,同时免疫组化染色;免疫组织化学方法和Western blot方法分别检测肾脏蛋白激酶C表达情况。结果使用NO-1886组的葡萄糖、胰岛素和三酰甘油水平显著下降;肾脏细胞显微结构结构基本正常;免疫组织化学方法和Western blot方法检测的结果同时说明NO-1886可以降低高糖高脂饮食所致巴马小型猪肾脏组织中蛋白激酶C的表达。结论NO-1886可以通过降低糖尿病肾病中的高血糖和高血脂,下调巴马小型猪肾脏组织中蛋白激酶C的表达。更多还原

【Abstract】 Objective To investigate the protective the effect of NO-1886 on the expression of protein kinase C in the kidneys of diabetic minipig model induced by high-sucrose and high-fat diet.Methods 15 Guangzhou minipigs aged 3 months were randomly divided into 3 groups of normal control,diabetes,diabbetes treatment,which were fed by basaldiet,high sucrose and high fat feed or with 1.0%No-1886 respectively.These minipigs were killed at the end of 5th month.Minipigs fed with high fat/high sucrose diet were treated with No-1886,and The fasting concentrations of plasma glucose,triglyceride,serum insulin and PKC were observed.Results High fat high sucrose feeding elevated fasting plasma glucose,trglyceride and serum insulin levels significantly.Supplement of No-1886 into high fat high sucrose diet induced a decrease in plasma glucose,triglyceride,insulin and PKC concentration compared with pigs fed with the sole high fat high sucrose diet.Conclusion No-1886 suppressed plasma glucose,triglyceride,insulin and PKC level.更多还原
