摘要:

目的: 探讨与分析左卡尼汀对大鼠糖尿病肾病的保护作用。方法: 24只8周龄的雄性SD大鼠随机分为3组,每组8只大鼠。为对照组提供单次腹腔内生理盐水(10 mL/kg)注射,接着静脉注射生理盐水(1 mL/kg);为糖尿病肾病组提供单次腹腔内链脲霉素(65 mg/kg)注射,接着静脉注射生理盐水(1 mL/kg);对于实验组,则提供单次腹腔内链脲霉素(65 mg/kg)注射,接着静脉注射左卡尼汀(50 mg/kg),都为1次/d,持续14 d,记录实验后肾功能情况。结果: 实验组与糖尿病肾病组都造模成功,实验后实验组与对照组的体质量显著高于糖尿病肾病组(P<0.05),血肌酐与尿蛋白排泄量及IL-6、TNF-α含量都显著低于糖尿病肾病组,肾组织Bcl-2、Caspase-3表达量都显著低于糖尿病肾病组,实验组与对照组之间对比差异无统计学意义(P>0.05)。结论: 左卡尼汀在大鼠糖尿病肾病中的应用能有效发挥肾功能保护作用,抑制肾组织的Bcl-2、Caspase-3表达,促进大鼠体质量恢复正常。

Abstract:

AIM: To investigate and analysis the protective effects of L-carnitine on diabetic nephropathy in rats. METHODS: Twenty-four 8-week-old male SD rats were randomly divided into three groups of 8 rats each. The control group were received single intraperitoneal injection of normal saline (10 mL/kg), followed by intravenously injection of normal saline (1 mL/kg). The diabetic nephropathy group were received single intraperitoneal injection of streptozotocin (65 mg/kg), followed by intravenously injection of normal saline(1 mL/kg). The experimental group were received single intraperitoneal injection of streptozotocin (65 mg/kg), followed by intravenously injection of intravenous L-carnitine (50 mg/kg), 1 time/d for 14 d, and the renal function after the experiment were recorded.RESULTS:The models of diabetic nephropathy were successfully established both in the experimental group and the diabetic nephropathy group. After the experiment, the body weight of the experimental group and the control group were significantly higher than that of the diabetic nephropathy group (P<0.05). Serum creatinine and urinary protein excretion, IL-6 and TNF-α, Bcl-2 and Caspase-3 in renal tissue of the experimental group and the control group were significantly lower than those of diabetic nephropathy group (P<0.05). There was no significant difference between the experimental group and the control group (P>0.05).CONCLUSION: The application of L-carnitine in diabetic nephropathy can effectively protect renal function, inhibit the expression of Bcl-2 and Caspase-3 in kidney tissue, and promote the recovery of normal body weight.
