摘要: 目的:研究银杏叶片对单侧输尿管梗阻(UUO)大鼠肾脏的保护作用。方法:Wistar大鼠随机分为假手术组、UUO模型组、苯那普利组及银杏叶片组,于给药后2周和4周分别测定各组大鼠肾脏指数、左右肾重比、N-乙酰-β-D-氨基葡萄糖苷酶(NAG)酶活性、尿液尿素氮、尿肌酐、血尿素氮、血肌酐及24 h尿蛋白排泄量等指标。结果:给药后2周,银杏叶组大鼠NAG酶活性 [(18.0±5.4) U•L-1]、血尿素氮 [(7.3±1.3) mmol•L-1]、血肌酐 [(35.2±8.4) μmol•L-1] 及24 h尿蛋白排泄量 [(9.82±4.42) mg] 均明显低于模型组 (P<0.05);给药后4周,银杏叶片组大鼠NAG酶活性 [(10.3±4.1) U•L-1]、血尿素氮 [(8.7±0.9) mol•L-1]、血肌酐 [(44.2±6.7) μmol•L-1] 及24 h尿蛋白排泄量 [(10.17±8.42) mg]均较模型组明显降低 (P<0.05);给予银杏叶片能减轻UUO大鼠肾间质纤维化程度。结论:口服银杏叶片对UUO大鼠肾功能和结构具有明显保护作用。

Abstract: To investigate the protective effect of Ginkgo biloba (Gb) tablet on rat kidney following unilateral ureteral obstruction (UUO). MethodsWistar rats were divided into four groups: sham group, UUO model group, Gb tablet treatment group and benazapril treatment group (n=12). After Gb tablet was given to UUO rats for 2 and 4 weeks, all rats were sacrificed, the index of kidney, ratio of left and right kidney weight, the activity of urinary N-acetyl-beta-D-glucosaminidase (NAG), urea nitrogen in urine and serum, creatinine in urine and serum and the 24 h urinary protein excretion were detected, respectively. ResultsThe NAG activity [(18.0±5.4) U•L-1], serum urea nitrogen [(7.3±1.3) mmol•L-1], serum creatinine [(35.2±8.4) μmol•L-1] and the 24 h urinary protein excretion [(9.82±4.42) mg] in Gb tablet treatment group were decreased significantly compared with UUO model group (P<0.05) 2 weeks after administration. The NAG activity [(10.3±4.1) U•L-1], serum urea nitrogen [(8.7±0.9) mmol•L-1], serum creatinine [(44.2±6.7) μmol•L-1] and the 24 h urinary protein excretion [(10.17±8.42) mg] in Gb tablet treatment group were obviously lowered than those in UUO model group after treated with Gb for 4 weeks (P<0.05). Gb tablet could lighten the lesion of kidney in UUO rats. Conclusion Gb tablet has obviously protective effect on renal function and structure in UUO rats.
