加味聚精食疗方对少、弱精子症大鼠EGF、EGFR睾丸内表达的影响

目的观察加味聚精食疗方对少、弱精子症大鼠表皮生长因子（EGF）、表皮生长因子受体（EGFR）睾丸内表达的影响。方法 60只3月龄雄性SD大鼠采取随机化法分为六组：G1组、G2组、G3组、G4组、G5组、G6组,每组10只。G1组蒸馏水灌胃52 d;其余五组予雷公藤多苷（GTW）灌胃26 d造模。造模结束后,G6组立即脱颈处死,以了解造模质量;G2组加味聚精食疗方灌胃;G3组枸橼酸他莫昔芬片灌胃;G4组五子衍宗片灌胃;G5组蒸馏水灌胃,以上均每天1次,连续26 d。治疗结束后CASA技术检测大鼠附睾精子质量;Envision两步法检测睾丸组织EGF、EGFR的表达。结果G6组附睾精子质量的各项指标均较G1组明显减低（P〈0.05）,显示造模成功。G2组附睾精子质量所有指标均明显优于G5、G6组（P〈0.05）。G2组附睾精子密度明显优于G3、G4组（P〈0.05）。G1、G2组附睾精子质量所有指标组间比较,差异无统计学意义（P〉0.05）。G1、G2组大鼠睾丸组织EGF、EGFR表达水平明显优于G5、G6组（P〈0.05）。结论加味聚精食疗方能显著上调大鼠睾丸间质细胞EGF、EGFR的表达水平,改善精子质量。

Impacts of Modified Jujing Dietetic Recipe on the Expressions of EGF and EGFR in the testis of the Rats with Oligospermatism and Athenospermia

Objective To observe the impacts of modified juying dietetic recipe on the expressions of epidermal growth factor(EGF)and epidermal growth factor receptor(EGFR)in the testis of the rat with oligospermatism and athenospermia.Methods 60 SD male rats of 3 months old were randomized into six groups,named G1 group,G2 group,G3 group,G4 group,G5 group and G6 group,10 rats in each one.In G1 group,the gastric infusion with distilled water was done for 52 days.In the rest five groups,tripterygium glucosides(GTW)was u...
