ABSTRACT

AIM:

To investigate the protective effect of puerarin on testis in diabetic rats.

METHODS:

The male Sprague-Dawley rats were randomly divided into normal control group,diabetic group,high dose puerarin(160 mg/kg),middle dose puerarin(120 mg/kg),low dose puerarin(80 mg/kg)treatment groups and aminoguanidine(100 mg/kg)treatment group.Corresponding drugs were intraperitoneal injected once a day.The animals in normal control group and diabetic group were given equal propylene glycol.12 weeks later,the rats were sacrificed and their testes were collected.Testicular structure was observed under transmission electronic microscope(TEM).The contents of nitric oxide(NO),malondialdehyde(MDA)and the activity of nitric oxide synthase(NOS),inducible nitric oxide synthase(iNOS),superoxide dismutase(SOD),Ca2+-ATPase and Na+-K+-ATPase in testis homogenate were detected biochemically.The levels of endothelin-1(ET-1)and calcitonin gene-related peptide(CGRP)were also measured by radioimmunoassay.In addition,the mRNA expressions of eNOS,iNOS,CGRP,ET-1 and AR in testis tissues were determined by reverse transcription polymerase chain reaction(RT-PCR).

RESULTS:

The pathologic changes such as cytoplasmic inclusion of sertoli cell and obvious vacuoles between sertoli cells and basal membrane of the contorted seminiferous tubules were observed under TEM in diabetic group.The contents of NO and CGRP,the activities of SOD,Ca2+-ATPase,Na+-K+-ATPase as well as the mRNA expressions of eNOS and CGRP decreased significantly(P
