雄性Wistar大鼠分别饲以低硒低VE、适硒低VE和适硒适VE3种半合成饲料,4周后每组处死4只大鼠,剩余大鼠半数从第5周起用20mg/(kg·d)串珠镰刀菌素(MF)灌胃,半数用去离子水灌胃对照,7周后,处死全部大鼠,测睾丸PHGPX活力及睾丸、血浆和RBC硒水平,GPX活力。结果表明:给毒前睾丸PHGPX活力与睾丸、血浆和RBC硒水平及GPX活力有很好的线性相关,但低硒时PHGPX并未出现象GPX那样明显的下降,表明在睾丸中PHGPX比GPX有更重要的生物学活性。给毒后睾丸PHGPX活力在3个处理组均出现明显降低,Se和VE并未显示出保护作用,说明PHGPX是新发现的MF的另一毒性作用点
Male Wistar rats were fed with semi-synthetic feed with low selenium, low VE, low selenium and low selenium, respectively. After 4 weeks, 4 rats were sacrificed in each group, and the remaining rats were treated with 20 mg / kg · D) Fusarium moniliforme (MF) administered intragastrically, and half of them were treated with deionized water. After 7 weeks, all the rats were sacrificed and testicular PHGPX activity and testicular, plasma and RBC selenium levels and GPX activity were measured. The results showed that there was a good linear correlation between PHGPX activity before testis and testicular, plasma and RBC selenium levels and GPX activity, but PHGPX did not decrease as obviously as GPX during low selenium test, indicating that PHGPX in testes was higher than GPX More important biological activity. The PHGPX activity in testis after administration showed a significant decrease in the three treatment groups, Se and VE did not show a protective effect, indicating that PHGPX is another virulence point of newly discovered MF
