摘　　要：本文以低硒粮为基础饲料和基础饲料补0.25ppmSe喂养大鼠,观察饲料硒含量对~3H—尿苷参入胰腺RNA速率和对胰腺RNA含量的影响。发现补硒组大鼠胰腺RNA合成增多,RNA含量增高,且可防止由低硒粮引起的胰腺外分泌细胞萎缩和组织纤维化。此外’本文简要分析了硒在维持胰腺正常结构和功能中的作用。After rats were fed separately with selenium-low (Se: 0.021 ppm) and selenium-supplemented diet(Se: 0.250 ppm) for 12 weeks, the effects of selenium on RNA synthesis and RNA content were observed and compared by determination of UR—~3H incorporation into RNA in pancreas. The results indicated that selenium could prevent obstruction of RNA syntesies, reduction of RNA content and GSH-Px activity, increase of TBA value due to selenium-low diet, and protect the constuction and function of pancreatic tissue in rats.
