用人工合成饲料控制硒、锰含量。分为四组:A 组常硒常锰,B 组低硒常锰,C 组常硒高锰,D 组低硒高锰,喂养 Wister 雄性大鼠8周,从中观察鼠全血中 GSH—Px 活性的动态:在喂合成饲料前,各组全血中 GSH—Px 活性无显著差异。经喂饲1周后直到第8周,四组间酶活性在各周均有显著差异。常硒两组(A、C)酶活性均高于低硒两组(B、D),有非常显著差异。常硒两组(A、C)GSH—Px 活性在前两周是随着大鼠的生长而逐渐升高,而低硒两组(B、D)GSH—Px 活性在前两周是随着大鼠的生长而进行性降低。结果表明:全血中 GSH—Px 活性变化主要和硒含量相关。但通过析因方差分析显示:在实验的前两周,GSH—Px 活性除硒因素的影响外还受锰因素或硒、锰交互作用的影响。
Using synthetic feed to control selenium and manganese content. Divided into four groups: A group Chang Chang Chang Chang, B group of low-selenium manganese, C group of high-selenium manganese, D group of low-selenium and high manganese, Wister male rats fed for 8 weeks, observed from rat whole blood GSH-Px Activity dynamics: Before feeding synthetic feed, GSH-Px activity in all groups showed no significant difference. After 1 week of feeding and up to the 8th week, there were significant differences among the four groups in the enzyme activities. The activities of (A, C) enzymes in both selenium and selenium groups were significantly higher than those in the low selenium group (B, D). There were significant differences between the two groups. The activity of GSH-Px in both groups (A, C) increased gradually with the growth of rats in the first two weeks, while the activities of GSH-Px in the two groups with low selenium (B, D) Rat growth is progressively reduced. The results showed that the changes of GSH-Px activity in whole blood were mainly related to selenium content. However, analysis of factorial analysis of variance showed that in the first two weeks of the experiment GSH-Px activity was affected by the interaction of manganese factors or selenium and manganese in addition to selenium.
