Brush border enzyme activities in control rats of different ages were studied. Disaccharases, dipeptidases and alkaline phosphatase levels were similar in both age groups. When the rats were sacrificed at two different times of the day the activity was significantly lower in the morning than in the evening in both adult and young animals. No similar differences were observed in lysosomal activities. After irradiation the enzyme activities in both groups presented the same patterns although variations were more marked in adult animals. At 120 hrs the tendency to return to control levels appeared less evident in adult rats. Morphologic data confirmed these results.
研究了不同年龄对照大鼠的刷状缘酶活性。两个年龄组的双糖酶、二肽酶和碱性磷酸酶水平相似。当在一天中的两个不同时间处死大鼠时，成年和幼年动物的酶活性在早晨均显著低于晚上。溶酶体活性未观察到类似差异。照射后，两组的酶活性呈现相同模式，尽管成年动物的变化更为明显。在120小时时，成年大鼠恢复到对照水平的趋势似乎不太明显。形态学数据证实了这些结果。
