摘要

在12.9 cGy/d的剂量率下，大鼠肺组织质膜腺苷酸环化酶(AC)活性发生了不同的相变。将AC基础活性与前期报道的类似辐射条件下鸟氨酸脱羧酶活性变化数据进行比较，结果显示出单向变化，表明camp依赖性过程可能参与了鸟氨酸脱羧酶的辐射修饰。

[Effects of chronic gamma irradiation on the activity of adenylate cyclase in rat lung tissue].

Different phase changes were observed in adenylate cyclase (AC) activity of pulmonary tissue plasma membranes under chronic gamma-irradiation of rats at a dose-rate of 12.9 cGy/day. Comparison of AC basal activity with the data reported earlier on changes in ornithine decarboxylase activity under similar radiation conditions showed unidirectional changes which indicated that cAMP-dependent processes were possibly involved in radiation modification of ornithine decarboxylase.
