摘要

以10-10(4)Gy的剂量照射质膜胸腺细胞，每1 mg膜蛋白存在125和1125 μ mol Ca2+。测定了1-苯胺萘-8-磺酸钠的荧光和吡啶的聚合度。结果表明，钙对受辐射影响的质膜结构具有稳定作用。

[The effect of ionizing radiation and calcium on plasma membrane structure].

Plasma membrane thymocytes were irradiated with doses of 10-10(4) Gy in the presence of 125 and 1125 mu mol of Ca2+ per 1 mg of membrane proteins. Fluorescence of 1-anilinonaphthalene-8-sulphonate and the degree of pyren eximerization were determined. The data obtained indicate that calcium can exert a stabilizing effect on the plasma membrane structure affected by radiation.
