为观察人肝RNA对X射线诱发小白鼠初级精母细胞染色体畸变的影响，以昆明种雄性小鼠为模型，皮下注射不同剂量的人肝RNA，24h后进行1．5GyX射线全身照射，照后地和24h检测小鼠初级精母细胞染色体畸变，结果发现：1.接种不同剂量（625mp／kg、25．0、100．0mp／kg）人肝RNA后，小
To observe the effect of human liver RNA on chromosome aberrations induced by X-ray in primary spermatocytes of mice, different doses of human liver RNA were injected subcutaneously in Kunming male mice and irradiated with 1.5 Gy X-rays after 24h And 24h detection of primary spermatocyte chromosome aberrations in mice, the results showed that: 1. Inoculation of different doses (625mp / kg, 25.0,100.0mp / kg) of human liver RNA, small
