摘要: 目的: 对体外培育牛黄的诱变性进行研究。 方法: 采用Ames试验、小鼠骨髓嗜多染红细胞微核试验、人外周血淋巴细胞体外培养染色体畸变试验等方法进行检测。 结果: ①Ames试验在1 250、 5 000、 10 000 μg / 皿的浓度范围内,各浓度组MR值在加代谢活化剂S 9和不加代谢活化剂S 9两种情况时均未超过2;②微核试验在50、 150、 500 mg / kg 3个剂量水平,各剂量组的微核率均数及PCE / NCE比值与空白对照组比较均未见显著性差异(P>0.05);③人外周血淋巴细胞体外培养染色体畸变试验在样品浓度为1、 10、 100 μg / ml(不加代谢活化剂,-S 9)和1、 10 μg / ml(加代谢活化剂,+S 9)两种情况下,各处理组测得的细胞畸变率与空白对照组比较均无统计学意义(P>0.05)。 结论: 体外培育牛黄在所给剂量范围进行的3种诱变性试验结果均为阴性。

Abstract: Purpose: To study the mutagenicity of Cultured Calculus Bovis. Methods: The studies were conducted with Ames test, micronuclei test and in vitro chromosome aberration test on human lymphocyte. Results: ① The results of Ames test showed no mutagenic effects with the concentration ranged from 1 250 μg / plate to 10 000 μg / plate. ② In micronuclei test, the mice orally received 50, 150, 500 mg / kg respectively per day for 2 days, no mutagenic effects were observed; and no significant reduction was observed on PCE / NCE ratio, compared with that of the negative control group(P>0.05). ③ The in vitro chromosome aberration test on human lymphocyte showed a negative result with the sample concentration ranged from 1 μg / ml to 100 μg / ml. Conclusion: No mutagenicity was found with Cultured Calculus Bovis in this experimentation.
