摘要
【目的】研究一味中药复方制剂的安全性,为人体肿瘤临床治疗用药提供参考。【方法】本试验对复方制剂进行了经口急性毒性、最大耐受量及其28 d经口毒性方面的研究。经口急性毒性预试验对各组小鼠一次灌服剂量0.2、0.6、1.8、5.4、16.2 g/kg (bw)的提取液,最大耐受量试验提取液按1.25、1.00、0.80、0.64、0.51 g/mL的质量浓度、0.04 mL/g (bw)的灌胃量对各组小鼠24 h之内灌胃3次,对小鼠连续观察7 d;将40只小鼠随机分为高、中、低剂量组及对照组,连续28 d灌服等体积不同含量[15、7.5、3.75、0 g/kg (bw)]的复方制剂,测定小鼠的血液生理生化指标。【结果】急性毒性结果表明:该复方制剂粗提物经口LD50>5 g/kg(bw),小鼠对其最大耐受量达到150 g/kg (bw),最大耐受量为人用剂量的1 050倍;28 d经口毒性试验中各组小鼠体重、血液生理指标与对照组相比差异不显著(P>0.05)。血液生化指标仅中剂量组LDH与对照、低、高剂量组差异显著(P<0.05),GPT、GOT、Cr和BUN各指标无显著差异(P>0.05)。【结论】该复方制剂对小鼠无毒性作用,对血液生理生化部分指标无影响,临床使用安全。
[Purpose]To study the safety of a traditional Chinese medicine compound formulation, and to provide a reference for clinical treatment of human tumor.[Method]The acute toxicity, the maximum tolerated dose and the 28 d oral toxicity of the compound formulations were studied. The mice were given a dose of 0.2, 0.6, 1.8, 5.4, 16.2 g/kg (bw) at the same time for oral acute toxicity test. The maximum tolerated test extract with the concentrations of 1.25, 1.00, 0.80, 0.64, 0.51 g/mL 0.04 mL/g (bw) was administered orally to the mice in each group within 3 hours, and the mice were continuously observed for 7 days. Forty mice were randomly divided into high, medium, low and control dose group. In the control group, the compound preparations of different concentrations [15, 7.5, 3.75, 0 g/kg (bw)] were administered for 28 days, and the blood physiological and biochemical indexes of the mice were determined.[Result]The results of acute toxicity showed that the crude extract of the compound preparation had an oral tolerance of LD50>5 g/kg (bw), and the maximum tolerance of the mice was 150 g/kg (bw), and the maximum tolerated dose was 1 050 times of the human dose. The body weight and blood physiological indexes of the mice in each group were not significantly different (P>0.05). The blood biochemical parameters only showed significant difference between the LDH and the control, low and high dose groups (P<0.05), and there were no significant differences in GPT, GOT, Cr and BUN (P>0.05).[Conclusion]The compound preparation has no toxic effect, has no effect on blood physiological and biochemical indexes, and is safe for clinical use.
