SU어혈약침의 복귀돌연변이시험을 이용한 유전독성평가

초록

SU-Eohyeol pharmacopuncture(SUEP) was developed by adding Cervi Pantotrichum Cornu to Jungsongouhyul pharmacopuncture. This genotoxicity evaluation was performed to evaluate the mutagenic potential of the test substance SUEP agent using histidine, which requires strains of Salmonella typhimurium (TA98, TA100, TA1535, TA1537), and tryptophan, which requires Escherichia coli (WP2uvrA) strain in the presence and absence of metabolic activation. According to the results of the dose range finding study conducted prior to the main study, the dose levels of the test substance in the main study were determined as 100, 50, 25, 12.5, 6.25%, and positive and negative controls were established. As a result of the main study, the mean number of revertant colonies compared to negative controls was less than 2-fold at all dose levels of SUEP in all strains with and without metabolic activation. In the positive control group, the mean number of revertant colonies for each strain was markedly increased by more than two times compared to the negative control group. Based on the result of this study, the test substance, SUEP did not show any indication of mutagenic potential under the conditions of this study.
