ICR 마우스를 이용한 소핵시험을 통한 TA 약침의 안전성 평가

초록

Objectives : TA, a polyherbal extract, typically is used for pharmacopuncture therapy on patients with traffic accident-related injuries and musculoskeletal diseases. This study was performed to evaluate the safety of the TA extract, using a micronucleus test. Methods : The dose range and sampling time were first established. An in vivo micronucleus test was then performed to determine the induction of micronuclei in mouse bone marrow cells after a single intramuscular administration of TA to 7-week-old ICR mice (0.2 ml/animal, at 24 hours post-dosing). Results : The incidence of micro-nucleated polychromatic erythrocytes (PCEs) in PCEs in the TA group was similar to that in the negative-control group, while that in the positive-control group was significantly greater. The positive- and negative-control groups did not differ in the ratio of PCEs to total erythrocytes. Conclusions : Our toxicity study indicates that the TA extract does not induce micronucleus formation in mouse bone marrow cells.
