[Toxicity and side effects of artemisiae annuae CQ-189].

Abstract

OBJECTIVE To observe the effects of artemisiae annuae CQ-189 (AACQ-189) on proliferation of hNSC and HELF in vitro, and the main organ toxicity and the median lethal dose (LD50) of kunming mouse in vivo. The purpose is to approach that the toxicity and side effects of AACQ-189. METHOD Using techniques of the colorimetric 5-diphenyl tetrazolium bromide (MTT) to detect the effects of AACQ-189 on proliferation of hNSC, and to detect the number of HELF survival by using techniques of trypan blue exclusion. To detect LD50 by tail vein injection in kunming mouse and using histomorphology method to observe the mouse main organ damage by AACQ-189. RESULT AACQ-189 has low poisonous function on hNSC and HELF that our experimental concentration (3.125-12.5 mg x L(-1)) has already achieve an effective dose to inhibit the proliferation of Leukemia cells obviously. LD50 concentration of kunming mouse is 550 mg x kg(-1). Moreover, AACQ-189 has little effect to main organs at higher concentration. CONCLUSION AACQ-189 has low poisonous function, which is a natural anti-tumor drug and has a promising prospect for potential application. However we should do more research on its mechanism.
