Abstract

Guh Sung Y.L.S-95 (GS95) is a kind of polyacidic solution, which contains acetic acid as a main component. We investigated in the present study tile genetic toxicity of GS95 according to the standard operation procedure from Korean Institute of Toxicology. In the Salmonella typhimurium reverse mutation assay using TA1535, TA1537, TA98 and TA100, GS95 did not induce mutation up to $5,000{\mu}g/plate$. GS95 did not induce chromosome aberration in Chinese hamster lung fibroblast in the concentration range between 1.25 and 5 mg/mL. In the rodent micronucleus assay, the frequency of micronucleated polychromatic erythrocyte in GS95 treated mice were not increased up to 5,000 mg/kg compared to the vehicle treated mice. Taken all these data together, GS95 was proven to be nongenotoxic in the concentration ranges tested.

Guh Sung Y.L.S-95 (GS95)는 초산을 주성분으로 하는 목초액으로 본 연구에서는 GS95의 유전독성을 국립독성연구원의 표준작업지침서에 따라 수행하였다. Salmonella typhimurium TA1535, TA1537, TA98, TA100을 이용한 복귀돌연변이시험에서 GS95는 최고농도 $5,000{\mu}g/plate$까지 돌연변이 집락수를 유의적으로 증가시키지 않았다. Chinese hamster lung fibroblast를 이용한 염색체이상 시험에서 GS95는 1.25-5mg/mL의 농도범위까지 음성의 결과를 나타내었다. 또한 ICR mouse를 이용한 소핵시험에서 GS95는 최고농도 5,000mg/kg까지에서 소핵을 가진 다염성적혈구의 출현율이 음성대조군에 비해 유의한 차이를 나타내지 않았다. 이상의 연구결과에 따라 GS95는 상용량에서 유전독성을 유발하지 않을 것으로 사료된다.
