Guh Sung Y.L.S.-95 is one of the polyacidic solution of which main component is acetic acid. We investigated the subchronic toxicity of the Guh Sung Y.L.S.-95 using SPF ICR mouse for 4 weeks. The Guh Sung Y.L.S.-95 was administered by gastric intubation, 1.0, 2.5, 5.0 g/kg body weight. The results are as follows: 1. There are no adverse effects on the clinical obserbation and body weight changes. Also, there are some significant changes in organ weight, but it was meaningless because of the absence of dose-response relationships. 2. In the hematological patterns of administered mouse, there are no significant changes between the treated groups. Also, there are no serological enzymatic changes in the treated mouse. In the 1.0 g/kg treated group, ASP activity was increased significnatly compared with control group. But, this level of activity was fall under the normal physiological range of control mouse. 3. Histopathological findings of the brain, liver, heart, spleen, kidneys, stomach, lung, testis, ovary, uterus and thymus were not observed in the treated mouse. From the above results, the Guh Sung Y.L.S.-95 has no toxicity upto the 5.0 g/kg/day of oral dose for 4 weeks.

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.
