To measure the serum succinyl trialanine p-nitroanilide hydrolytic activity as new index of liver function in workers exposed to organic solvents, this study conducted 114 workers in department of shoe-making of shoes factories. The results obtained from this study were as follows : 1. The mean values of serum GOT, GPT, ${\gamma}GT$ in whole workers were $22{\pm}12.32,\;20{\pm}9.05,\;28{\pm}21.35IU/l$, respectively and the mean value of serum STN hydrolytic activity was $0.08{\pm}0.05$. 2. The serum STN hydrolytic activity was significantly higher for male (p<0.05) and there was no difference among the groups of age. 3. There was no difference in the groups by working hours but significant difference in persons who worked over 3 years or were exposed to toluene over 100ppm (p<0.05). 4. The correlation of the exposed dose of toluene and serum GOT, GPT, ${\gamma}GT$ and serum STN hydrolytic activity were statistically significant (r=0.027-0.518). 5. The exposed dose of toluene was most explainable variable and statistically significant among the factors affecting serum STN hydrolytic activity (p<0.05).
