A nonspecific immunostimulator $BARODON^{\circledR}$ was tested for mutagenicity using Ames Salmonella tester strains TA98, TA1 00, TA 102, TA 1535 and TA 1537 with or without metabolic activation (59 mix). None of the fresh species showed mutagenicity. In the reverse mutation test using Salmonella phimurium TA98, TA100, TA102, TA1535 and TA1537 did not increase the number of revertants at all doses tested (5, 2.5 or 1.25 mg/ml). Chromosome aberration test was carried out in Chinese hamster lung (CHL) cell line. The cells were treated with $BARODON^{\circledR}$ (1, 0.5 or 0.25 mg/ml), while positive control group was treated with Mitomycin C (0.1 mg/ml). The results show that there is no statistically significant difference between positive control and treatment groups. In mouse micronucleus test, there was significant increase in the ratio of micronucleated polychromatic erythrocyte (MNPCE) in the high dose group (10% $BARODON^{\circledR}$), while there is no significance between control and low (2.5% $BARODON^{\circledR}$) or middle (5% $BARODON^{\circledR}$ dose groups. Taken together, this results suggest that below 5% $BARODON^{\circledR}$ might not have mutagenic potential in vitro and vivo systems.

Two local irritation and skin sensitization studies of nonspecific immunostimulator, $BARODON^{\circledR}$ were carried out with New Zealand White rabbits and Hartley guinea pigs. In skin irritation test of male New Zealand White rabbits, body weights were not significantly changed and there were no responses after treatment for 24 or 72 hours and the Primary irritation index (P.1.1.) was '0'. And, in the eye irritation test, there were chemosis in some of rabbits. One of 3 rabbits in washing group was detected chemosis after 24 and 72 h following treatment and 2 of 6 rabbits in non-washing group were detected chemosis after 24h and 7 days following treatment. Therefore, total score is '4' after 24 h and '2' after 72 h following treatment by conforming article "some blood vessel are clearly hyperemic" . However evaluation value is non-irritant because M.O.I. (Mean ocular irritation index) score is below during the all experimental period and no significance through individuals and exposure time. In skin sensitization, the score of skin reaction was graded 1 with 0% sensitization rate. Taken together, these results indicate that $BARODON^{\circledR}$ may be non-irritant material. material.
