Sodium arsenate and Paljin-Tang extract (PJT), a herbal restorative were treated p.o. 20 mg/kg and 500 mg/kg, respectively, and concurrently to rats, and examined the effects on the liver of rats. The values of protein, aniline hydroxylase (AH) and 2-thiobarbituric acid (TBA) were increased in arsenic-treated group.
