To investigate the effect of ILGUAN-JEON on liver and gastrointestinal track. this experiment were performed and obtained results wewe as follows. 1. ILGUAN-JEON depressed the isolated intestine movement and showed anti- acethylcholine and barium chloride effect in mice. 2. ILGUAN-JEON showed anti- acethylcholine and barium chloride effect on isolated stomach in rats. 3. ILGUAN-JEON showed anti-ulcer effect in rats induced by indomethacin and pyrous cracking. 4. ILGUAN-JEON depressed the gastric lesion in rats induced by HCI-ethanol. 5. ILGUAN-JEON depressed the gastric juice and pepsin secretion, free acid and total acid level in Shay rats. 6. ILGUAN-JEON depressed the GOT and GPT level in rats induced by $CCl_4$ and d-galactosamine. From above results, think that ILGUAN-JEON can be applied to recover the liver and gastrointestinal function.
