In order to study the effects of Jengjengamiyjintang on the duodenal ulcer induced by HCI-aspirin in rats, the changes of histological profiles, goblet cells(PAS-positive cells), and the distribution and frequency of cholecystokinin(CCK)-8 and serotonin-producing gastro-entero-endocrine cells were observed after oral administration of Jengjengamiyjintang. Histologically, very severe injury to duodenal epithelium were observed in control groups and theses injuries were increased with time intervals. But in the Jengjengamiyjintang administrated groups, no gross lesion of ulcer were demonstrated and histologically minor injury to the mucosal epithelium were observed. PAS-positive cells were increased in the Jengjengamiyjintang administrated groups compared to that of control groups. Severe degranulation of CCK-8- and serotonin-immunoreactive cells were observed in control groups but these phenomenon was seldom in the Jengjengamiyjintang administrated groups. Serotonin-immunoreactive cells were significantly decreased in control groups but increased in Jengjengamiyjintang administrated groups compared with control groups. According to these result, it is suggested that Jengjengamiyjintang would accelarat the healing of the duodenal ulcer but the functional mechanisms were unknown.
