Objectives : We examined the effect of Jengjengamiyjin-tang, a traditional herbal formula, on the experimental pancreatitis induced by Dibutyltin Dichloride(DBTC). Methods : 15 mice were divided into 3 groups; the normal group and the control group which were administered water only after pancreatitis elicitation and the test group which were administered Jengjengamiyjin-tang for 7 days after pancreatitis elicitation. Results : In the activities of amylase, lipase and alkaline phosphatase in serum, the test group showed significant decrease compared with the control group after 21 days. In the common morphology and histochemical study, various injuries by hemorrhagic erosion were observed in the control group, while they were significantly decreased in the test group. In the immunohistochemical study, the manifestation of COX-1, 2, HSP27, HSP70, MAC387, Ki-67 decreased significantly in the 14th day in the test group, however, they increased in the 21st day more than the control group(p<0.05). Conclusion : According to the above results, it is supposed that Jengjengamiyjin-tang has anti-inflammatory effect on the experimentally induced pancreatitis and may be applicable to pancreatitis especially in the acute stage.

Yacon has been used in folk medicines as a medicinal tea for hypoglycemia treatment. In a recent study described herein, antioxidative, antibacterial, antifungal activities, and cell-protective functions of yacon leaves have been reported. To evaluate the effects on fibrosis on pancreatitis, the efficacy of 1% of yacon extract (YE) on dibutyltin dichloride (DBTC) (8 mg/kg)-induced pancreatitis in rats was examined. On the 21st day after the DBTC treatment, a large increase in collagen was observed in the pancreas in the DBTC-treatment group (DT). But this was noticeably decreased with YE. In relation to the expression of COX-2, there was no response or a very weak response in the pancreas of the control group (CON). However, in DT, strong expression of COX-2 was observed in the pancreas on the 14th day, and COX-2 was present in inflammatory cells in the pancreas of the DT, especially on the 21st day. The expression was decreased for YE compared with DT. A remarkable increase in TGF-${\beta}1$ expression was observed in inflammatory cells in the pancreas in DT on the 21st day, whereas the expression was not found in YE after 21 days. However, on the 21th day, TGF-${\beta}1$ expression was increased in acinar cells of YE compared with DT. VEGF expression was very similar to the expression of in the pancreas. These results suggest that YE has an inhibitory effect on DBTC-induced pancreatic fibrosis.
