Objective: Danguieumja-gagambang (DGEJGB), a traditional Korean prescription, has been used as therapeutics for allergic diseases such as atopic dermatitis (AD). In this study, we compared with regulatory Effect of Atopic Allergic Reaction by Prescriptions A and by Prescriptions B. Methods : To evaluate and compare the atopic allergic effectiveness of two prescription (A, B) of DGEJGB, the author investigated a possible effect of DGEJGB on mast cell-mediated allergic reaction, cytokine secretion and mRNA expression in vivo and in vitro. Results : Mast cells are a potent source of mediators that regulate the inflammatory response in allergic reaction. In mice orally administered A, B of DGEJGB ( 0.1, 0.1 and 1.0 g/kg) for 1 h, compound 48/80-induced ear swelling was significantly reduced. Significant reduced levels (P < 0.05). of tumor necrosis factor $(TNF)-{\alpha}$ was observed in the human mast cell line (HMC-1) with DGEJGB (A). IL-6 and IL-8 secretion were significantly inhibited by DGEJGB (A, B). In addition, $TNF-{\alpha}$ and IL-8 mRNA expression were reduced by DGEJGB (A) at the dose of 0.01 mg/ml without cell toxicity. Conclusions : These results suggest that DGEJGB (A) contributes to the treatment of atopic allergic reactions rather than DGEJGB (B), and that its action may be due to inhibition of cytokine secretion and mRNA expression HMC-1.

Objectives : This study was carried out to investigate the effects of Pyungjintang on indomethacin-induced gastric mucosal lesions of mire. Methods : Experimental mice were classified into not-treated group (NOR group), gastro-inflammation elicitated group (CON group), misoprostol-administered group after gastro-inflammation elicitation (MA group), and Pyungjintang-administered group after gastro-inflammation elicitation (PA group). This study examined the morphological change, distribution of mast cells, mucus surface cells, neutral mucus secreting cells, acid mucus secreting cells, PNA reaction, angiogenesis (MIP-2), COX-1, Hsp70, NF-kB p50, COX-2IL-12B, ICAM-1, BrdU and apoptotic cells of gastric mucosa. Results : 1. The scars of diapedesis, dilatation of right gastric artery and the hemorrhagic erosions of gastric mucosa were reduced in the MA and PA groups. 2. Gastric perforation was observed in the gastro-inflammation elicitated group, but not in the MA and PA groups. 3. The COX-1 positive cellsl, cell proliferation of gastric mucosa, neutral mucus secreting ce31s, acid mucus secreting cells and PNA positive reaction of surface mucus cells were increased in the MA and PA groups. 4. The distribution of apoptotic cells, mast cells, MIP-2, Hsp70, NF-kB p50, COX-2, IL-l2B and ICAM-1 were decreased in the MA and PA groups. Conclusions : Pyungjintang had excellent effects on indomethacin-induced gastric mucosal lesions in mice.
