We examined the effects of Whadamcheongwha-tang(WDCWT) extract on the acetic-acid induced antigastric ulcer in rats. These experiments investigated the numerical changes of gastrin and histamine secreting cells of the gastric mucosa by immunohistochemical method, and the changes of mucin of gastric mucosa by PAS-AB stain methods after the oral administration of WDCWT extract(1.0ml/day) and omeprazole(0.2mg/day) for 1, 3 and 6 weeks. The result are as follows; 1. When WDCWT extract was administrated for 1, 3, 6 weeks, in result, gastrin secreting cells in gastric mucosa were increased compared to the control group. 2. When WDCWT extract was administrated for 1, 3, 6 weeks, in result, the density of immunoreactive gastrin cells was increased compare to the control group. 3. When WDCWT extract was administrated for 1, 3, 6 weeks, in results, the changs of mucosal thickness stained by PAS/PAS-AB was increased compared to the control group. 4. When WDCWT extract was administrated for 1, 3, 6 weeks, in results, the density of PAS stain was decreased compare to control group, but density of AB stain was increased compare to control group. The results suggest that WDCWT extract inhibits a gastric acid secretion in rat gastric mucosa, and is useful in the treatment of the hyperacidity and gastric ulcer.

To examine effects of Whadamcheongwha-tang(WDCWT) extract, the mice investigated the gastrin and histamine secreting cells of the stomach by immunohistochemical method, and the lymphocytes of the spleen and thymus by flow cytometry after the oral administration of WDCWT extract(0.2ml/day) and omeprazole (1mg/day) for 7, 14 and 21 days. The result are as follows; 1. When WDCWT extract was administrated for 7 days, in result, gastrin secreting cells were unchanged. When omeprazole was administrated for 7 and 14 days, gastrin secreting cells were slightly increased than that of normal control group. When WDCWT extract was administrated for 21 days, in result, gastrin secreting cells were significantly increased 1.9 times than that of normal control group. When omeprazole was administrated for 21 days, gastrin secreting cells were increased 1.96 times than that of normal control group. 2. When WDCWT extract and omeprazole were administrated for 7 days, in result, histamine secreting cells were unchanged. When WDCWT extract was administrated for 21 days, in result, histamine secreting cells were significantly increased 1.9 times more than that of normal control group. When omeprazole was administrated for 21 days, in result, histamine secreting cells were increased 2.1 times compared with normal control group. 3. When WDCWT extract administrated for 7, 14 and 21 days, in result, splenic Band T lymphocytes, especially T/sub H/ lymphocytes were significantly increased compared with normal control group, and thymic T/sub H/ lymphocytes were also increased in WDCWT administrated group for 14 days. The results suggest that WDCWT extract inhibit a gastric acid secretion in mice stomach, and is useful in the treatment of the hyperacidity and gastric ulcer.
