Since the first deliberate repair of hiatal hernia by Wm. J. Mayo in 1911, counterless procedure have been performed to correct herniation of the stomach into the posterior mediastinum. Recently,we experienced 51 years old female patient with large paraesophageal hernia and complete intrathoracic stomach which combined with multiple gastric erosion with chronic blood loss. So gastric ulcer within a diaphragmatic hernia is a distinct physiophathologic and clinical entity that our patient suffered from severe anemia due to chronic blood loss. The hernia was repaired transabdominally including reduction of stomach, excision of sac, closure of defect, anterior gastropexy, and gastr6stomy. Because of absent gastroesophageal refiux, no another antireflux procedure was required and erosion was managed by H2 receptor blocker.

Objectives : This study was carried out to investigate the anti-ulcer effects of Pyeongwibunsoeum extract and Misoprostol on indomethacin-induced gastric mucosal lesions of mice. Methods : Experimental groups were classified into non-treated group, non-administered group, Misoprostol-administered group and Pyeongwibunsoeum-extract-administered group. This study examined the morphological change, distribution of mast cells and apoptic cells, PNA reaction, COX-1, BrdU, NF-B p50, COX-2, IL-2R-, and ICAM-1of gastric mucosa. Results : 1. The hemorrhagic erosion of gastric mucosa was reduced in the Misoprostol-administered and Pyeongwibunsoeum-extract-administered groups. 2. The Misoprostol-administered group and Pyeongwibunsoeum-extract-administered group showed positive reaction on the PNA distribution. 3. The distribution of apoptic cells, activity of NF-B p50, COX-2, IL-2R-, and ICAM-1 decreased in both the Misoprostol-administered group and Pyeongwibunsoeum-extract-administered group. 4. The Misoprostol-administered and Pyeongwibunsoeum-extract-administered groups showed increase on COX-1, BrdU. Conclusions : As the results indicate, hemorrhagic erosion of gastric mucosa were reduced in both the Misoprostol-administeredand Pyeongwibunsoeum-extract-administered groups, and severe inflammatory reaction of gastric mucosa was reduced. The effects on the Pyeongwibunsoeum-extract-administered group were superior to those on the Misoprostol-administered group. Pyeongwibunsoeum extract can be widely administered for gastric ulcer disease in clinical treatments.

The bark of Ulmus davidiana var. japonica(Ulmaceae) has been described in traditional books to have diuretic and laxative actions, to ameliorate edematous disease, and to be used in insomnia and gastointestinal disorders. Thus this study was carried out to elucidate some of the pharmacological activities of the plant extracts. The results obtained in tills experiment indicated that its methanol extract elicited remarkable inhibition of HCI.ethanol induced gastric lesion, Shay ulceration and gastric secretion. However, it showed no anti-inflammatory action. The acute toxicity of the extract was low, that is, the minimum lethal dose was more than 2000 mg/kg by oral administration in mice. The systematic fractionation of the methanol extract by hexane, ether, ethylacetate and butanol resulted in potent prevention of gastric erosion in butanol and water fractions.

This study was carried out to investigate the protective effects of GaMiHyangSaYukGunJaTang on gastric mucosal lesions caused by indomethacin in rats.The test group was injected with indomethacin after the oral administration of GaMiHyangSaYukGunJaTang, while the control group was injected only with indomethacin. The lipid peroxidation level increased considerably in the control group, but superoxide disnurtase(SOD), catalase and glutathione(GSH) levels remarkably decreased. The following effects induced by indomethacin were observed in the stomach of the control group; mucosa hemoIThagic infarct, mucosa cell necrosis, leukocyte appearance, mucosa hemorrhagic erosion and gastric pit disawearance. In the test group, lipid peroxides level was significantly reduced compared with the control group While SOD, catalase and GSH levels considerably increased. The following effects were also observed in the stomach of the test group; mucosa hemorrhagic infarct, mucosa cell necrosis, leukocyte appearance and mucosa hemorrhagic erosion occured far less and gastric pit disappearance was not observed at all. This results suggest that GaMiHyangSaYukGunJaTang is effective in the remedy of gastric mucosal lesions as GaMiHyangSaYukGunJaTang suppresses the production of the lipid peroxides and free radicals induced by indomethacin and activates SOD, catalase and GSH.

This study investigated the role of nitric oxide on the oxidative damage in gastric mucosa of rats which received ischemia/reperfusion and its relation to mucus. Nitric oxide synthesis modulators such as L-arginine and $N^G-nitro-L-arginine$ methyl ester, and sodium nitroprusside, a nitric oxide donor, were injected intraperitoneally to the rats 30 min prior to ischemia/reperfusion which was induced by clamping the celiac artery and the superior mesenteric artery for 30 min and reperfusion for 1 h. Lipid peroxide production, the contents of glutathione and mucus, and glutathione peroxidase activities of gastric mucosa were determined. Histological observation of gastric mucosa was performed by using hematoxylin-eosin staining and scanning electron microscopy. The result showed that ischemia/reperfusion increased lipid peroxide production and decreased the contents of glutathione and mucus as well as glutathione peroxidase activities of gastric mucosa. Ischemia/reperfusion induced gastric erosion and gross epithelial disruption of gastric mucosa. Pretreatment of L-arginine, a substrate for nitric oxide synthase, and sodium nitroprusside prevented ischemia/reperfusion-induced alterations of gastric mucosa. However, $N^G-nitro-$ L- arginine methyl ester, a nitric oxide synthase inhibitor, deteriorated oxidative damage induced by ischemia/reperfusion. In conclusion, nitric oxide has an antioxidant defensive role on gastric mucosa by maintaining mucus, glutathione, and glutathione peroxidase of gastric mucosa.
