Tracheo-gastric fistula is a very rare late complication of total laryngopharyngoesophagectomy with gastric pull-up procedure. It usually occurs after transhiatal esophagectomy, but it has only rarely been reported after total laryngopharyngoesophagectomy with gastric pull-up procedure. Chronic irritation and gastric ulcer may be the cause of tracheogastric fistula. To prevent fistula formation, active management of gastric ulcer and avoidance of mucosal irritation are necessary. We report a case of a tracheogastric fistula which occurred two years after total laryngopharyngoesophagectomy with gastric pull-up procedure that maybe occurred by chronic irritation and gastric ulcer.

The effects of human epidermal growth factor(EGF) which was produced by recombinant DNA technique was investigated on gastric secretion, gastric lesion and ulcer models in rats. The EGF showed significant inhibition of secretion of gastric juice and total acid output, at 0.4mg/kg, id and also inhibited Shay ulceration at 0.4mg/kg, id in rats. The lesion induced by absolute ethanol was significantly reduced by oral administration of EGF at 0.4mg/kg. Likewise, EGF caused significant inhibition of indomethacin induced gastric ulcer at oral doses of 0.2 and 0.4mg/kg. The EGF produced dose-dependent inhibition of gastric ulcer induced by acidified aspirin, but showed no significant inhibition at oral doses of 0.1, 0.2 and 0.4mg/kg. The chronic gastric ulcer induced by injection of 20% acetic acid solution was significantly reduced by oral doses of 0.1 and 0.4mg/kg of EGF. Duodenal ulcer induced by mepirizole was dose-dependently inhibited by oral doses of 0.1, 0.2 and 0.4mg/kg of EGF. These data suggest that EGF possesses pronounced inhibitory action in gastric ulcer and duodenal ulcer of rats.

Based on the gross lesion, a survey of ulcer prevalence was carried out on pigs (3,161 heads) at a slaughterhouse in seoul from April to December in 1989. The pigs stomachs were observed anatomically and classified, according to the presence or absence of foreign bodies. Ulcer prevalence is usually classified according to size of pig farm, ages, and supplied month. The results in the studies were as follows, 1. Fundus followed the highest rate with 28.2%, esophagus with 24.5％ each of cardiac and pyloric part with 7.8% and 4.1％ in cases of gastric mucosa pathological studies examed total 3,161. In the acute ulcer prevalence, fundus follwed with 5.4%, esophagus with 2.6%, each of cardiac and pyloric part with 0.8% and 0.3%. When prevalent frequencies of fundus are compared with cardiac and pyloric part, they have meaning.(P <0.05). 2. In the survey pig of total 3,161, pathological changes of epithelium tissue foliowed 44.0%, erosion(11.5%), chronic ulcer(14.8%), acute ulcer(1.6%), scar formation (1.7%) and perforation (0.9%). 3. In general monthly prevalence rates of gastric lesion are higher in spring and fall than in summer. 4. In the size of pig farms, ulcer showed higher rate at professional farms than raising on the side. 5. When there are more fluid condition in stomach and they are old, the ulcer appeared for more. 6. Foreign bodies in stomach were sand, hairballs, and intestinal worms were detected (1%).

Gastritis and gastric ulcer were known to be induced by gastic acid, stress, ethanol, Helicobacter pylori and free radical, etc. This study was performed for the development of a new drug or nutraceutical from medicinal plants or natural products with anti-gastritis, anti-ulcerative and gastroprotective activities. The water extract of Scutellaria baicalensis was exhibited potent inhibition in HCl ethanol-induced gastric lesion, acetic acid-induced and Shay ulcers, indicating the effects on gastric lesion and ulcer in rats. The water extract of Scutellaria baicalensis significantly inhibited HCl ethanol-induced gastric lesions at the oral dose of 300, 500 mg/kg. In pylorus ligated rats, the treatments of the water extract from Scutellaria baicalensis showed decrease in the volume of gastric secretion and acid output and increase pH at oral dose of 300, 500 mg/kg. And significantly reduced acetic acid-induced ulcer at the oral dose of 500 mg/kg for 12 days. In this study, we have found that the water extract from Scutellaria baicalensis had significant improvement in acute gastritis and ulcer at the dose of 300, 500 mg/kg and in chronic gastritis and ulcer at the dose of 500 mg/kg. Also we evaluated the antibacterial activity against Helicobacter pylori treated with Scutellaria baicalensis. Scutellaria baicalensis had a equivalent antibacterial activity with ampicilin against H. pylori at the dose of $100\;{\mu}/ml$. In histological examination, the water extract of Scutellaria baicalensis drastically restored gastric damages induced by HCl ethanol solution, pylorus- ligature and acetic acid. Therefore, we may use the water extract from Scutellaria baicalensis as antigastritic and antiulcerative agent for the purpose of the improvement or treatment of gastritis and gastric ulcer.

In this study, we investigated the inhibitory activities on gastritis and gastric ulcer using liriodendrin which is a constituent isolated from Kalopanax pictus. To elucidate its abilities to prevent gastric injury, we measured the quantity of prostaglandin $E_2$ ($PGE_2$) as the protective factor, and we assessed inhibition of activities related to excessive gastric acid be notorious for aggressive factor and inhibition of Helicobacter pylori (H. pylori) colonization known as a cause of chronic gastritis, gastric ulcer, and gastric cancer. Liriodendrin exhibited higher $PGE_2$ level than rebamipide used as a positive control group at the dose of $500{\mu}M$. It was also exhibited acid-neutralizing capacity (10.3%) and $H^+/K^+$-ATPase inhibition of 42.6% ($500{\mu}M$). In pylorus-ligated rats, liriodendrin showed lower volume of gastric juice ($4.38{\pm}2.14ml$), slightly higher pH ($1.53{\pm}0.41$), and smaller total acid output ($0.47{\pm}0.3mEq/4hrs$) than the control group. Furthermore liriodendrin inhibited colonization of H. pylori effectively. In vivo test, liriodendrin significantly inhibited both of HCl/EtOH-induced gastritis (46.9 %) and indomethacin-induced gastric ulcer (46.1%). From these results, we suggest that liriodendrin could be utilized for the treatment and/or protection of gastritis and gastric ulcer.

Present study was performed for the development of a new supplementary product with gastroprotective effect. The preliminary screening were conducted for the effects of HCl-ethanol-induced gastric lesions in rats. Samples were aloe gel, active hexose correlated compound (AHCC) mentioned that have GI protective property and pulmuone healthy aloe gel (PHAG) that mixture of natural products from Pulmuone company. Aloe gel significantly inhibited HCl-ethanol-induced gastric lesions at the oral dose of 5 ml/kg. AHCC showed the strongest effectiveness at the oral dose of 1,200 mg/kg. PHAG also showed the significant effects at the oral dose of 10, 20 g/kg. In pylorus ligated rats, the treatments of aloe gel, AHCC and PHAG showed decrease in the volume of gastric secretion and acid output. And aloe gel, AHCC and PHAG significantly suppressed the aspirin-induced ulcer and chronic ulcer in pylorus ligated rats. The treatments of aloe gel and PHAG significantly reduced acetic acid-induced ulcer at the oral dose of 5 ml/kg and 10 g/kg for 12 days. In this study; we have found that PHAG had significant improvement in acute gastritis and ulcer at the dose of 20 g/kg and in chronic gastritis and ulcer at the dose of 10 g/kg. Also we evaluated the anti-bacterial activity against H. pylori treated with aloe gel, AHCC and PHAG. PHAG had a equivalent anti bacterial activity with ampicillin against H. pylori at the dose of 1 g/kg.
