The rhizoma of Zingiber officinale has been used as antiemetic, expectorants, stomachache relieving drugs and digestive accelerators. From the observation of antigastritic action of the methanol extract of the rhizoma, it was fractionated with hexane, chloroform, ethyl acetate and butanol, followed by bioassay on antigastritic and antiulcerative activity. The hexane and the chloroform fraction reduced significantly HCl ethanol induced gastric lesion at the dose of 370 and 210 mg/kg, p.o., respectively. On the gastric ulceration and gastric secretion in pylorus-ligated rats, the hexane fraction decreased the volume of gastric secretion and acid output, and also increased pH at the dose of 370 mg/kg, i.d.. It showed considerable curative ratio of acetic acid induced ulcer without inhibition of indomethacin induced gastric lesion. The methanol extract showed low acute toxicity with minimum lethal dose of more than 3000 mg/kg, p.o. in mice. In conclusion, Zingiberis rhizoma exhibited antigastric and antiulcerative activity which might be attributable to inhibition of gastric secretion. It is revealed that the active component may be present in the hexane fraction.

Vagal damage and subsequent pyloric denervation inevitably occur during esophagectomy, potentially leading to delayed gastric emptying (DGE). The choice of an optimal pyloric procedure to overcome DGE is important, as such procedures can lead to prolonged surgery, shortening of the conduit, disruption of the blood supply, and gastric dumping/bile reflux. This study investigated various pyloric methods and analyzed comparative studies in order to determine the optimal pyloric procedure. Surgical procedures for the pylorus include pyloromyotomy, pyloroplasty, or digital fracture. Botulinum toxin injection, endoscopic balloon dilatation, and erythromycin are non-surgical procedures. The scope, technique, and effects of these procedures are changing due to advances in minimally invasive surgery and postoperative interventions. Some comparative studies have shown that pyloric procedures are helpful for DGE, while others have argued that it is difficult to reach an objective conclusion because of the variety of definitions of DGE and evaluation methods. In conclusion, recent advances in interventional technology and minimally invasive surgery have led to questions regarding the practice of pyloric procedures. However, many clinicians still perform them and they are at least somewhat effective. To provide guidance on the optimal pyloric procedure, DGE should first be defined clearly, and a large-scale study with an objective evaluation method will then be required.

Antiulcer effects of Artemisia herba extract (DA-9601) were evaluated in various types of experimental gastric ulcer induced in rats. And the effects of DA-9601 on mucus, basal and stimulated gastric acid secretion were also investigated in rats. DA-9601 (12.5∼400 mg/kg, p.o.) prevented the formation of gastric ulcers induced by 60% EtOH in 150 mM HC1, restraint water immersion stress, platelet activating factor (PAF), aspirin in 150 mM HCI with Pylorus-ligation and indomethacin. DA-9601 (4∼400 mg/kg, p.o.) significantly accelerated the healing rate of acetic acid-induced gastric ulcer and significantly stimulated mucus secretion in a dose-dependent manner. DA-9601 (20∼200 mg/kg, i.d.), however, did not inhibit basal gastric acid secretion in pylorus ligated rats and DA-9601 (200 mg/kg, i.d.) failed to influence histamine-, pentagastrin- and carbachol- stimulated gastric acid secretion. These results suggest that DA-9601 has inhibitory action on gastric lesion and ulceration through increasing mucus secretion in the stomach of rats without influencing basal and stimulated gastric acid secretion.

Objectives : This study was performed to investigate effect of evodiae fructus on acute reflux esophigitis rat induced by pylorus and forestomach ligation operation. Methods : Twenty-four laboratory rats were divided four groups and each group had six rats ; normal intact group, acute reflux esophagitis (RE) control group, two experiment RE group treated extract of evodiae fructus 600 mg/kg (EEF600) and 300 mg/kg (EEF300). All rats was fasted for 18 hr but free water, we induced RE by pylorus and forestomach ligation operation. Intact group and RE control group rats were orally administered a distilled water and two experiment groups were orally administed with EEF 600 mg/5ml/kg and 300 mg/5ml/kg. One hour after, rats were anesthetized, intact group was cut the abdomen open and sutured with 2.0 silk thread. RE control group and EEF group were cut the abdomen open, ligated pyloric canal and forestomach with 2.0 silk thread and sutured. Six hour after the operation, rats were sacrified, collected bloods in the abdominal vein, disectted a esophagus and stomach. The stomach was washed a 1 ml PBS and the esophagus was cut longitudinally and pictured a innter mucosa area to research damages in esophagus. Results : The esophagic tissue damage percentage of reflux esophagitis rat was increased compared to that of normal intact group. But esophagic damage percentage of EEF 600 were significantly decreased compared to that of RE control group. But there was no difference on gastric juice pH between control RE, alpha-tocopherol administration rat group and EEF administration rat group. In esophagus of RE control rat, gastric damage occurred severely and injury percentage of mucosa were increased, but EEF 600 mucous inflammatory damage percentage was significantly compared to that of RE control group. Proinflammatory cytokines such as TNF-alpha, IL-1beta and IL-6 in serum on RE control group were markedly grew than those of intact rat, those of vechicle group treated with EEF 600 and EEF 300 were remarkably decreased compared to production of proinflammatory cytokine of RE control group. In microscopic observation, intact group rat had no hyperemia, mucous injury and exclusion, ulcer and edema. But it could showed mucosa damages, submucosa edema and ulcer in RE control. However, administration of EEF 600 and EEF 300 made esophagus have less inflammation and injury by gastric acid. Conclusions : The results suggest that antiinflammatory Effect of EEF could attenuate the severity of reflux esophagitis and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.

Purpose: To evaluate the feasibility and safety of intracorporeal overlapping gastrogastrostomy between the proximal anterior wall and antrum posterior wall (PAAP; PAAP anastomosis) of the stomach in minimally invasive pylorus-preserving gastrectomy (PPG) for early gastric cancer (EGC). Materials and Methods: From December 2016 to December 2019, 17 patients underwent minimally invasive PPG with PAAP anastomosis for EGC in the high body and posterior wall of the stomach. Intraoperative gastroscopy was performed with the rotation maneuver during proximal transection. A longer antral cuff (>4-5 cm) was created for PAAP than for conventional PPG (≤3 cm) at the point where a safe distal margin and good vascular perfusion were secured. Because the posterior wall of the proximal remnant stomach was insufficient for intracorporeal anastomosis, the anterior wall was used to create an overlapping anastomosis with the posterior wall of the remnant antrum. The surgical and oncological outcomes were analyzed, and the stomach volume was measured in patients who completed the 6-month follow-up. The results were compared to those after conventional PPG (n=11 each). Results: PAAP anastomosis was successfully performed in 17 patients. The proximal and distal resection margins were 2.4±1.9 cm and 4.0±2.6 cm, respectively. No postoperative complications were observed during the 1-year follow-up esophagogastroduodenoscopy (n=10). The postoperative remnant stomach (n=11) was significantly larger with PAAP than with conventional PPG (225.6±118.3 vs. 99.1±63.2 mL; P=0.001). The stomach length from the anastomosis to the pylorus was 4.9±2.4 cm after PAAP. Conclusions: PAAP anastomosis is a feasible alternative for intracorporeal anastomosis in minimally invasive PPG for highly posteriorly located EGC.

The experimental study used in this paper was done to examine the clinical effects of Taeumchowetang for the gastric ulcer and the function of gastrointestinal tract using rats and mice which were administered orally the water extraction from Taeumchowetang. Then, the counter-action of the water extraction on the isolated ileum and gastric fundus, the inhibitory effects of pylorus-ligated ulcer and indomethacin-induced ulcer, the associations with gastric juice secretion, total acidity, pepsin output, the transportability in the small and large intestine, were studied with administering acetylcholine chloride and barium chloride. In addition, it was investigated whether the central nervous system related to pain control and sleeping time was influenced by Taeumchowetang. The following results have been obtained; 1. As resulting from injection of acetylcholine chloride and barium chloride into the isolated ileum of rats and mice, Taeumchowetang led to have an inhibitory effect on the muscle contraction of the ileum. Then, acetylcholine chloride was measured as lower effect than barium chloride 2. For the inhibitory effect on contraction for the gastric fundus strip in rats by either acetylcholine chloride or barium chloride, the one showed low inhibitory effect, on the other hand the other showed density-dependent effect. 3. The water extraction was given on the pylorus ligated ulcer with using two different administration groups of 1,300mg/kg and 2,600mg/kg, each result was measured as 22.9% and 36.5% for an ulcerous inhibitory effect (p<0.05). 4. According to the two administration groups, the preventive effect was tabulated 18.1% and 29.3% for indomethacin-induced ulcer (p<0.05, P<0.01). 5. For associations with gastric juice secretion, total acidity, pepsin output in the administration group 2,600mg/kg, Taeumchowetang was recognized as having an inhibitory effects related to suppressive actions involving gastric juice secretion(p<0.05), and free acidity(p<0.01), but there was no significant association with total acidity and pepsin output. 6. To know the transportability in the intestine, BaSO4 solution was used. The transportability of the small intestine in the administration group 2,600mg/kg was 22.2% which was statistically significant compared with the large intestine's transportability(P<0.01). 7. In the administration group 1,300mg/kg and 2,600mg/kg, analgesic effect with against acetic acid was measured as being 16.8% and 24.4% which was shown as statistically siginificant(p<0.01). 8. No statistically significant association between Taeumchowetang and sleeping time was found in both 1,300mg/kg and 2,600mg/kg by administering phenobarbital-Na. According to the results of this study, Taeumchowetang has agreed with the effects of literature review. Further more in this study, Taeumchowetang also has preventive effects on pylorus-ligated ulcer. Hence, Teaumchowetang can be significant effect such as both anti ulcer agent and increasing gastric activity for the patients who suffer from gastric ulcer.
