Because Lonicerae Flos has effects of antiinflammatory and antioxidant, we studied an effect of Lonicerae Flos on reflux esophagitis (RE) through those effects. Rats were treated with three different dosages of LF (500, 250 and 125 mg/kg) orally for 14 days before pylorus and forestomach ligation. Six hrs after pylorus and forestomach ligation, we dissected a stomach and examined a stomach volume, gastric acid output, pepsin release in the stomach, total hexose, sialic acid in stomach tissue and histamine contents of sera. The results were compared with an ${\alpha}$-tocopherol (once orally, 1hr before operation, 30 mg/kg) treated group in which the effects on RE were already confirmed. Lonicerae Flos extract (LE) reduced gastric volumes compared to RE control. This indicate that LE protect a stomach mucosa by depressing of gastric acid release and corresponse with a reducing histamine content of serum. And LE decreasd a volume of pepsin in stomach compraed to RE control, LE increased contents of total hexose and sialic acid based on esophageal and gastric mucus. This indicated that an increased mucus by LE protected inflammation of esophagus mucosa and gastric mucosa induced by gastric acid. So, LE suppressed a gasric acid by decreasing a pepsin release in stomach, suppressed an injury of esophagus inducted by gastric acid with increasing esophageal mucus and a minimum dose of LE to RE was 250 mg/kg. The results suggest that antioxidant effects of LF could attenuate the severity of reflux esophagitis and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.

Changes in gastrointestinal tissue blood volume induced by variations of venous pressure between 6 and 40 mmHg were studied in 32 rabbits. Venous pressure lowering was produced by withdrawal of appropriate volume of blood and venous pressure elevation was obtained by partial occlusion of intra-thoracic vena cava inferior. Estimation of regional tissue blood volume was performed by means of regional distribution of injected $Cr^{51}-labeled$ red blood cells. The following results were obtained. 1. At the normal control venous pressure value of 18 mmHg, spleen showed the highest value of tissue blood volume expressed on weight basis, namely, $111{\mu}l/gm$, Liver tissue blood volume was $95\;{\mu}l/gm$, small intestine 24 and stomach $21\;{\mu}l/gm$, respectively. 2. Linear relationships were observed between venous pressure change and gastrointestinal tissue blood volume. The coefficients of correlation were: in spleen r=0.723; in liver r=0.791; in stomach r=0.704, respectively. In small intestine the relationship was less clear and r=0.358. Tissue blood volume of extrabdominal tissue, such as M. gastrocnemius was not influenced by venous pressure change. 3. The highest change in tissue blood volume expressed on weight basis was observed in spleen. The liver tissue showed the next highest change. Change in total tissue blood volume, however, was greatest in liver and next greatest in small intestine. This was interpreted by the fact that total weight of these two organs was much greater than that of spleen. 4. The mechanism that the change in tissue blood volume lies in the venous system which has a great compliance was discussed.

This study was performed to evaluate antiulcer effects of traditional folk medicines such as heat-treated acumen, halloysitum rubrum and os sepiae against stomach ulcer induced by acetic acid in Sprague-Dawley rats. Various pharmacological parameters were utilized to compare the antiulcer effects of aforementioned drugs based on the size of ulcer lesion, pepsin activity, free and total acidity, gastric secretory volume, and 5-HT (hydxoytrytamine) content. All folk medicines and ranitidine as control drus were shown to decrease ulcer lesion size after 5-day treatments, with the order of halloysitum rubrum, os sepiae, heat-treated acumen and ranitidine. All treated drugs except os sepiae inhibited the gastric volume as compared with that in the control group. Ranitidine most significantly inhibited the gastric volume. All the experimented drugs in this study lowered the gastric acidity. Halloysitum rubrum decreased it most remarkably, followed by ranitidine, os sepiae and heat-treated alumen after 5-day treatments. All used drugs alleviated the pepsin activity as compared with the control group, os sepiae being the highest then halloysitum rubrum, heat-treated alumen and ranitidine in turn. Heat-treated alumen and halloysitum rubrum showed mucin production to the great extent, and ranitidine had slight increasing effect thereon. At the end of observation period, all drugs except ranitidine increased 5-HT contents as compared to the normal group. From the above results, we could confirm the folk medicines such as heat-treated alumen, halloysitum rubrum and os sepiae have not only remarkable antiulcer effects but also preventing effects for the stomach ulcer recurrence, which suggest the experimented folk medicines could be developed as new antiulcer agents.

An experimental study was carried out to make a comparison between tube voltage and density of barium sulphate in the stomach radiography. The results were summarized as follows: 1. The percentage of density on concentrations of barium sulphate as contrast media could not show in differences with changes of voltages applied X-ray tube. 2. The changes of density visualized on X-ray film mainly depend upon with thickness of stomach filled barium sulphate than the ratio of barium sulphite and plain water volume. 3. The lesions positioned in upper part within stomach exhibited their best discrimination performanance with depth in the low tube voltage, followed in order by the middle part and lower part. However, the discrimination performanance at the high tension radiography uniformly visualized over X-ray film without density in change.

Prospective study of lymph node imaging of twenty stomach cancer cases with dissected lymph nodes being injected into the submucosa layer of stomach under surgical field was done. Total dose of 5 mci in 5 cc of volume was injected along the multiple sites of the lesser and greater curvature of stomach and collected lymph nodes within 2 hour of surgical time were placed under gamma camera and lymph node imagings were obtained. Pathological invasion of tumor and correlation of cold defect or hot uptake was compared each other. Tumor invasion of nodes revealed cold defect area which was correlated well with the pathological specimen. Correlation rate was 84.6%. We are planning to extend these procedures and trying endoscopic injection of positive imgaing agents such as Ga-73-3 Ig 2 alpha in future.

Objective: The purpose of this study was to analyze the correlation between Stomach Qi Deficiency and gastric emptying as measured by abdominal ultrasonography in postprandial distress syndrome (PDS), a subgroup of functional dyspepsia (FD). Methods: Ten patients who met the Rome III diagnostic criteria for PDS and ten healthy controls participated in this study Gastric emptying shown as the half-life of gastric volume ($T_{1/2}$) was measured by abdominal ultrasonography. The degree of Stomach Qi Deficiency was assessed using the scale for Stomach Qi Deficiency pattern (SSQD). In addition, functional dyspepsia-related quality of life (FD-QoL), Nepean dyspepsia index-Korean version (NDI-K), and visual analogue scale (VAS) of distention and fullness were conducted on all subjects. Results: The scores of SSQD, FD-QoL, NDI-K, and VAS of distention and fullness in the patient group were significantly higher than those in the control group (p<0.05). $T_{1/2}$ was also higher in the patient group than in the control group. The SSQD score significantly correlated positively with $T_{1/2}$ in the patient group (r=0.640, p=0.046). However, there was no significant correlation between $T_{1/2}$ and other questionnaire scores in the patient group. Conclusions: Our results suggest that the gastric emptying measured by abdominal ultrasonography could be a quantitative indicator to diagnose Stomach Qi Deficiency in FD patients, especially the PDS subtype.

Purpose: The significance of hospital volume remains inconsistent and controversial. In particular, few studies have examined whether hospital volume is associated with the outcome of gastrectomy for gastric cancer in East Asia. This study examined the effect of hospital volume on the short-term surgical and long-term oncological outcomes of patients undergoing curative gastrectomy for gastric cancer. Materials and Methods: Between 2009 and 2011, 1,561 patients underwent curative gastrectomy for gastric cancer at Seoul St. Mary's Hospital (n=1,322) and Bucheon St. Mary's Hospital (n=239). We defined Seoul St. Mary's Hospital as a high-volume center and Bucheon St. Mary's Hospital as a low-volume center. Results: The extent of resection, rate of combined resection, tumor stage, operating time, and hospital stay did not differ significantly between the 2 hospitals. In addition, the hospital volume was not significantly associated with the 30-day morbidity and mortality. When the overall and disease-free survival rates of the patients were stratified according to stage, hospital volume was not significantly associated with prognosis at any stage. Conclusions: Hospital volume might not be a decisive factor with respect to the surgical and oncological outcomes of patients if well-trained surgeons perform gastrectomy for gastric cancer.

The aim of this study was to investigate the effects of Ulmi Pumilae cortex extracts on acute reflux esophagitis rats induced by pylorus and forestomach ligation operation. 40 rats were divided into five groups; Normal group, Sham group, Control group, T1 group and T2 group. 4 groups has a laparotomy after controled 2weeks and sham group, T1 group, T2 group has ligation in stomach. After laparotomy, all group`s body weight, gastric volume, gastric juice PH, SOD activities, catalase activities, lipid peroxidation, total glutathione, the effects on esophageal and stomach mucosa damage were checked. There was significant statistical differences between control group and Ulmi Pumilae cortex extracts adminitration groups(T1 and T2 group) in terms of gastric volume decreasing. Also, adminitration groups has significant effect than control group in decreasing mucosa damage. SOD(superoxide dismutase) and catalase activities has a significant statistical differences between control group and T2 group not in T1 group. These results suggest that the medication of Ulmi Pumilae cortex extracts is effective for the treatment of acute reflux esophagitis in terms of decerasing gastric volume and mucosa damage. Especially, the results were shown to be more positive in High-dose administration group (T2 group) than in Low-dose administration group (T1 group) in SOD and catalase activities.

Objectives : This paper seeks to contribute to restoring ancient literature related to Bianque through literature analysis of the fifth volume of "Maijing(脈經)". Methods : Literature referenced in the fifth volume of "Maijing(脈經)" which are "Huangdineijing(黃帝內經)", "Nanjing(難經)" among others were examined. Results & Conclusions : The fifth volume of "Maijing(脈經)" cites "Huangdineijing(黃帝內經)", "Nanjing(難經)", "Bixi Zhenfa(敝昔診法)", "Ni Shun Wu Se Mai Zang Yan Jing Shen(逆順五色脈藏驗精神)" etc. Based on the question and answer format of the text, it seems the fifth volume of "Maijing(脈經)" is a collective of three different lines of medical texts. It shows traces of Bianque's Zangfu theory where the Stomach is considered as one of the Five Zangs instead of the Spleen. It also contains the diagnostic method of symptom expression time based on distance between sites of pathological expression. Moreover, description of the number of pulses during one cycle of breathing (inhale/exhale) indicates that the early theories of the Bianque School has been preserved.
