Abnormal gastric emptying time of dog by alien substance, neoplasm, pyloric antrum hyperplasia, stomach surgery, electrolyte imbalance, stomach-dilated torsion is clinically important as a digestive disease. Therefore study aims to provide basic data on the clinical usefulness of gastric emptying time test which uses radiopaque Kolomark developed in Korea rather than using the existing BIPS for the dog. 9 beagles were used for this experiment and their average weight was about 10.3kg with 2.5 year-old average age. For the test, fast for 12 hours was made without chemical sedation, and just before the test, 1 capsule of Kolomark was fed with 25% of daily feed amount, and we took photographs at ventrodorsal and right lateral position after 2, 4, 8 and 12 hours. As for interested reading area, we observed entire stomach from cardia to stomach pyloric part, and as for analysis method, we counted Kolomarks remained in the stomach per time and judged only P value below 0.05 to be meaningful by using Friedman Test. After feeding Kolomark through oral cavity, it took average 7.55 hours for the Kolomark to have escaped from the stomach to small intestine. In this study of gastrointestinal tract passing time after feeding matured dog, we used Kolomark and expect that it could be a basic data for normal gastrokinetic time.

Lactic acid bacteria are widely known to prevent and treat intestinal health conditions, heart disease, depression, and obesity. In Korea, such bacteria are commonly consumed through various fermented foods, although most are isolated from kimchi, and research on the lactic acid bacteria in fermented seafood is insufficient. This study was therefore conducted to observe changes in bacterial flora according to the culture date of lactic acid bacteria in the fermentation of traditional Korean Gajami Sikhae produced in Pohang and to isolate the bacteria of probiotic value. The bacteria were periodically isolated and identified from date of preparation to 50 days after preparation to investigate which Lactobacillus are involved in Gajami Sikhae. As fermentation progressed, it was confirmed that Pediococcus sp. and Lactobacillus sp. participate predominantly in the early and later periods of fermentation, respectively. During the entire fermentation period, 170 isolates were screened, and the following five species were found to be involved: Pediococcus pentosaceus, Pediococcus inopinatus, Leuconostoc mesenteroides, Lactobacillus brevis, and Lactobacillus plantarum. Five strains of these species were selected through acid and bile tolerance tests, and their coaggregation, autoaggregation, hydrophobicity, antibacterial, and antioxidant activities were then evaluated. As a result, it is thought that L. brevis GS1022, which has excellent digestive fluid resistance, and P. inopinatus GS316, which has excellent cohesiveness, may be useful as probiotic strains.

Objectives: The aim of this study was to determine the factors associated with the spatial distribution of the incidence of colorectal cancer (CRC) in the neighborhoods of Tehran, Iran using Bayesian spatial models. Methods: This ecological study was implemented in Tehran on the neighborhood level. Socioeconomic variables, risk factors, and health costs were extracted from the Equity Assessment Study conducted in Tehran. The data on CRC incidence were extracted from the Iranian population-based cancer registry. The $Besag-York-Molli{\acute{e}}$ (BYM) model was used to identify factors associated with the spatial distribution of CRC incidence. The software programs OpenBUGS version 3.2.3, ArcGIS 10.3, and GeoDa were used for the analysis. Results: The Moran index was statistically significant for all the variables studied (p<0.05). The BYM model showed that having a women head of household (median standardized incidence ratio [SIR], 1.63; 95% confidence interval [CI], 1.06 to 2.53), living in a rental house (median SIR, 0.82; 95% CI, 0.71 to 0.96), not consuming milk daily (median SIR, 0.71; 95% CI, 0.55 to 0.94) and having greater household health expenditures (median SIR, 1.34; 95% CI, 1.06 to 1.68) were associated with a statistically significant elevation in the SIR of CRC. The median (interquartile range) and mean (standard deviation) values of the SIR of CRC, with the inclusion of all the variables studied in the model, were 0.57 (1.01) and 1.05 (1.31), respectively. Conclusions: Inequality was found in the spatial distribution of CRC incidence in Tehran on the neighborhood level. Paying attention to this inequality and the factors associated with it may be useful for resource allocation and developing preventive strategies in at-risk areas.

Hwangheuk-san (HHS) is a Korean multi-herb formula comprising four medicinal herbs. HHS, which was recorded in “Dongeuibogam,” has been used to treat patients with inflammation syndromes and digestive tract cancer for hundreds of years. However, little is known about its anti-tumor efficacy. The present study investigated the pro-apoptotic effect and mode of action of HHS against AGS human gastric carcinoma cells. HHS inhibited the cell growth of AGS cells in a dose-dependent manner, which was associated with the induction of apoptotic cell death, as evidenced by the formation of apoptotic bodies, chromatin condensation, and an accumulation of cells in the sub-G1 phase. HHS-induced apoptotic cell death was associated with the up-regulation of pro-apoptotic Bax protein expression, down-regulation of antiapoptotic Bcl-2 protein, and the release of cytochrome c from mitochondria to the cytosol. The treatment of AGS cells with HHS significantly elevated the generation of reactive oxygen species (ROS). Additionally, apoptosis-inducing concentrations of HHS induced the activation of both caspase-9 and -8, initiator caspases of the mitochondrial-mediated intrinsic and death receptor-mediated extrinsic pathways, respectively, and caspase-3, accompanied by proteolytic degradation of poly (ADP-ribose)-polymerase. However, ROS scavenger and pan-caspases inhibitor significantly blocked HHS-induced growth inhibition and apoptosis. Taken together, these findings suggest that HHS induces apoptosis through ROS- and caspase-dependent mechanisms and that HHS may be a potential chemotherapeutic agent for the control of human gastric cancer.

The electron donating ability and nitrite scavenging activity were measured in ethanol extracts from the raw, simple cooked and seasoned materials of Bibimbab (mixed rice), a Korean traditional one-dish meal. The ethanol extracts of raw fragrant edible wild aster exhibited the highest electron donating ability $(80.28\%)$, as measured by the DPPH method. When Bibimbab was compared with Kimbab and hamburgers, which are popular food, it showed the highest antioxidative activity by the DPPH method. The nitrite scavenging ability was measured in an environment similar to in human digestive organs, i.e. pH $1.2\~6.0$. Generally, the antioxidative activity decreased in the sequence pH 1.2, 3.0 and then 6.0. The simple cooked materials, with the exception of fragrant edible wild aster, increased the antioxidative potential. The seasoned materials also had a tendency to increase the antioxidative potential. In conclusion, the ethanol extract of Bibimbab showed the highest nitrite scavenging activity. Therefore, the nutritional superiority of Bibimbab was confirmed through its electron donating ability, as measured by the DPPH method, and nitrite scavenging effect.

A case of foregut cyst communicated with esophagus and lined by bronchial mucosa is reviewed and its embryologic base of maldevelopment is discussed. It is not always easy to distinguish between digestive and respiratory cyst in mediastinum. There is whole range of intermediate between a cyst with ciliated and one with squamous or columnar mucosa. Origin of this dysembryoplasia is difficult to determine when one consider that the esophagus is covered with ciliated epithelium until the eleventh week of fetal life and that ciliated growth are found on its wall until the sixth month of the fetal life. And we concluded, general agreement is that cysts which have gastric epithelium in whole or in part, represent a distinct type and should be classified as (gastro) enteric cyst, mediastinal cyst containing cartilage were considered definitely as respiratory(bronchial or bronchogenic) cyst.

Thirty piglets weaned at 24.5 d of age ($6.9{\pm}0.5kg$) randomly alloted to 3 treatments were used to investigate the effect of dietary tallow on average performance, digestibility of nutrients, metabolic utilization of energy and body composition at 25 kg. Weaned piglets respond to increasing levels of dietary tallow from 0 to 4% and 8% by digestive and metabolic adaptation. Apparent fecal digestibility of fat (AFDf) was highly correlated with the level of dietary tallow (X as % of fat extracted after HCl hydrolysis) by the following curvilinear equation of regression: $AFDf=33.8+6.9X-0.3X^2$. Feed intake expressed as DE was only significantly increased at the higher inclusion level of tallow. But neither average daily gain, nor feed conversion was affected by the addition of fat. On the other hand, body composition at 25 kg was equally affected, by both levels of supplementary fat; dry matter and energy content in the body were significantly higher (p<0.01) in piglets receiving tallow. As a consequence, the energy cost of the live weight gain was also increased from 23 to 24.7 MJ DE/kg (p<0.02) and the efficiency of energy deposition was decreased from 3.2 to 2.8 MJ DE/MJ deposited energy (p<0.01) in the presence of dietary tallow. An increase in the level of fat stimulated the activity of pancreatic lipase up to a constant value of $22{\pm}1.4IU/mg$ protein but conversely depressed the activity of amylase from 300 to 100 IU/mg of protein. The activity of liver acetyl CoA carboxylase and malic enzyme in the perirenal fat were low lind not affected by dietary fat; the activity of glucose-6-phosphate dehydrogenase was high. Opposite to that, the activity of acetyl CoA carboxylase and malic enzyme in the perirenal and backfat were higher than in the liver and both were significantly reduced by the inclusion of fat in the diet. A direct deposition of dietary fat has been demonstrated by increasing the energy and lipid content of the empty body weight gain between 7 and 25 kg of live weight, and decreasing the efficiency of digestible energy utilization.

Objective Many literature-based researches and clinical studies have been thus far reported of wha-byuong in Oriental medicine but acupunctural approaches to it have been little executed, which motivated this study to be conducted through acupunctural treatment. For that purpose, this study carried out incessant treatment on wha-byuong-having outpatients of this hospital who were suffering from gunhwa of wha in the saam acupuncture in order to inquire into the features of wha-byuong represented recently, and thereupon this got some intellect and knowledge out of clinical cases, which led this study to report them. Methodology Two wha-byuong outpatients were taken as subjects for this study who visited this hospital from January 10, 2002 through May 20, 2002. As for the contents of treatment and the administration of medicine, acupuncture utilized size $30{\times}50mm$ needles and the performance of treatment depended upon yuchim for 20 to 40 minutes at one time by means of simseunggyok (eumgok, sohae bo, taebaek, sinmun sa) on both right and left sides of the outpatients. As the case may be, sobu, baekhoi, and pungji were used at the same time. Bosa of simseunegyok took youngsu bosa. In order to evaluate treatment, symptoms were classified with diagrams into physical symptoms, dorgan symptoms, urinogenital organs symptoms, dermatological symptoms, cardiopulmonary symptoms, musculoskeletal symptoms, somnipathy symptoms, caput and sensual organ symptoms, psychomotor activity symptoms, and other symptoms, and then signs and marks were given to indicate the most objective values according to symptoms of the patients perceived in different sessions both prior and posterior to treatment. Conclusion As a result of having conducted treatment on two outpatients who visited this hospital for their wha-byuong from January 10, 2002 through May 20, 2002, conclusions were obtained, as follows: 1. Treatment depended very largely upon simseunggyok of the saam acupuncture, and as the case may be, baekhoi, pungji and sobu were utilized at the same time. 2. Much more effects were produced only when the patients had got rid of the causes of wha-byuong they had. Furthermore, the perceived seriousness of the symptoms presented had not been improved, regardless of their wha-byuong, 3. The main symptoms complained by the patients such as sangyeolgam, anxieties, impatience, hungmin, difficulty in breathing, cardiopalmus, insomnia, digestive troubles, etc. showed for the most part conspicuous therapeutical effects upon the symptoms of wha-byuong. In particular, a high degree of improvement was represented from melancholia and pyrexia.

Even though the number of Korean Americans has dramatically increased over the last 20 years, there have been very few studies that have examined the health of this population. This paper investigates the contemporary health status of Korean Americans in comparison to Koreans, employing mortality related health measures: life expectance, age-specific death rates, and leading cause of death. Overall, we find that Korean American adults enjoy longer life expectancy and lower age-specific death rates than do their Korean counterparts, suggesting superior health status of the former as compared to the latter. Comparison of leading causes of death indicates that Korean American adults (age of 25-64) are more likely to die from neoplasms than are their Korean counterparts, while Koreans show a dramatically higher probability of death from liver-related diseases than Korean Americans. When these two cause of death are regressed on various demographic and socioeconomic factors, the difference in prevalence of neoplasms between the two populations disappeared, while that of liver-related diseases remains unaffected. Based on the outcomes from this research, we suggest that Korean Americans are a self-selected group in terms of health and socioeconomic status, and they adopt healthy behaviors after immigration. This has resulted in the relatively superior health of Korean Americans as compared to Koreans.
