Purpose: The aim of this study was to establish an anthropometric reference of the stomach for gastric cancer surgery and a modeling formula to predict stomach length. Materials and Methods: Data were retrieved for 851 patients who underwent total gastrectomy at the Seoul National University Hospital between 2008 and 2013. Clinicopathological data and measurements from a formalin-fixed specimen were reviewed. The lengths (cm) of the greater curvature (GC) and lesser curvature (LC) were measured. Anthropometric data of the stomach were compared according to age, body weight, height (cm), and body mass index. To predict stomach length, two multiple regression analyses were performed. Results: The mean lengths of the GC and LC were $22.2{\pm}3.1cm$ and $16.3{\pm}2.6cm$, respectively. The men's GC length was significantly greater than the women's ($22.4{\pm}3.1cm$ vs. $21.2{\pm}2.9cm$, P=0.003). Patients aged >70 years showed significantly longer LC than those aged <50 years ($16.9{\pm}2.9cm$ vs. $15.9{\pm}2.4cm$, P=0.002). Patients with body weights >70 kg showed significantly longer GC than those with body weights <55 kg ($23.0{\pm}2.9cm$ vs. $21.4{\pm}3.2cm$, P<0.001). In the predicted models, 4.11% of the GC was accounted for by age and weight; and 4.94% of the LC, by age, sex, height, and weight. Conclusions: Sex, age, height, and body weight were associated with the length of the LC, while sex and body weight were the only factors that were associated with the length of the GC. However, the prediction model was not sufficiently strong.

Objective: Excision repair cross-complementing group 6 (ERCC6) is a major component of the nucleotide excision repair pathway that plays an important role in maintaining genomic stability and integrity. Several recent studies suggested a link of ERCC6 polymorphisms with susceptibility to various cancers. However, the relation of ERCC6 polymorphism with gastric cancer (GC) risk remains elusive. In this sex- and age-matched case-control study including 402 GC cases and 804 cancer-free controls, we aimed to investigate the association between a potentially functional polymorphism (rs1917799 T>G) in the ERCC6 regulatory region and GC risk. Methods: The genotypes of rs1917799 were determined by Sequenom MassARRAY platform and the status of Helicobacter pylori infection was detected by enzyme-linked immunosorbent assay. Odd ratios (ORs) and 95% confidential interval (CI) were calculated by logistic regression analysis. Results: Compared with the common TT genotype, the ERCC6 rs1917799 GG genotype was associated with increased GC risk (adjusted OR=1.46, 95%CI: 1.03-2.08, P=0.035). When compared with (GT+TT) genotypes, the GG genotype also demonstrated a statistical association with increased GC risk (adjusted OR=1.38, 95%CI: 1.01-1.89, P=0.044). This was also observed for the male subpopulation (GG vs. TT: adjusted OR=1.71, 95%CI: 1.12-2.62, P=0.013; G allele vs. T allele: adjusted OR=1.32, 95%CI: 1.07-1.62, P=0.009). Genetic effects on increased GC risk tended to be enhanced by H. pylori infection, smoking and drinking, but their interaction effects on GC risk did not reach statistical significance. Conclusions: ERCC6 rs1917799 GG genotype might be associated with increased GC risk in Chinese, especially in males.

An analytical methodology based on solid-space extraction (SPE) with with Bond Elut Certify cartridge (Varian, 130 mg) has been developed for the qualification and quantitation of strychnine in blood. After the elution layer was evaporated, the residue was reconstituted with methanol for GC/MS. Internal standard was used 10 mg/l dextromethorphan. Strychnine is a potent central nervous stimulant and convulsant, and an alkaloid found in seeds of Strychnos nux-vomica. It was used therapeutically to improve circulation and muscle tone in oral or intramuscular doses of 0.05~8 mg. The fatal dose of strychnine for humans is 50~100 mg. A man was found dead lying curled up the corner of the large room in a roof house after the fire fighter opened a locked door inside to put out the fire. The postmortem blood and gastric contents were analyzed for toxicological testing. Strychnine and brucine were detected using GC/MS first in gastric contents extracts. The contents of strychnine was 0.083 mg/l in heart blood, 0.088 mg/l in peripheral blood and 4.0 mg/kg in gastric contents, respectively. Method validation was carried out in terms of linearity, accuracy, precision (intraday, interday) in blood. The assay is linear over 0.05~10 mg/l ($r^2$=0.999). Limit of detection (LOD) and limit of quantitation (LOQ) in blood were determined 0.02 mg/l (S/N=3) and 0.07 mg/l (S/N=10), respectively. Accuracy (bias%) of strychnine with 0.1, 1 and 10 mg/l was 12.0% (n=6), 9.3% (n=6) and 6.9% (n=6), respectively. Intraday precision (CV%) of strychnine with, 0.1, 1 and 10 mg/l were 6.4%, 10.4%, 1.2% (n=6), respectively. Interday precision (CV%) of strychnine with 0.1, 1 and 10 mg/l over three days were 24.0%, 18.5%, 13.8% (n=18), respectively. Relative recovery with 0.1, 1 and 10 mg/l (in blood) were 114.9%, 99.3% and 87.4% (n=6), respectively. The described method can be applied in forensic toxicology to determine strychnine in blood samples.

Background/Aims: Dong-Moo Lee Jae-Ma(1837-1900) confirmed the sasangchaejil theory based on the sasang-medicine. This theory has been the main-stem of oriental medicine during 100 years in Korea. But rarely anyone has tried to prove this theory systemicaly. So we have a trial to clarify any relationship between the sasangchaejil and the laboratory and clinical results of mass screening tests. Methods: We evaluated the laboratory values of 280 people who had taken many clinical and laboratory tests. The laboratory examinations were complete blood count, liver and kidney function test, ultrasonogram of the abdomen and breasts, gastrofiberscope, many tumor markers body mass index, blood pressure, glucose, and electrocardiogram, etc. Results: 1) Among the 280 subjects, 187/66.8% were sowumin, 58/20.7% were taewumin and 35/12.5% were soyangin. 2) Those who reacted positive to HBsAb were 22 subjects(62.8%) in soyangin, 57.2% in sowumin and 55.1% in raewumin. But there were no significant correlations. 3) 45 subjects(72.4%) in taewumin had obesity, fatty liver and hyperlipidemia.(P<0.05) 4) 20.6% in taewumin had abnormal LFT suggesting hepatic disease. It was statistically sigificant.(P<0.05) 5) An anemic state was present in women of soyangin and sowumin mostly. Since an iron deficiency anemia is common in women, there were no significant corelations among sasangchaejil. Also urinary tract infectons were common in women. 6) 6 subjects in taewumin(10.3%) had cardiac problems, while only one case(2.8%) occured in soyangin and 7 cases(3.7%) in sowumin. Taewumin was significantly high.(P<0.05) 7) In the case of gastric disease, there was no distinguishable difference among sasangchaejil.(taewumin 37.9%, soyangin 31.4% and sowumin 35.2% rrespectively) 8) There was no significant difference beteen subjects with different blood types using sasangchaejil. Conclusions: There were some significant relationship between sasangchaejil and diseases prevalent to them by the theory of sasang-medicine. But Lee didn't considered the differences of gender, the change of body status according to the development of culture, and circumstances of their lives. Also he didn't consider the existence of infectious agents. Now more systemic study with larger populations are requied.

Acinar cell carcinoma is a rare tumor that represents 1~2% of all pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease. Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-old man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased $^{18}F$-fluorodeoxyglucose (FDG) uptake. Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the pancreas. The patient underwent a total gastrectomy three months later because of gastric recurrence. Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy. During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabine.

Background/Aims: Intragastric balloon (IGB) is the only available endoscopic bariatric and metabolic therapy in Korea. End-ball (Endalis) has the longest history of clinical use among the IGBs available in Korea. However, little clinical data on this system have been reported. In this study, we aimed to evaluate the efficacy and safety of End-ball in Korea. Methods: We performed a retrospective cohort study of patients who underwent IGB insertion (End-ball) from 2013 to 2019. Demographic and anthropometric data were collected. The efficacy and safety of IGB treatment were analyzed. Results: In total, 80 patients were included. Mean age was 33.7 years and 83.8% were female. Initial body mass index was 34.48±4.69 kg/m². Body mass index reduction was 3.72±2.63 kg/m² at the time of IGB removal. Percent of total body weight loss (%TBWL) was 10.76%±6.76%. Percentage excess body weight loss was 43.67%±27.59%. Most adverse events were minor, and 71.4% of participants showed nausea, vomiting, or abdominal pain. Conclusions: IGB treatment showed good efficacy and safety profile in Korean patients with obesity. In terms of %TBWL and percentage excess body weight loss, the efficacy was similar to that in the Western population.
