        The purpose of this study was to evaluate the decreasing effects of Korean garlic against the accumulation of mercury levels in maternal and fetal organs in pregnant Fischer 344 rats, based on the theory and information that neutral amino acids have protective effects against mercury poisoning and garlic contains a large of neutral amino acids. The results obtained are as follows: 1. On the 20th day of gestation, the maternal body weight in 20 mg/wt$\cdot$kg methyl mercuric chloride groups was 76.1% of those in control group, but those recovered to be 81.2% and 93.6% by treating with garlic (0.5 g/wt$\cdot$kg and 1.0 g/wt$\cdot$kg). 2. The mercury levels in maternal organs were reduced 6.2% and 47.2% (p<0.05) in kidney, 8.2% and 42.1% (p<0.05) in spleen, 9.7% and 40.9% (p<0.05) in blood, 35.6% (p<0.05) and 67.2% (p<0.05) in liver, 38.0% (p<0.05) and 57.6% (p<0.05) in brain, by treating with garlic (0.5 g/wt$\cdot$kg and 1.0 g/wt$\cdot$kg). 3. The mercury levels were reduced 22.4% and 44.3% (p<0.05) in placenta, and 34.7% (p<0.05) and 54.9% (p<0.05) in fetal body, by treating with garlic (0.5 g/wt$\cdot$kg and 1.0 g/wt$\cdot$kg). 4. The mercury levels in fetal organs were reduced 17.5% and 46.7% (p<0.05) in kidney, 15.1% and 37.0% (p<0.05) in brain, 30.2% (p<0.05) and 46.7% (p<0.05) in liver, by treating with garlic (0.5 g/wt$\cdot$kg and 1.0 g/wt$\cdot$kg). 5. Mercury levels in maternal kidney were 6.73~7.71 times higher than those in fetal kidney, but those in fetal liver and brain were 1.67~2.25 times and 1.98~2.93 times higher than those in maternal liver and brain, respectively. In conclusion, Korean garlic decrease the accumulation of mercury levels in maternal and fetal organs in pregnant Fischer 344 rats as increasing the dose.

        이진헌 공주대학교 환경문제연구소 2017 환경연구 Vol.17 No.-

        Korean National Survey for Environmental Pollutants in Human Body (KorSEPs) was performed for preparing the Korea National Environmental Health Survey (KNEHS) as a pilot study. The German Environmental Survey (GerES), National Human Exposure Assessment Study (NHEXAS) and National Health Nutrition Examination Survey (NHANES) were referenced for making design and sampling strategies of KorSEPs. Sampling units and participants were 2,273 persons within 80 units at KorSEP Ⅱ, and 5,129 persons within 200 units in KorSEP Ⅲ. Analytes were increased to 13 items such as Pb, Hg, Mn, Cd, As, 2-naphthol, 1-OHP, cotinine, metabolites of phthalates, bisphenol A, 3-PBS, metabolites of benzene and toluene. Two kinds of questionnaires were developed; one for families and another for individuals. In Korean adults, the geometric means of the blood lead, mercury, cadmium and manganese levels were 19.1, 3.23, 0.65 and 10.8 ㎍/L, respectively. The geometric concentrations of the urinary 2-naphthol (2-NP) and 1-hyroxypyrene (1-OHP) were 3.84 ㎍/L (95% CI: 3.57-4.11) and 0.15 ㎍/L (95% CI: 0.15-0.17), those of urinary cotinine concentrations were 769.9 ㎍/L (95% CI: 611-929) among smokers and 21.5 ㎍/L (95% CI: 19.1-23.9) among non-smokers in KorSEP Ⅲ. Of metabolites of phthalates, the concentrations of Mono-(2-ethyl-5-bydroxyhexyl)-phthalate (5-OH), Mono-(2-ethyl-5-oxohezyl)-phthalate (5-OXO), and Mono-N-butyl phthalate (Mn-BP), were 13.3 ㎍/L (95% CI: 12.6-14.1), 11.1 ㎍/L (95% CI: 10.4-11.8), 44.9 ㎍/L (95% CI: 42.2-47.8), respectively. Also, the concentrations of bisphenol A (BP-A) and 3-phenooxybenzoic acid (3-PBA) were 0.71 ㎍/L (95% CI: 0.64-0.79) and 1.82 ㎍/L (95% CI: 1.69-1.95), prespectively.

        담췌관 합류부위의 형태와 담췌관 질환

        이진헌,강진경,박인서,문영명,정재복,송시영,박형우 대한소화기내시경학회 1998 Clinical Endoscopy Vol.18 No.5

        Background/Aims: The anatomy of the distal ends of the common bile duct and the main pancreatic duct has received attention becauwe of its importance in pancreaticobiliary disense. The two ducts open into the duodenum either separately or via a common channel. But basie data about the pancreaticabiliary ductal union system has not existed in Korea until now. Methods: In this study all cases performed with an ERCP were reviewed over the past 5 years (1992.1.1 1996.12.31). Among 3,234 cases, 307 were selected and analyzed because of their clear identification by the pancreaticobiliary ductal union system. Results: 1. The mean age of the subjects was 54.3 years with 156 male and 151 female cases (M : F=1.03 : 1). 2. The underlying diseased in these cases were gallbladder stones 25.7 %, bile duct stones-22.8 %, cholangitis-20.5 %, bile duct cancer-9.1 %, choiecystitis8.8%, chronic pancreatitis-7.5%, and others-30.1%, respectively. 3. The common channel was found in 73.9% of the cases, with 26.1% having separate openings for the two ducts. 4. The length of the common channel was on the average 4.2±3.8 mm, and 11 % of the cases exceeded 8 mm. The anomalous pancreaticabiliary dutal union (APBDU) was found in 2.2%. 5. The incidence of congenital choledoiwhal cyst was increased with the longer common channel length (≥8 mm). The gallbladder cancer and gallstone induced pancreatitis show increased frequency with a longer common channel, but no significant statistical results were found. 6. In the separate opening type, the incidence of alcohol induced chronic pancreatitis was higher. Conclusion: The common chatmel was noted in 73.9% and 26.1% with a separate opening type. The length of the common channel was on the average 4.2±3.8 mm. There was a higher incidence of congenital choledochal cysts with a long comtnan channel (≥ 8 mm). The length of the common channel was longer in cases with congenital choled~ochal cysts or gallbladder cancer than that of the other cases. The separate opening type was associated with a higher incidence of alcohol induced chronic pancreaiitis than of the common channel type.

        내시경적 역행성 담췌관 조영술상 췌관의 형태와 질환과의 관계

        이진헌,박승우,이준규,강진경,정재복,송시영,서정훈 대한소화기내시경학회 2000 Clinical Endoscopy Vol.20 No.1

        Background/Aims: The advent of endoscopic retrograde cholangiopancreaticography (ERCP) has made it possible to identify the pancreatic ductal (PD) system. There is no established relationship between the PD system and various pancreaticobiliary diseases. The purpose of this study was to identify the morphological diversities and anatomical variations of PD and to define the relationship between PD types and pancreaticobiliary diseases. Methods: Five hundred and eighty-two consecutive patients, in whom both PD and common bile duct (CBD) were clearly visualized by ERCP, were included. PD types were categorized according to the relationship between CBD and PD. The anatomical variations were classified into migration, fusion, and duplication anomalies. Results: The PD types were classified into type A 84.4%, type B 9.6%, type C 3.4%, and type D 2.6%. The PD anomalies were noted in 51 patients, which were comprised of 19 (3.3%) fusion anomalies (12 complete pancreas divisum, 7 incomplete pancreas divisum) and 32 (5.5%) duplication anomalies (5 number variations, 27 form variations). No significant relationships between various PD morphologies and pancreaticobiliary diseases were found. Hyperamylasemia was more frequently complicated in type C (41.7%) and D (50%) than in type A and B after ERCP. Conclusions: Though a close relationship was not found between various PD types and pancreaticobiliary diseases, being familiar with the morphology and anatomical variation is worth it, for more accurate interpretation and for prediction of a complication such as pancreatitis.

        Helicobacter pylori 감염은 상부위장관 및 대장 병변을 동시에 일으킬 수 있는가?

        이진헌,이기성,이자영,김학양,유재영,박충기,김종혁,김용범,장웅기,김성균,김억,서중산 대한소화기내시경학회 2001 Clinical Endoscopy Vol.22 No.1

        Background/Aims: Some studies showed the higher prevalence of K. pylori infection in the patients with colon adenoma and carcinoma than control subjects. The association between H. pylori infection and colonic diseases is controversial. We evaluated K. pylori infection rate and the related upper gastrointestinal lesions in the patients with colon polyp and cancer. Methods: Ninety-four subjects, 67 with colonic lesions and 27 without colonic lesions were enrolled. Colon polyp and cancer were confirmed by colonoscopic biopsy or polypectomy. The enrolled subjects were received gastroduodenoscopic examination. K. pylori infection was evaluated serologically and/or with rapid urease test. The fasting serum gastrin level was measured. Results: H. pylori infection rates in the patients with and without colonic lesions were 67.2% and 44.4%, respectively (p$lt;0.05). Upper gastrointestinal lesions were observed in 27 of 67 patients (40.3%) with colonic lesions and in 11 of 27 patients (40.7%) without colonic lesions (p=l.0). Mean levels of serum gastrin with and without colonic lesions were 91.7±31.1 pg/mL and 88.1±37.7 pg/mL, respectively (p=0.15). Conclusions: Our study supports the relationship between H. pylori infection, colorectal neoplasia. Although there was no significant difference, the possibility of the simultaneous presence of upper gastrointestinal lesions in the patients with colorectal polyp and cancer was suggested. But the relationship between serum gastrin and the development of colorectal polyp and cancer was not documented.

        To identify and evaluate the benzidine-DNA adducts in liver and bladder, we exposed the 80 ppm benzidine to 40 sprague-dawley rats by drinking water for 4 weeks(6.2 mg/kg body wt./day). Only one benzidine-DNA adduct was found at the same site of thin layer chromatogram of $^{32}$ P-postlabeling method in the liver and bladder of exposed rats. So we know the DNA adduct formed at liver and bladder were similar to each other, which was N-(deoxyguanosin-8-yl)-N'-acetylbenzidine. Relative adduct labeling(RAL) of DNA adduct was similar to each other for 1 and 2 weeks, but that in liver was significantly higher than in bladder for 3 and 4 weeks. RAL$\times$10$^{9}$ of DNA adduct were 84.45$\pm$11.31 and 152.8$\pm$5.53 in liver, and were 24.76$\pm$7.06 and 38.00$\pm$10.57 in bladder for 3 and 4 weeks, respectively. Regression equation between liver and bladder was Y=-3.801+2.507 X(r=0.6036, p<0.01). In conclusion, benzidine-DNA adduct formed in liver was significantly higher than that in bladder, with the similar compound structure in sparague-dewley rates treated benzidine in drinking water.
