        N/A Background: According to the rapid changes in social environment such as increasing alcohol consumption and the marked improvement in diagnostic technique, we expect that there have been major changes in various aspects of acute pancreatitis during the recent 12 years in Korea. Methods: The medical records of 317 patients with acute pancreatitis diagnosed from 1980 through 1992 were reviewed about clinical, laboratory and radiological findings in the three different time period. Results: 1) There has been an increasing incidence in male sex about three folds. 2) There has been an increasing trends in the duration of hospitalization. 3) A significant increase was observed in the proportion of patients with alcoholic pancreatitis in the three different time period; 26.9%, 45.7%, 50.7% respectively. 4) The complication rates have been slightly increased in the three different time period; 46.3%, 47.1%, 59.1% respectively. But, the type of complications has not been changed. 5) There is increasing severity in non-gallstone group, but no significant differences in gallstone group. There is a declining trends in the number of patients with muld severity index, but increasing trend in the number of patients with moderate severity index in non-gallstone group. 6) There was no significant differences in mortality rate. Conclusions: There has been major changes in the etiology ans severity of acute pancreatitis from 1980 through 1992. Especially, significant increase in the proportion of patients with alcoholic pancreatitis was observed in the three differnt time period. These results might be due to socioeconomic changes.

        A study was planned to see if the Panax Ginseng has any influence upon the general activity of rats. Seventeen male rats (mean body weight: 204 g) was divided into a ginseng group (N=9) and a saline group (N=8). Once a day for 5 days they received subscutaneously 0. 5m1/100g body weight of ginseng extract solution (4 mg of ginseng alcohol extract in 1 ml of saline), and same amount of saline, respectively. For 20 days beginning from the 1st day of medication on, each rat received activity measurement by means of beam interruption method. Following results were obtained : 1. Activities at night (6 p.m. to 6 a.m. next morning) and in 24hours on the 10 th, 12th, and 13 th day were significantly increased in the ginseng group compared with activities of the saline group. 2. Summed total night and 24-hour activities observed for 15 days after termination of medication were also significantly augmented in the ginseng group compaired with those of the saline group, although no remarkable difference existed between the 2 groups with regard to the summed total daytime activity. It is inferred that the ginseng augments general activity of rats especically at night.

        목적: PPAR gamma 배위자의 항암 효과는 다양한 암세포에서 보고되었으나 담관암에 대한 연구는 부족한 실정이다. 본 연구에서는 한국인 간내담관암에서 확립한 암세포주를 대상으로 내인성 PPAR gamma 배위자인 15-deoxy-PGJ2의 항암 효과와 그 기전에 관하여 알아보았다. 방법: Cho-CK, Choi-CK, JCK, SCK의 네 가지 간내담관암 세포주를 사용하였다. RT-PCR 방법으로 PPAR gamma, bcl-2, bax 각 유전자의 mRNA 발현을 측정하였다. 세포증식 분석은 MTT assay, 세포주기 분석은 flow cytometry, 세포자 멸사 분석은 cell death detection ELISAplus kit를 사용하였다. 또한 Caspase 활성도 측정을 위해 caspase colorimetric assay kit를 사용하였고, MTT assay를 통해서 caspase 억제제가 15-deoxy-PGJ2의 암세포증식 억제를 차단하는지 알아보았다. 결과: 모든 담관암세포주에서 PPAR gamma mRNA가 발현 되었다. 15-deoxy-PGJ2를 5, 10, 25, 50, 100 mM 농도로 투여하여 72시간 배양하였을 때 모든 세포주에서 용량 및 시간 의존적으로 세포증식이 억제되었다. 세포주기 분석 결과 25 mM 15-deoxy-PGJ2 투여 48시간 후 모든 세포주에서 세포자멸사 분획이 증가하였으며 세포자멸사 유도 효과는 용량 의존적이었다. 25 mM 15-deoxy-PGJ2를 투여한 후 48시간까지 caspase 활성도를 측정하였는데, caspase 3 활성도는 모든 세포주에서 caspase 9 활성도는 JCK를 제외한 나머지 세포주에서 유의하게 증가하였으며 caspase 8 활성도는 별 변화가 없었다. Pancaspase 억제제인 Z-VAD-FMK와 caspase-3 억제제인 Z-DEVD-FMK를 투여한 경우 15-deoxy-PGJ2의 암세포증식 억제 효과가 48시간 이후 농도 의존적으로 차단되었으며, 이러한 효과는 모든 세포주에서 나타났다. 각 세포주에 15-deoxy-PGJ2를 투여 한 후 48시간까지 bcl-2 및 bax gene의 발현 유무를 관찰하였는데, bcl-2 mRNA는 Cho-CK, Choi-CK, SCK 세포 주에서 유의하게 감소하였으나 bax의 경우 모든 세포주에서 유의한 변화를 보이지 않았다. 결론: 한국인 간내담관암세포주 모두에서 PPAR gamma mRNA가 발현됨을 알 수 있었고, 내인성 PPAR gamma 배위 자인 15-deoxy-PGJ2가 세포자멸사 유도를 통해 담관암세포 증식을 용량 및 시간 의존적으로 억제하였다. Background/Aims: Peroxisome proliferator-activated receptor (PPAR)-γ ligand is known to inhibit the growth of several kinds of cancer cells, yet its effect on cholangiocarcinoma is indecisive. We investigated the effect of an endogenous ligand of PPAR-γ, 15-deoxy-δ (12,14)-prostaglandin J2 (15-deoxy-PGJ2) on cholangiocarcinoma cells that were established from intrahepatic cholangiocarcinoma tissue of Korean patients. Methods: Four cholangiocarcinoma cell lines, Cho-CK, Choi-CK, JCK and SCK, were studied. The mRNA expression of PPAR-γ, bcl-2, and bax were examined by RT-PCR. Cell viability was determined by MTT assay. The cell cycle was analyzed by flow cytometry, and apoptosis by cell death detection ELISA kit. Caspase activity was measured by colorimetric assay. The effect of caspase inhibitors on 15-deoxy-PGJ2-induced apoptosis was determined by measuring cell viability using the MTT assay. Results: PPAR-γ mRNA was expressed in all cholangiocarcinoma cells. 15-deoxy-PGJ2 inhibited proliferation of all cells in a dose- and time-dependent manner. All cells treated with 15-deoxy-PGJ2 showed increased dose-dependent apoptosis. Caspase 3 was activated in all cells and caspase 9 was activated in all but JCK cells after 15-deoxy-PGJ2 treatment. Caspase 8 activity showed no significant change. The pan-caspase inhibitor, Z-VAD-FMK, and the caspase-3 inhibitor, Z-DEVD-FMK, blocked 15-deoxy-PGJ2-induced apoptosis in all cells dose-dependently. The expression of bcl-2 was decreased in Cho-CK, Choi-CK and SCK cells, and bax expression was not changed significantly after 15-deoxy-PGJ2 treatment. Conclusions: PPAR-γ mRNA was expressed in all Korean cholangiocarcinoma cells. Our data suggest that 15-deoxy-PGJ2 exerts an antineoplastic effect against cholangiocarcinoma cells by inducing apoptosis through caspase activation. (Korean J Med 78:75-86, 2010)

        N/A The possible roles of gastric acid secretion in the pathogenesis of stress ulcers induced by restraint with water-immersion for 7 hours in pylorus-ligated rats were investigated. Control rats with pylorus-ligation only did not show any gastric mucosa} lesion, and their mean gastric acid output was 449.2 ± 36.1 umol/rat. In contrast, the stressed rats, group II, showed multiple, punctate and hemorrhagic erosions in gastric mucosa, and mean gastric acid output was decreased to the level of 253.7 ± 27.3 umol/rat. Subcutaneous administration of histamine(40 mg/kg every 2.5 h for a total three times) to stressed rats augmented the lesion with severe multiple, linear and hemorrhagic erosions and mean acid output increased significantly (328.1 ± 31.5 umol/, p<0.005) compared with group II. Pretreatment with rantidine(20 mg/kg) or prostaglandin E2 (30 ug/kg) before exposure to stress reduced gastric lesion formation slightly with no significance. In ranitidine pretreated rats, mean gastric acid output was decreased significantly (120.1 ± 15.3 umol/rat, p<0.005) compared with group II. However, in prostaglandin pretreated rats, mean gastric acid output showed no significant changes. Therefore, it is suggested that increased gastric acid secretion seems to be an aggravating or a permissive factor rather than a major factor in the pathogenesis of stress-induced gastric mucosal lesions.

        N/A Human cells are almost never spontaneously immortalized in vitro. We tried to immortalize human fetal hepatocytes (h-FH) and evaluate the differentiational status and its change. Methods : Hepatocytes were isolated from a liver fragment of 20 week old fetus and infected with amphotropic recombinant retrovirus containing a temperature- sensitive mutant of SV40 large T antigen and neomycin phosphotransferase gene. G418 resistant colonies were cloned and expanded. The cells which were able to divide more than 30 times were used to analyze various functions. Results : The immortalization rate was 3.3 x 10-8 and two cell lines (C11, D21) were established. C11-60, C11-80, D21-30 and D21-60 (suffix number means the cell division counts) were evaluated. D21-30 was thougt to be imcompletely immortalized because a considerable portion of cells died during culture. The morphology was similar to that of epithelial cells except for D21-30 which looked like fibroblast. The cells grew rapidly at 33oC but stopped growing at 39oC. T antigen and p53 was expressed at 33oC but disappeared at 39oC, which suggest that T antigen binds to p53. Chromosomal changes were so marked that it was impossible to discriminate exact number. Albumin was secreted as about 1/10 as that of h-FH, but alpha-fetoprotein secretion stopped after immortalization. Telomerase was activated in both cell lines except for the incompletely immortalized cells D21-30. Telomere was elongated in competely immortalized cell lines, but it was rather shortened in D21-30 compared to that of h-FH. Macroscopic colonies did not develop in soft agar assay. Conclusions : We successfully immortalized human fetal hepatocytes. Although the cells are not likely to have oncogenicity, the functions are not so good, possibly due to marked chromosomal changes which are thought to occur before telomerase is activated during immortalization step.

        김병호(Byung Ho Kim),이정일(Joung Il Lee),장영운(Young Woon Chang),장린(Rin Chang),민영일(Young Il Min) 대한내과학회 1987 대한내과학회지 Vol.32 No.6

        N/A We performed clinical study about patients with chronic hepatic disease who had small hepatic nodule less than 3 cm in diameter in real time ultrasonography. 18 cases, that is 9 cases of liver cirrhosis, 5 cases of chronic hepatitis and 3 patients with had a history of type B viral hepatitis were included in this study. Sono-guided aspiration cytology and serum a-FP measurement in all subjects, celiac angiography in 6 cases and abdominal CT scan in 2 cases was performed. In 4 patients with compatible findings of HCC (hepatocellular carcinoma) in celiac angiography, 3 gave positive result in aspiration cytology but 1 gave negative result. In 2 patients with compatible findings of hemangioma in celiac angiography, all showed dysplastic hepatocytes in aspiration cytology and echogenic nodule in ultrasonography. In 3 patients with small HCC confirmed by surgery, abdominal CT scan couldn't discover the mass and in a patients with hemangioma confirmed by surgery, abdominal CT scan could discover the mass, but the nature of the mass couldn't be well defined. Among 4 cases of cytologically confirmed hepatoma, only 2 cases had significantly elevated α-FP level.

        Alendronate (Fosamax), an aminobisphosphonate and a selective inhibitor of osteoclast-mediated bone resorption, is used to treat postmenopausal osteoporosis and Paget's disease. In recent years, reports of severe esophageal injury in patients who took alendronate have evoked attention to the irritant effects of this drug on the mucosa of the upper gastrointestinal tract. We present a case of gastric ulcer caused by alendronate. The patient chiefly complainted of epigastric pain during 14 days. She had taken mefenamic acid for pain control for 3 years and she took once-weekly 70 mg of alendronate for 2 weeks for treatment of osteoporosis before the symptom started. Upper gastrointestinal endoscopy revealed two active gastric ulcers in the low body. The results of rapid urease test (CLO test) and modified Giemsa test for the detection of Helicobacter pylori infection were negative. After withdrawal of alendronate, the symptom resolved completely in one week. Six weeks later, follow-up endoscopy showed complete healing of the ulcer. (Korean J Gastroenterol 2001;38:284-287)

        Background/Aims: The aim of this study was to evaluate the change in circulating levels of adipokines, including leptin, adiponectin, resistin, and visfatin, after induction therapy of patients with active inflammatory bowel disease (IBD). Methods: We prospectively evaluated 20 patients with Crohn’s disease (CD) and 14 patients with ulcerative colitis (UC) who received induction therapy. The disease activity, body mass index (BMI), and C-reactive protein (CRP) and serum adipolines levels were checked before treatment and 10 weeks after treatment. Results: After induction therapy, significant reduction of disease activity was noted in patients with CD (CD activity index, 267.9±73.7 vs. 50.8±36.5, P<0.001) and patients with UC (Mayo score, 9.8±2.2 vs. 1.4±1.6, P<0.001). The mean serum leptin, adiponectin, resistin, and visfatin levels were 4.0±2.7 ng/mL and 4.4±2.3 ng/mL (P=0.323), 27.0±20.5 μg/mL and 33.8±26.5μg/mL (P=0.084), 9.0±4.0 ng/mL and 10.2±3.2 ng/mL (P=0.108), and 4.6±3.7 ng/mL and 2.5±4.1 ng/mL (P=0.046) before and after infliximab treatment, respectively. No significant correlation between the changes in BMI, CRP level, or the clinical indices of activity and alterations of the measured adipokines was demonstrated. Conclusions: The serum levels of leptin, adiponectin, and resistin showed no significant alterations, whereas the serum visfatin level decreased significantly after induction therapy, suggesting a possible pro-inflammatory property of visfatin and a role as a marker of successful therapy of IBD.
