These experiments were performed in order to study histologically and histochemically on the epithelial cells of gall bladder in Carassius carassius, Bufo bufo gargarizans, Natrix tigrina lateralis, Urloncha striata var. domesticus and Bos taurus var. domesticus. The results of the observation were as follows: 1. There were different cell types in the epithelium of gall bladder in each animal and it could not be supported histochemically that the epithelia cells of gall bladder were divided into two cell types of the rod-shaped and barrel-shaped ones. 2. The epithelium of gall bladder in Carassius carassius, Bufo bufo gargarizans, Natrix tigrina lateralis, Urloncha striata var. domesticus and Bos taurus var. domesticus was simple columnar epithelium. 3. The eosinophilities of cytoplasm in the epithelial cells of gall bladder were in uniform stronger in the upper portion of nucleus in Carassius carassius, Bufo bufo gargarizans and Natrix tigrina lateralis than its other portions, and in Urloncha striata var. domesticus and Lepus cuniculus var. domesticus existed uniformly in all portions, but there were many non-eosinophilic cells in Bufo bufo gargarizans and many cells that weakly eosinophilic around nucleus in Bos taurus var. domesticus. 4. The periodic acid Schiff's reactivities in the epithelial cells of gall bladder were different in each other and the epithelial cells in PAS reaction were divided into two cell types of the dark and light ones. There presented the light cells of 6.4%, 4.3% and 3.7% of epithelial cell of gall bladder in Carassius carassius, Bufo bufo gargarizans and Urloncha striata var. domesticus for each other, but were not presented in Natrix tigrina lateralis and Bos taurus var. domesticus. 5. The ninhydrin-Schiff-active proteins were much in the epithelial cells of gall bladder in Bos taurus var. domesticus, Carassius carassius, Urloncha striata var. domesticus and Natrix tigrina lateralis in order and were much in epithelial cells in the upper portion of mucosal folds in Carassius carassius, Urloncha striata var. domesticus and Natrix tigrina lateralis, and the ninhydrin-Schiff-active protein of the epithelium of gall bladder in Bufo bufo gargarizans was uniformly distributed. 6. The epithelial cells of gall bladder in Carassius carassius, Natrix tigrina lateralis, Urloncha striata var. domesticus and Bos taurus var. domesticus had no stain reactivity or weak stain reactivity to neutral fat and all epithelial cells in Bufo bufo gargarizans had strong stain reactivity, though they were different in quantity of epithelial cell portion. 7. The stain reactivities to RNA and DNA were stronger in the epithelial cells of the upper portion of mucosal fold than in those of other portions.

Purpose: Gall bladder (GB) stones in children are rarely observed, and so reports of them have been quite limited in Korea. Therefore, we tried to assess the epidemiology and clinical features of children with GB stone diagnosed at Severance Hospital. Methods: A clinical study was performed on 18 patients below 15 years of age diagnosed with GB stone by abdominal ultrasonography or CT scan at Severance hospital from January 1999 to May 2005. Results: Concerning patients' profile, their sex ratio of male to female in total 18 cases was 2 : 1 with the mean age of $6{\pm}4.3years$. 15 patients (83.3%) were asymptomatic. Inducing factors were found in 14 children (77.8%) including ceftriaxone therapy in 6 cases (33.3%), infection in 4 cases (22.2%), spherocytosis in 3 cases (16.7%), Down syndrome and abdominal operation in 1 case (5.6%) respectively. Single stone was found in 13 cases (76.5%) and multiple in 4 cases (23.5%). 15 cases (88.2%) had the stones less than 5 mm in size, and 2 cases (11.8%) between 5 and 10 mm. 17 patients received conservative treatment, and one patient had cholecystectomy due to Meckel diverticulum. Conclusion: In this report, Pediatric GB stones are predominant in male children, without typical symptoms, having inducing factors, single and small. Recently the diagnosis of them has been increased because of the development of imaging study. But the reports for them were still rare in Korea. Therefore the study for them is more necessary to find it's clinical characteristics.

Among the erythrocyte membrane defects, hereditary spherocytosis is the most common. The erythrocyte membrane defect results from a deficiency of spectrin, the most important structural protein in red cell. Hereditary spherocytosis often presents with hemolytic anemia, jaundice, moderate splenomegaly. Diagnosis is established by the presence of spherocytes in the peripheral blood, reticulocytosis, an increased osmotic fragility, and a negative Coombs test. In children, splenectomy is usually performed after age 6 years but can be done at a younger age if warranted by the severity of the anemia and the need for frequent transfusions. In the period December 1987 to Agust 1993, 9 patients with hereditary spherocytosis underwent splenectomy and the following results were obtained. 1. Nine patients were comprised of five males and four females. 2. Five patients(55.6%) had been admitted to our hospital during age 6-10 years. 3. Four of the nine patients had autosomal dominant inheritance with variable expression. The other five patients had no known inheritance. 4. The diagnosis of the spherocytosis was based on the increased osmotic fragility and increased autohemolysis of the erythrocytes, as well as on the appearance of spherocytes in the peripheral blood smear. 5. In all cases splenectomy was performed. Two patients had concomitant gall stones and choledocholithiasis, respectively. One patient with concomitant gall stones underwent simultaneous cholecystectomy and splenectomy. The other patient associated with choledocholithiasis underwent splenectomy, cholecystectomy, choledocholithotomy, and T-tube drainage. 6. Complete hematologic recovery was obtained by the splenectomy in all cases. 7. Postoperative complication was not occurred.

Purpose : To evaluate the usefulness of MRCP in the diagnosis of the variable causes of common bile duct(CBD) dilatation, except stone or tumor Materials and methods : Twenty-six patients(M:F=15:11, mean age; 62 years) with both MRCP and ERCP were included in this study. Dynamic MRCP(n=12) and contrast-enhanced MRI(n=10) of abdomen were also added. Dilatation of CBD, intrahepatic ducts and pancreatic duct was evaluated, including coexistence of intrahepatic ductal stone, pancreatic pseudocyst, and papillary or papillary edema. The criteria of CBD dilatation was over than 7mm(n= 21, without cholecystectomy) or 10 mm(n=5, with cholecystecto-my) in diameter on T2-weighted coronal image. Results : The mean diameter of CBD was 12.7mm without cholecystectomy(9-19 mm) and 13.0 mm with cholecystectomy(10-15mm), respectively(p 〉0.05). Cholangitis(n=11, 42.3%), chronic pancreatitis(n=8, 30.8%), stenosis of distal CBD(n= 6, 23.1%), periampullary diverticulum(n=3, 11.5%), stenosis of ampulla of Vater(n=2, 7.7%), dysfunction of sphincter of Oddi(n=2, 7.7%), acute focal pancreatitis in the pancreatic head(n=2, 7.7%), papillitis(n=1, 3.8%), pseudocyst in the pancre atic head(n = 1, 3.8%), and ascaris in CBD(n=1, 3.8%) were noted. Pancreatic duct dilatation(n=10, 38.5%) and duodenal diverticulum(n=3, 11.5%) were also seen on MRC P. On dynamic MRCP(12 patients), distal CBD was visualized in 2 patients(16.7%), which was not shown on routine MRCP. Only 1 patient(10.0%) showed papillitis with slightly enhancing papilla on contrast-enhanced MRI (10 patients). Conclusion : MRCP was thought to be helpful in the evaluation of the causes of CBD dilatation, not caused by stone or tumor, especially in the cases of stenosis of distal CBD and chronic pancreatitis, dysfunction of sphincter of Oddi on dynamic MRCP and cholangitis and pericholangitic abnormality on contrast-enhanced MRI.

Hepatobiliary scintigraphy is very sensitivity of hepatic cell and gallbladder, biliary track atresia and biliary leakage. however, Hepatobiliary scan of biliary leakage diagnosis was separated determine biliary leakage and bowl drainage bile-juice. The object of this study will determine biliary leakage and bowl drainage bile-juice to hepatobiliary scintigraphy both decubitus position in bile leakage patients. Material & Methode: 31 patients (meal 14, Femeal 17), $51.1{\pm}14.4$ years. dynamic scan acquisition 60 farme for 60 minute on supine position. and delay scan was 2 hrs, 4 hrs, 24 hrs for 5 minute on supine, both decubitus position. Both decubitus position scan was kept for 5 minutes. Efficient of Hepatobiliary Scintigraphy both decubitus position in bile leakage patients was compared leakage size, density, image of supine position and both decubitus position. Results: 23 patients for 31 bile leakage patients was checked up function image or delay image, and 8 patients was checked up bile leakage on both decubitus. anatomical leakage location was supine position very well, but both decubitus position was separated bile leakage and moving bile-juice in bowl. also, uptake (counts/pixel) average of roi and bkg was supine 5.02, left decubitus 2.08, right decubitus 2.68. No. pixels of supine ROI counted 1.91 times than left decubitus, 1.05 times than right decubitus. Conclusion: 31 patient both decubitus position, but decubitus position was separated bile juice movement in bowl leakage location. also, It was compared ROI/BKG ratio and ROI No. pixels of supine, both decubitus in 38.5% patients. And No. pixels of supine position was large 19%, 5% than left decubitus, right decubitus, And density was in low 60%, 50% than left decubitus, right decubitus. It was mean bile leakage of ROI. so, If Hepatobiliary Scintigraphy was additional both decubitus position scan in bile leakage patients, this study will be more valuable in diagnosis of bile leakage.

Purpose : Hyperbilirubinemia, jaundice and gallbladder hydrops are unusual manifestations of Kawasaki disease (KD). In this case, abdominal pain, anorexia and abdominal distension may follow eventfully. We reviewed the clinical and laboratory data to investigate the causative factors of hyperbilirubinemia in patients with KD. Methods : Two-hundred eighty two children diagnosed and hospitalized with KD were identified by searching patients' charts. Cases were included in the study if diagnosed between January 1997 and December 2004. We reviewed clinical data, age, sex, duration from the onset of fever to admission and duration from start of treatment to defervescence. Clinical and laboratory data were compared between normal (A) and hyperbilirubinemia (B) groups. Results : Thirteen patients (4.6 percent) showed hyperbilirubinemia. In the hyperbilirubinemia group, age and initial ALT value were higher than group A (P=0.003, 0.018 respectively). Duration from the onset of fever to admission and age were relative risk factors in hyperbilirubinemia (P=0.007, 0.003 respectively) in patients with KD. Conclusion : Shorter duration from the onset of fever to admission and older age group were relative risk factors of hyperbilirubinemia in patients with KD.

Background: We have previously found that intra-peritoneal lidocaine instillation before pneumoperitoneum attenuates pneumoperitoneum-induced hypertension. Whether this procedure alters patient's hemodynamic status during operation should be determined for clinical application. This study elucidated the possible mechanism of the attenuation of the pneumoperitoneum-induced hypertension by intra-peritoneal lidocaine before pneumoperitoneum. Methods: Thirty-four patients underwent laparoscopic cholecystectomy (LC) were randomly allocated into two groups. After induction of general anesthesia, 200 mL of 0.2% lidocaine (lidocaine group, n=17), or normal saline (control group, n=17) were sub-diaphragmatically instilled 10 minutes before pneumoperitoneum. The changes in systolic blood pressure, heart rate, central venous pressure, stroke volume, cardiac output, and systemic vascular resistance were compared between the groups. The number of analgesics used during post-operative 24 h was compared. Results: Systolic blood pressure was elevated during pneumoperitoneum in both groups (p<0.01), but the degree of elevation was significantly reduced in the lidocaine group than in the control (p<0.01). However, stroke volume and cardiac output were decreased and systemic vascular resistance was increased after induction of pneumoperitoneum (p<0.05) without statistical difference between two groups. The number of analgesics used was significantly reduced in the lidocaine group (p<0.01). Conclusion: These data suggest that intra-peritoneal lidocaine before pneumoperitoneum does not alter patient's hemodynamics, and attenuation of pneumoperitoneum-induced hypertension may be the consequence of reduced intra-abdominal pain rather than the decrease of cardiac output during pneumoperitoneum. Therefore, intra-peritoneal lidocaine instillation before pneumoperitoneum is a useful method to manage an intraoperative pneumoperitoneum-induced hypertension and to control postoperative pain without severe detrimental hemodynamic effects.

Background : Cell adhesion molecules knave been Implicated In the various stages of tumor progression and metastasis. ICAM-1 plays a important roles in cell-cell interactions in inflammatory and immune response of several diseases. Recently, elevated levels of sICAM-1 in circulation was reported as association with liver metastasis in gastric, Colonic, gall bladder and pancreatic cancer, with reduced survival in malignant melanoma. This study was performed to measure the sICAM-1 in patients with lung cancer and to evaluate the relations between staging of lung cancer and level of sICAM-1. Methods : Serum sICAM-1 was measured in 36 patients with lung cancer according to the pathologic types and clinical staging before therapy and in 8 controls with ICAM-1 ELISA kit. Results : Serum sICAM-1 levels were elevated in patients with lung cancer except small cell type. Also progression and metastasis of lung cancer associated with elevation of sICAM-1 levels. Conclusion : These results suggest that higher levels of serum ICAM-1 reflect the progression and metastasis of lung cancer and it may be used as a marker with diagnostic and prognostic significance.

In order to observe the infectivity, growth and development and adult morphology of Metorchis orientalis, a total of 40 chicks were experimentally infected with 100 metacercariae respectively, collected from Pseuderasbora larva. The worms of various developmental stages were recovered from chicks at 1.5, 3, 5, 7, 9, 11, 1:k and 21 days after infection, and they were prepared for morphological observations and measurements. All of the worms were found in the gallbladders of chicks, and their recovery rate was 32% in average. The growth of the body was rapid from 9 to 11 days after infection. The genital primordia appeared in 1.5 and 3-day old worms, and ovary and testes were first observed in 5-day old worms. Thereafter, genital organs gradually matured and completed up to 11 days after infection. The adult worm was leaf-like, and possessed a con- voluted tubular seminal vesicle, an ovoid ovary, a sac-like seminal receptacle, 2 lobed-testes and follicular vitellaria. Eggs were $31.9{\times}15.3{\;}\mu\textrm{m}$ in average size, ellipsoid to elliptical in shape and possessed abopercular thickenings. From the above results, it is concluded that M. orientalis grows in sigmoid pattern in chicks, and their genital organs fully matul.e between days 9 and 11. It is also confirmed that a chick is a new definitive host of M. orientalis.

Quantitative analysis of gallbladder emptying is important in diagnosis of motility disorder of gallbladder and in studies of biliary physiology. However, the normal range of gallbladder ejection fraction (GBEF) has not been determined yet and the best method for stimulating the gallbladder to contract has not been elucidated adequately. The purpose of this study was to compare the gallbladder emptying effect of the fatty meal ingestion with that of the continuous infusion of cholecystokinin (CCK) and to establish the normal GBSF values of normal subjects. Quantitative hepatobiliary scan with $^{99m}Tc-DISIDA$ after a fatty meal was performed for 22 normal healthy volunteers. Among them, 10 subjects repeated the test with a fatty meal. Again, for 7 subjects quantitative heaptobiliary scan with an infusion of CCK (sincalide) at a rate of 20 ng/kg/hr for 45 minutes was performed repeatedly. The results were as follows. 1) With a fatty meal, the mean GBEF was $89.6{\pm}8.2%$ in 22 normal subjects, and there was no difference between subjects. 2) With a continuous infusion of CCK, the mean GBEF was $62.4{\pm}16.6%$ in 7 normal subjects, and there was a significant difference between subjects(p<0.05). 3) The reproducibility of GBEF by a fatty meal was significantly higher than by an infusion of CCK (p < 0.05). 4) The mean GBEF by a fatty meal was significantly higher than that by an infusion of CCK (p < 0.05). We concluded that a fatty meal is superior to a continuous infusion of CCK for inducing gall-bladder contraction because that induces more complete emptying and the response is more reproducible and constant.
