Ascariasis symptoms penetrated into biliary tract are reported to be found much more in Korea than in foreign countries. And the present writer believes there are also many cases of biliary tract symptoms that are actually experienced but that are not reported. As a result of experiencing and nursing twenty cases of ascariasis symptoms of biliary tract, the present writer has got several conclusions, and reports them together with reference to sundry records. (1) The penetrating rate of ascariasis in male versus female was 1 to 1.5. Consequently the rate of female was higher than that of male. The highest age of the case was 67, the lowest 19, and the average age was 45.2. (2) As to symptoms, right upper quadrant abdomen pain and fat diet intolerance were the largest in number. By laboratory findings there were depressive pain on right upper quadrant abdomen in all the cases. (3) As to the location of ascariasis, choledochus occupied the largest part, and the longer illness history was, the more cases coexisting with calculus were found. (4) As to operative method, cholecystectomy and choledochotomy weres the largest in number, and choledochotomy T-tube was inserted in all cases. As to complication after operation, there were operative wound infection, excoriation through bile juice issue, etc. There were three cases of re-penetration of ascariasis and only one case of reoperation.

Pancreaticobiliary tract strictures are frequent Indications for endoscopic retrograde cholangiopancreatography(ERCP). We have investigated the brushing cytology in order to determine its efficacy for diagnosis of pancreaticobiliary malisnancies. Brushing cytology during ERCP was evaluated in 56 patients with biliary tract stricture presenting to the Catholic Hospital of Taegu-Hyosung from April 1997 to August 1999. A comparison was made between the cytologic and histologic diagnoses on 32 cases from 30 patients. A diagnosis of malignancy was establishied in 78.1%, benign in 15.6%, and inadequate in 6.3% of the cases. Statistical data on cytologic diagnoses in strictures of the bile duct were as follows; specificity and sensitivity of blushing procedure was 100% & 83.3%, respectively: sensitivity of interpretation was 89.3%: with no false positive cases and 3 false negative cases: predictive value for malignancy was 100% & 100%, respectively: predictive value for benign was 28.6% & 40%,, respectively: overall diagnostic efficiency was 84.4%. It is concluded that brush cytology is a diagnostically reliable, highly specific technique for malignant lesions encounted at ERCP, although a negative result does not rule out the diagnosis of malignancy.

This study on the biliary excretion of sulfadiazine has been established in the rats. 1. Sulfadiazine, administered intravenously to rats with ligated renal pedicles and a cannulated bile duct, rapidly appeared in the bile in high concentration. 2. Between 0-30min. and 30-60 min. after administration, the bile-to-plasma concentration ratios(B/P) of the sulfadiazine were 1. 02-2.67, 1.14-3.79 for 1mg/kg dose, 1.48-3.89, 1.30-3.81 for 10mg/kg, 1.97-4.27, 2.11-4.07 for 50mg/kg, and 1.70-4.21, 1.71-5.34 for 100mg/kg. Thus, B/P ratios at any doses of sulfadiazine greatly exceeded 1.0 at all experimental periods. 3. Furthermore, the biliary excretion of sulfadiazine was inhibited by probenecid significantly. 4. Hepatic clearance of sulfadiazine in the rats was increased from 0.515 to 1.780 ml/60 min. when the dose was raised from 1.0mg/kg to 50.0mg/kg of sulfadiazine, but at 100mg/kg, decreased to 1.250ml/60min. All these results indicate that sulfadiazine is excreted into the bile by active transport process in the rats with ligated renal pedicles and a cannulated bile duct.

Since hepatocyte clearance, leading edge parencymal transit time and biliary excretion can be evaluated separately with hepatobiliary scan using $^{99m}Tc-DISIDA$, hepatobiliary scan may be useful in differentiating intrahepatic cholestasis from extrahepatic cholestasis. Excretory liver function was analysed in 13 healthy subjects and 11 patients with clinically suspected hepatocellular disease and 9 patients with extrahepatic biliary obstruction confirmed by surgery, radiological and clinical evidence. Indices of total liver activity (% TLA), liver parechymal uptake (% LPU), heart pool clearance (% HPC) and liver-heart rate (% LHR) were calculated from time activity curve over heart and liver. Compared with healthy subjects, significant reduction (p<0.05) in total liver activity (% TLA) and liver-heart rate (% LHR) was observed in all patients group. But no useful indices was demonstrated in differentiating hepatocellular disease from extrahepatic biliary obstruction.

Metabolite identification and urinary and biliary excretion of the new fluoroquinolone antibacterial agent DW116 [1-(5-fluoro-2-pyridyl)-6-fluoro-7-(4-methyl-1 -piperazinyl)-1, 4-dihydro-4-oxoquinoline-3-carboxylic acid, hydrochloride] after oral administration have been studied in Sprague-Dawley rats. The excretion kinetics were monoexponential. Most of the drug was eliminated via the hepatic and renal routes. Mean renal clearance of DW116 was 73.4 ml/hr/kg and mean biliary clearance was 83.8 ml/hr/kg. The major metabolite excreted in the bile was identified as the glucuronide ester of the parent drug using base-hydrolysis of the conjugate metabolite followed by co-HPLC with standard compound, $^{19}$ F-NMR and LC-MS methods. The glucuronide conjugate was also found in urine. The mean urinary recoveries of free and total (free plus glucuronide ester) DW116 were $28.6{\pm}2.7% $and $36.4{\pm}1.8%$ of the administered dose and the corresponding biliary recoveries were $14.4{\pm} 5.5%$ and $37.0{\pm}7.6%$, respectively.

This study characterized the effect of liver injury produced by hepatotoxicants on the biliary and urinary excretion of acetaminophen(AA) metabolites. Liver damage was produced in male S.-D. rats, 24 hr after dosing with carbon tetrachloride(4CCl_4,$ 0.75 mι/kg, ip) or thioacetamide(TA, 200 mg/kg, ip), or 16 hr after administration of cadmium chloride(4CdCl_2,$ 3.9 mg/kg, iv). Liver damage without renal injury was confirmed by measuring serum enzymes, creatinine and BUN levels as well as by histopathological examination. AA and its metabolites were measured for 3 hr by HPLC in rats injected iv with 1 mmo1/kg of AA. The excreted amounts of AA-glucuronide into bile were reduced to 60~70% of control rats by hepatotoxicants, but did not change urinary excretion of AA-glucuronide and AA-sulfate. Treatments with $CCl_4,\; CdCl_2$ and TA decreased the total (biliary plus urinary) excretion of thioethers of AA(30~50% of control), suggesting that these toxicants decrease cytochrome P-450-mediated toxification of AA. However, treatments of $CdCl_2$and TA markedly enhanced the excretion of AA-mercapturate into urine. Thus, 4CdCl_2$ and TA not only influence the formation of AA-glutathione, but may also alter the excretory routes (i.e. bile and urine) for the elimination of AA-metabolite.

We investigated metabolism and carcinogenesis in livers of Sprague-Dawley rats fed juices and pelleted diets containing Korean native plants petasites japonicus Maxim by evaluating cell localization and expression of cytochrome P450s and GST-P. Anti-cytochrome P450s application in liver sections revealed three to four times increased expression of cytochrome P450E1 immunoreactivity in degenerative hepatocytes when compared to histologically normal hepatocytes. Anti-GST-P in showed positive pren plastic foci as well as in individual hepatocytes randomly scattered throughout all liver sections examined. Additionally GST-P was evident in proliferative endothelial cells and biliary epithelial cells in exposed rat livers. These results suggested that the increased level of cytochrome P4502E1 in affected hepatocytes was a direct consequence of Petasites japonicus toxicity. Further immunoreactivity to anti-GST-P in hepatocytes endothelial cells and biliary epithelial cells indicated a possible preneoplastic effects of Petasites japonicus in Sprague-Dawley rat.

Aim: The incidence of biliary tract cancer (BTC) is many-fold higher for American Indians (AI) relative to non-Hispanic whites (NHW). Neither gallstones nor genetics can account for this difference. There is speculation that certain fatty acids in bile may play a role in preventing BTC. Since diet may influence composition of bile, we compared the dietary intakes of urban AI and NHW adult women in New Mexico. Methods: Design, a cross-sectional study of the diets of lactating AI and NHW women was conducted. Setting, the University of New Mexico Hospital. Participants, healthy lactating women 18 to 39 years of age were recruited. Main outcome measures, a three-day diet record for each participant was analyzed. Results: The AI women consumed less calcium (p = 0.04) and significantly less short and intermediate chain-length fatty acids (C4-C12), but nearly twice as much proinflammatory arachidonic acid as the NHWs (p <0.01). The intake of dairy products by AI women was less than NHW women (p = 0.01) while the intake of processed meat products was higher (p <0.01). Conclusion: Dietary factors may account for the difference in the risk of BTC between AI and NHW women.

Background: Because of the relative rarity of biliary tract cancers (BTCs), defining long term survival results is difficult. In the present study, we aimed to evaluate the survival of a series of cases in Turkey. Materials and Methods: A totally of 47 patients with billiary tract cancer from Mersin Goverment Hospital, Acibadem Kayseri Hospital and Kayseri Training and Research Hospital were analyzed retrospectively using hospital records between 2006-2012. Results: The median overall survival was $19.3{\pm}3.9$ months for all patients. The median disease free and overall survivals were $24.3{\pm}5.3$ and $44.1{\pm}12.9$ months in patients in which radical surgery was performed, but in those with with inoperable disease they were only $5.3{\pm}1.5$ and $10.7{\pm}3.2$ months, respectively. Conclusions: BTCs have a poor prognosis. Surgery with a microscopic negative margin is still the only curative treatment.
