  • Effects of phenobarbital pretreatment on the pharmacokinetics of enterohepatic recirculating griseofulvin were investigated by comparing normal to bile duct cannulated rats and also the effects of enhanced endogeneous bile flow on the absorption of griseofulvin were studied by means of in situ recirculation method in phenobarbital-pretreated rats. Phenobarbital was administered orally for five days at the dose of 75 mg/kg/day. The influence of phenobarbital pretreatment on the absorption rate constant, area under the plasma concentration-time curve, maximum plasma concentration of orally administered griseofulvin was not found in bile duct cannulated rats. Decreased absorption clearance and apparent partition coefficient of griseofulvin in accordance with the amount of endogeneous bile juice seemed to be due to the decrease of thermodynamic activity of griseofulvin as bile forms the micelle with griseofulvin.

  • A 10 year old boy was admitted with blunt abdominal trauma by bike handle injury. The patient was operated upon for a generalized peritonitis due to pancreaticoduodenal injury. On opening the peritoneal cavity. complete transection of distal end of common bile duct and. partial separation between pancreas head and second portion of duodenum were found. Ligation of the transected end of the common bile duct. T-tube choledochostomy, and external drainage were performed. A pseudocyst was found around the head portion of the pancreas on the 7th postoperative day with CT. An internal fistula had developed between the pseudocyst and ligated common bile duct. The pseudocyst was subsided after percutaneous drainage. In the case of the undetermined pancreatic injury, percutaneous external drainage can be effective in treating the traumatic pancreatic pseudocyst in a pediatric patient.

  • Cholic, ursodesoxycholic, chenodesoxycholic, desoxycholic and hydesoxycholic acids were dissolved in the propylene glycol to make solution and then above solution of cholanic acids on bile secretion was investigated by injection those solutions into small intestine of rabbits and albino rats. The cholates in bile juice from rabbits injected with cholic acid were remarkably increased and therefore it exhibited a typical choleretic action. In view of pharmacological point, desoxycholic acid is considered as superior hydrocholeretic agent, and ursodesoxycholic and chenodesoxycholic acids have similar effect in decreasing order. However, the effect of bile secretion by hyodesoxycholic acid was almost negligible as that by propylene glycol administered. The cholate content in the bile juice from albino rat was increased by cholic and desoxycholic acids in decreasing order: i.e., they exhibited choleretic action. In the case of ursodesoxycholic and chenodesoxycholic acids, the concentration of cholate was slightly increased in bile juice from the rat, so that these cholates showed a weak choleretic action. While total output of bilirubin was increased by chenodesoxycholic acid, the other cholanic acid showed no effect in the rabbit.

  • Bifidobacteria are a prototype probiotic, which normally inhabit the intestinal tract of humans. In the present study, four species of Bifidobacterium isolated from the feces of infants were characterized. The tolerance for acid or bile salt, autoaggregation, and antibiotic resistance of the bacteria were examined. The four species were resistant to low pH, bile salts, and up to 3% bile acid. Autoaggregation rates were as high as 90%. The bacteria were consistently resistant to gentamicin, kanamycin, streptomycin, ciprofloxacin, and nalidixic acid. Due to their tolerance to environmental factors like acid and bile salts, B. longum MG723, B. breve MG729, B. bifidum MG731, and B. animalis subsp. lactis MG741 are potentially valuable as probiotics and may be useful for industrial application.

  • Cholestatic liver injury results from the accumulation of toxic bile salts within the liver. The aim of the present study is to elucidate the changes in expression and cellular localization of apoptosis related proteins in the liver of bile duct-ligated (BDL) rat. Extrahepatic cholestasis was induced by double ligation of the common bile duct and cut between the ligatures. Animals were sacrificed at day 3 and at week 1, 2, 4, 6, and 8 after BDL. The number of TUNEL positive cells was increased significantly after 3 days of BDL, decreased over 2 weeks and remained constant thereafter. Fas expression was not changed and activation of caspase 8 did not occur. Fas immunoreactivity was exclusively observed in the cytoplasm of hepatocytes, indicating that Fas expressed in rat hepatocytes is a soluble form. Hepatocyte apoptosis was associated with Bax expression, which showed a peak at day 3 and decreased over time gradually. Immnunostaining of Bax was observed in hepatocytes and bile duct epithelial cells (BEC) of control and BDL rats. Bcl-2 was increased over time in BDL rats. These results suggest that apoptosis of hepatocytes in BDL rats is independent of Fas and controlled by Bax expression.

  • Extrahepatic bile duct injury is commonly associated with hepatic, duodenal, or pancreatic injuries, and isolated extrahepatic bile duct injury is rare. We report a patient who presented with an isolated extrahepatic bile duct injury after blunt trauma. A 50-year-old man was referred to our hospital after having suffered a fall down injury. His laboratory findings showed hyperbiliribinemia with elevated aspartate aminotransferase and alanine aminotransferase level. Initial abdominal computed tomography (CT) showed a mild degree of hemoperitoneum without evidence of abdominal solid organ injury. On the 3rd day of hospitalization, the patient complained of dyspnea and severe abdominal discomfort. Follow-up abdominal CT showed no significant interval change. Owing to the patient's condition, Emergency laparotomy revealed a large amount of bile-containing fluid collection and about 1 cm in size laceration on the left lateral side of the common hepatic duct. Primary repair of the injured bile duct with T-tube insertion was performed On postoperative day (POD) 30, endoscopic retrograde cholangiopancreatography showed minimal bile leakage and endoscopic sphincteroplasty and endoscopic retrograde biliary drainage were performed. On POD 61, the T-tube was removed and the patient was discharged.

  • Administration of milk and fermented milks produced from indigenous dadih lactic acid bacteria on serum lipids and bile acids, fecal bile acids and microflora was estimated in hypercholesterolemic rats. Anaerobic lactic acid bacteria decreased and coliforms increased in the feces of the control group; however, the number of fecal lactic acid bacteria remained unchanged when rats were administered milk and fermented milks. Only fermented milk made from Lc. lactis subsp. lactis IS-10285 significantly reduced serum total cholesterol, LDL cholesterol and total bile acids. Milk and fermented milks did not influence the HDL cholesterol. Triglyceride and phospholipid levels were significantly lower in the rats fed fermented milk of Lc. lactis subsp. lactis IS-10285 than rats fed milk and fermented milk of Lc. lactis subsp. lactis IS-29862, but not significantly different from the control group. Hypocholesterolemic effect of Lc. lactis subsp. lactis IS-10285 was attributed to its ability to suppress the reabsorption of bile acids into the enterohepatic circulation and to enhance the excretion of bile acids in feces of hypercholesterolemic rats.

  • Stabilization of liposomes against degradation by bile salts has been investigated in order to develop a liposomal model system for oral drug delivery. Two polysaccharides, amylopectin (AP) and chitin (CT), were employed to coat both empty liposomes and bromthymol blue (BTB)-encapsulated liposomes by adsorption-coating techniques. Turbidity changes and BTB-release characteristics in pH 5.6 buffer solutions with or without bile salts, sodium cholate and sodium glycocholate, were observed to compare the differences between uncoated liposomes and polysaccharide-coated liposomes. Initial turbidities of both uncoated and polysaccharide-coated liposomes in buffer solution were kept constant within 3% range during 4 hours of experiments. But they were decreased in a different manner in bile salts-containing buffer solutions, showing 10% or less decrease for polysaccharide-coated liposomes and 25% or more decrease for uncoated liposomes. BTB release from uncoated liposomes has been greatly increased upto 90% after 4 hours in bile salts-containing buffer solution, which is a clue for breakdown of liposomal vesicles. However, polysaccharide-coated liposomes showed the controlled-release pattern which is proportional to square-root of time, followed by around 50% release for the same time period. Consequently, it is possible to conclude that these polysaccharide-coated liposomes might be an available system for oral delivery of a drug which is unstable in gut environment.

  • Fucoidan from sea tangle (Laminaria japonica) was isolated by hot water extraction, and partially purified. The in-vitro glucose and bile acid retarding effects of the partially purified fucoidan were investigated. Fucoidan exhibited 27.06$\sim$21.42% of retarding index for glucose and 33.50$\sim$27.02% of retarding index for bile acid during in vitro dialysis experiment for 2 hours. These retarding effects on glucose and bile acid diffusion was considered as a relatively good or very good, suggesting the prevention from diabetes and arteriosclerosis of some extent.

  • This study was carried out to isolate and characterize the Lactobacillus plantarum with bile salt deconjugation activity that was isolated from Kimchi. Some isolates were selected and identified as L. plantarum by 16S rRNA gene sequence and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis of whole cell protein patterns. They were assayed to determine their capacities to express bile salt hydrolase (BSH) activity. Among the identified strains, L. plantarum CIB 001 showed the highest level of BSH activity. Then, resistance to gastric acidity and bile condition were analyzed for further characterization. This strain was able to maintain viability for 1h at pH 2.0 and to survive in a MRS (deMan, Rogosa, and Sharpe) broth with 1.0% of bile acids. L. plantarum CIB 001 would potentially be useful in the food industry as probiotics.
