Purpose : The purpose of this study is to find out the diagnostic significance of serum bile acid on total parenteral nutrition induced cholestasis in premature infants. Methods : Infants without cholestasis were classified into postnatal days and each change of serum bile acid was measured and analyzed. Also, the serum direct bilirubin, serum bile acid, ${\gamma}$-glutamic acid transferase, and alkaline phosphatase of premature infants with total parenteral nutrition induced cholestasis were measured for comparison and analysis of their correlation. Results : Changes of serum bile acid analysis after birth showed no significant difference between boys and girls, between premature infants and term infants without cholestasis. Serum bile acid levels are constant after two weeks after birth in neonates without cholestasis. In premature infants with total parenteral nutrition induced cholestasis, the increase of serum direct bilirubin over 2 mg/dL was $34.9{\pm}18.3$ days after birth, and the increase of serum bile acid was $28.1{\pm}18.3$ days. Its increase was about 1 week faster than serum direct bilirubin, however, there was no statistical significance(P=0.114). Comparing analysis of serum bile acid, ${\gamma}$-glutamic acid transferase, and alkaline phosphatase, serum bile acid showed the highest correlation to serum direct bilirubin(r=0.487, P=0.000). Conclusion : Serum bile acid is an important parameter of total parenteral nutrition induced cholestasis in premature infants and will be useful for early diagnosis and treatment.

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.

We investigated the effect of a green seaweed Capsosiphon fulvescens extract (CFE) on the serum, liver tissue, and fecal cholesterol levels in rats. Male Sprague-Dawley rats (four weeks old) were given on of three diets for four weeks: basal, high cholesterol, and CFE, The total serum and liver tissue cholesterol levels in the CFE group were significantly decreased compared to those in the cholesterol group. The CFE group showed increased amounts of feces, total fecal bile acid and dietary fiber as compared to basal and cholesterol group. Hematoxylin and eosin staining revealed fat droplets in the livers of the rats in the cholesterol group; however, a decreased number of droplets was observed in the rats fed the CFE diet. Our results suggest that CFE supplementation may improve lipid metabolism, by controling serum and liver tissue cholesterol levels, and by increasing the total amounts of bile acid, dietary fiber and cholesterol excretion in feces.

Purpose: The aims of this study are to measure the serum levels of fat soluble vitamins (vitamin A and D) from bile duct ligated rats, and to evaluate the effect of oral bile acids administration to facilitate absorption of fat soluble vitamins. Methods: We measured serum ALT, total bilirubin, vitamin A, and vitamin D of Sprague-Dawley rats 1 week before and 4 weeks after experimental bile duct ligation. Rats were consisted with 3 groups. Group 2 had been fed bile acids and group 3 ursodeoxycholic acid after operation for 4 weeks. Multi-vitamin was given to all groups. Results: 1) Base line (mean value before duct ligation): ALT 74.2 IU, total bilirubin 0.26 mg/dL; vitamin D 13.01 ng/mL vitamin A $0.87\;{\mu}g/mL$, total bile acids $25.16\;{\mu}mol/L$. 2) Four weeks after ligation: ALT 100.7 IU, total bilirubin 2.58 mg/dL; vitamin D 7.89 ng/mL vitamin A $1.37{\mu}g/mL$, total bile acids $278.22\;{\mu}mol/L$. 3) 4 weeks after ligation, each group (group 1, group 2 and group 3) showed vitamin D (7.62, 8.10 and 7.99) ng/mL, vitamin A (1.68, 1.06 and 1.33) ${\mu}g/mL$, total bile acids (233.17, 345.80 and 268.57) ${\mu}mol/L$, which were statistically not significant. Conclusion: Serum level of vitamin A is increased after bile duct ligation although vitamin D is decreased. Oral administration of bile acids does not affect the serum levels of vitamin A and D in bile duct ligated rats.

In oriental folk medicine, Artemisia messes-schmidiana var viridis(Compositae) has been used for jaundice, hepatitis, diuretic and liver cirrhosis etc. 1-naphthylisothiocyanate(ANIT) has been used for more than 20 years as a model compound to study mechanisms of intrahepatic cholestasis in laboratory animals as rat and mouse. Various biochemical and morphological changes including biliary epithelial and parenchymal cell necrosis occur in the liver of animals treated with ANIT. The purposes of present study are to examine pharmacological effects of Artemisia messes-schmidiana var viridis water extract(AMWE) on alterations of secretion volume and total bile acids level in bile juice, and that of serum AST, ALT, ALP, bilirubin, and glucose levels in rat. AMWE stimulated bile secretion and recovered ANIT-induced cholestasis. Bile acid concentrations increased to more than 60% compared with normal by ANIT, which were returned toward normal value with AMWE treatment. Serum AST and ALT activities were increased by ANIT and yet which were significantly decreased with AMWE treatment. In addition, this effect was apparent in AMWE pretreatment group. Serum glucose levels were increased with AMWE and ANIT, while were decreased compared with control in AMWE posttreatment group. Increased serum total bilirubin contents and ALP activities by ANIT were significantly decreased with AMWE posttreatment. In conclusion, AMWE exerted bile acid-independent choleresis effect and then improved to normal conditions ANIT-induced cholestatic syndromes. Also, AMWE have protective and regenerative effect of hepatocytes in rat.

This study investigated the effects of polymannuronate feeding on cholesterol levels of serum, liter tissue, and feces in rats. After one week of general diet feeding, four week old S.D. rats were fed basal group, cholesterol diet group (1$\%$ cholesterol), and rolymannuronate diet group (1$\%$ cholesterol,5$\%$ polymannuronate). The total cholesterol levels in the serum and liver tissue was significantly decreased in the polymannuronate diet group. The polymannuronate diet group showed increased amounts of feces, total fecal bile acid and dietary fiber contents compared to basal diet group and cholesterol diet groups. Also, the histology of liver showed serious localized fat drops in the cholesterol diet group, but the polymannuronate diet group showed fewer localized fat drops. These results suggest that feeding of polymannuronate improves the lipid metabolism profile of rats by changing the serum and liver tissue cholesterol levels with increased level of the total bile acid, total dietary fiber and total cholesterol level in the feces.

The effect of Artemisia princeps var orientalis(mugwort) and Circium japonicum var ussuriense (Unggungqui) on lipid metabolism was examined . Thirty rats of 5 experimental groups were fed with a diet containing 1% cholesterol and 0.25% sodium cholate(control diet) and 5% plant powder or its water soluble extract(experimental diet) for 4 weeks. The activity of enzymes related to liver function, lipid components of liver and principle organs, and fecal steroids were assayed. The activity of enzymes was significantly lower in the unggungqui and mugwort powder diet group than in control. Liver total cholesterol , free cholesterol, and triglyceride levels were significantly lower in Unggungqui powder diet groups that in the control. The concentrations of total cholesterol , triglyceride and phospholipid in heart and kidney were comparatively low in the Unggungqui powder diet groups. In each plant powder diet group, the values of serum bile acid were significantly lowe ran the fecal steroid excretion was higher than in the control and the extract diet groups.

Any infant noted to be jaundiced at 2 weeks of age should be evaluated for cholestasis with measurement of total and direct serum bilirubin. With the insight into the clinical phenotype and the genotype-phenotype correlations, it is now possible to evaluate more precisely the neonate who presents with conjugated hyperbilirubinemia. Testing should be performed for the specific treatable causes of neonatal cholestasis, specifically sepsis, galactosemia, tyrosinemia, citrin deficiency and endocrine disorders. Biliary atresia must be excluded. Low levels of serum gamma-glutamyl transferase in the presence of cholestasis should suggest progressive familial intrahepatic cholestasis type 1, 2, or arthrogryposis- renal dysfunction-cholestasis syndrome. If the serum bile acid level is low, a bile acid synthetic defect should be considered. Molecular genetic testing and molecular-based diagnostic strategies are in evolution.

Diagnosis of cholangiocarcinoma (CCA) is difficult when patients do not show jaundice. The aim of this study was to examine the feasibility of using the total serum bile acid (TSBA) level as an aid for the diagnosis of CCA in patients without jaundice. For this purpose, TSBA of the following groups were measured using a Beckman Synchron CX4 clinical chemistry analyzer: 60 cases of CCA with total serum bilirubin ${\leq}2mg/dL$ (low total bilirubin group, LTB); 32 cases of CCA with total serum bilirubin >2 mg/dL (high total bilirubin group, HTB); and 115 healthy controls. Liver function parameters such as serum cholesterol, albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were also examined. The results showed that the TSBA of both LTB and HTB groups of the CCA patients were significantly higher than that of the healthy controls. Also, significant correlation was observed between TSBA and total bilirubin levels in the HTB group of CCA patients. However, no such correlation was seen in the LTB group. The cut-off value of TSBA was determined for the LTB group of CCA patients using the receiver operating characteristic curve analysis, and it was $6.05{\mu}mol/L$ with the sensitivity and specificity of 46.7% and 84.4%, respectively. In addition, the ALP level was correlated well with the TSBA level and ALP in HTB group was significantly higher than that of LTB group. Moreover, the combination of high TSBA and high ALP levels gave higher specificity up to 97.4%. TSBA might be useful for the diagnosis of CCA patients without jaundice.

Effects of water-soluble extract from roasted-chicory root on the cholesterol metabolism in rats fed cholesterol diet were investigated. Sprague-Dawley rats received a hypercholesterolemic diets without (control group) or with 5.0% water-soluble extract from roasted chicory root for 2 weeks. Roasted chicory extract group showed significantly higher body weight gain and food intake compared with the control group. The concentrations of total cholesterol and LDL+VLDL cholesterol in serum were significantly lower in rats fed roasted chicory extract diet. However, HDL-cholesterol concentration, and atherogenic index were not significantly affected by the dietary roasted chicory extract. Fecal net weight, fecal cholesterol, and bile acid excretion were significantly higher in the chicory extract group. The results suggest that the hypocholesterolemic effect in rats fed roasted chicory extract may be caused by an alteration in the absorption of cholesterol by an increase in the fecal excretion of cholesterol and bile acid.
