Effect of sodium taurodeoxycholate (TDC) infused intravenously on the pharmacokinetics of methylene blue (MB) was studied in the rat to investigate the role of ion-pair complexation in the body on drug elimination and disposition. Distribution volume (Vd) of MB was increased significantly (p< 0.05) by TDC infusion. Considering together with the fact that apparent partition coefficient (APC) of MB between phosphate buffer (pH 7.4) and n-octanol was increased markedly by TDC, the increase in Vd seemed to be the result of decreased polarity of MB by ion-pair formation with TDC. But total body clearance (CLt) and biliary excretion clearance (CLbil) of MB were not increased significantly by TDC.

This study was conducted to investigate the effect of nondigestable substances and calcium such as oligosaccharide, agar, saponin, tannin and calcium on the reduction of lipid status in rats fed high fat diet. In order to make the observation, the lipid content in plasma, liver and the feces, and bile acid excretion were measured of r 4 weeks. the results obtained from this research are as follows. Concentration of total lipid in plasma seemed highest in the control group and were significantly lower in groups oil-gosaccharide, agar and calcium-tannin, compared to the control group. Concentration of total cholesterol in plasma was significantly lower in groups oligosaccharide, agar, calcium and calcium-saponin, compared to the control group. The improvement in lipid status seems to be insignificant with oligosaccharide, showed increase in total bile acids excretion in feces and decrease in total cholesterol in plasma, compared to the control group. These evidence seems to indicate improvement of the plasma lipid status by calcium and agar supplementation.

A rabbit farm reared about 500 New Zealand White in Kwangju city was occurred Eimeria stiedae infection. Morbidity and cumulative mortality were more than 39% and 14%, respectively, from May, 1997 to March, 1998. Most of cases with severe diarrhea were belong to younger than 2-month old. In necrospy, there were multifocally white nodules with about 1-5mm in diameter on the liver surface and dark greenish mucous exudate in intestinal lumen. Main microscopic lesions included marked hyperplasia of the bile duct epitheilia containing different developmental stages of Eimeria stiedae and inflammatory cell infiltration, and the degeneration of small intestinal epithelia. Many oocysts of Eimeria stiedae were detected in the intestinal contents and epithelia, the feces, the bile juice, the bile duct and the liver.

This study was designed to determine whether dietary glutinous barley (GB) affects lipid metabolism in middle-aged rats previously fed a high-fat diet. To induce obesity, 20 male 9-month-old Sprague Dawley rats were raised for 1 month on a diet containing 20%(w/w) lipid. The rats were allocated to 1 of 2 groups of 10 rats each and for the subsequent 2 months were fed an 8%(w/w) lipid diet containing well-milled rice (WMR) or GB powder. Rats fed the GB diet had significantly lower concentrations of plasma triglyceride, plasma total cholesterol, and liver cholesterol than rats fed the WMR diet. Fecal excretions of triglyceride and bile acids were significantly greater for the GB group than for the WMR group. In conclusion, dietary GB has positive effects on lipid metabolism: it decreases plasma cholesterol concentration by increasing fecal excretion of bile acids.

Twelve strains of Lactobacillus acidophilus isolated from feces of human or animal sources were tested for probiotic properties such as cholesterol assimilation, bile and acid tolerances, and CLA production. Although the cultures showed some variation with respect to each test, the 12 strains could be classified into 3 groups based on their ability to assimilate cholesterol. The cholesterol assimilation showed positive correlation with bile tolerance and negative correlation with acid tolerance. The cholesterol assimilation of L. acidophilus strains may not be related to the deconjugation activity, but may in fact be attributed to its bile tolerance. CLA production by lactic acid bacteria (LAB) exhibited a wide variation that ranged from 2.69 to 7.64 mg/g fat. CLA production of Bifidobacterium longum ATCC 15707 was the highest among the LAB tested, but there was no evidence for differences in CLA production between genus and species.

This study was undertaken to determine the effect of yellow and black soybeans on plasma and hepatic lipid composition and fecal lipid excretion in Sprague Dawley rats. Animals were fed with diets containing 52% yellow soybean, 50% black soybean, or 20% casein for 7 weeks. Feeding efficiency was significantly increased in the animals fed soybeans(p<0.05). Plasma cholesterol concentration was significantly lowered in the group fed yellow soybean compared with black soybean and casein-fed control (p<0.05). Hepatic triglyceride concentration was significantly lowered in soybean groups compared with casein-fed control(p<0.05), whereas hepatic cholesterol concentration was not affected by diet treatments. Soybean feeding significantly increased fecal weight, triglyceride and bile acid contents compared with casein feeding(p<0.05). It is concluded that soybean feeding in rats affects plasma and hepatic lipid levels by increasing the excretion of triglyceride and bile acids.

The effects of Malloti Cortex Water Extract (MCWE), bergenin (isolated as an active component from MCWE), and acetylbergenin (synthesized from acetylation of bergenin) on the liver fibrosis induced by bile duct ligation (BDL) in rats. We studied hydroxypro1ine (HYP) as a marker of collagen accumulation in the liver, alanine aminotransferase (s-ALT), aspartate aminotransferase (s-AST), and alkaline phosphatase (s-ALP) as serum markers of liver cell damage induced by BDL, MCWE, bergenin, and acetylbergenin decreased towards normal the accumulated levels of HYP in the liver and the elevated serum levels of s-ALT, s-AST and 5-ALP. The results indicate that MCWE, bergenin, and acetylbergenin ameliorated the liver damage induced by BDL in rats.

Among several diagnostic tools for clonorchiasis (Clonorchis sinensis infection), radiologic examinations are commonly used in clinical practices. During the 2 past decades, many reports regarding imaging findings of clonorchiasis were introduced. The basic imaging finding of clonorchiasis is diffuse dilatation of the peripheral intra-hepatic bile ducts, without dilation of the large intrahepatic or extrahepatic bile ducts. By this finding, however, active clonorchiasis cannot be differentiated from cured infection. Some recent radiologic studies suggested specific findings of active clonorchiasis. Besides direct demonstration of worms, increased periductal echogenicity on sonography and periductal enhancement on dynamic contrast-enhanced CT or MR imaging possibly represent active clonorchiasis. Those images of the liver clonorchiasis are known to be correlated with worm burdens (EPG counts) in their frequency and also severity. The images of cholangiocarcinoma associated with clonorchiasis show both the tumor with obstruction images and diffuse dilatation of the peripheral intrahepatic bile ducts. Radiological images can be a good practical alternative diagnostic method of clonorchiasis.

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.

Echinococcosis is a disease caused by the Echinococcus species that parasitizes in humans. Alveolar echinococcosis (AE) which is caused by Echinococcus multilocularis is harmful to humans. AE mainly occurs in the liver and can be transferred to retroperitoneal lymph nodes, lung, brain, bone, spleen and other organs through lymphatic and blood vessels. Cholangiocarcinoma can occur in of the intrahepatic and extrahepatic bile ducts and is more common in the hilar. We reported a case of hilar bile duct alveolar echinococcosis which was originally misdiagnosed an cholangiocarcinoma.
