  • The purpose of this study is to analyse clinical impact of specific MRI findings in liver in patients of long-term survivors after Kasai portoenterostomy (KPE). Twenty-eight patients who were underwent KPE were followed up more than 5 years. Macro-regenerative nodule (MRN) and beaded-duct dilatation (BDD) were considered as important findings in liver MRI. The association between these findings in MRI and clinical indicator, serum bilirubin level and history of cholangitis were evaluated. Sixteen patients (57.1%) were shown MRN in liver MRI. Therewere 14 patients(50%) whose MRI showed BDD. Serum total and direct bilirubin were 3.6 mg/dL and 1.8 mg/dL respectively in positive MRN group whereas 1.4 mg/dL and 0.7 mg/dL in negative MRN group (p = 0.427). Serum total and direct bilirubin level were 4.2 mg/dL and 2.1 mg/dL in patients with BDD negative group compare to 1.1 mg/dL and 0.5 mg/dL in BDD positive group (p = 0.281). The odds ratio to have cholangitis in the patient with MRN was 2.3 and 0.53 in patient with BDD in their MRI findings. MRN in liver MRI may suggest high bilirubin level and more chance to have cholangitis, but the findings of BDD may related to low bilirubin level and less change to have cholangitis.

  • In the present communication, the results will be reported on a clinical study of how well scintigraphic visualization of the hepatobiliary elements and several commonly used clinical liver function tests correlate each other in various diseases oft hepatobiliary system. The demonstrability of the biliary tract, gallbladder (GB) and duodenum was rather closely paralleled to serum bilirubin level and less closely to alkaline phosphatase and rather poorly to SGOT and SGPT. The biliary tree could not be visualized scintigraphically when bilirubin exceeded 10.5mg/dl. The usefulness of Tc-99m EHIDA [N-(2,6-diethylacetanilido) iminodiacetic acid, made by Amersham, England] hepatobiliary scintigraphy (Tc EHIDA HBS) in settling diagnostic controversy and ambiguity raised by oral cholecystography, intravenous cholangiography and ultrasonography in many hepatobiliary diseases is well known. The purpose of this investigation was to semiquantitatively evaluate the scintigraphic demonstrability of the hepatobiliary tract, GB and duodenum following intravenous injection of Tc-99m EHIDA in normal subjects and in patients with a disturbed liver function from various hepatobiliary diseases. The hepatobiliary scintigraphy was performed in 10 normal subjects and 39 patients with various hepatobiliary diseases (Table 1) at the Dept. of Radiology, St. Mary's Hospital Catholic Medical College, Seoul, Korea during 2 years period from September 1979. Scintigraphic examination was started at end of 3 minutes after intravenous injection of Tc-99m EHIDA in the amount of $50{\mu}Ci/kg$ and was continued until after 30 minutes at 5 minutes interval. The imaging was usually terminated when the tracer could be seen in the duodenum. Late scintigrams were obatained at 1 1/2, 3, 4 and 6 hours when reeded. Scintigrams were analyzed in terms of promptness and clarity of visualization of the biliary tree, GB and duodenum and demonstrability of these anatomical landmarks was correlated with the values of liver function tests. The demonstrability of the common hepatic duct, common bile duct, GB and duodenum was closely paralleled to the level of serum bilirubin when it is less than 10.5 mg/dl as shown in figure 1. However when the bilirubin exceeded 10.5 mg/dl the time of visualization between protracted reaching a flat curve or plateau around 10.5 mg/dl. The biliary tract could not be visualized when the bilirubin was higher than 10.5 mg/dl. The correlability between scintigraphic demonstration and serum alkaline phosphatase was less strong and between scintigraphic demonstration and SGOT and SGPT was rather poor. The present clinical study confirmed the usefulness and limitation of Tc-99m EHIDA hepatobiliary scintigraphy in visulizing and diagnosing the biliary system and duodenum when radiogrpahy and ultrasonography failed to provide useful informations. Scintigraphy was very helpful in the diagnosis of neonatal hepatitis, biliary atresia, cholecystitis and extrahepatic biliary obstruction. The hepatobiliary system and duodenum were visualized when serum bilirubin level was less than 10.5 mg/dl, SGOT 135 units, SGPT 114 units and alkaline phosphatase 52.2 KAU.

  • 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.

  • Methanolic extract of Cassia tora leaves was evaluated for its hepatoprotective activity in rats by inducing hepatotoxicity with paracetamol (acute model). The extract at a dose of 400 mg/kg orally exhibited significant protective effect by lowering the serum levels of transaminase (SGOT and SGPT), bilirubin, and alkaline phosphatase (ALP). The effects produced were comparable to that of a standard hepatoprotective agent.

  • Direct photoisomerizations of benzalpyrrolinones yield the corresponding E-isomers via a singlet state, since no effect of oxygen on the reaction rates was observed. The Z-oxodipyrromethene was photoisomerized to the E-isomer in a degassed system. In an aerobic system the oxodipyrromethene 3 was photoisomerized at the early stage of the reaction and photooxygenated slowly at latter stage of the reaction. For bilirubin, other (possibly Z ${\to}$ E) than self-sensitizing $^1O_2$ reaction should have occurred because of the lack of a solvent effect on the self-sensitized photooxidation reaction rate at the early stage.

  • This paper presents a portable and compact optical device which can conveniently be used to perform a functional analysis of human liver function. The proposed system employed red/green LEDs, as a light source, and CMOS image sensor, which is commonly used in cellular phones. With this system, several blood serum samples have been evaluated for liver functional analysis by measuring light absorption level through the blood serum samples depending on aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin concentration. The light absorption through the blood serum samples containing AST, ALT, or total bilirubin can provide their concentrations. The green light absorption is more sensitive to the concentration of AST or ALT, and the red light absorption is more sensitive to the total bilirubuin concentration. Additional calibration steps were performed by using a MATLAB program in order to eliminate the light scattering effects from the extraneous particles existing in each blood serum sample. From the blind test, three standard light intensity curves through each enzyme have been obtained and the enzyme concentration values have been compared to those obtained from a commercially available biochemistry analyzer (Toshiba 200 FR). The average percent difference in the obtained concentrations from two systems for AST, ALT, and total bilirubin concentration came out to be 7.79%, 7.98%. and 7.56%, respectively, with the adjusted coefficient of determination (R2) higher than 0.98. This system can possibly lead to a low-cost and simple system that can be used as a point-of-care (POC) system in a condition without advanced equipments.

  • This study was performed to investigate hepatoprotective effect of rutin on acute hepatic damage induced by carbon tetrachloride in rats. Twenty-four male Sprague-Dawley rats were randomly divided into four groups; normal control group, $CCl_4$ control group, two rutin treatment groups (rutin 200+$CCl_4$ and rutin 400+$CCl_4$). Dissolving vehicles were applied to the rats in the normal control group. The rutin was administrated to the rats in rutin 200+$CCl_4$ and rutin 400+$CCl_4$ groups at the levels of 200 mg/kg and 400 mg/kg, 3 consecutive days orally, with 24 hours interval before inoculating $CCl_4$. $CCl_4$ was intraperitoneally administered an hour after the last treatment of rutin to the rats in every group except the normal control group. The body weight of rats in $CCl_4$ control group were significantly lower than other groups (p < 0.05), but the liver weight and relative liver weight were higher than normal control group (p < 0.05). The activities of ALT, AST, ALP, GTP, LDH and the level of total bilirubin in sera of rats in $CCl_4$ control group were higher and the levels of total protein, albumin and globulin were lower than the normal group (p < 0.05). The activities of ALT, AST, ALP, GTP, LDH and the level of total bilirubin in rutin 200+$CCl_4$ and rutin 400+$CCl_4$ groups were lower than $CCl_4$ control group (p < 0.05). Therefore the pre-treatment of rutin before $CCl_4$ inoculation in rats effectively inhibited the elevation of serum ALT, AST and total bilirubin which are the parameters of hepatic damage.

  • Purpose: Crigler-Najjar syndrome type II (CN-2) is characterized by moderate non-hemolytic unconjugated hyperbilirubinemia as a result of severe deficiency of bilirubin uridine diphosphate-glucuronosyltransferase (UGT1A1). The study investigated the mutation spectrum of UGT1A1 gene in Korean children with CN-2. Methods: Five Korean CN-2 patients from five unrelated families and 50 healthy controls were enrolled. All five exons and flanking introns of the UGT1A1 gene were amplified by polymerase chain reaction (PCR) and the PCR products were directly sequenced. Results: All children initially presented with neonatal jaundice and had persistent indirect hyperbilirubinemia. Homozygous p.Y486D was identified in all five patients. Three patients had an associated homozygous p.G71R and two a heterozygous p.G71R. The allele frequency of p.Y486D and p.G71R in healthy controls was 0 and 0.16, respectively. No significant difference in mean serum bilirubin levels was found between homozygous carriers of p.G71R and heterozygous carriers. Conclusion: The combination of homozygous p.Y486D and homozygous or heterozygous p.G71R is identified. The p.Y486D and p.G71R can be screened for the mutation analysis of UGT1A1 in Korean CN-2 patients.
