A hepatic angiomyolipoma is a rare benign tumor mainly composed of blood vessels, smooth muscle cells and fat cells in varying proportion. Hepatic angiomyolipoma is often misdiagnosed as a hepatocellular carcinoma in preoperative imaging work-up. To date, there has been little published data describing PET findings of hepatic angiomyolipoma. We report one case of hepatic angiomyolipoma that showed a high acetate and relatively low FDG uptake on PET images.

To investigate the postmortem changes in hepatic cell membrane, the rats were sacrificed with cervical dislocation and kept in an incubator at $25^{\circ}C$, 70% of humidity for 12 hours. The biochemical experiments in postmortem were done at 2, 4, 8 and 12 hours. The degree of rigor mortis and algor mortis were increased with the time during 12 hours. The contents of hepatic malondialdehyde were rapidly increased ai 2 hours, and gradually decreased afterward. In histological findings, after 8 hours, the clotted blood was seen in central vein and sinusoids, and especially portal veins were dilated a1though the structure of hepatic lobules was preserved well. Furthermore, both in the histochemical and enzymatic examinations, membrane bounding alkaline phosphatase activities were gradually decreased with the time. In conclusion, the activity of membrane bounding alkaline phosphatase was linearly decreased with time in the early postmortem period and so it might be referred to the possibility fur the estimation of death time in the early postmortem period.

Objective : This study was designed to investigate the effects of herbal medicine on jaundice caused by hepatic resection. Methods : This study was carried out on one patient with jaundice ensued by hepatic resection. The patient was admitted on October 25th, and treated until November 13th, 2004, using acupuncture and herbal medicine(Hepacure-I and Ex.Sosiho-tang.) Result : After 18 days, clinical symptoms had improved. Results of total bilirubin, ALP, GGT tests and urinalysis also showed improvement. Conclusions : These result support a role for this combination of acupunture and herbal medicine in treatment of chronic liver disease.

A 5-year-old intact female Persian cat was referred with anorexia and vomiting. Physical examination revealed icterus in the pinna, oral mucosa, and sclera. Ultrasonography revealed several findings including uniformly hyperechoic hepatic parenchyma compared to adjacent falciform fat, increased attenuation of the ultrasound beam, and poor visualization of intrahepatic vessel borders. Computed tomography revealed hypoattenuation of the hepatic parenchyma with a radiodensity value of -60 Hounsfield units. The adjacent intrahepatic vessels appeared hyperattenuated relative to the hepatic parenchyma as if the vessels were contrast-enhanced. Based on ultrasonography and computed tomography results, the cat was tentatively diagnosed as feline hepatic lipidosis.

The present study was undertaken in order to elucidate the effects of pretreatment with nicotinamide on changes in the hepatic metabolizing enzyme system inducted by streptozotocin (STZ). In rats, STZ(50mg/kg) administered by tail vein caused a significant rise in hepatic aniline hydroxylase and a decrease in aminopyrine N-demethylase when compared to control (p<0.05). Pretreatment with nicotinamice inhibited these effects (p<0.05). Similarly, STZ induced changes in hepatic microsomal cytochrome P-450 activity were inhibited by pretreatment with nicotinamide (p<0.05). However, changes in UDP-glucuronyl transferase and sulfortransferase activity were not significantly different(p>0.05). Pretreatment with nicotinamide also prevented STZ induced increases in glutathion S-tranferase activity when compared to the control(p<0.05). There results suggest that nicotinamide pretreatment suppresses STZ-induced changes in the hepatic metabolizing enzyme system.

Congenital hepatic fibrosis is an inherited, congenital disorder of the liver characterized by portal hypertension and hepatic fibrosis. We experienced a case of congenital hepatic fibrosis with esophageal varix in a 9-year-old male. He complained hematemesis, hematochezia, dizziness. In laboratory examination, AST/ALT was slightly increased. Esophageal varix was noted by an endoscopic examination. Hepatosplenomegaly and hypoechoic lesion of periportal area were seen by abdominal CT scanning. Histologic finding of liver biopsy showed fibrous tracts containing dilated bile ductules connecting adjacent portal spaces that were widened by mature fibrosis. Endocopic sclerotherpy and ligation was done. We summarized a case with review of literatures

This paper dealt with the light microscopical and electron microscopical findings on the morphological changes of the liver of Korean native goat injected with toxin (culture filtrate) of Clostridium perfringens which was isolated from Korean native cattle died of acute Clostridium perfringens enterotoxemia. The results observed are summarized as follows. In the microscopical findings, hyperemia and minute hemorrhage of the liver parenchyma, dilatation of hepatic central vein and centrilobular necrosis of liver, cloudy swelling and hydropic degeneration of hepatic cells, and appearance of light eosinophilic granular bodies in the vacuoles were recognized. In the electron microscopical findings, appearance of pinocytotic vesicle (coated vesicle), fusion of these vesicles, formation of vacuole and accumulation of minute granular proteinous materials in the vacuole were observed in the hepatic cells. Decreased number of glycogen granules, swelling and destruction of mitochondria, proliferation of smooth-surfaced endoplasmic reticulum, enlargement of rough-surfaced endoplasmic reticulum, dispersal of thready agranular membranous structure and appearance of secondary lysosome were recognized in the hepatic cell cytoplasm.

Inborn error of metabolism usually presents with a constellation of clinical pictures involving multiorgan systems. Because of its rarity and clinical diversity, it is difficult to make diagnosis accurately and efficiently. Many inborn error of metabolism shows predominantly hepatic symptoms and signs. The onset of symptoms is also varying depending the disease. The onset might be even prenatal, either neonatal or infantile, and late childhood. The major manifestation patterns are jaundice or cholestasis, hepatomegaly with or without splenomegaly, hypoglycemia and acute or chronic hepatocellular dysfunction. Based on pronounced hepatic symptoms and onset of symptoms, differential diagnosis can be more easily made with subsequent further laboratory investigation. In this review paper, major inborn error of metabolism with hepatic symptoms are described from the perspective of mode of clinical presentations.

The biologically active component of licoris(Glycyrrhizae Radix L.) is considered to be glycyrrhetinic acid, an aglycone of glycyrrhizin, on the basis of chemical and pharmacological studies. The present study was undertaken to investigate the effect of glycyrrhetinic acid on the hepatic morphine-6-dehydrogenase activity, which catalize morphine to morphinone. Morphine-6-dehydrogenase was further purified by centrifugation, $(NH_4)_2SO_4$ fractionation, sephadex G-100, hydroxyapatite column. Hepatic morphine-6-dehydrogenase activity was significantly decreased by the treatment of glycyrrhetinic acid. When effect of glycyrrhetinic acid on the hepatic morphine-6-dehydrogenase was investigated in vitro, it was powerfully inhibited the enzyme activity with dose-dependent manner. From the above results, glycyrrhetinic acid inhibits hepatic morphine-6-dehydrogenase activity and decreases the morphine induced harmful side effects.

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.
