AIM To make clear whether CD147 (EMMPRIN) expression in pathological tumor samples with a fine-needle aspiration biopsy is useful for pathological diagnosis of early hepatocellular carcinoma (HCC). METHODS Twenty-two patients (15 men and 7 women; median age 68 years, range 56-81 years) underwent a liver tissue biopsy in order to make a diagnosis of HCC.(More)
A conjugate of doxorubicin and glutathione via glutaraldehyde (GSH-DXR) inhibited glutathione S-transferase (GST) activity of rat hepatoma AH66 cells, and treatment of the cells with GSH-DXR induced caspase-3 activation and DNA fragmentation. After treatment of AH66 cells with 0.1 microM GSH-DXR, GST-P (placental type of rat GST isozymes) mRNA and its(More)
It was confirmed that CD147 (Emmprin) was expressed on the cell surface of carcinoma cells. For the purpose of studying the efficacy of a CD147-targeting agent on CD147-expressing carcinoma cells, we investigated the effect of a conjugate of glutathione-doxorubicin (GSH-DXR) encapsulated in an anti-CD147 antibody-labeled liposome (aCD147ab-liposome) in(More)
BACKGROUND Alcohol abuse can induce testicular atrophy, but it only occurs in some alcoholics. Alcohol dehydrogenase (ADH) is located principally on the Leydig cells. METHODS To investigate whether genetic polymorphism of alcohol dehydrogenase (ADH) 2 and aldehyde dehydrogenase (ALDH) 2 was related to alcoholic testicular atrophy, we determined(More)
Alcohol abuse can induce brain atrophy, but it only occurs in some alcoholics. To investigate whether genetic polymorphism of alcohol-metabolizing enzymes [including alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH)] was related to alcoholic brain atrophy, we determined restriction fragment-length polymorphisms of the ADH2 and ALDH2 genes in 77(More)
A 29-year-old woman was referred to our hospital for the intensive examination of leg edema and hypoproteinemia. CT scan of showed multiple thin-walled cysts in both lungs, suggesting lymphangioleiomyomatosis. CT scan of the abdomen, lymphoscintigraphy showed enlarged abdominal lymph nodes. Protein loss from the gastrointestinal tract was documented by(More)
AIM To determine factors predictive for esophageal varices in severe alcoholic disease (SAD). METHODS Abdominal ultrasonography (US) was performed on 444 patients suffering from alcoholism. Forty-four patients found to have splenomegaly and/ or withering of the right liver lobe were defined as those with SAD. SAD patients were examined by upper(More)
BACKGROUND A carbohydrate-deficient transferrin (CDT) is the most useful marker of alcohol abuse; however, the mechanism of production and the pathophysiologic roles of CDT remain obscure. The effects of alcohol and its metabolites on growth and proliferation, transferrin synthesis, and phosphomannomutase enzyme activity in a human hepatoblastoma, HepG2,(More)
A case of female alcoholic who developed liver cirrhosis with small amounts of alcohol by the common use of contraceptive agent was reported. A case was a 33-year-old female who had complained of systemic edema and jaundice. She had been drinking alcohol, while she had been taking the contraceptive agent from 20-year-old. On admission, she had a large(More)
