Abstract

BACKGROUND: Assessment of hepatic functional reserve is important in hepatic resection. The aim of this study was to evaluate the role of hepatic asialoglycoprotein receptor (ASGP-R) analysis in the preoperative estimation of remnant liver function in liver surgery. METHODS: One hundred and one patients undergoing hepatic resection for liver tumours were studied. Seventeen patients had preoperative percutaneous transhepatic portal vein embolization (PTPE). Function of the hepatic remnant was estimated before surgery using radioactivity in fusion images of both liver single-photon emission computed tomography and computed tomography scans using (99m)Tc-labelled diethylene triamine penta-acetate-galactosyl-human serum albumin. RESULTS: All three patients with an ASGP-R concentration below 400 nmol/l and preoperative total amount of receptor in the future remnant liver (R0-remnant) of less than 53.0 nmol per liver died. Two patients with chronic hepatitis and R0-remnant values between 53.0 and 65.0 nmol per liver and a receptor concentration lower than 600 nmol/l developed liver dysfunction. The incidence of liver failure decreased inversely with increasing R0-remnant value. CONCLUSION: A combination of receptor concentration and the amount of hepatic receptor in the future liver remnant as detected on fusion images is useful in evaluating the risk of postoperative liver failure.

Abstract

We want to establish a system of volume reduction by the incineration of the combustible radioactive solid wastes from radioisotope usage at the utilization facility. We have been performing experiments using an experimental incineration system to examine the distribution of radionuclides during incineration and to collect basic data. To reproduce the realistic conditions of incineration of low-level radioactive wastes in an experimental system, we adopted new incineration methods in this study. Low level radioactive samples (LLRS) were set up in a mesh container of stainless steel and incinerated at high temperature (over 800•Ž) generated by two sets of high calorie gas burners. Low energy ƒÀ-emitters 35S, 45Ca, 33P, and a high energy ƒÀ-emitter 32P were used for the experiment. Their translocation percentages in exhaust air and dust were estimated using the Imaging Plate. Distribution of radionuclides during the incineration was similar to that estimated by conventional methods by our study or to that reported in incineration of liquid scintillation cocktail waste. We concluded that the use of the Imaging Plates is a simple and reliable method for estimation of the distribution of low energy ƒÀ-emitters in incineration gas and ash.

Abstract

Insulin-like growth factor binding protein-3 (IGFBP-3) is a mediator of growth suppression signals and a putative tumor suppressor gene. The growth suppression mechanisms of IGFBP-3 have not been well clarified. We examined the expression of IGFBP-3 transcripts in human hepatocellular carcinoma (HCC) and the relationship between IGFBP-3 expression and the transforming growth factor-beta (TGF-beta) and/or retinoblastoma (Rb) signaling pathways. In situ hybridization revealed IGFBP-3 transcripts in cancer cells in 6 of 57 (10%) HCCs, including moderately and poorly differentiated HCCs with intrahepatic metastasis. In contrast, all lung metastatic nodules of 4 HCCs showed IGFBP-3 transcripts in cancer cells. The cDNA microarray showed that genes for the TGF-beta pathway and Rb were up-regulated in IGFBP-3-expressing HCCs. In 6 HCCs presenting IGFBP-3, immunohistochemical analyses showed abnormalities in the TGF-beta and/or Rb pathways; the loss of phosphorylated-Smad2 was observed in 2, and overexpression of phosphorylated-Rb was observed in the remaining 4 HCCs. The present study suggests that IGFBP-3 mediates growth suppression signals via the TGF-beta and/or Rb pathways in HCC.

Abstract

Background/aims: The genes responsible for hepatocellular carcinoma have not been identified. To identify the relevant genes of hepatocellular carcinoma, detailed and comprehensive information of genomic aberrations must be obtained. To reveal the chromosomal aberrations in hepatocellular carcinoma, we carried out a restriction landmark genome scanning analysis of various types of hepatocellular carcinoma., Methodology: Samples of various types of hepatocellular carcinoma, including two with multinodular-hepatocellular carcinomas, one hepatocellular carcinoma showing nodules in a nodule pattern, one hepatocellular carcinoma metastasized to different tissues, three small (< 2.0 cm) hepatocellular carcinomas and four large (> 5.0 cm) hepatocellular carcinomas were examined by the restriction landmark genome scanning method with corresponding non-hepatocellular carcinoma tissues. Restriction enzyme Not I was used as a landmark enzyme, Eco RV was used as a fragmentation enzyme, and Hin fI was used as a digestion enzyme in the gel for two-dimensional electrophoresis., Results: We observed spot aberrations with different origins. Frequently observed spot aberrations originated from the change in the methylation status of repetitive sequences. No clear correlation between the pathological grade and the number or type of spot aberrations was observed., Conclusions: We demonstrated that major aberrations of restriction landmark genome scanning spots originated from the change of methylation status in hepatocellular carcinoma.
