Effectiveness of galactose-based intravenous contrast medium on color Doppler sonography of deeply located hepatocellular carcinoma.
The purpose of this study is to examine the effectiveness of intravenously injectable sonographic contrast medium for color Doppler sonographic diagnosis of deeply located hepatocellular carcinoma. Subjects were 7 hepatocellular carcinomas, an adenomatous hyperplasia and a hemangioma located more than 7 cm below the abdominal surface. Levovist, a galactose-based sonographic contrast medium was injected through median cubital vein as a phase-two clinical study, and the pre- and post-enhanced color Doppler sonographic findings of these lesions were compared. The incidence of the positive findings for hepatocellular carcinoma increased from 29% (2/7) to 86% (6/7) of hepatocellular carcinoma after contrast enhancement. Positive findings were 0% in other cases even after enhancement. Levovist brought a certain improvement in the visualization of the tumor vessel by color Doppler sonography without any noteworthy side effects. Contrast enhancement was useful for the diagnosis of liver lesions suspected to be hepatocellular carcinoma by ordinary sonography, but could not be confirmed by color Doppler sonography.

Decreased phagocytic activity of Kupffer cells in a rat nonalcoholic steatohepatitis model.
To investigate Kupffer cell dynamics and phagocytic activity, using a rat nonalcoholic steatohepatitis (NASH) model.. Male F344 rats were fed either a control diet or a choline-deficient L-amino acid-defined (CDAA) diet, followed by contrast enhanced ultrasonography (CEUS) using Levovist. The uptake of latex beads by the Kupffer cells was determined by fluorescent microscopy. The status of the Kupffer cells was compared between the two groups, using the immunohistochemical staining technique.. After 4 or more wk of the CDAA diet, CEUS examination revealed a decrease in the signal intensity, 20 min after intravenous Levovist. Fluorescent microscopic examination showed that the uptake of latex beads by the Kupffer cells was reduced at week 1 and 2 in the study group, compared with the controls, with no further reduction after 3 wk. Immunohistochemical staining revealed no significant difference in the Kupffer cell counts between the control group and the CDAA group.. CEUS examination using Levovist demonstrated reduced contrast effect and phagocytic activity in the liver parenchymal phase, although the Kupffer cell numbers were unchanged, indicating reduced phagocytic function of the Kupffer cells in the rat NASH model. We believe that CEUS examination using Levovist is a useful screening modality, which can detect NASH in fatty liver patients.
