چکیده

1. The concentrations of four serum glycoproteins, thyroxine-binding globulin, alpha 2-macroglobulin, alpha 1-antitrypsin and transferrin, as well as their reactivities with concanavalin A and lentil-lectin, were measured in patients with hepatocellular carcinoma or fulminant hepatic failure and in normal subjects. 2. Serum concentrations of thyroxine-binding globulin and alpha 1-antitrypsin were significantly greater in patients with hepatocellular carcinoma than in normal subjects, and the percentage lentil-lectin reactivity of these two proteins was markedly increased. 3. With the exception of transferrin, which did not bind to lentil-lectin, an enhancement of lentil-lectin reactivity was observed for the glycoproteins in serum from patients with fulminant hepatic failure. No difference in concanavalin A binding was found between the groups for any of the glycoproteins. 4. Altered fucosylation, as indicated by increased lentil-lectin binding, occurs in several glycoproteins arising in malignant and non-malignant conditions associated with abnormal hepatic regeneration.

Glyphosate Poisoning with Acute Fulminant Hepatic Failure

Background: Glyphosate containing herbicides are widely used the world over. They are marketed as nontoxic to humans, but numerous studies have showed that these glyphosate-based herbicides (GlySH) can cause multiorgan damage.1 Recent reports of animal studies on rats have raised a doubt of liver damage after long term exposure to GlySH. Case Presentation: a young male had chronic exposure to G...

Primary hepatocellular carcinoma presenting as fulminant hepatic failure in a young woman.

A 29 year old Caucasian female, with no history of chronic liver disease, presented with fulminant hepatic failure, the cause of which was not established until post-mortem when it was found that she had a rare form of hepatocellular carcinoma. To our knowledge, this is the only detailed report of hepatocellular carcinoma presenting in this manner.

Diminished Hepatic Binding Protein for Desialylated Glycoproteins during Chemical Hepatocarcinogenesis1

The lectin hepatic binding protein has a specific binding capacity for desialylated serum glycoproteins and is limited to hepatocyte membranes. This binding capacity was reduced by approximately 60% in the neoplastic nodules which resulted from exposure of rat livers to W-2-acetylaminofluorene. The binding capacity of the primary hepatocellular carcinomas which resulted from this regimen was re...
