In this two-site immunochemiluminometric assay for human a1-fetoprotein, acndinium ester-labeled monoclonal antibodies are used that have an average incorporation ratio of 0.3 mol of acridinium ester per mole of antibody. The solid-phase antibody consists of sheep anti-a1-fetoprotein IgG covalently coupled to a diazonium derivative of reprecipitated aminoaryl cellulose. The assay involves a 1-h...

A 35-year-old Chinese man presented with dull pain in the right hypochondrial region for the previous 2 months. Laboratory examination revealed that his serum alpha-fetoprotein level was 1890 microg/L (reference range, 0-20 microg/L), and computed tomographic scan showed a hypodense lesion in the left liver lobe. At laparotomy, a dark reddish soft tumour (3.0 x 3.5 cm in diameter) was found in ...

Introduction: Early diagnosis of Hepatocellular Carcinoma (HCC) by imaging and biochemical tests would be valuable in controlling morbidity mortality associated with this most common primary hepatic malignancy which is the third leading cause global cancer-related deaths. Objective: To determine an association between level serum Alpha Fetoprotein (AFP) size tumor (HCC).Materials & Methods:...

Patients with hereditary tyrosinemia type 1 have an elevated risk of developing hepatocellular carcinoma, especially if initiation of treatment with 2-(2-nitro-4-trifluoro-methylbenzoyl)-1,3-cyclohexanedione is delayed. Hepatocellular carcinoma can usually be suspected when there are increased α1-fetoprotein levels and characteristic imaging features. The present case shows that a lack of a cle...

Ten (9.3%) of 107 patients with hepatocellular carcinoma had considerably increased serum unsaturated vitamin B12 binding capacity. All 10 were young (mean 12 years), had no serum alpha-fetoprotein, and no underlying cirrhosis; all had a longer survival compared with patients without increased serum unsaturated vitamin B12 binding capacity in the study. Seven of the 10 patients had fibrolamella...

The anthracycline antibiotic drug daunomycin has been coupled to fatty acids through formation of a peptide bond with the amino group of its lyxose residue. The arachidonic (C20:4) and docosahexaenoic (C22:6) acid derivatives showed potent in vitro and in vivo cytotoxic activity against rat hepatoma cells producing alpha-fetoprotein. With the exception of the acetate derivative, the complexes w...

Serum alpha-fetoprotein levels were measured serially by radioimmunoassay in 32 patients with acute viral hepatitis. With one exception, the levels were increased during the course of the illness. Raised concentrations of the protein occurred almost equally in patients with and without the hepatitis-B antigen. In the majority of patients the rise was modest but in seven levels were reached at w...

The importance of estrogens in controlling brain and behavioral sexual differentiation in female rodents is an unresolved issue in the field of behavioral neuroendocrinology. Whereas, the current dogma states that the female brain develops independently of estradiol, many studies have hinted at possible roles of estrogen in female sexual differentiation. Accordingly, it has been proposed that a...

The group-specific component (Gc) is the major vitamin D-binding protein in plasma. The gene encoding Gc is linked, on human chromosome 4, to the albumin and alpha-fetoprotein genes. These two genes previously were shown to have evolved from a smaller ancestral gene by intragenic triplication. Recombinant plasmids containing human cDNA encoding Gc have been isolated by screening an adult human ...

Two prominent alpha-fetoproteins are found in chick embryo plasma up to and slightly beyond hatching. Only antisera against chick embryo plasma resolve them. alpha3-fetoprotein is a lipoprotein, the first fetoprotein thus described. It probably functions to transport lipid from the yolk to the embryo. The other fetoprotein (alpha4) is a major glycoprotein. Both are made by the liver and yolk sa...
