Gamma-glutamyltransferase activity in ascitic fluid in diagnosis of hepatocellular carcinoma.

Hepatocellular Carcinoma in Sheep

Evaluation of serum AFP (α-fetoprotein) level in HBsAg carrier patients for diagnosis of hepatocellular carcinoma

Background: Hepatocellular carcinoma (HCC) is common all over the world as well as Iran. The incidence of HCC is higher in hepatitis B carriers and it is highly recommended to periodically screen these patients by serum alpha-fetoprotein (AFP) and liver ultrasound (US) every 6 months. We explore the diagnostic accuracy and the performance of (AFP) in cases of hepatitis B carriers as a scree...

Decrease in gamma-glutamyltransferase activity in early amniotic fluid in fetal trisomy 18 syndrome.

A study was carried out in which activity of gamma-glutamyl transpeptidase was measured in 259 samples of amniotic fluid obtained at various weeks of pregnancy. Two hundred and twenty-eight of the babies subsequently delivered had no chromosome abnormality and served as controls, while in 31 various chromosome abnormalities were detected. Mean activity of gamma-glutamyl transpeptidase in the co...

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
