Voltammetric and spectrometric determination of antioxidant capacity of selecte...

Considering the presence of phenolics in grapes and wines, as well as their importance for health promoting properties, the DPPH (1,1-diphenyl-2-picrylhidrazine) assay and a novel electroanalytical approach (differential pulse voltammetry – DPV) for analysis have been performed in order to compare the antioxidant activity of different grape beverages. A total of fifty-two wine samples from different regions aro...

Antinociceptive properties in mice of a lectin isolated from the marine alga Am...

The antinociceptive effects of a lectin (LEC) isolated from the marine alga Amansia multifida were determined in Swiss mice. The LEC (1, 5, and 10 mg/kg) inhibited acetic acid-induced abdominal writhings in a dose-dependent manner after intraperitoneal or oral administration. A partial but significant inhibition of writhings was observed after the combination of LEC (10 mg/kg) with avidin (1 mg/kg), a potent in...

Gamma-glutamyltransferase and alcoholic hepatic disease.

Accepting the principle that Gama-gt values are elevated in alcoholic patients, the authors attempted to find out if that enzyme might be helpful in distinguishing alcoholics with or without hepatic morphologic lesion. 110 alcoholic patients with and 57 without histologically proved hepatic lesion were studied. The authors conclude that a single determination of Gama-gt lacks specificity to detect, among the al...
