Effect of L-propionyl carnitine on some properties of erythrocytes and leukocytes of alcohol abusers.

The effect of L-propionyl carnitine, the carnitine derivative utilized as a more effective drug for membrane protection, on Na-K ATPase activity of erythrocyte ghosts of alcohol-dependent patients and blood donors has been investigated. The effect of L-propionyl carnitine on leukocyte chemotaxis and cytochrome c reduction, a measure of superoxide ion production was also studied. It has been in fact observed that alcohol is immunotoxic on both the non-specific and the specific immune response.

[Pollutants in biological fluids].

The AA. report the gaschromatographic determination of some metal hazards encountered in the environment, as berylliu, chromium, manganese, cobalt, nickel, tin, lead, mercury and others. They develop the rapid method by Hansen et al.

[Analytical method to identify and quantitate residues of aromatic polychlorinated hydrocarbons (author's transl)].

A analytical method to identify and quantitate residues of polychlorinated biphenyls, polychlorinated terphenyls, polychorinated naphtalenes and some chlorinated pesticides is described. These contaminants can be recovered from foods or other materials: a silicic acid coloumn chromatografic method previously developed is used to separate PCB's, PCT's, PCN's from organochlorinated pesticide residues. The PCB's, PCT's, PCN's residues identification and their subsequent quantitation can be achieved by conversion into well defined single perchloro-derivatives, viz decachlorobiphenyl, o.
