Abstract

Organic lithium salts containing anionic components (succinate, fumarate, pyruvate and antioxidant ascorbate) were tested for protection of blood plasma proteins and lipids against ethanol-induced oxidation in vitro. We used normothymic lithium carbonate and well-known antioxidant dipeptide carnosine (b-alanyl-L-histidine) as the reference drugs. The oxidized proteins and lipids were determined by the level of carbonylated proteins (CP) and TBA-reactive products (TBA-RP), respectively. In alcoholic patients the level of oxidized proteins and lipids was higher than in healthy persons. Incubation of blood with ethanol resulted in an increase in oxidized proteins and lipids in blood plasma of healthy persons but had no influence on the level of CP and TBA-RP in blood plasma of alcoholic patients. Lithium carbonate, lithium ascorbate, and lithium succinate exhibited protective action against ethanol-induced oxidation of biomolecules of blood plasma of healthy people. These effects were comparable with carnosine action. The studied compounds had no effect on the level of CP and TBA-RP of blood plasma of alcoholic patients.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
