title: Liver, plasma and erythrocyte phospholipid content after chronic diazepam treatment in the rat.
abstract: Male Wistar rats were maintained on a nutritionally adequate diet and diazepam was administered in a dose of 10 mg/kg/day. Control animals were pair-fed an adequate diet. Feeding was continued for 180 days, and the effects on the liver, plasma and erythrocyte phospholipid content were studied. It was found that the contents of sphingophospholipids and phosphatidylinositol + phosphatidylserine were significantly reduced in the erythrocytes of diazepam-treated rats. There was a significantly increased content of phosphatidylcholine in the liver an erythrocytes after 180 days of diazepam treatment. Such treatment did not cause statistically significant changes in the plasma of diazepam-treated rats. These investigations are in agreement with the hypothesis that extended or chronic use of drugs such as diazepam may alter membrane-dependent processes.
