A new antisickling agent: in vitro studies of its effect on S/S erythrocytes and on hemoglobin S.

2-(benzoylamino) pyridinium benzoate (BAPB) has exhibited an antisickling effect with homozygous S/S erythrocytes in vitro. This study suggests that BAPB prevents sickling by inhibiting the gelation of hemoglobin S.

The effect of purine bases and nucleotides on ethanol-induced fatty liver syndrome.

Rats fed a special liquid fat diet had a higher level of liver triglycerides than rats fed a normal solid chow diet. The ingestion of ethanol induces a concomitant increase in hepatic triglycerides and a depression of ATP levels. Pure adenine base administered orally produces a significant reduction of hepatic triglycerdies and partially restores ATP levels in the chronic ethanol treated rat.

The effects of aflatoxin B1 on rat fetal lung lipids.

The administration of aflatoxin B1 to rats on days 17 and 19 of pregnancy caused increased synthesis of the total lipids and the fatty acids, and decreased synthesis of the phosphatidyl choline in 21-day-old fetal lung. Aflatoxin B1 caused toxicity in the fetal lung as evidenced by the excessive accumulation of the lamellar bodies and the osmiophilic spheroids in the type II cells and the alveolar lumen, respectively. The rearrangement of the lamellar form to the continuous sheet-like tubular myelin form was reduced in the alveolar lumen of the treated lung.
