Ethanol was administered to Wistar male rats for 4 or 10 months and to female rats for 21 2 months (including gestation), using a 20% ethanol-water solution as the only fluid. Gangliosides (expressed as NeuAc) from forebrain, cerebellum, brain stem, liver and kidney of the alcoholic rats and their newborns were determined by densitometry. Forebrain and liver from males showed a statistically significant increase in their ganglioside-NeuAc content after 4 months of alcohol ingestion. In addition, when the treatment lasted up to 10 months the increase was larger. In contrast, a significant decrease of cerebellar and kidney ganglioside-NeuAc content was found after 10 months. The ganglioside pattern of the different sources displayed a variable profile. Moreover, while alcohol fed mothers showed a significant increase in the ganglioside-NeuAc content of cerebellum and liver, and a decrease in the brain stem, newborns of mothers given alcohol in their drinking water exhibited an increase of ganglioside-NeuAc content in cerebellum, liver and kidney and a decrease in forebrain.

Ganglioside a/b ratio in different rat brain regions following chronic diazepam treatment.

Gangliosides are sialic acid-containing glycosphingolipids that play a variety of important functions in neurons. The main purpose of this study was to determine the a/b ratio of gangliosides in different rat brain regions (cerebral cortex, hypothalamus, caudate nucleus, hippocampus, thalamus and cerebellum) after prolonged diazepam treatment. Male Wistar rats were maintained on a nutritionally adequate diet and diazepam was administered in a dose of 10 mg/kg day for 180 days.

The main purpose of this study was to determine the content and composition of cerebellar gangliosides after prolonged diazepam treatment and their possible recovery after diazepam withdrawal. Male Wistar rats were administered diazepam in a dose of 10 mg/kg/day in drinking water for 3, 5 or 6 months. A additional group of rats had a one-month recovery period after five months of diazepam treatment.

To elucidate whether or not gangliosides on the bovine erythrocytes serve as a receptor for Theileria sergenti merozoites, the reactivities of the T. sergenti piroplasms with gangliosides were studied by the liposome agglutination test. The parasites reacted weakly with I-active ganglioside containing N-acetylneuraminic acid (NeuAc) and strongly with I-active ganglioside containing N-glycolylneuraminic acid (NeuGc).

The major ganglioside NeuAc alpha 2-->3Gal beta 1-->4Glc beta 1-->1Cer (GM3) present in cultured rat granulosa cells was examined for potential function in the expression of luteinizing hormone (LH) receptor on the cell surface in response to follicle-stimulating hormone (FSH). Synthesis of GM3 was stimulated concentration-dependently by FSH, and the stimulation was enhanced synergistically by insulin, as revealed by metabolic labeling of glycosphingolipids with [3H]galactose. When granulosa cells were cultured in the media containing GM3 (0.
