Popis: Effects of ketamine on glutamate-induced swelling of astrocytes in primary cell culture were studied. Following the exposure to 1 mM glutamate (Glu) for 4 h the intracellular water space (as measured by 3-O-methyl-[ 14 C]glucose uptake) of astrocytes was increased by two-fold concomitant with cell swelling and disappearance of cellular processed observed by phase-contrast microscopy. Ketamine, when co-incubated with Glu, reduced the astrocytic swelling in a dose-dependent manner. These data suggested that ketamine, in addition to its function as a non-comparative N-methyl- d -aspartate receptor antagonist, is also involved in protecting astrocytes from Glu-induced swelling.
