Abstract

Swelling of primary astrocyte cultures by exposing them to hypotonic media caused release of label after the cells had been allowed to accumulate 3H-L-glutamate, 3H-D-aspartate, or 3H-taurine. Comparable release of endogenous L-glutamate or taurine, as measured by high-pressure liquid chromatography (HPLC), was also found. Release of label was not affected by treating the cells with cytochalasin B, indicating that microfilament polymerization was not significantly involved. Hypotonic-induced release did not appear to principally involve reversal of the Na(+)-dependent uptake system since increasing external K+ to depolarize the cells by replacement of external Na+, thus maintaining isotonic conditions, increased release to a lesser extent. Threo beta-hydroxyaspartate, a potent 3H-L-glutamate uptake blocker, added externally stimulated efflux of 3H-L-glutamate independently of the swelling-induced efflux. Upon restoration of swollen cells to isotonic medium they showed an unimpaired ability to take up 3H-L-glutamate. The swelling-induced release of label was inhibited by a number of anion transport inhibitors, one of which has been shown to significantly improve outcome in an experimental brain trauma/hypoxia model in which astrocyte swelling is an early event.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
