Administration of 1,25-dihydroxyvitamin D3 results in the elevation of hippocampal seizure threshold levels in rats

Abstract

Electrical stimulation of the dorsal hippocampal formation of the rat was employed to determine the effect of 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3), the hormonal form of vitamin D, on induced seizure thresholds. Stereotaxic injection of 100 micrograms or 50 micrograms 1,25-dihydroxyvitamin D3 in 2 microliter propylene glycol into the hippocampus resulted in a significant elevation in seizure threshold in all animals treated. 1,25-dihydroxyvitamin D3-induced increases were noted within 5-10 min and lasted at least 120-180 min after injection when the experiments were terminated. Intravenous injection of 1,25-(OH)2D3 also resulted in a significant elevation of seizure threshold; however, the increase was transient, lasting only 30 min. This effect was specific since 200 micrograms vitamin D3 or 200 micrograms 25-hydroxyvitamin D3 (25-(OH)D3), injected into the hippocampus, had no effect on seizure threshold levels. This investigation represents the first direct demonstration of a role for 1,25-(OH)2D3 in the regulation of seizure activity and suggests, along with the previously demonstrated presence of immunoreactive vitamin D-dependent calcium binding protein and receptors for 1,25-dihydroxyvitamin D3 in the brain, that the vitamin D endocrine system may play a significant role in the physiological mechanisms underlying convulsive disorders.

  • Vitamin D and its analogues increase seizure threshold in animal studies.

    “Vitamin D and its analogues have been shown to increase seizure threshold, potentiate anticonvulsant activity of antiepileptic drugs, and to decrease the severity of seizures in animal studies [194,195,196].”

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.
