Anticonvulsant effects of 1,25-dihydroxyvitamin D in chemically induced seizures in mice

Kalueff, Allan V., Minasyan, Anna, Tuohimaa, Pentti·2005·Brain Research Bulletin

Abstract

Here, we study the role of a neurosteroid hormone Vitamin D in epilepsy. To examine this problem, we used 1,25-dihydroxyvitamin D, an active form of Vitamin D, injected subcutaneously to NMRI mice (33 microg/20 microl) 40 min prior to seizures induced by systemic injection of pentylenenetrazole (PTZ, 70 mg/kg). Overall, compared to the vehicle-treated control animals (n=11 in each group), the Vitamin D-treated mice demonstrated reduced severity of PTZ-induced seizures (longer latency, shorter duration and lower mortality). In a separate experiment, we assessed the time-course of antiepileptic effects of 1,25-dihydroxyvitamin D. For this, we injected this compound (33 microg/20 microl) to NMRIx129S1 mice (n=11) 40 min, 3, 6, 12 and 24 h prior to seizures, showing that antiepileptic effects were short-term, almost disappearing 3h after administration. Our findings show that Vitamin D plays a direct anticonvulsant role in the brain and suggest that the Vitamin D endocrine system may represent a new target for the development of anticonvulsant drugs.

  • 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.
