Retinol and ?-Carotene inhibit PTZ-induced kindling in mice
نویسندگان
چکیده مقاله:
Vitamin A and its derivatives have recently reported to be implicated in synaptic plasticity. The possible effect of vitamin A and its precursor, ?-carotene, on seizure acquisition was tested in PTZ kindling model of epilepsy. Vitamin A and ?-carotene were tested for their ability to 1) suppress seizures (clonic and tonic) and lethality induced by PTZ in PTZ-kindled mice (anticonvulsant effect) and 2) attenuate the development of sensitization to convulsive and lethal effects of PTZ in kindled mice (anti-epileptogenic effect) when given as a pretreatment prior to each PTZ injection during kindling acquisition. Diazepam was used as positive control group. All these drugs showed anti-epileptogenic effects against PTZ-induced tonic seizures and lethality. Vitamin A and ?-carotene had no effect on clonic seizures induced by PTZ in kindled mice. It can be concluded that vitamin A and ?-carotene possess anti-epileptogenic activity. Retinoids appear to be valuable for development of a new class of anticonvulsant drugs.

Kindling, a sub threshold chemical or electrical stimulation, increases seizure duration and enhances accompanied behavior until it reaches a sort of equilibrium state. The present study aimed to explore the effect of curcumin on the development of kindling in PTZ kindled rats and its role in apoptosis and neuronal damage. In a PTZ kindled Wistar rat model, different doses of curcumin (100, 200...
