Objective: According to current neurophysiological evidence, the
role of 5-hydroxytryptamine (5-HT) receptors in epileptic seizure formation is
still not fully elucidated. The aim of this study was to investigate the
effects of 5-HT1A receptor on epileptic seizure with
pentylenetetrazole induced epilepsy in rats.
Method: In this study, 28 male Wistar Albino rats weighing
240-260 g were used. Pentylenetetrazole (PTZ, 35 mg/kg, i.p.) was injected to
the rats to induce epilepsy and seizure stages were determined according to the
Racine scale. Electrodes were placed in the skulls of the animals under stereotaxis
for ECoG recording. All the experimental animals were sacrificed by
decapitation after ECoG and video recordings. GABA level was measured using the
Elisa kit from brain tissues, and c-Fos expression was shown
immunohistochemically.
Results: According to the results, it was shown that 8-OH-DPAT
increased the time of initial myoclonic jerk (FMJ (p<0.05). However, the
number of epileptic spikes was reduced by 8-OH-DPAT (p<0.05). GABA levels
decreased in PTZ group (p<0.05). 8-OH-DPAT and WAY-100135 decreased c-Fos
expression in all hippocampal areas (p<0.05).
Conclusions:
In conclusion, 5-HT1A
receptor agonist 8-OH-DPAT, showed an anti-epileptic effect. The anti-epileptic
effects of 5-HT1A receptor were found to be inconsistent with
changes in GABA level. c-Fos expression is a marker of neuronal activation and
may be related to the anti-convulsive effect of 5-HT1A receptor.
