ObjectiveTo investigate the association between mTOR pathway and pharmacoresistance of Sprague-Dawley rat epilepsy model kindled by coriaria lactone.
MethodsA kindling model of pharmacoresistant temporal lobe epilepsy was developed by injecting Sprague-Dawley (SD) rats with coriaria lactone (CL) (1.75 mg/kg, every 84 h). Normal SD rats were injected with normal sodium (NS) served as control group. Rats with five or more consecutive stage 5 seizures were included in kindled group. Immunohistochemistry was used to detect the levels of P-S6 in both groups.
ResultsThe expressions of P-S6 in CA1 and CA3 were significantly higher compared with control group, and were mainly in astrocytes (P < 0.001). In addition, the expression of P-S6 in DG area was significantly higher than that in control group, with more granular cell and neuron (P < 0.001).
ConclusionsThe mTOR pathway may be correlated with the drug resistance of refractory lobe epilepsy kindled by coriaria lactone.
