摘要:
Purpose: To examine the effects of current shunt on rats with temporal lobe epilepsy and neocortex epilepsy. Experimental Design: A kainic acid (KA)-induced model of temporal lobe seizure and a penicillin-induced model of neocortical partial seizure were used in this study. Rats of each model were randomly allocated into two groups: control and model groups. The model group was further divided into the KA or penicillin group, sham conduction group and conduction group. The current shunt was realized through the implantation of a customized conduction electrode. After surgery, electroencephalogram (EEG) was recorded for two hours for each rat under anesthesia. Subsequently, the rats were video monitored for 72 h to detect the occurrence of behavioral seizures upon awakening. The average number and duration of seizures on EEG and the number of behavioral seizures were measured. Results: In KA model, the number of total EEG seizures in conduction group (9.57 +/- 2.46) was significantly less than that in sham conduction group (15.13 +/- 3.45) (p<0.01). The duration of EEG seizures in conduction group (26.13 +/- 7.81 s) was significantly shorter than that in sham conduction group (34.17 +/- 7.25 s) (p=0.001). A significant reduction of behavioral seizures was observed in the conduction group compared with KA (p=0.000) and sham conduction groups (p=0.000). In penicillin model, there was a 61% reduction in total EEG seizures in conduction group compared with sham conduction group (p<0.01), and the duration of EEG seizures in conduction group (6.29 +/- 2.64 s) was significantly shorter than that in the sham conduction group (12.07 +/- 3.81 s) (p=0.002). A significant reduction of behavioral seizures was observed in conduction group compared with penicillin (p<0.01) and sham conduction groups (p<0.01). Conclusion: Current shunt effectively reduces the onset and severity of seizures. Current shunt therapy could be an effective alternative minimally invasive approach for temporal lobe epilepsy and neocortex epilepsy.
