Abstract

Objective To investigate the preventive effects of curcumin for status epilepticus (SE) induced by lithium chloride-pilocarpine. Methods Totally 45 Sprague-Dawley (SD) rats were randomly divided into three groups: preventive group ( n = 15 ), non-preventive group ( n = 15 ), and control group ( n = 15 ). The latency peroid and incidence of SE were recorded. The surviving neurons were stained by using nissl staining, and the programme death cells were detected by using terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) in hippocampal CA3. Results The SE incidence of preventive group was 66. 7%, which was significantly lower than that of non-preventive group ( P 〈 0. 05 ). The latency period of preventive group [ (41.0 ± 18. 1 ) min ] was longer than that of nonpreventive group [ (21.5 ±8. 2) min]. The numbers of surviving neurons and programme death cells showed no significant difference between the preventive group and non-preventive group ( P 〉 0. 05). Conclusion Pretreatment of cureumin can prevent the SE induced by lithium chloride-pilocarpine and the pretreatment can not protect the neuron. Key words: Status epilepticus/chemically induced/drug therapy; Curcumin/pharmacology/therapeutic use; Lithium chloride/ adverse effects; Pilocarpine/adverse effects
