摘要: 目的: 观察左旋组氨酸(L-His) 对戊四唑(PTZ) 和电刺激引起小鼠惊厥作用的影响。方法: 利用药物惊厥和电惊厥的实验方法, 观察L-His 对惊厥的影响及氯苯那敏对L-His 的阻断作用。结果: L-His 可拮抗PTZ、电刺激引起的惊厥, 并呈现剂量依赖性, 而氯苯那敏可部分拮抗L-His 这种作用。结论: L-His 具有抗惊厥作用, 氯苯那敏可部分拮抗L-His 这种作用, 提示L-His 能通过血脑屏障进入中枢并产生抗惊厥作用。

Abstract: AIM: To observe the anticonvulsant action of L-histidine in mice. METHODS: The anticonvulsant effect of L-histidine, and the antagonism of dlchlorpheniramine to L-histidine were observed in convulsion mice induced by pentylenetetrazole (PTZ) and electric stimulation. RESULTS: L-histidine exerted remarkable anticonvulsant action with dose-response relationship in convulsion mice induced by pentylenetetrazole and electric stimulation, and the action was partly antagonized by dl-chlorpheniramine. CONCLUSION: L-histidine has anticonvulsant effect, and the action was partly antagonized by dl-chlorpheniramine, suggesting that L-histidine can pass the BBS and enter the central nervous system.
