目的观察托吡酯(top iram ate,TPM)对红藻氨酸(kain ic ac id,KA)致癫痫持续状态(status ep ilepticus,SE)大鼠海马神经元凋亡的影响。方法取大鼠120只,随机分为TPM组、KA组及生理盐水(NS)对照组,每组再分为四个小组,分别用于SE后3、12、24和48 h四个时点。每小组10只大鼠。TPM组用TPM预处理。采用KA诱导大鼠SE。进行行为学评估、HE染色及TUNEL染色,并用免疫组化方法检测海马caspase-3的表达变化。结果TPM组大鼠的癫痫发作迟于KA组。HE及TUNEL染色显示,TPM组大鼠海马的病理损伤轻于KA组。免疫组化结果显示,TPM组caspase-3的表达明显低于KA组。结论TPM对KA诱导的SE发作具有抑制作用,并能显著降低海马caspase-3的表达,从而减轻癫痫所致的海马神经元损伤。
Objective: To understand the behavioral characteristic of children with bronchial asthma. Methods: 60 children with bronchial asthma and 60 normal children subjects were rated on the Rutter Behavioral Scale. Results were analyzed and compared between the groups. Results: Children with bronchial asthma obtained higher total score, higher N and A subscale scores in Rutter Behavior Scale than the control group. Conclusion: In general, children with bronchial asthma showed more behavioral problems than normal children.
