Under the auditory evoked brain stem potential (ABP) examination, the latent period of V wave and the intermittent periods of III-V peak and I-V peak were significantly shortened in Parkinson's disease patients of the treatment group (N=29) after acupuncture treatment. The difference of cumulative scores in Webster's scale was also decreased in correlation analysis. The increase of dopamine in the brain and the excitability of the dopamine neurons may contribute to the therapeutic effects, in TCM terms, of subduing the pathogenic wind and tranquilizing the mind.

甘草酸软膏治疗豚鼠慢性湿疹模型的实验研究
目的 观察甘草酸软膏抗炎、止痒和对豚鼠慢性湿疹的治疗作用.方法 雄性昆明种小鼠、雌雄昆明种小鼠、白色豚鼠各60只,分别随机分为模型对照组(10只)、基质对照组(10只)、醋酸地塞米松乳膏组(10只)、甘草酸软膏高(10只)、中(10只)、低(10只)剂量组,各组分别建立二甲苯致小鼠耳廓肿胀模型,右旋糖酐40致小鼠搔抓模型,以及2,4-硝基氯苯反复刺激的慢性湿疹豚鼠模型,分别观察甘草酸软膏对小鼠耳廓肿胀和搔抓反应以及慢性湿疹豚鼠耳廓肿胀的影响.结果 甘草酸软膏高、中剂量可以抑制二甲苯致小鼠耳廓肿胀(P＜ 0.05或0.01)；甘草酸软膏高剂量可以延长有旋糖酐致小鼠搔抓的潜伏期,甘草酸软膏高、中、低剂量可减少搔抓次数(P＜ 0.05或0.01),减轻慢性湿疹豚鼠模型耳廓的肿胀(P＜0.05或0.01),并对耳廓皮肤的病理改变有一定的改善作用.结论 甘草酸软膏对慢性湿疹豚鼠模型有一定的治疗作用.
