目的 探索临床针刺加当归芍药散治疗阿尔采默氏症的可能机理方法通过腹腔注射药物东莨菪碱或亚硝酸钠，或者用奎宁酸损毁脑海马CA 1 区诱发大鼠发生记忆力障碍，造成不同类型的大鼠&痴呆&模型，对照性观察针刺、针刺加DGSYS、DGSYS及NM对记忆障碍功能的影响和与记忆相关实验指标参的变化。

Biological characteristics of Curvularia lunataBoedijn had been preliminarily studied. Optimal mediums for pathogen growth were PSA,PDA and OMA.For mycelia growth,sporulation and conidial germination of pathogen,optimal temperature was 25～30℃,and pH 5～9.Among the tested carbon and nitrogen resources,sucrose,glucose,carbamide,sodium nitrate,etc were beneficial for mycelia growth and sporulation.The conidia germination is strict in RH requirement:Conidia can germinate at RH 81%～98%,or have 100% germin...

香蕉大灰斑病菌适合生长的培养基有PSA、PDA和OMA；菌落生长、产孢和孢子萌发最适宜的温度为25～30℃，pH 5～9；在碳源和氮源中，蔗糖、葡萄糖、尿素、磷酸氢二氨和硝酸钠有利于病菌生长和产孢；分生孢子萌发对湿度有严格的要求，RH≥80%以上分生孢子萌发，随湿度增加萌发率增高；光照对菌丝体无显著影响，光暗交替有利于孢子的形成；孢子致死温度为55℃(10min)。
