Résumé
OBJECTIVE:To gain clear idea of influence of multiorigins of Cordyc ep s on quality and nature of this drug.METHODS:The mannitol contents in the Cordy ceps samples collected from different growing areas were determined and compared ,and their MDR(Mutual Different Rate)was analyzed.RESULTS:The MDRs among specim ens from Sichuan,Tibet and Yunnan were 0.012～0.32 and the MDRs among the Cordyc eps samples from different micro-ecological environment were 0.037～1.36.CONCLU SION:On the mannitol content in Cordyceps,the effect of the species diversity a nd the micro-ecological environment might exceed that of district and climate d ifference.
Résumé
The paper discusses several relationships that hospital directors must correctly handle. These include: relationship between the orientation of running the hospital and the implementation of the Party's general and specific policies, relationship with the higher authorities, relationship between the two chiefs, relationship with the deputies, relationship with the department heads, and relationship with the staff members.
Résumé
Object To investigate and compare the scavenging effect of Cordyceps growing in different environment on hydroxyl radical. Methods 10-Phennanthroline-Fe 2+ oxidative assay was used to observe the effect of scavenging hydroxyl radical from H_2O_2/Fe 2+ system by the aquenous extracts of Cordyceps. Results Cordyceps from Naqu of Xizang,northwest Yunnan,and northwest Sichuan all showed us the significant effect on scavenging of hydroxyl radical produced from Fenton Reaction. The biggest values of MDR among Cordyceps specimens from various microecological environment surpassed that among specimens of Naqu of Xizang,northwest Yunnan,and northwest of Sichuan. Conclusion The aquenous extracts of Cordyceps could scavenge the hydroxyl radical from Fenton Reaction. The microecological environment for Cordyceps growing has an significant effect on its scavenging action.
