OBJECTIVETo study optimum inclusion conditions for volatile oil from three medicinal slices in Xiongdan Xiaoyan capsules.
METHODSaturated water solution method (agitation method), ultrasonic method and rubbing method were studied and compared. The preparation conditions of ultrasonic method were investigated by the orthogonal test.
RESULTThe optimum inclusion conditions of ultrasonic method were established.
CONCLUSIONThe ultrasonic method can be used for production of inclusion complex in the factory with high inclusion rate and was effectiveness.

Objective To study the features of Yersinia pestis(Y.pestis)in areas along Qinghai-Tibet Railroad in Qinghai Province.Methods To identify the biologic types and the molecular biological feathers of Y.pestis isolated from areas along Qinghai-Tibet Railroad in Qinghai from 2001-2006.Results All the tested Y.pestis was biologically of classical type and ecologically of Qinghai-Tibet plateau type.The Y.pestis had high virulence.The Y.pestis of 65×106 plasmids was distributed in the Tanggula area,the Y.pestis of 52×106plasmids,in Tianjun and Delingha areas.The Y.pestis srains carried 52 × 106 plasmids.except the two containing 65 X 106 plasmids in Wulan County.The genetic type of Y.pestis in Tanggula was type 5 and that in Zongwulong of Delingha,Saishike,Keke,Tongpu of Wulan was type 8 except 2 strains of Y.pestis isolated from woodchuck and the patients in Dananwan of Tongpu,Wulan County were type 15.Conclusion The Y.pestis in the area along Qinghai-Tibet Railroad in Qinghai belongs to Qinghai-Tibet plateau type with high virulence.
