ABSTRACT
Objective To compare the differences of salivary alpha(α) amylase (sAA) activity and its activity ratio from the sali‐va before and after citric acid stimulation and approach the correlations among sAA activity determined by the methods of iodine‐starch ,Bernfeld and EPS‐G7 velocity respectively .Methods Ten saliva samples were collected from five healthy volunteers before and after citric acid stimulation .Their activities were determined three times by the three methods ,and the variation coefficient (CV) of sAA activity and activity ratio were calculated .Moreover ,correlation among sAA activities determined by the three meth‐ods were analyzed .Results The significant differences (P 0 .05) in sAA activities ratio and its CV ;Significant correlation was found between sAA activity determined by random two of three methods(P < 0 .05) ,and their correlation coefficients were above 0 .96 .Conclusion The sAA activity data determined by three methods could be transformed each other by regression equation ,and determined precision by the method of EPS‐G7 velocity is highest ,and data processing method of sAA activity ratio could decrease differences among CV from three methods .
ABSTRACT
Objective:To approach the status quo and characteristics of traditional Chinese medicine(TCM) in intefering the related cardiovascular risk factors in obese type 2 diabetes mellitus(T2DM).Methods:The recent 10 years documents about nitric oxide(NO),endothelin(ET),C reactive protein(CRP),and etc.,eight cytokines which are involved in T2DM and its cardiovascular complications were retrieved and statistically analyzed and all related TCM were pykno-analyzed.Results:① CRP was the focal point at home and abroad,adiponectin(APN) was the hot spot in recent years.② The documents of ET at home was greatly more than that abroad,it may hint some diversity between different races.③ The related TCM were mainly characterized by cleaning heat,enriching yin and qi,activating blood circulation and removing stasis.④ ET and NO were the hot spots in the TCM fi eld.Conclusion:TCM had certain effect on the cardiovascular risk factors above in obese T2DM.
