ABSTRACT
Lagerstroemia speciosa Pers,also known as banaba,belongs to Lythraceae and contains ursolic acid,corosolic ac?id,asiatic acid and 30 other kinds of effective components.It has multiple pharmacological activities,including hypoglycemic,hypo?lipidemic,anti-oxidant and anti-viral activities,and is mainly used for the treatment of obesity and diabetes in folk medcine.This re?view summarizes the recent advances in chemical composition and pharmacological effects of L.speciosa Pers,so as to provide the theo?retical basis and reference for its further research and application.
ABSTRACT
OBJECTIVE@#To observe and analyze the characteristic of mutation at STR locus.@*METHODS@#27 mutant genes observed in 1211 paternity testing cases were checked by PAGE-silver stained and PowerPlex 16 System Kit and validated by sequencing.@*RESULTS@#Mutant genes locate on 15 loci. The pattern of mutation was accord with stepwise mutation model. The mutation ratio of male-to-female was 8:1 and correlated to the age of father.@*CONCLUSION@#Mutation rate is correlated to the geometric mean of the number of homogeneous repeats of locus. The higher the mean, the higher the mutation rate. These loci are not so appropriate for use in paternity testing.
