[Polymorphism of 17 Y-STR loci in She ethnic population in Fujian and genetic relationship with 11 populations].

To investigate the genetic polymorphisms of 17 Y-chromosomal short tandem repeats(Y-STR) loci in She ethnic population from Fujian province, and to evaluate their forensic application values and genetic relationship with other 11 populations, 152 unrelated male individuals of She ethnic population in Fujian were used to determine the distribution of allele frequencies and haplotypes by using Y-filerTM System. Cluster analysis and phylogenic trees were applied to show the genetic distance among the populations. As a result, 50 haplotypes were found in DYS385a/b loci, and 3～11 alleles were found in the rest 15 Y-STR loci.

Production and immunoanalytical application of 32 monoclonal antibodies against metacestode somatic antigens of Echinococcus multilocularis.

Alveolar echinococcosis is a rare but potentially fatal disease. Immunodiagnosis based on antibodies or antigens plays an important role in its diagnosis. In this study, metacestode somatic antigens of Echinococcus multilocularis were used to immunize BALB/c mice, and hybridomas were formed by cell fusion.
