ABSTRACT
A novel H17N10 subtype of the influenza A viruses was found in bats in 2012. Protein sequence and structural analyses revealed that the HA17 and NA10 proteins of this strain are different from corresponding ones in known influenza A subtype viruses. Both HA17 and NA10 proteins cannot bind to sialic acid,which indicates that they may have novel functions. This article briefly describes the state of current research into the H17N10 subtype of bat influenza A virus.

In this report, the immunopharmacological effects of Polyactin A ( PAA ) were presented. When the SRBC immunized mice were administered daily 2. 5~40mg/kg ( ip ) of PAA for 3 or 5 days, the serum level of hemolysin, the antibody production in spleen and the number of nucleated cells of spleen were enhanced significantly; and the efficacy-dose dependency was evident in these experiments。 In spite of these effects, PAA didn't affect the kinetics of circulating antibody level.In other experiments, it was found that the efficiency was more potent when PAA was given before or simultaneously with SRBC immunization than given after.
