Methods The antimicrobial peptides of housefly larvae were induced largely by infection and injury, which were isolated and purified by trituration, centrifugalization and column chromatography. Then the antimicrobial peptides with anti-Toxoplasma activity were sieved by methyl thiazolyl tetrazolium colorimetric method and haemacytometry. The DNA contents of T.gondii tachyzoites were detected by flow cytometry.

The specific properties of materials, such as the palate adhesion, dynamic cruor, anti-bacterial and the degradability of lysozyme, were studied, which provide valuable data for further application. The main creative ideas are listed as follows:(1) The water-retention chitosan/poly vinyl alcohol blend fiber was obtained by coagulating in 10％ NaOH/ethanol solution, and the blend and crosslink due to GA can enhance the mechanical properties of fiber;(2) The controlled degradable chitosan/gelatin blend fiber was obtained by solution filature, and the mechanical properties were improved;(3) The N-acylchitosan with the different degree of substitution were successfully prepared, and the relationship between structure and properties was estabilished;(4) By a new solvent system of 6％ NaOH/4％ urea for cellulose, the blood anti-coagulant function films were prepared by blending cellulose with chitin;(5) In the same solvent system above mentioned, the anti-bacterial blend films based on cellulose and carboxymethyl-chitosan were prepared, and the relationship of DS and the anti-bacterial property was concluded;(6) The controlled degradable chitosan films was obtained by the chemical crosslink.
