METHODS: Three different MBP peptides(MBP6886, 8799, and the nonencephalitogenic peptide 110128) were synthesized and administrated nasally to Lewis rat on day11, 10, 9, 8 and 7 prior to immunization with the guinea pig MBP + CFA, which was used to induce EAE. The protective effect on Lewis rat from EAE by the MBP peptides was evaluated.

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.
