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.

S. Lewis' Narnia books, great though they may be, are not in this strict sense mythopoeic: Lewis does not want to create a self-consistent secondary world, but rather a world in which all the varieties of mythology meet and find their home.

Lewis是The Inklings的一员，纳尼亚是他所写的畅销奇幻小说，共七本）虽然是伟大的成就，但它们并不是严格意义上的神话创作，明白这一点很重要。Lewis并不想创造一个自我连贯的第二世界，而是建造了一个可以容纳所有神话因素的大本营。

Different from the Lewis acidity nature of SO4(superscript 2-)/ZrO2/MCM-41, SO4(superscript 2-)/TiO2 and S2O8(superscript 2-)/TiO2 behave mainly Brnsted acidities. The strongest Brnsted acid sites are formed on SO4(superscript 2-)/TiO2 promoted with H2SO4, while Lewis acid sites on S2O8(superscript 2-)/TiO2 are even stronger than those on SO4(superscript 2-)/ZrO2/MCM-41, and the former which are generated when persulfate solution is used as sulfating agent.

与SO4(上标 2-)/ZrO2/MCM-41主要表现为Lewis酸性不同，SO4(上标 2-)/TiO2和S2O8(上标 2-)/TiO2主要以Brnsted酸性为主，其中采用硫酸为促进剂制备的SO4(上标 2-)/TiO2具有最强的Brnsted酸性，而采用过硫酸根作为促进剂则使S2O8(上标 2-)/TiO2产生较SO4(上标 2-)/ZrO2/MCM-41更强的Lewis酸中心。
