Allergic Encephalomyelitis

[摘要] 1. 1. By extraction of whole moist bovine spinal cord with petroleum ether, a fraction can be obtained which is highly encephalitogenic when combined with Freund adjuvants and injected intracutaneously into guinea pigs.2. 2. Fractionation with acetone, chloroform and methanol yields a preparation which causes a high rate of allergic encephalomyelitis when injected in 5-γ amounts. This material contained 6.3% nitrogen.3. 3. Further fractionation yields a fraction (almost completely protein) which is found to be highly encephalitogenic in 2-γ amounts.
