title: The effect of Freund's adjuvants on blood-cerebrospinal fluid barrier permeability.
abstract: In guinea pigs with experimental allergic encephalomyelitis induced by spinal cord homogenate--complete Freund's adjuvant (CFA) emulsions an increase in the albumin permeability of the blood--cerebrospinal fluid barrier occurred from day 10 post-inoculation (p.i.) onward. In animals inoculated with CFA alone an increased albumin permeability was also demonstrated but only between days 5 and 10 after inoculation; by day 14-16 p.i. the barrier permeability had returned to control values. A similar change was seen in animals inoculated with incomplete Freund's adjuvant (IFA) only. However, both CFA and CFA-cord induced a strong humoral immune response which was not seen in animals inoculated with IFA alone. These results may have important consequences for the understanding of the development of inflammatory diseases of the central nervous system.
