Intragastric antigen sensitization and treatment:

Sensitization was performed by 20 [micro]g OVA gavage with 10 [micro]g cholera toxin in 0.2 ml saline for 5 times once a week using a stainless steel blunt feeding needle. Mice in the non-sensitized control group received saline. Experimental diet included 0.1% or 0.3% red ginseng or fermented red ginseng. Mice were fed the experimental diet for 8 weeks starting at 1 week before the initial sensitization. …

EAE induction and clinical evaluation:

EAE was induced by s.c. immunization with 100 mg MOG3555 peptide in 100 ml CFA containing 0.4 mg Mycobacterium tuberculosis H37RA (Difco); 200 ng pertussis toxin (List Biological Laboratories) was administered i.v. on days 0 and 2.
