Studies on Complement Fixation Test in a Mouse Immuni­zed with Japanese B Encephalitis Virus.

1) I designed a new micro-method for complement fixation test by means of a capillary pipette. 2) By this method, the complement-fixing antibodies in an individual mouse could be tested without taking its life. 3} The complement fixation titers in mice immunized with Japanese B encephalitis had a considerable individuality. 4) An adjuvant containing anhydrous lanoline and paraffin-oil, when mixed with Japanese B encephalitis vaccine, was effective to potent complement-fixing antibody productions in mice to this antigen.
