Regulation of Antibody Formation by Serum Antibody
Rabbits were immunized to two antigens and 18-55 days later exchange transfusion was performed using blood of rabbits immunized to one antigen only. By this means, serum antibody levels to one antigen were reduced 50-84% while maintaining serum antibody levels to the second antigen. After exchange, serum antibody levels of the removed antibody rose rapidly for 24-48 hr and then more slowly, rea...
متن کاملAntibody Formation* I. the Suppression of Antibody Formation by Passively Administered Antibody Bx
In 1909, Theobald Smith (1) showed that injection of partially neutralized diphtheria toxin-antitoxin mixtures induced antitoxin formation in experimental animals, but that immunity did not result from mixtures containing a sufficient excess of antitoxin. These observations were subsequently confirmed (2-6) and have been extended to the study of additional antigens, such as tetanus toxoid (7-10...
متن کاملSerum Level of Helicobacter pylori Antibody in Stroke Patients
Background and Objective: Stroke is the third most common cause of death in developed countries and the most common disabling neurological disease. There are several risk factors for stroke. Regarding this, the present study was conducted to investigate the effect of Helicobacter pylori antibody on the incidence of stroke. Materials and Methods: This case-control study was conducted on 50 pati...
متن کاملThe Antibody-formation by Polysaccharids
1. By complement fixation tests, it has been clearly demonstrated that the sera of rabbits immunized with inulin, soluble starch and dextrine contain specific antibodies. 2. All these immune sera gave a negative precipitation reaction. 3. The kind of dextrine which has a construction very near to starch has an antigenic property, but those in a state of further decomposition do not give rise to...
متن کاملAntibody Formation
Diphtheria toxoid-antitoxin precipitates formed in antitoxin excess can prepare guinea pigs, rats, and rabbits for a secondary type of antitoxin response. Priming may occur without the development of detectable serum antibody. In rats, toxoid-antitoxin precipitates are more efficient than "free" toxoid in priming, whereas in guinea pigs, the magnitude of the anamnestic response varies with the ...
