STUDY OF INFLUENCE OF PREVIOUS ORAL APPLICATION OF DIPHTHERIA ANTIGENIC PREPARATIONS ON RABBIT ALLERGIC REACTION FORMING AFTER SKIN TEST

It’s studied an influence of previous oral application of diphtheria antigenic preparations on allergic inflammation forming after skin test. It’s used destroyed by ultrasonic microbe cells C.diphtheriae var. gravis tox+ massachusets, free from destroyed cells by the use of centrifugation supernatant and refined concentrated diphteria toxoid. Experimental rabbits are fed to 3,5 ml of one of antigenic preparations (the total protein dose is 33,6 mg), control ones are fed to saline. In a week all animals were injected intracutaneously 0,2 ml each of corresponding antigenic preparation. The findings testify to decreasing manifestation tendency of rabbit skin reactions on antigenic preparations.
