[COMPLEX IMMUNOGLOBULIN PREPARATION FOR THERAPY OF PERTUSSIS IN YOUNG CHILDREN].

AIM: Study the possibility of inclusion of complex immunoglobulin preparation (CIP) pos- sessing specific activity against pertussis exotoxins into complex therapy of pertussis infection in young children. MATERIALS AND METHODS: -2 groups of children with.pertussis younger than 3 years were examined. The main group (50 individuals) received CIPper os - 1 dose 1 - 2 times per day for 5 days, comparison group (34 children) received only basic therapy. Evaluation of clinical effectiveness of CIP was carried out, the content of anti-pertussis class G antibodies and total IgE in patients were studied. RESULTS: A good clinical effectiveness of the preparation was shown, as well as immune modulating activity against humoral immune response to pertussis infection. CONCLUSION: The detected positive effect of CIP on pertussis -course in children has indicated a principally novel use of this per oral drug form.

Isolation of the C3 complement component and its C3d subunit from IY-1 fraction of Cohn's fractionation of human plasma.

C3 complement component and its C3d subunit were isolated from the IY-1 Cohn's fraction, which is the waste of industrially produced albumin and immunoglobulins. The first step was the fractionation of precipitate IY-1 by polyethylene glycol (PEG) 4000 to a final concentration of 16% PEG. The precipitate formed was separated by centrifugation. The supernatant contained the C3d subunit of C3, and the redissolved 16% PEG precipitate contained the C3 component. Then the supernatant and the dissolved precipitate were subjected to anion-exchange chromatography on DEAE-Toyopearl 650 M. In the last step fractions containing C3 and C3d concentrated by ultrafiltration were chromatographed on Sephacryl S-200.
