Twelve non-atopic and 27 atopic preschool children were studied to determine the effect of pertussis booster vaccination on cutaneous histamine sensitivity and IgE antibody response to the naturally-occurring ragweed aeroallergen. Prick tests of histamine and ragweed extract, as well as ragweed-RAST, were performed prior to, and after, their booster(More)
Thirty-seven (74%) of 50 randomly selected non-atopic individuals gave precipitins against one or more of the seven common aeroallergen extracts surveyed by counterimmunoelectrophoresis. The precipitin lines could be absorbed out by antihuman IgG and homologous extracts, but were not affected by N-acetyl-glucosamine, protein A, heterologous extracts,(More)
Despite significant strides in serologic methodologies, the skin test, when properly done, has remained the single most sensitive and practical assay for specific dermal-bound reaginic antibody. Its value could further be enhanced if and when characterization and standardization of the allergen extracts become a reality. While the technique is simple, the(More)
