title: Influence of histamine or dimaprit on histamine release induced by anti-ige from human whole blood.
abstract: In human subjects histamine release from whole blood by anti-IgE and studied under several concentrations of histamine and dimaprit. The results obtained in our experiments led us to question the autoregulatory feed-back mechanism postulated by BOURNE et al. [1]. Apparently this mechanism does not apply for all patients particularly at doses which resemble physiological concentrations of histamine.
