title: Dose-dependent impact of pretreatment (imprinting) with histamine and serotonin on the phagocytic activity of Tetrahymena.
abstract: Serotonin and histamine stimulate the phagocytic activity of Tetrahymena at primary interaction. The effect of histamine is dose-dependent. While serotonin elicits an imprinting-like phenomenon at a high concentration, histamine induces no imprinting, probably for 1 volutionary reasons.
