  • Title: Lead acetate action on anaphylactic response of guinea pig smooth muscle.
    Author: Gijón E, Cartas L, García X.
    Journal: Proc West Pharmacol Soc; 2001; 44():145-6. PubMed ID: 11793963.
    Abstract:
    Experiments were performed to evaluate lead acetate effects on the anaphylactic contraction in guinea pigs smooth muscles. Aortic rings from guinea pigs exposed to lead acetate developed an anaphylactic contraction significantly lower than the contraction induced by the antigen in controls. In the smooth muscle of the intestine, lead acetate did not modify the anaphylactic response. Lead induced immunosuppression of the anaphylactic response of aortic rings, whereas sodium acetate had no effect on the anaphylactic reaction of the guinea pig smooth muscle. The amplitude of the norepinephrine contraction was not modified by lead nor by sodium acetate.
