title: Investigations on allergogenic properties of Tołpa Peat Preparation.
abstract: The ability of Tołpa Peat Preparation (TPP) to induce or enhance an allergic sensitization was tested on mice and guinea pigs. The levels of IgE antibody in the mouse sera and IgG1 as well as IgE antibody levels in guinea pig sera were evaluated by PCA (Passive Cutaneous Anaphylaxis) tests. TPP adsorbed on aluminium hydroxide gel (alum) and introduced into BALB/c mice by several subcutaneous injections was unable to stimulate the noticeable anti-TPP IgE antibody response. TPP introduced together with ovalbumin (OA) into the mice in the course of immunization with OA did not enhance anti-OA IgE antibody response. TPP adsorbed on alum and injected subcutaneously into guinea pigs was unable to induce noticeable IgG1a, IgG1b and IgE antibody response, and mast cells obtained from lung and mesentery of these animals did not release histamine when challenged with TPP in vitro at 37 degrees C. In conclusion, our results show that under the experimental conditions used in the present experiments TPP was unable to induce or enhance an allergic sensitization of mice and guinea pigs.
