Abstract/OtherAbstract:
The erythrocyte constitutes a good model system for the study of membrane-associated toxicity events caused by the trichothecene mycotoxin, T-2. This study confirms that T-2 has a direct lytic effect on erythrocytes. Lysis of guinea pig red cells requires approx. 10(10) molecules/cell and reaches plateau values after 4-6 h. An activation energy, Ea approximately equal to 4.5 kcal was derived from the Arrhenius equation. By use of osmotic blockers of differing Stokes' radii, the functional size of the membrane lesion caused by T-2 toxin was shown to be smaller than 5.5 A. It is concluded that T-2 toxin may exert its toxic effects via the cell membrane.
