title: Release of creatine kinase by antigen, histamine, and catecholamines.
abstract: In mepyramine treated, ovalbumin sensitized anaesthetized guinea pigs protracted anaphylactic shock was produced by i.p. injection of antigen, and serum creatine kinase (CK) activities were determined 4, 6, or 17 hrs thereafter. Significant increases above nonsensitized controls were obtained. In nonanaesthetized guinea pigs shock course and serum CK increase were considerably accelerated. Histamine increased the serum CK only when given in high amounts (10 mg/kg) s.c., in the presence or absence of mepyramine. I.p. injection of histamine in mepyramine treated animals had no effect. Adrenaline (1 or 10 mg/kg) given as a s.c. depot in oil produced a significant increase of serum CK, as well as noradrenaline (0.1, 1, or 10 mg/kg). Dibenamine reduced the effect of adrenaline. In isolated perfused guinea pig hearts a significant CK liberation occurred already within the first hour after eliciting anaphylaxis. Nonanaphylactic hearts released CK too, but significant amounts were obtained only in the total 4 hrs after ovalbumin administration. Isolated anaphylactic hearts incubated in Tyrode solution liberated significantly more CK than did nonsensitized control hearts. The findings are discussed in view of a possible myocardial damage in anaphylaxis.
