The production of creatine kinase isozyme BB in sera of a patient with prostatic carcinoma and in tumor homogenates.
1. A CK(BB) fraction was observed in sera of a patient with prostatic carcinoma. The fraction accounted for 59% of the total enzyme activity. A metastatic tumor of a prostatic carcinoma was observed to contain solely the CK(BB) isozyme. An embryonal testicular carcinoma was observed to have a higher percentage of the CK(BB) fraction when compared to the adjacent tumor free testicular tissue in a third patient. These studies suggested that in certain carcinomas there are tissue isozyme modifications at the molecular level. The isozymic modification was suggested as a reversion towards an embroyonic pattern as the adult molecular form tended to disappear while the fetal form increased. This too suggests that the isozymes of CK may be a useful model in elucidating the mechanism through which this transition occurs. 2. The high percentage of CK(BB) in the sera of the patient with metastasis was discussed. The origin could not be determined, but either a primary tumor or a metastatic tumor by their enzyme modifications could account for this increased fraction in sera.
Colorimetric determination of creatine phosphokinase isoenzymes: detection in tissues and serum, and usefulness as an aid to diagnosis of myocardial infarction.
1. A colorimetric procedure for creatine phosphokinase (E.C.2.7.3.2.) isoenzymes suitable for routine laboratory use its described. The method utilizes a commercial product for visualization of CK isoenzymes in both serum and tissues. 2. The technic has been applied as an aid to the diagnosis of acute myocardial infarction. An intermediate migrating isoenzyme band (CK-MB) was detected in sera of 19 patients with clinical evidence of myocardial infarction and two patients with myocardial ischemia. The CK(MB) was absent in three patients presenting with symptoms suspect of, but not clinically confirmed as having myocardial infarction.
