Plasma carcinoembryonic antigen (CEA) and serum enzyme levels of phosphohexose isomerase (PHI), gamma-glutamyl transpeptidase (psi-GTP), and lactate dehydrogenase (LDH) were measured in 147 patients with malignancy. Levels were higher in patients (particularly with G.I., breast and lung cancers) than in normals or in patients with cancer in clinical(More)
We evaluated the clinical usefulness of lipid-bound sialic acid (LSA) as a "tumor marker" and assessed individual and carcinoembryonic antigen (CEA) in cancer patients. Serum LSA and CEA concentrations were measured by the resorcinol method after total lipid extraction and isolation of the sialolipid fraction, and by Abbott enzyme immunoassay procedures,(More)
A comparison was made between pre- and post-run serum levels of total creatine kinase (CK), CK-MB isoenzyme, lactate dehydrogenase (LD) and myoglobin (MG) levels in 84 runners in each of three groups; male 5-10 mile run; female 5-10 mile run; and male 15-55 mile run. Levels of CK-MB and MG were quantified using radioimmunoassay, while total CK and LD were(More)
Carcinoembryonic antigen and activities of glucosephosphate isomerase (EC 5.3.1.9), gamma-glutamyltransferase (EC 2.3.2.2), and lactate dehydrogenase (EC 1.1.1.27) were measured in aqueous extracts of fetal, normal adult, and malignant human colon tissues. Fetal colon, as well as primary and metastatic colon tumor tissue, showed higher activities of these(More)
