[Plasma myoglobin level as a course criterium in patients with acute myocardial infarct].

Myoglobin and the enzymatic activity of creatine phosphokinase CK), MB-isoenzyme of CK (CK-MB), aspartate aminotransferase (GOT), alanine aminotransferase (GPT) and lactic acid dehydrogenase (LDH) were serially determined in 10 patients with acute myocardial infarction. Additionally the same parameters were assessed in 5 patients with angina pectoris for 24 hours after bicycle ergometry. 10 in-patients served as controls.

[Linearity and blank value in the serum creatine phophokinase MB-fraction determination by means of the inhibition test].

The inhibition test shows elevated creatine kinase MB (CK-MB) activity if the test volume is reduced. Hence, sera with considerably increased serum protein values may produce negative CK-MB results. What is involved here is an apparent blank phenomenon dependent on the serum proteins.

The action of human pancreatic and salivary isoamylases on starch and glycogen.

The hydrolytic properties of the isoenzymes of human pancreatic and salivary alpha-amylase (1,4-glucan 4-glucanohydrolase, EC 3.2.1.

The role of gamma-globulin in composition of macroamylase.

A macroamylase complex has been artificially generated by combining purified pancreatic and salivary alpha-amylase solutions with physiological amounts of human gamma-globulin. This complex was only partially dissociable at pH 3.5.

A new semiautomated fluorometric method for estimation of small amounts of L-dopa in human urine.

A semiautomated fluorometric method for the quantitative determination of urinary dopa, 3-(3,4-dihydroxyphenyl)-L-alanine, is described. It provides a simple, sensitive and reproducible analytical technique for routine use. Dopa is isolated from interfering substances, especially catecholamines, by adsorption onto aluminium oxide, elution with 0.

Isolation and characterization of isoenzymes of human salivary and pancreatic alpha-amylase.

Human salivary and pancreatic alpha-amylase (1,4-glucan 4-glucanohydrolase, EC 3.2.1.
