[Isoenzymes of creatine kinase: distribution in the skeletal muscle and in sera of patients with muscular diseases or damages (author's transl)].

In skeletal muscle isoenzymes of CK were determined by immunprecipitation and chromatography. The activity of CK-MB was between 17 and 47 U/g muscle, corresponding to a quota between 2,1 and 4,2% of the total activity. In sera of patients with muscular dystrophy, polymyositis, hypothyroidism, after arterial embolism, epilepsy, hyperventilation, operations and polytrauma with and without injury to the thorax isoenzymes were measure by immune precipitation- and immune inhibition-test. The percentage of CK-MB in all sera was less than 6% of the total CK-activity (range: 0 to 6%). Only patients in the first day after neurosurgical operations showed a quota till to 6.5% CK-MB. In serum of patients after polytrauma without injury to the thorax the percentage of CK-MB ranged from 0-5.7% while after polytrauma with injury to the thorax and a reasonable suspicion of a damage to the myocardium this quota was between 5.1 and 23.6% of the total activity. CK-BB activity was not detectable in any cases. Therefore a disease or damage of the skeletal muscle is more probable, if the percentage of CK-MB in less than 6%, because in sera of patients with myocardial infarction in the first 48 h after beginning of the symptoms this quota of CK-MB in the most cases in more than 6%.

[Special aspects of fracture healing in cranio-cerebral injuries].

This study demonstrates the changes of concentration and elimination of calcium, phosphate and zinc, as well as alteration of serum alkaline phosphatase and acid phosphatase especially in patients with severe brain injuries in connection with bone fractures. Because the study has not been completed, the presently acquired results should only demonstrate possible development of the examined parameters. To find out the pathogenesis of overgrowing callus in brain-injured patients, further examinations are being carried out to find the histochemical activities of alkaline and acid phosphatase, lactate dehydrogenase, adenosine triphosphatase and acetylcholine esterase.

[Comparative methods for the determination of the activity of serumcholinesterases (acylcholin-acyl-hydrolase E.C. 3.1.1.8) and their diagnostical value (author's transl)].

The activities of serum cholinesterases were determined in parallel with acetyl-, butyryl- and propionyl-thiocholiniodide in healthy persons and patients with acute and chronic hepatitis, cirrhosis of the liver, fatty liver, cholestasis, intoxication and malignant tumors. The following normal values were obtained: See Article. The correlations between the various methods, especially between butyryl- and propionylthiocholiniodide are statistically significant. Compared to healthy persons, the activity of serum-cholinesterases, determined with the three substrates, decreased significantly in patients with acute and chronic hepatitis, cirrhosis of the liver, intoxication and malignant tumors. A change of specificity of serum-cholinesterases towards acetyl-, butyryl- and propionylthiocholiniodide in normal persons and patients with endogenous or exogenous coma of the liver was not observed. In all cases a parallel decrease of activity in sera was determined.
