[Relation between HDL cholesterol and ECG findings]. / Untersuchungen über Beziehungen zwischen HDL-Cholesterol und Ekg-Befunden.

In 255 males the HDL-cholesterol values were compared with the results of the load-ECG-investigations. A statistically significant accumulation of findings in the load-ECG with references to a chronic ischaemic heart disease and a HDL-cholesterol level lower than 0,90 mmol/l is the result. It is recommended in correspondence with literature to use the estimation of LDH-cholesterol for the diagnostics and the control of the therapy of the chronic ischaemic heart disease.

[Dependence of hippuric acid excretion in urine on the toluol concentration and the respiratory volume per minute]. / Untersuchungen zur Abhängigkeit der Hippursäureausscheidung in Harn von der Toluolkonzentration und dem Atemminutenvolumen.

In inhalative toluol loads lasting one hour a dependence of the secretion of hippuric acid on the concentration of toluol in the inspiration air influenced by the respiratory minute volume was shown. It is concluded that the estimation of the hippuric acid from a one- to two-hours' collective urine of the working shift may give actual references to the toluol load. The increase of hippuric acid in the urine of 1.5 g/l after toluol exposition refers to the transgression of the MAK-values according to TGL 22310.
