Electrocardiographic findings in cystometric procedures.

Twenty-eight elderly patients, mostly with minor electrocardiographic abnormalities, underwent cystometry and simultaneous recording of the electrocardiogram in order to assess the influence of intravesical pressure elevation with regard to electrocardiographic changes. During cystometry intra-atrial, atrioventricular and ventricular conducting time remained unaffected, while the cardiac rate showed a moderate but significant increase without any serious impairment of cardiac function. It is concluded that slow filling without overdistension of the bladder can be considered safe even in elderly patients with cardiovascular problems.

[HDL cholesterol: clinical and pathobiochemical aspects (author's transl)].

The determination of high density lipoprotein (HDL)-cholesterol in patients with mild hypercholesterolemia (240-300 mg/dl) allows one to distinguish between hyperbetalipoproteinemia (= high atherogenic risk) and hyperalphalipoproteinemia (= low atherogenic risk). In addition, analysis of HDL-cholesterol is of value in the prediction and early recognition of coronary heart disease, particularly in combination with known risk factors (hypertriglyceridemia, adipositas, smoking). This prognostic value of HDL-cholesterol is a result of its negative correlation to coronary heart disease which has been recognized in epidemiologic and clinical studies.

[Correlations between age, risk factors for arteriosclerosis and endocrine functions (author's transl)].

In 377 males and 528 female factory workers basal serum levels of glucose, neutralfat, cholesterol, Na, K, Ca and LH, FSH, TSH, Prolactin, GH, Insulin, total corticoids and testosteron were determined. Mean values and standard deviations as well as correlations between mean basal hormone levels and other serum parameters, blood pressure and relative body weight (Broca Index) and partial correlations excluding age and relative body weight were calculated. Basal serum levels of LH, FSH, GH and prolactin show age and sex dependent secretion patterns.

[Free amino-acids of the plasma in atherosclerotic patients (author's transl)].

18 free amino-acids have been valuated in a group of patients recovering from myocardial infarction dating more than one year back and in another group of healthy active athlets. In the group of the ill persons the mean values of the following amino-acids were significantly higher: Arginine, asparagine-acid, phenylalanine, valine, lysine, serine, threonine, leucine, proline and tyrosine. While in the group of the healthy persons the following amino - acids proved to have significantly higher values: alpha -- aminobutter-acid, glycine and cystine.

[Investigations on LH and FSH serum levels before and after application of synthetic LH-releasing-hormone in healthy men of different age].

50 male healthy volunteers of different age had measurements of plasma luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Basal levels of LH and FSH as well as maximal release of both hormones after i.v.
