[X-rays taken by nurses].

Medical technology makes use of ionising radiation in many ways to diagnose and treat disease. One of these is X-rays. In rural areas there are hospitals where the services of a radiographer are not available and nurses take over this task. No formal training is available for these nurses in order to equip them with the necessary knowledge and skills to take X-rays. This article looks into the nature of this phenomenon.

Rolipram in major depressive disorder: results of a double-blind comparative study with imipramine.

Rolipram improves signal transmission in central noradrenergic neurones at a pre- and postsynaptic level, and is thus a novel approach in antidepressant therapy. In order to prove efficacy, tolerance, and safety, several controlled studies are underway. Results of a randomized double-blind comparative trial versus imipramine involving 64 in-patients with Major Depressive Disorder (DSM III) in six independent centers will be presented and discussed. The chosen biometric model provided evidence that towards the end of the study imipramine was superior to Rolipram. The particular clinical relevance of this difference is discussed. As regards tolerance, nausea emerged as the typical side-effect of Rolipram, whereas imipramine precipitated mainly anticholinergic side-effects.

[Preliminary physiological and psychological results under various electroclimatic conditions (author's transl)].

Before the start of a research project which was to stretch over a period of several years, characteristics of the control space were to be defined. Therefore the influence of spherics and 50 Hz-alternating fields in the unscreened control space were studied.--Pupils (Foster children) were the test subjects. Each test subject was subjected to the conditions of the control space as well as the testing space.--Two classes of parameters were studied. Blood sugar, blood pressure and pulse rate were recorded as physiological dimensions. Short-term memory, powers of concentration as well as the subjective well-being were the psychological parameters.--As to the parameters examined, no significant difference between testing and control space conditions was recorded. In order to examine whether the climatic factors of the control space have an antagonistic effect on the variables in question, their influence was studied separately in two further investigations. In order to clarify this problem, spherics-impulses in the 10 Khz range were given in screened space ("Vorversuch 2"/preliminary experiment 2), then--in, "Vorversuch 3"/preliminary experiment 3 - a 50 Hz-alternating field was applied. For each of the climatic factors under examination the influence on each single parameter was negative. The assumption of an antagonistic effect which would hinder the definition of standard spatial conditions was thereby shown to be incorrect.
