[Similarities and differences in the color choice of patients under life-prolonging therapy and of healthy subjects]. / Analogie e differenze nella scelta dei colori tra soggetti in trattamento life-extending e soggetti sani.

The hypothesis of probable differences between subjects under life-extending treatment and healthy people was tested by applying the Lüscher Colour test to 2 groups of patients, one under dialysis, the other cardiopathic pacemaker wearers, and comparing them with a control group of healthy subjects. The results partly confirm the hypothesis and also show a further differentiation between the dialysis and pace-maker groups. A support programme using relaxation techniques (autogenous training and/or hypnosis) to balance and reduce problems revealed is therefore proposed.

[Autogenic training as a complementary therapy in unstable arterial hypertension in chronic uremics under periodic dialysis]. / Il training autogeno come terapia complementare nell'ipertensione arteriosa instabile dell'uremico cronico in dialisi periodica.

Consideration of the precarious mental balance of chronic uraemic patients receiving periodic haemodialysis, which often affects arterial pressure, led to a group of such patients being subjected to additional treatment in the form of Autogenous Training (A.T.). Comparison of some parameters such as arterial pressure and ECG's evaluated before and after A.T. shows, in several cases, a noticeable clinical improvement. It also has a definite tranquillising effect on the general anxiety state, which makes for better and longer-lasting adaptation to periodic dialysis. In the light of these results, Autogenous Training is proposed as a complementary treatment system for obviating certain non-physiological aspects of dialysis.

Effect of the carbon oxidation level of the energy source on heat of reaction in biosynthesis of a Pseudomonas strain.

The heats of reaction for cell biosynthesis of a strain of Pseudomonas aeruginosa grown on ammonium-nitrogen and fumarate or butyrate as carbon-energy sources have been determined by microcalorimetric experiments, CO2 and molar growth yield determinations. The different oxidation level of the fumarate-carbon (C1+) and butyrate-carbon (C1-) caused a difference on the sign of the heat of reaction for cellular biosynthesis: positive for fumarate (delta H less than 0) and negative for butyrate (delta H greater than 0). It has been possible to state the stoichiometry of the biosynthetic reaction for fumarate only and not for butyrate because of the large pigment production under the experimental conditions adopted: pure oxygen as gas phase at 30 degrees C.
