Reactivity of the isolable disilene R*PhSi=SiPhR* (R* = SitBu3).

The disilene R*PhSi=SiPhR* (R* = supersilyl = SitBu3), which can be quantitatively prepared by dehalogenation of the disilane R*PhClSi-SiBrPhR* with NaR* (yellow, water- and air-sensitive crystals; decomp at ca. 70 degrees C; Si=Si distance 2.182 A), is comparatively reactive.

[Psychophysical stress reactions during a psychoanalytic interview].

In 37 young volunteers analytically oriented interviews were taken and their effects being compared to those of conventional stressors using mental arithmetic. Because of their similarity to day-to-day stressors we expected higher cardiovascular reactions (blood pressure, heart rate and catecholamines) under interview situations than in mental arithmetic. Conforming this hypothesis, we found higher reactions in blood pressure regulation, while heart rates were not higher under interview situations compared to laboratory stressors.

Effect of renal function on cytokine secretion of monocytes and lymphocytes.

The effect of renal function on cytokine secretion capacity of mononuclear cells was analysed in patients who had not been subjected to any form of renal replacement therapy. The aim of the study was especially to determine whether there is a defect of monocyte function. The patients were divided into three groups of 12 on the basis of renal function: group I, serum creatinine 1.
