[The flight behavior of hand grenade fragments and their shock-producing effect on the human].

Systemic affects by multiple hits of corpuscular material are not seen until a level of ergy about 600-800 J is reached. A major determinant is the sum of energy. A potentiating effect could not be observed.

Systematic investigation of degradation effects on spin-lattice relaxation times in mouse-liver by low resolution NMR.

In spite of numerous work on in vitro proton relaxation time investigations of biological tissue, many questions still remain open. In this study we focused on spin-lattice (T1) relaxation time measurements of mouse liver tissue in order to estimate the time-after-excision effects. The post mortem behaviour of excised tissue was measured up to four hours in intervals of about nine minutes.

Systematic investigation of degradation effects on spin-spin relaxation times in mouse-liver by low resolution NMR.

Despite numerous work on spin-lattice (T1) relaxation in vitro, not much attention has been paid on spin-spin (T2) relaxation until now. In this study we are presenting spin-spin relaxation time measurements of mouse liver tissue in order to estimate the time-after-excision effects. The post mortem behaviour of excised tissue was investigated up to four hours in intervals of about nine minutes.

Influence of some uremic toxins on oxygen consumption of rats in vivo and in vitro.

According to our present knowledge hypometabolism and hypothermia in uremia are most probably due to direct actions of toxic substances at the cellular level. A cardiovascular etiology seems less possible. A similar reduction of oxygen consumption as observed in uremia can be produced by 5 mg/kg body wt.

Metabolism of free fatty acids (FA) and triacylglycerol (TG) in acute and subacute fluoride intoxication of the rat.

In rats acute intoxication with 100 mg sodium fluoride/kg body wt. orally has the following metabolic consequences. Oxygen consumption is reduced by about 30-50%.

Reduced hepatic fatty-acid synthesis and lowered plasma triacylglycerol (TG) in potassium deficient rats.

Potassium deficiency was induced in rats by feeding a potassium- free synthetic diet containing 5% Resonium A. Feeding this diet for 1 week resulted in a decrease of plasma potassium by about 50% vs. pair fed controls.

Increased serum triacylglycerol and cholesterol binding reserve in acute uremic rats.

In acute uremic rats (24 h after bilateral nephrectomy, serum urea 280-300 mg/dl) the interface tension of the serum is significantly reduced. Serum levels of triacylglycerol are significantly elevated in uremia, whereas cholesterol levels do not show a significant alteration. The in vitro serum binding reserve for both, triacylglycerol and cholesterol is considerably enhanced.

[On the effect of cadmium on tissue respiration and gluconeogenesis in rat kidney cortex (author's transl)].

Oxygen consumption (QO2), respiratory quotient (RQ) and gluconeogenesis of rat kidney cortex slices were determined (Warburg technique). QO2 was not influenced by 0.01 mM CdCl2 in the incubation medium (no exogenous substrate added), 0.
