[Plasma levels of free fatty acids, triglycerides and cholesterol in acute subrenal kidney failure]. / Plasmakonzentration der Freien Fettsäure, des Triglyzerids und Cholesterins bei akuter subrenaler Niereninsuffizienz.

The plasma triglyceride, cholesterol, and free fatty acid levels were determined in patients with acute subrenal kidney failure. Like in chronic uraemia, the levels were higher than normal. The findings were confirmed in animal experiments which showed that the plasma lipid fractions will rise after a single day of bilateral renal occlusion and the rise is proportional to the duration of the occlusion. The lipid levels remain higher than in the controls for some time after relief of the occlusion.

[Morphological lesions of the kidney in acute bilateral subrenal occlusion]. / Morphologische Nierenveränderungen bei akuter, bilateraler, subrenaler Okklusion.

The effect on the kidney of a bilateral transitory occlusion of the ureter was studied. The extent of the oedematous swelling of the kidney was determined and the dilation of the pelvis and the condition of the vessels were studied. Changes were observed in the renal tissue. The vessels appeared to be in a functional spasm, Bowman's capsules and the tubules were dilated and signs of vacuolar degeneration were manifest in the parenchyma. Mannitol administered after relieving the occlusion enhanced renal regeneration. The oedema disappeared in a shorter time than otherwise and the degenerative symptoms ceased.

[Substitution of venous valves in animal experiments]. / Der Ersass von Venenklappen im Tierversuch.

60 to 70 per cent of properly transplanted autologous venous grafts with intact valves maintain the functional capability of their valves. The procedure might be of clinical importance in the treatment of the postthrombotic syndrome.
