[Thromboembolic risk factors in kidney transplantation: hemorheologic examination in secondary polycythemia].

Cardiovascular risk factors will increase the lethality of kidney patients being under dialysis treatment and after transplantation. This risk is additionally increased after transplantation by secondary polycythemia. The paper investigates the rheological properties of the blood of 20 patients affected by secondary polycythemia after kidney transplantation, 10 patients without polycythemia after kidney transplantation and 19 test persons.

[Oxygen exchange processes between the dialyzing fluid and the blood during hemodialysis and resultant practical consequences].

The polarographic measuring technique was used to examine the processes of oxygen exchange between dialysing fluid and blood during haemodialysis in 21 patients of the chronic haemodialysis programme. During haemodialysis there is a tendency for the arterial oxygen partial pressure to fall; on the statistical average this is slight, in individual cases it is a marked tendency. With the apparatus KNA 302 (without degassing facilities) the blood is slightly oxygenated.

[Behavior of important serum lipid fractions in chronic hemodialysis patients and following kidney transplantation].

In patients in the chronic programme of haemodialysis and 51 patients with transplanted kidney selected lipid-chemical parameters were investigated and compared. 1. Disturbances of the lipid metabolism more frequently occurred in patients with transplanted kidney than in chronically haemodialyzed patients.

[Effect of ultraviolet irradiation on renal osteopathy in patients in the chronic hemodialysis program].

Under influence of the ultraviolet radiation the formerly lowered 25-hydroxycholecalciferol (25-OH-CC) level increases in persons with healthy kidneys. Such investigations were not yet carried out in patients undergoing dialysis. Since the insufficiency of active vitamin-D-metabolites plays an essential role in the development of the renal osteopathy, since 1978 in 13 patients undergoing dialysis a regular ultraviolet radiation has been performed, in order to stimulate the cutaneous vitamin-D-production.
