[Blood and plasma viscosity and the distance of intermittent claudication in patients with type II diabetes and thrombophlebitis].

In 49 patients with insulin-resistant diabetes, with ischaemia of the lower extremities blood viscosity was measured at low coagulation rates and plasma viscosity was determined also. Moreover plasma measurements were done of total lipids, alpha-, pre-beta-, and beta lipoproteins, triglycerides, total cholesterol, free fatty acids, and, besides that, the hematocrit was measured. Immediately after blood sampling for rheological and biochemical investigations the distance of intermittent claudication was measured. A rather considerable increase of blood and plasma viscosity was noted in the patients in comparison with controls, other findings included disturbances of lipid metabolism, increased fibrinogen level, and a negative correlation between the distance of intermittent claudication and blood and plasma viscosity.
