[A rheological method of diagnosis of multiple sclerosis].

A new method for the diagnosis of disseminated sclerosis is suggested, based on the determination of the red cell suspension viscosity within the range of physiologic temperatures. Three viscosity peaks (maxima): at 35, 37-38 (the physiologic), and at 40 degrees C have been detected, probably corresponding to thermotropic phase transitions in red cell membranes. The curves reflecting the eta (t degrees C) dependence in disseminated sclerosis are characteristic of this disease and may be used as a test for the laboratory diagnosis of disseminated sclerosis.
