[Blood serum viscosity in patients with advanced vascular forms of vibration disease]

In 35 persons afflicted by advanced angioneurotic vibration syndrome, with no contact with mechanical vibrations for the past several years and recognized invalidity due to vibration disease, specific and reduced blood serum viscosity have been determined, as well as total protein concentration and albumin to globulin concentrations ratio. Control groups were composed of 32 healthy subjects, with no contact with vibration or any other environmental hazards, as well as of 57 professionally active subjects, afflicted by angioneurotic vibration syndrome. A significant increase in specific and reduced viscosity in the group with advanced angioneurotic vibration syndrome, as compared to both the remaining groups, was found. At the same time, the albumin-globulin concentrations ratio was found to be decreased, the total protein concentration remaining unaltered.
