[Erythrocyte aggregation indicator, hematocrit and plasma viscosity in patients with a vascular form of vibration...

In 82 men suffering from the vascular form of the vibration disease divided by its advancement into two groups: group I of 42 persons (aged, on average, 40 +/- 7.5) at an early stage of the disease and group II consisting of 40 persons (aged, on average, 49.7 +/- 5.6) at an advanced stage of the disease--haematocrit, plasma viscosity and red-cell aggregation indices were determined. The control group (III) was composed of 100 healthy, average--hard working, men (aged, on average, 41.3 +/- 8.4). In those suffering from the vibration disease the red-cell aggregation and plasma viscosity were found to increase, the rise being more intense in group II.
