[Serum neuraminic acid level in patients with cerebrovascular disorders].

The authors determined the level of neuraminic acid in the serum of 50 patients with encephalomalacia and 25 patients with cerebral haemorrhages on the 1st, 3d and 7th days of the disease. Twenty healthy subjects served as controls. A statistically significant rise in the concentration of this substance was observed in both groups of patients throughout the whole period of observations.
