[Glucose, pyruvate and lactate concentrations in the cerebrospinal fluid in patients with cerebral infarction].

The determinations were performed in cerebrospinal fluid of 50 patients with recent cerebral infarction in the 1-st, 3-rd and 10-th day of disease. Spectrophotometrie methods were used for the determination of lactate and pyruvate and a colorimetric method for glucose determination. A statistically significant increase of glucose in the cerebrospinal fluid on the 1-st day after cerebral infarction and of pyruvate, lactate and lactate: pyruvate index on 1-st and 3-rd day after cerebral infarction was found. The results obtained point to intensification of the anaerobic pathway of glucose metabolism.
