[The effect of intravenous glucose load on levels of glucose and fructose and activity of glucose-6-phosphate isomerase in serum of patients with subarachnoid hemorrhage].

The purpose of the study was to evaluate the effect of glucose load on changes of glucose and fructose concentrations in the blood and phosphohexose isomerase activity (PHI) in the serum of patients with subarachnoid haemorrhage. The investigation was applied to 20 patients with subarachnoid haemorrhage. The control group included 20 individuals. In patients with subarachnoid haemorrhage the intravenous load of hypertonic glucose solution resulted in the extended blood hyperglycaemia and the decrease of fructose concentration in final moments of test in the III, VII and XIV day of illness. The activity of phosphohexose isomerase remained normal both before and after the glucose load.
