Intraperitoneal injection of hypertonic glucose solution induced intracranial hemorrhage in rats. Simultaneously determined plasma norepinephrine exponentially increased followed by death. Using in vivo voltammetry, the present study was undertaken to estimate the relationship between neurochemical parameters and intracranial bleedings induced by hypertonic glucose injection. When placed in a solution of dihydroxyphenylacetic acid (DOPAC) and 5-hydroxyindole acetic acid (5-HIAA), electrically pretreated carbon fiber electrodes produced a 3 distinct peaks. Peak 1 and 2 refer to the extracellular fraction of ascorbic acid and DOPAC. Peak 3 refers to that of 5-HIAA. The peaks of the voltammograms obtained in vivo from different areas of the brain are similar to those observed in vitro using DOPAC and 5-HIAA solutions. Electrodes implanted in the ventricular CSF showed that DOPAC increased immediately after glucose injection, while 5-HIAA did not change significantly. When the electrode was inserted into the putamen, 5-HIAA exponentially increased followed by death, whereas DOPAC showed only a small change. It was presumed that the stroke-induced major oxidizable compounds are different in the lateral ventricle and the putamen. These results suggest that during cerebral bleeding, plasma norepinephrine increases accompanied with a potentiation of the central DOPAC and 5-HIAA system in rats.
