FIG. 4.

Contusion volume was not significantly affected by the administration of 2.2 g/kg of glucose 15 min before injury. (A) A representative photograph of an animal brain from each group shows no visible difference in contusion volume (scale bar = 4.5 mm). (B) Histological measurement of contusion volumes in the animals further confirmed that hyperglycemia at the time of injury did not have a significant effect (vehicle, n = 4; glucose, n = 5; data are presented as mean ± standard error of the mean).
