  • Abstract
  • Look Inside

Effects of a continous infusion of glycerol on the hypoxic rat were assessed by measurements of lo-cal cerebral glucose utilization and local cerebral blood flow using the quantitative autoradiographic 1-[C-14]-2-deoxyglucose and [C-14]-iodoantipyrine techniqes, respectively. Local cerebral glucose uti-lization of the hypoxic rat was decreased in most of cerebral structures except for the amygdala, sep-tal nucleus and the white matter. Local cerebral glucose utilization of the hypoxic rat treated with glycerol was recovered to the pattern of normal control, although glucose utilization of the nucleus raphe and locus ceruleus was accelerated. Cere-bral blood flow of the hypoxic rat was elevated in almost of all measured structures. In particular, blood flow in the substantia nigra and locus ceru-leus was increased significantly. The pattern of local cerebral blood flow of the hypoxic rat treated with glycerol was more analogous to that of normal control than of hypoxic rat without treatment. It is suggested that glycerol has beneficial effects by elevating local cerebral glucose utilization inhibit-ted and decreasing local cerebral blood flow over-shot on the hypoxic condition.
