title: [Dehydrogenase activity of pentose and glucuronate pathways of glucose utilization in the rat brain during single and repeated cooling].
abstract: Repeated supercoolings down to rectal temperatures (19-20 degrees C) results in the different changes in the dehydrogenase activity of pentose and glucuronate pathways in the rat brain: the activity of the pentose cycle oxidative enzymes (glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase) lowers considerably and that of VDP-glucose dehydrogenase rises. The dehydrogenase activity in the pentose cycle is found to be inhibited in rats cooled for the first time, the UDP-glucose dehydrogenase activity being preserved at the control level. In the adapted rats the cooling causes mobilization of the pentose cycle, the UDP-glucose dehydrogenase activity remains unchanged.
