Figure 4. Effect of lactate on the accumulation of FDG6P in rat hearts (determined by PET). Hearts were perfused with Krebs buffer plus 11 mM glucose (plus 125 MBq tracer ¹⁸FDG) for the first 100 min and subsequently perfused with Krebs buffer plus 11 mM glucose plus 10 mM lactate (plus 125MBq tracer ¹⁸FDG). Values are mean±SEM and are expressed in counts per second (cps), n=4 per group.
