Abstract:
:This study was undertaken to investigate the protective role of lactate on the hypoxic brain in newborn rats. A total of 107 7-day-old Wistar rats were divided into three groups. The lactate accumulation group was given 5% oxygen and 95% nitrogen for 30 minutes. The lactate elimination group was given 5% oxygen, a concentration of 7.5% carbon dioxide, and 87.5% nitrogen for 30 minutes. The control rats were placed in room air. Lactate levels in the brain tissue were higher in the lactate accumulation group than in those of the control group (control: 1.78 +/- 0.91, lactate accumulation: 11.42 +/- 1.64 mmol/kg) and significantly decreased in the lactate elimination group (4.10 +/- 1.73 mmol/kg). Blood pH remained at the same levels in the two groups. Neuron specific enolase in the cerebrospinal fluid, which is the initial neurocyte damage marker, was significantly elevated in the lactate elimination group (control: 18.3 +/- 7.5, lactate accumulation: 18.8 +/- 7.9, lactate elimination: 63.1 +/- 61.3 ng/mL). Brain adenosine 5'-triphosphate levels were significantly decreased in the lactate elimination group. Histologic findings of the brain at 72 hours after the load revealed no abnormal changes in any of the groups examined. The authors conclude that lactate accumulation plays a protective role on the hypoxic brain in newborn rats.
