Abstract

Prenatal stress is known to affect the offspring later in life. Lauric acid is a known antioxidant shown to play a protective role in experimental animals. This study examines the role of Lauric acid on sleep deprivation-induced stress on serum corticosterone level and birth weight in male rat pups. Pregnant dams were sleep-deprived using the modified multiple water platform for 20hrs daily from gestational day 9-19. Animals in groups 1 and 2 served as normal and stressed controls respectively, groups 3,4 and 5 received Lauric acid of doses 125mg/kg, 250mg/kg and 500mg/kg respectively while group 6 received Vitamin C 300mg/kg. Male offspring birth weight was recorded and at PND 28-36, were sacrificed and blood was collected for corticosterone assay. Serum corticosterone was significantly higher (p< 0.05) in the sleep-deprivation-induced stress group. Its level was also significantly lower (p<0.05) in the LA and vitamin C treated groups. Birth weight was significantly lower (p<0.05) in the stressed and vitamin C (300mg/kg) groups while being significantly higher (p< 0.05) in LA 125mg/kg group. This finding suggest that Lauric acid protect against rise in serum corticosterone level and improves birth weight in male offspring of dams subjected to sleep deprivation.
