Keywords: | rats;asphyxia;erythropoietin;hypothermia;newborns | Issue Date: | 1-Oct-2013 | Journal: | Journal of Maternal-Fetal and Neonatal Medicine | Abstract: | Objective: Evaluation of neuroprotective effects of hypothermia, erythropoietin and their simultaneous use after perinatal asphyxia in newborn rats. Method: Histerectomy was performed to Wistar female rats on the last day of gestation. Perinatal asphyxia was induced by submersion of uterus containing pups in saline for 15min. After resuscitation, pups were randomized into 4 groups, 15 animals in each: G1-asphyxia; G2-asphyxia+hypothermia (rectal temperature 33°C for 1h); G3-asphyxia+erythropoietin (Darbepoetin-α 2.5μg, intraperitoneally) and G4-asphyxia+erythropoietin+hypothermia. Pups were sacrificed on 7th day of life and histopathological analysis of hippocampus was performed. Results: Measure of damage to dorsal, ventral and entire hippocampus was significantly lower in groups G2, G3 and G4 than in group G1 (p∼0.00; respectively). Measure of damage to hippocampus in group G4 was significantly lower than in group G2 (p=0.029). Conclusions: This study demonstrates that simultaneous use of hypothermia and erythropoietin has more expressed neuroprotective effects than sole use of hypothermia after perinatal asphyxia in newborn rats. © 2013 Informa UK Ltd.
