Palmitoylethanolamide attenuates neurodevelopmental delay and early hippocampal damage following perinatal asphyxia in rats
Impaired gas exchange close to labor causes perinatal asphyxia (PA), a neurodevelopmental impairment factor. Palmitoylethanolamide (PEA) proved neuroprotective in experimental brain injury and neurodegeneration models. This study aimed to evaluate PEA effects on the immature-brain, i.e., early neuroprotection by PEA in an experimental PA paradigm. Newborn rats were placed in a 37◦C water bath for 19 min to induce PA. PEA 10 mg/kg, s.c., was administered within the first hour of life. Neurobehavioral responses were assessed from postnatal day 1 (P1) to postnatal day 21 (P21), recording the day of appearance of several reflexes and neurological signs. Hippocampal CA1 area ultrastructure was examined using electron microscopy. Microtubuleassociated protein 2 (MAP-2), phosphorylated high and medium molecular weight neurofilaments (pNF H/M), and glial fibrillary acidic protein (GFAP) were assessed using immunohistochemistry and Western blot at P21. Over the first 3 weeks of life, PA rats showed late gait, negative geotaxis and eye-opening onset, and delayed appearance of air-righting, auditory startle, sensory eyelid, forelimb placing, and grasp reflexes. On P21, the hippocampal CA1 area showed signs of neuronal degeneration and MAP-2 deficit. PEA treatment reduced PA-induced hippocampal damage and normalized the time of appearance of gait, air-righting, placing, and grasp reflexes. The outcome of this study might prove useful in designing intervention strategies to reduce early neurodevelopmental delay following PA...

Impaired gas exchange close to labor causes perinatal asphyxia (PA), a
neurodevelopmental impairment factor. Palmitoylethanolamide (PEA) proved
neuroprotective in experimental brain injury and neurodegeneration models.
This study aimed to evaluate PEA effects on the immature-brain, i.e., early
neuroprotection by PEA in an experimental PA paradigm. Newborn rats were
placed in a 37◦C water bath for 19 min to induce PA. PEA 10 mg/kg, s.c.,
was administered within the first hour of life. Neurobehavioral responses were
assessed from postnatal day 1 (P1) to postnatal day 21 (P21), recording the day
of appearance of several reflexes and neurological signs. Hippocampal CA1
area ultrastructure was examined using electron microscopy. Microtubuleassociated protein 2 (MAP-2), phosphorylated high and medium molecular
weight neurofilaments (pNF H/M), and glial fibrillary acidic protein (GFAP)
were assessed using immunohistochemistry and Western blot at P21. Over
the first 3 weeks of life, PA rats showed late gait, negative geotaxis and
eye-opening onset, and delayed appearance of air-righting, auditory startle,
sensory eyelid, forelimb placing, and grasp reflexes. On P21, the hippocampal
CA1 area showed signs of neuronal degeneration and MAP-2 deficit. PEA
treatment reduced PA-induced hippocampal damage and normalized the
time of appearance of gait, air-righting, placing, and grasp reflexes. The
outcome of this study might prove useful in designing intervention strategies
