Background:
In an animal model, neonatal exposure to sevoflurane induces neuroapoptosis, leading to memory deficits in adulthood. A recent study showed that resveratrol (20 mg x kg(-1)) prevent alcohol-induced cognitive deficits and neural apotosis in rat pups postnatally exposed to ethanol. We investigated if resveratorol prevent sevoflurane induced neuroapotosis.
Methods:
Six-day-old mice were divided into two groups: resveratorol and control groups. Pups were given resveratrol orally 24h and 1h before sevoflurane anesthesia. Anesthesia was maintained for 6h. After anesthesia, apotosis was evaluated by immunohistochemical staining for activated caspase-3. Western blot analysis for cleaved poly-(adenosine diphosphate-ribose) polymerase was performed to examine apotosis.
Results:
Neonatal exposure to sevoflurane induced severe neuroapotosis. There were no differences between control groups and resveratrol groups with regards to immunohistochemical staining and western blot analysis.
Conclusions:
Resveratrol did not prevent sevoflurane-induced neuroapoptosis in the neonatal mice brain.
