Lead(Pb)is ubiquitous in the environment,and low-level Pb exposure can cause neurotoxicity and irreversible damage to children’s cognition,learning and memory ability.Nutritional intervention is an effective method to prevent Pb poisoning.Mulberry is rich in anthocyanins,possessing protective effects for nerves.This study investigated the neuroprotective effects of mulberry extract(ME)against Pb-induced learning and memory deficits in mice.The results showed that the learning and memory abilities of mice,assessed using the Morris test,improved significantly after treatment with ME at a dose of 100 mg/kg body weight.The level of Pb in the brains of mice in the three ME intervention groups decreased significantly,while NO production and anti-oxidant enzymes were significantly restored.It is suggested that ME inhibits Pb-induced neurotoxicity by reversing Pb-induced alterations in the aspect of neurotoxic effects and improving learning and memory.

Nutritional intervention is an effective method to prevent Pb poisoning. Mulberry is rich in anthocyanins, possessing protective effects for nerves.

The results showed that the learning and memory abilities of mice, assessed using the Morris test, improved significantly after treatment with ME at a dose of 100 mg / kg body weight. The level of Pb in the brains of mice in the three ME intervention groups decreased significantly, while NO production and anti-oxidant enzymes were significantly restored.
