RESUMO

Objective:To observe the effects of zinc supplementation on the function of brain after sleep deprivation(SD).Methods:Rats SD model was made by the “Flower Pot" technique.Three days later,the rats received Y-labyrinth test to test the function of learning and memory.NADPH-d histochemistry and ABC immunohistochemistry were applied to exam the activity of NOS and the levels of protein expression of nNOS in hippocampus of rats.Results:Compared with the normal group,Learning times of rats in Y-labyrinth test of the SD group increased(89.3?25.3 /67.1?29.3,t=1.81,P0.05).Compared with the SD group,in TZC supplementation group,the levels of NOS in sub-area of hippocampus(CA_1:27.2?2.8;CA_3:15.3?1.6;DG:21.8?1.9,P0.05).Conclusions:TZC supplementation can improve learning and memory function of rats,and the mechanisms might be related to increased level of NOS and the protein expression of nNOS in hippocampus of animals.
