Kim, Y.P., Yoon, J.H., Jeong, I.G., Choi, D.G., Lee, G.Y., Kim S.S., Shin, M.S., Kim, C.J., Effect of endurance exercise on nitric oxide synthase expression in hippocampus of rats. Exercise Science 11(2): 359-370, 2002. The effect of endurance exercise on nitric oxide synthase expression in the dentate gyrus, CA1, CA2 and CA3 of the hippocampus was investigated via nicotinamide adenine dinucleotide phosphate -diaphorase (NADPH-d) histochemistry. Male Sprague -Dawley rats were randomly divided into the three groups: the control group, the low-intensity exercise group, the moderate-intensity exercise group n=8 in each group. Animals of the exercise groups were put on running for 30min once a day, 5 days per week for 4 weeks. The regimen of the low-intensity exercise consisted with running at speed of 3 m/min for the first 5 min, 5 m/min for the next 5 min, then 8 m/min for the last 20 min, while the regimen for the moderate-intensity exercise was made with running at speed of 16 m/min for the first 5 min, 19 m/min for the next 5 min, then 22 m/min for the last 20 min. In the present results, weight gain of the rats in the moderate-intensity exercise group was significantly decreased compared to the control group and mild-intensity exercise group. In the moderate-exercise intensity group, NOS expression was significantly than lower the control and low-intensity exercise group in the dentate gyrus (p<.001), CA1 (p<.01), CA2 and CA3 (p<.001). It can be suggested that endurance exercise may prevent cell damage by inhibiting NOS expression of hippocampus. |
