| Outline of Final Research Achievements |
To develop the novel method for artificial control of glucose and lipid metabolism without exercise and drug, we investigated the effects of microstimulation of peripheral sympathetic nervous system on glucose and lipid metabolism. As a result of the microstimulation of sympathetic nerve fascicle in the unilateral sciatic nerve in rats, the stimulation enhanced systemic glucose uptake without change in plasma insulin level. In addition, the stimulation for 1 h elevated gene expression of Cox4 in epididymal adipose tissue in rats, suggesting increase in mitochondria. In conclusion, the microstimulation of peripheral sympathetic nerve fascicle enhanced non-insulin-mediated glucose uptake systemically and fat oxidation in adipose tissue.
