| Outline of Final Research Achievements |
We investigated the age-related regression of the tibial nerve and capillary, and the effects of the aerobic exercise to aged tibial nerve and capillary. The myelinated fibers and capillaries in the tibial nerves of elderly group significantly atrophied and deceased in comparison with those of young rats. The tissue and serum BDNF (promoting factor of repair and survival of myelinated fiber) of aerobic exercise (Ex) group (2 weeks) significantly increased and decreased in comparison with those of control (Con) group, respectively. In contrast, the tissue and serum VEGF (promoting factor of angiogenesis) of Ex group significantly decreased and increased in comparison with those of Con group, respectively. According the above results, it has been revealed that both the peripheral nerve and capillary are able to survive and regenerate with complementary relation.
