| Outline of Final Research Achievements |
In recent years, it has been reported that children with nasal obstruction such as sinusitis and allergic rhinitis are inferior in reading ability, memory ability, academic ability. In this study, we evaluated changes of hippocampus which is the center of memory learning function and memory/learning function, using mice with nasal obstruction. In addition to systemic effects such as a decrease in oxygen saturation in the blood and an increase in stress, the nasal obstruction during the growth period induce organic changes such as discordance of BDNF/TrkB signaling which is responsible for the growth and development of nerve cells in the hippocampus and a decrease in the number of nerve cells.
