| Outline of Final Research Achievements |
The subjects with olfactory disorders were randomly selected from among patients who received follow-up visits at the smell clinic at the Kanazawa Medical University Hospital and who gave written informed consent. The subjects were randomized to the nasal stimulation group or the oral stimulation group in the clinical trials with three months olfactory rehabilitation. The achievement ratio of self-training was not significantly different between the two groups. Olfactory thresholds were not improved after three months olfactory rehabilitation in both groups. The olfactory transport of nasally administered thallium-201 was reduced in the patients with olfactory disorders in clinical trials with olfacto-scintigraphy. Furthermore, the nasal transport of insulin-like growth factor-1 to the brain was inhibited in mice with the resected olfactory bulbs.
