| Outline of Final Research Achievements |
We have contributed to the search for substances that promote natural sleep from natural products, in research using electroencephalographic analyses of mice. But electroencephalographic analysis is not suitable as a screening assay method because it requires time-consuming, labor-intensive procedures prior to measurement and in analyzing the results. Therefore, we developed a new and easy in vivo assay method to screen sleeping substances using thermography. This assay method was focused on the changes in body temperature during sleep inducement. In this study, we use this novel assay method and search for sleep-promoting substances from natural products.
On the other hand, we also thought it might be possible to apply the method to Kampo formulae in order to determine the involvement of each crude drug component. In this study, the role of each crude drug in the activity of Yokukansan was evaluated.
