Our major research works are conducted by use of several kinds of animals (mouse, rat, dog etc) as in vivo experiments. Additionally, molecular biological experiments using cultured cell system in vitro for physiological evaluation.

Integrative analysis of the autonomic nervous system as system control
Electric signals from anesthetized and/or conscious animal are detected in sympathetic nerves for integration.

Biological evaluation of safety for carbon nano-tube
Biocompatibility of carbon nano-tube has been evaluated mainly using mice.
