Research Topics

1. Opioid mechanism of the essential oil induced peripheral antinociception.

2. The analgesic mechanism of antidepressants against pain transmission.

Our group performs the development of new pharmaceuticals, protection, and therapeutics of various diseases by exploring the interaction between a variety of drugs and certain tissue component. Our objectives are to investigate the functional association between pain-induced behavioral response and molecular alterations in the nervous system, and to discover newly improved analgesics without side effects and in an animal model of chronic pain.
