研究目的(著者による)

To study whether a single millimeter wave treatment, that can produce opioid-related hypoalgesia, may also retard gut transit and colorectal passage in mice.

詳細情報

Endogenous and exogenous opioids are known to suppress gastrointestinal transit; the authors hypothesize that endogenous opioids are involved in millimeter wave treatment-induced hypoalgesia.

研究の主なアウトカム(著者による)

The data have shown that millimeter wave treatment does not significantly change small intestinal or colonic transit in mice. Thus, suppression of gastrointestinal motility should not be a setback in the clinical use of millimeter wave treatment.
