Abstract
This paper reported the clinical effects and therapeutic mechanism of blocking agent of substance P (SP) nerves on perennial allergic rhinitis. We applied capsaicin (CAP) in the treatment of 50 cases of perennial allergic rhinitis once a week and 4 times as a therapeutic course. By using highly specific and highly sensitive SP radioimmunoassay, the SP contents in nasal secretions were determined before and after CAP therapy. The results showed that clinical symptoms of allergic rhinitis were obviously relieved and SP content in the nasal secretions was remarkably reduced from 29.444 +/- 14.280pmol/L before CAP therapy to 16.848 +/- 10.622 pmol/L after therapy (P < 0.001). Of the 50 cases, 35 cases (70.0%) showed the best effects, 12 cases (24.0%) better effects and 3 cases (6.0%) no effects. The total effective rate was 94.0%. The study indicated that therapeutic mechanism of CAP on perennial allergic rhinitis is related to the reducing of SP and the blocking of axonal reflex of the SP nerves.
