ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of Shenmai Injection (SMI) and aminophylline on small airway smooth muscle cell (SASMC) apoptosis and the Fas/FasL expression in the papain induced emphysema model rats.</p><p><b>METHODS</b>Emphysema model in rat was established by a single intratracheal instillation of papain. Apoptosis and Fas/FasL expression of SASMC were examined by immunohistochemical SABC and TUNEL assay at 1, 3, 5, 7, 15 and 30 days after modelling, and the effect of SMI and aminophylline on them were observed.</p><p><b>RESULTS</b>Fas, FasL expressions in normal SASMC were very low with a positive rate of (2.31 +/- 0.05)% and (1.28 +/- 0.47)% respectively. After papain instillation, the positive rates increased along with the prolonging of instillation time. SMI showed an inhibition on SASMC Fas and FasL expression but aminophylline didn't show. SASMC apoptosis was very low in normal rats with a rate of (0.87 +/- 0.32)%, it also raised after papain instillation and increased progressively along with the instillation time. SMI treatment could lower the apoptosis rate but aminophylline couldn't.</p><p><b>CONCLUSION</b>Fas and FasL participated the SASMC apoptosis modulation in emphysema formation. SMI shows a definite treatment effect on emphysema by influencing the Fas and FasL protein expression and reducing SASMC apoptosis through inhibiting the release of inflammatory mediator.</p>
