TY - JOUR AU - Shen Jian-fan AU - Lin Ya-fang AU - Wu Qian-ping PY - 2016 TI - Effects of morphine, pethidine and fentanyl on isolated rabbit trachea JF - Acta Pharmacologica Sinica; Vol 15, No 5 (September 1994): Acta Pharmacologica Sinica Y2 - 2016 KW - N2 - Effects of morphine, pethidine and fentanyl on tension of isolated rabbit trachea were measured by electric field stimulation. Findings obtained were: 1) Morphine 53 mumol.L-1 increased markedly the trachea contraction (P 0.05), but reversed the effect of morphine on the trachea. The results indicated that the excitation of morphine receptor in trachea may be one of the mechanisms of the contraction of the trachea. UR - http://www.chinaphar.com/article/view/6459
