This study was carried out to determine the effects of Rho-kinase inhibitors, Y-27632 and fasudil, on the anticholinesterase (anti-ChE)-induced contractile and phosphatidylinositol responses of rat trachea. In vitro measurements of isometric tension and [^3H] inositol monophosphate (IP_1) formed were conducted by using rat tracheal rings or slices. Neostigmine- and pyridostigmine-induced contractions were almost completely inhibited by Y-27632 and fasudil at 30 μM for each, while acetylcholine-induced contraction was inhibited incompletely, i.e., by 56% by Y-27632 and by 51% by fasudil, at 100 μM for each, respectively. The inhibitory effects of fasudil on neostigmine- and acetylcholine-induced contractions were completely reversed by calyculin-A, a myosin phosphatase inhibitor. Neostigmine-induced IP1 accumulation was attenuated by fasudil at 100 μM. The results suggest that anti-ChEs cause airway smooth muscle contraction in part through activation of the Rho-kinase pathway.

本研究旨在观察Rho激酶抑制剂Y-27632和法舒地尔对抗胆碱酯酶（anti-ChE）诱导的大鼠气管收缩和磷脂酰肌醇反应的影响。用大鼠气管环或气管薄片进行离体等长收缩张力和[^3H]肌醇单磷酸（IP_1）形成的测量。Y-27632和法舒地尔（各30 μM）几乎完全抑制新斯的明和吡啶斯的明诱导的收缩，而乙酰胆碱诱导的收缩则不完全抑制，即，在100 μM时，Y-27632和法舒地尔分别降低56%和51%。法舒地尔对新斯的明和乙酰胆碱引起的收缩的抑制作用被肌球蛋白磷酸酶抑制剂calyculin-A完全逆转。100 μM法舒地尔可减弱新斯的明诱导的IP 1蓄积。结果表明，抗胆碱酯酶通过激活Rho激酶途径部分引起气道平滑肌收缩。
