Our results indicated that (1) aortic rings with and without endothelium precontracted by NE to decreased pH induced a relaxation; aortic rings with and without endothelium to increased pH induced a contraction; there is no significant difference in presence and absence of endothelium .(2)NO levels had no significant change in isolated aortic rings presence and absence of endothelium to decreased pH and increased pH ;(3)sulfite levels in isolated aortic rings with endothelium reduced to decreased pH and increased pH. sulfite levels in aortic rings without endothelium had no remarkable change.

结果：①NE预收缩后，pH值降低对内皮完整和去除内皮胸主动脉血管环呈舒张作用；pH值升高对内皮完整和去除内皮胸主动脉血管环呈收缩作用；内皮完整组与去内皮组相比无显著性差异；②pH降低和升高对内皮完整和去除内皮血管环中NO含量无显著性影响；③pH降低和升高均可使内皮完整血管组织中亚硫酸盐含量减少，对去内皮血管中亚硫酸盐无显著性影响。

Our results indicated that (1)SO_2 derivatives could dose-dependently relax the isolated aorta rings with or without endothelium precontracted by NE, no difference was found for the rings with and without endothelium;(2)Levels of cAMP and 6-Keto(PGI_2) in isolated aortic rings were increased by SO_2 derivatives in a dose-dependent way, which were independent of endothelium;(3)SO_2 derivatives decreased cGMP levels in the rings, but not significantly; The decrease of cGMP levels was also independent of endothelium;(4)No changes of TXB_2 in rings with or without endothelium were observed;(5)Whether presence or absence of endothelium, cAMP/cGMP and 6-Keto/TXB_2 ratios were increased significantly.

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
