METHODS: The vasodilatory effects of pinacidil and nifedipine were studied on rat aorta rings precontracted with 10 μmol·L -1 norepinephrine or 80 mmol·L -1 potassium chloride respectively.

Our experiment showed that addition of benzydamine induced vasorelaxation in the denuded aorta precontracted with KCl in the normal krebs.

实验结果亦显示，benzydamine能抑制高钾所引起的收缩作用，并且藉由在无钙之Krebs溶液中，经benzydamine前处理的血管给予高钾刺激之后，再给予钙离子刺激血管收缩，发现其能抑制外钙内流所造成的血管收缩作用。

Dilatiry of AS on rat thoracic aorta strips precontracted by noradremaline（1μmol/L）and KCl（30mmol/L）were proved.

结果 AS松弛去甲肾上腺素（1μmol/L）和氯化钾（30mmol/L）预收缩的大鼠胸主动脉条，其EC 50 分别（35.9±3.1）和（36.7±3.1）μmol/L。

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.

结果：①SO_2衍生物对去甲肾上腺素预收缩的内皮完整和去除内皮的大鼠胸主动脉血管环均呈浓度依赖性舒张作用，且其张力变化在内皮完整与去内皮的血管环之间无显著性差异；②SO_2衍生物可引起血管组织中cAMP、6-Keto(即PGI_2)含量剂量依赖性增加，其增加程度与内皮无关；③SO_2衍生物对血管环cGMP含量呈降低趋势但在统计学上无显著意义，且对去除内皮血管无显著影响；④SO_2衍生物对去内皮或内皮完整血管环的TXB_2含量均无明显影响；⑤无论是否去除内皮，SO_2衍生物均可引起cAMP／cGMP和6-Keto／TXB_2比值显著升高。

Acclimatization 1.73±1.82** 0.61±0.06 0.98** P＜0.01 vs normoxic rats.After the aorta preparations were precontracted with NE at the concentration of 0.62 μmol/L, a ccumulative vasodilative effects of ACh were tested.

与常氧对照组相比，急性低氧和间断低氧习服后，大鼠主动脉对ACh各浓度(10- 9～10-5 mol/L)引起的舒张反应显著减弱(P＜0.01)，其最大舒张分别为常氧对照组的87.3％和79.7％，其EC50值分别为1.34和1.73 μmol/L，分别为常氧对照组EC50值0.20 μmol/L的6.7和8.6倍(表2)。

Methods. Six 1-month-old cales underwent left-sided thoracotomies, exposing the anterior thoracic spine and aorta.
