Gill resistance (Rg) and oxygen transfer (To2) were measured in perfused rainbow trout gills. After perfusion the gills were analysed morphometrically. 2. Rg increased with 40% and To2 decreased with 91% during 60 min perfusion without vasoactive substances in the perfusion Ringer. 3. In presence of 10 micro M adrenaline both Rg and To2 remained stable at their starting levels throughout the experimental period (60 min). 4. With 0.2 micro M acetylcholine and 10 micro M adrenaline in Ringer Rg increased nearby to the same extent as in perfusions without vasoactive agents, while To2 was not significantly affected. 1 micro M acetylcholine increased Rg with 76% and decreased To2 with 51%. 5. The changes in Rg and To2 could be explained by structural changes in the secondary lamellae.

在灌注的虹鳟鱼鳃中测量鳃阻力（Rg）和氧转运（To2）。灌注后，对鳃进行形态计量学分析。2. 在灌注林格液中无血管活性物质的情况下，在60分钟灌注期间，Rg增加了40%，To2降低了91%。3. 在存在10微摩尔肾上腺素的情况下，在整个实验期间（60分钟），Rg和To2均保持在其起始水平稳定。4. 在林格液中加入0.2微摩尔乙酰胆碱和10微摩尔肾上腺素时，Rg的增加幅度与无血管活性药物灌注时相近，而To2未受到显著影响。1微摩尔乙酰胆碱使Rg增加了76%，To2降低了51%。5. Rg和To2的变化可以用次级鳃小片的结构变化来解释。
