Secretory immunoglobulin A (sIgA) in saliva and cardiovascular reactions to mental arithmetic and cold pressor tasks were recorded in 16 healthy young men on two sessions, 4 weeks apart. Both tasks elicited significant increases in sIgA secretion rate, reflecting increases in both salivary volume and sIgA concentration. Whereas mental arithmetic elicited a mixed pattern of alpha- and beta-adrenergic cardiovascular reactions, the pattern of reactions to cold pressor was predominantly alpha-adrenergic. Task levels of sIgA secretion rate, sIgA concentration, and saliva volume showed moderate to high test-retest reliability (r = .52-.83), although test-retest correlations were less impressive for change scores (r = -.19-.53). The pattern of correlations between change in sIgA secretion rate and cardiovascular reactivity variables was inconsistent.
对16名健康年轻男性进行了两个阶段的记录，两阶段相隔4周，记录了他们唾液中的分泌型免疫球蛋白A（sIgA）以及对心算和冷加压任务的心血管反应。两项任务均引起sIgA分泌率显著增加，这反映了唾液量和sIgA浓度的增加。心算引起了α-和β-肾上腺素能心血管反应的混合模式，而冷加压反应模式主要是α-肾上腺素能。sIgA分泌率、sIgA浓度和唾液量的任务水平显示出中度至高的重测信度（r = 0.52 - 0.83），尽管变化分数的重测相关性不那么显著（r = -0.19 - 0.53）。sIgA分泌率变化与心血管反应性变量之间的相关模式并不一致。
