The return of 6 juvenile mangabey monkeys to their social group following an absence of a year resulted in increased basal cortisol secretion for both the offspring and the mothers and in significant decrements in the absolute number of lymphocyte subsets for the offspring. Six 9-month-old sooty mangabeys were removed from their socially housed mothers, subsequently peer housed, and returned to the maternal social group 1 year later. Offspring showed a significant increase in cortisol levels 24 hr following reunion (48 +/- 6%) and this difference persisted through 1 month, while the mothers showed a significant increase only at the 24-hr sample point (18 +/- 3%). Moreover, the offspring, but not the mothers, showed a significant decrease in lymphocyte subsets which were evident through the 1-month sample point. Behavioral data revealed a significant positive correlation between the percent of total scan samples offspring were with their mothers (proximity, contact, huddle) the day of return and the offspring's percent change from baseline in total T cells 24 hr later, r = 0.84. All mother-offspring pairs with the exception of one exhibited frequent affiliative behaviors toward one another by 6 days following the return. These data demonstrate that the reunion of juvenile mangabeys with their mothers after a year's absence is an acute stressor for the mothers and a relatively longer term stressor for the offspring, and that behavioral interactions which characterize the return of individual subjects to the natal group can predict acute physiological responses.
6只幼年白眉猴在离开一年后回归其社会群体，这导致后代和母亲的基础皮质醇分泌增加，且后代淋巴细胞亚群的绝对数量显著减少。6只9个月大的乌白眉猴被从与其共同生活的母亲身边带走，随后与同伴一起饲养，并在1年后回归母亲的社会群体。 reunion后24小时，后代的皮质醇水平显著升高（48±6%），这种差异持续了1个月，而母亲仅在24小时采样点时皮质醇水平显著升高（18±3%）。此外，后代而非母亲的淋巴细胞亚群显著减少，这种情况在1个月的采样期内都很明显。行为数据显示，回归当天后代与母亲在一起（接近、接触、依偎）的总扫描样本百分比与24小时后后代总T细胞相对于基线的变化百分比之间存在显著正相关，r = 0.84。除一对外，所有母婴对在回归后6天内都表现出频繁的亲和行为。这些数据表明，幼年白眉猴与母亲在分离一年后团聚，对母亲来说是一种急性应激源，对后代来说是一种相对长期的应激源，而且个体回归出生群体时所表现出的行为互动可以预测急性生理反应。
