THE EFFECT OF DIFFERENTIAL REARING ENVIRONMENTS ON SELECTED BODY ORGANS OF MACACA MULATTA.
Abstract
Twenty-six male rhesus monkeys were sacrificed and organ pathology was completed. The following measures were taken: body weight, brain weight, thymus weight, adrenal weight, brain/body ratio, thymus/body ratio, adrenal/body ratio and gross and microscopic organ pathology. Differences between these measures based upon (1) early rearing experience and (2) shock-induced stress exposure were not significant. Intercorrelations between these measures were also computed; a number of them were found to be significant. Performance on a shock-escape match-to-sample task was found to correlate significantly with brain weight and brain/body ratio. Findings of this study do not agree with results of similar studies conducted on rats. (Author)
