title: The influence of aging on lysosomal acid DNase of the rat submandibular gland.
abstract: Lysosomal and cytoplasmic fractions were prepared from rat submandibular glands for investigation of the release of lysosomal acid DNase in relation to aging. It was found that the acid DNase activity ratio for cytoplasmic/lysosomal fractions in rats aged 27 months was higher than that in three-month-old rats. The release of acid DNase from the lysosomal fraction by shaking was markedly increased in the fraction from the older animals.
