title: Increase in rat liver ribonuclease inhibitor levels during the neonatal period.
abstract: Alkaline ribonuclease (RNase) activity in nuclear, mitochondrial, and cytoplasmic fractions of rat liver is higher in newborn animals than in young adults. The level of cytoplasmic RNase inhibitor is low in newborn rat liver and increases more than two fold by 10 days of age.
