title: Binding of inorganic mercury by subcellllar fractions and proteins of rat kidneys.
abstract: Inorganic mercury, administered to rats in a single dose of 0.5 mg Hg/kg is accumulated in the kidneys mainly in the soluble (54%) and nuclear (30%) fractions, showing decreasing tendency with time. Mitochondrial and microsomal fractions, initially accumulating approx. 11 and 6% of total Hg, show a tendency to increase the absolute level of Hg for the first week after administration. In the soluble fraction low-molecular weight, metallothioneinlike proteins are mainly responsible for the accumulation of mercury, in other fractions proteins of higher molecular weight prevail.
