The NORs frequency in a group of newborns and adults was determined by the gelatine silver staining technique. A higher number of Ag-NORs (χ2 test, p<0.01) was found in adults than in newborns. The lack of correlation between cell proliferating rate index (PRI) and frequency of Ag-NORs let us suppose that the decrease of Ag-positive NORs in neonates could probably be due to factors different from cell kinetics. A non random distribution of Ag-NORs on the acrocentric chromosomes was also demonstrated: chromosome 21, in particular, showed the highest frequency, while chromosome 15, the lowest
