Sažetak
Transduodenal transfer of calcium-45 was studied in eight-week-old female albino rats by the in vitro method of »everted gut sac« in the presence of lead nitrate in the incubation media. Lead concentration ranged from 0 (control) to 1000 µmol/L. Although it showed a tendency to decrease, calcium transfer was not significantly influenced by 20 and 40 µmol Pb/L, whereas it was significantly inhibited by concentrations exceeding 100 µmol Pb/L. Inhibition was inversely proportional to lead concentration: from 60 per cent of the control at 100 µmol Pb/L to 10 per cent at 1000 µmol Pb/L.
