SUMMARY Potassium
(K+) fluxes across the placenta of rats, at 21 daysgestation, fed a low K”
diet or a control diet were studied. The rats on the low E? diet had a signtjicantly (I’ < 0.001) lower arterialplasma diet (1.95 + 0.12
K’ concentration compared to those on the control
and 2.93 + 0.06
mmol/l
respectively;
