...M. C. L. Phillips; C. D. Moyes; B. L. Tufts ABSTRACT The effects of cell age on metabolism in the nucleated red blood cells of rainbow trout ( Oncorhynchus mykiss ) were examined. Red blood cells were separated according to age using fixed-angle centrifugation. The mean erythrocyte haemoglobin...

Virkki; Annika Salama; Mikko Nikinmaa ABSTRACT We have measured the effects of oxygen tension on the transport of Na + , K + and Cl − across the erythrocyte membrane of the lamprey Lampetra fluviatilis . The transport of each ion was affected by the oxygen tension of the medium. Hypoxic...

Gusev ABSTRACT The existence of a furosemide-sensitive Cl − transport pathway activated by external Ca 2+ and Mg 2+ has been demonstrated previously in studies of Cl − influx across the lamprey erythrocyte membrane. The aim of the present...

...T. G. Pottinger; I. Brierley ABSTRACT Binding sites for the steroid hormone cortisol, with characteristics typical of a steroid receptor, were detected in the rainbow trout ( Oncorhynchus mykiss ) erythrocyte. Binding of [3H]cortisol to a washed and purified erythrocyte suspension was saturable ( B...
