✦ Synopsis

Skate and stingray cells were shown to hemolyze in isosmotic solutions containing urea as the sole solute. The rate of urea penetration into these cells as determined by the rate of hemolysis is highly temperature dependent with a Qlo of 2.50-2.75. A reduced rate of methylurea penetration i n the presence of urea was reconfirmed. The present results are consonant with the hypothesis of carrier mediated transport of urea in elasmobranch erythrocytes previously proposed by Murdaugh, Robin and Hearn.

In 1978, Kusik and Meissner (1978) presented an equation for the prediction of activity coefficients in aqueous electrolyte solutions, based on parameter q. In this work the temperature dependency of the Kusik-Meissner parameter, q, was studied. Although the activity coefficients of electrolytes ar
