Summary

Isolated gills of the freshwater mussel,Ligumia subrostrata, accumulate Na from a pondwater bathing medium. The rate of Na transport by the isolated gill is 13.2±1.1 μmol (g dry gill·10 min)−1 which equals or exceeds the estimated Na transport rate of intact animals. Sodium influx is saturable with aV max of 13.6±1.2 μmol (g dry gill·10 min)−1 and an affinity (K s) of 0.17 mM Na/l. The isolated gills survive prolonged exposure to pondwater with a constant\(\dot V_{O_2 }\) of 890 μl O2 (g dry gill·h)−1 over a 4 h period. Sodium transport in the isolated gills is stimulated 80% above control values by 10−4 M serotonin, 60% by 0.5 mM cAMP and 60% by 12.5 μg/ml nystatin. Sodium influx is inhibited by 0.5 mM amiloride and 1 mM lithium.
