| Abstract |
|
Malaclemys terrapin transferred from fresh to saltwater show rapid increases in osmotic pressure of the blood within 3 days. Subsequently blood osmotic pressure continues to rise but the rate slows, until a stable level is reached at 25 days. Calculated osmotic pressure and observed values differ, a difference not due to Na, K, Cl, Mg, Ca, urea or uric acid, and there is a significant anion gap. Bladder urine follows similar kinetics, increasing osmotic pressure very rapidly for 3 days, then increasing more slowly until it becomes iso-osmotic with plasma at 25. Here also there is a large difference between calculated and observed osmotic pressure, and there is a significant cation gap. Bladder urine continues very low Na concentrations, but significant Cl. Ammonia and urea make up part of the differences between calculated and observed values, but by no means all of it.
