...Daniel E. Warren; Donald C. Jackson SUMMARY To evaluate the role of mineralized tissues of the leopard frog in buffering acid, we analyzed the composition of femur and auditory capsule, the latter of which encloses a portion of the endolymphatic lime sacs, and investigated the extent to which...

... conspecifics in anoxic water. Much of the decrease in survival was attributable to a dramatically lower shell-bone content (44% ash in adult painted turtles vs. 3% ash in hatchlings of all three species) and a smaller buffer content of bone (1.3 mmol g –1 CO 2 in adult painted turtles vs. 0.13–0.23 mmol g –1...

... oxygenated red blood cells, but the nonbicarbonate buffer value for the red blood cells was unaffected by oxygenation. Plasma was not significantly different under oxygenated or deoxygenated conditions. Partitioning of CO 2 carriage in oxygenated and deoxygenated blood supports recent in vivo observations...

...Jon F. Harrison; Calvin J. H. Wong; John E. Phillips ABSTRACT The biochemical basis of buffering in the haemolymph of insects has received little attention, and the chemical complexity of insect haemolymph (reviewed by Mullins, 1985 ) suggests that the relative importance of various compounds...

...B. L. Tufts; R. G. Boutilier ABSTRACT Carbon dioxide transport and ion distributions were examined in the blood of the lamprey, Petromyzon marinus . Over the range studied, the erythrocytes had the highest total CO 2 content, followed by whole blood and true plasma. The nonbicarbonate buffer values...

High levels of phosphagens mean high proton absorption during hydrolysis and an increase in the intracellular buffer value. Decarboxylation reactions in catabolic pathways...

...James N. Cameron ABSTRACT Radioactive labelling of the CaCO 3 in the crab’s carapace was employed as a tool to study the contribution of the carapace carbonates to acute buffering of acid-base disturbances. Since Ca 2+ uptake is extremely rapid during the post-moult period, crabs that moulted...

...Donald C. Jackson; Norbert Heisler ABSTRACT The role of buffering of the high pericardial fluid [HCO 3 − ] of the turtle, Chrysemy spicta bellii Gray, was evaluated during prolonged anoxia at 3 and 10°C. At 3°C, pericardial fluid samples were collected from groups of animals after 0, 1, 2, 4 and 8...
