| Abstract |
The principal osmotic constituents of eel (Anguilla anguilla) and lamprey (Lampetra fluviatilis) parietal muscle have been determined and summations of ions and nitrogenous constituents compared with those in the plasma. By ultracentrifuging eel muscle, analysing the muscle fluid and centrifuged muscle, and determining their extracellular fluid (inulin space) ion-binding in the cells was estimated as Na 60%, K 4.6%, Ca 67%, Mg 28%, Cl 46% and P 1.3%. Calculated osmolality of muscle exceeds that of the plasma, and this is discussed in relation to binding and other factors. (DBO) |
