LEVELS OF GLYCOLYTIC-ENZYMES AND METABOLITES IN THE RED-BLOOD-CELLS OF THE RED-LEGGED PADEMELON, THYLOGALE-STIGMATICA (MACROPODIDAE, MARSUPIALIA)

1. Haematology, red cell enzymes and metabolites and the rates of laca te production by the red blood cells incubated with different substrat es were measured in the blood from a small marsupial, the red-legged p ademelon (Thylogale stigmatica). 2. In comparison with other marsupial s of similar body weight, pademelon red cells have lower levels of ade nosine triphosphate (ATP) and a lower activity of glutathione S-transf erase. 3. Red cells incubated with inosine did not produce lactate, a finding which is not uncommon in marsupials.
