COMPARISON OF RENAL AND CARDIAC LYMPH CONSTITUENTS

MJ Keyl, RT Dowell, AA Yunice

Abstract


The concentration of various substances were meas·
ured in renal and cardiac lymph and arterial and
venous plasma to determine if lymph constituents
might indicate events occurring at the cellular level
in these two organs. The study utilized anesthetized
dogs. Magnesium, calcium, pyruvate and glucose
concentrations were similar in the four fluids. Cardiac
lymph contained significantly higher concentrations
of creatine phosphokinase, lactic dehydrogenase
and lactate. Renal lymph contained lower concentrations
of zinc and protein while both renal and cardiac
lymph contained less copper than arterial plasma.
Venous plasma contained more copper than the
other fluids. It is concluded that lymph composition
reflects events occurring in the cells, especially
for substances that are not readily diffusable through
blood capillary endothelium.
