[Effect of an increase in blood osmotic pressure on the lymphodynamics of growing animals].

Experiments in puppies 1 day to 3 months old demonstrated that an increase in blood osmotic pressure produced lymph flow deviations (modified in their turn by changes in respiration) in neonatal animals. An increased lymph flow, a reduced arterial pressure and the antidiuretic response become obvious at the 2-3-month age resembling the reactions found in adult dogs. The lymphatic system of growing animals makes an important contribution to the regulation of osmotic balance through compensation for the functional immaturity of kidneys.
