Implication

Method studies potassium-42 transport in isolated dog muscles, revealing the complexities of capillary circulation.

Key Points

  • Investigate the transport mechanism of potassium-42 from blood to tissue in isolated skeletal muscles.
  • Isolated perfused muscles of dogs were used for experiments.
  • Blood flow and arteriovenous potassium-42 differences were measured.
  • Blood-tissue clearance was calculated using the Fick principle.
  • Experimental measurements conform well to theoretical predictions regarding blood-tissue clearance.
  • Variation in measured permeability-surface area product with blood flow indicates non-uniform capillary circulation.
  • A theoretical relationship linking blood flow and blood-tissue clearance was developed.
