Blood flow through the femoral artery, lymph flow in a lymphatic vessel in the femoral triangle and metatarsal distal venous pressure were measured simultaneously in a canine moving hind limb.
Low intra‐arterial doses of adrenaline and noradrenaline increased lymph flow even in the presence of marked arterial vasoconstriction. In contrast, isoprenaline increased arterial blood flow without affecting lymph flow rate.
Phenoxybenzamine, dihydroergotoxine, and nicergoline did not inhibit the lymphatic flow increase induced by adrenaline at doses active on arterial or venous vascular alpha‐adrenoceptors.
Propranolol given intra‐arterially into animals pretreated with alpha‐adrenoceptor blocking agents restored the vasoconstrictor effect of adrenaline (reversal of adrenaline reversal).
