Human and dog and rabbit skin blood vessel strips give contractile responses to catecholamines, serotonin, and angiotensin II. Alpha receptors for catecholamine can be demonstrated. Species and organ variations occur in the small vessel tissue response to bradykinin (dog), histamine (rabbit) and acetylcholine (lung). A prostaglandin‐contractile activity could be demonstrated on cutaneous vessels. This activity was most marked in dog paw vessels and rarely occurred in human skin. Potentiation of catecholamine by prostaglandin E‐, A‐ and F‐ contractions could be demonstrated. The prostaglandin receptor was not blocked by alpha or beta blocking agents. The prostaglandin response was related to calcium concentration and was unrelated to exogenous or endogenous cyclic AMP.
