kinin
kinin[′kī·nən] (pharmacology) Any of several pharmacologically active polypeptides that act as hypotensives, contracting isolated smooth muscles and increasing capillary permeability; an example is bradykinin. kinin
kinin [ki´nin] the generic term for any of the polypeptides related in amino acid sequence and physiological activity to bradykinin and kallidin, formed by kallikrein-mediated cleavage of kininogens. Kinins are plasma proteins that increase vascular permeability, interact with prostaglandins to cause pain and smooth muscle contraction and to increase the migration of white blood cells during the inflammatory process, and act as potent renal vasodilators to increase the renal excretion of sodium.ki·nin (kī'nin), Polypeptide hormones that are released from diffuse stores and not from specialized tissue. they are rapidly inactivated at the site of release. [G. kineō, to move, + -in] kinin (kī′nĭn)n. Any of various structurally related polypeptides, such as bradykinin, that act locally to induce vasodilation and contraction of smooth muscle.ki·nin (kī'nin) One of a number of substances having pronounced physiologic effects. Some are polypeptides, formed in blood in various pathologic processes, which stimulate visceral smooth muscle but relax vascular smooth muscle, thus producing vasodilation. [G. kineō, to move, + -in]kinin One of a family of POLYPEPTIDES, released as a part of the inflammatory process, which increase the leakiness of small blood vessels and cause smooth muscle fibres to contract.kinin the old name for CYTOKININ.ki·nin (kī'nin) Polypeptide hormones released from diffuse stores and not from specialized tissue, rapidly inactivated at the site of release.
