The aim of this study was to determine the kinin responses on human umbilical artery (HUA) and to characterise the kinin receptors present on this tissue. The HUA was found to constrict in response to both the B2 receptor agonist, bradykinin (BK), and the B1 receptor agonist, des-Arg9-BK. The presence of indomethacin (2.79 microM) was found to have no significant effect on the responses to BK and des-Arg9-BK. The presence of the B2 receptor antagonist, HOE-140 (+2.79 microM indomethacin), resulted in a concentration-related rightward displacement of the concentration-effect curves to BK. The antagonism of the constrictor responses to BK by HOE-140 was found to be competitive (pA2 = 7.5). The responses to BK were not significantly affected by the B1 receptor antagonist des-Arg9(leu8)BK. The presence of des-Arg9(leu8)BK (+2.79 microM indomethacin) resulted in a concentration-related rightward displacement of the concentration-effect curve to des-Arg9-BK. The antagonism of the response to des-Arg9-BK by des-Arg9(leu8)BK was found to be competitive (pA2 = 5.9). The responses to des-Arg9-BK were not significantly affected by HOE-140. The results of the present study suggest that the products of the cyclooxygenase pathway are not involved in the kinin constrictor response on HUA and indicate the presence of B1 and B2 receptors on this tissue.

UI	MeSH Term	Description	Entries
D009119	Muscle Contraction	A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.

D009131	Muscle, Smooth, Vascular	The nonstriated involuntary muscle tissue of blood vessels.	Vascular Smooth Muscle,Muscle, Vascular Smooth,Muscles, Vascular Smooth,Smooth Muscle, Vascular,Smooth Muscles, Vascular,Vascular Smooth Muscles
D001920	Bradykinin	A nonapeptide messenger that is enzymatically produced from KALLIDIN in the blood where it is a potent but short-lived agent of arteriolar dilation and increased capillary permeability. Bradykinin is also released from MAST CELLS during asthma attacks, from gut walls as a gastrointestinal vasodilator, from damaged tissues as a pain signal, and may be a neurotransmitter.
