Abstract:
:During the inflammatory response, tissues release histamine (H), substance P, serotonin (5-HT), prostaglandins and kinins, agents that mediate manifestations of inflammation such as pain, vasodilation, increased capillary permeability and smooth muscle contraction. In this study we investigated whether racemic (R[+]) ketamine (K) and its isomers are spasmolytic on intestinal smooth muscle contracted by inflammatory mediators, and whether the spasmolytic effect of K is related to changes in calcium influx through the L-type calcium channel or to an interaction of K with opioid receptors. We measured the contractions of guinea-pig ileum mounted in an organ bath containing Tyrode's solution gassed with 95% O2/5% CO2 at 37 degrees C. In the first protocol we determined the effect of K and its isomers on contractions induced by five mediators: 10(-7) M H, 10(-8) M substance P, 10(-8) M neurokinin A, 5 x 10(-9) M bradykinin and 5 x 10(-7) M 5-HT. For each of these mediators, we plotted concentration-response curves for the inhibitory effect of K, and from regression fitting of these curves, we calculated the IC50 concentration of K that inhibited the contraction by 50%). In the second protocol we measured the contraction induced by the calcium ionophore A23187 (5.0 x 10(-6) M), both alone and after 1.8-7.2 x 10(-4) M R(+/-)K. Then we examined how the inhibition caused by R(+/-)K was affected by increases in the concentration of extracellular calcium by adding calcium (1.8-7.2 x 10(-3) M).(ABSTRACT TRUNCATED AT 250 WORDS)
