[Effect of adenosine on intravascular accumulation of leukocytes and tissue damage in striated muscle in endotoxemia].
Under the experimental conditions of endotoxinemia, the therapeutic use of an intravenous infusion of adenosine (110 micrograms x kg-1 x min-1) has been investigated in the microcirculation model of the BALB/c mouse. Injection of S. abortus-equi endotoxin (2 mg x kg-1 body wt. i.v.) elicited a significant increase of sticking leukocytes in postcapillary venules of striated skin muscle, which was associated with a swelling of microvascular endothelium and striated skin muscle. Infusion of adenosine effectively attenuated the endotoxin induced enhancement of leukocyte sticking and preserved microvascular endothelial and striated muscle integrity. These results imply the use of adenosine as therapeutic concept during endotoxinemia.
