The effects of central injections of adenosine analogs on blood pressure and heart rate in the rat.

Rats were implanted with chronic indwelling cannulae into the lateral cerebral ventricle. After recovery from surgery, acute experiments on blood pressure were conducted under methoxyflurane/nitrous oxide anesthesia. Rats were injected intracerebroventricularly with two adenosine analogs, 5'-N-ethylcarboxaminidoadenosine (NECA) and (-)-N-(1-methyl-2-phenylethyl)adenosine(L-phenylisopropyladenosine) (L-PIA), and the effects on blood pressure and heart rate recorded. Both analogs produced dose-related reductions in blood pressure and heart rate with L-PIA producing a more potent depression of heart rate than NECA. These effects on blood pressure and heart rate were antagonized by parenteral injections of caffeine. In separate experiments, the responses of blood pressure and heart rate to microinjection of NECA into the brainstem of rats anaesthetized with methoxyflurane/nitrous oxide were also examined. Microinjection of 2.7 nmol/kg into the fourth ventricle in the region of the area postrema produced a profound and long-lasting depression of blood pressure and heart rate. These results show that central injections of analogs of adenosine can influence the areas of the central nervous system involved in the control of cardiovascular function.[1]
