| Abstract: | The effect of central nervous system imidazoline receptors activation on basal blood pressure level, heart rate and arterial baroreceptor reflex in steady state and aversive emotional tension was tested in experiments on alert WKY, SHR and white bastard rats. It was found that the brain imidazoline receptors activation led to arterial baroreceptor reflex rise (both in resting and in emotional tension) and caused an emotional stress pressor effects decrease. No data proving involvement of imidazoline receptors in functioning of the systems maintaining level of blood pressure, were found. |
