Vasomotor reactions of the abdominal viscera at different arterial pressures

  • Published:
Bulletin of Experimental Biology and Medicine Aims and scope

Summary

A study was made of the vasomotor reactions of abdominal organs (the kidneys, spleen, intestine) by resistography in electric stimulation of the peripheral end of the splanchnic nerve with various intensity and frequency. It is shown that against the background of increased pressure, both vasodilatation and vasoconstriction occurred in lower intensity and frequency in comparison with the vascular reactions in the normal blood pressure level. Conversely, the thresholds of vasomotor reactions increase when the initial pressure level is diminished. This indicated that the vasomotor effects could be replaced by functionally opposite ones in the same nerve influences, depending on the initial state of vessels.
