The effect of peptone shock on oliguric-hypertensive bladder reflex

The effects of peptone shock on changes in the arterial blood pressure, respiration and urine excretion induced by bladder distension were investigated in 8 anaesthetized female dogs. It was found that during shock when the arterial blood pressure reaches its lowest value no effect can be induced. Later on, when the arterial blood pressure rose to intermediate values the intensity of the reflex effects were proportional to the value of arterial blood pressure. After shock when the arterial pressure was normal again the reflex effects were slightly less intenisve than the control ones obtained before shock, and they were dependent on biochemical changes affecting the nervous centres participating in the reflex.
