Outline of Final Research Achievements

We analyzed the cardiovascular responses to the low dose infusion of vasopressin using chronically instrumented premature fetal sheep (n=5). No significant difference in the tissue blood flow and vascular resistance of adrenal glands, kidneys, gut, heart and brain was found between before and after the vasopressin infusion.
We also succeeded to examine the correlation of the vascular resistance with resistance index detected by the Doppler ultrasonography before and after the vasopressin infusion in the premature fetal sheep (n=6), supported by the pumpless artificial placenta system. There was no significant correlation between the vascular resistance and resistance index in the middle cerebral and renal artery.
