Figure 4. Fetal arterial blood pressure responses to increasing doses of AII at 138-139 days in fetuses infused with vehicle from 125 days gestation (open bars), metyrapone from 125 days gestation (filled bars) or with metyrapone from 137/138 days (grey bars) gestation.

Different letters above the bars denote mean arterial BP responses which are significantly different from other values within a treatment group (P < 0.05).
