Relaxation responses to (A) NS1619 (10−8-10−5 M) or (B) 14,15-epoxyeicosatrienoic acid (EET; 10−6 M) in isolated fetal coronary arteries from ewes fed a control (100%) or nutrient-restricted (60%) diet during the last ⅔ of pregnancy. Data are expressed as a percentage of the initial increase in tension induced by U46619 (3 × 10−9 M), which averaged 2.49 ± 0.3 and 2.20 ± 0.3 g in fetal coronary artery rings from ewes fed a control and nutrient-restricted diet, respectively (P > 0.05). Each point represents the mean ± SE; n = 4–5.
