Fig. 3. — Effect of ANG II (10⁻⁷ M) on vasoconstriction and [Ca²⁺]_i in mesenteric microvessels of Norm-Preg and RUPP rats. Simultaneous measurements of ANG II-induced changes in diameter and 340/380 fluorescence ratio were recorded in isolated microvessels from Norm-Preg (A, B) and RUPP rat (B, D). Bar graphs represent means ± SE of vasoconstriction and [Ca²⁺]_i measurements in 10 microvessels of Norm-Preg (E, G) and 9 microvessels of RUPP rats (F, H). *,†[Ca²⁺]_i (340/380 ratio) measurements in RUPP rat are significantly different (P < 0.05) from corresponding measurements in Norm-Preg rats.
