(A, B and C). Bar graph showing the overall mean of % drop in renal cortical blood perfusion in response to NA (A), PE (B) and ME (C) in Control, LVH, Control-H2S and LVH-H2S groups rats during saline, 5-MeU low dose and 5-MeU high dose phases. Values are mean± SEM of n = 6 rats in each group. * P<0.05 vs. Saline phase of same group and # P<0.05 vs. 5-MeU low dose phase of same group. ϕ P<0.05 vs. respective phase of Control and Ψ P<0.05 vs. respective phase of LVH groups.

(A, B and C). Dose response curve of renal vasoconstriction responses to set of doses of NA (A), PE (B) and ME (C) in Control, LVH, Control-H2S and LVH-H2S groups rats during saline phase, low dose phase and high dose phase of 5-MeU. Values are mean± SEM of n = 5–7 rats in each group. The significance is overall mean of 4 graded doses (each dose response is averaging the ascending and descending order responses) of an agonist in each phase and compared to saline phase and high dose phase. * P<0.05 vs. Saline phase and # P<0.05 vs. 5-MeU low dose phase.
