Vasorelaxant and Antihypertensive Effects of Bergenin on Isolated Rat Aorta and High Salt-Induced Hypertensive Rats

Figure 2

A representative tracing. (a) shows the response of norepinephrine (NE) and acetylcholine (ACH) on MAP and (b) reveals the % increase and fall in BP of normotensive rats. (c) shows the response of NE and ACH on MAP in both normotensive and hypertensive rats. (d) A representative tracing showing the effect of bergenin on BP in normotensive anaesthetized rats. The bar graph (e) shows the fall in MAP produced by bergenin in normotensive and hypertensive rats.  < 0.05 and  < 0.01 describe the significant differences.
