Figure 7: The effect of SF2 on calcium-induced contraction in isolated rat aortic rings prepared in calcium-free Kreb's solution. (a) The comparison of contraction recorded in rings incubated with norepinephrine hydrochloride in the presence of SF-2 (treatment group) and in the absence of SF-2 (control group). (b) The effect of ethylene glycol tetraacetic acid incubation on SF-2-induced relaxation. The ratio of contraction 1 (contraction in the aorta incubated with and without SF-2 in the presence of ethylene glycol tetraacetic acid) and contraction 2 (contraction in the aorta incubated with and without SF-2 in the absence of ethylene glycol tetraacetic acid) is presented in b. Values are expressed as mean ± SEM; **showing the difference of treatment group with control at the significance value P < 0.01. SEM: Standard error of the mean
