Modulation of Vasodilator Response via the Nitric Oxide Pathway after Acute Methyl Mercury Chloride Exposure in Rats

Figure 2

Effect of methyl mercury chloride treatment on the vascular relaxation response to acetylcholine, isoproterenol, and sodium nitroprusside. Concentration-response curves to (a) acetylcholine (ACh), (b) isoproterenol (IP) and (c) sodium nitroprusside (SNP) in the aortas of rats untreated, treated with methyl mercury chloride (𝑛=10) precontracted with PE. The results (mean ± SEM) are expressed as percentage of the response to PE. 𝑡-test, *𝑃<0.05.
