Modulation of Tyrosine Hydroxylase, Neuropeptide Y, Glutamate, and Substance P in Ganglia and Brain Areas Involved in Cardiovascular Control after Chronic Exposure to Nicotine

Figure 2

Immunoreactivity of tyrosine hydroxylase, neuropeptide Y, and substance P in superior cervical ganglion (SCG) of Wistar Kyoto (WKY) and spontaneously hypertensive (SHR) rats exposed either to nicotine or placebo delivered through subcutaneously implanted pellets during 8 weeks. Values are presented as mean ± SD, * as compared to the same strain placebo treated rat; # as compared to WKY on the same experimental condition, according to 2-way ANOVA followed by Bonferroni posttest, .
