Do different assays for human acylated ghrelin concentrations provide comparable results?
We conclude that the two investigated techniques yield results with an acceptable agreement. The agreement of both measurements indicates a good external consistency and reliability of both analytical methods. In the absence of a gold standard for ghrelin measurement, our data are a cross-validation for both methods.
Pro-inflammatory cytokines (IL-1beta, IL-2, IL-6, IFN-gamma, TNF-alpha) in the plasma correlate with increasing pain intensity. Chronic pain patients show a significant increase in plasma levels of NO in comparison to healthy controls.
