a substance P antagonist (an experimental agent); they then measured natural killer cell activity in vitro.
No significant changes were observed in the verum period for the following types of cells: T- and B-lymphocytes, CD4+- and CD8+-T-lymphocytes including the subgroups of "naive" and "memory" CD4+- and CD8+-T-lymphocytes as well as the natural killer cells. Using a modified version of the Wilcoxon-Mann-Whitney-U-test, which is claimed to be optimal for the evaluation of the results of studies with a cross-over design, a significant difference was found for the number of CD8+-T-lymphocytes and natural killer cells corresponding to either a decrease during treatment with verum or an increase in the number of these cells in the placebo period.
