FIG 2.

Drug-induced changes on in vitro apoptotic cell death and intracytoplasmic cytokine profile of peripheral blood mononuclear cells (PBMC) from healthy subjects. The results are presented as the means ± SEM of exposure index (EI = value for treated cultures/value for control cultures) of PBMC measured from cultures treated with BZ, K777, PYR, and FUR from NI subjects (n = 18). Statistically significant differences between populations undergoing the same treatment are represented by a solid black line. Significant differences for the same population between different treatments tested compared to BZ are represented by a gray rectangle.
