Our previous studies have shown that low concentrations (noncytotoxics) of antineoplastic agents modulate positively the dendritic cells, favoring their in vitro maturation and improving their antigen presenting function. The effects on colorectal cancer cells (HCT-116) were also investigated and we have observed an increased immunogenicity and susceptibility to cytotoxic T cells. Thereby, this study aimed to investigate the effect of 5-fluorouracil (5-FU) an azacitidine (AZA), in minimum effective and noncytotoxic concentrations on lymphocytes of healthy donors. In this study we have analyzed the cytotoxic effect of drugs at these concentrations as well as the proliferative ability of lymphocytes. In vitro production of IL-10 and IFN- has been also evaluated. We have observed that low concentrations of those chemotherapeutic agents are not cytotoxic for lymphocytes. However, the minimum effective concentrations (5-FU: 0,4100,088 e AZA: 0,7570,233; p<0, 05) have reduced the cell number. Proliferative activity of allogeneic lymphocytes in a mixed reaction (MLR) was not affected by the treatment. The cytokine production was not affected by the treatments, either. In conclusion, low concentrations of 5-FU and AZA has no deleterious effects on human peripheral blood lymphocytes and seems to be safe for combinatory administration with DC vaccines

This paper aims to base the thesis that the varied currents of the post-modern thought, in so far as have recourse to relativism to a greater or lesser degree, contribute to the legitimation of the religious education in public schools and, in a broader aspect, the religion in the public spaces. The methodological resource used to demonstrate the link between post-modern thought and religious education is the analysis at the historical and dialectical materialism perspective of publications produced to increase teachers on this discipline that is, in compliance with the Constitution, optional for students and mandatory for public elementary schools. The subject of this analysis is the learning content and has as prime concern to highlight the discourse of legitimation recurrent in authors when it is explicit in itself and explicit when it does not. The religious education in public schools as object of study allows us to understand the relationship between the post-modern thought, with its hegemony space within the human sciences and contextualized in the neoliberal economic environment, and the learning to learn pedagogies currently hegemonic in the educational landscape. We intend to contribute to the legal debate on laity, the philosophical debate on post-modernism and especially to the debate on the pedagogical theories in the educational fundaments.
