RESUMO
AIM: To study the dynamic changes of levels of serum interleukin-18 (IL-18) and tumor necrosis factor-alpha (TNF-alpha) in children with infectious mononucleosis (IM). METHODS: 72 patients with IM were analyzed for the expression of TNF-alpha and IL-18 by RIA and ELISA, respectively in acute phase, convalescent phase, (the first month, the third month, the sixth month), and the control group. RESULTS: The levels of serum TNF-alpha and IL-18 in patients with IM were significantly higher than that in control (P < 0.05). The serum levels of TNF-alpha and IL-18 decreased with time and in patients at stage were significantly higher than that in control (P < 0.05). The levels of serum cytokine were correlated with the state of illness. CONCLUSION: The serum cytokine TNF-alpha and IL-18 may be regarded as index to reflect the state of immunity and prognosis of patients with IM.

One-pot synthesis of novel phosphoramidates with porphine and nitrogenous drug was accomplished. In the absence of light, MTT test showed that they killed the BEL-7402 liver cancer cells effectively in vitro. The cell viability studied on normal liver and cancer cells showed that porphine phosphoramidates selectively kill the cancer cells, which was in sharp contrast with the non-porphine containing compound 4-formylphenyl N,N-bis(2-chloroethyl)-phosphoramidate. These results, coupled with the cell uptake test showing that they could differentiate the tumor cells from the normal cells by their selective accumulation in cancer cells, gave strong support to the notion that the introduction of porphine moiety in these molecules was responsible for the effectiveness and cell differentiability of these porphine phosphoramidates.
