Extract

Reactive oxygen species (ROS) play an important role in lupus nephritis. It has been known that nuclear factor kB(NFkB) is activated by ROS, and binds to KB element in nucleus. Afterwards, inflammatory cytokines are translated and produced in lymphocytes, macrophages and glomerular cells in the kidney. In this study, we investigated the role of ROS and NFkB p65 in the pathogenesis of lupus nephritis (MRL lpr/lpr mice) by the histochemical and immuno-electron microscopic methods.

A modified Brigg’s method was used to determine the generation of H2O2 in the renal tissue of lupus mice. Tissue samples were incubate in 0.1 MTris maleate buffer (pH 7.4) with 7% sucrose, 1mM CeCl3 and 10 mM aminotriazole at 37 °C for 30 min. After completion of the cytochemical reaction, tissues were fixed in 2% w/v glutaraldehyde in 0.1 M cacodylate buffer (pH 7.4) at 4 °C for 60 min.
