Abstract:
Objective To further determine the inflammation?associated cytokine changes during endotoxin(LPS)tolerance. Methods Kun?ming mice were divided into groups. The endotoxin tolerance mouse model was established with repeated injection of LPS. Serum levels of tumor ne?crosis factor?α(TNF?α),interleukin?10(IL?10)and IL?17 were determined by ELISA assay. Results The serum concentrations of TNF?α,IL?10 and IL?17 were 2 261.49±1 090.28 pg/mL,7 780.42±2 320.04 pg/mL,and 27.28±13.76 pg/mL in the LPS control group,which were increased significantly compared to the normal healthy control group. The serum concentrations of TNF?α,IL?10 and IL?17 were 1 174.19±450.91 pg/mL, 1 293.26±520.85 pg/mL,and 22.26±11.44 pg/mL in the endotoxin tolerance group. Levels of TNF?αand IL?17 were further decreased by dexameth?asone treatment during LPS tolerance inducing,while the IL?10 level did not change significantly. Conclusion Compared to the status of endotoxin inflammation,levels of TNF?αand IL?10 decreased significantly,while levels of IL?17 were not significantly changed in the status of endotoxin toler?ance. Dexamethasone could further suppress TNF?αand IL?17 levels during endotoxin tolerance inducing.
