Abstract:
Objective:To investigate influence of Fludarabine to lupus activity of lupus mice and the effectiveness and safety of Fludarabine on the treatment of BXSB lupus mice and their possible methanism Methods:Fludarabine of 30 mg/(m 2?d) was injected into BXSB by tail vein,3 days continuously Results of treatment was observed through counting number of peripheral blood WBC Anti ds DNA and anti nuclear antibody in BXSB serum was measured by ELISA Pathologic transformation of kidney or urine protein was measured by immunofluorescence or urine protein test paper after treated by Fludarabine Expression of CD4 +Fas +?CD8 +Fas +?CD45RO + Fas + on T lymphocyte were measured by flowcytometry Results:The number of peripheral blood WBC of BXSB mice began to decline from the third day after treated by Fludarabine The lowest value 〔0 5?0 2)?10 9 L -1 〕of the number of peripheral blood WBC appeared on the seventh day and on the nineteenth day the number of peripheral blood WBC was up to 1 0?10 9 L -1 after treated by Fludarabine The falling of anti ds DNA and anti nuclear antibody in BXSB serum appeared on the fourteenth and twentieth one day after treated by Fludarabine, respectively Reduction of from +～++ turning?kindey immunofluorescence were 72 7% in group of Fludarabine Reduction of protein urine from ++～+++ turning ?～ - appeared on the twentieth one and twentieth eight days Reduction of expression of CD4 +Fas +?CD8 +Fas +?CD45RO + Fas + on T lymphocyte was obvious after treated by Fludarabine Conclusion:Fludarabine can evidently reduce the serum level of anti ds DNA and anti nuclear antibody of BXSB and reduce injury of kidney and formation of protein urine So Fludarabine may have good curative effect to severe SLE Fludarabine can reduce expression of CD4 +Fas +?CD8 +Fas +?CD45RO + Fas + on T lymphocyte,which may be one of methanism of Fludarabine to SLE
