RESUMEN
Objective To establish the systemic lupus erythematosus (SLE) mouse model through pristaneip injection and validate the model comprehensively.Methods Female BALB/c mice of 6-8 weeks were randomly divided into two groups.Animals in model group were injected with 0.5 mL pristane by ip injection while in control group with 0.5 mL normal saline.Anti-systemic lupus erythematosus antibodies (anti-SLE) and anti-double strand DNA antibodies (anti-dsDNA) were checked before injection and monthly thereafter.Proteinuria was detected before injection and every month thereafter.All mice were bled to death 6 months after injection.Kidneys were excised to observe the histopathologic evidence of glomerulonephritis.Results The concentration of anti-dsDNA and anti-SLE antibody in sera was higher of model group than that of control group two months after pristane injection,and the concentration of antibody gradually increased within 6 months.At the sixth months,the protein concentration of urine in most model group mice was ++++.The histopathology and imunoflorescence of kidney sections indicated typical evidence of glomerulonephritis in model group.Conclusion The murine lupus model can be successfully established in female BALB/e mouse with a single ip injection of 0.5mL ofpristane.
