Objective To explore the influence of leflunomide on Janus protein-tyrosine kinase(JAK)/signal transducer and activator of transcription(STAT) signal transduction pathway in renal tissue of MRL/lpr lupus mice.

Effect of arsenic trioxide on anti-dsDNA antibody and lymphocyte subsets proliferation in splenic cells of lupus-prone MRL/lpr mice;

To investigate the effects of arsenic trioxide (ATO) on the expression of IFN-γ,IL-4 and Th balance in MRL/lpr mice in both early and later stage of the disease,young (3-month-old) and old (5-month-old) MRL/lpr mice were chosen for such experiment,each age group was then separated in 3 different sub-groups.

OBJECTIVE To investigate the effects of arsenic trioxide(ATO) on expression of cytokines and lymphocyte subsets proliferation in splenic cells of MRL/lpr mice.

ses activity in serum and urine of MRL/lpr mice with ageing and its significance;

To determine the distribution of IL-4,IFN-γand IL-17 in lacrimal gland lesions,submaxillary lymph nodes of MRL/lpr mice——a model for idiopathic dacryoadenitis,and investigate the level of IL-17 in serum and splenocyte culture supernatant of MRL/1pr mice.

In animal model,urinary protein content,liver and kidney function,kidney/body weight and spleen/body weight ratio,glomerular immunocomplex deposition and pathological changes of kidney,liver and spleen were evaluated in MRL/lpr mice with or without oral p38MAPK inhibitor.

The effect of astragalus polysacchrides on the antiphospholipid antibodies in SLE mice;
