ABSTRACT
OBJECTIVE@#To investigate anti-inflammatory and immunomodulation effects of different ecotype from Isatidis Radix growing in Gansu province.@*METHODS@#Mice were randomly divided into 6 groups (=11)and used the auricular swelling and paw edema to observe the anti-inflammatory effects of Isatidis Radix; Mice were randomly divided into 7 groups (=11) and through the gasbag synovitis model to observe the anti-inflammatory effects of Isatidis Radix; Mice were randomly divided into 6 groups (=11), the immunosuppressed model were established by injection of cyclophosphamide (CTX) to study the effects of Isatidis Radix on index of thymus, blood routine and cytokines.@*RESULTS@#Gansu different ecotype from Isatidis Radix could reduce the swelling of the mice auricle, paw edema and total protein, leukotriene B(LTB)and malonaldehyde(MDA) in airbag synovitis exudates, and upgrade serum levels of superoxide dismutase (SOD); Degrade the tumor necrosis factor-α (TNF-α) and upgrade the index of thymus, the number of red and white corpuscles, the level of interferon-γ (IFN-γ), interleukin-4 (IL-4) (<0.05, 0.01) of mice immunosuppressed model; Above the research of anti-inflammatory and immunomodulation, there were no significant differences between Isatidis Radix of Gansu different ecotype and tetraploid.@*CONCLUSIONS@#Different ecotype of Isatidis Radix has obvious functions in anti-inflammatory and immunomodulation, but there are no significant differences between Gansu different ecotype and tetraploid.
