Abstract:
Objective To investigate the effects of 1,25-dihydroxy vitamin D3 [1,25 (OH)2D3] on immune mechanism of RBC and spleen in colitis model mice.Methods Thirty mice were randomly grouped as follows:blank control group,model group and 1,25(OH)2D3 group.The animal models were established.Then the general condition and colon pathological changes in mice were observed,the changes of the RBC immune compound(RCIC) and RBC surface C3b receptor(RC3bR) wreath were detected by the yeast wreath method,the weight and length of spleen were measured,the positive rates of spleen immune cells were detected by flow cytometry.Results Compared with the model group,RBC-C3bR in the 1,25(OH)2D3 group and blank control group was significantly increased and RBC-ICR was significantly decreased (P＜0.01).Compared with the blank control group,the positive rates of CD3,CD4,CD8 and CD45R in spleen mononuclear cell were significantly increased (P＜0.01);after the 1,25 (OH) 2D3 intervention,the positive rates of CD3,CD4,CD8 and CD56R in spleen mononuclear cells were significantly decreased compared with the model group(P＜0.01).Conclusion 1,25(OH)2D3 has the immune regulatory effect on RBC and peripheral spleen lymphocytes in chronic colitis mice.
