Objective: To investigate the effectiveness of total glucosides of paeony (TGP) on Sjogren's syndrome (SS) using non-obese diabetic (NOD) mice model.
Study design: Twenty-seven 8-week-old female NOD mice were assigned into TGP group, hydroxychloroquine (HCQ) group and normal saline (NS) group, receiving corresponding drugs respectively and sacrificed at 24-week-old. Saliva flow rate (SFR), ration of regulatory T cells, level of anti-SSA/SSB, histological changes in submandibular glands (SMG) and microarray analysis were assessed. The data were analyzed using SPSS.
Results: Compared to NS group, in TGP group, SFR, SMG index and the ration of regulatory T cells were significantly higher, while anti-SSA/SSB and lymphocytic foci were significantly lower. HCQ group demonstrated similar results except SMG index. Altered gene expression was found in 10.71% of TGP and 13.09% of HCQ of the profile.
Conclusion: TGP demonstrated a similar effectiveness as HCQ in delaying the onset of SS-like disease in NOD mice.
