Abstract:
Objective To observe toxic effect of deoxynivalenol(DON)on articular cartilage and synovium of New Zealand rabbits's knee ioints.Methods Fifteen male rabbits were divided randomly into 3 groups:control, high-dosage,and low-dosage group.In high-dosage and low-dosage group,saline solution of DON was injected with a dose of 0.10 and 0.05 ms/kg every 48 h into ear vein of rabbits.Specimen of articular cartilage and synovium were through pathologY methods,and IL-1β,TNF-α,NO levels were assayed in joint liquid,after 20 days. Results Morphological changes were observed, such as synovium inflammative infiltration, chondrocytes deformation and necrosis under light microscope.The levels of IL-1β,TNF-α and NO had statistical significance in comDarison between 3 grouPs(F=19.396,18.195,22.136,P＜0.05).The levels of IL-1β,TNF-α and NO were significantly higher(all P＜0.05),high-dosage[(0.451±0.091),(0.575±0.122)μg/L;(70.27±11.53)μmol/L] and low-dosage group[(0.295±0.107),(0.387±0.131)μg/L;(45.32±12.24)μmol/L]compared with control ((0.1 13±0.049),(0.138±0.087)μg/L;(23.56±9.35)μmoL/L],and high-dosage compared with low-dosage group Conclusions DON results in articular and synovial impairment,which has the symptom similar to osteoarthritis. DON probably causes osteoarthritis.
