Results T-2 toxin could cause rat articular chondroncytes degeneration, necrosis, and appeared many blank areas free cells. Weigert/Van Gieson staining showed obvious collagen fasciculi emergence could be seen. Scanning electronic microscope showed the surface of articular cartilage was wave and rough. Collagen fasciculi ruptured and stack up, and presented a typical 揳rticular dryness?phenomenon. ELISA results indicated, at the stage of 3 month, the level of rat serum CTX-II in T-2 toxin group was higher than that in control group, and the difference had a markedly significance.
