Research Abstract |
Stimulation over the opening cartilage for temporomandibular joint in rats, promote the secretion of IL-1βin the mesenchymal layer of cartilage, reduced the proteoglycan of hyaline cartilage layer of the surface cartilage and hyaluronic acid. By irradiation of a rat model of LIPUS for the opening over, a decrease in IL-1βcompared to the non-irradiated group, the increase in proteoglycan On the other hand was observed. Suppressor pathway for IL-1βof LIPUS, LIPUS pathways inhibited the enhancement of COX-2 and ERK-1/ 2 by activating integrin under inflammation, called to suppress the IL-1βhas been suggested.
