    摘要: A method for in vivo, ex vivo and in vitro regeneration of cartilage, collagen and bone remodeling by intermittently applied hydrostatic pressure consisting of repeated periods of applied hydrostatic pressure followed and interrupted by periods of recovery. The intermittent hydrostatic pressure is applied at physiological levels 5-10 MPA for an interval of 4 hours followed by a recovery period up to about 20 hours. The interval loading results in the selective inhibition of matrix degrading enzymes, pro-inflammatory cytokines and chemokines that attract inflammatory cells into the joint cavity and in selective decrease of gene expression of growth factors that are inhibitory to type II collagen expression.
