Abstract
The present invention provides an agent for treatment of arthritic diseases such as rheumatoid arthritis that has for its active ingredient a complex of hyaluronic acid and zinc. This complex synergistically inhibits proliferation of synovial cells and suppresses matrix metalloproteinase MMP-9, which is produced by synovial cells, as compared with its constituents, hyaluronic acid and zinc, alone.
