Abstract The effect of milk extract of Semecarpus anacardium Linn. nut milk extract (SA) was studied to gain some insight into this intriguing disease with reference to collagen metabolism. Arthritis was induced in rats by injecting Freund's complete adjuvant containing 10mg of heat killed mycobacterium tuberculosis in 1 ml paraffin oil (0.1 ml) into the left hind paw of the rat intradermally. After 14 days of induction, SA (150 mg/kg body weight/day) was administered orally by gastric intubations for 14 days. Decreased levels of collagen and glycosaminoglycans (GAGS) components (chondroitin sulphate, heparan sulphate, hyaluronic acid) and increase in the levels of connective tissue degrading lysosomal glycohydrolases such as acid phosphatase, beta-glucuronidase, beta-N-acetyl glucosaminidase and cathepsin-D observed in arthritic animals were reverted back to near normal levels upon treatment with SA. The drug effectively regulated the uriniray markers of collagen metabolism namely hexosamine, hexuronic acid, hydroxyproline and total GAGS. Electron microscopic studies also revealed the protective effect of SA. Hence, it can be suggested that SA very effectively regulate the collagen metabolism that derange during arthritic condition.
