Efficacy of Siddha formulation Kalpaamruthaa in ameliorating joint destruction in rheumatoid arthritis in rats
Abstract
Rheumatoid arthritis (RA) is a kind of chronic inflammatory autoimmune disease. The degradation of extracellular matrix and cartilage pave way in understanding the molecular mechanisms in RA. Degradation of cartilage is a more complex event involving the local release of metallaoproteases and lysosomal enzymes that mediate inflammation in joints and in the synovial fluid in RA. In the present study, the efficacy of a Siddha preparation named Kalpaamruthaa (KA) in ameliorating the disease process via markedly reducing the joint destruction was demonstrated in adjuvant induced arthritis rat model. KA consists of Semecarpus anacardium nut milk extract (SA), dried powder of Emblica officinalis fruit and honey. Both SA and KA were administered at dose of 150 mg/kg b.wt. for 14 days after 14 days of adjuvant injection in rats. The activity of lysosomal enzymes, the level of collagen, glycosaminoglycans (GAGs) and its degradative products were analyzed in control and experimental animals. The study revealed that KA exhibited a profound reduction (p<0.05) in the activities of lysosomal enzymes and thereby decreasing (p<0.05) the levels of GAGs and its fractions when compared to arthritis rats. The latter was confirmed by Safrannin O st...Continue Reading

Autoimmune Diseases
Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
Anti-inflammatory Treatments
A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here
