Salubrious effect of Semecarpus anacardium against lipid peroxidative changes in adjuvant arthritis studied in rats.
Oxygen derived free radicals are known to play an important role in the etiology of tissue injury in rheumatoid arthritis. The effect of milk extract of Semecarpus anacardium nuts at the dose level of 150 mg/kg body weight for 14 days on adjuvant arthritis was studied for gaining insight into the intrigue disease in relation to the lipid peroxidation and antioxidant defence system. Increased lipid peroxides' levels in both plasma and tissues (liver, kidney and heart) of adjuvant arthritis was significantly decreased by the administration of the drug. The antioxidant defence system studied in tissues of arthritic animals were altered significantly as evidenced by the decreased level of non-enzymatic antioxidants (GSH, vitamin E, vitamin C, NPSH and TSH) and enzymatic antioxidants (catalase and GPx except SOD). Administration of Semecarpus anacardium nut extract brings back the altered antioxidant defence components to near normal levels. These observations suggest that the diseased state of adjuvant arthritis may be associated with augmented lipid peroxidation and the administration of the drug may exert its antiarthritic effect by retarding lipid peroxidation and causing a modulation in cellular antioxidant defence system.
