Effect of a new non-steroidal anti-inflammatory agent on lysosomal stability in adjuvant induced arthritis.

The effect of new non-steroidal anti-inflammatory agents on lysosomal stability was studied by determining the activity of beta-glucuronidase, a typical lysosomal enzyme, in various sub-cellular fractions and its release from the lysosome-rich fraction. Adjuvant arthritic animals showed a significant increase in the beta-glucuronidase activity in sub-cellular fractions. The increased rate of the release of beta-glucuronidase from lysosome-rich fraction clearly suggested that arthritic syndrome caused decreased stability of the lysosomes. Administration of boswellic acids or salai-guggal to arthritic animals was found to increase the lysosomal stability by inhibiting the rate of release from lysosome-rich fraction and reducing beta-glucuronidase activity in various sub-cellular fractions. Of the two anti-inflammatory agents tested, salai-guggal was found to afford more therapeutic value than boswellic acids.
