Bee Venom Therapy May Help Treat Arthritis

Study Data from Sungkyunkwan University Provide New Insights into Arthritis
Drug Week, 12/15/2006

According to recent research published in the journal Toxicology In Vitro, "The effect of bee venom acupuncture (BVA) (api-toxin) on the development of type II collagen (CII)-induced arthritis (CIA) in rats has been studied. We have compared the levels of activity of a comprehensive range of cytoplasmic, lysosomal and matrix protease types, together with the levels of free radical-induced protein damage (determined as protein carbonyl derivative) in synovial fluid from CIA-treated, BVA-treated and normal rats."

"Many protease types showed significantly increased activity in CIA compared with normal rats. BVA (5 and 10 microl/100g) significantly reduced these enzyme activities by some 80% each, but levels of plasma proteases activity (including those enzyme types putatively involved in the immune response, such as dipeptidyl aminopeptidase IV and proline endopeptidase) in CIA, BVA (5 microl/100g)-treated and normal plasma samples were not significantly different. The level of free radical induced damage to synovial fluid proteins was approximately three-fold higher in CIA compared with normal rats.

However, BVA (5 microl/100g) significantly decreased the level of reactive oxygen free radical species (ROS) induced oxidative damage to synovial fluid proteins. It was concluded that activation of proteolytic enzymes and free radicals are likely to be of equal potential importance as protein damaging agents in the pathogenesis of rheumatoid arthritis (RA), and the development of novel therapeutic strategies for the latter disorder should include both protease inhibitory and free radical scavenging elements…

The researchers concluded: "BVA is considered to be an effective RA modulator, inhibiting protease activities and removing ROS."
