Bioactive peptide from bee venom for adjuvant-induced arthritis in rats / 中国组织工程研究

ABSTRACT

BACKGROUND: Traditionally, bee venom can treat rheumatic arthritis,rheumatoid arthritis(RA) and so on, but it has strong side effects. So it has been hoped for a long time that the effective angle component could be screened from bee venom, which can be used for the treatment of arthritis perfectly than bee venom.OBJECTIVE: To investigate whether bioactive peptide from bee venom could inhibit infection of arthritis by regulating immunological function so as to probe into a new treatment for RADESIGN: Completely randomized controlled experimental trial based on experimental animalsMETHODS: A municipal key laboratory of animal biology.MATERIALS The experiment was carried out in the Chongqing Key Laboratory of animal biology from January 2001 to May 2002. Totally 80 rats of clean grade aged 2 to 3 months old with the body mass of 180 to 200 g were provided by Animal Experiment Center of Third Military Medical University of Chinese PLA. The experimental animal certification number was SYXK1 (army) 2002 -007. The animals were divided into 3 groups normal control group( 10 cases), arthritis group( 10 cases), bioactive peptide group(30 cases).METHODS: Adjuvant-induced arthritis animal models were used and bioactive peptide were given to the animals by muscle injection to observe the knuckle volume and knuckle index changes.MAIN OUTCOME MEASURES: The effect of bioactive peptide from bee venom on the change of knuckle volume and knuckle index in adjuvant-induced arthritis ratsRESULTS: Ten days after injection of 0. 15 mg for each rat, the volume of the paw was (4.72 ±0. 58) mL and the knuckle index was (4.47 ±0.46) mL,which there was significant difference compared with the control group (P＜ 0. 05).CONCLUSION: P-peptide possibly has certain inhibitory effect on the development of the adjuvant-induced arthritis in Wistar rat, and will possibly be a potential therapeutic drug.
