摘要

Objective: To observe the analgesic effect of Zhitong Capsule (ZTC) and study its mechanism in adjuvant arthritis (AA) rats.Methods: Forty-eight male Sprague-Dawley rats were randomly divided into six groups with 8 rats in each group. On the first day

except to those in the normal group that were treated with normal saline

the same amount of Freund’s complete adjuvant (FCA) was given through intradermal injection into the right hind paw to all the rats in the other groups. From the 17th day of the modeling on

the rats in groups of ZTC were administered daily through gastrogavage with a dose of 1000

500

250 mg/kg respectively

while equal volume of normal saline was given to those in the normal group and model group

and an equal volume of aspirin (ASA) solution was given to rats in the ASA group through gastrogavage for 10 days

once per day

and on the 27th day

the analgesic effect of ZTC was measured with heat withdraw method. The activities and contents of Superoxide dismutase (SOD) and lipid peroxides (LPO) in serum were observed by spectrophotometry

and the level of beta-endorphin (β-EP) in hypothalamus were determined by the assay of immunohistochemistry.Results: ZTC showed significant effects on enhancing the pain threshold and at the same time it increased the activities of SOD and reduced the contents of LPO in serum. ZTC could also increase the level of β-EP in hypothalamus.Conclusion: ZTC has analgesic effect and its mechanism is probably related with its effect in inhibiting the level of oxygen free radicals in serum and increasing the level of β-EP of hypothalamus in rats.
