Abstract

Objective: To probe into the mechanism of the Chinese herbs with functions of reinforcing kidney and supplementing qi for preventing knee osteoarthritis of the rabbit.

Methods: Totally 72 healthy Japan long-ear white rabbits, aged 4 months, were randomly divided into 6 groups, blank group (A), model group (B), high dose Chinese herb group (C), middle dose Chinese herb group (D), small dose Chinese herb group (E), aminoglucose hydrochloride capsule control group (F), 12 rabbits in each group. All the rabbits in the groups, except the group A, were fixed with plaster cast for six weeks to establish rabbit knee osteoarthritis. At the same time of modeling, the different doses of Juanbi Capsules and aminoglucose hydrochloride capsule were administrated intragastrically in the group C, D, E, F, respectively, for 4 weeks, for preventive treatment. In the group B, the rabbit was administrated intragastrically with equal volume of normal saline to the medication groups, twice each day, in the morning and the evening, and in the group A, nothing was administrated. After modeling for 6 weeks, the joint fluid was taken and TNF-alpha, IL-1 and IL-6 contents were detected with ELISA method, and the articular cartilage was taken for macroscopic and microscopic examinations.

Results: In all the preventive treatment groups, the articular cartilage color changed to varying degrees with formation of osteophyte and bone cyst, superficial erosion on the chondral articular surface, and the cartilage defect reached to the mid layer in a part of specimens with cartilage exfoliation, but which in the extent were significantly lower than those in the model group. There were significant differences between the group A and B in TNF-alpha, IL-1 and IL-6 contents in the joint fluid (P < 0.05), indicating that the modeling is successful; and there were significant differences as group B compared with the group C,D, E, F, showing that TNF-alpha , IL-1 and IL-6 contents are decreased in all the medication groups; and significant differences between group C, D, E suggests that the increase of Chinese herb doses strengthened the effect of reducing TNF-alpha, IL-1 and IL-6 contents in joint fluid.

Conclusion: The Juanbi Capsule prevents osteoarthritis possibly through decreasing serum TNF-alpha, IL-1 and IL-6 contents.
