[Effects of Lycium barbarum L and Drynaria fortunei J Smith on in vitro attachment and growth of human gingival fibroblasts on root surfaces].

In this study, the effects of Lycium barbarum L and Drynarna fortunei J Smith on in vitro attachment and growth of human gingival fibroblasts to root surfaces were investigated. The results revealed that the above herbs at dose of 1.25 mg/ml could improve attachment and growth of fibroblast, on the planed diseased root surfaces to a certain extent. When exposed to Lycium brabrum L cells on the diseased root surfaces increased markedly in number, with more even distribution, better spread, and more exuberant growth. Drynaria fortunei J Smith was not as potent as Lycium brabarum L. The results suggest that the two drugs may improve the formation of new attachment of periodontal tissue.
