体内研究 | Triamcinolone hexacetonide produces a marked, dose-dependent protective effect in the model of chemically induced articular cartilage damage. Guinea pig injected with Triamcinolone hexacetonide shows much less prominent fibrillation and osteophytes. Cell loss is less extensive. A single injection of Triamcinolone hexacetonide into the ipsilateral knee of rabbits which have been subjected to partial lateral meniscectomy and transection of the sesamoid and collateral fibular ligaments reduces chondrocyte cloning, loss of cells, osteophyte formation, and fibrillation. The half-life of commercially available Triamcinolone hexacetonide in the vitreous is double that of Triamcinolone hexacetonide, but the former is toxic to the retina in this rabbit model. Reformulated iso-osmolar Triamcinolone hexacetonide shows no evidence of deleterious effects to retina function or structure. Local application of Triamcinolone hexacetonide at a site of lingual nerve injury leads to changes that are potentially beneficial such as reduced mechanical sensitivity and enhanced regeneration. |
