Background
Thromboangiitis obliterans (TAO), also known as Buerger's disease, is an occlusive arterial disease; however, the pathogenesis of TAO is still unclear. Research has shown that traditional Chinese medicine (TCM) has significant advantages in the treatment of TAO. Our
Conclusions
Our results suggested that integration of NP or MFS and NDDM could relieve the symptoms of TAO model rats induced by sodium laurate, which might provide a new management strategy for TAO.
Methods
We administered rats with 10 mg/mL sodium laurate to establish a TAO model, and then the TAO model rats were treated with notoginseng powder (NP), maifusheng (MFS), or the combination of NP or MFS and NDDM. Gangrene classification and blood rheology were evaluated; the pathological characteristics of rat limbs were examined by hematoxylin and eosin (H&E) staining and Masson staining; and cluster of differentiation 3+ (CD3+) and cluster of differentiation 20+ (CD20+) levels were measured by immunohistochemistry (IHC) and flow cytometry. In addition, inflammation-associated cytokines were analyzed by quantitative reverse transcription polymerase chain reaction (RT-qPCR), western blot, and enzyme-linked immunosorbent assay (ELISA).
Results
Integration of NP or MFS and NDDM dramatically reduced the gangrene classification and affected blood rheology parameters of TAO model rats compared with NP and MFS alone. Meanwhile, NP or MFS in combination with NDDM decreased CD3+CD20+ T cells, reduced thrombosis and inflammatory cell infiltration, and dramatically decreased the levels of inflammation-associated cytokines. Conclusions: Our results suggested that integration of NP or MFS and NDDM could relieve the symptoms of TAO model rats induced by sodium laurate, which might provide a new management strategy for TAO.
