Tetrahydropalmatine has a therapeutic effect in a lipopolysaccharide-induced disseminated intravascular coagulation model

OBJECTIVES: The aim of this study was to determine the therapeutic effects of tetrahydropalmatine (Tet) on disseminated intravascular coagulation (DIC) by exploring the role of Tet using a lipopolysaccharide (LPS)-induced DIC model. Methods/Materials: We established a mouse DIC model by injecting LPS. Hematoxylin-eosin (HE) staining was performed to detect liver and kidney damage. Blood samples were obtained to determine liver and kidney injury indexes, coagulation indexes, and inflammatory cytokines. An in vitro cell inflammation model was also established. Tumor necrosis factor-α (TNF-α) levels and nuclear factor kappa B (NF-κB) signaling pathway activation were determined by western blot. RESULT: Tet ameliorated the damage to organ tissues, improved coagulation indexes, and reduced the inflammatory cytokine production in LPS-induced mouse DIC. Tet also inhibited TNF-α expression by suppressing NF-κB signaling pathway activation in an in vitro LPS model using RAW 264.7 macrophages. CONCLUSIONS: Tet has a mitigating and therapeutic effect on the LPS-induced DIC model via anticoagulant and anti-inflammatory effects, showing its potential as an adjunct to DIC treatment.
