Naoxintong Capsule (NXT), a Chinese medicine, has been widely used for the treatment of cardiovascular diseases in clinic. The present study was designed to clarify the effects of NXT on haemorheology, blood coagulation, hepatic function, antioxidant capacity and inflammatory responses in a rat model of blood stasis syndrome. Rats were placed in ice-cold water for 5 min during the time interval of two adrenaline injections to induce blood circulation disorders after intragastric administration of 10 consecutive days. Blood was collected from abdominal aorta to determine whole blood viscosity (WBV), plasma viscosity (PV), activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB), total antioxidant capacity (T-AOC), superoxide dismutase (SOD), malonaldehyde (MDA), alanine transaminase (ALT), aspartate transaminase (AST), interleukin-1β (IL-1β), interleukin-6 (IL-6), platelet activating factor (PAF). The results showed that NXT could significantly decrease the WBV, PV, FIB and prolong the APTT and PT. Meanwhile, NXT significantly decreased the serum contents of MDA, IL-1β, IL-6, ALT, AST and PAF, while elevating T-AOC and SOD levels. These results indicate that NXT could improve coagulation function, enhance antioxidant capacity and suppress inflammation, which might partly account for its mechanisms of action in preventing and treating cardiovascular diseases.
