[Effects of Andrographis paniculata component on nitric oxide, endothelin and lipid peroxidation in experimental
Objective:
To observe the effects of Andrographis Paniculata component (API0134) on nitric oxide (NO), endothelin (ET), cyclic guanosine monophosphate (cGMP), lipid peroxide (LPO) and superoxide dismutase (SOD) in experimental atherosclerotic rabbit.
Methods:
An atherosclerotic rabbit model was established by feeding high cholesterol diet supplemented by bovine serum albumin injection bolus. The rabbits were randomly divided into the control, model, and API0134 treated group. Blood samples were collected before 4 weeks and 8 weeks after relevent treatment.
Results:
Before 4 and after 8 weeks API0134 administration, compared with model group, the NO, cGMP and activity of SOD increased (P < 0.01), while LPO and ET decreased (P < 0.01).
Conclusions:
API0134 possesses the effects of antioxidation, preserving endothelial function, and maintaining the balance of NO/ET.
