Background: Pogostemonis Herba, the dried aerial part of Pogostemon cablin Blanco, is a well-known materia medica in Asia that is widely used for syndrome of gastrointestinal dysfunctions. Objective: This study was undertaken to examine whether Pogostemon cablin extract (PCe) might have any beneficial effect on hypoxia induced rabbit cardiomyocyte injury. Materials and Methods: Isolated cardiomyocytes were divided into three groups and the changes of cell viability in cardiomyocytes of hypoxic and hypoxia/reoxygenation group were determined. The effect of PCe on reactive oxygen species (ROS) generation, intracellular formation of ROS was also measured by monitoring the 2',7'- dichlorofluorescein fluorescence. Results: PCe effectively protected the cells against both the hypoxia and reoxygenation induced injury, and the protective effect of PCe is not mediated by interaction with adenosine triphosphate-sensitive K + channels. In the presence of PCe, production of ROS under chemical hypoxia was remarkably reduced which suggests that PCe might exert its effect as a ROS scavenger. Conclusion: The present study provides clear evidence for the beneficial effect of PCe on cardiomyocyte injury during hypoxia or reoxygenation following prolonged hypoxia.
