CONTEXT: Traditional Herbal Medicine (THM) has many advantages that make it a promising choice for the treatment of ischemic heart disease (IHD). To study the mechanism of IHDs or pharmacological actions of THM, many hypoxia-induced cardiomyocyte injury models have been established. Radix Salvia miltorrhiza (Danshen) was used as a representative of THM. Danshen is a famous medicinal herb widely applied in Asia to relieve ischemic cardiovascular diseases. OBJECTIVE: To investigate the effects of various hypoxic conditions and discuss a suitable hypoxia model, cell viability, apoptosis, release of myocardial injury markers, and mRNA levels of target genes were tested for the first time. MATERIALS AND METHODS: Radix Salvia miltorrhiza (Danshen) was purchased from a GMP-compliant producer and both its preparation method and quality control were standardized. Cellular status, such as cell viability, apoptosis, releases of myocardial injury markers, and the mRNA level of target gene were tested by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) method, biochemical analyzer, flow cytometry, Hoechst 33258 staining, and real-time PCR, respectively. RESULTS: Based on our data, we found a treppe response of cardiomyocyte in the hypoxic condition and suggested that 8 h in 2% O2 might be a suitable condition for in vitro pharmacological study of cardiomyocytes. DISCUSSION AND CONCLUSIONS: Our findings outlined more extended and in-depth capability of cardiomyocyte suffering from hypoxia, and might be of particular interest due to the high prevalence of THM pharmacological study.
