This study was designed to evaluate the protective effects of eleutheroside B (EB) in high-altitude-induced myocardial injury (HAMI) and to unravel the underlying molecular mechanisms. SD rats were used for in vivo experiments. Following pretreatment with EB. the SD rats were exposed to a hypobaric environment within a hypobaric chamber for 48 h. https://www.truvisionhealthftp.com/
