Abstract:To study the protective effects of radix astragali against anoxic damages to in vitro cultured neurons in rats, NaCN was used to develop a hypoxic model of in vitro cultured neurons from newborn rat cerebral cortex. The cellular morphology, A value (cell survival number) and effluxes of lactate dehydrogenase (LDH) and K+ from cells were measured in the radix astragali group and the control group respectively. After 48 h of anoxia, A value was decreased from 0.325 +/- 0.031 before anoxia to 0.145 +/- 0.011, the… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
