The concentration of digoxin in the cerebrospinal fluid (CSF) of ten patients receiving conventional oral doses of this cardiac glycoside has been measured by a radioimmunoassay technique. Digoxin was undetected in eight patients and barely detectable in two, suggesting the presence of a significant blood-CSF barrier for digoxin. The implication of these findings is discussed.
采用放射免疫分析技术测定了10例接受常规口服剂量这种强心苷的患者脑脊液(CSF)中地高辛的浓度。8例患者脑脊液中未检测到地高辛,2例患者仅能勉强检测到,提示地高辛存在显著的血脑屏障。讨论了这些发现的意义。
