洛阳市第二医院报导红商陆根有扩瞳作用,可用做扩瞳药[1];程世祺报导“商陆中毒七例”,也均有瞳孔散大的表现。查阅其他文献,迄未发现红商陆或商陆科其他植物扩瞳作用的报导。我们对红商陆的扩瞳作用进行了初步研究,在动物实验中证明红商陆确有轻度扩瞳作用;根的扩瞳作用较强,茎和叶的作用均弱;水制剂的作用较强,醇制剂作用均弱;从根中分离之“结晶E”,也有扩瞳作用。 Luoyang City No. 2 Hospital reported that Hongshang Lugen has a pupil dilation effect and can be used as a diuretic agent [1]; Cheng Shiyin reported “seven cases of commercial land poisoning”, and all have a dilated pupil. Looking at other documents, no report on the pupil dilation of Pokeweed or other commercial plant species has been found. We have conducted a preliminary study on the pupil dilation of Pokeweed. In animal experiments, we have shown that Pleioblastus does have a mild pupil dilation; roots have a strong dilatation effect, and stems and leaves have weak effects; the role of aqueous agents Stronger, the effects of alcohol preparations are weak; the “crystal E” isolated from the roots also has a pupil dilation effect.
