[Comparative study of the anticoagulant activity of dimethoxyphosphates of rare-earth elements]

It was shown in experiments on rabbits that dimethoxyphosphates of rare-earth elements injected intravenously displayed a marked anticoagulant activity. The highest effect was produced by compounds of neodymium, holmium, terbium, europium, thulium, dysprosium, and erbium.
