[Rapid determination of 137Cs in environmental samples--purification of 137Cs by ammonium molybdophosphate column separation].

A rapid method for the determination of 137Cs in environmental samples was proposed. The principal technic employed in this study is based on column separation of 137Cs using ammonium molybdophosphate mixed with glass fiber to eliminate contribution of natural radionuclides such as 40K and 87Rb. The separation of cesium from potassium and rubidium was performed by the elution with 0.

[Subarachnoid hemmorrhage and aneurysmal change of cerebral arteries due to metastases of chorioepithelioma (author's transl)].

An episode of subarachnoid hemorrhage was seen on a 22-year-old married woman, which followed vaginal spotting and convulsive seizure. The neurological examination revealed bilateral papilledema, retinal hemorrhage, neck stiffness, Kernig's sign abducens paresis on the right. The chest X-ray film showed a spherical mass lesion in the right lung.
