Isotope Displacement in the Arc Spectrum of Platinum
WE have been engaged for some time upon the study of the fine structures of thirty-three lines of the arc spectrum of platinum in the region 6800–4320. We find that the odd isotope, 195, has a nuclear spin of ...

The effect of propylthiouracil on glutathione S-transferase activity of rat spleen in vitro and in vivo
Propylthiouracil (PTU) inhibited glutathione (GSH) S-transferase (EC 2.5.1.18) activity of rat spleens in a concentration dependent manner in vitro. PTU (1.5 mmoles/kg) treatment of rats for 1 or 2 weeks cause...
