A method is described by which tritium-labeled alltrans retinoic acid of high specific activity (up to \(\sim 51\) \(\mathrm{Ci} / \mathrm{mmol}\) corresponding to \(85 \%\) of theoretical) is converted photolytically within a fraction of a second to a mixture of retinoic acid stereoisomers. One of
The specific activity of 64Cu produced by the neutron irradiation of copper is too low to be used in some in vitro tests for metabolic diagnosis. This report describes the use of the Szilard-Chalmers reaction to increase the specific activity to useful levels.
Since its introduction to medicine several years ago, diphenylhydantoin (DPH) has been widely used in the treatment of epilespy, both in adults and children.( 2) The effects of the drug is well correlated with the plasma levels. high levels have adverse effects. ( 3 )
