[Significance of fluorescence spectra for the evaluation of lens opacities].
The fluorescence spectra of nucleus and cortex material from human lenses obtained as a result of extracapsular cataract extraction were observed. With advancing cataract formation the fluorescence spectra changed in a very characteristic way. The changes in ascorbic acid were compared with those caused by cataract development. Clinical application of corresponding measuring instruments would appear to make sense.

Evaluation of a direct spectrophotometric method for the rapid determination of ascorbate and dehydroascorbate in blood using ascorbate oxidase.
The application of a technique for the direct spectrophotometric determination of ascorbate and dehydroascorbate in blood samples is described. The reliability of the test system and various disturbing factors are assessed. It is concluded that the technique possesses a high specificity and that interferences by various biochemicals and metabolic intermediates are low. The lowest ascorbate concentration detectable in plasma by this assay is estimated to be about 1 mumol/l.
