Fluorescein-labeled antigen-antibody complexes could be made visible by scanning electron microscopy using an intensifying device. This new method of immunocathodoluminescence was demonstrated on cryostat sections of rat kidneys containing glomerular fibrin as the result of endotoxin infusion. The resulting photographs correspond with those obtained by immunofluorescent microscopy. The advantage of this technique is, however, the larger depth of focus. By using thinner cyostat sections it is expected that the higher resolution of scanning microscopy will provide even better details in three dimensions.

In order to distinguish between different types of people endangered by alcohol, five different indicators were used to classify the degree of alcohol affinity: KFA/Feuerlein, German version of part of the Manson Evaluation, alcohol-in-blood concentration, and frequency and amount of drinking. The degree of alcohol affinity potential is quite different depending on each indicator. All indicators together discriminate between nine independent types (each for men/women) of alcohol-endangered people. Further-more, five independent drinking motivations could be factor analyzed. The diversity in this field was completed by sixteen different therapies used by physicians for alcoholism treatment.
