A standardized system for patient documentation.

Properly used, patient photography is of value for health-care service, education and research. Many stages in an illness or disease can be better described with photographs than with words. Some of the reasons why photographs are not routinely used in patient records have been discussed by Cederblom and Roos (1980): pictures taken of a particular patient on different occasions are seldom comparable; the time between referring a patient to the photographer and having the picture available to the doctor is too long in many hospitals; the photographic archives are mostly incomplete, difficult to use and therefore of little value. To reduce these problems a new system for patient documentation, the 'PADOC' system, has been developed and has been used successfully at Sahlgren's Hospital, Gothenburg, Sweden, since 1979.

[Isolation of cytostatically active proteins from seeds of Ricinus communis, Abrus praecatorius and Canavalia ensiformis (author's transl)].

The extraction and isolation of, as yet, uninvestigated antitumor active protein mixtures from the seeds of Abrus praecatorius, Canavalia ensiformis and especially Ricinus communis is reported. By means of membrane ultrafiltration of crude ricin a low-molecular weight protein mixture, Ro 413, could be obtained, which showed, in comparison to ricin-toxin, a reduced toxicity but with the same cytostatic action. An almost complete separation of Ro 413 into the individual components was achieved using preparative disc electrophoresis. Using the same procedures it was also possible to isolate a low-molecular weight protein mixture from the crude extract of Abrus praecatorius beans and to concentrate their various individual components. The characterization, toxicity and cytostatic action of these proteinaceous plant materials are reported.
