[Electronic data processing-assisted text processing at the clinic and in general practice].

Word processing is currently the most frequent application for personal computers, and a wide variety of standard software is available. The capabilities of modern word-processing software includes the convenient typing and correction of all routine correspondence, as well as the professional layout of scientific manuscripts. The decision to purchase a certain word-processing programm should be made according to local needs and prerequisities. Three to six months may be necessary to fully adapt the organization of a clinic or private practice to the new technology.

[Microcomputer systems in urology: hardware--mole's hole or useful equipment?].

The basic concepts and elements of micro- and minicomputer hardware components frequently used in urology are described. For advanced users, the details and trends are discussed in more detail. The interdependence of hardware and operating systems is emphasized. In addition, a method for the evaluation of personal computer performance is presented. Finally, proposals are made concerning purchasing procedures and selection criteria.

Temperature dependence of the disintegration times of compressed tablets containing hydroxypropylcellulose as binder.

The dependence of the disintegration times of placebo and active tablets containing hydroxypropylcellulose (HPC), as binder on the temperature of the test medium in the region of 37 degrees is reported. The degree of temperature dependence varied with the HPC lot and concentration in the formulation of certain drugs, such as caffeine. The extent of the temperature dependence could be diminished by reducing the HPC concentration in the formulations. Corresponding trends were observed in drug release behaviour from some of these formulations. The effects observed were interpreted in terms of the thermodynamic behaviour of HPC systems and a specific drug-HPC interaction.

Cumulation and elimination of horse-anti-dog lymphocyte and normal horse gammaglobulin in dogs.

Two groups of dogs received daily intravenous doses of 20 mg/kg 131-I-labelled horse-anti-dog lymphocyte globulin or normal horse gammaglobulin respectively over a period of 11 days. Horse-anti-dog lymphocyte globulin showed a significantly higher eleimination rate than normal horse gammaglobulin. In contrary to the continuous increase in serum radioactivity during normal horse gammaglobulin treatment, there was a plateau after the 5th day in the horse-anti-dog lymphocyte globulin group. The xenogeneic protein concentration, measured with the single radial immunodiffusion technique, at the end of treatment was 165 +/- 8 mg/1 in the horse-anti-dog lymphocyte globulin, compared to 498 +/- 15 mg/1 in the normal horse gammaglobulin group. After treatment horse-anti-dog-lymphocyte globulin treated animals showed a significantly higher increase in active hemagglutination titer against horse erythrocytes with an average of 2(-8).
