The propagation of FMD virus on BHK 21 clone 13 suspension cells was based on the Lindholm B medium during the production period August 1975 to June 1976. The medium was used in connection with a production cycle including decreasing amounts of serum in the cell growth medium and inoculation of the cells while they were still in growth. This method of virus production, compared with the traditional method, is cheaper due to the lowered medium cost. The improved utilization of the fermenter capacity and the decreased consumption of serum have practical as well as economic aspects. The results obtained during the period indicate that virus production by this method is reliable and at least on the same level as by traditional methods.

Like logopedics, augmentative and alternative communication (AAC) has a short history and a long past. In the 1950s and 60s the field of AAC emerged as a response to the need of individuals who, despite years of 'traditional speech therapy', had not developed adequate oral communication skills, and for whom compensatory rather than remedial approaches were thus deemed advisable. Various trends like the shift from form to function in language development research, dissemination of sign language, use of non-speech graphic symbols, advances in computer technology, and international collaboration have all contributed to AAC's present-day status as a multidisciplinary enterprise involving speech-language therapists and an array of other professions. Clinical experience, for lack of comprehensive empirical studies, seems to indicate that AAC is warranted for congenital as well as acquired communication disorders.
