RESUMO
To determine the extent of involvement of British Columbia's physician community in the operation of the province's only medical school, the authors sent questionnaires to all physicians who had any affiliation with the University of British Columbia (UBC). About 20 percent of the province's physicians were involved in some capacity with the UBC Faculty of Medicine, which accepts about 120 students into the first year annually. Most faculty held "clinical" appointments, meaning that they pursued largely non-academic careers. Full-time academic appointees worked more than 20 percent more hours annually than did their "clinical" counterparts, and average hours for men exceeded those for women. As many as two-thirds of the full-time faculty were also engaged in sufficient clinical practice activity to be classified as full-time practicing physicians by a definition adopted by a provincial Joint Medical Manpower Committee.

Studies were carried out, using transmission electron microscopy, of the cilia of the nephrons of rat and human kidneys. Cilia were observed in the parietal layer of Bowman's capsule, in the proximal tubule, the distal tubule, including the macula densa, and the collecting duct. They had a number of characteristic features, including the presence of a centriole adjacent to the basal body, long, slender cross-striated rootlets, and a typically organized basal body. The shaft of the cilia differed from the typical 9 + 2 pattern of organization. Near the base of the cilia the pattern was 9 + 0. In the middle portion, one or more of the peripheral doublets had been displaced centrally to give an 8 + 1 or a 7 + 2 pattern, while towards the tip the pattern became more irregular and the doublets were reduced to single microtubules. We have hypothesized that these cilia may be vestigial. They may, if motile, have some minor stirring function, or they may play a sensory role, as has been postulated for similarly structured cilia in other sites.
