| Abstract: | Separated lymphocytes from untreated and selenium-supplemented lambs were tested in culture against phytolectins (phytohaemagglutinin and pokeweed mitogen). Levels of response varied considerably among individuals, and this tended to mask the effects of selenium. However, cells from both groups were more active in the presence of serum from supplemented animals, and a similar stimulatory effect was achieved by adding sodium selenite in vitro. Thus selenium could exert a direct influence on the performance of immunocompetent cells. |
