Abstract:
:The selective toxicity of silica dust for macrophages has been used to assess the role of these cells in experimental allergic neuritis (EAN). Inbred Lewis rats were inoculated with bovine dorsal roots in Freund's complete adjuvant (day 0). In two experiments, animals received 200 mg of silica dust in 1 cm3 of saline intraperitoneally (IP) at days 8 and 16. In another two experiments, animals received IP silica at days 3, 7, and 11. Control animals received 1 cm3 saline IP at corresponding times. Regular clinical assessment showed that in animals treated on days 8 and 16 there was a significant delay in the time taken to reach their maximum degree of illness. This delay was not seen in the animals treated on days 3, 7, and 11. Neither of the injection regimes reduced the final maximum severity of the disease. In three experiments recovery of the treated and control animals occurred concurrently, hence the duration of the disease was reduced in the animals treated at days 8 and 16. However, in one group of animals given silica at days 3, 7 and 11, there was a delay in the time taken to recover from the most severe phase of the disease but thereafter the treated animals improved more quickly to reach their best grade at the same time as the controls. If the silica blockade of macrophages is to be effective in delaying the onset of EAN, the timing of injections is critical.
