    Abstract:
    In this study, the effect of increasing doses of aspirin on the neurite outgrowth of Dorsal Root Ganglia (DRG) was investigated. DRG were cultured in complete medium (DMEM + 10% FCS +100 ng/ml NGF + collagen Type1 in substratum in 96 multiwell plate) in the presence of concentration of 1.25, 2.5, 5 and 10 mM aspirin. The neurite outgrowth of DRG was followed in comparison with controls that lack aspirin. 10 mM aspirin treated DRG showed delayed neurite outgrowth and after 7 days it reached the same DRG neurite outgrowth control wells after 18 hrs. This growth has delayed approximately one week and showed no further development and in such stage the cells became apoptos. However at concentrations of 1.25, 2.5, 5 mM of aspirin, outgrowth was observed after 18-24 hrs. Although the rate of growth was lower than control, it was not significant. In the other experiment, when DRG cultured for one week in complete medium then treated with aspirin, at 10 mM, DRG neurite outgrowth was stopped, while it was continued in the control. It seem that the aspirin affected DRG became apoptosis.
