Fig. (1) Salivary secretion induced by NE in non-irradiated and 30 (A), 90 (B), 180 (C) and 365 (D) days post irradiated rats. Values represent means + SEM of 6-8 animals per group. Maximal secretory response obtained to NE in irradiated (E) and non-irradiated (F) rats. Values represent means ± SEM of 6-8 animals per group.*p<0.05, **p<0.01 and ***p<0.001 versus respective control. ###p<0.001 versus 2 h, 30 and 90 days post irradiation.
