ALA maintains neurotrophic factor levels in SGs. Sprague–Dawley rats were subjected to 18 Gy irradiation in the head and neck region. SGs and serum were collected at each time points after irradiation and subjected to ELISA to measure BDNF (left in A and B) and neurturin (right in A and B) levels. N = 12–16 SGs/group. Values are represented as the mean ± SEM. * p < 0.05.
