Molecular stimulants induce changes in salivary glands. (a) Morphology of H&E-stained salivary glands from Balb/c mice. (b) TUNEL assay (lower panel) showing apoptotic changes in green or yellow in response to different triggers. Nonapoptotic cells were counterstained red with propidium iodide. (c) The graph shows the percentage of apoptotic cells ( value calculated by ANOVA).
