The hypothesis is that the parotid glands are a target for LFN\u2010induced lesions.<\/jats:p><jats:p><jats:bold>Materials and methods:\u2002<\/jats:bold> Ten rats were exposed to LFN for 2184 consecutive hours while 10 rats were kept under similar conditions but in silence for control purposes. The parotid glands were surgically removed. One gland was sectioned and stained with hematoxylin\u2013eosin and periodic acid Schiff for light microscopy observation. The other was used for functional amylase secretion measurements, basal and nerve\u2010mediated [with electrical field stimulation (EFS)] and secretagogue\u2010evoked secretion [acetylcholine (ACh) 10<jats:sup>\u2010\u20105<\/jats:sup>\u2003<jats:sc>m<\/jats:sc>] with established fluorimetric techniques.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> All the rats exposed to LFN showed marked morphological lesions including vacuolar degeneration, hyalinization, cell death and blood vessels wall focal thickening. No morphological changes were detected in the control group.
