[Melatonin reverses oxidative damage in the submandibular gland of rats treated with Cyclophosphamide].

Objetive: Cyclophosphamide (Cf) produces oxidative damage in rat submandibular gland (GSM). In the present work we evaluated the antioxidant protective effect of melatonin (MLT) in GSM of rats treated with Cf.

Methods: 40 adult male Wistar rats were divided into 5 groups (G): G1: control; G2: Control+Ethanol: treated with 1% ethanol for 10 consecutive days.

Multifocal canalicular adenoma of the minor labial salivary glands.
