Mechanism involved in Danshen-induced fluid secretion in salivary glands Basic Study
2015
AIM: Danshen’s capability to induce salivary fluid secretion and its mechanisms were studied to determine if it could improve xerostomia. METHODS: Submandibular glands were isolated from male Wistar rats under systemic anesthesia with pentobarbital sodium. The artery was cannulated and vascularly perfused at a constant rate. The excretory duct was also cannulated and the secreted saliva was weighed in a cup on an electronic balance. The weight of the accumulated saliva was measured every 3 s and the salivary flow rate was calculated. In addition, the arterio-venous difference in the partial oxygen pressure was measured as an indicator of oxygen consumption. In order to assess the mechanism involved in Dansheninduced fluid secretion, either ouabain (an inhibitor of Na
