Research Abstract |
Fluid secretion in response to muscarinic agonists was analyzed using a mouse ex vivo submandibular perfusion technique. Lowering the temperature from the body temperature induced less salivation. Also, increasing the osmolarity in perfusion solution caused less fluid secretion. Pharmacological inhibition on channels, receptors and transporters crucial for fluid secretion also inhibited fluid secretion. Ion concentrations in secreted ex vivo saliva turned out their ion compositions were different among hyposalivaiton models. The results suggest that ion concentration analysis might work for identifying the target which causes hyposalivation.
