title: [A stereological study of the remaining parotid gland of rat after duct-preserved partial parotidectomy].
abstract: The remaining parotid glands of rats after duct-preserved partial parotidectomy were sectioned and examined randomly by stereological methods which determine acinararea and proportional volumes (PV) of the component tissues. The volume of the remaining glands were measured at the same time. Results showed that: 1. there were no difference of the above quota 1-3 days after the operation (P > 0.05); 2. 1-2 weeks after the operation, the gland volume decreased (P < 0.05) with the PV of acini decreasing (P < 0.05); 3. 4-7 weeks after the operation, the acinar area increased (P < 0.05), the PV of acini and gland volume regained (P > 0.05). All the results indicate, with the duct preserved, the remaining parotid glands after partial parotidectomy do have the regenerating ability and significant function.
