THE EXPRESSION AND SIGNIFICANCE OF LEPTIN AND LEPTIN RECEPTOR IN RAT SUBMANDIBULAR GLAND / 解剖学报

Objective To study the location and significance of leptin and leptin receptor in rat submanibular gland. Methods Submandibular gland from SD rats were observed by hematoxylin-eosin, leptin and leptin receptor immunohistochemical staining. Result The granular convoluted tube and striated duct were leptin and leptin receptor positive. The density of positive cells in granular convoluted tube were much high than those of in striated duct. The acini were negative.Conclusion leptin and leptin receptor were widly expressed in granular convoluted tube and striated duct. These results might indicate that submandibular gland participated in adjusting the balance of energy.;
