Objectives: The purpose of this study is to investigate the effect of Melandrii Herba (MH), Akebia Quinata Decaisne (AQ), and Tetrapanax Papyriferus (TP) on milk secretion and aquaporin (AQP) expression in lactating mice.
Methods: For the experiment, the mice were divided into three groups, which were orally administered MH (2,720 mg/kg), TP (400 mg/kg) and AQ (2,800 mg/kg) extracts respectively for 3 weeks from Day 1 after the birth, compared with the control group (C group), which was administered distilled water. A group consisted of six infantile mice per postpartum mouse. For comparison with the C group, non-pregnant SKH-1 mice were used as the virgin group.
Results: 1. When it comes to the immunohistochemical staining for prolactin receptors in the mammary glands, the AQ and MH groups showed a strong immune response to the secretory epithelial cells constituting the mammary alveoli, while the TP group represented a weaker immune response. 2. In the immunohistochemical staining for AQP in the mammary glands, AQP1 showed a strong immune response in the walls of capillaries and venules around the mammary alveoli, and AQP3 in the epithelial cells constituting the mammary alveoli, and AQP5 in some tissues between the mammary alveoli. AQP1 was expressed in the order of TP group>AQ group=C group>MH group, and AQP3 was MH group and AQ group>TP group=C group, and AQP5 was MH group>C group>AQ group and TP group. 3. In the Western blot, AQP1 was expressed in the order of TP group>AQ group>C group>MH group, and AQP3 was MH group>AQ group>C group>TP roup, and AQP5 was MH group>TP Group>C group>AQ group. All of AQP1, 3, 5 expression were significantly higher in the C group than in the Virgin group.
Conclusions: The administration of Akebia Quinata Decaisne, Tetrapanax Papyriferus and Melandrii Herba have the effect of improving prolactin levels in postpartum mice and increasing the expression of prolactin receptor and AQPs in the mammary glands, suggesting that lactation might be enhanced by the development of the mammary glands.
