title: [Advances in the research of the peritoneal lymphatic stomata in human].
abstract: Peritoneal lymphatic stomata are small openings of the subperitoneal lymphatic vessels on the free surface of the mesothelium. The peritoneal cavity is connected with lymphatic system via these small openings which are considered to be the main passage-way that can absorb matter from the peritoneal cavity. The lymphatic stomata are claimed to be involved in many clinic procedures, such as ascites elimination; ultrafiltration failure on the continuous ambulatory peritoneal dialysis; metastasis of tumor cells from the peritoneal cavity, and so on. It was reported that the cellular factor-NO(i.e. endothelium-derived relaxing factor, EDRF) can enhance the patency of the stomata and lymphatic absorption of the stomata by stimulating guanylate way, then increasing the concentration of the cGMP, decreasing the concentration of the [Ca2+] and as a result diastole the lymphatic stomata. Some traditional Chinese medicines, which can enhance absorption of ascites, have a regulative function on the stomata by enhancing the NO concentration.
