Abstract
An experimental model of blockage of the mesenteric lymphatic flow (MLF) in rats was designed, and morphologic changes of mesenteric lymphatic vessels (MLV) and lymph nodes were investigated by mesenteric lymphangiography and histopathologic examination. Body weight in rats with blockage of MLF did not increase normally. Mesenteric lymphangiography revealed dilation of the MLV, reverse flow into the peripheral MLV, and leakage of contrast medium, resulting in chylous ascites. Remarkable dilation of the lymphatic sinuses and dilated and increased rough endoplasmic reticulum in lymphocytes in the mesenteric lymph nodes due to lymph stagnation were observed by light and electron microscopic examination, respectively.
