淋巴管壁、血管壁氧耗量的测量

Measuring Method of Oxygen Consumption of Lymphatics and Blood Vessels

应用OBN—Ⅲ型生物组织氧耗仪,测量了大鼠新鲜淋巴管壁、腔静脉管壁、腹主动脉管壁1min的氧耗量。结果征明:15只大鼠腹主动脉壁内膜面氧耗量明显高于淋巴管壁和腔静脉管壁内膜面氧耗量(P<0.001);淋巴管壁氧耗量高于腔静脉管壁(P<0.001);而腔静脉管壁氧耗量最低。结果说明腹主动脉管壁氧耗量高与它在执行功能过程中内皮细胞与平滑肌细胞耗能大有关,而淋巴管壁耗氧量高于腔静脉管壁是与淋巴管保证淋巴液回流,及淋巴结产生免疫球蛋白等物质与淋巴管内皮细胞直接接触需要消耗能量有关。

The oxygen consumption per minute of the freshly prepared lymphatics (chylocystis & tborathic ducts), vena cava and abdominal aorta from rats was measured with OBM-Ⅲ equipment for measuring of biological tissue oxygen consumption. The results demonstrated that the oxygen consumption of the inner endothelial surface of the abdominal aorta from 15 rats was much higher than that of the lymphatics and the vena cava (P<0.001). The oxygen consumption of lymphatics was higher than the vena cava (P<0.001), but lower than the abdominal aorta. The oxygen consumption of the vena cava was the lowest. Theseresults indicated that the high oxygen consumption of the aorta was due to the high consumption of the energy of the endothelial and smooth muscle cells during their functional activity. While the higher oxygen consumption of the lympatics was assotiated with energy consumption for the returning of the lymph flow, and for the contact of immunoglobulins produced in the lymphatic glands with the endothelial cells of the lymphaties.
