In situ observations of spontaneous contractions of the peripheral lymphatic vessels in the rat mesentery: effects of temperature.
By means of an intracellular glass microelectrode, action potential changes were successfully recorded in situ from the endothelial cells of rat mesenteric lymphatics over the temperature range of 27-40 degrees C. The frequency of action potential and the lymphatic contraction rate correlated well with temperature.
