测定胃粘膜血流量的方法很多,但都各有缺点,如氨基比林清除法仅限于测定全胃或小胃粘膜血流量。在局部胃粘膜血流量测定方法中,放射微球法在统计误差和分辨能力方面有一定的缺陷,而多普勒测速计的测定需要插入胃腔;氢气清除法虽然有较高的定位能力,但也仅限于一定数量预先选定的部位,并且要求组织和电极之间有物理性接触。最近W.J.Angerson等采用放射自显影方法测定局部胃粘膜血流量,可
There are many ways to determine the gastric mucosal blood flow, but each has its own drawbacks. For example, aminopyrine scavenging assay is limited to the determination of whole or small gastric mucosal blood flow. In the local gastric mucosal blood flow measurement method, the radial microsphere method has some defects in the statistical error and resolving power, while the determination of the Doppler tachymeter need to be inserted into the gastric cavity. Although the hydrogen scavenging method has higher positioning ability, But it is limited to a certain number of preselected locations and requires physical contact between the tissue and the electrodes. Recently W.J.Angerson and other methods using autoradiography to determine the local gastric mucosal blood flow can be
