Gastric mucosal microcirculation measured by laser Doppler velocimetry in patients with gastric ulcer.


In order to evaluate the role of gastric mucosal blood flow in patients with gastric ulcer, we applied laser Doppler velocimetry to the human gastric mucosa to study the regional microcirculatory mechanism. We measured 5 spots each in 34 control stomachs, and in 47 patients with gastric ulcer at the angle and antrum of the stomach, 2 additional spots around… (More)
