A corrosion casting technique was used to study differences in the microvascular architecture of the pars cardiaca, the fundus ventriculi, the corpus ventriculi and the pars pylorica of the canine gastric mucosa. This technique revealed an unusual arrangement of the microvascular architecture in the nonglandular region surrounding the esophageal opening. Capillaries run tortuously along the mucosal surface parallel to the long axis of the esophagus, and some capillaries form a polygonal network that extends around the seromucous glands. In contrast, the mucosal capillaries of the glandular regions of the stomach are arranged in a symmetric pattern associated with the gastric glands. There are also differences in the mucosal microvessels of the cardiac and fundic areas compared to the corpus and the antrum. In the cardiac and fundic regions, a sparse microvascular pattern was observed and fewer capillaries drained into a single venule. However, the vessels surrounding the gastric glands in the corpus and antral areas drained into venules perpendicular to the hexagonal arrangement of the capillaries.
采用腐蚀铸型技术研究犬胃黏膜贲门部、胃底部、胃体部和幽门部微血管结构的差异。该技术揭示了食管开口周围非腺区微血管结构的异常排列。毛细血管沿黏膜表面呈曲折状走行，与食管长轴平行，一些毛细血管形成多边形网络，围绕浆液腺延伸。相比之下，胃腺区的黏膜毛细血管呈与胃腺相关的对称模式排列。与胃体部和胃窦部相比，贲门部和胃底部的黏膜微血管也存在差异。在贲门部和胃底部，观察到微血管分布稀疏，较少的毛细血管汇入单一小静脉。然而，胃体部和胃窦部胃腺周围的血管汇入与毛细血管六边形排列垂直的小静脉。
