花背蟾蜍胃肠的血供研究

用血管铸型法对15只花背蟾蜍（Bufo raddei)胃肠的动脉和静脉进行了解剖学观察，结果显示：花背蟾蜍胃肠的动脉均来自腹腔肠系膜动脉，胃的营养由胃左动脉和胃右动脉供应；肠由肠系膜前动脉和肠系膜后动脉共同营养，胃的静脉包插胃左静脉和胃右静脉，分别收集胃左侧面和胃右侧面胃壁的静脉血，经肝门静脉回流；肠的静脉有肠系膜前静脉和肠系膜后静脉，前者收集十二指肠和回肠前段肠壁的静脉血，后者收集回肠后段和直肠壁的静脉血，最后经肝门静回流，与此同时，将花背蟾蜍胃肠的血供与其它动物进行了比较。

A study of the blood supply on gastrica and intestine of Bufo raddei

Arteries and veins of the gastrica and intestine o n 15 Bufo raddei were studied by arterial casting and anatomal methods.The r esults showed that the arteries of gastrica and intestine of Bufo raddei com e from the coeliacomesenteric artery.The gastric is supplied by the artery gastr ica sinistra and the artery gastrica dextra.The intestine is supplied by the ar teries mestenterica anterior and posterior.The gastric veins includes veins gast rica sintrica and dextra whi ch accumulates the gastric vein blood of left and right walls respectively and d raines into the vein portalis hepatica.The veins of intestine includes the veins mestenterica anterior and posterior which also draines into the vein portalis h epatica.The former mainly accumulates the vein blood of the intestine duodenum a nd the anterior segment of intestine ileum.The latter mainly accumulates the vei n blood of rectum and the posterior segment of the intestine ileum.In addition,t he blood supply of stomach and intestine on Bufo raddei was compared with th ose other of animals.
