| 摘 要： | 目的研究牛蛙(Rana catesbeinana)消化道黏膜碱性磷酸酶(ALP)、酸性磷酸酶(ACP)、ATP酶、酯酶和脂酶的分布。方法在消化道的8个部位取材,采用冰冻切片技术和酶的组织化学方法。结果 ALP主要分布于十二指肠、空肠和回肠,胃中酶反应呈弱阳性。ACP主要分布于胃中,食道和肠道酶反应呈弱阳性。ATP酶在消化道各部位均有较多分布,十二指肠、空肠和回肠显著较多,胃各部位其次。酯酶和脂酶均主要分布于肠道,胃各部位其次。结论牛蛙消化道黏膜酶的分布同其它动物有相似之处,也有其自身特点。十二指肠、空肠和回肠是牛蛙的主要消化吸收部位。

| Abstract: | Objective To investigate the distribution of alkaline phosphatase(ALP),acid phosphatase(ACP),ATPase,esterase and lipase in the gastrointestinal mucosa of Rana catesbeinana.Methods Tissue samples were taken from 8 parts of the digestive tract.Frozen sections and enzymatic histochemical techniques were used.Results ALP was mainly distributed in duodenum,jejunum and ileum,and the enzymatic reaction of ALP in the stomach was weakly positive.ACP was mainly distributed in the stomach,and the enzymatic reaction of... |
