野生与养殖黄鳍鲷消化道中粘液细胞的类型及分布
采用常规石蜡组织切片及AB-PAS的染色方法对野生和养殖黄鳍鲷（Sparus latus）消化道中粘液细胞的类型及分布情况进行了比较观察研究。黄鳍鲷粘液细胞在消化道各部位均有分布，不同部位粘液细胞的类型和分布均有差异。食道中以Ⅰ、Ⅱ型粘液细胞为主；贲门部和胃体部只有Ⅰ、Ⅱ型粘液细胞分布，幽门部只有Ⅰ型粘液细胞；幽门盲囊、肠道及直肠都是Ⅱ型粘液细胞最多。野生与养殖黄鳍鲷粘液细胞的区别在于消化道的相同部位养殖鱼比野生鱼粘液细胞数量更多。根据研究结果推测粘液细胞的类型和分布与鱼的生活环境及食物相关，也可能与消化道中各种菌群的分布有关。...

| Bibliography: | yellowfin black porgy （Sparus latus） digestive tract mucous cells We study the types and distribution of mucous cells in the digestive tract of wild and cultivated yellowfin black porgy （Sparus latus） by using routine paraffin tissue section and AB-PAS staining method. The mucous cells distribute at every section of the alimentary canal of yellowfin black porgy; however, the types and distribution of cells vary at different sections. TypeⅠandⅡ mucous cells are in the majority in esophagus; cardiac stomach and fundic stomach only have TypeⅠand Ⅱ; pyloric stomach only has Type Ⅰ; Type Ⅱ is in the majority in pyloric caeca, intestine and rectum. The difference of wild and cultivated yellowfin black porgy lies in the number of mucous cells which are more in wild fish than in cultivated fish at the same section of digestive tract. It is concluded that the types and distribution of mucous cells in the digestive tract are related with the living condition and food of fish, and probably with the distribution of flora. |
