大鲵血细胞发生的初步研究

A primary study on megalobutrachus davidianus' hemocytopoiesis

目的 :确定大鲵成体后血细胞发生的模式及其造血器官。方法 :骨髓及脾组织涂片用Giemsa(姬姆萨 )染料染色 ,光镜镜检并记录结果。结果 :在骨髓及脾组织涂片中均发现存在有造血干细胞和血细胞发生相应阶段的细胞。结论 :大鲵成体后 ,血细胞发生的模式与高等脊椎动物的相类似 ,红骨髓是其成体后活跃的造血器官 ,脾的造血功能虽不及骨髓活跃 ,但其仍是大鲵终生的造血器官。

Objective: To determine the hemocytopoiesis pattern and hemopoietic organ of the adult megalobutrachus davidianus. Method: The medulla ossium smear and spleen smear were stained with Giemsa dye and observed with the optical microscope. Result: The hemopoietic stem cell was discovered in the medulla ossium smear and spleen smear, and the cells in different phase of hemopoiesis were discovered also. Conclusion: The hemopoiesis pattern of the adult megalobutrachus davidianus is similar to that of other vertebrates, and red medulla ossium is its active blood producer, the hemopoietic function if its spleen is inferior to that of its red medulla ossium, but its spleen is capable of producing blood cells in its all life.
