摘要

为了研究重离子射线照射后家蚕造血器官的修复再生作用，用碳离子射线局部照射家蚕接近孵化时紧贴翅原基内侧的胚胎造血器官，局部细微手术损伤造血器官，观察了对幼虫造血功能的影响，了解了造血器官的修复程度。100Gy以上剂量照射，家蚕出现变态困难，幼虫和蛹的生存率下降，眠中、化蛹或羽化时期出现死亡个体等缺血生理障碍，其影响程度随射线剂量增加而加重。200Gy照射组5龄存活幼虫血细胞含量下降，但其中部分个体的血细胞含量接近对照未照射处理，其体内出现了再生的造血器官。家蚕幼虫有很强的修复再生造血器官功能。

Abstract

Eggs of silkworm,Bombyx mori, were irradiated by ,12,C,5+, ions, at the embryonic wings, where the hemopoietic organs attached. Changes in the development of the silkworm larvae and pupae, especially in the repair and regeneration of the hemopoietic organs represented by their morphological and functional characteristics, were observed. The results showed that the silkworm larvae and pupae developed from the irradiated eggs grew with the physiological obstruction due to exsanguinations, such as difficulty in their metamorphosis and their marked lower survival rates. After 100Gy irradiation, some of the larvae and pupae died during the periods of larval molting stages, pupation stage and eclosion stage. With increased doses, the deficiencies in the silkworm development became more significant. After 200Gy irradiation, the average hemocyte density for the 5th larvae decreased markedly, but the hemocyte density for some individuals were comparable to the control, and regenerated hemopoietic organs was found in these larvae. The results suggested that the silkworm larvae might be capable of self-repair and self-regeneration of the hemopoietic organs after the heave ion irradiation.
