摘要
为探寻不同发育阶段及不同性别间血吸虫生物学反应差异性的结构基础,本研究对不同发育阶段及雌、雄虫体间的超微结构进行了比较观察。经比较发现,血吸虫的体被和肠上皮两个直接跟外界接触的界面均在童虫阶段薄而致密,而成虫阶段这两个界面都更厚而稀疏。雌虫体被比同一发育阶段的雄虫体被致密,基膜比雄虫厚。了解血吸虫不同发育阶段及雌雄虫体间超微结构的差异性,有助于解释其生物学反应的差异性。
To explore the structural basis that might cause diverse responses to biological treatments, the ultrastructures of worms at different developmental stages and genders of Schistosoma japonicum were compared in the present study. The teguments and intestinal epitheliums, through which worms contacted with the outside world directly, were thinner and more compact in schistosomulums than in adults. The teguments of female worms were more compact than in male worms at the same stage while the basal lamina of female worms were thicker than male worms at the same stage. The differences on ultrastructures may help explain different biological responses at different developmental stages or different genders of Schistosoma japonicum.
