Science. 1966 Nov 18;154(3751):903-5. doi: 10.1126/science.154.3751.903.

egatively stained cytoplasmic microtubules of lung-fluke sperm show a helical structure that is not found in peripheral doublet tubules of axial units. In transverse sections, the wall of such microtubules appears to comprise about eight subunits.

肺吸虫精子经负染的细胞质微管呈现出一种螺旋结构，这种结构在轴单位的外周双联微管中未发现。在横切面上，这种微管的壁似乎由大约八个亚基组成。
