综合以4～6℃或结冰刚融的多聚甲醛-戊二醛前固定液固定标本的观察结果,作者等提出日本血吸虫成虫体壁概略的设想构型。皮层实质中存在一些具单位膜的弯曲小管,其外端与表质膜或表质膜内凹相连,其内端与基质膜外褶相通。在常态下此类小管闭锁不通,或仅部分小管开放,而形成上述所谓表质膜内凹,或小管内分段膨大。当接触外界环境的变异因素,皮层在结构上迅速作出反应性改变。小管部分段
Based on the observation results of paraformaldehyde-glutaraldehyde pre-fixative specimens frozen at 4 ~ 6 ℃ or icesolid, the authors proposed a schematic conception of the body wall of adult Schistosoma japonicum. There are a number of cortical membrane with a small unit of the curved tube, the outer end of the surface membrane or epidermal membrane concave connected to its inner end of the matrix membrane pleated. Under normal circumstances such tubular barrier is blocked, or only part of the small tube open, and the formation of the so-called surface membrane concave, or small tube within the segment expansion. When exposed to changes in the external environment factors, the cortex in the structure to make rapid changes in response. Tubular section
