作者曾于1959年研究一例急性日本血吸虫病尸检标本,从中推断虫卵已通过肺循环而进入体循环,惜未作进一步研究。现另获病例深究发现:此病原是血吸虫成虫在肺动脉系血管内异位寄生,就地产卵,导致许多大小不一的嗜酸性脓肿;雌雄合抱的成虫多系分布在病变区外的血管内,也有少数是在病变区内,而以病变最轻的肺尖部分布最多;所见均为变形缩小了的死虫骸,有的象血栓,偶可看出虫样轮廓及所附虫卵,有的雄虫仅留下体壁,其背侧紧贴着扩张成囊状的血管壁,雌虫残余部分浓缩而怀着一个或几个卵,被上述空虚的雄虫抱住;其卵颇新鲜,往往引起了邻近纤维组织向心增殖。总的形象酷似一个有虫卵突入其中的肺泡,只不过其壁着苏木紫色较深而已。此外,还发现肺中的所谓嗜酸性脓肿是由一群肺泡内型血吸虫性肉芽肿组成,每个这样的肉芽肿旁伴有一道镰状空隙。而单个的血吸虫性肉芽肿旁也有这样一个镰状空隙。这是由肺泡壁向肺泡腔凸出的肉芽肿,其旁的镰状空隙正是该肺泡的残余泡腔。实质上是一种特殊形式的肺泡膨胀不全。
The author studied a case of acute schistosomiasis japonica autopsy specimens in 1959, from which it was concluded that the eggs had passed through the pulmonary circulation and entered the systemic circulation without further study. Now another case study found that: the pathogen is schistosomiasis in the pulmonary artery blood vessels ectopic parasitics, spawning in situ, resulting in many different sizes of eosinophilic abscess; male and female adults more than the line distribution in the diseased area outside the blood vessels, There are also a few in the lesion, and the lightest lesion tip of the most part of the distribution; see deformation are reduced dead worm bones, and some like thrombus, even to see the worm-like contour and the attached eggs, Some males only leave the body wall with their dorsal side close to the wall of the blood vessel that dilates into a sac, and the remnants of the females are concentrated with one or a few eggs and surrounded by the emptiness of the male; the egg is fresh , Often caused the centripetal proliferation of adjacent fibrous tissue. The overall image resembles an alveolus into which the eggs enter, except that its wall is darker and darker purple. In addition, the so-called eosinophilic abscess in the lung was found to consist of a group of alveolar endogenous schistosomal granulomas, accompanied by a sickle-shaped space alongside each such granuloma. And a single schistosomiasis granuloma also has such a sickle-like space. This is a granuloma that protrudes from the alveolar wall to the alveolar space, and the sickle-shaped space next to it is the remnant of the alveoli. Is essentially a special form of alveolar dilation incomplete.
