作者对日本血吸虫中间宿主湖北钉螺的血淋巴细胞的形态及体外行为进行了观察。钉螺血淋巴液中常见的细胞为伸展性阿米巴细胞。来自安徽及云南的钉螺的此种细胞大小分别为８．４２±０．７３×７．４６±０．５２μｍ及７．６３±０．６５×６．８５±０．５４μｍ。细胞核呈圆形，胞浆内有嗜酸性颗粒，细胞接触玻片后，伸出伪足。两地螺的阿米巴细胞均具有体外吞噬羊红细胞的能力。本文介绍了采集湖北钉螺血淋巴液的方法，并讨论了该方法在研究寄生虫－宿主关系及在日本血吸虫病流行病学研究等方面的意义。
The authors observed the morphological and in vitro behavior of blood lymphocytes from Schistosoma japonicum, an intermediate host of Schistosoma japonicum. The common cells in the blood of snail lymph nodes are amoeblastic cells. Such cells from Oncomelania of Anhui and Yunnan were 8.42 ± 0.73 × 7.46 ± 0.52μm and 7.63 ± 0.65 × 6.85 ± 0.54μm, respectively. The nucleus is round, there are eosinophilic granules in the cytoplasm, cell contact slide, the extended pseudo-foot. Both Leptospira amoebocytes have the ability to ingest sheep red blood cells in vitro. This article introduced the method of collecting snail hemolymph of Hubei and discussed the significance of the method in studying the parasite-host relationship and epidemiology of schistosomiasis japonica.
