In the paper an attempt to define pathogenesis of changes in somatic growth of juvenile individuals of the popular freshwater snail Lymnaea stagnalis experimentally infected with parthenites of the trematode Opisthioglyphe ranae was undertaken. Significant enlargement of relative wet weight of examined accessory sex organs (albumen gland, oothecal gland, prostate, male copulatory organ) observed in infected snails permits to explain increase of their somatic growth basing on the hypothesis of disturbances in energetistic budget of the host-as a consequence of reduction by the parasite activity of the snail's reproductive system. Pathogenesis of this phenomenon has probably a complicated character, including also effect of parthenites on activity of the neurosecretory cells that control somatic growth in examined species of the snail. An argument for this standpoint is, observed in infected snails, increase of amount of neurosecretory material and RNA in cytoplasm of these cells (the light green cells of cerebral ganglia), as well as amount of the loose fraction of chromatine in their nuclei.
本文尝试确定实验感染蛙后睾吸虫单性生殖体的常见淡水蜗牛——静水椎实螺幼体体细胞生长变化的发病机制。在受感染的蜗牛中观察到，所检查的附属生殖器官（蛋白腺、卵囊腺、前列腺、雄性交配器官）相对湿重显著增大，这使得我们能够基于宿主能量预算紊乱的假设来解释其体细胞生长的增加，这种紊乱是由于寄生虫活动导致蜗牛生殖系统功能下降所致。这一现象的发病机制可能具有复杂的特征，其中还包括单性生殖体对控制所研究蜗牛种类体细胞生长的神经分泌细胞活性的影响。支持这一观点的一个论据是，在受感染的蜗牛中观察到，这些细胞（脑神经节的浅绿色细胞）细胞质中神经分泌物质和RNA的量增加，以及其细胞核中染色质松散部分的量增加。
