Studies were conducted of the content of ferments with which metacercariae of trematodes of the genus Diplostomum affect the tissues of the host's crystalline lens. The following ferments were found in exudates of metacercariae: pepsin, cathepsin, hyaluronidase and lipase. Their activity depends to a great extent on temperature. Considerable changes in the biochemical content of crystalline lens infected with the parasites were found. The character and force of pathogenic effect of diplostomatids on fishes depend on the factors associated with activation and inhibition of ferments of metacercariae, temperature and the presence of ions-inhibitors in particular.
对复口吸虫属吸虫尾蚴影响宿主晶状体组织的酶类成分进行了研究。在尾蚴的渗出物中发现了以下几种酶：胃蛋白酶、组织蛋白酶、透明质酸酶和脂肪酶。它们的活性在很大程度上取决于温度。发现感染寄生虫的晶状体生化成分发生了显著变化。复口吸虫对鱼类致病作用的性质和强度取决于与尾蚴酶的激活和抑制、温度以及特别是离子抑制剂的存在相关的因素。
