Аннотация
Исследована ингибирующая способность по отношению к протеазам экстрактов плероцеркоидов из печени окуня (Perca fluviatilis Linnaeus), а также экскреторно-секреторных продуктов и экстрактов незрелых и зрелых цестод Triaenophorus nodulosus (Pallas, 1781), из кишечника щуки (Esox lucius Linnaeus). Установлено, что ингибирующей способностью по отношению к протеазам в различной степени обладают экскреторно-секреторные продукты и экстракты как незрелых, так и зрелых цестод T. nodulosus. Достоверное снижение активности отмечено при действии исследуемых образцов на активность коммерческого трипсина. Большей ингибирующей способностью по сравнению с экскреторно-секреторными продуктами обладают экстракты червей. При этом экстракт незрелых червей ингибирует активность протеаз сильнее, чем таковой зрелых. В большей степени ингибирующая способность связана с экстрактом червей, лишенных щеточной каймы, чем с фракцией щеточной каймы тегумента.
