[An analysis of the results of histological and histochemical research on the integumental tissues and the digestive system of nematodes of the suborder Strongylata after the use of anthelmintics].

The analysis of the action of various anthelmintics on the integuments and digestive system of Strongylate nematodes indicated that all the used agents caused varying structural disorders. The swelling of the cuticle and its detachment from the subcuticle occurred with the overwhelming majority of the anthelminths on the integuments of the Strongylate nematodes. The digestive system showed an ample epithelial vacuolation in the intestinal wall, as well as swelling and destruction in the mitochondria and endoplasmic reticulum.

[The results of micromorphological and histochemical studies of the musculocutaneous sac of nematodes in the suborder Oxyurata after anthelmintic exposure].

The paper presents the results of studies of the effects of anthelminthic agents on the in tegumentary tissues of nematodes from the Oxyurata suborder. All used anthelmintics causes varying structural changes in the integumentary tissues of Oxyurata. At the same time, there is swelling and loosening of the cuticle, its detachment from the subcuticular layer, vacuolization of the hypodermis and the plasma part of muscular cells, as well as irreversible changes in the cellular organoids of the hypodermis and muscular cells (destruction of canals of the endoplasmic network and the Golgi apparatus, mitochondrial membrane damage, nuclear pyknosis or lysis etc.

[Kidney reactivity in helminthiases and after anthelmintic treatment].

The paper provides and analyzes the data available in the literature and the authors' own findings of the structural and functional disturbances in the hosts' kidneys in various helminthiases and following the use of anthelminthic agents. The authors have established the common regularities of renal responses in helminthiases and revealed the specific features of responses to individual groups of anthelminthic agents depending on their dosage and use duration.

[Structural disorders in the tissues of nematodes of the suborder Ascaridata after exposure to anthelmintics].

The paper analyzes the authors' original findings and the data available in the literature concerning the structural changes in the tissue of Ascaridae after exposure to anthelmintics. The subject of the study of structural changes occurring in the digestive and genital systems represented As. canis lumbricoides, Toxocara mystax, Ascaridia galli.
