[Activity of the anthelmintic agent trichlorophen on the models of human helminthiasis]. / Aktivnost' otechestvennogo antigel'mintika trikhlofena na modeliakh gel'mintozov cheloveka.

Trials of trichlorophen have shown its high efficacy on models of cestode infections: hymenolepiasis (at the adult and cysticercoid stages of development on three types of animals: outbred albino mice, albino rats and golden hamsters), preimaginal echinococciasis alveolaris, larval alveolar echinococciasis (at the early stage of development of the parasite in experiments on cotton rats). The high nematodical activity of trichlorophen was first found on models of trichocephaliasis in DBA/2y mice, nippostrongyloidiasis (in in vitro experiments), and aspiculuriasis in outbred mice. The agent proved to be ineffective at the tissue developmental stage of Hymenolepsis nana (H. nana), the dwarf tapeworm, in albino mice, during experimental opisthorchiasis in golden hamsters. It showed a low efficacy in treating trichinosis in outbred albino mice. Unlike carbamatebenzimidazoles, trichlorophen was inactive at the tissue stage of H. nana; it exerted no effects on the eggs of a dwarf tapeworm in trichinosis. Trichlorophen was also inactive in treating experimental opisthorchiasis in golden hamsters.

[Experimental chemotherapy of echinococcosis. 13. The effect of mebendazole in combination with a vegetable oil on the larval cysts of Echinococcus multilocularis and the reaction of the infested host to long-term administration of the preparation]. / Eksperimental'naia khimioterapiia ékhinokokkozov. Soobshchenie 13. Vliianie mebendazola v sochetanii s rastitel'nym maslom na larvotsisty mnogokamernogo ékhinokokka i reaktsiia invazirovannogo khoziaina na dlitel'noe vvedenie preparata.

The use of mebendazole as a suspension in vegetable oil enhanced the efficiency of treating experimental Echinococcus granulosus infection in outbred albino rats without increasing the dose of the drug. A sharp reduction in platelet count in the blood of the infected animals treated and untreated suggests that thrombohemorrhagic complications might be in echinococcosis. Thrombopenia in the treated animals appeared to be steady-state. A decrease in a rapid immune response in the mebendazole-treated rats, as compared to the untreated ones, is likely to be a consequence of a significant fall of antigenic immune stimulation due to suppression of the parasite's viability with the drug and to be an indicator of therapeutical efficiency.
