Pašaliniai reiškiniai gydant medaminu nėra dažni ir nelabai išreikšti,- paprastai jie pasireiškia tik tokiom alerginėm reakcijom, kaip dilgėlinė, odos niežėjimas, bei dispepsiniai reiškiniai. Nutraukus preparato naudojimą jie paprastai praeina savaime.Side effects with medamine treatment are uncommon and mild, and usually only occur with allergic reactions such as hives, itching, and dyspepsia. They usually disappear spontaneously after discontinuation.

Pateikti duomenys rodo, kad veikimo spektro platumu medaminas pralenkia senesni antihelmintiką mebendazolą ir sėkmingai taikomas gydymui nuo parazitų poliinvazijos.The data presented indicate that, in the spectrum of action, medamine outperforms the older anthelmintic mebendazole and has been successfully applied in the treatment of parasitic polyplasia.

II. BIOLOGINIAI TYRIMAIII. BIOLOGICAL STUDIES

Siūlomų junginių toksiškumas baltosioms žiurkėms, sveriančioms 50-100 g, buvo tiriamas pagal standartinę metodiką / Litchfield J. T., Wilsoxom F.J., Fharmacol. Exp. Therap. 1949, 96, p. 99-113 / įvedant įvairias tiriamos medžiagos dozes baltosioms žiurkėms į skrandį. Vandeninės preparatų suspensijos buvo įvedamos individualiai, peroraliai, dozuojant 4000 mg/kg gyvo svorio. Gyvūnų būklė buvo stebima savaitę laiko.The toxicity of the proposed compounds to white rats weighing 50-100 g was investigated according to standard methodology / Litchfield J. T., Wilsoxom F.J., Fharmacol. Exp. Therap. 1949, 96, p. 99-113 / by administering various doses of the test substance to the stomach of white rats. Aqueous suspensions of the preparations were administered orally, at a dose of 4000 mg / kg body weight, orally. The condition of the animals was monitored weekly.

Nurodyta siūlomų preparatų dozė nesukėlė bandomųjų žiurkių žuvimo. Nebuvo pastebimų nukrypimų nuo normalios gyvūnų būklės, jie liko judrūs, gerai ėdė pašarą.The indicated dose of the proposed formulations did not result in death of the rat rats. There were no noticeable deviations from the normal condition of the animals, they remained agile and ate the feed well.

Gauti duomenys rodo, kad nauji junginiai, pasižymi labai žemu toksiškumu ir 4000 mg/kg dozėje (peroraliai) nesukelia žymesnių nukrypimų nuo fiziologinės normos.The data obtained indicate that the novel compounds with very low toxicity and at 4000 mg / kg (oral) do not cause significant deviations from the physiological norm.

Toksiškumo tyrimų rezultatai pateikiami 9 lentelėje.The results of the toxicity studies are presented in Table 9.

Naujų junginių antihelmintinis aktyvumas buvo ištirtas su šunimis, vištomis, avimis. Antihelmintinio aktyvumo tyrimams 10-15 kg svorio šunys buvo eksperimentiškai užkrėsti Echinococcus granulosus protoskoleksais po 2000 kiekvienam individualiai.The anthelmintic activity of the new compounds was tested in dogs, chickens, sheep. For anthelmintic activity studies, dogs weighing 10-15 kg were experimentally challenged with Echinococcus granulosus protozolecules of 2,000 each individually.

Po 7 dienų užkrėstiems šunims įvesdavo tiriamųjų junginių vandenines suspensijas, stabilizuotas emulgatoriumi Twin-80, dozuojant po 150 mg/kg individualiai. Po 5 dienų gyvūnai buvo užmušti, o junginių efektyvumas įvertintas, lyginant likusių helmintų skaičių kontroliniuose ir bandomuosiuose gyvūnuose (8 lentelė).After 7 days, the infected dogs were administered aqueous suspensions of test compounds stabilized with Twin-80 emulsifier at a dose of 150 mg / kg individually. After 5 days, the animals were sacrificed and the efficacy of the compounds evaluated by comparing the number of residual helminths in control and experimental animals (Table 8).

Antihelmintinis siūlomų junginių aktyvumas tirtas taip pat su viščiukais, eksperimentiškai apkrėstais helmintais Ascaridia gaili.The anthelmintic activity of the proposed compounds was also investigated in chickens experimentally infected with helminth Ascaridia gaili.

Invazinių askaridžių (Ascaridia gaili) kiaušinėlių kultūra gauta pagalThe culture of invasive ascaridia (Ascaridia gaili) eggs was obtained according to

P.T. Tverdochlebovo (1965) metodiką/”MaTepna.ibi κ HayuHOH κοΗφερεΗΐηηι Bcecoio3Horo očtnecTBa rejibMHHTo.ioroB” M., 1965,q.l,c.206-210.) Kiekvienas eksperimentinis viščiukas gavo po 200 vnt. invazinių askaridžių kiaušinėlių. Helmintams pasiekus lytinio subrendimo stadiją (nustatomą pagal koprologinius tyrimus), bandomiesiems viščiukams įvesdavo individualiai per zondą į skilvį tiriamuosius junginius po 100 mg vienkartinę dozę 1 kg svorio. Po junginių įvedimo eksperimentinius viščiukus laikė po vieną atskirame narvelyje, jų ekskrementus surinkdavo ir perplaudavo ant tinklo vandeniu, tokiu būdu atskiriant žuvusius parazitus ir juos suskaičiuojant.P.T. Tverdochlebov (1965) / "MaTepna.ibi κ HayuHOH κοΗφερεΗΐηηι Bcecoio3Horo očtnecTBa rejibMHHTo.ioroB", 1965, q.l, c.206-210.) Each experimental chicken received 200 pieces each. of invasive ascarid eggs. Once the helminths reached the stage of sexual maturation (as determined by coprologic studies), the test chickens were individually injected intraperitoneally with a 100 mg single dose per kg body weight. Following the introduction of the compounds, experimental chickens were housed individually in separate cages, and their excrement was collected and washed on the net with water, thereby isolating and counting dead parasites.

Bandomuosius paukščius užmušdavo praėjus 7 dienoms nuo tiriamųjų preparatų įvedimo ir atlikdavo helmintologinį jų žarnų skrodimą. Antihelmintinių junginių aktyvumą nustatydavo lygindami žuvusių helmintų, išsiskyrusių po preparato davimo, skaičių su helmintų, rastų atlikus helmintologinį skrodimą, skaičiumi.The test birds were sacrificed 7 days after the introduction of the test preparations and were subjected to helminth autopsy. The activity of anthelmintic compounds was determined by comparing the number of dead helminths released after administration of the preparation with the number of helminths found after anthelmintic autopsy.

Duomenys pateikti 6 lentelėje, rodo, kad siūlomi nauji junginiai yra aktyvūs prieš askaridžių invaziją viščiukams. Pažymėtina, kad šie preparatai parodė aukštą intensefektyvumą vištų askaridiozės atveju, naudojant dozę 100 mg / kg, tuo tarpu, kai žinomas prototipas -mebendazolas- aukštu aktyvumu nepasižymi. Antihelmintinį siūlomų junginių aktyvumą tyrė taip pat ir ant ėriukų, spontaniškai užsikrėtusių skrandžio-žarnyno strongiliatais (Strongylata). Ėriukų, užsikrėtusių skrandžio-žarnyno trakto strongiliatais atrinkimą atliko avininkystės fermoje, pasižyminčioje aukštu strongiliatinės invazijos ekstensyvumu, pasinaudojant diagnostinių helmintoovoskopinių tyrimų rezultatais. Užkrėstus ėriukus laikė atskiruose narvuose. Preparatus įvesdavo individualiai, peroraliai 20 mg/kg gyvo svorio dozėje, vandeninės suspensijos pavidalu. Po jų įvedimo sekdavo gyvulių būklę. Antihelmintinio aktyvumo nustatymui, praėjus 7 ir 10 dienų po preparatų įvedimo, atlikdavo helmintoovoskopinius tyrimus.The data presented in Table 6 indicate that the proposed novel compounds are active against ascarid invasion in chickens. It is noteworthy that these preparations exhibited a high intensity of activity in chicken ascaridiosis at a dose of 100 mg / kg, whereas the known prototype, mebendazole, does not exhibit high activity. The anthelmintic activity of the proposed compounds has also been studied in lambs spontaneously infected with gastrointestinal strongilates (Strongylata). The selection of lambs infected with gastrointestinal strongilates was carried out in a sheep farm with a high degree of strongilate invasion, using diagnostic helminthovoscopic results. The infected lambs were kept in separate cages. The formulations were administered orally individually at a dose of 20 mg / kg body weight in aqueous suspension. After their introduction, the condition of the animals was followed. Helminthovoscopic examinations were performed 7 and 10 days after administration of the products for anthelmintic activity.

Bandymų ant ėriukų, spontaniškai užkrėstų skrandžio-žarnyno trakto strongiliatais duomenys pateikiami 8 lentelėje.The results of tests on lambs spontaneously infected with gastrointestinal strongilates are shown in Table 8.

Avių strongiliatozių atveju aukštas antihelmintinis aktyvumas išaiškintas preparatams naudojant juos dozėje 20 mg/kg gyvo svorio, tuo metu, kai prototipas -mebendazolasparodė aukštą aktyvumą, tik 100 mg/kg dozėje.In the case of sheep's strongillathiosis, the high anthelmintic activity was elicited by formulations at a dose of 20 mg / kg body weight, whereas the prototype -mebendazole showed high activity only at a dose of 100 mg / kg.

Po tiriamųjų preparatų įvedimo nebuvo pastebėta jokių nukrypimų nuo fiziologinės normos. Gyvuliai gerai ėdė pašarą ir gėrė vandenįNo physiological abnormalities were observed following the administration of the study agents. The animals ate the feed well and drank water
