Haemonehus contortus, Trichostrongylus co- lubriformia, Cooporia pumctata, Ostertagie circumc- inata, Nippostrongylus muris i Nemstospircides du- bius z rodziny Trichostrongylidne; 3. Ossephagostonum columbianum i Chabertia- ovina z rodziny Strongylidae; 4. Strongyloides ratti z rodziny Rhabddtidae; . Toxocarm canis, Toxascaris laonina i larwy Ascaria suum z rodziny Ascarididae; 6. Aspiculuris tetraptera z rodziny Oxyuridae* 7. Heterakie spumosa z rodziny Heterakidae.II. Tasiemce 1. Hymenolepis nana i Hymenolepis mierostoma z nadrodziny Taenioidea.Skutecznosc zbadano za pomoca prób na zwie-93 694 6 rzetach zakazonych pasozytami stosujac podawanie doustne i pozajelitowe. Zwierzeta poddawane ba¬ daniom bardzo dobrze znosily stosowane dawki.Nawet przy podawaniu dawek 10 razy do 100 razy wiekszych niz terapeutycznie potrzebna, zwierzeta doswiadczalne przezyly leczenie.Przyklad I. 96 g 4-acetyloaminoacetanilidu w 300 ml toluenu miesza sie w ciagu 6 godzin w temperaturze 20° z 76 g tlenochlorku fosforu. Na¬ stepnie wkrapla sie roztwór 60 g dwumetyloaminy w 200 ml toluenu i ogrzewa do wrzenia pod chlod¬ nica zwrotna w ciagu nocy. Po przeróbce analo¬ gicznej do opisanej w przykladzie I otrzymuje sie 27 g N-(4-acetyloaminofenylo)-N',N'-dwumetyloace- tamidyny o temperaturze wrzenia 190—20.0°/0,l ma Hg. Po rozpuszczeniu i wytraceniu zwiazek ten topi sie w temperaturze 131—134°C.Przyklad II. 98 g eteru 4-acetyloaminofenylo- acetyloiminoetylowego ogrzewa sie z roztworem 26 g dwumetyloaminy w 100 ml etanolu w ciagu 2 dni w temperaturze 28°, a nastepnie w ciagu 6 godzin w zamknietej rurze w temperaturze 120— 130°C. Po odparowaniu i destylacji otrzymuje sie 57 g N-(4-acetyloaminofenylo)-N',N'-dwumetyloace- tamidyny o temperaturze topnienia 131—134°. Ana¬ logicznie otrzymuje sie N-(4-acetyloaminofenylo)- acetamidyne przez reakcje eteru 4-acetyloiminofe- nylo-acetyloiminoetylowego z amoniakiem. Ten sam zwiazek powstaje takze przez reakcje 4-aminoace- tanilidu z eterem acetyloiminoetylowym. PL
