    Opis:
    The paper deals with methods facilitating the preparation of oncospheres of the cestode, Hymenolepis diminuta, for experimental studies. Described in detail are procedures for the infection of the definitive hosts with the oncospheres; collection and artificial hatching of oncospheres; purification of hexacanths; preparation of extracts from the hexacanths; and preparation of hexacanths for electronmicroscopic studies.

    Opis:
    The aim of the studies was to obtain some more accurate data on the amoebicidal effect of Entizol (Polfa) both on experimental E. histolytica infections and on the in vitro growth of the amoebae. The in vitro experiments were performed on four E. histolytica strains (two virulent and two avirulent); thr minimal amoebicidal concentrations of Entizol were higher from concentrations of Flagyl (Specia) and similar to the concentrations of emetine hydrochloride (Burroughs Wellcome a. Co.). In experiments in vivo, rats and guinea-pigs were infected parallelly with two virulent strains of E. histolytica; in the control of experimental amoebiasis, Entizol was as patent as Flagyl and mme effective than emetine hydrochloride.

    Opis:
    White rats (10) were infected with RH Toxoplasma gondii strain administering a Toxoplasma suspension on 7 occasions at 3-day intervals (2 ml of the peritoneal exudate from infected mice, at the dilution of 1:10). The obtained rat sera gave a positive reaction in the complement fixation test with Toxoplasma antigen (1:10-1:160). The electroproteinograms of immune sera (paper electrophoresis, staining according to Grassman-Hannig, photodensitometric measurements) were found to contain albumins and globulins α₁ and α₂, β, γ; as compared with the sera from non-infected rats there were hyperproteinemia and increase in β- and γ- globulins. The inactivation of sera at 56° did not affect the electroproteinogram pattern. Similar results were obtained by electrophoresis of immune sera on gel agar, with the difference that the γ-globulin fraction was extended to γ₁ and γ₂ subfractions. Immunoelectrophoresis (according to Grabar-Williams' and Scheideger's methods) of immune sera, as compared with those of non-infected rat sera, showed more conspicuous precipitation lines in the zones α₂, β and γ as well as a more clear-cut line corresponding to β₂M subfraction. The inactivated sera: gave a smaller number of precipitation lines. Preliminary studies by microdiffusion and agar gel techniques revealed the presence of 5 precipitation lines in the immune sera and only 3 lines in the normal ones. The inactivation of sera diminished the number of precipitation lines to 2 in immune sera, and to 1 in those of non-infected rats. Quantitative determinations of the fractions are under way.

    Opis:
    The acethylcholine level was determined by pharmacologic method in properly selected experimental and control groups of mice. Selection was made as to the strain, age, body weight and time that elapsed since the induction of experimental infection. After isolation of the diaphragm, inactivation of choline esterase by physostigmin, acetylocholine was extracted in a solution at pH of 3. The contraction of the dorsal muscle in leech, due to the effect of extracts from the diaphragm of infected and control muscles were compared with those that occurred under the influence of colutions obtained from cristalline acethylcholine. The experiments were made at 2, 3, 4, 5, 6, and 12 weeks of infection. The acethylcholine level in the diaphragmatic muscle of Trichinella-infected animals was found to be higher than that of normal ones (fig. 1), and to show an increasing tendency up to the 4th week of infection; the subsequent decrease was lower at 12 than at 2 weeks p. i.

    Opis:
    The experiments were made on 180 hens aged from 1 day to 10 weeks. The animals were infected peroral, subcutaneously or intraperitoneally. The material for infection (RH strain) was used as exudate of mice (trophozoite) or as organs of rats or rabbits infected a year ago (cysts). Investigated was also the possibility of infection in healthy hens through direct contact with diseased ones. The items taken in consideration were as follows: (1) clinical picture, (2) hematologic examinations includimg number of erythrocytes, leukocytes, white cell count, (3) serologic studies using complement fixation and dye tests, (4) effect of food on the mechanism by which hens get infected per os (alkaline, neutral or acid reaction), (5) anatomo-pathologic, microscopic studies and isolation of strain. The results obtained prompt the following conclusions: (1) experimental toxoplasmosis of hens is difficult to induce and the moment of infection food seems to play a major role in the mechanism of infection. The mortality of hens is lower than in other animals infected in the same way and conditions, and even spontaneous cure may occasionally take place; (2) in peroral infection food seems to play a major role in the mechanism of infection. The administration of alkaline food increases the chance of infection; (3) in experimental conditions healthy hens may contract infection from diseased ones through direct contact; (4) hematologic studies do not seem to be of important diagnostic value, whereas the reduction in the number of erythrocytes may indieate an evolution of pathologic process; (5) Serologically (CFT and DT) the presence of antibodies is not an invariable finding, the positive reactions showing comparatively low titres.
