Issledovanie sobak v napravlenii toksoplazmoza pri pomoshhi PCK i intradermal'nojj reakcii s toksoplazminom

Shepherd dogs (276), males, at the age of ca. 1 year, from various regions of Poland, were examined. The complement fixation test with the antigen obtained from the exudate of infected mice and intracutaneous test (0.1 ml of toxoplasmine 1:100-1:1000, reading after 24-28 hours, control test with spleen exudate from healthy mice) were performed paralelly. A positive result of both tests was obtained in 10 dogs (4%): in 52 dogs (19%) it was found to occur only with the romplement fixation (titre 1:3-1:8) and in 30 ones (11%) only with the intracutaneous test

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

Patterns and determinants of the horizontal and vertical intra-industry trade of regions: panel analysis for Spain & Poland

Most of the empirical studies in the literature on intra-industry trade are conducted at the country level. Countries, however, differ in terms of granularity and internal heterogeneity. In the present study we empirically identify the determinants of the overall IIT as well as its horizontal and vertical components in the trade of Spanish and Polish NUTS-2 regions with all existing trade partners over the period 2005–2014. In order to obtain unbiased results, we utilize a semi-mixed effect model, estimated with the PPML method. We estimate the models jointly for all Spanish and Polish regions and then disjointly in a comparative manner – in order to identify incongruities of reaction to the various factors investigated. These include both traditional factors and a number of unorthodox factors such as regional path dependence, quality of regional institutions, the core or peripheral status of the reporting region.Tomasz Brodzicki, Tomasz Jurkiewicz, Laura Márquez-Ramos and Stanisław Umińsk

287 sera were examined by means of the complement fixation reaction, applying the cold and warm method. 282 were human and 5 rabbit sera. The results of these examinations may be summarized as follows: 1) Positive results were obtained: by the warm method - 5,92%, by the cold method - 14,79%. 2) The titre with the cold method is always higher than the titre obtained with the warm method. 3) The conformity of the results of the complement fixation, Sabin-Feldman's dye test and Frenkel's intradermal test amounts to 61.5% for the warm method and to 66.6% for the cold method. The conformity of the ,results of the complement fixation and Frenkel's intradermal test amounts to 54.8% for the warm and 58.06% for the cold method. The conformity of the results of the complement fixation test and the dye test amounts to 84% for both methods

The complement fixations (CFT) and intradermal tests (IDT) were carried out in 565 children, including 280 mentally deficient, 179 deaf ones, and a control group of 106 normal subjects. The results are presented in table 1. Similar examinations were made in 104 mothers of mentally deficient. 50 mothers of the deaf and in 49 mothers of normal children. The results are presented in table 2
