    The aim of this work was to find out the specifics of changes in endogenous intoxication, middle mass molecules (MMM) and erythrocyte intoxication index (EII) in the blood of animals for experimental asthma in different periods of its development and to correct them by thiotriazolin.Material and methods. Researches were carried out on 72 Guinea-pigs (males), which were divided into 6 groups for 12 animals in each of them. The last sixth group included animals that were treated by thiotriazolin. The drug thiotriazolin rate of 100 mg / kg intramuscularly since 23rd day of the experiment for 10 days was administered in the animals of sixth group. Experimental model of bronchial asthma was restored on Guinea-pigs by the V.I. Babych method (1979). In all groups of animals there were determined the middle mass molecules concentration in blood in the wave of 254 nm by I.A.Volchehorskiy, D.A.Dyatlova, E.I. Lvovska and others methods and EII by V.K. Kazymyrko V.I. Maltsev methods. Numerical results were adapted with static method using Student\u27s criteria.Results of the research. The highest level of endogenous intoxication in the blood was in the fifth group of Guinea pigs with asthma (33rd day), indicating the direct dependence of the antigenic effect on their severity. Using of the thiotriazolin within 10 days (from 23rd to 33rd day) caused the decrease of the MMM254 concentration and EII in serum compared with a group of Guinea pigs, that were not entered the medicine. It approved its treating effect.Conclusions. So, the research of middle mass molecules and erythrocyte intoxication index indicators in different periods of experimental asthma showed their gradual increase in serum of Guinea pigs with the greatest severity in 33rd day of the experiment. It might indicate the development of endogenous intoxication animals. But the using of thiotriazolin caused the decreasing of these indicators. That gives a reason to state its positive effect on some markers of endogenous intoxication and feasibility of further researches

    Peer Effects in Risk Taking

    This paper examines the effect of peers on individual risk taking. In the absence of informational motives, we investigate why social utility concerns may drive peer effects. We test for two main channels: utility from payoff differences and from conforming to the peer. We show experimentally that social utility generates substantial peer effects in risk taking. These are mainly explained by utility from payoff differences, in line with outcomebased social preferences. Contrary to standard assumptions, we show that estimated social preference parameters change significantly when peers make active choices, compared to when lotteries are randomly assigned to them

    Two Proton Emission with Electromagnetic Probes

    A model to study two-proton emission from nuclei induced by electromagnetic probes is developed. The process is due to one-body electromagnetic operators, acting together with short-range correlations, and two-body Δ\Delta currents. The model includes all the diagrams containing a single correlation function. The sensitivity of the cross section to the details of the correlation function is studied by using realistic and schematic correlations. Results for the 16^{16}O nucleus are presented.Comment: 9 pages, 8 figures, Contribution to the 6th. Workshop on "Electromagnetic Induced Two-Hadron Emission",Pavia, 200

    First record of Poecilochirus mrciaki Mašán, 1999 (Acari, Parasitidae) and its phoretic carriers in the Iberian peninsula

    We report for the first time the presence of Poecilochirus mrciaki Mašán, 1999 in the South of Europe, in the Iberian peninsula and on new carrier insects. Mites were collected from carrion insects, during a decomposition experiment carried out in the natural park “Aiako Harria” (Errenteria, Gipuzkoa). Most deutonymphs were found on the body of the necrophagous beetle Necrodes littoralis (Coleoptera, Silphidae). Other species of insects in families Geotrupidae, Staphylinidae (Coleoptera) and Calliphoridae (Diptera) were also transporting mites. All carriers were colonising or visiting the pig carcasses. Sampling lasted 3 months in the summers 2009 and 2010. Most mites were sampled from bloat to advanced decay. This is also the first record of P. mrciaki phoretic on flies (Diptera)
