Afanasieva L. Morfological and functional state and correction of penetration of placenta barrier in cows

Object of research: permeability of placental barrier of cow for cadmium and lead. Purpose of research: the estimation of e morphological and functional state of an cow's placental barrier, permeability through it of cadmium and lead, revealing of influence of saponite and sulphur feeding and deducing of a tissue preparation "Fetoplacentat" on placenta barrier function. Methods of research: clinical, anatomic, histological, cy-tomorphological, biochemical, immunological, atomic-abcosorbtional spectrophotometria, statistical. Scientific novelty: for the first time is used complex research of an cow's placenta histostructure in connection with pe-netration through placental barrier of cadmium and lead in dynamics of pregnancy, the influence of the additive to a diet of saponite both sulfur and introduction of a tissue preparation on cytological and biochemical structure of blood, parameters of non-specific resistance and penetration of cadmium and lead through the cow's placental barrier during the dry period is investigated. Concentration of cadmium and lead in maternal and foetus parts of placenta, Varton's jelly tissue of umbilical cord, amniotic and allantoic liquids for the first time are determined and can be accepted as rough parameters at scientific researches of placenta barrier function. Degree of introduction: the results of job are used in the agricultural enterprises of a different type and in educational process of Zhitomir, Podilsk, Harkiv, Bila Tserkva and Lugansk agrarian higher educational institutions. Sphere (field of using): the data are intended for use by the science officers, teachers and students of faculties of veterinary medicine, experts of veterinary medicine and animal industries.
