Abstract
The article presents the results of a study of the element status of residents of different ethnic groups (Koryak, even, mestizo) Magadan region. By atomic emission and mass spectral analizovs inductively coupled plasma quantity content of co, cu, Fe, Zn, si, al, cd, Pb, sn, Hg hair. there was a slight deviation of the content of some essential elements (copper, iron, zinc) in aboriginal and Mtis on average. it is suggested that this phenomenon is caused by adaptation to the conditions of the indigenous population of the north. these low levels of heavy metals - aluminum, cadmium, lead, tin, cobalt, mercury, indicates the relative well-being of the environment in terms of pollution with toxic elements. the higher silicon content in the hair of aboriginal and Mtis is consistent with the data that the Magadan region is silicic province. Variability of the most studied trace elements higher in the Mtis compared with the natives. High individual variability of chemical elements can be the result of an imbalance element in disadaptative organism to the environment, or a manifestation of the individual characteristics of the organism. the possible consequences of deficiency and excess of trace elements in the indigenous population of the north.
Highlights
This study was undertaken to examine the effect of dietary probiotics on yearling hybrids of russian and siberian sturgeon, based on hematological profile and piscicultural performance
In Control group, probiotic was not applied in diet but in treatment groups, probiotics «Bacell», «Monosporin», and «Prolam» was administered in feed at a concentration of 2%
Probiotics addition to diet had the effect on erythrocyte count, hemoglobin, leucocyte count, percent of lymphocyte, serum total protein, percent of neutrophile and monocyte The results suggest that probiotics can stimulate immune parameters hybrids of russian and siberian sturgeon and can be successfully used in fishfarming
Summary
Отмечено незначительное отклонение содержания некоторых эссенциальных элементов (меди, железа, цинка) у аборигенов и метисов от среднероссийского уровня. Полученные низкие показатели тяжелых металлов – алюминия, кадмия, свинца, олова, кобальта, ртути свидетельствуют об относительном благополучии окружающей среды в плане загрязнения токсичными элементами. Повышенное содержание кремния в волосах аборигенов и метисов согласуется с данными о том, что Магаданская область является кремневой провинцией.
