The elemental homeostasis of the blood plasma did not significantly differ depending on the region of residence, except for the potassium level (by 1.3 times greater for Russians) and strontium (by 10 times higher among the inhabitants of the Northern region of Azerbaijan). In patients with focal pulmonary tuberculosis, there were no significant differences in the content of elements in the blood plasma. With pulmonary tuberculosis, accompanied by decomposition processes, the content of calcium, copper, zinc and iron in blood plasma significantly increases in comparison with healthy people. Analysis of the level of these macro- and microelements can be used to determine the transition of the early form of pulmonary tuberculosis to infiltrative and/or cavernous forms, in which the patient becomes epidemiologically dangerous to others.展开更多
Changes of various mineral elements (P, K, Ca, Mg, Fe, Mn, Zn and Na) contents in roots and leaves of S. sagittifolia were studied with treatment of different Cu2+ concentrations (5 μM, 10 μM, 20 μM and 40 μM) aft...Changes of various mineral elements (P, K, Ca, Mg, Fe, Mn, Zn and Na) contents in roots and leaves of S. sagittifolia were studied with treatment of different Cu2+ concentrations (5 μM, 10 μM, 20 μM and 40 μM) after 15 days. The results showed that: 1) Cu accumulated in roots of S. sagittifolia in large quantities, while Cu content in leaves showed no significant change;2) It can be seen from the changes of macroelements that Cu2+ treatments had inhibited the absorption of P, K, Ca, Mg in roots of S. sagittifolia, but the contents of P, K and Mg in leaves were higher than those in the roots in all Cu2+ treatment groups;3) It can be seen from the changes of microelements that Cu2+ treatment promoted the absorption of Fe, inhibited absorption of Mn, Zn and Na in roots of S. sagittifolia, and hindered the transport of various micro-elements from roots to leaves. In all the Cu2+ treatment groups, contents of Fe, Mn, Zn and Na in leaves were lower than those in the roots;4) The critical concentration of Cu2+ to S. sagittifolia was 5 μM. It could be seen from the above results that exogenous added Cu2+ of different concentrations broke the balance of various mineral elements in S. sagittifolia, which would exert a significant impact on numerous metabolic pathways and physiological processes.展开更多
