Suppression of functional activity of macrophages by gadolinium chloride, suppressing the macrophage population and the endocytosis velocity, was studied in vivo. Injection of GdCl3 led to an increase in serum cholesterol concentration. Preliminary injection of GdCl3 to mice with lipidemia 24 h before poloxamer 407 reduced the concentrations of triglycerides and LDL during marked depression of macrophages (in 24 h).

In rats with obesity induced by high fat ration, the concentrations of K, Ca, Mn, Fe, Cu, Zn, Se, Br, Rb, and Sr were measured in the liver and lungs using synchrotron X-ray fluorescence analysis. Recombinations of inter-element correlations in the liver and lungs of rats receiving or not receiving additional Zn were observed under fasting conditions and after eating lard. Sr and Ca made the most pronounced contribution in the redistribution of correlations in the liver of obese rats.

The synchrotron radiation X-ray fluorescence technique (SRXRF) was applied to the determination of K, Ca, Mn, Fe, Cu, Zn, Se, Br, Rb, and Sr concentrations in the liver and lungs in Wistar rats. The animals in the experiment included (1) healthy rats, (2) rats with alimentary obesity (AO), and (3) rats with alimentary obesity that were being given zinc sulphate with water for a long time (АО+Zn). Each group was divided into two subgroups.

We found no deviations from normalcy in the content of chemical elements (K, Ca, Mn, Fe, Cu, Zn, Se, Br, Rb, and Sr) in the lungs of rats with mild alimentary obesity, but revealed redistribution of correlations between the elements indicating impaired metabolism in this organ. Zinc supplementation had no effect on the body weight and content of chemical elements (including zinc) in the lung tissue in rats fed high fat diet, but led to significant changes in the correlations between the elements. Bromine, rubidium, and strontium are actively involved in interelement interactions in the lung tissue.

Using a high-fat diet in experiment on rats received model alimentary obesity (AO). Adding zinc to the diet did not affect the severity of the AO. The concentration of K, Ca, Mn, Fe, Cu, Zn, Se, Br, Rb, Sr in the liver and lungs of rats with obesity in both groups did not differ from that of healthy animals.
