Effect of zinc on the content of chemical elements in the lung tissue during obesity in the experiment.

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. These elements should be given more attention in considering biological processes including alimentary obesity.

[Changes in alkaline phosphatase activity and blood phosphorus levels in healthy persons and patients with peptic ulcer]. / Kolebaniia aktivnosti shchelochnoi fosfatazy i soderzhaniia fosfora v krovi zdorovykh i bol'nykh iazvennoi bolezn'iu.

Venous blood total phosphatase activity, its thermostable fraction, and inorganic phosphorus levels were measured thrice within 20-64 min in the course of registration of regular motor activity of the gastrointestinal tract in 38 men aged 18 to 57 (9 healthy and 29 with peptic ulcer). These parameters changed within a wide range over the mentioned period; besides, they depended on the individual features of the organism. Using the chi 2 test at the 5% significance level the authors have demonstrated that total blood alkaline phosphatase activity is increased by the end of a regular cycle in the gastroduodenal system. For more accurate assessment of venous blood total alkaline phosphatase and its thermostable fraction activities and inorganic phosphorus level repeated measurements should be carried out within an hour.
