H2 receptor antagonist (H2RA) and proton pump inhibitor(PPI) are often used to treat gastric ulcers, in addition to the zinc-L-carcino-complex which is commonly adopted for such therapies. However, there have been no previous reports detailing the levels and distribution of zinc in human gastric mucosa. The aim of our current study is to clarify the relationship between Helicobacter pylori infection and trace elements such as zinc in gastric mucosa using particle induced X-ray emission (PIXE). Forty gastric ulcer patients were chosen as subjects of this study and divided into two groups. One is a new ulcer patients group(twenty nine cases). And the other, eleven of these patients had been prescribed zinc-L-carcino-complex (polapreZinc®), at a dose of 150mg/day for periods ranging from 16 to 20 weeks. The zinc levels in the gastric ulcer group were found to be significantly less than those of the control group and the concentrations of zinc in gastric mucosa were observed to increase following the administration of treatments containing this element.

This study aims to obtain an overview of trace elements concentrations in rocks, soils and plants from Puxiong lead-zinc mining area in Yunnan, China, and analyze the connection as well. Concentrations of Ba, Cd, Co, Cu, Mn, Pb, Zn, As, Sb, Hg, Sn, Ni and Sr among soils, rocks and three dominant plants in mining area, transition area and background were measured. Ratio parameter, bioconcentration factors (BF) and Pearson's correlation coefficients were used to analyze the relationship between these elements in different feature. The results indicate that rocks, soils and plants samples are all characterized by high concentrations of Pb, Zn and other associated elements in Puxiong lead-zinc mining area. Geochemistry of trace elements concentrations from rocks to soils, then to plants presents obvious characters of inheritance and variability. Whats more, three dominant plants are same in high concentration of Mn and low concentration of Cd, Hg, Co, but are huge different in bio-concentration factors.

Currently, there is no doubt about the prevailing influence of the level of physical activity of an individual on the functional state of the body. However, the available literature data on the impact of physical stress on the body's supply of trace elements and their distribution in tissues are largely contradictory. This review of available literature data provides an insight into the relationship between physical activity and microelement homeostasis. The influence of human physical activity on the exchange of toxic (lead, cadmium, Nickel, etc.) and essential trace elements, such as iron, selenium, copper, cobalt, chromium, and zinc is reviewed. Based on the analyzed works, it is concluded that in order to correct the metabolic and microelement status of a person during physical activity, the most reasonable and necessary is the modulation of homeostasis of zinc and selenium.
