متن کاملZinc is an essential trace element for spermatogenesis.
Zinc (Zn) plays important roles in various biological activities but there is little available information regarding its functions in spermatogenesis. In our current study, we further examined the role of Zn during spermatogenesis in the Japanese eel (Anguilla japonica). Human CG (hCG) was injected into the animals to induce spermatogenesis, after which the concentration of Zn in the testis inc...
متن کاملHistory of nutrition symposium: trace element nutrition and human health.
Discovery of the importance of trace elements in nutrition began in the 19th century with the chemical analysis of elements in biological samples and the demonstration that certain elements were essential for growth of microorganisms, e.g., essentiality of zinc for Aspergillus niger (Raulin 1869). The clinical investigations of Stockman (1893, 1895a and 1895b) in women with “chlorosis” and the ...
متن کاملRecent Findings in Trace Element Nutrition
Studies in South Australia in the 1930-40's showed that the coastal areas .and, to a lesser extent, the areas inland had inadequate levels of cobalt and copper for livestock health and production. Since these studies, selenium responsive conditions have been recognised in livestock depastured on the ironstone soils in the higher rainfall areas and also in isolated, but at present ill-defined, a...
