BACKGROUND Hepatitis B is the major cause of chronic hepatitis and cirrhosis in Iran. Sanitation and immunization is one of the most effective measures for prevention of the disease which is now widely used in developing countries. However, the immune response to the vaccine varies by age. OBJECTIVES To determine the effect of zinc sulfate on immune response to hepatitis-B vaccine in elderly....

The purpose of this study was to evaluate the effect of addition of zinc sulfate to conventional and resinmodified glass ionomer restorative materials. The samples were prepared by addition of zinc sulfate to glass ionomer at different concentrations. The samples were tested for fluoride, zinc and aluminum release at different time intervals. The antibacterial activity of the restorative materi...

stabilizer such as cane sugar to liquid lime-sulfur and evaporating to dryncss. Self-boiled lime-sulfur is made by utilizing the heat of hydration or slaking of quicklime, CaO, to carry on the reactions with sulfur. Ammonium polysulfide and sodium polysulfide are made by passing hydrogen Sulfide gas, H.^S, into ammonium or sodium hydroxide containing excess sulfur. It is supposed that the chemi...

Zinc supplementation decreases the morbidity of lower respiratory tract infection in pediatric patients in the developing world. We sought to determine if zinc mediates a specific inhibitory effect against the major cause of pediatric lower respiratory tract disease, respiratory syncytial virus (RSV). We determined the in vitro inhibitory effect of three zinc salts (zinc acetate, lactate, and s...

The effect of foliage sprayed zinc sulfate on berry development of Vitis vinifera cv. Merlot growing on arid zone Zn-deficient soils was investigated over two consecutive seasons, 2013 and 2014. Initial zinc concentration in soil and vines, photosynthesis at three berry developmental stages, berry weight, content of total soluble solids, titratable acidity, phenolics and expression of phenolics...

AIMS Cirrhotic patients commonly have a liver zinc deficiency, which may aggravate liver fibrosis due to the lack of antioxidative effects of zinc. This study examined the ability of polaprezinc, N-(3-aminopropionyl)-l-histidinato zinc, to prevent fibrosis in a rat model of thioacetamide (TAA)-induced hepatic fibrosis. MAIN METHODS Liver cirrhosis was induced by orally administering TAA for 2...

the study was designed to evaluate the impact of rhizobium bacteria and mycorrhizal fungi and iron sulfate was performed on chickpea plants. treatments rhizobium bacteria (inoculated and non-inoculated), mycorrhizal fungi (glomus mosseae, glomus intraradices and non-inoculated) and various amounts of iron sulfate fertilizer (0, 40 and 80 kg per hectare) with a factorial experiment in a randomiz...

In this investigation, the effect of zinc excess andits interaction with ascorbic acid on some growth parameters (root and shoot, fresh and dry weight, leaf blade area and length of root and stem), proline content, soluble sugars and starch plant were studied on canola. Experimental plants were treated with different concentrations of zinc sulfate ie. 0.7 (control), 50, 100, 250, 500 and 700 mM...

ZnCl2 over a very narrow concentration range was found to be mitogenic for hamster lymph node cells but not for thymocytes or splenocytes. Maximal leucine, [3H]uridine, and [3H]thymidine incorporation. Addition of 10 micron ZnCl2 was found to greatly enhance the stimulation observed with the B-lymphocyte mitogen lipopolysaccharide but not with dextran sulfate or the T-lymphocyte mitogen lipopol...
