BACKGROUND Recurrent Herpes Labialis (RHL) is one of most common infective vesiculoulcerative lesions. According to some studies administration of topical and/or systemic zinc compositions has been effective in treatment and prevention. This article aims to comparison of zinc level in healthy subjects and RHL patients in acute and convalescent phases. MATERIALS AND METHODS This was a retrospe...

The physical characteristics of ultrasonically sprayed indium-doped zinc oxide (ZnO:In) thin films, with electrical resistivity as low as 3.42 × 10-3 Ω·cm and high optical transmittance, in the visible range, of 50%-70% is presented. Zinc acetylacetonate and indium chloride were used as the organometallic zinc precursor and the doping source, respectively, achieving ZnO:In thin films with growt...

Zinc (Zn) and selenium (Se) exert regulatory activities on immune functions, while cadmium (Cd) is an immunotoxic agent. The object of this study was to detect effects of 10-4, 10-5, and 10-6 M Cd sulphate, Zn sulphate, and sodium selenite, and their combinations on human peripheral blood mononuclear cell (PBMC) proliferation and IFN-γ and TNF-α production. Only 10-5 M Zn sulphate significantly...

More than 80% of the world’s production of zinc from its concentrate is obtained by the roastleach-electrowin hydrometallurgical process. In the roast-leach process, very pure zinc sulphate solution must be prepared for zinc electrowinning, therefore, the purification process is one of the most important unit processes in zinc hydrometallurgy. The conventional methods for the zinc solution puri...

a pot experiment was conducted in a completely randomized design, to study the effect of zinc sulphate (znso4) and ascorbic acid(as) foliar application application 20 and 40 ppm was compared to the control (distillated water) on flowering gazania (gazania rigens l. daybreak red stripe).results were analyzed by spss software and duncan test. results showed that znso4 and as had positive effect o...

Solid waste dump site-based pollution is one of the colossal health concerns globally due to presence cellulose, starch, protein, and lipids, which a perfect nutrient for development biodegrading potential microbes. The current study aimed determine productive microorganisms biodegradation. Ten samples were collected from different areas Karachi sites. identification characterization isolates d...

introduction: citrus are one of the important orchard fruit production that after banana is second in production at the world level and every year, chemical fertilizers having most important role in increasing crops productions, but in long application of fertilizers cause soil destructions and polluting underground water. also soils of dry regions are very poor in organic matter level. nowaday...
