a b s t r a c t zinc deficiency in man is characterized by skin lesion, alopecia and has been linked to growth retardation and mental disturbance. for supplementation purposes zinc is currently presented as its sulfate salt, from which uptake by the body is poor, necesseting the administration of high doses. this leads to a range of unpleasant side effects. in order to increase the bioavailab...
background: this research was conducted to evaluate the potential benefits of zinc sulphate in the prevention of radiation induced mucositis in patients who are being treated for head and neck cancers. materials and methods: forty patients with proven cancers of head and neck were randomly divided into 2 equal groups that either received zinc sulphate or placebo (control group). patients who re...
in this research nickel zinc ferrite nanoparticles with composition of ni1-xznxfe2o4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °c for 5 hours. the structure of nanoparticles was studied using x-ray diffraction pattern. the lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticles depend on zinc concentration. the crystal...
To study the effect of zinc sulfate rates on response of bread wheat cv. Cahmran to terminal heat stress conditions in Ahvaz, Iran, this experiment was conducted at the research farm of Agricultural and Natural Resources Sciences University of Khuzestan, Iran in two cropping cycles (2015-2016 and 2016-2017). The experimental design was split plot arrangements in randomized complete block design...
Background & Aims: Diabetes mellitus is associated with changes in testicular tissue. Here, the effects of co-administration of zinc and vanadium sulfate on testicular damage in diabetic animals were studied. Materials & Methods: Moderate diabetic hyperglycemia was induced by injection of streptozotocin (STZ) 40 mg/kg, ip. Five groups of animals were selected (n=5). Group I: As no...
The effect of foliar application of zinc sulfate and seaweed on qualitative and quantitative characteristics of local Kermanshah cantaloupe (Cucumis melo L., Cantalupensis Group) cv. Kalak was investigated. After sowing seeds in the field, the plants were sprayed in three stages including the 4-6 leaf stage, flowering and after the fruit set. The experiment had a factorial design based on the r...
The impacts of zinc oxide nanoparticles on embryonic development following oocyte stage exposure are unknown and the underlying mechanisms are sparsely understood. In the current investigation, intact nanoparticles were detected in ovarian tissue in vivo and cultured cells in vitro under zinc oxide nanoparticles treatment. Zinc oxide nanoparticles exposure during the oocyte stage inhibited embr...
The percentage and rate of germination and proper establishment of seedlings are important factors contributing to higher yield per unit area. As an essential element for plant growth and development, Zinc plays a critical role in many metabolic processes, and also has a positive effect on seed germination. The effects of seed priming with concentrations of 0.5, 1 and 2 percent zinc sulfate on ...
The aim of this study was to assess the effect of adding nanoparticles to N1 acrylic resin intended for artificial sclera, in terms of the color stability, microhardness, and flexural strength of the resin. Three hundred samples of N1 acrylic resin were used: 100 samples for color stability and microhardness tests (each test was performed on the opposite side of each sample), and 200 samples fo...
OBJECTIVES To find a suitable method for detecting zinc sulfate in adulterated urine. METHODS Two rapid spot tests to detect the presence of zinc sulfate in urine were developed. RESULTS Addition of 3 to 4 drops of 1N sodium hydroxide solution to approximately 1 mL of urine containing zinc sulfate led to the formation of a white precipitate, which was soluble in excess sodium hydroxide. In ...
