in order to study the effect of different levels of nitrogen and copper on yield and nutrients concentrations and nitrate in broccoli head, an experiment was conducted based on a factorial combinations of five levels of nitrogen (0, 100, 200, 300 and 400 kg/ha) and three levels of copper (0, 2.5 and 5 kg/ha) that were applied to soil as ammonium sulfate and copper sulfate respectively, in three...

Tests were conducted to determine the concentrations of copper sulfate needed to kill Flavobacterium psychrophilum, the cause of bacterial coldwater disease, either in vitro or on Rainbow Trout Oncorhynchus mykiss eggs. For the in vitro test, a plastic strip dipped in a solution of F. psychrophilum was exposed for 15 min to copper sulfate solutions of 0, 1, 5, 10, 20, 35, 50, 75, or 100 mg/L. B...

BACKGROUND Copper (Cu) is an essential trace element involved in normal reproduction but its overexposure may produce some detrimental effects. The aim of this study was to investigate the effects of copper sulfate poisoning on morphometery of mice ovarian structures and probable intracellular changes. METHODS Thirty mature female mice were randomly allocated to control and two treatment grou...

Copper sulfate has been used for many years as an algaecide and parasite treatment. The usage of copper has certain issues as there is a thin line that separates effective treatment levels from overdoses. Copper sulfate can be extremely toxic to fish under certain conditions. This study is focused on the effects of copper sulfate on some blood indices in Oncorhynchus mykiss during a 24 hour per...

In this research, copper borates are synthesized by the reaction of copper sulfate pentahydrate (CuSO4.5H2O) and tincalconite (Na2O4B7.10H2O). The experimental parameters are selected as 80C reaction temperature and 60 of reaction time. The effect of mole ratio of CuSO4.5H2O to Na2O4B7.5H2O is studied. For the identification analyses X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectr...

OBJECT Anemia and leukopenia caused by copper deficiency are well-documented consequences of long-term total parenteral nutrition. We measured the serum copper levels of bed-ridden patients receiving enteral feeding, and evaluated optical and ultrastructural features of bone marrow before and after copper supplementation. PATIENTS AND METHODS Serum samples were obtained from 15 bed-ridden eld...

This experiment was conducted to investigate the effects of different levels of oxidized fat (yellow grease) and copper sulfate on performance, carcass traits, blood metabolites and immune cells of broilers. This study was carried out as a 3 × 2 factorial experiment with 3 levels of oxidized fat (0, 2 and 4%) and 2 levels of copper sulfate (0 and 300 mg/kg) in 6 treatments, 3 replicates and 12 ...

the toxic impact of copper sulfate in lethal and sublethal concentrations was investigated on gill of grass carp, ctenopharynogodon idella . in this investigation, 27 specimens were used as control group and three treatment groups were treated with 2.5 and 5mg/l of copper sulfate. gill samples were collected from each treatment after 96hr and lesions were analyzed by light microscopy. in histop...

Objective: Fungal agents cause disease in virtually any susceptible hosts. In the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antifungals into hatching eggs. There is little information available describing the safety of the antifungal drugs on the birds embryonated eggs. The objective of this study was to investigate the efficiency of the...
