background: asthma is a multifactorial disease and its severity varies with the inflammatory grade. there are conflicting reports about the roles of trace elements in asthma. this study examined the effects of zinc (zn), copper (cu), and selenium (se) concentrations in sera of patients with allergic asthma attending ghaem hospital, mashhad, iran. methods: forty-nine patients, aged 10 to 50 year...
background: anzali wetland has been subjected to high levels of pollution due to contamination from several industrial sites in addition to agricultural chemicals. mussels have been widely used for monitoring pollution in aquatic ecosystems, because they, as filter feeders, bioaccumulate pollutants. therefore we decided to evaluate anodonta cygnea for its application as a bio-monitor for copper...
Lobsters were fed cadmium-rich oysters for 28 days, and the induction of cadmium metallothionein and its relation to concentrations of cadmium, copper, and zinc in the digestive gland and gills was determined. A portion of the tissues also was retained for determining the cytosolic distribution of these metals by gel filtration and ion-exchange chromatography. The digestive gland contained a ma...
Background: Psoriasis is a common and chronic inflammatory skin disease that has profound adverse effects on patients’ wellbeing. Trace elements are essential to biochemical processes in the body and are involved in immunological and inflammatory reactions such as keratinization and melanin formation. The aim of this study was to evaluate the essential metals in psoriasis in comparision with he...
Background: Some metals play an important role in biological reactions and metabolism of human body. Low and high concentrations of these elements can cause diseases and poisoning. This study was carried out in order to investigate the concentration of metals in inlet and outlet water of households in Ahvaz city, Iran in 2018. Materials and Methods: This was a cross-sectional descriptive stud...
Hemodialysis is being implicated in the development of metabolic disturbances, as complications have been observed and the role of trace metals in their development has been questioned. In 78 renal failure patients who underwent hemodialysis, serum levels of zinc and copper were determined before and after first hemodialysis. Acute and chronic renal failure patients were found to have lowe...
Hematological and biochemical parameters were determined in 82 West African Dwarf goats with foreign body rumen impaction (FBR) and 40 normal WAD goats without foreign body rumen impaction (WFBR) in order to evaluate their influence on the etio-pathogenesis of rumen impaction. The mean PCV (26.22%), RBC (9.03 X 106/µL), Hb (8.38g/dl) and MCHC (32.20g/dl) were significantly lower in FBR than in ...
In this study, a comparative analysis of metal-related neuronal vulnerability was performed in two brainstem nuclei, the locus coeruleus (LC) and substantia nigra (SN), known targets of the etiological noxae in Parkinson's disease and related disorders. LC and SN pars compacta neurons both degenerate in Parkinson's disease and other Parkinsonisms; however, LC neurons are comparatively less affe...
AIM To assess plasma zinc and copper concentration in individuals with autism. SUBJECTS AND METHODS Plasma from 79 autistic individuals, and 18 age and gender similar neurotypical controls, were tested for plasma zinc and copper using inductively-coupled plasma-mass spectrometry. RESULTS Autistic individuals had significantly elevated plasma levels of copper and Cu/Zn and lower, but not sig...
In the present study histological effects of copper and Zinc sulphate on, 250 Caspian beluga (Huso huso) fingerlings were studied. In this regard, fish of treatment groups were exposed to 0.1, 0.2, 0.4, 0.6, 0.7 and 0.8 mg/l of copper and 5, 25, 50, 75, 80 and 85 mg/l of Zinc sulphate during 4 days respectively. Behaviours and clinical signs of fish were recorded during the experiment. Samples ...
