aluminum oxide nanoparticles are the most widely used nanoparticles in various industries.theincreasing use of nanoparticles in the past two decades and their entry into the industrial and non-industrialwaste water necessitates the assessment of potential effects of these substances in aquatic ecosystems. oecdstandard method was applied to determine the toxicity of this substance. after perform...

purpose: to investigate the effects of phosphide on some human biological systems in order to find a way to control it and facilitate the prevention and treatment of its poisoning.   materials and methods: in this study, 67 files of autopsy description, forensic pathology results and forensic toxicology were studied as nominal qualitative variables in terms of each type of histological changes ...

thus humans are constantly exposed to this element. Little has been known about it’s metabolism and toxicity until the mid twentieth century. Aluminum is present in all tissues and organs in the body and when there is excessive accumulation multiple organ systems are effected by this metal (1). The important diseases induced by aluminum toxicity include dementia, anemia, myopathy, bone and join...

A major effect of aluminum toxicity in plants is the disturbance of phosphorus assimilation. Wright (15) noted similar symptoms in beet plants grown in phosphorus-deficient media and in culture solution containing aluminum, while work at Aberystwyth (13) has shown that ryegrass lines resistant to aluminum toxicity require much higher levels of aluminum to dlevelop aluminunm toxicity/phosphorus ...

aluminum is present in very small amounts in living organisms but abundant in the environment. a growing literature links with the biochemistry of aluminum and also with a series of diseases in chronic renal failure patients on treatment with hemodialysis. the initial description of potential aluminum toxicity in renal failure patients relates to description of dialysis encephalopathy syndrome ...

Multifocal osteonecrosis is a rare disease; chronic use of corticosteroids is considered the main risk factor. Patients with chronic renal failure can develop aluminum toxicity, which can lead to osteomalacia and encephalopathy. An association between osteonecrosis and aluminum toxicity has been reported among patients with dialytic renal insufficiency. Occupational exposure to aluminum rarely ...

PURPOSE Deodorant use during radiation therapy for breast cancer has been controversial as there are concerns deodorant use may exacerbate axillary skin toxicity. The present study prospectively determined the use of both aluminum-containing and non aluminum containing deodorants on axillary skin toxicity during conventionally fractionated postoperative radiation therapy for breast cancer. ME...

The presented experiment was carried out to determine the effectiveness of the inducible nitric oxide synthase inhibitor aminoguanidine in modulating the toxicity of aluminum chloride on the nitrite levels, malondialdehyde concentration, reduced glutathione content, as well as cytochrome c oxidase activity of Wistar rats. The animals were killed 3 h and 30 days after treatment and the hippocamp...

In rats, gastrointestinal aluminum absorption and tissue distribution were altered by parathyroid hormone; the resultant tissue concentrations were similar to those observed in dialysis patients with a fatal encephalopathy. In dialysis patients, serum aluminum and endogenous parathyroid hormone concentrations are significantly correlated. These data suggest that aluminum toxicity in dialysis pa...
