Aluminum is the most widely distributed metal in the environment and is extensively used in modern daily life. Aluminum enters into the body from the environment and from diet and medication. However, there is no known physiological role for aluminum within the body and hence this metal may produce adverse physiological effects. The impact of aluminum on(More)
It has been postulated that the neurotoxic effects of aluminium could be mediated through glutamate, an excitatory amino acid. Hence the effects of aluminium administration (at a dose of 4.2mg/kg body weight daily as aluminium chloride, hexahydrate, intraperitoneally, for 4 weeks) on glutamate and gamma-amino butyrate (GABA), an inhibitory amino acid, and(More)
Both aluminum and ethanol are pro-oxidants and neurotoxic. Considering the possibilities of co-exposure and sharing mechanisms of producing neurotoxicity, the present study was planned to identify the level of aluminum-induced oxidative stress in altered pro-oxidant (ethanol exposure) status of cerebrum. Male rats were coexposed to aluminum and ethanol for(More)
Aluminum is an omnipresent neurotoxicant and has been associated with several neuropathological disorders. Cerebrum and cerebellum have been shown to face augmented oxidative stress when animals are exposed to aluminum and high doses of ethanol. To establish the link between oxidative stress and neurobehavioral alterations, the present study was conducted(More)
Alteration of glutamate and γ-aminobutyrate system have been reported to be associated with neurodegenerative disorders and have been postulated to be involved in aluminum-induced neurotoxicity as well. Aluminum, an well known and commonly exposed neurotoxin, was found to alter glutamate and γ-aminobutyrate levels as well as activities of associated enzymes(More)
The mechanism of aluminum-induced neurotoxicity is not clear. The involvement of glutamate in the aluminium-induced neurocomplications has been suggested. Brain glutamate levels also found to be altered in protein malnutrition. Alterations in glutamate levels as well as glutamate-α-decarboxylase in different regions of rat brain has been reported in(More)
Nucleic acid and protein content in various cellular fractions of different regions of the brain were investigated in male albino rats following aluminum (Al) exposure (at the dose of 15% of LD50 i.p. for 28 days) on either an adequate or inadequate protein diet. It was observed that there was a decrease in homogenate DNA content in the thalamic area (Th),(More)
Membrane damage is one of the important consequence of chromium, an environmental toxicant, to produce cytotoxicity, alpha-tocopherol, a membrane protectant can be used to reduce the chromium-induced membrane damage. In the present study, the impact of chromium in presence and absence of alpha-tocopherol was studied on plasma membrane of liver and kidney in(More)
The aluminium-induced neurotoxic consequences include, among other factors, dephosphorylation, phosphorylation as well as hyperphosphorylation of specific macromolecules. Accordingly, activities of phosphoesterases were measured in different regions of rat brain, maintained with either adequate or inadequate protein diet, following aluminium exposure. Male(More)
A variety of laboratory tests are available to assist in the diagnosis of alcohol consumption and related disorders. The levels of intake at which laboratory results become abnormal vary from person to person. Laboratory tests are particularly useful in settings where cooperativeness is suspected or when a history is not available. Several biochemical and(More)
