To evaluate the effect of pre- or posttreatment of selenium (6 micromol/kg b.w., single intraperitoneal injection) in mercury intoxication, rats were exposed to mercury (12 micromol/kg b.w., single intraperitoneal injection). Exposure to mercury resulted in induced oxidative stress in liver, kidney, and brain tissues. Marked changes in serum biochemical(More)
Curcumin, a safe nutritional component and a highly promising natural antioxidant with a wide spectrum of biological functions, has been examined in several metal toxicity studies, but its role in protection against mercury toxicity has not been investigated. Therefore, the detoxification and antioxidant effects of curcumin were examined to determine its(More)
The effect of dose and duration of treatment with chromium on its distribution in certain vital organs and the blood of rats has been investigated. The accumulation of metal was highest in liver and kidneys, followed by testes, brain and blood and was rather more dependent on the dose than on the duration of exposure. The sub-cellular distribution in liver(More)
Sediment samples were collected for PAHs analysis (upstream, midstream and downstream) from the bank of the river Gomti in Lucknow city, India during 2005-2007. Total concentration of the PAHs ranged from 0.068 to 3.153 microg/g dry weight. A correlation existed between the sediment organic carbon content (f(OC)) and the total PAHs concentration with a(More)
BACKGROUND The effects of lead on the hematological system results in the inhibition of heme synthesis and in anemia. Lead may affect the absorption and metabolism of essential trace metals also. There is little information especially from the northern region of India regarding the relationship between blood lead levels>or=10 microg/dl and anemia in(More)
Protective effect of copper (Cu), zinc (Zn) or cobalt (Co) against lead (Pb) toxicity in rats was investigated. Trace metal administration together with Pb decreased the hepatic and renal uptake of lead and reduced the Pb-induced inhibition of blood delta-aminolevulinic acid dehydratase (delta-ALAD) activity. The hepatic uptake of Zn or Co was also(More)
Single doses of sodium cyanide (60 μmol/kg body weight s.c.) were administered to male Sprague-Dawley rats. The effect of this poison on the content of the trace elements zinc, copper and manganese was investigated in various organs after 30 min, 2 h, 24 h, 48 h and 1 week. The zinc content in the liver was elevated 24 h after this sublethal cyanide dose(More)
The role of selenium in protection against nephrotoxicity and hepatotoxicity of cadmium in rats was investigated. The administration of Cd (3 mg/kg, s.c.) for 3 days enhanced the urinary excretion of lactic dehydrogenase (LDH), glutamic oxaloacetic transaminase (GOT) and total proteins, decreased the renal activity of GOT and alkaline phosphatase (ALP) and(More)
In order to investigate the effects of lead exposure on lipid metabolism, rats were exposed to 200, 300 and 400 ppm lead in their drinking water for 12 weeks. The lead exposure resulted in induction of phospholipidosis in kidney and brain of the animals. While renal phospholipidosis was accompanied with depletion of renal cholesterol, phospholipidosis in(More)
Lead is a ubiquitous toxin, known to have adverse effects on the body even at low levels of exposure. In this review we explore whether low lead may be the principal or a major contributory cause of essential hypertension, and whether removal of lead from the environment may eventually reduce both the overall incidence of hypertension and the increased(More)
