Abstract Quest is still going on for a cheap, effective, and easily available remedy for chronic arsenic toxicity. This study was designed to investigate the effects of folic acid and tetrahydrofolate in lowering the arsenic burden in tissues. Rats received arsenic at 700 μg/day by gavage for 28 days except the control group. Arsenic accumulation was significantly lowered (p<0.05), in liver, kidney, heart, lung and skin in both the folic acid and tetrahydrofolate-treated groups compared to arsenic only treated group. The oxidative stress induced by arsenic treatment was reduced as evident by the reduction in rise of malondialdehyde level in both groups. But folic acid was found to be more efficacious compared to tetrahydrofolate. Article InfoQuest is still going on for a cheap, effective, and easily available remedy for chronic arsenic toxicity.

The Effect of Oral Administration of L-Tyrosine, Folic acid and Pyridoxine on Perphenazine Induced Catatonia in Rat
L-tyrosine, B6 and folic acid are involved in biosynthesis of DOPA and consequently dopamine. The aim of this study was to investigate the antiparkinsonian effect of these agents in perphenazine-induced catatonia in rats. Murprogo method or scored muscular rigidity, which is induced by a phenothiazine, was used to evaluate the antiparkinsonian effect of these agents. A significant decrease in m...

متن کاملInhibitory effect of arsenic on aerobic gut flora in rat.
An in vivo study was carried on rats to see the influence of arsenic on aerobic gut flora. A significant inhibition of gut flora was observed after 2 weeks of administration of arsenic (1 mg/L) ad libitum with a decrease in stool arsenic level and increase in liver arsenic level. However, this inhibitory effect of arsenic on gut flora was not observed in presence of vitamin E (1 mg/day) or sele...
متن کاملProtective Effect of Folic Acid against Apoptosis Induced by Ischemia/Reperfusion Injury in Rat Liver
The anti-apoptotic gene bcl-2 is located in mitochondria, but it is uncertain whether its expression affects hepatocyte survival in ischemia/reperfusion (I/R) injury. This experiment was designed to evaluate the role of folic acid in expression of bcl-2 in I/R in rat liver. Eighteen Wister rats were divided into sham-operated controlgroup (C) (n=6), I/R group (...
متن کاملHigh intake of folic acid attenuates 6-hydroxydopamine-induced Parkinsonism
Introduction: High levels of homocysteine (Hcy) might accelerate dopaminergic cell death through oxidative stress and excitotoxicity. Folate plays an important role in the control of plasma levels of Hcy. In this study, effect of supplementation with folic acid on the 6-hydroxydopamine (6-OHDA)-induced Parkinsonism in rat and also serum level of Hcy was investigated. Methods: Rats were fed ...
