Oxidative stress is implicated in Parkinson's disease (PD). Metallothioneins (MT), cytochrome P450 IIE1 (CYP2E1) and glutathione S-transferases alpha4-4 (GSTA4-4) are involved in oxidative stress-mediated damage. Altered dopamine transporter (DAT) and vesicular monoamine transporter-2 (VMAT-2) are also documented in PD. The present study was undertaken to(More)
It is believed that the enhanced capability of activated macrophages to resist infection is related to the remarkable increase in the production of oxygen metabolites in response to phagocytosis. Both the production of H2O2 and the oxidation of NAD(P)H are directly dependent upon NAD(P)H-oxidase. It has been established that the respiratory burst is due to(More)
Deoxynivalenol (DON) is a Fusarium toxin that causes a variety of toxic effects with symptoms such as diarrhoea and low weight gain. To date, no review has addressed the toxicity of DON in relation to oxidative stress. The focus of this article is primarily intended to summarize the information associated with oxidative stress as a plausible mechanism for(More)
Leishmania is known to elicit Th2 response that causes leishmaniasis progression; on the other hand, Th1 cytokines restricts amastigote growth and disease progression. In this study, we report the potential of two leishmanial antigens (65 and 98 kDa, in combination) which enhance strong macrophage effector functions, viz., production of respiratory burst(More)
Azadirachta indica is well known medicinal plant mentioned in ancient herbal texts. It has been extensively used in Ayurvedic, Unani and Homoeopathic medicine and has become a luminary of modern medicine. As part of our drug discovery program we isolated azadiradione from the ethanolic extract of seeds of A. indica and evaluated for in-vivo antiulcer(More)
Gastroprotective mechanism of peganine hydrochloride isolated from Peganum harmala seeds was investigated. Peganine hydrochloride was evaluated against cold restraint (CRU), aspirin (AS), alcohol (AL) and pyloric ligation (PL) induced gastric ulcer models in rats. Potential anti-ulcer activity of peganine was observed against CRU (50.0%), AS (58.5%), AL(More)
An association between excessive zinc (Zn) accumulation in brain and incidences of Parkinson's disease (PD) has been shown in several epidemiological and experimental investigations. The involvement of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and glutathione (GSH) in the pathogenesis of PD has also been proposed in a few studies. Despite(More)
Oxidative stress is one of the major players in the pathogenesis of maneb (MB) and paraquat (PQ)-induced disorders. N-acetyl cysteine (NAC), a glutathione (GSH) precursor and silymarin (SIL), a naturally occurring antioxidant, encounter oxidative stress-mediated cellular damage. The present study was aimed to investigate the effects of NAC and SIL against(More)
Experimental studies have shown that toxicant responsive genes, cytochrome P450s (CYPs) and glutathione S-transferases (GSTs) play a critical role in pesticide-induced toxicity. CYPs play pro-oxidant role and GSTs offer protection in maneb (MB) and paraquat (PQ)-induced brain and lung toxicities. The present study aimed to investigate the effect of repeated(More)
Pulmonary silicosis is a deadly disease which kills thousands of people every year worldwide. The disease initially develops as an inflammatory response with recruitment of inflammatory cells into the lung controlled by multiple cytokines. The question whether these cytokines exert biological functions through signal transducing pathway remains unanswered(More)
