Oxidative Responses

Background:: Current study evaluated the protective potential of quercetin against lindane induced toxicity in mice brain. For investigation, mice were allocated into four groups; First group was control. Second group was administered with oral dose of lindane (25 mg/kg bw) for 4 consecutive days. Third group was exposed to quercetin (40 mg/kg bw) and in fourth group, quercetin was administered 1 hour prior to the exposure of lindane. Objective:: Two major objectives were decided for study. First was to create lesions in the brain by lindane and; second was to evaluate the neuroprotective potential of quercetin. Methods:: To study oxidative responses, level of thiobarbituric acid reactive substances (TBARS), protein carbonyl content (PCC), reduced glutathione (GSH), superoxide dismutase (SOD), Catalase (CAT), and glutathione peroxidase (GPx) were measured in brain homogenates. Three key step regulating enzymes of tricarboxylic acid (TCA) cycle viz citrate synthase (CS), pyruvate dehydrogenase (PDH) and fumarase were also assayed. Results:: Lindane treatment significantly enhanced the levels of TBARS (P<0.001),PCC (P<0.001), GPx (P<0.001), SOD (P<0.05), PDH (P<0.05) and fumarase (P<0.001) in brains of mice compared to control. Meanwhile, it alleviated GSH, CAT and CS (P<0.05) activity. Conclusion:: Pretreatment with quercetin in lindane treated group not only restored, previously altered biochemical parameters after lindane treatment and also significantly improved them too which suggests that quercetin is not only invulnerable rather neuroprotective against lindane intoxication.

Ashitaba, Angelica keiskei Koidzumi (AK), as a traditional medicine in Korea, Japan, and China, has been known as an elixir of life having therapeutic potential. However, there is no scientific evidence to support that Ashitaba can enhance or maintain muscle strength. To find a new therapeutic agent from the medicinal plant, we evaluated the anti-myopathy effect of chalcones from ethanol extract of AK (EAK) in cellular and animal models of muscle atrophy. To examine anti-myopathy activity, EAK was treated into dexamethasone injected rats and muscle thickness and histopathological images were analyzed. Oral administration of EAK (250 or 500 mg/kg) alleviated muscle atrophic damages and down-regulated the mRNA levels of muscle-specific ubiquitin-E3 ligases. Among ten compounds isolated from EAK, 4-hydroxyderricin was the most effective principle in stimulating myogenesis of C2C12 myoblasts via activation of p38 mitogen-activated protein kinase (MAPK). In three cellular muscle atrophy models with C2C12 myoblasts damaged by dexamethasone or cancer cell-conditioned medium, 4-hydroxyderricin protected the myosin heavy chain (MHC) degradation through suppressing expressions of MAFbx, MuRF-1 and myostatin. These results suggest that the ethanol extract and its active principle, 4-hydroxyderricin from AK, can overcome the muscle atrophy through double mechanisms of decreasing muscle protein degradation and activating myoblast differentiation.
