Low Concentrations

The physiological and biochemical responses to increasing NaCl concentrations, along with low concentrations of gibberellic acid or spermine, either alone or in their combination, were studied in mungbean seedlings. In the test seedlings, the root-shoot elongation, biomass production, and the chlorophyll content were significantly decreased with increasing NaCl concentrations. Salt toxicity severely affected activities of different antioxidant enzymes and oxidative stress markers. Activities of antioxidant enzymes, superoxide dismutase (SOD), and catalase (CAT) increased significantly over water control. Similarly, oxidative stress markers such as proline, malondialdehyde (MDA), and hydrogen peroxide (H2O2) contents also increased as a result of progressive increase in salt stress. Combined application of NaCl along with low concentrations of either gibberellic acid (5 µM) or spermine (50 µM) in the test seedlings showed significant alterations, that is, drastic increase in seedling elongation, increased biomass production, increased chlorophyll content, and significant lowering in all the antioxidant enzyme activities as well as oxidative stress marker contents in comparison to salt treated test seedlings, leading to better growth and metabolism. Our study shows that low concentrations of either gibberellic acid or spermine will be able to overcome the toxic effects of NaCl stress in mungbean seedlings.

Behavioural Tests

Lead (Pb) exposure induces oxidative stress causing imbalance in antioxidant enzymes, cognitive impairments and neurodegeneration. This study investigated the neuroprotective and antioxidant properties of sulphoraphane (SFN) on Pb-induced neurotoxicity of adult Wistar rats. Forty animals (150 ± 20 g) were divided into four groups (n=10): Group A received normal saline as placebo; Group B received 50 mg/kg body weight (bw) of Lead only; Group C received a combination of 50 mg/kg bw of Lead and 50 mg/kg bw of SFN; Group D received 50 mg/kg bw of SFN only. All administration was through oral gavages for 28 days; animals underwent behavioural tests (Morris water and Y- mazes); and thereafter sacrificed and brains extracted. Biochemical estimations of antioxidants (superoxide dismutase, reduced glutathione, and catalase), oxidative stress markers (malondialdehyde, nitric oxide, and hydrogen peroxide), neurotransmitters (dopamine, serotonin, and norepinephrine) and hippocampal histology were done. The results showed significant increase in escape latency, norepinephrine and oxidative stress markers with concomitant decrease percentage correct alternation, serotonin, dopamine and antioxidant enzymes in Pb exposed rats compared with the control. However, the co-administration of SFN and Pb significantly attenuated Pb neurotoxicity. Sulphoraphane is capable of ameliorating oxidative stress induced neurobehavioural deficits and hippocampal neurochemistry caused by Pb exposure in Alzheimer’s type animal model of neurodegenerative disorder.

Enalapril Treatment

Oxidative stress has been suggested to play a role in hypertension and hypertension induced organ damage. This study examined the effect of enalapril, an antihypertensive drug, on oxidative stress markers and antioxidant enzymes in kidney of spontaneously hypertensive rat (SHR) and Nω-nitro-L-arginine methyl ester (L-NAME) administered SHR. Male rats were divided into four groups (SHR, SHR+enalapril, SHR+L-NAME, and SHR+enalapril+L-NAME). Enalapril (30 mg kg−1day−1) was administered from week 4 to week 28 and L-NAME (25 mg kg−1day−1) was administered from week 16 to week 28 in drinking water. Systolic blood pressure (SBP) was measured during the experimental period. At the end of experimental periods, rats were sacrificed; urine, blood, and kidneys were collected for the assessment of creatinine clearance, total protein, total antioxidant status (TAS), thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD), and catalase (CAT), as well as histopathological examination. Enalapril treatment significantly enhanced the renal TAS level (P<0.001) and SOD activity (P<0.001), reduced the TBARS levels (P<0.001), and also prevented the renal dysfunction and histopathological changes. The results indicate that, besides its hypotensive and renoprotective effects, enalapril treatment also diminishes oxidative stress in the kidneys of both the SHR and SHR+L-NAME groups.
