apoptosis, a physiologic mechanism to eliminate unwanted cells, is also induced by ionizing irradiation, through production of free radicals. it has been demonstrated that antioxidants such as vitamin e are able to protect cells from damage caused by free radicals. taken together we found it reasonable to make an attempt to evaluate the protective effect of vitamin e against apoptosis. the irra...
malondialdehyde (mda) is widely used as a biomarker for assessing oxidative stress in biomedical fields. lipid peroxidation is a chain phenomenon resulting in the formation of various active compounds that result in cellular damage. biomonitoring of mda has been used in both in-vivo and in-vitro studies as a key biomarker for various disease patterns including hypertension, diabetes, atheroscle...
background: mannitol is present in the ethyol ® (the trade name of amifostine) as an excipient. the mechanism of radioprotection of amifostine is radical scavenging. since mannitol is another known radical scavenger, we studied the probable additive or synergistic effect of mannitol on the effect of amifostine. material and methods: mice were irradiated with co-60 γ -ray in the presence 400mg/k...
musa sapientum (m.sapientum) commonly known as ‘banana’ is widely used in bangladeshi folk medicine for the treatment of various ailments including diarrhea. hence, the present study was designed to investigate antidiarrheal, antioxidant and antibacterial potential of the methanolic extract of m.sapientum seed (mmss). the extract was studied for antidiarrheal property using castor oil and magne...
introduction: free radicals are molecules or atoms with single electron that results in reactions thus causing severe damages to the body’s macromolecules. by preventing the formation of free radicals, repairing damages caused by radical’s activities, increasing the excretion of the damaged molecules and minimizing the cellular mutation, the antioxidant defense system contrasts the damages caus...
free radicals are produced continuously in the cells as part of normal cellular function, however excess production might play a role in pathophysiology of many disease conditions, including cancer, alzheimer's disease, atherosclerosis and some of the drug-induced toxicity. many basic research studies and observational epidemiologic studies in human suggest that antioxidants can prevent oxidati...
background & aim: applications of synthetic antioxidant in food have side effects. in present study, the antioxidant potential of morus alba leaves, as natural antioxidant, was screened with cupric ion reducing assay (cuprac assay) and inhibition of lipid peroxidation. the aim of this study was to determine the total antioxidant activity of morus alba leaves. martial & methods: the fir...
murraya koenigii l. (rutaceae), commonly known as curry leaf tree, closely associated with south india where the word “curry” originates from the tamil “kari” for spiced sauces. curry leaves are a rich source of carbazole alkaloids which possess various biological activities such as antitumor, antioxidant and anti-inflammatory. curry leaf has a potential role in the treatment of diabetes. reser...
results and conclusions the analysis of covariance revealed that catalase activity significantly decreased in the copenhagen football test group after the assessment compared to regular football exercises group. meanwhile, the glutathione reductase values significantly increased (p < 0.05). the increase in glutathione reductase values led to the protection of erythrocyte metabolism through the ...
