The present study has been designed to find out the antioxidant potency of composite methanolic extract on swimming-induced oxidative damage on packed erythrocytes in Wistar strain male albino rat. Extract was administered at the dose of 40 mg/100 g body weight/day/rat orally by gavage for 15 days period to experimentation followed by cotreatment of the aforesaid extract at the same dose for 28...
Objective: Vitex negundo, commonly known as “nirgundi” is widely used in traditional as well as in folk medicines to cure many ailments such as fever, rheumatism, gum and skin diseases and liver disorders, etc. The present study evaluated the antioxidant potency of hydroethanolic extract of Vitex negundo leaves (VNE) in Freund’s complete adjuvant (FCA) induced arthritis. Methods: Acute oral tox...
Phenolic compounds are present at very high concentrations in the bark of Acacia mangium. These compounds are known to have strong antioxidant activity and thus different beneficial effects on human health. Phenolic compounds in bark of A. mangium were extracted and their antioxidant activities were investigated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging and ferric-r...
OBJECTIVE To examine involvement of oxidative stress in the pathogenesis and vascular complications of diabetes. METHODS This cross sectional study was conducted at the Joint Laboratory Office (JLO), Dokkyo Medical University Koshigaya Hospital, Koshigaya, Japan from April 2010 to December 2011. Fasting glucose, glycosylated hemoglobin (HbA1c), serum lipids, urinary albumin excretion (UAE), a...
Allium sp. vegetables are widely consumed for their characteristic flavour. Additionally, their consumption may provide protection against cardiovascular disease due to their antiplatelet and antioxidant activities. Although antiplatelet and antioxidant activities in Allium sp. are generally recognised, comparative studies of antiplatelet and antioxidant potency among the main Allium vegetable ...
Human plasma haptoglobin (Hp) is classified according to three phenotypes: Hp 1-1, 2-1, and 2-2 attributed by their two common alleles 1 and 2. Clinically, the 2-2 phenotype is associated with the risk of cardiovascular diseases and diabetes mellitus in patients. In this study, we demonstrate that Hp is an extremely potent antioxidant, which directly protects low density lipoprotein from Cu(2+)...
Anthocyanins are secondary plant metabolites responsible for the blue, purple, and red color of many plant tissues. The phenolic structure of anthocyanins conveys marked antioxidant activity in model systems via donation of electrons or hydrogen atoms from hydroxyl moieties to free radicals. Dietary intakes of anthocyanins may exceed 200 mg/day, however, little is known about their antioxidant ...
The effect of bottle ageing on the antioxidant activity of Pinotage, Cabernet Sauvignon, Chardonnay and Chenin blanc wines, using the 2,2'-azino-di-(3-ethylbenzothialozine-suIphonic acid) radical cation (ABTS*) and 2,2-diphenyl-l-picrylhydrazyl radical (DPPH') scavenging assays, was determined. Storage at 0°C, 15°C or 30°C for a period of 12 months resulted in a significant (p < 0.05) decrease ...
Canned and bottled tea drinks contain not only green tea epicatechins (GTE), namely (-)-epigallocatechin gallate (EGCG), (-)-epicatechin gallate (ECG), (-)-epigallocatechin (EGC) and (-)-epicatechin (EC), but also four GTE epimers, namely (-)-gallocatechin gallate (GCG), (-)-catechin gallate (CG), (-)-gallocatechin (GC) and (-)-catechin (C). In the present study we examined the antioxidant acti...
this study aimed to investigate the potency of silymarin (smn) and melatonin (mel) on restoring the pancreatic cells in streptozotocin (stz)-induced diabetic rats. male wistar rats were divided into five groups, including: control (c), untreated diabetic (d), smn-treated diabetic (50 mg/kg, orally), mel-treated diabetic (10 mg/kg, i.p.), and smn plus mel-treated diabetic rats. diabetes was in...
