Effects of Aerobic Exercise on Uric Acid, Total Antioxidant Activity, Oxidative Stress, and Nitric Oxide in Human Saliva

Antioxidant compounds play a significant role in preventing and scavenging free-radicals by reducing oxidative stress and providing protection to humans against degenerative diseases and infections. Obviously, antioxidant molecules of plant origin are pivotal to combat the oxidative harm in cells. Present work intended to evaluate the antioxidant capacity of the fruits of Spondias pinnata. Methanol extracts of the fruits at two stages of maturity were prepared and investigated by various antioxidants analyses such as total antioxidant activity, reducing power and radical scavenging assays (DPPH, nitric oxide and hydrogen peroxide). Its total phenol, flavonoid and tannin contents were also determined. Spondias pinnata fruit extracts exhibited effective antioxidant activity and its IC50 values of the unripe fruits were 65, 66, 72.23, 83.25, 66.75 ?g/ml and ripe fruits were 124.24, 92.50, 97.66, 144.10, 72.25 ?g/ml, for total antioxidant activity, reducing power, DPPH radical scavenging, nitric oxide radical scavenging and hydrogen peroxide scavenging assays respectively. The extracts, especially unripe fruit extract had good amounts of total phenolic and flavonoid contents which might contribute the antioxidant activities considerably. It is evident from the study that the fruits of S. pinnata possessed potent antioxidant activity and it can be considered as a good dietary choice among the underutilized fruits as well as common fruits. Therefore, wild mango may be a good choice of antioxidants of plant origin for dietary and pharmaceutical uses.

The Difference

Serum total antioxidant activity (TAA), albumin and uric acid were measured on admission, and for the next 2 days in 56 patients suffering myocardial infarction, 20 of whom received streptokinase. The ‘antioxidant gap’, the difference between the serum TAA and the sum of the serum albumin and uric acid activity, was calculated. No significant changes in serum total antioxidant activity were observed in either group of patients between admission, day 1 and day 2. However, a decline in the ‘antioxidant gap’ after myocardial infarction was associated with a significantly higher mortality.

Total Antioxidant

The state of the blood antioxidant system in the patients presenting with acromegaly. The objective of the present study was to evaluate the total antioxidant activity (TAA) of blood plasma, the levels of non-protein thiols and 2-thyobarbituric acid-active products (TBA-AP), superoxide dismutase (SOD) and catalase (CAT) activities as well as ceruloplasmin (CP) level in the patients presenting with acromegaly. It was shown that plasma TAA and SOD activity in this patients was on the average 20 and 30% lower respectively than in the control subjects. At the same time, the TBA-AP and CP levels increased by 50 and 40% respectively. These data suggest the development of oxidative stress in the acromegalic patients.
