The effects of omega 3 fatty acid supplementation on brain tissue oxidative status in aged wistar rats.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe omega 3 fatty acids play an important role in many physiological processes. Their effect is well documented in neurodegenerative diseases and inflammatory diseases. Also, aging as a biophysiological process could be influenced by eicosapentanoic acid (EPA) and docosahexanoic acid (DHA) components of fish oil. However there are not many studies showing the effect of PUFA (polyunsaturated FA) suplementation in eldery brain functions and the response to oxidative strees. The aim of this study was to investigate the effects of dietary omega-3 fatty acid supplementation on levels of lipid peroxidation and oxidant/antioxidant status of brain tissue in aged (24 months old) Wistar rats.
methodsAnimals were divided in two groups. Control group (n=8) was fed with standard laboratory food and received water ad libitum. Treated group (n=8) was also fed with standard laboratory food, water ad libitum and received fish oil capsules (EPA+DHA) for 6 weeks. Daily dose was 30mg EPA and 45mg DHA (capsules: 200mg EPA and 300mg DHA; in-house method). At the end of treatment animals were sacrificed and brains were collected and frozen on -80ºC. The levels of lipid peroxidation (malondialdehyde - MDA), activity of catalase (CAT) and activity of superoxide dismutase (SOD) were examined in cerebral cortex. Catalase activity was determined by measuring the decrease in absorbance (H2O2 degradation) at 240 nm for 3 min and expressed as U/mg protein. Total SOD (superoxide dismutase) activity was performed at room temperature according to the method of Misra and Fridovich. The extent of lipid peroxidation (LPO) was estimated as the concentration of thiobarbituric acid reactive product malondialdehyde (MDA) by using the method of Aruoma et al. The incorporation of fatty acids in cellular membranes was confirmed by gas chromatography.
resultsOur results showed that lipid peroxidation significantly decreased in treated animal group, where MDA concentration was 0.38±0.001 vs. 0.43±0.001 nM/ml (p<0.05) in control. However SOD activity increased significantly in treated animal group 1.57±0.24 vs. 4.12±0.15 U/gHb/L (p<0.01) in control. CAT activity decreased in treated group but not significantly.
conclusionIncorporation of omega-3 fatty acids after their supplementation had beneficial effects on brain tissue. Omega-3 fatty acids increased activity of SOD and decreased lipid peroxidation. Changes in oxidative/antioxidative balance are a result of EPA and DHA effects on lipids and enzymes of antioxidative system.
