Fish and fish oils are the richest sources of ω-3 fatty acids. However, they are susceptible to lipid peroxidation due to
their high degree of unsaturation. In the present study, the level of thiobarbituric acid reactive material in various fish
oils available in the market with and without added Vitamin E was determined. The peroxide levels in fish oil heated to food
frying temperature of 180°C and the effect of addition of vitamin E has also been studied. The results indicate that the peroxide
levels in almost all the products available in the market were abnormally high irrespective of their Vitamin E content. This
might be due to the inefficient methods used for processing and storage of fish oils. Addition of vitamin E was found to have
a significant effect in lowering the rate of peroxidation of fish oil during thermal stress, showing that association of antioxidants
with ω-3 fatty acids lowers the rate of lipid peroxidation. 相似文献

The levels of total sialic acid, lipid bound sialic acid and fucose were estimated in the sera of patients with benign and
malignant tumours of breast. An increase was noted in all the three parameters, with a more marked increase in malignancy,
when compared with benign and controls. Consequent to surgery, there was an elevation in the serum levels of the above parameters
than the values prior to surgery and a decline was noted two months after surgery although none of the values reached the
normal range. These results suggest a close association of the glycoproteins with the tumour burden and further signify their
role in early detection and staging of cancer breast. 相似文献

The main objective of the study was to assess the oxidative stress in plasma and erythrocytes of rheumatoid arthritis patients
by measuring the levels of thiobarbituric acid reactive substances (TBARS), non-enzymatic antioxidants (vitamin E, C and reduced
glutathione) and enzymatic antioxidants [superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSHPx)]. This
study has been conducted on twenty-two adult female rheumatoid arthritis patients and an equal number of healthy subjects.
Elevated lipid peroxidation and multidirectional changes in the antioxidant defence system were noticed in patients with rheumatoid
arthritis. The enhanced lipid peroxidation accompanied by disturbance in antioxidant status indicates that rheumatoid arthritis
patients are more prone to free radical mediated oxidative damage. 相似文献

The aim of the present study was to evaluate the antihyperglycemic and antilipidperoxidative effects of ethanolic seed extract
ofTephrosia purpurea (TpEt) in streptozotocin induced diabetic rats. Hyperglycemia associated with an altered hexokinase and glucose 6 phosphatase
activities, elevated lipid peroxidation, disturbed enzymatic and non-enzymatic antioxidants status were observed in streptozotocin
induced diabetic rats. Oral administration of “TpEt” at a dose of 300mg/kg bw showed significant antihyperglcemic and antilipidperoxidative
effects as well as increased the activities of enzymatic antioxidants and levels of non enzymatic antioxidants. We also noticed
that the antihyperglycemic effect of plant drug (TpEt) was comparable to that of the reference drug glibenclamide. Our results
clearly indicate that “TpEt” has potent antihyperglycemic and antilipidperoxidative effects in streptozotocin induced diabetic
rats and therefore further studies are warranted to isolate and characterize the bioactive antidiabetic principles from “TpEt”. 相似文献

The effects of different fatty acid (FA) contents in diet on serum parameters, FA compositions of eggs and meat, and liver morphological changes were studied in Shaoxing laying ducks. A total of 264 ducks at 17 weeks were fed a control diet or a diet containing 30 g/kg fish oil (FO), 25 g/kg sunflower oil (SO), or 30 g/kg palm oil with 20 g/kg beef tallow (PBO). Malondialdehyde (MDA) content in the liver and the serum of ducks fed the PBO diet was significantly (P<0.05) higher than that of ducks fed the other diets. Triglyceride (TG) and total cholesterol (TC) levels were significantly lower (P<0.05) in ducks fed the FO diet. Serum TC also was lower in ducks fed the SO diet. Superoxide dismutase (SOD) activity was also affected by diets. The contents of polyunsaturated FAs (PUFAs) in eggs and meat were significantly higher (P<0.001) in ducks fed the FO and SO diets than in ducks fed the control diet. The level of C22:6 (n-3) FA in ducks fed the FO diet was significantly higher than that in ducks fed the other diets. However, the conversion efficiency of the longer-chain C20:5 (n-3) FA was higher than that of C22:6 (n-3). Ducks fed the PBO diet exhibited lipid droplet accumulation in the liver. These results demonstrate that a diet enriched with different FAs has strong effects on serum lipid levels and the deposition of PUFAs into tissue lipids. 相似文献

研究评价6周游泳运动对载脂蛋白E(apoE-/-)敲除的6周龄大鼠脂质代谢和动脉粥样硬化的影响。大鼠分为对照组(n=7)和运动组(n=7)。运动组大鼠进行6周递增负荷游泳运动,每周均按照第一天10分钟,每周5天(每天增加10分钟,直到连续运动1小时)。评价运动前和运动后血浆总胆固醇。处死大鼠后评价胸、腹主动脉粥样硬化的面积。体重、脂代谢两组结果相似。运动组的相关统计指数降低,表明apoE-/-大鼠游泳运动后动脉粥样硬化病变减少。但这种改变与脂肪代谢无关。 相似文献

Osteoporosis encompasses a wide spectrum of conditions associated with imbalance of osteoclastic and osteoblastic activities.
The increased activity of osteoclasts leads to increased free radical formation and hence lipid peroxidation. Present study
probes into the role of antioxidants as a palliative treatment for osteoporosis. It involved 50 healthy controls and 75 clinically
diagnosed osteoporosis patients. Both the groups underwent baseline assessment of biochemical markers viz. osteoblastic markers:
serum Alkaline phosphatase. Free or ionic calcium and Inorganic phosphorus, osteoclastic markers: serum Tartarate resistant
acid phosphatase and Malondialdehyde and the antioxidant status: serum Superoxide dismutase and Erythrocyte reduced glutathione.
The osteoporotic group was then divided into groups A (Vitamin E-Evinal 400 mg), B (Vitamin C-Celin 500 mg), C (Vitamin E+C-Evinal+Celin)
for antioxidant supplementation for a period of 90 days. The results reveal that there is significant fall in concentration
of serum MDA (p<0.001), TrACP (p<0.01). Improvement in antioxidant status is reflected by significant rise in concentration
of serum SOD (p<0.001) and erythrocyte GSH (p<0.001) after 90 days of antioxidant supplementation in osteoporosis. The findings
indicate that on the whole bone status improved with prolonged antioxidant vitamin supplementation, which can be used as a
palliative treatment for osteoporosis. The efficacy is not affected whether the vitamins are administered singly or conjointly. 相似文献

The plasma fractionation is a technology to separate therapeutic plasma proteins. The fractionation is carried out either
by solvent precipitation (ethanol) or recently by chromatography. During the process of chromatography lipids were found in
waste fraction. A new lipid rich lyophilised quality control (Q.C.) sera was prepared inexpensively using this waste plasma
fraction. This is probably the first attempt to prepare the Q.C. sera by large scale chromatographic method in India. 相似文献
