The present study demonstrates the possibility of increased lipid peroxidation and protein oxidation in both maternal and
fetal erythrocytes as markers of oxygen radical activity during intrauterine growth retardation. The erythrocyte MDA levels
were significantly elevated in mothers of IUGR babies when compared to controls (p<0.01). The endogenous protein damage due
to oxidative stress was significantly higher in IUGR mothers when compared to controls (p<0.05). Similarly the proteolytic
activity in erythrocyte lysates against oxidatively damaged hemoglobin was significantly increased in mothers of IUGR babies
compared to controls (p<0.001).
In fetuses born with IUGR, both lipid peroxidation and proteolytic activity were significantly increased when compared to
normal newborns (p<0.01).
The result of this study indicates that oxidative stress was induced both in IUGR babies and their mothers which is manifested
as increased lipid peroxidation and protein oxidant damage. 相似文献

Oxidative stress is thought to be involved in the pathophysiology of malaria, especially in pregnancy where natural resistance
is markedly reduced. In the present study we investigated oxidative stress in 315 pregnant women out of which 159 had Plasmodium
falciparum malaria and 154 controls. We evaluated the level of lipid peroxidation products (MDA level) in the plasma, the
activity of erythrocyte antioxidant defense enzymes, superoxide dismutase (SOD, EC: 1.15.1.1) and catalase (Cat, EC: 1.11.1.6)
as well as the ability to resist oxidative stress by the FRAP (Ferric Reducing Ability of Plasma) assay. Total erythrocyte
protein levels were also examined. For the two groups of patients, several differences between the biochemical parameters
tested were found. Median parasitaemia in women with malaria was 25,392 parasites/μl of blood (Range1200–82000), while in
controls we had no parasites found in thin and thick smears. Levels of lipid peroxidation products (MDA) were significantly
higher in patients with parasitemia than in healthy asymptomatic volunteers (mean: 0.844 ± 0.290 and 0.384 ± 0.129 respectively,
p<0.001). This MDA level was higher in primigravidea and also correlates well with parasite density (p<0.001). Catalase activity
in erythrocytes of women with malaria did not differ statistically from that of controls. In contrast, SOD activity of patients
with malaria was found to be significantly higher than that of controls (mean: 0.7899 ± 0.2777 and 0.4263 ± 0.2629 respectively,
p<0.05). FRAP values declined, from parasitemic patients (1.4619 ± 0.6565) compare to controls (2.4396 ± 0.8883, p<0.05),
particularly in the first and third trimester of gestation (p<0.05 and p<0.01 respectively). Finally, total erythrocyte protein
concentrations of women with malaria did not differ from that of the controls. Our results suggest an imbalance between oxidants
and antioxidants in pregnant women suffering from malaria, a situation which could lead to severe damage for either the mother
or the fetus. Therefore, further research should be done to assess the potential benefits of antioxidant supplementation for
the pregnant women suffering from malaria. 相似文献

The present, study was conducted to determine the level of malondialdehyde (MDA) as an index of free radial induced lipid
peroxidation and antioxidant vitamins-vitamins A, vitamin C and vitamin E in 75 confirmed cases of urolithiasis. Significantly
high level of MDA (p<0.001) with significantly low levels of vitamin E (p<0.001) and vitamin A (p<0.001) with no significant
decrease in vitamin C (p>0.05) were observed in the plasma of urolithiasis cases as compared to normal controls. In conclusion,
it appears that a role of lipid peroxidation and oxidative function exists in the pathogenesis of urolithiasis. But, the exact
mechanism how this occurs remains to be elucidated. 相似文献

The objective of the present study is to evaluate the beneficial effect of tomatoes, which are rich source of Lycopene, relatively
a new carotenoid known to play an important role in human health and disease. In this study lipid peroxidation rate was measured
by estimating Malondialdehyde and the levels of serum enzymes involved in antioxidant activities like Super Oxide Dismutase,
Glutathione Peroxidase, Glutathione Reductase, Reduced Glutathione, in type-II diabetic group (n=40) and age matched control
group (n=50), and observed significantly lower levels of antioxidant enzymes and very high lipid peroxidation rate in type-II
diabetes when compared to control group (p<0.001). Short term supplementation with tomatoes (cooked) to diabetic group for
a period of 30 days, showed a significant improvement in antioxidant enzyme levels (p<0.001) and decreased lipid peroxidation
rate (p<0.001) suggesting the supplementation with tomato lycopene may serve as the best method of preventing the oxidative
stress in diabetic patients. 相似文献

Hyperglycemia and dyslipidemia in diabetes mellitus induce increased lipid peroxidation and peroxyl radical formation, an
important mechanism in genesis of microangiopathy. We took up a study on oxidative stress, measured by plasma MDA and antioxidant
vitamin status in type − 2 DM patients with and without retinopathy and compared them with a control non-diabetic group. Lipid
peroxidation marker MDA was significantly elevated (p < 0.001) in both the diabetic groups whereas, serum vitamin E and vitamin
C registered a significant fall (p<0.001) as compared to controls. Our correlation study revealed a significant positive association
between plasma MDA with both fasting and 2hr post prandial plasma glucose (r=0.81, p < 0.001, r=0.92, p <0.001) suggesting
the role of hyperglycemia in free radical production. Plasma MDA also depicted significant positive relation (p< 0.001) with
all lipid parameters except serum HDLc pointing the role of dyslipidemia towards lipid peroxidation. Plasma MDA level was
also found to be negatively correlated with both the vitamins (p<0.001, p<0.001) in the study group explaining their protective
consumption in the oxidative process prevailing in diabetic retinopathy. 相似文献

Phototherapy has been related to increased oxidative stress and lipid peroxidation. In the present study, thirty full term
jaundiced neonates with appropriate weight were analyzed before and after completion of phototherapy for malondialdehyde (MDA),
reduced glutathione (GSH), total thiols, vitamin C and superoxide dismutase (SOD) levels in hemolysate and albumin levels
in plasma. These parameters were analyzed in cord blood samples of 20 healthy neonates as control. It was observed that levels
of MDA were elevated significantly (p<0.001) in patients as compared to controls and that the levels increased significantly
after phototherapy (p<0.001). Levels of SOD were also found to be increased significantly as compared to controls and the
levels rose after phototherapy (p<0.001). On the other hand, the levels of non-enzymatic antioxidants such as GSH, total thiols
and vitamin C were significantly low (p<0.001) as compared to controls and the levels decreased significantly after phototherapy
(p<0.001). The plasma albumin levels also were found to be decreased significantly after phototherapy (p<0.01). Therefore,
phototherapy increases oxidative stress and should be used with care. 相似文献

The objective of the study was to observe the correlation between oxidative stress and antioxidants in myocardial infarct
patients with normal lipid profile. In the present study investigation of lipid peroxidation and antioxidants were done in
patients. This study was carried out on 165 AMI patients, (123 males and 42 females). The control group consisted on 165 normal
healthy age-sex matched subjects (123 males and 42 females). Levels of Superoxide dismutase, Glutathione Peroxidase, Catalase,
Malondialdehyde and Conjugated dienes were measured. The study found Superoxide dismutase, Glutathione Peroxidase, Catalase
were significantly lower in activities (p<0.001) in AMI patients compared to controls. The markers of lipid peroxidation namely
Malondialdehyde and Conjugated dienes were higher in AMI patients as compared to controls (p<0.001). The present study is
clearly suggestive of increased oxidative stress in AMI patients. Oxidative stress appears as an etiological factor for myocardial
infraction as a consequence the free radical scavengers levels are lowered in AMI patient. 相似文献

Serum malondialdehyde was measured in sixty-one falciparum malaria cases, which include thirty uncomplicated, and thirty-one
complicated with acute renal failure. Twenty-six healthy individuals were also studied as controls. Serum malondialdehyde
level was found to be significantly elevated in falciparum malaria induced acute renal failure cases when compared with uncomplicated
falciparum malaria (p<0.001) and healthy controls (p<0.001). A positive correlation with the raised urea, creatinine and bilirubin
levels were significant (r=0.62, p<0.025; r=0.65, p<0.05 and r=0.72, p<0.001 respectively) indicating the severity of complication
with rise of lipid peroxides in falciparum malaria induced acute renal failure cases. 相似文献

Coronary Artery Disease is the major cause of mortality and morbidity worldwide. Traditional risk factors account for only
half of the morbidity and mortality from coronary artery disease. There is substantial evidence that oxidative stress plays
the major role in the atherosclerotic process. The present study was undertaken to evaluate the level of lipid peroxidation
(by measuring malondialdehyde) and antioxidant enzymes (ceruloplasmin, glutathione, superoxide dismutase) in coronary artery
disease. Serum malondialdehyde levels and serum ceruloplasmin levels were significantly raised in all the subgroups of study
group as compared to control group (p<0.001). Whole blood glutathione levels and hemolysate superoxide dismutase activity
was significantly decreased in all the subgroups of study group as compared to control group (p<0.001). Above results suggests
that the patients of coronary artery disease show increased oxidative stress and decreased levels of antioxidant enzymes.
So it is recommended that the management protocol for coronary artery disease patients should include antioxidant supplementation
along with simultaneous lowering of lipid peroxidation. 相似文献

Repeated blood transfusion in beta thalassemia major patients may lead to peroxidative tissue injury by secondary iron overload.
In the present study, 72 children with beta thalassemia major were included. Serum levels of total lipid peroxides, Iron,
Total Iron Binding Capacity, Copper, Zinc, Vitamin E, plasma Total Antioxidant Capacity, activity of Erythrocyte Superoxide
Dismutase, were measured. The findings were compared with 72 age matched healthy controls irrespective of sex. A significant
increase in the levels of lipid peroxide and Iron (p<0.001), whereas, significant decrease in the levels of vitamin-E, Total
Antioxidant Capacity and Total Iron Binding Capacity (p<0.001) was observed. Serum Zinc was significantly increased (p<0.001)
with significant decrease in the levels of copper (p<0.001). Non Significant increase in the activity of Erythrocyte Superoxide
Dismutase (p>0.05) was found in the patients when compared with controls. This suggest that oxidative stress and reduced antioxidant
defense mechanism play an important role in pathogenesis of beta thalassemia major. 相似文献

Lipid peroxidation products and antioxidants were estimated in either blood, serum or erythrocytes of 25 cases of early and 25 of advanced senile (50–60 years) cataract and 30 persons of age matched healthy controls. Serum lipid peroxidation products (as malondialdehyde) were significantly higher in patients with early senile (0.25±0.05 μm/dl, P<0.05) and advanced senile cataract (0.29±0.05 μm/dl, P<0.001) as compared to healthy controls (0.22±0.07 μm/dl). Erythrocyte superoxide dismutase levels were lower in patients with early senile (730±60.5 units/gm Hb) and significantly lower in advanced senile (712±50.2 units/gm Hb, P<0.05) cataract than those in healthy controls (767±59.5 units/gm Hb). Serum α-tocopherol was significantly lower (P<0.05) in only advanced senile cataract (0.69±0.08 mg/dl) but not in early senile cataract (0.75±0.08 mg/dl) when compared with healthy controls (0.75±0.09 mg/dl). There was no significant difference in the erythrocyte concentration of reduced glutathione and serum levels of total proteins, β-carotene, vitamin A, ascorbic acid, calcium, magnesium and zinc. 相似文献

Premature coronary artery disease (CAD) is common in India. We, therefore, studied oxidative stress, dyslipidemia, and high
sensitivity-C reactive protein (hs-CRP) levels in young CAD patients. Present study consisted of male CAD patients below 40
years and age and sex matched healthy controls (n=30 each). Fasting blood samples were analyzed for serum lipid profile, malondialdehyde,
antioxidant enzymes and hs-CRP levels. Dyslipidemia was observed in 90% of the young CAD patients, of which 72.2% showed increased
serum triglycerides and decreased HDL-cholesterol. LDL-cholesterol levels were high in 77.8%. Serum malondialdehyde and hs-CRP
levels were increased significantly (p<0.0001) as compared to controls. hs-CRP levels were in high risk range in all the young
patients. However, glutathione peroxidase activity was reduced significantly (p<0.05). Our data suggests that elevated hs-CRP
levels along with dyslipidemia and oxidative stress adds to the predictive value of premature CAD in young Indians. 相似文献

Stroke is the third leading cause of death and foremost cause of disability. Based on studies in CAD patients, a focus has
been shifted on genetic and inflammatory markers as risk factors for stroke besides deranged lipid profile. The present study
was aimed to ascertain the role of Lipoprotein (a), C-Reactive protein (CRP) levels and lipids in patients of ischemic stroke.
The study was done in 82 subjects including 40 Computerized Tomography (CT) proven patients of ischemic stroke and 42 age
and sex matched controls. Complete biochemical parameters including lipid profile were carried out on autoanalyzer using standard
kits and reagents. Lipoprotein (a) [Lp(a)] was determined by immunoturbidimetric assay. Atherogenic indices (Total cholesterol/
HDL, LDL/HDL and Lipid Tetrad Index) were calculated using these lipid parameters. The CRP levels were measured semi-quantitatively
by latex agglutination test method. Out of 40 stroke patients, 38 had abnormalities in lipid profile (As per ATP III guidelines).
A significant difference was seen in serum cholesterol, LDL cholesterol and atherogenic indices between the patients and controls.
The difference in CRP levels in cases and control subjects was highly significant (4.78±0.72 mg/dl vs 0.76 ±0.70, p<0.001).
96.5% of patients with raised CRP had abnormal lipid levels also. CRP levels in stroke patients showed significant correlation
with total cholesterol and LDL (p<0.001), Lp (a) (p=0.002) and atherogenic indices (p<0.05). Raised CRP levels in stroke patients
were significantly associated with large territory infarcts, severe disability and poor functional outcome (p<0.05).Genetic
[Lp(a)], metabolic (deranged Lipid profile) and inflammatory factors (CRP) together are instrumental in causing cerebrovascular
arteriosclerosis leading to ischaemic stroke and can be used as important markers to identify patients at risk of severe stroke
and to institute aggressive preventive strategies. 相似文献

The objective of the study was to estimate the serum concentrations of oxidative stress markers-lipid hydroperoxide (MDA-Malondialdehyde),
lactate dehydrogenase (LDH), nitrite; and ferric reducing antioxidant power (FRAP) — a measure of total antioxidant capacity
in serum. Serum nitrite levels were high in fertile women than in infertile women (p<0.001), whereas MDA was high in infertile
women than in fertile group (p<0.018). On classifying the entire group of women with infertility based on the etiology, serum
MDA and LDH levels were higher in women with infertility due to unexplained factor than in women with other causes contributing
to infertility compared to controls (p<0.001, p<0.02). A positive correlation among serum prolactin and nitrite suggested
that hyperprolactinemia could contribute to infertility by inducing oxidative damage. Serum FRAP levels showed no significant
difference in the groups studied. Lipid peroxidation was high in women with unexplained infertility which may be due to hyperprolactinemia. 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 effect of oral administration of vitamin E for twenty-eight consecutive days on blood glucose, reduced glutathione levels,
antioxidant enzymes (superoxide dismutase and catalase activities), and levels of malondialdehyde (as an index of free radical-mediated
lipid peroxidation) was observed in the whole blood and liver of normal and alloxan-induced diabetic rats. It was found that
oral administration of vitamin E significantly (p<0.05) lowered the blood glucose level and increased the body weight of the
diabetic rats. The activities of superoxide dismutase and levels of reduced glutathione increased significantly (p<0.05) while
the level of lipid peroxidation decreased. 相似文献

Oxidative stress is implicated in the etiopathogenesis of a variety of human diseases. Therefore, in the present study, erythrocyte
lipid peroxidation, percentage hemolysis, antioxidant enzymes viz., glutathione reductase, glutathione peroxidase, superoxide
dismutase and plasma antioxidants viz., ceruloplasmin, vitamins A,E and C have been determined in 19 patients with tubercular
meningitis (TBM) and 50 normals. Six patients who were treated with antibiotics were considered for the follow up. The statistical
analysis was carried out by Mann Whitney U test and Wilcoxon rank sum test. Lipid peroxidation (P<0.02), percentage hemolysis
(P<0.001) and plasma ceruloplasmin (P<0.0001) of TBM patients were significantly higher, whereas erythrocyte glutathione reductase
(P<0.05) and plasma antioxidant vitamins A, E and C (P<0.01, P<0.05 respectively) were significantly lower than those of the
controls. In the follow up patients the glutathione reductase and catalase levels were significantly high (P<0.05) compared
to their pre-treated condition. Vitamin C and E levels have attained normal range. This study indicated that the blood antioxidant
status of TBM patients which was low compared to controls improved after treatment, suggesting the role of free radicals in
TBM. 相似文献

It has been proposed that oxidative stress plays an important role in male infertility. The aims of this study were to compare
seminal plasma levels of 15-F2t-isoprostane (8-iso-PGF2α), malondialdehyde (MDA), and total (sum of free and bound) homocysteine
(tHcy) from normozoospermic vs. asthenozoospermic men, and to examine the relationships between tHcy and lipid peroxidation
products. The study was a case-control study with a simple random sampling. The case group was consisted of 15 asthenozoospermic
males. This group was compared with 15 normozoospermic men. Seminal plasma levels of 15-F2α-isoprostane and tHcy were measured
using commercially available enzyme immunoassay (EIA) kits. MDA levels were determined by the thiobarbituric acid (TBA) assay.
The Mann-Whitney U test was used to compare two groups. Coefficients of correlation were calculated using Spearman’s correlation
analysis. All hypothesis tests were two-tailed with statistical significance assessed at the p value <0.05 level. MDA levels
were higher in asthenozoospermic subjects than in control subjects (0.72±0.06 μM vs. 0.40±0.06 μM; p<0.05). No differences
were seen in 15-F2α-isoprostane levels in asthenozoospermic subjects and controls (65.00±3.20 pg/ml vs. 58.17±4.12 pg/ml;
p>0.05). Interestingly, tHcy levels were to be slightly higher in asthenozoospermic subjects than in controls (6.18±1.17 μM
vs. 4.8±0.52 μM). Sperm motility was inversely correlated with seminal plasma 15-F2α-isoprostane and MDA levels, respectively
(p<0.05). In summary, seminal plasma levels of 15-F2α-isoprostane and tHcy showed no significant difference between normozoospermic
and asthenozoospermic men. Sperm motility was not correlated with seminal plasma levels of tHcy. No relationship was found
between tHcy and lipid peroxidation. 相似文献

New findings on organization of blood cell cytoskeleton represent an exciting aspect of modem cell biology and hematology,
which is an interesting investigation to study diabetes. The present study was undertaken in 150 subjects. Out of these, 30
subjects were controls (Group I) and 30 were type-2 diabetics without any complication (Group II), while remaining 90 subjects
were type-2 diabetics with complication (Group III). We determined erythrocyte spectrin and hemoglobin glycosylation and also
estimated plasma lipid peroxide, nitric oxide and erythrocyte glutathione peroxidase activity to assess the status of oxidative
stress. There was a significant increase in spectrin (P<0.001) and hemoglobin (P<0.001) glycosylation in Group II and III
as compared to Group I and spectrin glycosylation was nearly three times more as compared to hemoglobin, whereas plasma levels
of lipid peroxide (P<0.001) as well as nitric oxide (P<0.001) were found to be significantly increased and GPx activity (P<0.001)
was significantly decreased in Group II and III as compared to Group I. However, it was also observed that spectrin (P>0.05)
and hemoglobin (P>0.05) glycosylation was not significantly different in Group II and III. In contrast, there was significant
rise in lipid peroxide (P<0.001), nitric oxide (P<0.001) and fall in GPx activity (P<0.001) in Group III when compared to
Group II. Increased erythrocyte protein glycosylation and oxidative stress is clearly evident from our study. However, to
understand the exact interplay between these two mechanisms, further studies are required. 相似文献

In the present study, 58 diabetic patients (type II) comprising uncomplicated (27) and complicated (31) cases along with 38 healthy matched controls were investigated for glycosylated hemoglobin (HbA1), glycosylated serum proteins (GSP) and serum lipid profile viz. triacylglycerol, total cholesterol, HDL-cholesterol (HDL-C), VLDL-C, LDL-C and their ratios. HbA1 and GSP were significantly elevated in diabetic group as a whole when compared with controls (p<0.01), but comparison of mean values of complicated and uncomplicated group revealed (though higher in complicated) that the difference between two groups was not statistically significant (p>0.05). Follow-up studies showed that while GSP levels reflect variations in blood glucose over a shorter period of 15 days, those of HbA1 do so for about 3 months. HbA1 correlated with fasting blood glucose (p<0.01), whereas GSP showed correlation with both fasting (p<0.01) and postprandial (p<0.05) blood glucose. Hypercholesterolemia and hypertriacylglycerolemia were observed (p<0.01) in both the groups. However no significant change was seen in HDL-C (p>0.05) even after accounting for sex in both the groups. Interestingly TC:HDL-C was elevated significantly (p<0.01) in the above groups. These findings seem to suggest that at the levels of hyperglycemia, hypercholesterolemia and hypertriacylglycerolemia observed, some patients are prone to develop complications earlier. 相似文献
