To correlate blood lead levels (BLLs) and oxidative stress parameters in pregnant anemic women. A total of 175 pregnant women were found suitable and included for this study. Following WHO criteria, 50 each were identified as non-anemic, mild anemic and moderate anemic and 25 were severe anemic. The age of all study subjects ranged from 24–41 years. At admission, BLLs and oxidative stress parameters were estimated as per standard protocols and subjected with ANOVA, Pearson correlation analysis and cluster analysis. Results showed significantly (p < 0.01) high BLLs, zinc protoporphyrin (ZPP), oxidized glutathione (GSSG), lipid peroxide (LPO) levels while low delta aminolevulinic acid dehydratase (δ-ALAD), iron (Fe), selenium (Se), zinc (Zn), haemoglobin (Hb), haematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), red blood cell (RBC) count, reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) and total antioxidant capacity (TAC) in all groups of anemic pregnant women as compared with non anemic pregnant women. In all groups of pregnant women, BLLs showed significant (p < 0.01) and direct association with ZPP, GSSG and LPO while inverse relation with δ-ALAD, Fe, Se, Zn, Hb, Hct, MCV, MCH, MCHC, RBC, GSH, SOD, CAT and TAC. Study concluded that low BLLs perturb oxidant-antioxidant balance and negatively affected hematological parameters which may eventually Pb to Fe deficiency anemia during pregnancy. 相似文献

The present study was designed to evaluate the lipid peroxidation and non-enzymatic antioxidants in pregnancyinduced hypertension
(PIH) compared with healthy normal pregnant and non-pregnant as controls. 75 cases were studied of which 25 were normal healthy
controls (Group A), 25 healthy pregnant women (Group B) of third trimester and 25 were PIH (Group C) of the same trimester.
In PIH, malondialdehyde a lipid peroxidation product was significantly increased as compared to normal pregnant and non-pregnant
controls. The nonenzymatic antioxidants like reduced glutathione, Vitamin-E, Vitamin-C and Vitamin-A were significantly decreased
in normal pregnants as compared to controls. A further significant decrease was noticed in PIH compared to normal pregnants.
A significant negative correlation was detected between lipid peroxidation and non-enzymatic antioxidant levels. Our study
clearly indicates a relationship between elevated lipid peroxidation, decreased non-enzymatic antioxidant in PIH. The measurement
of non-enzymatic antioxidants in plasma may be useful predictor of the likely development of PIH. 相似文献

Iron deficiency anemia is one of the causes that lead to significant mortality and morbidity among pregnant women and fetus. The present study was undertaken to explore oral iron supplementation can modify the metal contents in pregnant anemic women. Iron and folic acid supplementations was given to 500 anemic women (mild = 200, moderate = 200, and severe = 100) and 100 age matched non-anemic controls daily for 100 days. Blood index values and plasma trace minerals were estimated as per standard protocols. Haemoglobin and ferritin levels were found significantly increased (p < 0.001) in anemic and control subjects after treatment. Moreover, the serum transferring receptor levels and total iron binding capacity were found significantly decreased in all treated groups. Iron (Fe), zinc (Zn) and copper (Cu) levels were found increased (p < 0.01) after oral iron supplementation groups. Moreover, selenium (Se) manganese (Mn) and were found to be decreased in all treated groups. Data provides the conclusion that iron and folic acid supplementation recovered the essential trace minerals, except manganese, which may lead to various complications including peroxidation of vital body molecules resulting in increased risk for pregnant women as well as fetus. 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

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

Present study investigated the effects of isoproterenol-induced oxidative stress on hemodynamic and ventricular functions
in rats. Subcutaneous injections of isoproterenol (85 mg/kg for two consecutive days at 24 h interval) significantly decreased
myocardial antioxidant enzymes; superoxide dismutase, catalase and glutathione peroxidase in heart. Isoproterenol-induced
oxidative stress was also evidenced by significant depletion of reduced glutathione and increased formation of lipid peroxidation
product, thiobarbituric acid reactive substances along with depletion of myocyte injury specific marker enzymes; creatine
phosphokinase isoenzyme and lactate dehydrogenase. The deleterious outcome of oxidative stress on hemodyanmic parameters and
ventricular function were further evidenced by decreased systolic, diastolic and mean arterial blood pressure, heart rate,
ventricular contractility; [(+)LVdP/dt] and relaxation; [(−)LVdP/dt], along with an increased left ventricular end diastolic
pressure (LVEDP). Subsequent to changes in heart rate and arterial pressure, isoproterenol also decreased rate pressure product.
Present study findings clearly demonstrate the detrimental outcome of isoproterenol induced-oxidative stress on cardiac function
and tissue antioxidant defense and substantiate its suitability as an animal model for the evaluation of cardioprotective
agents. 相似文献

The present paper focuses on assessing the levels of various enzymatic and non-enzymatic antioxidants in selected berries
of Indian sub-continent viz., gooseberry, grapes, orange and tomato. This study has revealed that orange, tomato and grapes
possess predominant quantities of enzymatic antioxidants namely SOD, catalase and glutathione peroxidase respectively. The
levels of antioxidants analyzed namely reduced glutathione, vitamin C and vitamin A were maximal in grapes, orange and tomato
respectively. All the extracts of berries included in the present study inhibited iron inducedin vitro lipid peroxidation in erythrocytes, the extend of inhibition being highest for gooseberry and orange compared to tomato and
grapes which could be attributed to their in-built antioxidant system. 相似文献

A glutathione redox cycle is a major antioxidant defense system for the detoxification of reactive oxygen species within erythrocytes.
Reactive oxygen species such as superoxide anions, hydrogen peroxide and hydroxyl radicals are generated as a host defense
mechanism for killing of engulfed Leishmania donovani, a causative agent of visceral leishmaniasis, are capable of damaging
lipids and other biomolecules when produced in excess. Erythrocytes are most vulnerable to Reactive oxygen species. In present
study we aimed to evaluate erythrocyte reduced glutathione (GSH) levels as an antioxidant and erythrocyte malondialdehyde
(MDA) as a marker of lipid peroxidation. The study included twenty-five Visceral leishmaniasis patients and they were followed
up after their complete chemotherapy with antileishmanial drugs (sodium stibogluconate) for 30 days. Forty six age and sex
matched healthy individuals were taken as controls. GSH levels in erythrocytes of visceral leishmaniasis patients were increased
in spite of significant increased erythrocyte MDA as compared to controls. Whereas erythrocyte GSH and MDA levels of follow
up patients were decreased as compared to patients before treatment groups. We concluded that visceral leishmaniasis patients
are in oxidative stress which most likely induces the endogenous antioxidant such as GSH or its poor utilization by cells. 相似文献

Effect of oral administration of 200 mg/Kg body weight of the aqueous extract ofOcimum sanctum (Tulsi) mixed with diet for eight weeks to diabetic (streptozotocin induced) rats was studied. There was significant reduction
in fasting blood glucose, serum lipid profile, lipid peroxidation products, (LPO) and improvement in glucose tolerance. The
aqueous extract also decreased LPO formation (thiobarbituric acid reactive substances TBARS) and increased antioxidant enzymes
superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione transferase (GT) and one antioxidant
reduced glutathione (GSH) in plasma and rat liver, lung, kidney and brain. The decrease in TBARS and increase in GSH, SOD,
CAT, GPX, and GT clearly shows the antioxidant property ofOcimum sanctum. 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

In this communication, we show the modulatory potential of papaverine, an opium alkaloid and a well known vasodilator agent
on the ethanol-induced hepatic oxidative stress in male Wistar rats. Ethanol treatment (50% v/v) enhanced lipid peroxidation
significantly accompanied by a decline in the activities of glutathione peroxidase (G-Px), glutathione reductase (GR) and
depletion in levels of hepatic glutathione (GSH). Ethanol administration increased hepatic glutathione-s-transferases (GST).
Enhanced lipid peroxidation induced by ethanol was significantly reduced when papverine was coadministered (P<0.05). In addition,
the depleted levels of glutathione and inhibited activities of G-Px and GR recovered significantly (P<0.05) levelling off
to control values on co-exposure. Papaverine (200 mg/kg bw) effectively antagonised the ethanol-induced lipid peroxidation
and impaired glutathione levels and glutathione dependent enzyme systems. Our results suggest that papaverine is an effective
chemopreventive agent in the liver and may suppress the ethanol-induced hepatotoxicity. 相似文献

BackgroundDiabetes is a metabolic disorder caused by defects in insulin production and activity. During disease progression, changes in lipid peroxidation cause structural modifications via production of free radicals. Fangchinoline is a well-known alkaloid present in Stephaniae tetrandrine S. Moore, which has demonstrated antioxidant, anticancer, and anti-inflammatory activities.ResultsThe present study analyzed the anti-diabetic and antioxidant effects of fangchinoline in male rats with streptozotocin-induced diabetes. Rats were divided into the following groups: normal control, diabetic, diabetic + fangchinoline 100 mg/kg, diabetic + fangchinoline 200 mg/kg and diabetic + glibenclamide 600 µg/kg. The treatment was administered orally for 45 consecutive days. Lipid peroxidation was substantially increased by >50% in the serum, as well as the liver, kidney, and heart tissues of diabetic rats. However, fangchinoline supplementation significantly reduced lipid peroxidation to near normal levels. Reactive oxygen species levels were substantially increased by >500% in the serum, as well as the liver, kidney, and heart tissues of diabetic rats. Fangchinoline supplementation reduced reactive oxygen species to near normal levels. Fangchinoline supplementation significantly improved superoxide dismutase, glutathione peroxidase, catalase, and reduced glutathione levels in diabetic rats. Total hexoses, sialic acid, hexosamines, and fucose were increased in diabetic rats, whereas fangchinoline supplementation significantly reduced these total hexoses, sialic acid, hexosamines, and fucose to near normal levelsConclusionsSupplementation with fangchinoline led to significant attenuation of the levels of lipid peroxidation, ROS, and glycoprotein components such as total hexoses, hexosamines, sialic acid, and fucose, while improving antioxidant marker levels.How to cite: Xia J, Huang W, Zhou F.

The aim of this study was to evaluate the radioprotective effect of turmeric extract (40 mg/kg body weight) and vitamin E
(α- tocopherol acetate, 400 IU/kg body weight) supplementation on lipid peroxidation, reduced glutathione and antioxidant
defense enzymes in various organs like liver, kidney and salivary glands at 24 h in adult Swiss mice. 131Iodine exposure significantly increased lipid peroxidation in kidney and salivary glands in comparison to control animals.
Pre supplementation with turmeric extract for 15 days showed significant lowering of lipid peroxidation in kidney. On the
other hand vitamin E pre supplementation showed marked reduction in lipid peroxidation in salivary glands. Reduced glutathione
levels decreased significantly in liver after radiation exposure. However, pre supplementation with turmeric extract and vitamin
E did not improve glutathione levels in liver. In conclusion, we have observed differential radioprotective effect of turmeric
extract and vitamin E in kidney and salivary glands. However, Vitamin E seems to offer better radioprotection for salivary
glands which is known to be the major site of cellular destruction after radioiodine therapy in patients. 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

The study was undertaken to evaluate the possible involvement of oxidative stress in the pathogenesis of ethanol induced testicular
atrophy in rats. Adult male rats were orally administered ethanol at a dose of 1.6 g/kg body weight/day for four weeks. Twenty-four
hours after the last treatment the rats were sacrificed using anesthetic ether. Testes were removed and weighed. Apoptosis
was studied by using the Feulgen reaction on 5 μ thin paraffin sections of testis. Testicular homogenate was prepared and
centrifuged. The supernatant was used for the estimation of extent of lipid peroxidation and antioxidant defense status. There
was significant reduction in body weight: and in testicular weight and diameter in ethanol treated rats. Extent of germ cell
apoptosis was significantly high in ethanol treated rats. Ethanol treated rats showed significantly high tissue TBARS level
and glutathione S-transferase activity; and low tissue ascorbic acid, reduced glutathione, superoxide dismutase, catalase,
glutathione peroxidase and glutathione reductase activities. Chronic ethanol administration resulted in high oxidative stress
in the testes either due to increased extent of lipid peroxidation or due to decreased antioxidant defenses, and thereby induces
germ cell apoptosis leading to testicular atrophy. 相似文献

The effect of Emblica officinalis fruit extract (EFE) against alcohol-induced hepatic damage in rats was investigated in the present study. In vitro studies showed that EFE possesses antioxidant as well nitric oxide (NO) scavenging activity. In vivo administration of alcohol (5 g/kg b.wt/day) for 60 days resulted increased liver lipid peroxidation, protein carbonyls, nitrite plus nitrate levels. Alcohol administration also significantly lowers the activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione S-transferase and reduced glutathione as compared with control rats. Administration of EFE (250 mg/kg body weight) to alcoholic rats significantly brought the plasma enzymes towards near normal level and also significantly reduced the levels of lipid peroxidation, protein carbonyls and restored the enzymic and non-enzymatic antioxidants level. This observation was supplemented by histopathological examination in liver. Our data indicate that the tannoid, flavonoid and NO scavenging compounds present in EFE may offer protection against free radical mediated oxidative stress in rat hepatocytes of animals with alcohol-induced liver injury. 相似文献

The study was designed to find out the correlation between lipid peroxidation, lipoprotein levels to severity and complication
of diabetes mellitus. Degree of lipid peroxidation was measured in terms of malondialdehyde (MDA) along with lipid profile
and blood glucose in diabetes mellitus. It is categorised into insulin dependent diabetes mellitus (IDDM), non insulin dependent
diabetes mellitus (NIDDM) and diabetes mellitus(DM) with complication.
Total 112 known diabetic patients and 52 non-diabetic controls were studied. These patients were grouped as per the concentration
of fasting blood glucose level i.e. controlled, poorly controlled, and uncontrolled group. There are significant increase
in the lipid peroxide (MDA) and lipid profile except HDL cholesterol which is decreased, has been found in all groups as compared
to controls In NIDDM group lipid peroxidation was markedly increased than IDDM group and it was higher in DM with complications.
Other finding observed was that the level of lipid peroxide increased as per the increase in concentration of blood glucose.
The increase lipid peroxidation in the hyperglycemic condition may be explained, as the superoxide dismutase enzyme which
is antioxidant becomes inactive due the formation of superoxide radical within the cell. Maximum lipid peroxidation leads
to the damage of the tissue and organs which results into complication in diabetic patients. High levels of total cholesterol
appear due to increased cholesterol synthesis. The triglyceride levels changes according to the glycemic, control. The increase
may be due to overproduction of VLDL-TG.
It is concluded that good metabolic control of hyperglycemia will prevent in alteration in peroxidation and the lipid metabolism,
which may help in good prognosis and preventing manifestation of vascular and secondary complication in diabetes mellitus. 相似文献

Liver transplantation is an accepted therapy for chronic liver disease patients. These patients generally have low levels
of fat soluble vitamins, which have important antioxidant roles. Therefore, this study was undertaken to investigate whether
such patients had evidence of antioxidant depletion and increased lipid peroxidation before transplant and whether the subsequent
ischemia and reperfusion encountered during liver transplantation have any effect on antioxidant levels and lipid peroxidation.
We assessed plasma total antioxidant capacity and serum lipid peroxide in 12 patients undergoing liver transplantation and
equal numbers of healthy subjects. We found that before reperfusion, antioxidant levels were significantly decreased along
with significantly elevated lipid peroxidation levels as compared with healthy controls (P<0.001). On reperfusion of the liver
graft, further declined values of total antioxidant accompanied with highly elevated lipid peroxidation were seen than those
of pre-reperfusion samples (P<0.001). This data shows that patients undergoing liver transplant have lowered antioxidant defenses
and evidence of free radical damage, which compound the additional insult of reperfusion injury. Therefore antioxidant therapy
in these patients before transplantation may ameliorate the effects of reperfusion. 相似文献

A total of 41 healthy male pesticide sprayers exposed to different clases of pesticides for 3-5 years were compared with 21
controls matched for age and economic status with respect to free radical generation, lipid peroxidation, antioxidant status,
cholesterol, lipoprotein status and haematological profile. Plasma lipid peroxidation was estimated in the form of thiobarbituric
acid reactive substances (TBARS) produced. Significant increase in TBARS was observed in sprayers population when compared
with control subjects and the level of TBARS increased with increase in the duration of exposure. The levels of antioxidants
such as glutathione (GSH) were significantly depleted, whereas those of superoxide dismutase (SOD) were remarkably increased
than control population. Significant reduction in total cholesetrol, alteration in lipoprotein fractions and nonsignificant
changes in hematological parameters were observed. These results suggested that exposure to pesticidal residual drift augments
the free radical generation, and lipid peroxidation. Decline in non-enzymatic antioxidant and elevation of enzymatic antioxidant
were observed. Supplementation of α-tocopherol for 45 days resulted in the partial restoration of these biochemical changes
produced by pesticides. 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
