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

Hemodialysis represents a chronic stress status for its recipients. Many hypotheses state that this may be associated with
oxidative stress. Thus, there may be deficiency of antioxidants like erythrocytic superoxide dismutase, catalase, vitamin
E or increased generation of free radicals like superoxide anions. A study was carried out to investigate oxidant and antioxidant
status in chronic renal failure patients undergoing hemodialysis and effect of vitamin E supplementation on these two status.
Blood samples were collected from patients before and after hemodialysis and from controls. The samples were analyzed for
quantitation of MDA as index of lipid peroxide, nitric oxide, vitamin E, vitamin C and enzymatic antioxidants namely erythrocyte
SOD and catalase. As compared to controls, the levels of serum MDA were significantly increased and activities of erythrocyte
SOD and catalase, levels of serum nitric oxide, serum vitamin E and plasma vitamin C were significantly decreased both before
and after hemodialysis. The efficiency of vitamin E therapy in hemodialysis patients was assessed by re-evaluating oxidant
and antioxidant status of same patients after supplementation of vitamin E. Vitamin E supplementation caused decrease in serum
MDA and increase in levels of serum nitric oxide, vitamin E, vitamin C and activities of erythrocytic SOD and catalase. Our
results suggest the presence of oxidative stress and the possible preventive role of vitamin E therapy in hemodialysis patients. 相似文献

The changes in the erythrocyte lipid peroxidation products (MDA), levels of glutathione (GSH), ascorbic acid and plasma vitamin
E (non enzymatic antioxidant parameters) and activities of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase
(GPX), catalase in erythrocytes and plasma glutathione - S - transferase (GST) activity were estimated in patients with rheumatoid
arthritis. This work was undertaken to assess oxidative stress and anti oxidant status in patients with rheumatoid arthritis.
It was observed that there was a significant increase in erythrocyte MDA levels, activities of SOD, GPX, plasma GST and a significant decrease in erythrocyte GSH, ascorbic acid, plasma vitamin E levels and catalse activity in
patients with rheumatoid arthritis when compared to controls. The results of our study suggests higher oxygen free radical
production, evidenced by increased MDA and decreased GSH, ascorbic acid, vitamin E and Catalase activity, support to the oxidative
stress in rheumatoid arthritis. The increased activities of antioxidant enzymes may be a compensatory regulation in response
to increased oxidative stress. 相似文献

The study was conducted to find out the extent of lipid peroxidation and antioxidant status in ischemic stroke patients (ISPs)
with and without diabetes. Malondialdehyde (MDA) was studied as a marker of lipid peroxidation. Glutathione (GSH), uric acid
and ceruloplasmin were estimated to study the antioxidant potential of ISPs. Significantly higher levels of MDA were found
in both the groups of ISPs and the increase in MDA was more in ISPs without diabetes. GSH levels were decreased significantly
in both the groups of ISPs and maximum decline was found in ISPs with diabetes. Uric acid levels were significantly increased
in both the groups of ISPs. Ceruloplasmin levels were increased significantly in ISPs without diabetes, whereas its levels
were slightly decreased in ISPs with diabetes. A negative correlation was found between MDA and the antioxidants GSH, uric
acid and ceruloplasmin in ISPs with diabetes. This study suggests that there is an association between ischemic stroke and
increased oxidative stress and the antioxidant potential is impaired in both the groups of ISPs with and without diabetes. 相似文献

This work was undertaken to investigate correlation between oxidative stress and initiation of pathogenesis of pregnancy induced
hypertension (PIH). Fifty primigravidae in age group of 20–35 years and gestational age 28–42 weeks with PIH were taken as
cases. Twenty healthy primigravidae with no medical and surgical complications of pregnancy and with blood pressure ≤140/90
mm Hg served as controls. The cases were again subgrouped as severe preeclampsia (12 in number) and mild pre-eclampsia (38
in number). All of them were evaluated for serum malondialdehyde (MDA), Serum vitamin E and plasma vitamin C levels. The serum
MDA levels were raised significantly in women with mild preeclampsia (P<0.01) and in women with severe preeclampsia (P<0.01)
in comparison to normal primi gravida. The serum vitamin E levels were decreased in primi gravida with mild preeclampsia (p<0.1)
and in primi with severe pre eclampsia (P<0.1) in comparison to normal primi gravida but the fall was not statistically significant.
There was a significant fall (P<0.05) in the vitamin C levels in primi with mild preeclampsia than in the normal primi. The
vitamin C levels in severe preeclamptic patients were lower than the normal primi but the fall was not statistically significant
(P=0.10). The serum MDA and vitamin E showed a negative correlation in all the cases. The serum MDA and plasma vitamin C also
showed a negative correlation in the control and study group. This observation suggests that in hypertensive disorders of
pregnancy there is an imbalance between lipid peroxidation and antioxidant vitamin status because of oxidative stress. The
decreased serum concentrations of the antioxidant vitamins supports the hypothesis that lipid peroxidation is an important
causative factor in the pathogenesis of preeclampsia. The rise in antioxidants is probably to compensate the increased peroxide
load in severe preeclampsia. 相似文献

This study aimed to correlate the oxidative stress marker levels in saliva with the clinical stage based on mouth opening, fibrotic bands and histopathological grades of oral submucous fibrosis (OSF) patients. The study included patients clinically diagnosed with OSF (n = 63) and equal number of age and gender matched controls. Patients with OSF were defined by mouth opening stage, fibrotic bands and histopathological grades. Unstimulated saliva from both control and OSF patients were analysed for oxidative markers like lipid peroxides (LPO), non-enzymic antioxidants [reduced glutathione (GSH), vitamin A, vitamin E, vitamin C] and enzymatic antioxidants [glutathione peroxidase (GPx), superoxide dismutase (SOD)] and correlated with different stages and grades. Total salivary protein and LPO were significantly increased in OSF group with no significant change in the levels of GSH compared to controls. In OSF patients, a significant decrease in the levels of vitamins A, C and E was observed. The activities of salivary SOD and GPx were significantly decreased in OSF patients compared to controls. These changes significantly correlated with the increasing and differing grades of OSF that reflects increased oxidative stress with the progress of OSF. 相似文献

In the present study, the role of serum lipid peroxide and serum nitric oxide as oxidants and erythrocytic superoxide dismutase
& serum vitamin E as antioxidants were determined in the 50 neonates with hypoxic ischaemic encephalopathy. (HIE) as against
25 healthy neonates as controls 50 patients of HIE were further divided into two groups i. e. mild and moderate HIE patients.
All subjects were in the age group of 37–41 weeks of gestation. The levels of serum lipid peroxide, serum nitric oxide and
erythrocytic superoxide dismutase were significantly elevated in both groups of neonates with HIE than those of controls (P<0.001),
whereas serum vitamin E levels were significantly decreased in both groups of HIE patients than those of controls (P<0.001).
A positive correlation was obtained between serum lipid peroxide and erythrocytic superoxide dismutase (r=+0.86). Alterations
in the status of oxidants and antioxidants indicate role of free radicals in the development of HIE. 相似文献

Oxidative stress was studied by estimating plasma levels of malondialdehyde (MDA), beta carotene, vitamin E and erythrocytic
superoxide dismutase(E-SOD) activity in 50 cases of carcinoma of upper digestive tract which included carcinoma of oral cavity,
pharynx and oesophagus. While plasma MDA level was found to be increased (3.5±1.0 nmole/ml), a significant decrease in beta
carotene (81.2±14.5mg%), vitamin E (8.5±1.1 mg/L) level and E-SOD activity (657.0±80.6 U/G Hb) were observed in carcinoma
of upper digestive tract. Patients were treated with radiotherapy which itself was toxic enough and produced its deleterious
effects by generation of reactive oxygen species (ROS). As antioxdiants can detoxify ROS, beneficial effect if any, of antioxidant
administration during radiotherapy was studied in two groups of patients, group A (n=5, supplemented with antioxidants) and
group B (n=5, without antioxidant supplementation). Plasma MDA level was found to be elevated in both the groups but the increase
in group B was significant, compared to pretreatment level. Further, body weight was found to be significantly decreased in
group B patients, which was maintained in group A patients. Moreover, group A patients showed significant elevation in beta
carotene concentration, thus showing beneficial effect of administration of antioxidants during radiotherapy without disturbing
the desirable therapeutic effect of radiotherapy. 相似文献

Lipid peroxidation product, malonaldehyde (MDA) and antioxidants were estimated in plasma and erythrocytes of 34 cases of
oral submucous fibrosis (OSMF) of different grades with equal number of healthy controls to evaluate the association of reactive
oxygen species (ROS) and OSMF. While plasma MDA was found to be significantly higher in patients (3.3±0.4 nmole/ml, P<0.001)
as compared to controls (2.4±0.5 nmole/ml), plasma beta carotene and vitamin E levels were found to be decreased significantly
in patients (81.7±14.3 μg/100 ml, P<0.001; 9.3±0.9 mg/L, P<0.01 respectively) with respect to healthy controls (110±20.8 μg/100
ml and 10.1±1.2 mg/L). The decrease in beta-carotene and vitamin E was found to be more significant in OSMF grade II and III
than in grade I. After 6 weeks of oral administration of beta-carotene and vitamin E, patients showed increase in plasma level
of these two antioxidants along with decrease in MDA level associated with clinical improvement. 相似文献

Susceptibility of Schizophrenic patients to lipid peroxidation relative to healthy control subjects was investigated by measuring
the malondialdehyde (MDA) levels in plasma. The main finding was that Schizophrenic patients were more susceptible than control
subjects to oxidative damage as evident from increased MDA levels in plasma. Antioxidant levels are also depleted in Schizophrenic
patients when compared to normal subjects as evident from decreased levels of vitamins E and C in the plasma. Impaired antioxidant
defense and increased lipid peroxidation suggests that treatment with antioxidants (Vitamin E, Vitamin C, beta carotene) at
the initial stages of illness may prevent further oxidative injury and deterioration of associated neurological deficits in
Schizophrenia. 相似文献

An adequate antioxidant reserve which is usually present in a vegetarian diet is associated with higher life expectancy. On
the other hand habitual consumption of fish is associated with lower risk of cardiovascular diseases which is attributed to
the polyunsaturated fatty acids (PUFA) present in it. However the PUFA are readily susceptible to oxidation leading to the
formation of free radicals which is known to be involved in the causation of several diseases.
The oxidant-antioxidant status of 23 vegetarians and 22 fish eaters was studied by determining the plasma lipid peroxides
measured as malondialdehyde (MDA) and the antioxidants, viz. glutathione (GSH), ascorbic acid, ceruloplasmin and uric acid.
Results show that the ascorbic acid values were significantly higher in vegetarians. In addition, MDA correlated negatively
with ascorbic acid only in vegetarians. However, correlation of MDA with glutathione showed a significant negative correlation
only in fish eaters. There was no statistically significant difference in the MDA, GSH, ceruloplasmin and uric acid levels.
The mechanism behind these findings are not clear and needs to be explored. 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

Plasma vitamin E and malondialdehyde (MDA) concentrations were estimated in a group of 25 patients (17 males and 8 females) with head and neck cancer and the results were compared with a group of normal healthy controls. Plasma vitamin E levels were found to be significantly reduced while MDA levels were increased in patients than the controls. The fall in vitamin E was nearly same in all the patients studied irrespective of the site, TNM stage, histopathology and character of lesion. The levels did not vary immediately after radiotherapy but were significantly increased 3 months after the radiotherapy. These preliminary data suggest that the cancer patients have suboptimal vitamin E status which may be a contributory factor for increased lipid peroxidation in such cases. 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

Elevated free radical generation in inflamed joints and impaired antioxidant system has been implicated in rheumatoid arthritis
(RA). Green tea extracts (GTE) have been shown to reduce inflammation in inflammatory arthritis murine model. This study investigates
possible mechanisms by which vitamin C and GTE protect joints in RA rat model. This study included forty adult male rats that
were divided into four groups (10 rats each); control group, collagen II induced RA group (CII), CII treated with vitamin
C (CII + Vit C) and CII treated with GTE (CII + GTE) in physiology laboratory, Assiut University, Egypt. After 45 days of
treatment, plasma levels of lipid peroxides (LPO), nitric oxide (NO), ceruloplasmin (CP), superoxide dismutase (SOD), uric
acid (UA) and glutathione (GSH) were detected using colorimetric methods, PGE2 using ELISA and copper (Cu) and zinc (Zn) using spectrometer. In CII group, levels of LPO, NO, PGE2, UA, CP, Cu were higher while SOD, GSH, Zn were lower than controls. In groups treated with vitamin C and GTE, levels of
SOD, GSH were increased while levels of LPO, NO, PGE2, Cu, CP were decreased compared with CII group. Levels of UA were decreased and Zn increased in GTE treated group compared
with CII group. GTE treated group showed higher Zn and low Cu levels compared with vitamin C treated group. This study suggests
proper GTE and vitamin C intake may effectively normalize the impaired oxidant/antioxidant system and delaying complication
of RA. 相似文献

Preeclampsia is a multisystem disorder involves altered homeostasis of oxidants–antioxidants, inflammatory process and endothelial dysfunction. The present study aim was to determine the levels of oxidative stress parameters (malondialdehyde, protein carbonyl, ischemia modified albumin and xanthine oxidase), nutrient antioxidants (vitamin C and vitamin E), enzyme antioxidants (catalase, superoxide dismutase, glutathione peroxidase glutathione reductase), total antioxidant status (TAS) and its association with nitric oxide. The study population consists of three groups, non pregnants (Group 1, n = 57), normotensive pregnants (Group 2, n = 57) and Preeclampsia (Group 3, n = 57). Group 2 and 3 were followed after delivery within 48 h. In preeclampsia xanthine oxidase, malondialdehyde and uric acid levels were significantly increased (p < 0.001), while TAS decreased (p < 0.05) when compared to normotensive pregnant and non pregnant. Catalase, glutathione reductase levels were increased (p < 0.005) and vitamin E, super oxide dismutase levels were decreased (p < 0.001) in preeclampsia when compared to normal pregnants. Receiver operating characteristics curve analysis showed area under curve for xanthine oxidase (0.8), malondialdehyde (0.804), Uric acid (0.84), ischemia modified albumin (0.92) and catalase (0.88) which indicated as good markers in preeclampsia. Amongst, ischemia modified albumin is a better marker of intrauterine hypoxic reperfusion risk with sensitivity 87.7 % and specificity 91.2 %. The increased hydrogen peroxide from xanthine oxidase adds to oxidative stress and increased catalase activity in preeclampsia represents combating action. Increased oxidative stress, decreased TAS and its apparent reversible changes evinced within 48 h after delivery in preeclampsia illustrated that placental abnormality is the contributing factor in the pathogenesis. 相似文献

Evidence of increased oxidative stress in patients of osteoarthritis in comparison with healthy control subjects was investigated
by measuring the thiobarbituric acid reactive substances (TBARS), vitamin C, reduced glutathione (GSH) and the activities
of superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx) in erythrocytes. It was observed that osteoarthritis
patients were more susceptible to oxidative damage than controls as evident from increased TBARS and decreased ascorbic acid,
GSH, catalase and GPx in erythrocytes. Significant increase in SOD activity found in patients might be an adaptive response.
With the understanding of the role of antioxidants in arthritis, it is becoming increasingly clear that these agents seem
to be beneficial in osteoarthritis. 相似文献

The present study was undertaken to study the impact of surgical menopause on oxidant and antioxidant status in relation to estrogen levels after 3 months of surgery. Total 130 women who had undergone total hysterectomy (TH) with or without bilateral salpingo-oophorectomy (BSO) were included in this study. The oxidant status was assessed by measuring plasma levels of malondialdehyde and antioxidant status was assessed by measuring superoxide dismutase, catalase, glutathione, glutathione peroxidase, estrogen, and Vitamin A, E and C levels. The malondialdehyde level was significantly increased (p < 0.05) in all women who underwent TH with or without BSO. Significant increased levels of superoxide dismutase were observed in women who underwent TH with BSO. The blood glutathione levels were significantly decreased in women after TH only but significantly increased in women who had undergone TH with BSO. The levels of estrogen, vitamin E and vitamin C were significantly decreased in women who underwent TH with BSO. The catalase, GPx and vitamin A did not differ significantly in all groups. The result suggests that surgical menopause is associated with oxidative stress which reiterates the fact that ovaries retain some function even after menopause. 相似文献

Free radicals play an important role in the pathogenesis of tissue damage in many clinical disorders, including atherosclerosis.
Antioxidants protect the body from damage caused by free radicals. In this study we investigated oxidative stress, antioxidants
and inflammatory molecules in patients with acute myocardial infarction. This study has been carried out on 106 patients with
acute myocardial infarction, (89 men and 17 females). The control group consisted of 50 healthy, age-matched subjects (40
men and 10 females). Levels of Glucose, lipid profile, glutathione reduced, glutathione peroxidase, Superoxide dismutase,
Glycosylated hemoglobin, fibrinogen, vitamin C, vitamin E, malondialdehyde, ceruloplasmin, adenosine deaminase, lysozyme and
sialic acid were measured. Malondialdehyde and ceruloplasmin levels were significantly high and antioxidants such as vitamin
C, vitamin E, glutathione reduced, glutathione peroxidase and superoxide dismutase were significantly decreased in diabetic
and non-diabetic AMI patients as compared with control (p<0.001). Inflammatory markers showed significant rise in diabetic
patients as compared with controls. Our results clearly show increased inflammation and oxidative stress in patients with
acute myocardial infarction. Depression of antioxidant system in these patients confirms this conclusion. 相似文献

Generation of reactive oxygen species is an important factor in the development and maintenance of rheumatoid arthritis (RA)
in humans. This study was undertaken to investigate interplay among oxidants, antioxidants and pathogenesis of Rheumatoid
arthritis. Serum levels of lipid peroxides, nitric oxide, vitamin E and ratio of calcium/phosphorus in RA patients were determined
and compared with normal healthy controls. Significant increases in lipid peroxides (p<0.001) and nitric oxide (p<0.001) levels
were found in patients presenting with RA as compared to controls. Whereas significant decrease in vitamin E (P<0.001) and
calcium/phosphorus ratio (p<0.001) were found in Rheumatoid arthritis patients as compared to controls. Positive correlation
was found between lipid peroxides and nitric oxide as well as between vitamin E and calcium. While lipid peroxides and nitric
oxide were correlated negatively with vitamin E. whereas negative correlation was observed between MDA and Calcium/Phosphorus
ratio in patients with rheumatoid arthritis. Our findings suggest that there is a close association between bone loss and
oxidative threat in patients presenting with Rheumatoid arthritis. 相似文献
