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

This study was undertaken to evaluate the levels of plasma magnesium, lipid peroxides, nitric oxide end products, erythrocyte
membrane lipid peroxides, erythrocyte reduced glutathione and erythrocyte superoxide dismutase activity in type-2 diabetes
mellitus patients. 60 patients with type-2 diabetes mellitus and 30 healthy control subjects were included in this study.
Among 60 type-2 diabetic patients, 30 patients were without complication and 30 patients were with various complications.
Decreased levels of plasma magnesium, erythrocyte reduced glutathione and erythrocyte superoxide dismutase activity while
increased levels of plasma lipid peroxides, nitric oxide end products and erythrocyte membrane lipid peroxides were observed
in patients with type-2 diabetes mellitus. We propose that, under the shadow of hypomagnesaemia, there is excessive production
of reactive oxygen species and reactive nitrogen species as reflected by elevated lipid peroxides and nitric oxide end products
concomitant with dwindled antioxidants and suggest their association with late complications in type-2 diabetes mellitus. 相似文献

Plasma levels of lipids, lipoproteins and lipid peroxides and erythrocyte Na+−K+ ATPase, Mg2+ATPase and antioxidant enzymes were measured in type-2 diabetic patients. A significant decrease in Na+-K+-ATPase activity was observed in diabetic patients which was negatively correlated with blood glucose and lipid peroxides,
while the Mg2+-ATPase activity was increased. In the diabetic subjects the plasma concentrations of Na+ and K+ were increased where as erythrocyte levels of Na+ were increased and K+ were decreased. Hyperlipidaemia and increased levels of lipid peroxides were observed in the diabetic subjects. There was
a significant increase in erythrocyte catalase activity in diabetics which positively correlated with their lipid peroxides.
There was no change in GPx activities between controls and diabetics. 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

Crystal aggregation and retention are critical events for the formation of kidney stones. There is a close association between
crystal development and free radical activity in vivo. In the present study 30 subjects presenting with urolithiasis were
included. Serum levels of total lipid peroxides, nitric oxide (as nitrite), α-tocopherol, plasma ascorbic acid (vitamin C)
and erythrocyte superoxide dismutase activity were measured. These findings were compared with 30 age matched control subjects
irrespective of sex. Student's ‘t’ test was applied for statistical analysis. There was a significant increase in lipid peroxides
(p<0.001), where as significant decrease in nitrite (p<0.01) and α-tocopherol (p<0.001) levels were observed. Plasma ascorbate
(p>0.05) and erythrocyte superoxide dismutase activity (p>0.05) was also found to be decreased but the difference was not
statistically significant which suggests that oxidative stress is evident in urolithiasis with depletion in antioxidant status
where as decrease in nitric oxide may be less abetting in disease condition. 相似文献

Nephrotic syndrome is the common chronic disorder characterized by alteration of permeability of the glomerular capillary
wall, resulting in its inability to restrict the urinary loss of proteins. Nephrotic syndrome is characterized by heavy proteinuria,
hypoalbuminemia, hyperlipidemia associated with peripheral edema. The molecular basis of glomerular permselectivity remains
largely unknown. In recent years it has been proposed that Nephrotic syndrome is a consequence of an imbalance between oxidant
and antioxidant activity. The present study was aimed to test that the reactive oxygen species are the mediators of excessive
protein permeability and other complications of Nephrotic syndrome. For this 30 adults with Nephrotic syndrome were studied.
The control group comprised 30 healthy adults matched for age. Serum levels of lipid peroxides, nitric oxide (NO⊙), α- tocopherol,
ascorbic acid, erythrocyte superoxide dismutase activity, serum albumin, uric acid, cholesterol and plasma total antioxidant
capacity were measured. Student’s ‘t’ test was applied for statistical analysis. There was a significant increase in lipid
peroxide (1.58 ± 0.42 in controls, 3.64 ±1.3 in patients) (P<0.001) levels in study group as compared with controls. α-tocopherol
(12.95 ± 1.04 in controls, 9.93 ± 1.43 in patients) (P<0.001), erythrocyte SOD activity(1.88 ± 0.9 in controls 1.07 ± 0.5
in patients) (P=0.01), serum albumin(4.06 ± 0.50 in controls, 3.04 ± 0.11 in patients) (P<0.001), and plasma total antioxidant
capacity (847.33 ± 126.83 in controls, 684.00±102.94 in patients) (P<0.001) were significantly decreased. There was non-significant
increase in uric acid (P>0.05), a non-significant decrease in NO⊙ (38.48 ± 15.47 in controls 37.47 ± 14.27 in patients) (P>0.05)
and ascorbic acid levels ascorbic acid,( 0.95 ± 0.31in controls 0.79 ± 0.30 in patients) (P>0.05) in study group as compared
with controls. Imbalance between oxidants and antioxidants may contribute to pathogenesis of proteinuria and related complications
in nephrotic syndrome. 相似文献

The present study was undertaken to evaluate the levels of serum lipid peroxide, nitric oxide end poducts, erythrocytic superoxide
dismutase activity and serum α
1-antitrypsin in smokers. Total 90 active cigarette smokers were subdivided into Group I (subjects with smoking habit of less
than 10 cigarettes per day) and Group II (with smoking habit of more than 10 cigarettes per day). In both groups lipid peroxide
and nitric oxide end products were significantly increased with significantly decrease in erythrocytic superoxide dismutase
activity and serum α
1-antitrypsin as compared to controls. Our findings show enhanced oxidative stress and reduced α
1-antitrypsin in cigarette smokers. Further increase in number of cigarettes per day exacerbates the oxidative stress with
decrease in α
1-antitrypsin. 相似文献

Increased oxidative stress is a widely accepted participant in the development and progression of diabetes and its complications.
The present study has been undertaken to evaluate oxidative stress in type 2 diabetes mellitus and effect of vitamin E supplementation
on oxidative stress. In all 120 subjects were enrolled in the present study, 40 subjects are age and sex matched controls.
Test group comprised of clinically diagnosed (n = 80) type 2 diabetic patients. Biochemical parameters like serum MDA, nitric oxide, superoxide dismutase, erythrocyte reduced
glutathione and platelet aggregation were analyzed in control and diabetic group. Test group is further categorized as Group
I (n = 40) diabetics were treated by only hypoglycemic drugs and Group II (n = 40) diabetics were treated by hypoglycemic drugs with vitamin E supplementation. All above biochemical parameters were
again reassessed after 3 months follow-up in both group and its values were compared with its respective baseline levels.
The study shows, reduction of oxidative stress, improvement in antioxidant enzymes and endothelial dysfunction in group II,
those were on treatment of hypoglycemic drugs along with vitamin E supplementation. Hence the present study may conclude that
vitamin E supplementation along with hypoglycemic drugs may be beneficial to type 2 DM patients to minimize vascular complications. 相似文献

The association of serum antioxidatns and lipids was studied in 350 urban individuals with an age range of 40–76 years, in comparison with a control rural sample of equal size. Glutathione Peroxidase (GPx) activity was found to be significantly higher in urban population when compared to rural population. Urban population were characterised by elevated levels of serum cholesterol (SC), low density lipoprotein cholesterol (LDLC) and triglycerides (TG) in comparison with rural population. In urban females both tocopherol (T) and GPx were negatively related with age. The serum lipid levels were found to be increased with age in urban population when compared to rural population. Further the correlation coefficients revealed that LDLC positively (.285:P<.05), and TG inversely (?.512:P<.05) related to ascorbic acid (AA), and an inverse association of SC (?.625:P<.05), high density lipoprotein cholesterol (HDLC) (?.369:P<.05) and LDLC (?.532:P<.05) with T in urban population. In rural population GPx shown a good positive correlation with lipid levels. The results of this study revealed that accumulation of lipids with unaltered antioxidants may be the consequence of urbanization. 相似文献

Thiamine or vitamin B1 is a well known coenzyme and nutrient necessary for the assembly and right functioning of several enzymes involved in the energy metabolism. The present study evaluates oxidative stress and prevalence of neurodegenerative conditions in the brain following TD. The study was carried out on mice (Musmusculus) in three groups, namely control and thiamine-deficient group for 8 (TD 8) and 10 (TD 10) days. Lipid peroxidation was determined in terms of reduced glutathione (GSH) and thiobarbituric acid reactive substance (TBARS). The level of antioxidant enzymes such as catalase (CAT), glutathione reductase, glutathione peroxidase (GPx), superoxide dismutase (SOD) and glutathione transferase (GST) were measured along with histopathological studies in all the groups. There was significant increase in the TBARS levels in group II (TD 8) and group III (TD 10) animals in comparison to controls (Group I). The GSH levels were found to be lower in both the treated groups. The level of antioxidant enzymes CAT (p < 0.001), glutathione reductase (p < 0.001), GPx (p < 0.001), SOD (p < 0.0001) were found to be significantly reduced in group III (TD 10) in comparison to controls. Histopathological studies showed moderated to extensive neuronal loss in group II and group III in comparison to control group. The increase in LPO and reduction in enzymes CAT, glutathione reductase, GPx, SOD, and GST following TD suggests mitochondrial dysfunction, neuronal loss acute oxidative stress that may impair the functioning of the brain along with the rise of neurodegenerative conditions in the affected animals. 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

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

Erythrocyte aldehyde dehydrogenase (ALDH) activity in a normal reference population from North India was determined from results
of 22 healthy subjects (12 male and 10 female). We compared these data with results of 19 alcoholic patients (13 male and
6 female). The mean erythrocyte ALDH activity of male and female alcohol abusers was 16.2% and 20.9% lower than the mean values
for healthy subjects, respectively (P<0.001 and <0.01). It is proposed that erythrocyte ALDH activity may be a useful clinical
chemical marker of alcohol abuse and alcoholism. 相似文献

Oxidative stress plays an important role in the development of malarial anemia. The present study was undertaken to study
the role of oxidant and antioxidants in the patients ofPlasmodium falciparum malaria (n=25),Plasmodium vivax malaria (n=25) as against the normal control subjects (n=25). The parameters included are the hematological [hemoglobin,
erythrocyte adenosine deaminase (ADA) activity, ADP-induced platelet aggregation] and serum total lipid peroxide as an index
of oxidative stress and antioxidants [erythrocytic superoxide dismutase (SOD) activity, serum vitamin E] & serum iron.
Significant alterations in all above parameters were noted in both groups of malaria patients as compared to control subjects.
Maximum significant alterations in hematological parameters were noticed inP. falciparum infection as compared toP. vivax malaria (p<0.001). Substantial rise in serum total lipid peroxides and a significant reduction in antioxidants such as serum
vitamin E and serum iron were noted inP. falciparum malaria as compared toP. vivax malaria (p<0.001), whereas maximum decline in erythrocytic SOD activity was observed inP. vivax infection as compared toP. falciparum malaria (p<0.05). Follow-up examination revealed the restoration of the levels of all biochemical parameters to the normal
level after 20 days of antimalarial therapy.
The study specified severity ofP. falciparum malaria and also functional duality of oxidant. 相似文献

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

The present study was carried out to explore the altered lipid, lipoprotein and apoprotein abnormalities along with lipoprotein
(a) in chronic kidney disease patients with stage I to V which were further divided into group 1 (stage I and II), group 2
(stage III and IV) and group 3 (stage V). 50 chronic kidney disease patients with stage I to V and 20 healthy normal subjects
as controls were recruited for this study. Among the various parameters tested triglyceride levels were high in group 1 and
2, whereas VLDL cholesterol, Lp (a) and apo B levels were significantly high in all the groups when compared to controls (P<0.05).
However, LDL cholesterol level was significantly low in group 3 only as compared to control group (P<0.05). Apoprotein AI
values also showed significant decrease in all groups as compared to controls (P<0.05). Though total cholesterol levels in
group 1 and LDL levels in group 1 and 2 were higher than controls, but the values attained not statistically significant (P>0.05).
In conclusion high levels of VLDL cholesterol, Lp (a), apo B and low levels of apoprotein AI as reported in this study are
the major lipid disorders in the development of cardiovascular complications at all the stages in these patients. 相似文献

Presence of oxidative stress in type 2 diabetes mellitus (DM) is well proved. Current study was undertaken to know the relation
between fasting plasma glucose (FPG) and copper along with antioxidants like total thiols and ceruloplasmin, and antioxidant
enzyme glutathione S transferase (GST). The study group consisted of a total of 201 subjects which included nondiabetic healthy
control subjects (n = 78) and diabetic patients (n = 123). Plasma total thiols, GST, copper and ceruloplasmin levels were
measured all the subjects using spectrophotometric methods and FPG levels were determined in clinical chemistry analyzer Hitachi
912. There was significant increase in FPG (P<0.001) and copper (P<0.001) and decrease in ceruloplasmin (P<0.001) and protein
thiols (P<0.001) in type 2 DM cases compared to healthy controls. There was no significant change in GST between type 2 DM
cases and controls. There was significant negative correlation of FPG with antioxidants like ceruloplasmin (r = −0.420, P<0.001)
and total thiols (r = −0.565, P<0.001). Protein thiols correlated positively with ceruloplasmin (r = 0.364, P<0.001). Our
study indicates possible increase in copper mediated generation of ROS leading to increased consumption of available antioxidants
in the body. 相似文献

The present study was undertaken in 100 subjects, 30 diabetics without complication (group I), 40 diabetics with retinopathy
(group II) and 30 non diabetic as normal control group (group III). Blood sugar levels, magnesium, cholesterol and triglyceride
were analyzed from plasma and serum. The results were correlated with degree of diabetic control from the levels of glycosylated
hemoglobin. Serum magnesium levels in group II were found to be significantly lowered than in group I. There was also significant
difference in magnesium levels of group I and group III. We found a significant correlation between the glycosylated hemoglobin
and magnesium levels in our study.
The results also indicate that the patients with diabetic retinopathy showed significant rise in serum cholesterol and triglyceride.
Probably hypomagnesemia and increased serum cholesterol and triglyceride levels are responsible for microvascular changes
in diabetes leading to retinopathy. The purpose of this study was thus to gather information about the degree of control of
diabetes and magnesium status. 相似文献

This study deals with the effects of freeze dried rhizome powder of Curcuma longa (C. longa) dissolved in milk on normal as
well as diabetic models. Diabetes of type II and type I was within 3 days of a single administration of doses of 45 and 65
mg kg−1 of streptozotocin respectively. Various parameters such as blood glucose levels, triglycerides, total cholesterol, high density
lipoprotein, very low density lipoprotein, low density lipoprotein, serum glutamic oxaloacetic transaminase, serum glutamic
pyruvate transaminase, alkaline phosphatase, creatinine, hemoglobin, urine protein and urine sugar in addition to body weight
were taken in to consideration and were analyzed after administration of variable doses of rhizome powder. The dose of 200
mg kg−1 was identified as the most effective dose as it increased HDL, Hb and bw (P<0.05) with significant decrease in the levels
of blood glucose, lipid profile and hepatoprotective enzymes (P<0.001). 相似文献

Erythrocyte membrane protein glycosylation increase by 3.4 fold in diabetes. Insulin or sulfonylurea treatment did not reduce
the extent of glycosylation. The serum protein glycosylation was comparable in all the groups including control. Erythrocyte
membrane Na+,K+-ATPase activity decreased in the diabetics; only insulin treatment partly restored the activity. Erythrocyte membrane acetylcholinesterase
activity decreased only in the sulfonylurea treated group. Serum butyrylcholinesterase activity was relatively low in the
diabetic and insulin treated diabetic groups. The Km and Vmax of the two components of Na+,K+-ATPase from erythrocyte membranes were differently affected in the diabetic and the two treatment groups. The Vmax of acetylcholinesterase
decreased only in the sulfonylurea treated group. Diabetic states resulted in decreased Vmax of components I and II of serum
butyrylcholinesterase. In insulin-treated diabetics, component II was absent. Sulfonylurea group resembled diabetics.In vitro incubation with insulin differentially affected the Na+,K+-ATPase and serum butyrylcholinesterase activities. 相似文献
