The present study was carried out to assess the biochemical profile and outcome of pregnancy and study the adverse consequences
if any, among normal and high risk pregnant women. The study group included 182 normal and 168 high risk cases attending to
private and Government Hospitals in Bangalore. The high risk groups were: Pregnancy induced hypertension (PIH), gestational
diabetes mellitus (GDM), Adolescents and anemic cases. Lipid peroxidation was enhanced in PIH and GDM groups (5.56 nmol/ml
and 3.98 nmol/ml) MDA values as compared to other groups. Vitamin E levels were significantly (p< 0.05) lower in PIH group
(0.38 mg/dl) as compared to other groups. Caesarean as a mode of delivery indicating more number of complications were higher
among GDM (61.9%) followed by PIH group. Incidences of low birth weight were observed more in PIH group. The study revealed
occurrence of oxidative stress and adverse outcome among high risk pregnancy groups. 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

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

Four groups of subjects: normal healthy normotensive nonpregnant women (Group A), normal normotensive pregnant women (Group
B), women with preeclamptic toxaemia (Group C) and eclamptic women (Group D): with fifty subjects in each group, were investigated
for serum lipid profile in the third trimester of pregnancy. There was significant increase in serum triglyceride and VLDL
cholesterol leve as well as decrease in LDL cholesterol in normal pregnancy, while total cholesterol and HDL cholesterol levels
did not show any statistically significant alteration. The preeclampsia (Group C) was associated with a significant rise in
triglyceride and VLDL cholesterol and fall in HDL cholesterol concentration, while eclamptic women showed significant fall
in HDL cholesterol and rise in LDL cholesterol as compared to normal pregnant women. However, interestingly, elevation of
the ratios of total cholesterol: HDL cholesterol and triglyceride: HDL cholesterol as well as diminuition of the ratio of
HDL cholesterol: VLDL cholesterol showed statistical significance in pregnancy induced hypertension in both Groups C and D,
while eclamptic women showed significant elevation of LDL cholesterol: HDL cholesterol ratio in addition. 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

The objective of the present study was to evaluate the changes in serum dehydroepiandrosterone (DHEA) and lipid peroxide levels
during ageing in human subjects. Random blood samples were collected from a total of 128 apparently normal human volunteers
of both sexes, whose age ranged between 21–70 years. The subjects were divided into groups of a decade years of age difference.
Serum levels of dehydroepiandrosterone (DHEA), lipid peroxides as malondialdehyde (MDA), and insulin were analysed in all
the subjects recruited in the study. In the present study there was decrease in serum DHEA levels with age (11.30 to 7.99
ng/ml). However the differences were significant only after 50 years up to 70 years. Serum MDA levels of these subjects were
higher (3.91 to 4.74 ng/ml) as compared to the values reported earlier (2.64 to 3.94 ng/ml). The serum MDA levels also showed
an increasing trend with age but the increase was significant only in the 40–50 years age group and values plateaud off at
later ages. The MDA and DHEA levels in women in general were lower than in men and this could be due to female hormones, which
are known to protect lipid against peroxidation. There was a significant negative correlation between age and DHEA (r=−0.311
P<0.05) and positive correction between MDA and age (r=+0.405 P<0.01). No significant differences were seen in serum insulin,
albumin and total protein levels. These preliminary findings support the possible utility of DHEA and MDA as markers for chronological
ageing. 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

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

Preeclampsia is a multisystem disorder associated with maternal hypertension, placental abnormalities and adverse fetal outcomes. The various pathways involved in its etiology include endothelial dysfunction, inflammatory milieu, lipid peroxidation and immunological imbalance. The present study was conducted to evaluate the causative and predictive role of nitric oxide, lipid peroxidation end products (MDA) and inflammatory cytokines (IL-6, TNF-α) in clinical presentation, severity and fetal outcome in preeclampsia. The study population was divided into 3 groups- Non- pregnant females comprising the control population; G1 and G2 groups included normal pregnant and pregnant females with preeclampsia with 50 patients in each group. Nitric Oxide and MDA levels were found to be highest in the preeclamptic patients as compared to other two groups. ROC curve analysis shows the superiority of the inflammatory markers as determinants of severity of preeclampsia which suggests the emerging role of pro inflammatory markers in the various pathological changes in preeclampsia. TNF-α emerged as the best marker in multivariate analysis and thus, has the potential for being used as a marker for PIH. Our study illustrates the multifactorial etiology of preeclampsia involving oxidative stress, proinflammatory milieu and endothelial dysfunction. 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

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 present study was carried out to evaluate the occurrence of association between homocysteine, folic acid and vitamin B(12) in patients with preeclampsia. Fifty preeclamptic patients from gynecology ward were studied for estimation of serum homocysteine, folic acid and vitamin B(12) over a period of October 2007 to June 2010. Serum homocysteine and folic acid, and vitamin B(12) were determined by means of Immulite 1000 analyzer. The statistical analysis of study group of preeclampsia compared with normotensive control group, showed significant alterations in serum homocysteine, folic acid and vitamin B(12) concentrations in preeclampsia. Inverse association between serum homocysteine and folic acid, and vitamin B(12) levels were observed in preeclampsia. The present study found hyperhomocysteinemia and deficiency of folic acid and vitamin B(12) along with increased blood pressure as a risk factor for cardiovascular disease (CVD) in preeclampsia. 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

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

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

Present study repots changes in serum copper levels (SCL) in various neoplastic diseases undergoing radiotherapy. We estimated
SCLs in 140 individuals comprising of 90 previously untreated patients with various malignancies and 50 healthy controls.
Patients received radiation in doses of 40–70 Gy in 4–7 weeks. SCLs were again estimated in patients following irradiation.
The mean SCL was significantly higher (P<0.001) in cancer patients as compared to healthy controls. It declined significantly
(P<0.001) following irradiation. However, it remained significantly higher as compared to healthy controls (P<0.01). Highest
fall in SCL was seen in complete clinical responders and least in non-responders to radiation treatment. Serial estimation
of SCLs may be useful in the treatment monitoring of the neoplasms undergoing radiation treatment. 相似文献

The prevalence of non-communicable diseases like diabetes mellitus (DM) and hypertension (HTN) is growing worldwide. Both lead to nephropathy if not controlled effectively. Microalbuminuria (MAU) is recognized as an early predictor for nephropathy. Additionally, the timely detection of advanced glycation end products (AGEs) is also considered to be an important prognostic factor for diabetic nephropathies. Hence, screening for the early detection of MAU and AGEs would be an useful and relatively inexpensive laboratory test for early clinical diagnosis for the incidence of nephropathy in these diseases. This study was conducted in DM, HTN and pregnancy induced hypertensive (PIH) subjects. MAU and Nε-Carboxymethyllysine (CML) levels were estimated by in-house RIA kits in the patient groups and controls, while the total AGEs level in serum was determined by ELISA. The levels of MAU, CML and AGE-BSA were observed to be significantly higher in DM, HTN and PIH subjects compared to controls (p < 0.001). Increased serum CML and AGEs levels in DM, HTN and PIH subjects indicated ongoing glycemic damage and their susceptibility to develop renal complications. 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

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

Background Pregnancy induced hypertension (PIH) contributes to 15.6% maternal mortality in India. In Behrampur, Orissa, maternal deaths
due to PIH was 32%, which is twice the national incidence. Hence in this population, some factors associated with severity
of PIH were studied. Serum lipid concentrations and malondialdehyde (MDA) levels were correlated with severity of PIH and
birth weight of the neonate.
Patients & Methods 70 primiparous PIH patients and 20 healthy controls were studied. Serum lipids and MDA were estimated. Maternal blood pressures
and birth weights of the neonate were recorded.
Results and Conclusion Serum cholesterol, triglyceride, LDL, VLDL and MDA were significantly elevated in primiparous PIH patients when compared to
control subjects. Average birth weight of babies born to mothers with PIH was less than those born to control subjects. The
most significant factor was that in this geographical area, 26% of the primiparous patients with PIH were below 20 years of
age while only 15% of the controls were less than 20 years, indicating that younger maternal age was a contributing factor
to PIH. 相似文献
