Lipid abnormalities remain to be a major cause of early mortality in patients with chronic renal failure (CRF). In present
study, 114 (one hundred fourteen) CRF patients without any additional cause of dyslipidemia were divided into groups on the
basis of etiologies of CRF. Blood samples from each group were analyzed for total cholesterol, triglyceride and HDL cholesterol
along with blood urea nitrogen and serum creatinine. 25 healthy individuals without any obvious disease were taken as control.
Patients from all the groups showed a marked hypertriglyceridemia of 232 (SD±77) mg/dl (P<0.001) as compared to control. Levels
of HDL cholesterol were found to be significantly low 20 (±11) mg/dl (p<0.001) in all the groups. LDL cholesterol showed an
increase 104 (±30) mg/dl as compared to control group which is not statistically significant. Present study reveals that,
CRF patients show an uniform dyslipidemia irrespective of etiologies leading to CRF. This dyslipidemia is also independent
of serum creatinine levels. Although, these lipid abnormalities may not solely cause mortality in CRF patients, they may act
as modulators in accelerating atherogenesis which in turn cause early mortality in CRF patients. 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 oxidative modification of lipoprotein especially low density lipoprotein (LDL) plays a key role in the initiation and
progression of atherosclerosis. Serum apolipoproteinB (apoB) level is found to be an important marker for atherosclerosis.
The present paper focuses on the measurement of serum apoB levels and the effect of Vitamin E, Vitamin C and reduced glutathione
on the copper ion induced oxidation of LDL + VLDL (VLDL-Very Low Density Lipoprotein) lipoprotein fraction isolated from the
serum of chronic renal failure (CRF) and renal transplanted patients. The level of apoB is significantly higher in the serum
of transplanted patients when compared to CRF patients and normal subjects. The level of TBARS formed in oxidized LDL + VLDL
lipoprotein fraction of CRF and renal transplanted patients are significantly increased than normal even in the presence of
antioxidants but the level of TBARS produced, with antioxidants is comparatively lesser than that produced by oxidized lipoprotein
fraction without antioxidants. It may be concluded than that produced by oxidized lipoprotein fraction without antioxidants.
It may be concluded that oxidation of LDL can be prevented at an earlier stage by Vitamin E supplementation. The supplementation
with Glutathione serves as the best method of preventing the lipoprotein oxidation among the renal diseased 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

An imbalance in the systemic redox status leading to oxidative stress has been an important factor in development of senile
cataracts, which is reflected by an increase in serum TBARS and a decrease in plasma SOD activity. Zinc has been an important
cofactor required for structural stability of SOD. In the present study the role of serum zinc level and plasma SOD activity
was analyzed in senile cataract patients showing significant oxidative stress. Serum TBARS, plasma SOD and serum zinc level
was measured in thirty randomly selected senile cataract patients against properly matched controls. Although, the analysis
of means showed a significant increase in serum TBARS and decrease in plasma SOD and serum zinc level in cases, but plasma
SOD was found to be just significantly correlated (p=0.05) with the serum zinc only in the cases. The results of partial correlation
studies and multiple regression analysis, also, showed only a significant correlation and predictable dependence between serum
TBARS and plasma SOD, excluding any role of serum zinc level. The present study concludes that it is chiefly the plasma SOD
activity, but not the serum zinc level, that determines the proneness of the patients for development of senile cataract. 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

Serum total lipids (cholesterol and triglyceride), lipoproteins (VLDL, LDL and HDL) and Apolipoprotein-B levels of normal
healthy individuals (n=25) and coronary artery disease patients (n=25) were estimated. The objective of the present study
was to ascertain the role of apo-B in causation and inheritance of coronary artery disease. It was observed that on an average
serum total cholesterol and triglyceride more than 200 mg/dl bring the individuals to a risk of coronary artery disease (CAD)
irrespective of the age. CAD patients achieved this value at an early age (35–45 years). Similarly VLDL and LDL levels were
found to be significantly raised in CAD patients when compared to that of age matched normal individuals, with patients achieving
risk values at an early age. HDL levels were found to be significantly lower in CAD patients as compared to normal individuals.
Serum apo-B levels were significantly raised in CAD patients as compared to age matched normal individuals. Patients with
positive family history of CAD had raised serum apo-B levels than those having negative family history. A positive coefficient
of correlation was observed between serum apo-B and LDL levels suggesting that more the number of Apo-B particles, more will
be the synthesis of atherogenic particle (LDL). Patients with negative family history had serum apo-B levels closer to those
of normal individuals and in these individuals HDL levels were found to be significantly lowered, suggesting that loss of
scavenger role of HDL could be the risk factor responsible for the causation of CAD in these patients, with negative family
history of coronary artery disease. 相似文献

Serum lipid profile, apolipoprotein-B (apo-B), malondialdehyde levels(MDA) and superoxide dismutase (SOD) activity were assessed
in 12 cases of xanthelasma with and without coronary artery disease (CAD)/hypertension (HTN) and results are compared with
healthy controls. Dyslipidemia was found in 65% cases of xanthelasma as compared to 20% healthy controls. Xanthelasma patients
had significantly high malondialdehyde (MDA) levels (p<0.01) and significantly decreased (p<0.05) SOD activity as compared
to controls. Among xanthelasma patients, xanthelasma with CAD/HTN showed higher total cholesterol (236±32.7 vs 188±24.7 mg/dl),
low density lipoprotein cholesterol (157±35.5 vs 113±16 mg/dl) and Apo-B (120.5±9.4 vs 114±19.2 mg/dl) levels as compared
to xanthelasma without CAD/HTN. Results of our study indicate that xanthelasma patients with increased apo-B, MDA and decreased
SOD need cardiovascular monitoring. 相似文献

This study confirms the fact that in different respiratory disorders, the status of plasma oxidants and antioxidants shifts
from normal. The status of oxidants in plasma as represented by malondialdehyde (MDA) levels increased significantly in the
conditions of chronic obstructive pulmonary disease (COPD), emphysema, bronchiectasis and bronchial asthma. The two vitamin
antioxidants vitamin C and vitamin E showed decreased levels than in controls. In patients with COPD the endogenous antioxidant
viz. reduced glutathione (GSH) estimated from whole blood was comparable to that of control group, whereas in patients with
emphysema, bronchiectasis and bronchial asthma, GSH concentration was increased to that of control group. The activity of
enzyme superoxide dismutase (SOD) was significantly decreased in all study groups. Pulmonary function tests were found to
have no correlation with MDA and antioxidants 相似文献

Retinopathy of prematurity (ROP) is a major cause of blindness in children. Free radicals are implicated in the development of this retinopathy. We studied the role of free radicals in ROP and enrolled 60 preterm neonates at 30–32 weeks age. Thirty neonates predisposed to development of ROP, were placed in study group and 30 normal neonates in control group. Malondialdehyde and antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPX) were measured in blood spectrophotometrically. Both the groups were followed-up to 40–42 weeks age. Serum MDA levels, erythrocyte SOD and plasma GPX were significantly high in study group at 30–32 weeks as compared to control group. At follow up visit significant increase in MDA level and decrease in SOD and GPX level among the study group was seen. This disturbance in equilibrium of oxidant and antioxidant status initiates an inflammatory process in retinal tissue leading to development of ROP. 相似文献

This study was conducted to find out the level of oxidative stress and effect of supplementation of vitamin C, D and Calcium
on levels of SOD, serum and urinary fluoride in children residing in endemic fluorosis area. For this the fluoride belt of
Jaipur district was selected. The parameters selected were Super oxide dismutase, serum fluoride and urinary fluoride. The
study was conducted on one hundred children, selected from four areas (25 from each area) consuming water containing 1.2,
2.4, 5.6 and 13.6 mg/l of fluoride. Drinking water fluoride, serum and urinary fluoride were measured by Ion selective electrode
method. Serum SOD by Xanthine oxidase method using kit of Ransod (kit cat. No. SD125). The post treatment values showed a
significant reduction in serum fluoride and SOD. Urinary fluoride levels increased significantly in post treatment stage.
The results revealed a normal SOD levels in all groups but an increasing trend was observed with increasing fluoride concentration.
Treatment with Calcium, Vitamin D and Vitamin C showed a significant reduction in serum fluoride and SOD and increase in urinary
fluoride. A high positive correlation between pretreatment and post treatment group was observed in serum fluoride, SOD and
urinary fluoride (P < 0.05). The study indicated an increasing oxidative stress in cases of fluorosis with increasing drinking
water fluoride concentration. Treatment with Calcium, Vitamin D and Vitamin C resulted a significant reduction in serum fluoride
and SOD and increase in urinary fluoride. 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

PCOS is a heterogeneous endocrine disorder with diverse clinical presentation. Oxidative stress plays a key role in the pathophysiology of this disease. Serumhigh sensitive C-reactive protein (hsCRP), a marker of chronic low grade inflammation, is indicative of future development of cardiovascular disease. Our aim is to evaluate the oxidant status and hsCRP levels in PCOS. The study involved 61 cases and 61 controls in the age group of 18–40 years diagnosed with PCOS. Erythrocyte malondialdehyde (MDA), superoxide dismutase (SOD), serum hsCRP, gonadotrophins, thyroid stimulating hormone, prolactin, glycemic status and lipid profile were estimated. Erythrocyte MDA (p < 0.001), SOD (p = 0.007) and serum hsCRP (p < 0.001) were significantly elevated in PCOS patients than controls. Oxidative stress is present in women with PCOS along with elevated hsCRP. 相似文献

Multiple myeloma is a disseminated malignancy of monoclonal plasma cells that accounts for 15 % of all hematological cancers. The present study was conducted to evaluate the role of inflammation and oxidant-antioxidant dynamics in the etiology of this disease. The study population comprised of 20 cases of multiple myeloma and 20 healthy controls. The parameters evaluated were serum malondialdehyde (MDA), superoxide dismutase (SOD) and ferritin levels. The serum MDA levels were 1.9 ± 0.96 nmol/ml in cases as compared to 0.98 ± 0.55 nmol/ml in the controls. Similarly, a statistically significant difference was noted in the SOD and ferritin levels between the cases and controls (93.2 ± 23.8 vs. 210.1 ± 190.5 U/ml and 285.8 ± 216.4 vs. 131.8 ± 30.1 ng/ml respectively). Our study highlights the imbalance in the oxidant-anti oxidant mechanism and the role of smoldering inflammation in the etiology of multiple myeloma. 相似文献

Coronary artery disease is now a major health problem in India. In past few decades the battle to reduce the incidence of
coronary artery disease has led the researchers to look for various clinical markers, which would help early diagnosis of
the diseases. The present study was undertaken to assess the level of lipoprotein (a) [Lp(a)] and few other lipids in selected
myocardial infarction (MI) patients below 45 years without having any traditional risk factors but with positive family history.
Fasting blood samples were taken from 65 patients and their total cholesterol, LDL cholesterol, VLDL cholesterol, HDL cholesterol,
triglycerides and serum Lp(a) were determined. The control group consisted of 50 age matched healthy individuals. The mean
Lp(a) level was 58.6±3.20 mg/dl in patients and 19.70±0.18 mg/dl in controls. Thus Lp(a) levels were found significantly higher
in patients with MI (p<0.05 for patients versus control) as compared to the controls. There was no significant difference
in the levels of total cholesterol (TC), LDL, VLDL HDL, TGL as compared to controls but there was an increase in TC/HDL cholesterol
ratio. The results of this study suggest that high level of Lp(a) and TC/HDL ratio has a distinctive association with MI,
independent of other common coronary risk factors. Hence, Lp(a) level in serum emerges to be a promising marker for diagnosis
of coronary artery diseases. 相似文献

A 24 week follow-up study on lipid change following maintenance haemodialysis (MHD) in 25 chronic renal failure (CRF) patients
revealed significantly raised serum Triacylglycerol (TAG) levels in these cases (P<0.001), while cholesterol and HDL-Cholesterol
did not show any significant change, the extent of increase was 10.5±3.6% after 12 weeks and 23.0±5.8% after 24 weeks. Corresponding
increase in CRF patients treated conservatively, without haemodialysis, were 3.1±1.2% and 7.2±2.7% at these intervals. Subsequent
oral administration of L-Carnitine (5mg/kg body weight twice a day) for three weeks brought about a significant reversal of
elevated serum TAG level in MDH group as well as in the conservatively treated group (P≤0.05).
It is concluded that the haemodialysis induced Hyper-Triacylglycerolemia of CRF patients is revertible by Carnitine replenishment.
Even the concomitant increase in conservatively treated group is revertible by carnitine administration. 相似文献

A number of epidemiologic studies has been published in recent years showing an increase risk of death from cancer in subjects
with low plasma cholesterol levels. Although several authors proposed that hypocholesterolemia is predisposing factor for
cancer development, no causative relation has been established so far and that it may be that low plasma cholesterol is secondary
to malignant disease. Hence, the present study was undertaken to examine the lipid profile in children patients with leukemia
and Hodgkin's disease in comparison with age matched controls. The study included 52 normal healthy controls and 105 patients
with leukemia and Hodgkin's disease. Lipid profile included serum cholesterol, HDL & LDL cholesterol and triglycerides. Serum
cholesterol, HDL & LDL cholesterol were found to be inversely associated with incidence of cancer, whereas triglycerides were
significantly elevated in cancer patients. The inverse association between cancer and serum cholesterol may reflect a physiological
response to early undiagnosed stages of cancer. 相似文献

The effects of regular feeding ofPyrus malus whole fruit and its juice on total serum cholesterol, HDL cholesterol, LDL cholesterol, triglycerides and phospholipids have been studied in normal albino rabbits. It was observed that the whole fruit as well as juice caused significant and progressive decrease in total serum cholesterol, LDL cholesterol and triglycerides within a period of 30 days. On the other hand, serum phospholipids and HDL cholesterol showed progressive and significant increase. Apparently, whole fruit appeared to bring about more per cent lowering in total cholesterol, LDL cholesterol and more increase in HDL cholesterol as compared to juice. Whole apple fruit also caused increase in body weight of rabbits on 30th day (p<0.05) while oral administration of juice showed insignificant change in body weight even on 30th day (p>0.05). 相似文献

Pathogens, especially Gram-negative bacteria or bacterial endotoxin, along with other classical factors, may be involved in
inflammatory response within the aortic endothelium during the progression of cardiovascular disease. Studies have shown that
bacterial endotoxin activates various inflammatory processes in the body. Our study aims to establish a correlation between
endotoxemia and vascular expression of antioxidant enzymes. Swiss albino mice (4 weeks old) were fed a high fat diet for 24
weeks and then were administered Escherichia coli endotoxin intraperitonealy, for 4 weeks. Tissue antioxidant enzymes, serum
levels of IL-6 and TNF alpha were measured from the mice. We report that i.p. administration of endotoxin to hyperlipidemic
mice resulted in elevation of superoxide dismutase and catalase enzymes, which was paralleled by a systemic reduction of serum
cholesterol and LDL expression. Myeloperoxidase levels were also found to be elevated in aortic tissue, while an increase
was also observed in the serum cytokine levels. 相似文献
