Appropriate therapeutic measures can improve the life expectancy of patients with ovarian malignancy. There has been a pressing
need for serodiagnostic assays to enable, the close patient monitoring. Cancer Antigen 125 (CA125) has been described as a
useful marker in patient monitoring for ovarian malignancy. Keeping this in view, the present study was planned. 40 consecutive
female patients of ovarian carcinoma (mean age 52.4±10.7 years) were selected for serum CA125 analysis during the period of
year 1995–2001. The tumour marker concentration was compared with histologic types of ovarian tumour and the FIGO staging
of the disease. 25 healthy females (mean age 35.2–10.4 years) served as control. Mean serum CA125 concentrations in patients
with papillary serous adenocarcinoma(Mean±%CV 1571±121.5 U/ml) was much higher than patients with mucinous adenocarcinoma(775±78U/ml).
Mean serum CA125 concentration in endometrioid carcinoma was very high(2853±136 U/ml). The patient with clear cell carcinoma
however had shown moderate increase(60 U/ml). No correlation was found between serum CA125 concentration and the FIGO staging
of disease.
Quantitation of CA125 was most helpful in monitoring the response of treatment and followup of the patients after completion
of their treatment. Posttherapeutically its concentration showed more than 50% reduction in almost all (91.4%) patients (P<0.001).
Importantly these patients had also shown significant regression of the disease clinically and radiologically. 8.6% of patients
had shown static or increase in serum CA125 concentration which was associated with either clinically static or progressive
disease. Recurrence of the disease was noted in patients who had shown increase in serum CA125 concentration (biochemical
recurrence) in the followup
However, in our test population biochemical recurrence(increase in serum marker concentration) preceded the clinical or radiological
recurrence by an average of 6.5 months.
Kaplan meier survival analysis for evaluation of overall survival in our test subjects showed an overall survival of 32% at
one year and median survival of 9 months with confidence interval of 6.34 to 11.66. We conclude that serum CA125 is a useful
marker for monitoring the treatment and predicting an early recurrence of the disease in ovarian carcinoma patients. A study
in larger number of patients is needed to define its exact role in the management of the carcinoma ovary. 相似文献

Serum malondialdehyde was measured in sixty-one falciparum malaria cases, which include thirty uncomplicated, and thirty-one
complicated with acute renal failure. Twenty-six healthy individuals were also studied as controls. Serum malondialdehyde
level was found to be significantly elevated in falciparum malaria induced acute renal failure cases when compared with uncomplicated
falciparum malaria (p<0.001) and healthy controls (p<0.001). A positive correlation with the raised urea, creatinine and bilirubin
levels were significant (r=0.62, p<0.025; r=0.65, p<0.05 and r=0.72, p<0.001 respectively) indicating the severity of complication
with rise of lipid peroxides in falciparum malaria induced acute renal failure cases. 相似文献

Serum sialic acid levels were determined in 66 patients of carcinoma cervix and 25 control women matched for age. Mean sialic acid level was significantly elevated (p<0.001) in cancer cervix patients as compared to controls. Patients were treated with 50–65 Gy of radiation in 5–6.5 weeks. Post-therapy levels were again determined. Radiotherapy caused decline in serum sialic acid level in all the patients except one. Mean post-therapy level was significantly lower as compared to pretreatment level (p<0.001). It was also observed that fall in sialic acid level was significantly higher (p<0.05) in early stage patients as compared to late stage. No relationship was observed in the dose of radiation and fall in serum sialic acid level. A significantly higher fall in serum sialic acid level was observed in patients having complete clinical response as compared to partial or nonresponders to radiation treatment (p<0.001). 相似文献

The present study comprised 100 patients of essential hypertension who were screened for fasting hyperinsulinemia, which was
detected in 77% cases. Twenty such hyperinsulinemic cases were subjected to 4 weeks of dietary control phase followed by 6
weeks of omega-3 fatty acids substitution [either 0.6 g/d (group 1) or 1.2 g/d (group 2)]. The mean basal fasting plasma insulin
levels were significantly higher (p<0.001) in patients of hypertension when compared to normal controls (126.51±80.36 and
19.35±12.61 μU/ml respectively). At the end of 4 weeks of diet control only, no significant change was observed in any parameter.
After substitution of omega-3 fatty acid, a significant reduction of fasting plasma insulin levels in both group 1 (29%) and
group 2 (22.8%) was observed (p<0.001). Significant reduction of systolic and diastolic blood pressure (16.4% and 25% respectively),
serum cholesterol, triglycerides and low density lipoprotein was also noted in both groups (p<0.001), while high density lipoprotein
increased by ∼8 mg% in both groups. Thus omega-3 fatty acid substituion in low dose along-with curtailment of dietary omega-6
fatty acid may be used as an adjunctive measure in the management of essential hypertension. 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 demonstrates the incidence of increased lipid peroxidation and protein oxidation in both maternal and fetal
erythrocytes as markers of oxygen radical activity in different complications of pregnancy. In fetuses born after premature
rupture of membranes, lipid peroxidation was significantly elevated as indicated by increased malondialdehyde levels (p<0.05)
as compared to controls. Proteolytic activity in the erythrocytes of mothers in this group was also significantly high (p<0.01).
In patients delivered by lower segment cesarian section, lipid peroxidation and proteolytic activity in maternal erythrocytes
were significantly high (p<0.05 and p<0.001 respectively). In patients with prolonged second stage of labour, lipid peroxidation
and proteolytic activity in maternal erythrocytes was significantly higher than in controls (p<0.001 and p<0.05 respectively).
In this group, endogenous protein damage due to oxidative stress was significantly high both in the mother and the fetus (p<0.001
and p<0.05 respectively). 相似文献

Stroke is the third leading cause of death and foremost cause of disability. Based on studies in CAD patients, a focus has
been shifted on genetic and inflammatory markers as risk factors for stroke besides deranged lipid profile. The present study
was aimed to ascertain the role of Lipoprotein (a), C-Reactive protein (CRP) levels and lipids in patients of ischemic stroke.
The study was done in 82 subjects including 40 Computerized Tomography (CT) proven patients of ischemic stroke and 42 age
and sex matched controls. Complete biochemical parameters including lipid profile were carried out on autoanalyzer using standard
kits and reagents. Lipoprotein (a) [Lp(a)] was determined by immunoturbidimetric assay. Atherogenic indices (Total cholesterol/
HDL, LDL/HDL and Lipid Tetrad Index) were calculated using these lipid parameters. The CRP levels were measured semi-quantitatively
by latex agglutination test method. Out of 40 stroke patients, 38 had abnormalities in lipid profile (As per ATP III guidelines).
A significant difference was seen in serum cholesterol, LDL cholesterol and atherogenic indices between the patients and controls.
The difference in CRP levels in cases and control subjects was highly significant (4.78±0.72 mg/dl vs 0.76 ±0.70, p<0.001).
96.5% of patients with raised CRP had abnormal lipid levels also. CRP levels in stroke patients showed significant correlation
with total cholesterol and LDL (p<0.001), Lp (a) (p=0.002) and atherogenic indices (p<0.05). Raised CRP levels in stroke patients
were significantly associated with large territory infarcts, severe disability and poor functional outcome (p<0.05).Genetic
[Lp(a)], metabolic (deranged Lipid profile) and inflammatory factors (CRP) together are instrumental in causing cerebrovascular
arteriosclerosis leading to ischaemic stroke and can be used as important markers to identify patients at risk of severe stroke
and to institute aggressive preventive strategies. 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

Serum cardiac troponin T (cTnT) and CKMB (mass) were analysed in three groups of patients. The first group (n=32) were patients
with acute coronary syndromes including myocardial infarction. The second group (n=35)were patients with hypertension. The
third group (n=24) were patients who had succumbed to non cardiac diseases. In all 3 groups, cardiac troponin T was elevated
when compared with controls (p<0.001). However, CKMB elevation was not significant in all groups. CKMB levels correlated well
with troponin T levels only when CKMB was greater than 50 ng/ml (r=1.00). Small elevations of troponin T identifies minimal
cardiac necrosis and patients can benefit from early invasive therapy. 相似文献

Repeated blood transfusion in beta thalassemia major patients may lead to peroxidative tissue injury by secondary iron overload.
In the present study, 72 children with beta thalassemia major were included. Serum levels of total lipid peroxides, Iron,
Total Iron Binding Capacity, Copper, Zinc, Vitamin E, plasma Total Antioxidant Capacity, activity of Erythrocyte Superoxide
Dismutase, were measured. The findings were compared with 72 age matched healthy controls irrespective of sex. A significant
increase in the levels of lipid peroxide and Iron (p<0.001), whereas, significant decrease in the levels of vitamin-E, Total
Antioxidant Capacity and Total Iron Binding Capacity (p<0.001) was observed. Serum Zinc was significantly increased (p<0.001)
with significant decrease in the levels of copper (p<0.001). Non Significant increase in the activity of Erythrocyte Superoxide
Dismutase (p>0.05) was found in the patients when compared with controls. This suggest that oxidative stress and reduced antioxidant
defense mechanism play an important role in pathogenesis of beta thalassemia major. 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

The study includes 102 confirmed cases of carcinoma breast with and without metastasis and 25 healthy non-pregnant females.
They were evaluated for blood levels of Ferritin, GSH, LDH, ALP, GGT and Hb before and 21 days after mastectomy. A significant
increase (p<0.001) was observed in ferritin, LDH and GSH levels in cancer patients without metastasis in comparison to normal
control subjects. Patients with metastasis had further elevated (p<0.001) levels of Ferritin, ALP and GGT as compared to non-metastatic
patients. Mastectomy in both the cases i.e. with and without metastasis resulted in non-significant decrease in all the biochemical
parameters suggesting that longer follow up could confirm post surgery decrease in the biochemical parameters. The results
of the study suggest cost effective, usefulness of Ferritin, ALP, GGT and GSH/Hb ratio in differentiating breast cancer patients
with and without metastasis which can be assayed in smaller laboratories. 相似文献

Peganum harmala L. (Zygophyllaceae) is a traditional medicine used for the treatment of variety of human ailments, including
antidepression, hallucination, antileishmaniasis etc. We report for first time the hypoglycemic activity of the ethanolic
extract of this plant at two dose levels of 150 and 250mg/kg bw in sucrose challenged normal as well as in rats with streptozotocin
induced diabetes. The oral administration of ethanolic extract causes maximum fall of blood glucose level to 22.9% (p<0.05)
and 29.4% (p<0.01) respectively with the two doses in normal and 30.3% (p<0.01) and 48.4% (p<0.001) in diabetic rats. The
standard drug metformin treated group showed 28.0% (p<0.01) and 45.5% (p<0.001) respectively in normal and diabetic rats.
The above results show that the ethanolic extract of P. harmala is as effective as metformin in reducing the blood glucose
levels of normoglycemic and streptozotocin-induced diabetic rats. 相似文献

Tubular damage is a complication associated with nephrotic syndrome and increased levels of urinary enzymes are of significant
value in detection of the same. The aim of our study was to evaluate the use of urinary lysozyme and trehalase as markers
of tubular dysfunction in nephrotic syndrome. This study assessed 35 nephrotic syndrome patients and 30 healthy controls matched
for age and sex. Urine samples were examined at pretreatment and post treatment (8 weeks) stages for proteinuria, lysozyme
and trehalase. At pretreatmant stage there was significant increase in urinary lysozyme and trehalase as compared to controls
(p<0.001). A good correlation was observed between degree of proteinuria and urinary lysozyme (p<0.001;r=0.80) and trehalase
(p<0.001; r=0.74). At the end of 8 weeks of treatment, the patients showed significant decrease in their urinary lysozyme
and trehalase activity (p<0.001) but no correlation with degree of proteinuria was observed. Our results indicate that enzymes
like lysozyme and trehalase can be used as markers of tubular dysfunction. 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

Salivary β-glucuronidase activity was studied in 20 healthy subjects without habits and 10 with habits, 38 untreated patients
of advanced head and neck cancer and 21 patients after treatment either after surgery or radiation.
Salivary β-glucuronidase activity was elevated in untreated cases of head and neck cancer (p<0.001), with a fall in the activity
after treatment. The post operative fall in the activity of salivary β-glucuronidase activity was highly significant (p<0.001)
as compared to post radiation. This test can be utilized in the diagnosis and also for monitoring the course of the disease. 相似文献

In the present study, 58 diabetic patients (type II) comprising uncomplicated (27) and complicated (31) cases along with 38 healthy matched controls were investigated for glycosylated hemoglobin (HbA1), glycosylated serum proteins (GSP) and serum lipid profile viz. triacylglycerol, total cholesterol, HDL-cholesterol (HDL-C), VLDL-C, LDL-C and their ratios. HbA1 and GSP were significantly elevated in diabetic group as a whole when compared with controls (p<0.01), but comparison of mean values of complicated and uncomplicated group revealed (though higher in complicated) that the difference between two groups was not statistically significant (p>0.05). Follow-up studies showed that while GSP levels reflect variations in blood glucose over a shorter period of 15 days, those of HbA1 do so for about 3 months. HbA1 correlated with fasting blood glucose (p<0.01), whereas GSP showed correlation with both fasting (p<0.01) and postprandial (p<0.05) blood glucose. Hypercholesterolemia and hypertriacylglycerolemia were observed (p<0.01) in both the groups. However no significant change was seen in HDL-C (p>0.05) even after accounting for sex in both the groups. Interestingly TC:HDL-C was elevated significantly (p<0.01) in the above groups. These findings seem to suggest that at the levels of hyperglycemia, hypercholesterolemia and hypertriacylglycerolemia observed, some patients are prone to develop complications earlier. 相似文献

The objective of the study was to estimate the serum concentrations of oxidative stress markers-lipid hydroperoxide (MDA-Malondialdehyde),
lactate dehydrogenase (LDH), nitrite; and ferric reducing antioxidant power (FRAP) — a measure of total antioxidant capacity
in serum. Serum nitrite levels were high in fertile women than in infertile women (p<0.001), whereas MDA was high in infertile
women than in fertile group (p<0.018). On classifying the entire group of women with infertility based on the etiology, serum
MDA and LDH levels were higher in women with infertility due to unexplained factor than in women with other causes contributing
to infertility compared to controls (p<0.001, p<0.02). A positive correlation among serum prolactin and nitrite suggested
that hyperprolactinemia could contribute to infertility by inducing oxidative damage. Serum FRAP levels showed no significant
difference in the groups studied. Lipid peroxidation was high in women with unexplained infertility which may be due to hyperprolactinemia. 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

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
