The present study was conducted to assess correlation of ammonia levels with valproate levels in epileptic patients presenting
with valproate toxicity and also whether liver enzymes and ammonia levels could serve as biochemical marker of valproate toxicity.
100 patients with epilepsy who had received valproate therapy for more than 12 months and had presented with valproate toxicity
and 100 controls were included in the study. The serum valproate, ammonia and liver enzymes were measured in these subjects.
In patients with valproate toxicity, the mean level of serum valproate was 110.91 ± 28.68 mg/dL (therapeutic range 50–100
mg/dL). Serum ammonia was higher (86.37 ± 39.90 μg/dL) in patients with valproate toxicity compared to controls (68.73 ± 30.07
μg/dL). Out of 100 patients, only 37 patients had serum valproate level > 120 mg/dL and 22 patients had raised levels of valproate
as well as ammonia. Age < 30 years and serum ammonia > 69 μg/dL is risk factors for valproate toxicity. Serum ammonia, liver
enzymes should be regularly investigated in patients on valproate therapy for early diagnosis of valproate toxicity. 相似文献

Serum ceruloplasmin is one of the most commonly used screening tests for Wilson’s disease. However immunological assays for
ceruloplasmin are not recommended for diagnosis and management of Wilson’s disease through calculation of free copper index.
Enzymatic methods using non-physiological substrates have toxicity and stability problems, making them difficult to automate.
Ferroxidase assays may be a satisfactory alternative for measuring serum ceruloplasmin. The o-dianisidine hydrochloride manual
method for estimation of serum ceruloplasmin enzyme activity was compared with an automated method using the ferroxidase activity
of ceruloplasmin in measurement in a double blind study in 91 consecutive patients screened for Wilson’s disease. The o-dianisidine
and ferroxidase methods both successfully identified 7 patients with Wilson’s disease. Values for these 7 patients in the
o-dianisidine and ferroxidase methods were median 5.0 (range 0–16.0 U/L) and median 45.0 (range 4–166 U/L) respectively. There
were 7 other positive values (<62 U/L) with the o-diansidine method and 2 (<200 U/L) with the ferroxidase method, where WD
was not confirmed. ROC curves for both methods showed area under the curve of 0.998 for o-dianisidine and 0.997 for ferroxidase.
Using literature cut off values of 62 U/L and 200 U/L respectively both methods had 100% sensitivity and specificity was 91.7%
(o-dianisidine) and 97.6% (ferroxidase). For the o-dianisidine assay, specificity was improved to 98.8% using a cut off of
22.5 U/L. In the 84 persons (46 adults and 38 children) in whom the diagnosis of Wilson’s disease was not established, the
mean value for ceruloplasmin activity by the o-dianisidine and ferroxidase methods was 124.7 ± 48.7 U/L and 571.4 ± 168.1
U/L respectively. There were no significant differences between sex or age of patients (p > 0.29). In a subsequent evaluation
with 372 specimens, the Pearson correlation coefficient between the assays was 0.908, p < 0.01, slope 4.06, intercept 265.8,
with the manual assay as the x-axis. The ferroxidase assay is a suitable replacement for the o-dianisidine assay in detecting
patients with Wilson’s disease. 相似文献

The study was designed to evaluate the antioxidant activity and effect of Cymbopogon martinii (Roxb.) Wats. (Poaceae) leaves on the activity of monoamine oxidase and kinetics of enzyme inhibition. Ethanol extract of
C. martinii and rat brain mitochondrial monoamine oxidase preparation ware used to study the kinetics of enzyme inhibition using double
reciprocal Lineweaver–Burk plot. The DPPH was used as a source of free radical to evaluate antioxidant potential. It is observed
that, the ethanolic extract of C. martinii inhibits the monoamine oxidase activity with competitive mode of inhibition. The V
max (0.01 mM/min) remained constant while, K
m varied from 21.00 ± 1.1, 43.33 ± 1.5 and 83.33 ± 1.4 mM for 100–500 μg/ml concentration of C. martinii. The K
i values were calculated to be 90.00 ± 0.87, 75.00 ± 0.69, 68.18 ± 0.68 μg for 100–500 μg/ml concentration of C. martini. It also shows a significant DPPH (1,1-diphenyl-2-picryl hydrazine) radical scavenging (IC50 = 0.34 ± 0.05 mg/ml) and reducing activity (IC50 = 0.70 ± 0.22 mg/ml). The C. martini can be considered as a possible source of MAO inhibitor used in the treatment of depression and other neurological disorders. 相似文献

Homocysteine (Hcy) is a non-protein forming amino-acid, whose metabolism is at the intersection of two metabolic pathways:
remethylation and transsulfuration which are dependent on the vitamins folic acid, B12 and B6, and the enzymes methylenetetrahydrofolate reductase and cystathionine-β-synthetase. A deficiency of any of these vitamins
or enzymes results in hyperhomocysteinemia. This causes oxidative and other damage to blood vessels, thus affecting various
organ systems of the body. As part of our ongoing research on cardiovascular risk factors, we have studied the Hcy levels
in the plasma of normal controls and those suffering from vascular diseases. It was observed that Hcy is significantly higher
in patients of vascular diseases (21.59±1.28 μmol/L, mean±SEM), as compared to normal controls (11.33±0.18 μmol/L). This significance,
was more pronounced in cases of venous thrombosis (26.77±2.43 μmol/L) as opposed to cases of arterial block (17.27±0.84 μmol/L).
This signifies that Hcy estimation would be beneficial in obtaining a differential diagnosis in addition to being a modifiable
vascular risk factor. 相似文献

Lead poisoning remains a major problem in India due to the lack of awareness of its ill effects among the clinical community.
Blood lead, δ-aminolevulinic acid dehydratase (δ-ALAD) and zinc protoporphyrin (ZPP) concentrations are widely used as biomarkers
for lead toxicity The present study was designed to determine the impact of chronic lead exposure on selected biological markers.
A total of 250 subjects, of both sexes, ranging in age from 20 to 70 years, were recruited. On the basis of BLLs, the subjects
were categorized into four groups: Group A (BLL: 0–10 μg/dl), Group B (BLL: 10–20 μg/dl). Group C (BLL: 20–30 μg/dl) and Group
D (BLL: 30–40 μg/dl) having BLLs of 3.60 ± 2.71 μg/dl, 15.21 ± 2.65 μg/dl, 26.82 ± 2.53 μg/dl and 36.38 ± 2.83 μg/dl, respectively.
Significant changes in biological markers due to elevated BLLs were noted. The relation of BLL and biological markers to demographic
characteristics such as sex, habits, diet and substances abuse (smoking effect) were also studied in the present investigation.
Males, urban population, non-vegetarians, and smokers had higher blood lead levels. δ-ALAD activity was found to be significantly
lower with increased BLL (P < 0.001), while the ZPP level was significantly higher with increased BLL (P < 0.001). Further, BLL showed a negative correlation with δ-ALAD (r = −0.425, P < 0.001, N = 250) and a positive correlations with ZPP (r = 0.669, P < 0.001, N = 250). Chronic lead exposure affects the prooxidant-antioxidant equilibrium leading to cellular oxidative stress. 相似文献

It has been proposed that oxidative stress plays an important role in male infertility. The aims of this study were to compare
seminal plasma levels of 15-F2t-isoprostane (8-iso-PGF2α), malondialdehyde (MDA), and total (sum of free and bound) homocysteine
(tHcy) from normozoospermic vs. asthenozoospermic men, and to examine the relationships between tHcy and lipid peroxidation
products. The study was a case-control study with a simple random sampling. The case group was consisted of 15 asthenozoospermic
males. This group was compared with 15 normozoospermic men. Seminal plasma levels of 15-F2α-isoprostane and tHcy were measured
using commercially available enzyme immunoassay (EIA) kits. MDA levels were determined by the thiobarbituric acid (TBA) assay.
The Mann-Whitney U test was used to compare two groups. Coefficients of correlation were calculated using Spearman’s correlation
analysis. All hypothesis tests were two-tailed with statistical significance assessed at the p value <0.05 level. MDA levels
were higher in asthenozoospermic subjects than in control subjects (0.72±0.06 μM vs. 0.40±0.06 μM; p<0.05). No differences
were seen in 15-F2α-isoprostane levels in asthenozoospermic subjects and controls (65.00±3.20 pg/ml vs. 58.17±4.12 pg/ml;
p>0.05). Interestingly, tHcy levels were to be slightly higher in asthenozoospermic subjects than in controls (6.18±1.17 μM
vs. 4.8±0.52 μM). Sperm motility was inversely correlated with seminal plasma 15-F2α-isoprostane and MDA levels, respectively
(p<0.05). In summary, seminal plasma levels of 15-F2α-isoprostane and tHcy showed no significant difference between normozoospermic
and asthenozoospermic men. Sperm motility was not correlated with seminal plasma levels of tHcy. No relationship was found
between tHcy and lipid peroxidation. 相似文献

Short-chain acyl-CoA dehydrogenase (ACAD) deficiency is an extremely rare inherited mitochondrial disorder of fat metabolism.
This belongs to a group of diseases known as fatty acid oxidation disorders. Screening programmes have provided evidence that
all the fatty acid oxidation disorders combined are among the most common inborn errors of metabolism. Mitochondrial beta
oxidation of fatty acids is an essential energy producing pathway. It is a particularly important pathway during prolonged
periods of starvation and during periods of reduced caloric intake due to gastrointestinal illness or increased energy expenditure
during febrile illness. The most common presentation is an acute episode of life threatening coma and hypoglycemia induced
by a period of fasting due to defective hepatic ketogenesis. Here, the case of a 4 month old female patient who had seizures
since the third day of her birth and persistent hypoglycemia is described. She was born to parents of second degree consanguinity
after 10 years of infertility treatment. There was history of delayed cry after birth. Metabolic screening for TSH, galactosemia,
17-OHP, G6PD, cystic fibrosis, biotinidase were normal. Tandem mass spectrometric (TMS) screening for blood amino acids, organic
acids, fatty acids showed elevated butyryl carnitine (C4) as 3.40 μmol/L (normal <2.00 μmol/L), hexanoyl carnitine (C6) as
0.92 μmol/L (normal <0.72 μmol/L), C4/C3 as 2.93 μmol/L (normal <1.18 μmol/L). The child was started immediately on carnitor
syrup (carnitine) 1/2 ml twice daily. Limitation of fasting stress and dietary fat was advised. Baby responded well by gaining
weight and seizures were controlled. Until now, less than 25 patients have been reported worldwide. The limited number of
patients diagnosed until now is due to the rarity of the disorder resulting in under diagnosis. 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

Determination of plasma total homocysteine by high-pressure liquid chromatography (HPLC) usually requires reduction of protein
bound or free homocysteine-disulphides into thiols by a reducing agent and the liberated thiols are then derivatized by a
fluorescent marker. In this study we have standardized the HPLC method for homocysteine measurement using dithiothreitol (DTT)
as reductant.
The results of plasma total homocysteine values obtained by HPLC were compared with IMx method. The difference between the
two means was statistically insignificant [P=0.616847 (two tail)] Linear regression analysis showed strong correlation between
the two methods (r=0.983). Using this method we have analyzed 132 controls and 130 Coronary Heart Disease (CHD) patients for
plasma total homocysteine, wherein, the mean plasma total homocysteine levels were 10.51±8.36 and 11.51±10.06 μmol/L respectively.
Our research study suggests that DTT method is a simple and inexpensive assay for homocysteine determination in human plasma
for research application. 相似文献

Blood zinc protoporphyrin (ZPP), serum total protein (TP), and total cholesterol (TC) levels in automobile workshop workers
in relation to lead toxicity were analysed. In the present study, automobile workshop workers (healthy male workers at an
age between 28 and 35 from four major automobile workshops in Kottayam, Kerala State, India) and the control (male healthy
adults at an age between 28 and 35 residing at Aymanam, a distant village at Kottayam District, Kerala having reduced or no
chance of lead exposure) displayed significant difference in blood lead (BPb) and blood ZZP (BZPP) level. The mean value of
BPb in automobile workshop workers was 15.76±0.33 μg/dl, while in the control it was 8.20±0.15 μg/dl. In automobile workshop
workers, the mean value of BZPP was 34.2±0.62 μg/dl. The control group exhibited a mean of 11.5±0.22 μg/dl. Automobile workshop
workers exhibited significant increase in BZPP was corresponding to the increase in BPb level. The total protein levels estimated
in automobile workshop workers showed significant decrease compared to control individuals, but was within the reference range
of healthy individuals. The mean value of TP level in automobile workshop workers and control was 6.9±0.13 g/dl and 7.71±0.18
g/dl, respectively. There was no significant difference in blood haemoglobin (BHb) level among the automobile workshop workers
and control. The serum TC level in automobile workshop workers showed significant decrease compared to the control individuals,
but was with in the reference range of healthy individuals. The mean level of serum TC in automobile workshop workers was
162.00±3.44 mg/dl and the same in control was 172.86±4.32 mg/dl. The present study affirms occupational lead toxicity in automobile
workshop workers and its effect on serum protein and cholesterol levels. 相似文献

The objective of this study was to evaluate acrosin activity in spermatozoa of infertile Nigerian men and to compare with
those of the fertile men. The acrosin activity was evaluated using the Acroscreen reagent kit. The acrosin activity of the
fertile men was 40.7±5.2 mIU/106 sperm (range 30.1–51.3) and those of the infertile men was 22.4±8.33 mIU/106 sperm (range 5.7–39.1). The difference in the mean was statistically significant (P<0.001). There was a subpopulation of
the infertile men who had their acrosin activity within normal range of the fertile men, 32.9±1.57 mIU/106 sperm. But the difference in the mean was statistically significant (P<0.001). Acrosin activity decreased with increased
morphological changes in the spermatozoa. It is concluded that acrosin activity in the infertile Nigerian men is significantly
lower than that in the fertile men. Acrosin activity may also be affected by morphological changes in the spermatozoa. 相似文献

Oxidative stress is thought to be involved in the pathophysiology of malaria, especially in pregnancy where natural resistance
is markedly reduced. In the present study we investigated oxidative stress in 315 pregnant women out of which 159 had Plasmodium
falciparum malaria and 154 controls. We evaluated the level of lipid peroxidation products (MDA level) in the plasma, the
activity of erythrocyte antioxidant defense enzymes, superoxide dismutase (SOD, EC: 1.15.1.1) and catalase (Cat, EC: 1.11.1.6)
as well as the ability to resist oxidative stress by the FRAP (Ferric Reducing Ability of Plasma) assay. Total erythrocyte
protein levels were also examined. For the two groups of patients, several differences between the biochemical parameters
tested were found. Median parasitaemia in women with malaria was 25,392 parasites/μl of blood (Range1200–82000), while in
controls we had no parasites found in thin and thick smears. Levels of lipid peroxidation products (MDA) were significantly
higher in patients with parasitemia than in healthy asymptomatic volunteers (mean: 0.844 ± 0.290 and 0.384 ± 0.129 respectively,
p<0.001). This MDA level was higher in primigravidea and also correlates well with parasite density (p<0.001). Catalase activity
in erythrocytes of women with malaria did not differ statistically from that of controls. In contrast, SOD activity of patients
with malaria was found to be significantly higher than that of controls (mean: 0.7899 ± 0.2777 and 0.4263 ± 0.2629 respectively,
p<0.05). FRAP values declined, from parasitemic patients (1.4619 ± 0.6565) compare to controls (2.4396 ± 0.8883, p<0.05),
particularly in the first and third trimester of gestation (p<0.05 and p<0.01 respectively). Finally, total erythrocyte protein
concentrations of women with malaria did not differ from that of the controls. Our results suggest an imbalance between oxidants
and antioxidants in pregnant women suffering from malaria, a situation which could lead to severe damage for either the mother
or the fetus. Therefore, further research should be done to assess the potential benefits of antioxidant supplementation for
the pregnant women suffering from malaria. 相似文献

Glutathione, the dominant intracellular thiol, plays an important protective role against oxidative stress. The accidental
findings of increased reduced glutathione level postprandially as compared to post absorptive level prompted the design of
present study. Reduced Glutathione levels were estimated in 50 healthy individuals in post absorptive and postprandial phase
by taking whole blood in ACD bulb. Mean postprandial reduced Glutathione (9.60±3.39 μmole/gm of Hb) is significantly increased
than mean postabsorptive level (5.53±0.88 μmole/gm of Hb; p<0.001). It also shows positive correlation (r=0.65) between these
two GSH levels. So present study suggests that post absorptive specimen collection is preferable over random or postprandial
as the former reflects the true basal level of reduced glutathione. 相似文献

In order to determine whether the screening of lipid profile is justified in patients with hypothyroidism we estimated serum
lipids in cases having different levels of serum TSH. 60 patients of hypothyroidism in the age group of 20 to 60 yrs were
studied for thyroid profile over a period of one year. On the basis of serum TSH level the cases were divided into three groups:
In the first group TSH concentration was 8.8±2.99 μlU/ml, 95% confidence interval (Cl) 8.8±1.07, whereas serum total cholesterol
and LDL-chol levels were 196±37.22 and 126±29.17 mg/dl respectively. The statistical analysis of these two groups showed a
significant correlation between raised TSH levels and serum total cholesterol and LDL-chol (P<0.05 & P<0.01) respectively.
We conclude that hypothyrodism is associated with changes in lipid profile. 相似文献

The antimicrobial activity of crude and methanol extract ofTerminalia bellerica dry fruit was tested by disc diffusion method, against 9 human microbial pathogens. Crude aqueous extract of dry fruit at
4 mg concentration showed zone of inhibition ranging from 15.5–28.0 mm.S. aureus was found to be highly susceptible forming highest zone of inhibition, suggesting thatT. bellerica was strongly inhibitory towards this organism. These pathogens were highly sensitive to the methanol extract forming 14.0
to 30.0 mm zone of inhibition suggesting that the methanol extract ofT. bellerica was more effective than crude extract against most of the microbes tested exceptE. coli (enteropathogen) andP. aeruginosa. The minimal inhibitory concentrations (MICs) of crude and methanol extracts were determined by broth dilution technique
which ranged from 300 to >2400 μg/ml and 250 μg to >2000 μg/ml respectively, indicating thatT. bellerica was highly effective againstS. aureus with lower MIC values. There were some biochemical alterations induced byT. bellerica. These results indicate thatT. bellerica dry fruit possesses potential broad spectrum antimicrobial activity. 相似文献

Thyroid stimulating hormone (TSH), Free Thyroxine (FT4) and Free Triiodothyronine (FT3) were assayed in 505 women of this region. 60 women had previous history of thyroid disease. The remaining 445 women formed
the “Disease free group”. A “Reference group” was obtained by excluding women with previous and present history of thyroid
dysfunction. Of the total 505 women examined 15.8% had thyroid dysfunction and 84.2% were euthyroid. 11.5% were hypothyroid
(9.5% sub-clinical) and 1.8% hyperthyroid (1.2% clinical). The geometric mean TSH for the total population was 2.65 μIU/ml.
It was significantly (p=0.025) lower in the reference population 2.17 μIU/ml. There was no significant difference in the FT3 and FT4 values between groups. 19% of women over 60 years had elevated TSH above 4.5 μIU/ml. The 2.5 and 97.5 percentiles of the
reference population was 1.1–5.2 μIU/ml. 6.1% of women in the reference group had TSH levels above the reference intervals.
Hypothyroidism particularly sub-clinical hypothyroidism is predominantly present amongst women in this iodine sufficient region.
Evaluation of thyroid status could help in early detection and treatment. 相似文献

Currently available method(s) for assaying pyrroline-5-carboxylate (P5C), an important intermediate metabolite of ornithine,
proline and glutamate metabolic pathways, are cumbersome or not sensitive enough for microanalysis. The present study involving
the synthesis of P5C followed by purity check, molecular mass (amu =113.1) determination by mass spectrometry and spectral
characterization of P5C-ninhydrin derivative (λ max: 510 nm) confirmed the authenticity of the preparation. Studies on the
effect of pH on spectral characteristics of P5C ninhydrin derivative demonstrated a significant change with respect to λ max
(620 nm) and several ∼ 12 fold increase in molar extinction coefficient (ε: 1.96 × 105) in alkaline conditions (pH:7.0–8.0) as compared to the reported Molar ε of 1.65 × 104 at max λ 510 nm in ethanolic solution. The modified method, with the improved sensitivity, is adopted for the assay of ornithine
amino transferase activity in WBC’s/platelets lysate(s) from human blood. 相似文献

In this study, differences in lipid levels amongst diabetics with and without complications were assessed to determine lipid
disorders that are associated with diabetic complications other than cardiovascular diseases. A Cross sectional study design
was employed. The study included 288 diabetics and 108 non diabetics with different types of complications such as hypertension,
nephropathy, neuropathy, and retinopathy. The mean serum total cholesterol was higher in patients with complications compared
to those without complications and the non-diabetic controls. The normotensive diabetic patients had the lowest total cholesterol
among the diabetic patients’ groups (4.65 ± 0.17 mmol/l) compared to the diabetics with hypertension (6.051 ± 0.20 mmol/l),
retinopathy (6.26 ± 0.29 mmol/l), neuropathy (5.80 ± 0.17 mmol/l) and nephropathy patients 5.74 ± 0.26 mmol/l (P < 0.05). The prevalence of dyslipidaemia among diabetic subjects was between 19.2 and 84.0%. The study shows that, in addition
to macrovascular complications, dyslipidaemia is common in type 2 diabetes mellitus patients with microvascular complications. 相似文献

WHO-Tropical Disease Research scheme highlighted the need for development of new anti-filarial drugs. Certain antibiotics
have recently been found effective against Wolbachia, co-existing symbiotically with filarial parasites. Inflammatory response
entails oxidative mechanism to educe direct anti-microbial effect. In the present study microfilariae were maintained in vitro
in medium supplemented with varying concentrations of tetracycline, doxycycline (20–100 μg/ml) or ciprofloxacin (50–250 μg/ml)
separately to find out any involvement of oxidative mechanism in the anti-filarial effect of these antibiotics. Loss of motility
of the microfilariae was measured after 48 h and correlated with the levels of MDA, nitric oxide and protein-carbonylation.
Significant loss of microfilarial motility was recorded with increasing concentration of tetracycline and doxycycline but
with ciprofloxacin the effect was not marked. Agents with high antifilarial activity revealed significant association with
oxidative parameters in a dose dependent manner. The result suggests that oxidative effect might be exploited to design novel
antifilarial drug candidate. 相似文献

The supply of oxygen is limited in certain intra abdominal conditions due to direct vascular invasion or inflammatory process, resulting in high lactate levels. Aim of this study was to find the predictive value of lactate levels in the peritoneal fluid (PF) and blood of patients with acute abdomen. The study comprised of fifty patients with acute abdominal conditions, admitted in emergency ward of tertiary care hospital, thirty patients were with surgical abdomen (group I) and twenty patients with non surgical abdomen (group II). Lactate was estimated in PF and blood on Blood Gas Analyzer (NOVA, M-7). The mean lactate levels in PF were significantly higher in group I as compared to group II (14.65 ± 1.195 vs. 5.92 ± 0.97 mmol/L, p < 0.001). There was no significant difference in blood lactate levels in both the groups. When PF and blood lactate levels were compared within groups, we found that PF levels were significantly higher than blood in group I (14.65 ± 1.195 vs. 3.85 ± 0.54 mmol/L, p < 0.001) but not in group II (5.92 ± 0.97 vs. 4.36 ± 0.95 mmol/L). Diagnostic value was obtained using ROC curve. Cut off values obtained for PF lactate, difference and ratio of PF and blood lactate (≥6.4 mmol/L, ≥3.3 and ≥2.1 respectively) are at very high degree of sensitivity and specificity. So it can be useful marker of surgical emergency in patients with acute intra abdominal pathology, especially in clinically ill patients or in whom physical examination is not yielding because of neurologic disorders or unresponsiveness. 相似文献
