Psoriasis is a chronic inflammatory, proliferative skin disease characterized by pathological skin lesions due to various
exogenous and endogenous factors. It is associated with a number of biochemical and immunological disturbances. Recently,
it has been suggested that increased reactive oxygen species (ROS) production and compromised function of antioxidant system
may be involved in the pathogenesis of this disease. In the present study, 90 psoriasis patients were selected. Disease severity
was assessed by psoriasis area severity index score and grouped as mild, moderate and severe (each group consists of 30 subjects)
and compared with 30 healthy controls. Serum levels of malondialdehyde, nitric oxide end products and the activities of antioxidant
enzymes such as erythrocyte-superoxide dismutase, catalase and total antioxidant status were investigated in these groups/subjects.
As compared to controls, we found severitywise significantly increased serum malondialdehyde, nitric oxide end products with
decrease in erythrocyte-superoxide dismutase activity, catalase activity and total antioxidant status in patients with psoriasis
suggesting worsening of the disease. It seems to be linked with the enhancement of Reactive Oxygen Species production and
decreased antioxidant potential in psoriasis. 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

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

The aim of this study was to develop an exercise protocol to simulate tennis matchplay on a 'category 2' surface. Match analyses were used to form the basis for the design of the protocol. The protocol involved playing against a tennis ball serving machine. Part A of the protocol comprised 92 min 46 s of simulated tennis matchplay; Part B consisted of continuous hitting to the point of 'volitional fatigue' or when the required hitting frequency for two consecutive ball feeds could no longer be maintained. Ten elite tennis players (5 males, 5 females) volunteered to participate in the study, which was performed on an indoor tennis court (Matchplay?, En-Tout-Cas)?. Their age, body mass and estimated maximal oxygen uptake were as follows: males, 21.7±1.0 years, 73.6±2.6 kg and 58.0±1.7 ml?·?kg?1?·?min?1, respectively; females, 21.9±1.3 years, 62.3±2.0 kg and 42.2±0.7 ml?·?kg?·?min?1, respectively (mean±). Heart rate, change in body mass and time to volitional fatigue were monitored. The heart rate responses of the participants to the simulated matchplay (range: 140-157 beats?·?min?1, 73-81% peak heart rate) were consistent with the results of previous studies, for 'actual' matchplay. This protocol was successful in simulating similar physiological responses in Part A to 'actual' matchplay on a 'category 2' surface, in a controlled environment; it was also a sensitive evaluation tool of skilled performance in Part B. The current protocol may be used as a baseline protocol for studying the influence of, for example, training and dietary intervention on performance. 相似文献

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

Skill development has been a major policy agenda in several countries and there is a lot of emphasis on the promotion of vocational education and training (VET) programmes. This paper investigates the labour market outcomes of the vocationally trained population in India using the data from a nationally representative survey on employment and unemployment. We find that a large section of the population in the age group 15–59 years does not have any kind of formal training. Among the VET holders, a large share is accounted for by non-formal trainees. Quite a high proportion of formal trainees in the workforce remain unemployed reflecting underutilisation of human resource. We also examine the extent to which individuals’ training matches their occupational levels and find that overall about two-thirds of the trainees are employed in occupations related to the field of training. Further, we compare the returns to general secondary and vocational education streams using the standard earnings function accounting for the sample selection bias. Our findings show that the relative returns to vocational education is higher than that to general secondary education. 相似文献

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

New findings on organization of blood cell cytoskeleton represent an exciting aspect of modem cell biology and hematology,
which is an interesting investigation to study diabetes. The present study was undertaken in 150 subjects. Out of these, 30
subjects were controls (Group I) and 30 were type-2 diabetics without any complication (Group II), while remaining 90 subjects
were type-2 diabetics with complication (Group III). We determined erythrocyte spectrin and hemoglobin glycosylation and also
estimated plasma lipid peroxide, nitric oxide and erythrocyte glutathione peroxidase activity to assess the status of oxidative
stress. There was a significant increase in spectrin (P<0.001) and hemoglobin (P<0.001) glycosylation in Group II and III
as compared to Group I and spectrin glycosylation was nearly three times more as compared to hemoglobin, whereas plasma levels
of lipid peroxide (P<0.001) as well as nitric oxide (P<0.001) were found to be significantly increased and GPx activity (P<0.001)
was significantly decreased in Group II and III as compared to Group I. However, it was also observed that spectrin (P>0.05)
and hemoglobin (P>0.05) glycosylation was not significantly different in Group II and III. In contrast, there was significant
rise in lipid peroxide (P<0.001), nitric oxide (P<0.001) and fall in GPx activity (P<0.001) in Group III when compared to
Group II. Increased erythrocyte protein glycosylation and oxidative stress is clearly evident from our study. However, to
understand the exact interplay between these two mechanisms, further studies are required. 相似文献

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