Objective. To evaluate the involvement of proinflammatory and oxidative stress markers in gingival tissue in individuals with chronic periodontitis.Subject and methods. Eighteen subjects were divided in two groups: experimental (age52.9±5.0) and control (age51.1±9.6). The activities of enzymatic antioxidants such as catalase, glutathione peroxidase (GPx), glutathione S-transferase (GST), glutathione reductase, nonenzymatic antioxidants: total glutathione and reduced glutathione, oxidized glutathione (GSSG), thiobarbituric acid reactive substances (TBARS), and myeloperoxidase activity (MPO) were evaluated in gingival tissues from interproximal sites. Statistical differences between groups were determined by independent Studentttest andP<.05.Results. Individuals with periodontal disease exhibited a significant increase in the activities of MPO, GPx, GST, and also in TBARS and GSSG levels in gingival tissue compared to the control group (P<.05).Conclusion. The results of the present work showed an important correlation between oxidative stress biomarkers and periodontal disease.

Background: Diabetes Mellitus (DM) is a progressive metabolic disorder. Objective: The aim of this study was to investigate the relationship between antioxidant and oxidative stress markers in the saliva of patients with type 2 DM and a healthy control group. Methods: In this study, 20 patients with diabetes and 20 healthy individuals were evaluated. Salivary antioxidants markers consisted of total antioxidant capacity (TAC), uric acid (UA), peroxidase and catalase. Oxidative stress markers included total oxidant status (TOS), malondealdehyde (MDA) and total thiol (SH). Sialochemical analysis was performed with spectrophotometric assay. All the statistical analyses were conducted using STATA software. Results: TAC decreased significantly in patients with diabetes. Although salivary UA and peroxidase were lower in patients with diabetes compared to the control group, the difference was not significant. Salivary catalase in patients with diabetes was significantly lower than that in the control group. MDA and TOS exhibited significantly higher levels in type 2 DM. SH levels were slightly higher in DM. Conclusions: According to the results of the present study, there were some changes in the salivary levels of some antioxidants and oxidative stress markers in patients with type 2 DM and could be measured as an indicator of serum changes..

CAD is recognized as a multifactorial disease that is influenced by environmental and genetic factors. This study aimed to evaluate the levels of lipid parameters, oxidative stress and antioxidant markers in subjects with CAD compared to their age & sex matched controls and to analyze the relationship between atherogenic Index and oxidative stress among them 62 clinically proved CAD patients and 62 healthy age and sex matched subjects without CAD were selected for this study. 5 ml of fasting venous blood was collected from all the subjects and investigations such as FPG, lipid profile, oxidative markers Malondialdehyde (MDA), F2 isoprostanes (F2iso) and antioxidants glutathione S-transferase (GST), superoxide dismutase (SOD), vitamin-C, vitamin-E were performed. This study showed that levels of lipid parameters total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-c) and AI were significantly higher whereas high density lipoprotein cholesterol (HDL-c) were significantly low in CAD patients compared to normal controls. Oxidative stress markers MDA and F2 Isoprostanes level were significantly high, whereas enzymatic antioxidants GST and SOD and non-enzymatic antioxidants Vitamin-C and Vitamin-E levels were significantly low in CAD patients. Oxidative stress markers were found to significantly influence the AI. Results of this study showed that oxidative stress markers F2iso and MDA and antioxidants GST, VIT-C and VIT-E are found to influence the atherogenic index significantly.

Abstract Background Oxidative stress is involved in many diseases including diabetes and cancer. Numbers of studies have suggested its involvement in the pathogenesis of periodontal diseases. The aim of this study was to evaluate the levels of biochemical parameters and oxidative stress markers in plasma of healthy and chronic periodontitis patients. Methods One hundred thirty subjects were divided into two groups; patients (mean age = 42 ± 13.6 y.o) and control (mean age = 44.8 ± 12.6 y.o). Patients and healthy subjects were free from any infection, coronary or heart disease, diabetes or liver failure. Total cholesterol, LDLc, HDLc, Triglycerides (TG), creatinine, uric acid (UA), glucose and urea levels as well as the activities of enzymatic antioxidants such as catalase, glutathione reductase (GR) and total antioxidant capacity (TAOC), were measured in plasma samples using colorimetric assays. Statistical differences between groups were determined by Student’s t-test and p ≤ 0.05 was considered as significant. Results Periodontitis patients exhibited significant decrease in the activities of catalase, TAOC, GR and TG, cholesterol, LDLc, glucose, HDLc, uric acid levels in plasma samples in comparison with healthy subjects. However, no statistically significant differences in the levels of creatinine and urea were observed between the two groups. Conclusion The reduction of plasma antioxidant activities (Catalase, TAOC, GR) may have a role in the pathogenesis of periodontal diseases. Our findings suggest a decrease in the host capacity to control the damage caused by oxidative stress. Therefore, therapeutic strategies, aiming at modulating the oxidative stress could be considered as potential tools for the prevention or treatment of periodontal diseases and their potential systemic effects on the general health.

Free radicals play an important role in the pathogenesis of tissue damage in many clinical disorders, including atherosclerosis. This study was to investigate lipids and oxidative stress markers among women with 50 healthy non-pregnant compare with 50 healthy pregnant and 50 pregnancy-induced hypertensive subjects and correlate with cardiac troponin I (cTnI) and troponin T (cTnT). The level of plasma thiobarbituric acid reactive substances (TBARS), cTnI and cTnT levels significantly increase in pregnancy-induced hypertension compare with other groups. The level of lipids significantly altered in pregnancy-induced hypertension. Conversely, the activities of both enzymatic and non-enzymatic antioxidants were significantly decreased in pregnancy-induced hypertension compared to non-pregnant and healthy pregnant. Our data suggest that there is an imbalance between lipoperoxidation and antioxidants levels during pregnancy and preeclampsia. Serum cTnI and cTnT are elevated in women with pregnancy-induced hypertension indicating some degree of cardiac myofibrillar damage and cardiac dysfunction.Online: 11 July 2010DOI: http://dx.doi.org/10.3329/bmrcb.v36i1.4806Bangladesh Med Res Counc Bull 2010; 36: 4-9

Background. Treating nonalcoholic fatty liver disease (NAFLD) is considered one of the public health priorities in the past decade. So far, probiotics have represented promising results in controlling the signs and symptoms of NAFLD. However, attempts to find the ideal probiotic strain are still ongoing. The present study is designed to find the best strain amongst suitable probiotic strains according to their ability to ameliorate histopathological and oxidative stress biomarkers in hepatic steatosis-induced rats. Methods. Initially, four probiotics species, including Lactobacillus (L.) acidophilus, L. casei, L. reuteri, and Bacillus coagulans, were cultured and prepared as a lyophilized powder for animals. The experiment lasted for fifty days. Initially, hepatic steatosis was induced by excessive ingestion of D-fructose in rats for eight weeks, followed by eight weeks of administering probiotics and D-fructose concurrently. Forty-two six-week-old male rats were alienated to different groups and were supplemented with different probiotics ( 1 ∗ 10 9   CFU in 500 mL drinking water). After eight weeks, blood and liver samples were taken for further evaluation, and plasma and oxidative stress markers corresponding to liver injuries were examined. Results. Administration of probiotics over eight weeks reversed hepatic and blood triglyceride concentration and blood glucose levels. Also, probiotics significantly suppressed markers of oxidative stress in the liver tissue. Conclusions. Although some of the single probiotic formulations were able to mitigate oxidative stress markers, mixtures of probiotics significantly ameliorated more symptoms in the NAFLD animals. This enhanced effect might be due to probiotics’ cumulative potential to maintain oxidative stress and deliver improved lipid profiles, liver function markers, and inflammatory markers.

Background: Reactive aldehydes are involved in diseases associated with oxidative stress, including diabetes. Human salivary aldehyde dehydrogenase (hsALDH) presumably protects us from many toxic ingredient/contaminant aldehydes present in food. Objective: This study aimed to probe the activity of hsALDH in patients with diabetes and than to correlate it with various oxidative stress markers in the saliva. Methods: The saliva samples were collected from total 161 diabetic patients from Rajiv Gandhi Centre for Diabetes, Jawaharlal Nehru Medical College (JNMC), AMU, Aligarh, (India). HsALDH activity and markers of oxidative stress [8-hydroxydeoxyguanosine (8-OHDG), malondialdehyde (MDA) and advanced glycation end products (AGEs)] were measured in the saliva samples. Results: Patients with early stage of diabetes had higher activity of hsALDH when compared with the control group. As the history of diabetes increases, the activity of the enzyme decreases and also higher oxidative stress markers (8-OHDG, MDA and AGEs) are detected in the saliva samples. Negative significant correlation between hsALDH activity and oxidative stress markers were observed (p <0.0001). Conclusion: The activity of hsALDH increases in early stages of diabetes most probably to counter the increased oxidative stress associated with diabetes. However, in later stages of diabetes, the activity of the enzyme decreases, possibly due to its inactivation resulting from glycation.

Objective: The antihyperglycemic and antioxidative effects of L. microphyllum were evaluated by using in vivo methods in normal and alloxan induced diabetic rats.Methods: Diabetes was induced in Sprague Dawley rats by injecting alloxan through intravenous (i. v) at a dose of 100 mg/kg of body weight. Aqueous extract of L. microphyllum at different doses (400, 200 and 100 mg/kg of body weight) was administered orally (orogastric intubation) for 14 d. Blood glucose and oxidative stress markers were measured. Hematoxylin and eosin staining method were used to examine the pancreatic tissues.Results: At the 14 d interval, fasting blood glucose showed a reduction in serum glucose levels in animals pretreated with L. microphyllum compared with alloxan alone treated group. Oxidative stress was noticed in rat’s pancreatic tissue as evidenced by a significant decrease in glutathione level, glutathione reductase, glutathione-S-transferase, and catalase activities. Malondialdehyde showed a significant increase compared to the normal saline-treated control group. Serum biochemistry and oxidative stress markers were consistent with the pancreatic histopathological studies. Treatment of diabetic rats with L. microphyllum at a dose level of 100, 200 and 400 mg/kg body weight leaves extract for 14 d significantly prevented these alterations and attenuated alloxan-induced oxidative stress (P<0.05).Conclusion: The results of the present study indicated that the antihyperglycemic potential of L. microphyllum might be ascribable to its antioxidant and free radical scavenging properties. Thus, it is concluded that L. microphyllum may be helpful in the prevention of diabetic complications associated with oxidative stress.

AbstractIncreasing evidence points towards the role of mitochondrial functioning, energy metabolism, and oxidative stress in migraine. However not all previous research has been conclusive and some mitochondrial function/oxidative stress markers have not yet been examined. To this end, alpha-lipoic acid (ALA), total thiols, total plasma antioxidant capacity (TAC), lipid peroxide (PerOx), oxidised LDL (oxLDL), HbA1c and lactate were determined in the serum of 32 higher frequency episodic migraineurs (5–14 migraine days/ months, 19 with aura, 28 females) in this cross-sectional study. The majority of patients had abnormally low ALA and lactate levels (87.5% and 78.1%, respectively). 46.9% of the patients had abnormally high PerOx values, while for thiols and TAC over one third of patients had abnormally low values (31.2% and 37.5%, respectively). 21.9% of patients had abnormally low HbA1c and none had an HbA1c level above 5.6%. oxLDL was normal in all but one patient. This study provides further evidence for a role of oxidative stress and altered metabolism in migraine pathophysiology, which might represent a suitable therapeutic target. ALA, being too low in almost 90% of patients, might represent a potential biomarker for migraine. Further research is needed to replicate these results, in particular a comparison with a control group.This study is part of the trial registration: ClinicalTrials.gov: NCT03132233, registered on 27.04.2017, https://clinicaltrials.gov/ct2/show/NCT03132233.

Statins provide greater protection than predicted from just cholesterol-lowering effects, which is possibly mediated by other pleiotropic actions. This study aimed to examine the possible interaction effect of asthma on lipid profiles and evaluate the effect of rosuvastatin treatment on asthma. The animals were assigned into (1) control, (2) asthmatic, (3) hyperlipidemic, (4) asthmatic-hyperlipidemic, (5) rosuvastatin (40 mg/kg/day intraperitoneally, for 3 weeks)-treated asthmatic, (6) rosuvastatin-treated hyperlipidemic and (7) rosuvastatin-treated asthmatic-hyperlipidemic groups. Tracheal responsiveness to methacholine and ovalbumin, total and differential WBC (white blood cell) counts, and oxidative stress markers in bronchoalveolar lavage fluid (BALF) were evaluated. In the asthmatic and asthmatic-hyperlipidemic groups, tracheal responsiveness to ovalbumin, total WBC count, numbers of eosinophils, neutrophils, and monocytes were higher than the control group (p<0.001). A left-ward shift in the concentration-response curves to methacholine, an increase in nitrite and malondialdehyde concentrations, and a decrease in total thiol content, superoxide dismutase and catalase activities were also observed in the asthmatic and asthmatic-hyperlipidemic groups compared to control group (p<0.01 to p<0.001). Beyond lipid-lowering effect in the treated hyperlipidemic and asthmatic-hyperlipidemic groups, rosuvastatin treatment decreased tracheal responsiveness to methacholine, reduced total WBC count, the numbers of eosinophils, neutrophils, and monocytes, as well as decreased malondialdehyde concentration, and increased total thiol content, superoxide dismutase and catalase activities in treated asthmatic and asthmatic-hyperlipidemic groups (p<0.05 to p<0.001). The improving effect of rosuvastatin on asthmatic and asthmatic-hyperlipidemic animals was shown due to pleiotropic mechanisms including the effect on airway hyperresponsiveness, lung inflammation, and oxidative stress.
