Thymoquinone is the active constituent ofNigella sativa, having antioxidant and anti-inflammatory actions. In present study, we have analyzed the effects of thymoquinone on doxorubicin (DOX) induced cardiotoxicity in mice. In this experiment, thirty mice (25–35 gm) were divided into five groups (Groups A, B, C, D, and E) each containing six animals. Normal saline was given to a control group (Group A) for 14 days. Cardiotoxicity was induced by DOX (15 mg/kg, i.p.) in Group B, once on the 13th day of the study, and Groups C and D also received DOX (15 mg/kg, i.p.) and were then treated with thymoquinone (10 and 20 mg/kg, b/w, p.o.), respectively, for 14 days. Group E was given only thymoquione (20 mg/kg b/w, p.o.). A blood serum marker (AST, ALT, CK-MB, and LDH) and oxidative stress marker (LPO, GSH, CAT, SOD, GPx, GR, and GST) were evaluated. Results revealed that serum enzyme marker like aspartate aminotransferase (AST), creatinine kinase-MB (CKMB), and lactate dehydrogenase (LDH) were significantly elevated in Group B as compare to Group A. Similarly, the oxidative stress marker lipid peroxidation (LPO) was also elevated in Group B while the antioxidant enzyme catalase, superoxide dismutase, glutathione peroxidase, glutathione reductase, and glutathioneS-transferase (CAT, SOD, GPx, GR, and GST) were also decreased in Group B. The treatment with thymoquinone 10 and 20 mg/kg resulted in a significant decrease in the serum marker and increase in the antioxidant enzymes. In this study, we have found that thymoquinone prevented DOX-induced cardiotoxicity by accelerating heart antioxidant defense mechanisms and down regulating the LPO levels towards normalcy in Groups C and D. The effect of doxorubicin increases the inflammatory cytokine (IL2) in Group B as compared to Group A, and it overcomes by the thymoquinone in Groups C and D. Thus, thymoquinone may have utility as a potential drug for cardiomyopathy.

Abstract Objectives This study examined the possible protective roles of exogenous glycine (Gly) and L-Arginine (l-Arg) against Diclofenac (DIC)-induced gastro-duodenal damage in rats. Methods Rats were divided into Group A (control), Group B (DIC group) and Groups C–F which were pre-treated for five days with Gly1 (250 mg/kg), Gly2 (500 mg/kg), l-Arg1 (200 mg/kg) and l-Arg2 (400 mg/kg), respectively, before co-treatment with DIC for another three days. Hematological, biochemical and histopathological analyses were then carried out. Results DIC produced significant (p<0.05) reduction in PCV (13.82%), Hb (46.58%), RBC (30.53%), serum total protein (32.72%), albumin (28.44%) and globulin (38.01%) along with significant (p<0.05) elevation of serum MPO activity (83.30%), when compared with control. In addition, DIC increased gastric H2O2 and MDA levels by 33.93 and 48.59%, respectively, while the duodenal levels of the same parameters increased by 19.43 and 85.56%, respectively. Moreover, SOD, GPx and GST activities in the DIC group were significantly (p<0.05) reduced in the stomach (21.12, 24.35 and 51.28%, respectively) and duodenum (30.59, 16.35 and 37.90%, respectively), compared to control. Treatment with Gly and l-Arg resulted in significant amelioration of the DIC-induced alterations although l-Arg produced better amelioration of RBC (29.78%), total protein (10.12%), albumin (9.93%) and MPO (65.01%), compared to the DIC group. The protective effects of both amino acids against oxidative stress parameters and histological lesions were largely similar. Conclusions The data from this study suggest that Gly or l-Arg prevented DIC-induced gastro-duodenal toxicity and might, therefore be useful in improving the therapeutic index of DIC.

This experiment was conducted to determine the effect of papaya leaf (Carica papaya) and kalo jeera (Nigella sativa) seeds powdered supplementation in drinking water as a growth promoter in broiler chickens. A total of 20 Cobb-500 broiler chicks (day-old) were purchased from local hatchery (Nourish Poultry and Hatchery Ltd.) and after seven days of acclimatization chicks were randomly divided into two groups, A (n=10) and B (n=10). The group A was kept as a control and not treated. The group B was supplemented with papaya leaf and kalo jeera powder with feed and water. Weekly observations were recorded for live body weight gain up to 5th weeks and hematological tests were performed at 35th day’s age of broiler to search for hematological changes between control (A) and treatment (B) groups. The initial body weight of groups A and B on 1st were 41.00±0.56 gm and 41.50±0.35 gm, respectively and after 35th day of experiment final body weight were 1470±57.35 gm and 1720±58.56 gm, respectively and economics of production were analyzed and found that net profit per broiler was Tk. 8.91 and Tk. 20.69, respectively. The treatment group B was recorded statistically significant (at 1% level) increased (17.00%) for live body weight than that of control group A. The hematological parameters total erythrocyte count (TEC), erythrocyte sedimentation rate (ESR) and hemoglobin (Hb) estimation value of treatment group shows significant difference, while hemoglobin estimation does not show significant difference from control group. The results suggest that better growth performance could be achieved in broilers supplemented with papaya leaf and kalo jeera seeds.

Aim To study the oxidative modification of red blood cell Cu,Zn superoxide dismutase (SOD) in patients with ischemic heart disease (IHD) in vivo and in vitro to substantiate the use of a new oxidative stress marker.Material and methods Red blood cell Cu,Zn SOD was measured by depression of nitrotetrazolium blue reduction by the superoxide anion generated in xanthine oxidase xanthine oxidation. Red blood cell Cu,Zn SOD was measured immunochemically. The biochemical study was performed in the control group (patients with low extremity fracture without known history of cardiovascular diseases and hyperlipidemia) and in groups of patients with acute myocardial infarction, stable angina, and decompensated heart failure. For evaluation of oxidative stress intensity in IHD patients, an empirical SOD oxidative modification coefficient (OMCSOD) was proposed, which is a Cu,Zn SOD activity / Cu,Zn SOD content ratio.Results The red blood cell Cu,Zn SOD activity was significantly decreased in all IHD groups compared to the control group. Furthermore, OMCSOD was also considerably decreased in IHD patients, which warrants the use of this biochemical index as an oxidative stress marker.Conclusion It was shown that the Cu,Zn SOD modification was induced by interaction of the enzyme molecules with a natural dicarbonyl, malonic dialdehyde, and OMCSOD can be used for evaluation of oxidative stress intensity in IHD patients.

Objective: To investigate the efficacy of curcumin oral supplementation (600 mg/day, Brainoil), a natural antioxidant compound, in Amyotrophic Lateral Sclerosis (ALS). Methods: Patients were randomized into two groups: Group A received placebo for 3 months, then Brainoil for the following 3 months, Group B took Brainoil for 6 months. The evaluations were conducted at basal (T0), after 3 months of double blinded Brainoil or placebo treatment (T1), and after the 3 month open-label phase (T2). Clinical evaluations and oxidative stress biomarkers, including oxidative protein products (AOPPs), ferric reducing ability (FRAP), total thiols (T-SH) and lactate, were evaluated, compared to a control group, during an incremental forearm exercise test. Results: Over the entire study Group B showed a stable score of the ALS-FRS-r which decreased in Group A (p<0.01), in parallel with a reduction of AOPPs (p<0.01) which was not detected into Group A. Also FRAP exercise values remained stable in Group B, while in Group A they were reduced without treatment at T1 (0.05<p<0.01), for then increase at T2 with introduction of therapy (p<0.05). In Group B T1>T0 exercise lactate was lower compared to Group A (p<0.01). Compared to controls, the whole ALS population showed a greater oxidative stress (p<0.001), those treated with curcumin (Group B) exhibiting decreased exercise AOPPs at T2 with values approaching those of controls. Conclusion: Although further studies are needed to confirm these data, treatment with curcumin shows encouraging results indicating a slight slowdown in disease progression, improving aerobic metabolism and oxidative damage, this also contributing to deepen knowledge into the pathogenic mechanisms of ALS.

Introduction: Cisplatin is one of the most widely used drugs for the treatment of various cancers but has oxidative tissue damage as one of its side effects. This study investigated the oxidative stress profile in some important body tissues following the co-administration of cisplatin (CIS) and resveratrol (RSV). Methods: Thirty-five adult female rats with an average body weight of 162g were divided into 5 groups (n=7) and used for this experimental study. Group A served as the normal control group and received distilled water only. Group B received only a single dose intraperitoneal injection of 10mg/kg CIS. Groups C, D and E were orally given 5, 10 and 20mg/kg of RSV respectively for 7 days, starting 24h after a single CIS dose intraperitoneal injection of 10mg/kg. Selected body tissues were harvested for oxidative stress profiling at the end of the experiment. Results: CIS significantly increased malondialdehyde levels and decreased glutathione, superoxide dismutase and catalase levels in all the tissues assessed (ovary, uterus, liver, kidney, pancreas, stomach and spleen) when compared to the normal control. The RSV treatment caused the reversal of these effects; malondialdehyde levels were significantly decreased, while glutathione, superoxide dismutase and catalase levels were significantly increased across all the examined tissues. Conclusion: RSV at different doses could be effective in the management of CIS-induced oxidative stress and lipid peroxidation across some body tissues. However, this effect may be dependent on the dose of CIS and RSV.

Background and objectives: Oxidative stress shows evidence of dysregulation in cirrhotic patients with hepatic encephalopathy (HE), although there are still controversies regarding the connections between oxidative stress and ammonia in these patients. The aim of this study was to evaluate the oxidative stress implication in overt HE pathogenesis of cirrhotic patients. Materials and Methods: We performed a prospective case-control study, which included 40 patients divided into two groups: group A consisted of 20 cirrhotic patients with HE and increased systemic ammoniemia, and group B consisted of 20 cirrhotic patients with HE and normal systemic ammoniemia. The control group consisted of 21 healthy subjects matched by age and sex. The activity of superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA) levels (lipid peroxidation marker), and ammoniemia were evaluated. Results: We found a significant decrease in SOD and GPx activity and also a significant increase of MDA levels in cirrhotic patients with HE as compared to the healthy age-matched control group (1.35 ± 0.08 vs. 0.90 ± 0.08 U/mL, p = 0.002; 0.093 ± 0.06 vs. 0.006 ± 0.008 U/mL, p = 0.001; and 35.94 ± 1.37 vs. 68.90 ± 5.68 nmols/mL, p = 0.0001, respectively). Additionally, we found significant correlations between the main oxidative stress markers and the levels of systemic ammonia (r = 0.452, p = 0.005). Patients from group A had a significant increase of MDA as compared with those from group B (76.93 ± 5.48 vs. 50.06 ± 5.60 nmols/mL, p = 0.019). Also, there was a compensatory increase in the activity of both antioxidant enzymes (SOD and GPx) in patients with increased systemic ammoniemia (group A), as compared to HE patients from group B. Conclusions: Our results demonstrated a significant decrease in antioxidants enzymes activities (SOD and GPx), as well as a significant increase in MDA concentrations, adding new data regarding the influence of oxidative stress in HE pathogenesis in cirrhotic patients.

Background: Apart from several well documented risk factors; oxidative stress may play an important role in the pathogenesis of myocardial infarction. Our study has been designed to investigate the pro-oxidant status in AMI patients who have no previous history of diabetes, hypertension and habit of smoking.Aims and Objectives: To measure the level of serum thiobarbituric acid reactive substances(TBARS) to assess the extent of oxidative damage in recently diagnosed cases of AMI and to look for any correlation between this stress marker and some of the lipid profile markers.Materials and Methods: A cross sectional study was conducted in a tertiary care hospital with 50 non-diabetic, non-hypertensive, non-smoker AMI patients of either sex as Cases and 50 age and sex matched healthy Controls. The biochemical parameters were measured by validated techniques.Results: Level of serum TBARS (4.78 ± 1.06 nmol/ml) has significantly increased (p<0.001) in cases with respect to control group(2.19±0.41 nmol/ml); a positive correlation between serum TBARS and LDL; a negative correlation between serum TBARS and HDL in cases.Conclusion: Our study indicates an increased oxidative stress in AMI patients even in absence of some high risk factors which are oxidative stress inducers by themselves. This evidence suggests that oxidative stress itself may play an important role in the pathogenesis of myocardial infarction. So, the oxidative stress marker may have the importance in early diagnosis of AMI. It also suggests the potential appropriateness of antioxidant therapy in the prevention of AMI.Asian Journal of Medical Sciences Vol.9(4) 2018 31-34

Introduction: Hepatotoxicity induced by anti-tuberculous medicine is known due to their oxidative stress. Ajwa dates may have a role to protect liver from oxidative stress Aims & Objectives: To assess the preventive effect of Ajwa date on hepatotoxicity induced by anti-tuberculous drugs in rabbits. Place and duration of study: Post Graduate Medical Institute, Lahore for three months, from May 2014 to July 2014. Material & Methods: Thirty rabbits were distributed into five groups. Rabbits of Group A and of B were fed on normal diet in form of pellets. Group C, D and E were provided diet containing one whole Ajwa date, flesh of one Ajwa date and powdered seed of one Ajwa date respectively in each 100 grams of diet throughout study. Group B, C, D and E were administered 50mg/kg isoniazid and 100mg/kg rifampicin orally for 14 days. Serum levels of liver enzymes Alanine transaminase (ALT), Aspartate transaminase (AST) and Alkaline phosphatase (ALP) and bilirubin were estimated on day 0 and 14. One way ANOVA followed by post hoc Tukey’s test and t-test were applied for statistical analysis using SPSS 20. Results: Baseline LFTs were normal in all groups. Significant hepatotoxicity was observed after 2weeks of INH and rifampicin administration in disease control group B (ALT 200.2±19.3 & ALP 231.0±21.3 IU/L, AST 139.0±22 & bilirubin 0.48±0.046mg/dl, (p value < 0.001) as compared to healthy control group A (ALT47.2 ± 6.7 & ALP78.2 ±5.0 IU/L, AST 43.0 ± 9.7, bilirubin 0.10± 0.00mg/dl). (p value < 0.001). Concomitant Ajwa intake during the same period resulted in an equipotent significantly similar improvement in LFTs in Groups C (whole date) ALT55.7 ± 4.7&ALP 91.5 ±5.0IU/L, AST, 59.0 ± 15.3 &bilirubin 0.09 ±0.02 mg/dl): D (flesh) ALT89.8 ± 6.3 & ALP111.3 ±9.4 IU/L, AST73.7 ± 8.3 & bilirubin0.12± 0.04 mg/dl & E (seed powder) ALT85.8 ± 8.6 IU/L &ALP 92.8 ±11.4 IU/L, AST57.5 ± 5.3 & bilirubin 0.12 ±0.04 mg/dl) versus group B (p value < 0.001). and near normalization of liver function close to that of healthy control group Conclusion: Co-administration of Ajwa date whole fruit, flesh and seed powder are equipotent and effective in preventing isoniazid and rifampicin induced hepatotoxicity.

Aim. To investigate the role of a novel oxidative stress marker, thiol/disulphide homeostasis, in patients diagnosed with acute appendicitis (AA).Methods. In this study, seventy-one (43 male and 28 female) patients diagnosed with AA and 71 (30 male and 41 female) healthy volunteers were included. Age, gender, body mass index (BMI), haemoglobin (Hb), white blood cell (WBC), c-reactive protein (CRP), and thiol/disulphide homeostasis parameters (native thiol, total thiol, disulphide, disulphide/native thiol, native thiol/total thiol, and disulphide/total thiol ratios) were compared between the groups. Thiol/disulphide homeostasis was determined by a newly developed method by Erel and Neselioglu.Results. The native thiol, total thiol, and the native thiol/total thiol ratio levels were statistically significantly decreased in the AA compared with the control group (p<0.001). Disulphide level and the ratios of disulphide/native thiol and disulphide/total thiol were higher in the AA group than in the control group (p<0.001). There was a negative correlation of CRP with native thiol, total thiol, and native thiol/total thiol ratio while there was a positive correlation of CRP with disulphide/native thiol and disulphide/total thiol in the AA group. In the stepwise regression model, risk factors as disulphide/native thiol (OR = 1.368;p=0.018) and CRP (OR = 1.635;p=0.003) were determined as predictors of perforated appendicitis compared to the nonperforated group.Conclusion. This is the first study examining the thiol/disulphide homeostasis as a diagnostic aid in AA and establishing thiol/disulphide homeostatis balance shifted towards the disulphide formation due to thiol oxidation. Further studies are needed to optimize the use of this novel oxidative stress marker in AA.


OBJECTIVE: To investigate the anti-oxidative and anti-nephrotoxic effects of Resveratrol in cisplatin induced nephrotoxic albino Wistar rats. METHODS: This quasi-experimental study was performed at Isra University, Hyderabad, Pakistan. Thirty male albino Wistar rats were divided into three groups: group-A (control), group-B (cisplatin) and group-C (cisplatin+Resveratrol). Biochemical [serum urea, creatinine and glutathione peroxidase (GPX)] and renal histomorphology was performed in all groups after 21 days of treatment. RESULTS: Difference in mean pre- and post-experimental body weight was observed in all three groups. Mean body weight decreased from 241.7±8.5 gm to 196.50±9.34 gm and from 237±7.4 gm to 207.2±6.56 gm in group-B and group-C respectively. In group-A; mean serum urea was 22.7±2.66 mg/dl, serum creatinine was 0.45±0.05 mg/dl and serum GPX was 1.44±0.13 ηg/ml. In group-B; mean serum urea level was 51±3.65 mg/dl, mean serum creatinine was 0.78±0.05 mg/dl and serum GPX was 0.85±0.11 ηg/ml. In group-C, mean serum urea level was 32.8±1.45 mg/dl, serum creatinine level was 0.41±0.09 mg/dl and serum GPX was 1.53±0.08 ηg/ml. In group-A, renal structure was intact, marked changes were observed in renal histology of group-B while group-C displayed less glomerular damage. The mean distance between visceral and parietal layers of Bowman’s capsule was 69.34±0.87 µm in group-A, 216.5±1.32 µm in group-B while 102.22±1.65 µm in group-C. Areas of peritubular fibrosis and congestion were observed in groups B and C but less prominent in group-C compared with group-B. CONCLUSION: Resveratrol therapy is a potent anti-nephrotoxic regime showing promising results in chemotherapy induced nephrotoxicity and oxidative stress.
