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.

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.

Aim: This study was aimed to evaluate the effect of methanol extract of Napoleonae imperialis leaves against methotrexate renal damage in albino rats. Methodology: Thirty (30) male albino rats of mean weight 130 g were used for this study. The animals for the study were grouped into five (5) of six (6) rats each. Group A (normal control) received feed and water only and Group B (positive control) was induced with methotrexate without treatment. Test groups (C and D) were orally given 250 mg and 500 mg/kg b.wt of leaves extract, and group E was orally given the extract only (500 mg/kg b.wt) respectively for 14 days. All the rats used in this study were initially subjected to renal damage using 0.5 ml/kg of methotrexate except the normal control group. The rats were sacrificed after 14 days and the blood samples were collected for biochemical analysis, Results: From the result obtained, there was a significant (p< 0.05) decrease in the groups that received 250 mg/kg and 500 mg/kg b.wt of the plant extract in (Urea, Creatinine and Na+), and a significant increase (p< 0.05) in K+ and Cl-. Also there was a significant (p< 0.05) decrease in (Urea, Creatinine, and Na+) in comparison with the control groups and the group that received the extract only (500 mg/kg b.wt), and a significant increase (p< 0.05) in (K+ and Na+). Conclusion: The study indicates that the methanol extract of Napoleonae imperialis leaves may have exerted renal functioning effects in albino rats, and may also be used pharmacologically in the management of organ toxicity.

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.

Aim Angiogenesis plays an important role in the pathogenesis of endometriosis. Thus, the inhibition of angiogenesis may prevent endometriosis. Bevacizumab is a recombinant humanized monoclonal antibody against VEGF. The aim of this study is to investigate the efficacy of anti-VEGF therapy on the prophylaxis and treatment of endometriotic foci in a rat model. Methods This experimental study is prospective, randomized, and placebo-controlled. Thirty-six Wistar-Albino female rats were divided into 3 groups. Experimental endometriosis was induced by the implantation of autologous endometrial tissue. The bevacizumab administration route was intraperitoneal. Group A was the prophylaxis group; Group B was the treatment group, and Group C was the control group. The volumes of the implants as well as their VEGF and Ki-67 immunohistochemical staining are main outcome measures. Results The volumes of the lesions were smaller in Group A than Group C [P<.05]. The volumes of endometriotic foci in Group B were smaller than in Group C [P<.05]. Bevacizumab caused regression and atrophy of the endometriotic lesions. After the treatment the histopathologic and immunohistochemical scores in Group B were less than before treatment and less than the scores in Group C. Conclusions Bevacizumab treatment had a regressive effect on the endometriotic implants. As an anti-VEGF agent, bevacizumab has beneficial effects on the prophylaxis and treatment of endometriosis.

Abstract Introduction: Calabash chalk is a naturally occurring mineral, chiefly composed of fossilized sea shells. It is prepared from clay and mud mixed with other ingredients, including lead, arsenic, sand and wood ash. Clay consumption is correlated with pregnancy, and also to eliminate morning sickness in women. The aim of this study is to evaluate the effects of calabash chalk on the ovarian function in adult female Wistar rats. Methods: Eighteen (18) adult female Wistar rats. Group A served as the control group, group B received 40 mg/kg body weight of Non-salted calabash chalk while group C received 40 mg/kg body weight of Salted calabash chalk for 14 days. On day 15, the animals were sacrificed for histological and biochemical examination. Results: Results showed a significant (P< 0.05) reduction in follicle stimulating hormone (FSH) levels of the treatment groups when compared with the control group and an increase in luteinizing hormone (LH) levels of the treatment groups when compared with the control group. Histological examination of the ovaries showed severe deterioration of the ovarian follicles, necrosis and follicular atresia. Conclusion: Calabash chalk is toxic to ovarian function. These alterations have been shown to be the leading cause ofinfertility in female rats. Hence, proper monitoring, education, and regulation of the product is needed.

The aspect of treatment of autistic behaviour was investigated using valproic acid rat model of pregnant female rats. Two main groups (10 male rats/group) were treated for 6 days and then divided into six subgroups. The first group of normal rats was divided into three subgroups: (A) – control group, (B) – treated with camel milk (CAM; 2 mL/p.o) and (C) – treated with leptin (1000 µg/kg i.p) twice daily. The second group of autistic rats was randomly distributed into four subgroups as follows: (D) – positive control (autistics rats), (E) – treated with CAM, (F) – treated with a moderate dose of leptin and (G) – treated with a higher dose of leptin. Autistic behaviours of male offspring were checked by grooming and elevated pulz maze tests. Valproic acid (VPA)-induced autistic rats showed severe changes in oxidative stress markers, neurotransmitters and inflammatory cytokines, besides genotoxic manifestation of expression of tumour necrosis factor (TNF)-α, Bax and caspase-3. Leptin or CAM alone showed no signs of toxicity. CAM showed pronounced improvement in control rats than control itself. Leptin or CAM treatment of autistic animals showed a significant improvement of all measured parameters and genetic expression values. The improvement was pronounced in animals treated with CAM. These results suggest that CAM is a potential therapeutic candidate for autism via regulation of inflammatory and apoptotic pathways. Leptin plays an essential role in alleviation of autistic behaviour through antioxidant effects.

Background. To explore influence of continuous illumination, luzindole, and Tamoxifen on incidence of scoliosis model of rats.Methods. Thirty-two one-month-old female rats were rendered into bipedal rats. The bipedal rats were divided into 4 groups: group A by intraperitoneal injection of luzindole and continuous illumination; group B by intraperitoneal injection of luzindole only; group C by intraperitoneal injection of luzindole and oral administration of Tamoxifen; and group D by intraperitoneal injection of equivalent saline. Radiographs were taken at 8th week and 16th week, and incidence and the Cobb angles of scoliosis were calculated. At 16th week, all rats were sacrificed. Before the sacrifice, the levels of calmodulin were measured in each group.Results. At 8th week, scoliosis occurred in groups A and B, with an incidence of 75% and 12.5%, respectively, while rats in group C or D had no scoliosis. At 16th week, scoliosis incidences in groups A and B were 57% and 62.5%, respectively. No scoliosis occurred in group C or D. Calmodulin in platelets in group B was significantly different, compared with groups A and D. There was no significant difference in calmodulin in platelets in groups B and C.Conclusion. By intraperitoneal injection of luzindole in bipedal rats, scoliosis rat models could be successfully made. Under light, incidence of scoliosis may be increased at an early period but it is reversible. Tamoxifen can suppress natural process of scoliosis.

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.

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.

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.
