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.

Background: Consumption of a healthy diet abundant in antioxidant and anti-inflammatory phytochemicals, offers an effective and least expensive way to prevent neurodegeneration. Herein, the role of Tetracarpidium conophorum (African walnut) enriched diet in chronic stress-induced cerebellar neuropathology was investigated Methodology: Twenty-one male Wistar rats were used for this investigation. Rats were randomly assigned into three groups (A, B, and C), each consisting of 7 rats (n = 7). Group A (Control group) were fed control diet; group B rats were subjected to different chronic unpredictable stressors (CUS) + control diet for 21 days, while group C rats were subjected to CUS + Walnut-enriched diet for 21 days. Serum corticosterone levels, the expression level of antioxidant and inflammatory markers, and cytoarchitectural changes in cerebellum were assessed by enzyme-linked immunosorbent assay (ELISA) immunohistochemistry methods. Results: The walnut-enriched diet prevented astrogliosis, modulated serum corticosterone expression, and tumor necrotic factor-α in the cerebellum. The walnut-enriched diet also caused an improvement in the antioxidant profile, indicating that it suppressed chronic unpredictable stress-induced perturbations. Conclusion: Our results suggest that African walnut exerts protective effects against oxidative stress-driven dysfunction by reducing serum corticosterone levels, modulating oxidative stress pathways, and preventing neuronal morphological damage in the cerebellum.

Introduction: Cyclophosphamide is one of the alkylating chemotherapeutic drug used in cancer patients that has antifertility effects on female gonads. Ocimum basilicum is a natural herb rich in polyphenols and is known to improve fertility. Aims & Objectives: The study was designed to evaluate the role of natural herb, Ocimum basilicum extract, as a preventive agent against ovarian follicular toxicity induced by cyclophosphamide. Place and duration of study: This experimental study was performed in the Department of Anatomy, Shaikh Zayed Postgraduate Medical Institute, Lahore. The duration of study was 8 months. Material & Methods: 45 female albino rats were divided equally in control group A, experimental group B and group C each contained 15 rats. Group A rats received single dose of 150 mg/kg normal saline intraperitoneally on 8th day of experiment, while group B was given single intraperitoneal dose of 150 mg/kg cyclophosphamide at day 8 of experiment. Group C rats were pretreated with methanolic basil (Ocimum basilicum) seeds extract for 7 days followed by single intraperitoneal dose of 150 mg/kg cyclophosphamide at day 8 of experiment. All the rats were dissected 48 hours after the last dose. Results: Graafian follicles were atrophied showing atretic granulosa cells in group B when compared with control group A with p value <0.001. However, significant improvement in status of Graafian follicles was observed in group C, when compared with group B with p value <0.025. Conclusion: This study depicts that basil seeds extract can prevent the cellular toxicity in Graafian follicles caused by cyclophosphamide treatment. So the use of basil seeds during chemotherapy can significantly limit its toxic effects on Graafian follicles.

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.

Background: Thyroxine has shown beneficial effects on intelligence, learning, and memory process in patients of congenital hypothyroidism. Minocycline has been used in clinical practice for various indications and reported to have anti-thyroid effects. This study was specifically designed to observe the role of thyroxine on minocycline induced damage to thyroid gland. Methods: This experimental study was undertaken at Anatomy department of BMSI, JPMC, Karachi, for eight weeks, from October to November 2019. Thirty adult (10-12 months) male guinea pigs, weighing from 450-650 gm were obtained and divided into 3 groups. Group A served as control, group B was given Minocycline 0.02mg/gram/day once daily and group C was administered Minocycline in similar amount as group B along with thyroxine 0.5µg/gram/day for the same duration. Dosing was continued for 8 weeks, at the completion of which all the animals were sacrificed. Thyroid gland was processed and tissue sections were stained with Haematoxylin and Eosin for morphology. Results: The absolute weight of thyroid gland was significantly increased (p<0.001) in minocycline treated group B animals compared to the control animals, whereas substantial decrease (p<0.01) in absolute weight of thyroid gland was witnessed in group C in comparison to group B animals. The follicular cells showed hypertrophy and shrinkage of colloid in the thyroid follicles. These changes were prevented when animals were co-administered with thyroxine and minocycline in Group C. Conclusion: Concomitant administration of thyroxine with the antimicrobial drug minocycline showed protective effects of thyroxine on Minocycline induced damage to thyroid gland of animals.

Twenty-four clinically Sarcoptes-infested dogs were randomly enrolled into three groups (groups A, B, and C), 8 dogs in each group. Group A was treated with ivermectin + Calendula officinalis flower extract (CFE). Group B was treated with ivermectin + N-acetyl cysteine (NAC) (standard positive controls), while group C (negative control) was treated with ivermectin alone. Another eight healthy dogs were used as healthy controls (group D). By day 28 after therapy, the dogs treated adjunctly with CFE as well as with N-acetyl cysteine revealed significant () amelioration of the altered markers of oxidative stress towards normalcy. The dogs of these groups also revealed significant () amelioration of apoptotic leukocytes towards normalcy, and values were comparable to those of the healthy controls. While by day 28 after therapy, ivermectin alone treated dogs could not achieve comparable values to those of the healthy controls. The dogs treated adjunctly with CFE and N-acetyl cysteine also revealed faster parasitological as well as clinical cure rate as compared to the ivermectin alone treated dogs. In conclusion, CFE has remarkable antioxidant and antiapoptotic potential and can constitute a potential adjunctive remedy with miticide for the therapeutic management of canine sarcoptic mange.

Contagious ecthyma (CE) is a highly contagious viral skin disease that is typically self-limited. Treatment options include topical antiseptics, such as KMNO4, local antibiotics and systemic antibiotics to prevent secondary skin infections. The aim of this study was to compare the effectiveness of the lincomycin/spectinomycin combination and dexpanthenol (Dxp) in goat kids with CE. The study was conducted at a Saanen dairy goat farm in Bursa, Turkey. The owner of the goat herd inquired at the veterinary hospital about the appearance of granulomatous lesions on the muzzles of goat kids. In this study, 24 goat kids (1-month-olds) were used. All animals were subjected to the same conditions. Blood and papule samples were taken from the animals’ lips, muzzle and buccal for virological analysis. Swab samples were taken from the lesions for culture and antibiogram. The animals were divided into three groups. Lesions were clinically scored at days 1, 7 and 15 according to a modified previously used scoring system. Goat kids were equally grouped on the basis of lesions on the buccal, lips and muzzle. The animals in group A received 15 mg/kg lincomycin/spectinomycin combination (Lypectin®, Vilsan) intramuscularly for 3 consecutive days, group B received 20 mg/kg Dxp (Bepanthen® amp, Bayer, Germany) intramuscularly for 3 consecutive days, and group C received 0.9% NaCl (2 ml), the control treatment. Clinical recoveries were almost equal in all groups, but by day 14, group A showed better recovery than group B and group C. Both study groups also showed better results than the control group for all days. In conclusion, we believe that the lincomycin/spectinomycin combination or dexpanthenol can be useful in the supplementary treatment of CE in goat kids..

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.

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.
