The World Health Organization (WHO) has shown concern about the burden of tuberculosis in the developing countries. Even though rifampicin is an effective drug in the management of tuberculosis, it has been documented to have some toxic effects in humans. Therefore, this study intends to investigate the modulatory effect of vitamins C and E on the hepatotoxicity, sperm quality and brain toxicity of Rifampicin. Forty Wistar albino rats were used, 10 animals per group. Group 1 animals received 0.3 mL of distilled water, the Group 2 animals received the therapeutic dose of rifampicin, Group 3 animals received therapeutic doses of rifampicin plus vitamin E, while Group 4 received therapeutic doses of rifampicin and vitamin C. The administration was performed orally during three months; the animals were sacrificed by cervical dislocation at the end of that period. Blood samples were collected and liver function and lipid profile was analyzed using fully automated clinical chemistry device. The liver, brain and reproductive organs underwent histopathological examination. Sperm samples were collected from the epididymis to achieve count and motility and morphological analysis. Results showed rifampicin alone to raise (p < 0.05) liver function enzymes (Aspartate amino transferase [AST], Serum alanine amino transferase [ALT] and Total Bilirubin) when compared with controls. While the vitamin E treated group showed remarkable protection, the vitamin C treated group showed questionable protection against the rifampicin induced liver damage. Sperm count results showed an important (p < 0.05) increase in the sperm quality in vitamin E and C treated groups. However, the vitamin E plus Rifampicin treated group showed increased lipid peroxidation. The histopathological findings revealed structural damages by rifampicin in liver, brain and epididymis while some remarkable architectural integrity was observed in the antioxidant-treated groups. It can be concluded that vitamin E or C improved sperm quality and protected against the brain damage caused by rifampicin. Moreover, vitamin E demonstrated remarkable hepatoprotection against rifampicin induced damage while vitamin C shows a questionable hepatoprotection.

Objective: To evaluate the effect of cefepime on hematological changes, immunological disorders and hepatic oxidative damage in rats experimentally infected with E.coli ATCC 25922. Design: Randomized controlled experimental study. Animals: Thirty-two adult male albino rats weighting150-200 g. Procedures: Rats used for this study were randomly assigned into 4 equal groups: the control one, E.coli infected group (1×108CFU/I/P/once), the cefepime treated group (45 mg/kg bw/I/M/day) for 5 days and the E.coli infected group that treated with cefepime 24h after bacterial inoculation as previously described. Hematological and immunological parameters, liver function biomarkers and hepatic oxidative stress and antioxidant markers were determined. Results: Our result revealed that E.coli infection induced a significant elevation in the erythrocytes count, hemoglobin concentration, PCV% and total leukocytic count (TLC) (P < 0.05). In the same respect, liver function biomarkers, serum glucose, total cholesterol, and triglyceride levels as well hepatic malondialdehyde (MDA), nitric oxide (NO), TNF-α, IL-10, and lysozyme activity were significantly increased compared to the control rats (P < 0.05). In contrast, hepatic reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) were decreased significantly (P < 0.05). Cefepime treatment in E.coli + CFPM group reduced the elevated eythrogram, TLC and liver function biomarkers. Cefepime also ameliorated the oxidative damage and inflammatory response induced by E.coli infection. Conclusion and clinical relevance: Cefepime is safe when administered in a fixed-dose and possess antioxidant that contributes to improve efficacy against adverse effect induced by E.coli ATCC 25922 infection.

Purpose This paper aims to design to evaluate the protective effect of vitamin E to ameliorate the disturbances in testosterone pathway and sperm quality of male rats induced by the glycosides vicine (V) and convicine (C) of Vicia faba. Design/methodology/approach Forty male albino rats were divided into five equal groups; control, paraffin oil, V (400 mg/kg) C (150 mg/kg)-treated group, vitamin E (100 mg/kg) + VC-treated group, and vitamin E (200 mg/kg) + VC-treated groups which injected intraperioneally (IP) with 0.5-ml saline, 0.5-ml paraffin oil,V (400 mg/kg) and C (150 mg/kg) of Vicia faba, vitamin E (100 mg/kg) + VC-treated groups, and Vitamin E(200 mg/kg) + VC-treated groups, respectively. Blood and testicular tissue were obtained after one month of the study. The male genital organs were calculated. Testosterone (Ts), luteinizing hormone (LH), follicle stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEA-SO4), sex hormone binding globulin (SHBG),?-glutamyl transpeptidase (?-GT), glucose-6-phosphate dehydrogenase (G6PD), 3ß-hydroxysteroid dehydrogenase (3ßHSD), lactate dehydrogenase (LDH), spermatozoa concentration, percent of mortality and abnormal sperms were evaluated. Findings The VC-treated group showed significant decrease (p < 0.01) in Ts, DHEA-SO4, G6PD, spermatozoa number and mortality percent, as well as, the male genital organs (testes, epidydemis, seminal vesicle, prostate and vasa deferentia) while significant increase (p < 0.01) was found in LH, FSH, SHBG, LDH, ?-GT, sperms monoclonal Ki-67, and abnormal spermatocytes levels compared with control group. Vitamin E co-injection with VC-treated group returned all these parameters to the normal values. The higher dose of vitamin E (200 mg/kg) was more effect than the lower dose (100 mg/kg). Originality/value Vicia faba contains V and C glycosides. The V and C glycosides in Vicia faba are hydrolyzed by intestinal microflora to aglycones divicine and isouramil, respectively. Divicine and isouramil are highly reactive compounds generating free radicals where divicine and isouramil are the main factors of favism. The V and C glycosides induced disturbances in testosterone pathway and sperm quality of male rats and vitamin E ameliorates these disturbances.

Background and Objectives: Non-Alcoholic Fatty Liver Disease (NAFLD) is an emerging cause of hepatopathy that is showing an increasing trend and where the recommendations of lifestyle modification are often not sufficient. The aim of this study is to evaluate the efficacy and tolerability profile of the association of silymarin, vitamin C, vitamin E, coenzyme Q10 and selenomethionine (Medronys epato®) by analyzing liver enzymes, along with the lipidic profile, as markers of liver function, and ultrasound results in NAFLD patients. Materials and Methods: This study enrolled 81 patients with mild to severe NAFLD, divided into two groups: Group A (N = 41) received two capsules a day of silymarin, vitamin C, vitamin E, coenzyme Q10 and selenomethionine (Medronys epato®), and Group B (N = 40) received only recommendations for lifestyle modification including hypocaloric diet, physical exercise and encouragement for weight loss. Patients have been evaluated at three timepoints: baseline (T0), after 45 days of treatment (T1) and after 90 days of treatment (T2), by collecting blood parameters of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) and the lipid blood profile. Ultrasonographic results have been analyzed at T0 and T2, along with the tolerability profile and side effects, registered at time T2. Results: The administration of the association of silymarin, vitamin C, vitamin E, coenzyme Q10 and selenomethionine (Medronys epato®) was effective since it showed a significant reduction of the evaluated parameters of ALT, AST, ALP and GGT, a significant improvement of lipid parameters, evaluated as markers of liver function, and improvements of ultrasonographic results. The use of this formulation at the dosage of two capsules a day has been well tolerated and no adverse events have been reported during study period of three months. Conclusions: The administration of the association of silymarin, vitamin C, vitamin E, coenzyme Q10 and selenomethionine (Medronys epato®) was effective and well tolerated in the improvement of hepatic function of NAFLD patients.

AbstractHIV/AIDS related mortality has been dramatically reduced by the advent of antiretroviral therapy (ART). However, ART presents with associated adverse effects. One of such adverse effects is hepatotoxicity observed with nevirapine (NVP) containing ART. Since previous studies showed that NVP hepatotoxicity may be due to oxidative stress via generation of oxidative radicals, this study sought to evaluate the protective effects of antioxidants in alleviating NVP induced hepatotoxicity. Rats were divided into 6 groups with 8 animals per group and received doses of the antioxidants jobelyn (10.7 mg/kg/day), vitamin C (8 mg/kg/day), vitamin E (5 mg/kg/day) and/or NVP (6 mg/kg/day) for 60 days. The animals were sacrificed on day 61 by cervical dislocation, blood samples were collected for biochemical and hematological examination. The liver of the sacrificed animals was weighed and subjected to histopathological examination. There was a statistically significant (p<0.05) elevation in MDA level observed in the NVP group as compared with control. The results further showed non-significant decreases in the levels of MDA in the NVP plus antioxidant groups, except vitamin C, when compared with the NVP alone group. Vitamin E and Vitamin E plus C treated groups showed significantly (p<0.05) higher levels of SOD, CAT and GSH. The results also showed statistically significantly (p<0.05) lower levels of ALT and AST in the antioxidant treated groups There was an observed significantly (p<0.05) higher level of TP and urea in the antioxidant treated rats. A significantly (p<0.05) higher white blood cell count was observed in the antioxidant groups. Histopathological assessment of the liver extracted from the rats showed no visible pathology across the groups. Observations from this study suggest a potentially positive modulatory effect of antioxidants and may be indicative for the inclusion of antioxidants in nevirapine containing ART.

We have examined the effect of subchronic methidathion (MD) administration on heart damage, and have evaluated possible ameliorating effects of a combination of vitamins E and C against MD toxicity. The experimental groups were: control group, rats treated with 5 mg/kg MD and rats treated with 5 mg/kg body weight MD plus vitamin E and vitamin C (MD+Vit). The groups were given MD by gavage 5 days a week for four weeks at a dose level of 5 mg/kg/day (MD and MD+Vit) by using corn oil as the vehicle. Vitamin E and vitamin C were injected at doses of 50 mg/kg i.m. and 20 mg/kg i.p., respectively, after the treatment with MD in the MD+Vit group. The levels of malondialdehyde (MDA) were determined in the heart tissue, and the levels of cardiac troponin I (TnI) in serum. An autoanalyser was used to determine the serum activities of cholinesterase (ChE). Histopathological examination was carried out in the heart tissue. MDA significantly increased in the MD group as compared to controls (P <0.01). When MD was given concurrently with vitamins E and C, the increase in MDA was significantly less (P <0.01). ChE activity significantly decreased in the MD group as compared to controls (P <-0.01). When MD was given concurrently with vitamins E and C, the decrease in ChE activity was significantly higher (P <-0.05). The serum TnI levels significantly increased in the MD group as compared to controls (P <-0.01). When MD was given concurrently with vitamins E and C, the increase in the serum TnI was significantly less (P <-0.01). MD caused the diffuse loss of striation and myocytolysis of the cardiomyocytes, whereas the combination of vitamins E and C caused a significant decrease in these effects of MD. In conclusion, subchronic MD administration caused heart damage and, in addition, treatment with a combination of vitamins E and C after the administration of MD reduced heart damage caused by MD.

Free radical-mediated cell damage can be prevented by well-known antioxidant vitamins such as Vitamins E and C, and it has been reported that Paracetamol can cause hepatotoxicity at high doses. This study evaluated the efficacy of the combination of Vitamin C and Vitamin E in the prevention of renal and hepatic cell damage caused by paracetamol toxicity. Twenty-eight male albino rats were grouped into seven of four rats per group. Vitamin C at prophylactic dosage; (200mg, 150mg, 100mg, 50mg, 25mg) and Vitamin E at prophylactic dosage; (500iu, 400iu, 300iu, 200iu, 100iu) were administered orally to the rats in groups 1 through 5, respectively with concomitant administration 1000mg/kg bw of paracetamol twice daily for seven days. Group 6 was administered 1000mg/kg of paracetamol only (untreated), and Group 7 served as the normal control. The results revealed a significantly (P < 0.05) increase in serum ALT, AST, ALP, Urea and Creatinine of the group administered 1000mg/kg of paracetamol only. The prophylactic doses of ascorbic acid and α-tocopherol significantly (P < 0.05) decrease serum ALT, AST, ALP, Urea and Creatinine level compared to the untreated rats. This study validates that co-administration of ascorbic acid and α-tocopherol at the proposed prophylactic dosages could be used in the prevention of renal and hepatic cell damage caused by paracetamol toxicity.

Background: Anxiety disorders are the most common of all mental health problems. They are more prevalent among women than among men, and they affect children as well as adults. The aim of the current study is to evaluate this problem via an experimental animal model and try to explore its possible mechanisms by studying the effect of Vitamin C compared to Buspirone on anxiety in rats induced by Monosodium Glutamate (MSG).Materials and Methods: 56 healthy adult male albino rats (Sprague-Dawley) weighing 200-250 gm were used and divided into 7 groups (8 rats each). The first and the second groups were provided with normal saline and MSG at a dose of (2 mg/g p.o.) respectively. The other five groups were given MSG and treated daily in the following way: The third and fourth groups were treated with Vitamin C (100, 200 mg/kg p.o) respectively. The fifth group was treated with only Buspirone (10 mg/kg p.o.), while the last sixth and seventh groups were given a combination of Buspirone and Vitamin C with (100, 200 mg/kg) respectively. After 3 weeks, the open field and successive alleys tests were used to assess behavioral changes. The percentage change of systolic blood pressure (SBP) was measured. Additionally, glutathione reductase (GR), malondialdehyde (MDA), and corticosterone levels were determined biochemically.Results: The results after 3 weeks revealed that MSG group showed significant anxiogenic effects in both behavioral tests, with an increased percentage change of SBP in addition to increased malondialdehyde and corticosterone level measured statistically. While the results of the treated groups revealed that the Vitamin C (100mg/kg) treated group demonstrated significant improvement in anxiety levels in the open field test, there were no significant changes in the biochemical assessment. However, vitamin C (200mg/kg) treated group revealed a significant anxiolytic effect in behavioral tests, improved glutathione and malondialdehyde with low corticosterone level. Administration of buspirone revealed significant anxiolytic effects, which is lower than that of vitamin C (200mg/kg). But it caused significant increase in the oxidative stress and corticosterone levels. A combination of buspirone with Vitamin C (200mg/kg) only demonstrated significant anxiolytic effect in both tests and a significant decrease of corticosterone.Conclusion: MSG has neurotoxic effect leading to anxiogenic behaviors in rats which are opposed by Vitamin C. Furthermore, as an antioxidant, vitamin C protects against the oxidative stress induced by MSG. Moreover, it lowers the high corticosterone level associated with MSG or buspirone administration.Key Words: MSG, vitamin C, buspirone, glutathione reductase, malondialdehyde, open field, successive alleys
