Liver disease remains a significant global health problem. Increased caffeine consumption has been associated with a lower prevalence of chronic liver disease. This study aimed to investigate the modifying effects of caffeine on liver injury induced by thioacetamide (TAA) administration in male rats and the possible underlying mechanisms. Forty adult male rats were equally classified into four groups: control group, received only tap water; caffeine-treated group, received caffeine (37.5 mg/kg per day); TAA-treated group, received intraperitoneal (i.p.) TAA (200 mg/kg b.w.) twice a week; and caffeine + TAA-treated group, received combined TAA and caffeine in the same previous doses. After eight weeks of treatment, blood samples were collected for biochemical analysis and liver specimens were prepared for histological and immunohistochemical studies and for assessment of oxidative stress. TAA induced liver toxicity with elevated liver enzymes and histological alterations, fatty changes, apoptosis, and fibrosis evidenced by increased immunohistochemical reaction to matrix metalloproteinase-9 (MMP-9) and collagen type IV in hepatocytes. Also, the levels of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) in serum were significantly elevated. Co-treatment with caffeine and TAA restored normal liver structure and function. Caffeine provided an anti-fibrogenic, anti-inflammatory, and antioxidant effect that was associated with recovery of hepatic histological and functional alterations from TAA-induced hepatotoxicity.

The evaluation of the effect of ginger on the modulation of toxic effects induced by lead is the objective of our study. Forty male rats were randomly divided into four groups and treated daily for 3 consecutive months. Group I (0-0) was kept as control; group II (0-G) received an experimental diet with 2% of ginger; group III (Pb-0) received 2% lead acetate dissolved in drinking water with a normal diet; and group IV (Pb-G) received 2% lead acetate in drinking water and an experimental diet containing 2% ginger. Lead acetate exposure caused a significant increase of organosomatic indexes, hepatic, lipid, and urine profiles. In addition, lead acetate has a pro-oxidative effect expressed by a significant decrease in tissue GSH levels and the enzymatic activity of GPx and CAT. This pro-oxidative action was also marked by an increase in MDA level and GST activity in lead-treated group. Feeding ginger-supplemented diet to lead acetate-treated rats restored all the parameters studied as compared to control. These results suggest that ginger treatment exerts a protective effect on metabolic disorders by decreasing the oxidative stress.

Myocardial infarction (MI) is a common cause of death due to interrupted blood supply to the heart. Roselle calyx (Hibiscus sabdariffa Linn.) is rich in polyphenols and has a potential in alleviating the risk of cardiovascular disease through its antioxidant activity. This study was aimed to investigate the effects of Hibiscus sabdariffa Linn. or roselle polyphenol-rich extract (HPE) supplementation in oxidative stress and cardiac injury biomarkers as well as cardiac histological changes following isoprenaline (ISO)-induced myocardial infarction (MI). Twenty-one male rats were randomly divided into three groups: control, MI, and HPE+MI. Normal saline or HPE (20 mg/kg BW) was given to MI and HPE+MI groups, respectively, for 14 consecutive days via force feeding. On the 15th and 16th day, 85 mg/kg body weight of ISO was administered subcutaneously to induce MI. Control group was only given normal saline throughout this 16-day duration of study. The results showed that HPE reduced the oxidative stress markers malondialdehyde (MDA) and nitrite oxide (NO) in HPE+MI group when compared with MI group (p<0.05) while increased reduced glutathione (GSH) level reflexes the improvement in antioxidant status. Cardiac injury biomarkers analysis showed no significant difference in HPE+MI group when compared to MI group. Histological study showed that HPE managed to reduce cardiac muscle fibre damage and infiltration of inflammatory cells in ISO-induced MI rats. In conclusion, HPE has the potential in protecting the heart against ISO-induced MI by reducing the oxidative stress and increasing antioxidant status.

The aim of this experimental study was to investigate the possible role of nitric oxide (NO) and the activities of adenosine deaminase (ADA) and xanthine oxidase (XO) in the pathogenesis of isoniazid (INH)-induced oxidative damage in red blood cells (RBCs), and also to show the effect of caffeic acid phenethyl ester (CAPE) and erdosteine, antioxidants, in decreasing this toxicity. A total of 25 adult male rats were divided into four experimental groups as follows: control group ( n = 7), INH-treated group ( n = 6), INH + CAPE–treated group ( n = 6), and INH + erdosteine–treated group ( n = 6). INH, INH-CAPE, and INH-erdosteine–treated groups were treated orally with INH 50 mg/kg daily and with the tap water for 15 days. Control group was given only tap water. CAPE was intraperitoneally injected for 15 days at a dose of 10 μmol/kg. Erdosteine was treated orally for 15 days at a dose of 10 mg/kg/day. The injection of INH led to a significant increase in the activities of ADA, XO, and NO levels in RBCs of rats. Co-treatment with CAPE caused a significant decrease in the activities of ADA and XO and the levels of NO in RBCs. In addition, co-treatment with erdosteine caused a significant decrease in the activities of ADA and XO and the levels of NO in RBCs. The results of this study showed that ADA, XO, and NO may play an important role in the pathogenesis of INH-induced oxidative stress in RBCs. CAPE and erdosteine may have protective potential in this process and they may become a promising drug in the prevention of this undesired side effect of INH.

The purpose of the experiment is an investigate the association of walnut oil with lipid profiles, glucose as well as total proteins and assessment its side effect on some sensitive organs such as the liver and spleen tissues. The experiment divided into two main groups are treated group with walnut oil and the control group, where the former divided into two subgroups 0.25 and 0.5 ml of oil per each. We found a statistically non-significant difference between treated and control groups (for total protein, lipid profile, and glucose). There was no change in total protein, but cholesterol decreased by 0.25 ml but a little increased by 0.5 ml. HDL was increased for the treated group. While on 0.25 ml LDL decreased in treated animals, on another hand no change for 0.5 ml. Also, no change for VLDL between treated and control. The only triglyceride was increased but non-significant for the treated group compared with the control. Both doses decreased in treated animals for glucose. We also found an increase in whole-body weight and on sensitive organs such as the liver and spleen. Even no change in a histological study for the mentioned organs. The conclusion: By walnut oil, all parameters have changed despite the treated group was normal without any induced diseases. So, recommended the researchers induce the disorders in the liver and assessment the extracted oil on the lipid profile.

This study evaluated the possible ameliorative effect of hydromethanol extract of Thymus vulgaris on hepatorenal toxicity induced by cadmium in male rats. The experimental animals were divided into four groups and treated as follows: A (control - 0.5ml of 2% tween 80 in distilled water per os) for 3 weeks and a single subcutaneous dose of phosphate buffered saline, B (single subcutaneous dose of cadmium in phosphate buffered saline at 3 mg/kg); C (500 mg/kg extract per os daily for 3 weeks) and D (single subcutaneous dose of cadmium in phosphate buffered saline at 3 mg/kg + 500 mg/kg extract per os daily for 3 weeks). Cadmium administration resulted in suppression of erythrocyte count, hemoglobin concentration, packed cell volume, an elevated total leucocyte count with associated neutrophilia which improved with extract administration. Levels of serum alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase, creatinine and total bilirubin concentration increased with decrease in total serum protein and albumin in cadmium treated group B compared to control group A, group C (extract only) and cadmium plus extract treated group D. Cadmium led to a reduction in catalase and superoxide dismutase activities with increase in the level of malondialdehyde. However, co-administration of extract with cadmium in group D reduced lipid peroxidation and oxidative stress induced by cadmium. Histopathological examination of cadmium treated groups showed moderate vacuolar degeneration in the liver and degeneration of the kidney tubules which were ameliorated following co-administration with extract. This study shows that Thymus vulgaris extract has a potential protective effect against cadmium induced hepato-renal injury through the suppression of oxidative stress.

Abstract Background Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease in the Western world, and it’s likely to parallel the increasing prevalence of type 2 diabetes, obesity, and other components of metabolic syndrome. However, optimal treatment for NAFLD has not been established yet. Therefore, this study investigated the hepatoprotective effect of silymarin on fructose-induced nonalcoholic fatty liver disease in rats. Methods Thirty male Wistar rats were randomly divided into five groups; normal control group that consumed tap water, silymarin control group that consumed tap water and silymarin (400 mg/kg/day), fructose control group that consumed 20% fructose solution, treatment group that consumed 20% fructose solution and silymarin (200 mg/kg/day), and another treatment group that consumed 20% fructose solution and silymarin (400 mg/kg/day). Hepatic triglyceride, serum lipid profile, lipid peroxidation, antioxidant level, morphological features, and histopathological changes were investigated. The data were analyzed using one-way analysis of variance (ANOVA) followed by Tukey multiple comparison test. Statistical significance was determined at p < 0.05. Results This study showed that the fructose control group had a significantly high value in the stage of steatosis grade, hepatic triglyceride, serum triglyceride, total cholesterol, low-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, and hepatic malondialdehyde concentration as compared to the normal control. However, significantly low values of reduced glutathione and plasma total antioxidant capacity were found. The altered parameters due to fructose drastic effect were ameliorated by silymarin treatment. Conclusions The fructose control group developed dyslipidemia, oxidative stress, and mild steatosis that are the characteristics features of NAFLD. However, silymarin-treated groups showed amelioration in oxidative stress, dyslipidemia, and steatosis.

Introduction: Diclofenac (DIC) is one of the compounds derived from acetic acid which isknown for its anti-inflammatory and analgesic attributes. Silymarin is a flavonoid compoundwhich is derivate from Silybum marianum seeds. This research was done to assess the protectiverole of silymarin against liver toxicity induced by DIC in male rats.Methods: Randomly, 40 male Wistar rats were assigned into five groups as follows: Group 1:control group, Group 2: DIC-only treated (50 mg/kg, i.p), Group 3: silymarin-only treated (200mg/kg, p.o); Groups 4 and 5: DIC (50 mg/kg, i.p) plus silymarin (100 mg/kg and 200 mg/kg, p.o,respectively) treated. Various biochemical, molecular, and histological parameters were evaluatedin serum and tissue.Results: In the DIC-only treated group, the levels of liver glutathione peroxidase (GPx), superoxidedismutase (SOD), intracellular glutathione (GSH) and catalase (CAT) significantly diminished andthe levels of total bilirubin, alkaline phosphatase (ALP), nitrite, alanine aminotransferase (ALT),malondialdehyde (MDA), serum tumor necrosis factor-α (TNF-α), aspartate aminotransferase(AST), and TNF-α gene expression were remarkably elevated relative to control animals. In otherhands, treatment with silymarin caused a noticeable elevation in GPx, SOD, GSH, CAT and aremarkable reduction in levels of total bilirubin, ALP, nitrite content, ALT, MDA, serum TNF-α,AST and TNF-α gene expression relative to DIC-only treated group. Histopathological injurieswere also improved by silymarin administration.Conclusion: The results confirm that silymarin has an ameliorative effect on liver toxicity inducedby DIC and oxidative stress in male rats.
