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.

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.

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.

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.

Abstract Tramadol is a synthetic opioid analgesic used for moderate-to-severe pain structurally related to codeine and morphine, where their analgesic mechanism is a result of opioid and non-opioid mechanisms. This study was designed to evaluate the effects of Moringa oleifera leaves extract (MLE) on tramadol-induced testicular toxicity, sperm changes, testicular damage, and oxidative stress in male rats. Forty male albino rats were divided into four groups and treated for 4 weeks (group 1, as control; group 2, MLE; group 3, tramadol; group 4, MLE + tramadol). The relative body weight, relative testes weight, serum total testosterone, luteinizing hormone, follicle-stimulating hormone, sperm counts, vitality, total sperm motility, catalase, and superoxide dismutase activities were significantly decreased in tramadol-treated group when compared with the control group. In contrast, sperm abnormality, immotile sperm percent, testicular injury, and TBARS concentration in testes were significantly increased in the tramadol-treated group. In addition, histopathological examination for the tramadol-treated group has shown incomplete spermatogenesis, moderate degeneration in some seminiferous tubules with a significant decrease in the number of spermatogenic cells and depletion of Leydig cells. The administration of MLE with tramadol ameliorates the testicular toxicity, injury, sperm count, abnormalities, and oxidative stress induced by tramadol.

Ginseng Extract

This study investigates the modulating effect of ginseng against testicular toxicity, oxidative stress and changes in some biochemical parameters induced by doxorubicin. Twenty male rats were divided into four groups. The 1st group received distilled water orally (control group), The 2nd group received doxorubicin (5 mg/kg b.wt. intrapertenoineal) once a week for eight weeks, The 3rd group received ginseng extract (200 mg/kg b.wt.) daily for eight weeks and the 4th group received doxorubicin with ginseng extract by the same doses as in the 2nd and the 3rd groups respectively. At the end of the 8th week, blood and semen samples were taken for biochemical and semen analysis, respectively. The doxorubicin treated group had significantly higher serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), Creatine kinase (CK) and lactate dehydrogenase (LDH) along with lower levels of total protein, albumin and globulin. In addition, a significant decrease in antioxidant enzymes (SOD, CAT, GSHPx), and glutathione (GSH) associated with higher level of malondialdehyde (MDA) were observed. At the same time, the group that took doxorubicin with ginseng did not differ from control group in terms of these parameters. Male fertility study showed changes in testosterone and semen analysis in both groups treated with doxorubicin, while the group that took doxorubicin with ginseng showed an improvement towards control levels of these parameters. Thus ginseng supplement can reduce the negative effects of doxorubicin- induce.

This study was conducted to investigate the protective role of polyphenolic compounds extracted from olive (Oleaeuropae) to contrast the damaging effects of 1% hydrogen peroxide on liver functions in male rats. Crude polyphenolic compounds were extracted from fruits of black olive by 95% methanolic extraction method. Twenty adult male rats (200-220gm.) were randomly divided into four equals groups and treated daily for 30 days. Rats in the first group received tap water (orally)and considered as control group, animals of second group received 1% H2O2 in drinking water . The rats in the third group received 1% H2O2 in drinking water plus 200mg/kgB.W. of crude polyphenolic compounds while animals in the fourth group received 200mg/kg B.W. of crude polyphenoliccompounds. At the end of the experiment, blood samples were taken to investigate the activity of liver enzymes (Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT), concentration of total serum bilirubin, as well as protein picture of blood serum by using agarose gel electrophoresis. Ultimately, animals of all groups were sacrified to examine the histopathological changes in liver. The results illustrated significant increase (P<0.05) in liver enzymes activity (AST,ALT) and total serum bilirubin in H2O2 treated group as compared with control. Although rats treated polyphenolic compounds of olive plus H2O2 showed significant decrement (P<0.05) in ALT activity and total serum bilirubin, while no significant alteration in (AST) activity was recorded in H2O2 treated group. The result also demonstrated significant decrease (P<0.05) in authority of ALT, total serum bilirubin in animals treated with polyphenolic compounds. Serum proteins showed a significant (P<0.05) decreament of albumin percentage and increment of globulins in H2O2 treated group as well as polyphenolic compounds treated group as compared with control group (G1) . However, no significant different in group treated with polyphenolic compounds as compared with control. Histological sections of liver illustrated clear impact of group treated with H2O2, manifested by necrosis of hepatic cells with infiltration of inflammatory cells while animals treated with polyphenolic compounds plus H2O2 revealed slight infiltration of inflammatory cells with proliferation of kupffer cells in liver. In infereance, the autcomes of this study documented the advantageous effect of crude polyphenolic compounds of olive apposite the noxious effect of H2o2 on liver function of adult males rats.

Abstract. It has been suggested that treatment of intact male rats with oestradiol benzoate (OeB) causes an interference with testosterone (T) production by the testes by a direct inhibitory effect on steroidogenesis. To test this hypothesis, different doses (5, 10 or 25 IU) of hCG were administered concomitantly with 50 μg of OeB to adult intact or hypophysectomized male rats. The testicular and plasma testosterone, and serum hCG levels were determined. The sex accessory weights were recorded. In the intact OeB-treated group of animals, hCG stimulated both the secondary sex organs and plasma testosterone levels above the intact control group. However, in hypophysectomized animals, although plasma testosterone levels increased above that of intact controls, their secondary sex organ weights did not. Moreover, inspite of high circulating hCG levels, the testicular testosterone content and concentration remained suppressed in OeB-treated animals. The reason for such dichotomy of hCG action on OeB-treated animals is not clear at present.

Phytochemical composition and antioxidant activity of flowers decoction at post-flowering stage (F3D) of Opuntia dejecta were determined. The obtained findings demonstrate that F3D has a marked antioxidant activity in all tested assays. Furthermore, the present study was designed to test the protective activity of F3D against induced Diabetes type 2 (DT2) in male rats. Those metabolic syndromes were induced by a high-fructose diet (HFD) (10% fructose solution) for a period of 20 weeks. F3D was administered orally (100 and 300 mg/kg body weight) daily for the last 4 weeks. Metformin (150 mg/kg body weight) was used as a standard drug and administrated orally for the last 4 weeks. The results showed a significant increase in blood glucose, triglycerides and hepatic markers (ALAT, ASAT and ALK-P) in HFD group. A significant increase in hepatic TBARS and a significant decrease in SOD, CAT and GPX were observed in fructose fed rats compared to control group. Administration of F3D showed a protective effect in biochemical and oxidative stress parameters measured in this study. Also, oral administration of F3D restored the histological architecture of rat liver in comparison with rats fed HFD. In conclusion, F3D attenuated hepatic oxidative stress in fructose-fed rats.

The Difference

Hypertension has been linked to a progressive increased in oxidative stress and inflammation. The high prevalence of hypertension poses a great risk to public health as 108 million adults in the United States have the condition. For that reason, a better understanding of the link between a high Na+ intake and the development of hypertension is of crucial importance. We hypothesize that a single ingestion of a high Na+ solution leads to increased oxidative stress and triggers an inflammatory response. Wistar 200-250 g male rats had gastric infusions through the esophagus. Groups were infused with 8 mL liquid Vaseline (Control), 8 mL of NaCl 0.684 M (4% m/v), and 8 mL of NaCl 1.368 M (8% m/v). After infusion, blood was collected at different time points during the first hour. Tissue samples were obtained from the aorta, heart, and kidney. Electron Microscopy (EM) was performed on all tissues, which were also analyzed for molecular markers of oxidative stress: Superoxide Dismutase (SOD) and Malondialdehyde (MDA), and an inflammation marker: Extracellular Signal-Regulated Kinase (ERK). At 2 and a half minutes, serum Na+ concentration was unchanged in the control group compared to an increase observed in animals receiving 4% and 8% Na+ with concentrations of 135±1.4 mEq/L, 141±2.0 mEq/L, and 140±1.2 mEq/L respectively. At the 1-hour time point after infusion, the difference was further increased in the 8% group with serum concentrations of 135±1.8 mEq/L, 140±1.5 mEq/L, and 152±1mEq/L respectively (p<0.05). There was an increase in oxidative stress in the aorta from values of 36.22±4.64 mU/mg SOD and 0.131±0.013 pg/mL MDA in the control group, to 47.11±4.89 mU/mg SOD and 0.291±0.022 pg/mL MDA in the 8% group (p<0.05 in both cases). The same was observed in the heart, where values were: 174.6125.26 mU/mg SOD, 0.026±0.007 pg/mL MDA in controls, and 259.22±21.98 mU/mg SOD, 0.215±0.073 pg/mL MDA in 8% group (p<0.05 both cases). Increased ERK in aortic tissue, values of 0.29±0.03 pg/mL in controls, 2.68±0.18 pg/mL in 4% group and 3.97±0.68pg/mL in 8% group (p<0.05) suggest increased inflammation. We conclude that the elevation in serum Na+ concentration that follows Na+ ingestion leads to increased oxidative stress and inflammation.
