OPEN ACCESS International Journal of Pharmacology ISSN 1811-7775 DOI: 10.3923/ijp.2017.529.540 Research Article Hepatoprotective Effect of Diosmin on Iron-induced Liver Damage 1 Mustafa Ahmed Abdel-Reheim, 1 Basim Anwar Shehata Messiha and 2 Ali Ahmed Abo-Saif 1 Department of Pharmacology and Toxicology, Faculty of Pharmacy, Beni-Suef University, Beni-Suef, Egypt 2 Department of Pharmacology and Toxicology, Faculty of Pharmacy, Nahda University, Beni-Suef, Egypt Abstract Background and Objective: Liver injury is an ascending healthcare challenge. The aim of the present investigation was to elucidate the possible protective effect of diosmin against ferrous sulfate-induced liver injury in adult male albino rats. Methodology: Animals were divided into 6 groups; group 1: Normal control (tween 80, p.o., 10 days), group 2: N-acetylcysteine control (300 mg kg G 1 day G 1 , p.o., 10 days), group 3: Diosmin control (20 mg kg G 1 day G 1 , p.o., 10 days), group 4: Ferrous sulphate (two doses of ferrous sulfate, 30 mg kg G 1 day G 1 , i.p., at 9 th and 10 th day), group 5: N-acetylcysteine (300 mg kg G 1 day G 1 , p.o., 10 days) plus ferrous sulphate (two doses of ferrous sulfate, 30 mg kg G 1 day G 1 , i.p., at 9 th and 10 th day) and group 6: Diosmin (20 mg kg G 1 day G 1 , p.o., 10 days) plus ferrous sulphate (two doses of ferrous sulfate, 30 mg kg G 1 day G 1 , i.p., at 9 th and 10 th day). On the 11 th day, blood and tissue samples were collected Statistical analysis was carried out using one way analysis of variance ANOVA test followed by Tukey-Kramer multiple comparisons test, with value of p<0.05 considered significant. Results: Iron-induced liver injury was evidenced by significant increase in hepatocyte membrane damage markers (serum ALT, AST, ALP, GGT, LDH and bilirubin), oxidative and inflammatory markers (hepatic MDA content and NO x production) and dyslipidemic markers (serum TC and TG) (p<0.05). In addition, significant decreases in hepatic GSH content and serum albumin were noted (p<0.05). Treatment with diosmin significantly improved hepatocyte membrane damage markers (showing reductions ranging from 24-48%), oxidative and inflammatory markers (showing 34 and 32% reductions regarding MDA and NO x , respectively), dyslipidemic markers (showing 35 and 39% reductions regarding serum TC and TG, respectively) (p<0.05). Histopathological investigation of liver sections, in addition to immunohistochemical investigations of iNOS and eNOS in liver sections, strongly supported biochemical findings. Conclusion: Diosmin may have good hepatoprotective effect, mostly through antioxidant and anti-inflammatory potentials. Modulation of NOS expression may have a key role in such protection.

Int. J. Pharmacol., 13 (6): 529-540, 2017 INTRODUCTION Iron is a very important polyvalent cation in the body, present in hemoglobin, cytochrome oxidases and other complexes 1 . Physiologically, iron is always present in the body in a bound form, namely with transferrin, ferritin and hemosiderin 2 . If iron load exceeds iron binding capacity, free iron will therefore cause massive oxidative stress, inflammatory reactions and ultimately tissue necrosis. Free iron enhances Reactive Oxygen Species (ROS) formation and lipid peroxidation 3,4 . Iron sulfate has been chosen as a toxic substance for the liver because it is found in many pharmaceutical preparations in the home. There have been many accidents with overdose, either intentionally or accidentally, as happens with children 5 Ferrous sulphate significantly elevated serum activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (p<0.05) which indicated hepatocyte membrane damage and release of intracellular hepatic enzymes into circulation. In agreement with Bhattacharya et al 6,7 who stated that 30 mg kg G 1 ferrous sulphate significantly produced hepatotoxicity in rats evidenced by significant elevations in serum ALT and AST (p<0.05). Similarly, Pari et al 8 stated that 30 mg kg G 1 ferrous sulphate significantly increased serum hepatic markers (p<0.05). In particular, serum ALT and AST levels are among the most sensitive indicators of hepatocye membrane damage 9,10 Diosmin (Diosmetin-7-O-rutinoside), a naturally occurring flavones glycoside readily obtained by dehydrogenation of hesperidin, found abundantly in the pericarp of various citrus 11 . Diosmin has various biological activities including antioxidant activity 12 , anti-inflammatory effect 13 , anti-diabetic effect 14 and anti-proliferative and anti-cancer activities 12,15 More-over, diosmin has been found to increase the venous tone and reduce the capillary hyperpermeability, thereby, leading to inhibition of the release of inflammatory mediators 16 . Besides, diosmin has been found to have hepatoprotective effect against many toxic agents 17 The currently available hepatoprotective drugs such as ursodeoxycholic acid and the other modern hepatoprotective drugs would produce lots of undesirable side effects 18 . Hence, it is of great value to find safe hepatoprotective constituent of herbal medicine, which could alleviate and prevent the progression of hepatic diseases 17 . Although anti-oxidant properties of diosmin have been reported in previous studies 19,20 , the effect of diosmin on ferrous sulphate-induced hepatptoxicity has not been investigated. Therefore, the aim of this study was to elucidate the possible protective effect of diosmin against iron-induced hepatotoxicity as compared to N-acetyl cysteine (NAC) as standard treatment in adult male albino rats. MATERIALS AND METHODS Materials Animals: Adult male albino rats, 200-250 g were obtained from the National Research Center, Cairo, Egypt. Animals were housed in plastic cages (28×43×18 cm) and were maintained under standard conditions of temperature (25ºC±1) and humidity. Animals were maintained in a clean rodent room and well ventilated with a 12 h light/dark cycle throughout the experimental period in the last winter in Faculty of Pharmacy, Beni-Suef University and were fed standard pellet chow (El-Nasr chemical Co., Cairo, Egypt) with free access to water ad libitum .

Int. J. Pharmacol., 13 (6): 529-540, 2017 Group 1: Normal control (tween 80) Group 2: N-acetylcysteine (300 mg kg G 1 day G 1 ) alone Group 3: Diosmin (20 mg kg G 1 day G 1 ) alone Group 4: Hepatotoxicity control group (two doses of ferrous sulphate, 30 mg kg G 1 day G 1 , i.p. at 9 th and 10 th day) Group 5: N-acetylcysteine plus ferrous sulphate Group 6: Diosmin plus ferrous sulfate Group 2 and 3 were given the test agents alone to study the effect of these agents on normal rats Treatments were given to rats as oral daily dose for 10 consecutive days. Hepatic injury was induced by i.p. injection of two doses of ferrous sulphate (30 mg kg G 1 ) at 9 th and 10 th day. Methods Induction of liver injury (Ferrous sulphate model): The model was modified from the method described by Bhattacharya et al 6 . The modification was in the number of ferrous sulphate doses where two doses of ferrous sulphate were given instead of one dose in the original model. Treatment agents were given to rats as oral daily dose for 10 consecutive days. Hepatic injury was induced by i.p. injection of two doses of ferrous sulphate (30 mg kg G 1 ) at 9 th and 10 th day. Animals were anaesthetized by thiopental sodium (75 mg kg G 1 , i.p.) and blood samples were collected from retro-orbital plexus using heparinized micro-capillary tubes. After that, rats were sacrificed by cervical dislocation to separate liver samples 23 . Manipulation of samples Blood samples: After collecting blood samples in centrifuge tubes, the tubes were allowed to coagulate at room temperature, then placed in water bath at 37 E C for 10 min Centrifugation at 1000×g for 20 min was performed. The clear serum was separated and used for analysis of biochemical parameters, including ALT, AST, ALP, LDH, GGT, bilirubin, TC and TG. Liver samples: After animals were sacrificed, the abdominal cavities were opened and livers were carefully separated, washed with ice-cold saline and the median and left hepatic lobes were used for the preparation of liver homogenate as well as immunological and histopathological examination. Preparation of liver homogenate: To prepare 20% liver homogenate, 1 g of the median lobe was homogenized with 5 volumes of isotonic ice-cooled normal saline using a homogenizer (IKA homogenizer, Model T 25 digital ULTRA-TURRAX, Germany) for the estimation of hepatic MDA and GSH contents as oxidative biomarkers and nitrate/nitrite (NO x ) production as inflammatory biomarker. Preparation of slides for immunological and histopathological examination: A portion of the liver was kept in well-sealed containers in formalin solution (10%) in normal saline prior to wax embedding, sectioning and staining with haematoxylin and eosin (H and E) for immunological and histological evaluation of liver damage using light microscope attached to a digital camera. Measurement of biomarkers: Serum ALT and AST were determined according to the method of Reitman and Frankel 24 using commercial kits. Serum ALP was determined according to the method of Belfield and Goldberg 25 . Serum GGT was determined according to the method of Szasz 26 using commercial kits. Serum LDH activity was determined according to the method of Vassault 27 using commercial kits The GSH was measured in liver homogenate according to the method described by Sedlak and Lindsay 28 . Lipid peroxidation was determined in liver homogenate as thiobarbituric acid reactive substances (TBARS) that were measured as MDA according to the method of Uchiyama and Mihara 29 . The NO x production in liver tissue was assayed according to the method described by Miranda et al 30 . Serum TG level was assayed according to the method described by Bucolo and David 31 using commercial kits. Serum TC level was assayed according to the method described by Boussekine et al 32 using commercial kits. Serum albumin was determined according to the method of Tietz 33 using commercial kits Serum total, direct and indirect bilirubin were determined according to the method of Tietz 34 using commercial kits. Histopathological assessment of liver injury: Autopsy samples were taken from the liver of rats in different groups and fixed in 10% formalin solution in normal saline for 24 h Washing was done in tap water then serial dilutions of alcohol (methyl, ethyl and absolute ethyl alcohols) were used for dehydration. Specimens were cleared in xylene and embedded in paraffin at 56 E in hot air oven for 24 h. Paraffin bees wax tissue blocks were prepared for sectioning at 4 microns thickness by sledge microtome. The obtained tissue sections were collected on glass slides, deparaffinized, stained by hematoxylin and eosin (H and E) stain for routine examination then examination was done through the light electric microscope. 531

Int. J. Pharmacol., 13 (6): 529-540, 2017 Immunohistochemistry: Immunohistochemistry was performed according to the method of Merz et al 35 . The labelled streptavidin biotin (LSAB) staining method was used in which horseradish peroxidase (HRP), streptividin and two-tiered antibodies were employed to reveal the presence of antigens in a variety of tissues and cell preparations. After the primary antibody has been bound to a target antigen, a secondary antibody that binds specifically to that primary antibody was used. The HRP-labelled streptividin is then bound to the biotinylated secondary antibody and the entire complex is revealed by adding a substrate/chromogen mixture which create an intense color deposit through the activity of the bound enzyme Statistical analysis: Data were expressed as the Mean±Standard Error of the Mean (SEM) and comparison between the different treatments was carried out using one-way analysis of variance (ANOVA) test followed by Tukey-Kramer multiple comparisons test, with value of p<0.05 considered significant.

Int. J. Pharmacol., 13 (6): 529-540, 2017 DISCUSSION In this study, diosmin effect was studied in hepatotoxic rats. Hepatotoxicity was induced by ferrous sulphate which increased hepatic markers. Ferrous sulphate significantly elevated serum activities of ALT, AST, ALP, GGT, LDH and bilirubin (p<0.05) which indicated hepatocyte membrane damage and release of intracellular hepatic enzymes into circulation. Increase in serum level of ALP is due to increased synthesis, in presence of increasing biliary pressure 36 . The LDH is also an intracellular enzyme, whose release indicates cell damage 37 . Serum GGT has been used as indicator of liver dysfunction and in the presence of iron, the products of the GGT reaction may themselves increased the production of free radical 38 . Findings of the present study revealed that ferrous sulphate caused significant increase in liver MDA and NO x production as compared to normal control group (p<0.05) and significant reduction in liver GSH content (p<0.05). The results of the present study are in accordance with those obtained by other investigators 8,39 . The target of iron toxicity is the mitochondrion, where iron overload causes oxidative mitochondrial membrane damage and damage of enzymes of the tri-carboxylic acid cycle 40 . Iron has redox properties and consequently it catalyzes a number of functions in the cells 41 However, these redox properties render iron able to generate ROS and destroy liver cells 42 . The alterations in structure and function of cells caused by overload of iron seem to be related to free radical-mediated cell components damage. The chemical structure of iron and its ability to drive one-electron reactions makes it a major player in the production of free radicals in the biological systems 43 . Iron overload was found to induce nitric oxide expression leading to increased nitric oxide production which form peroxynitrite (in combination with superoxide anions) which is dangerous mediator of lipid peroxidation 44 . It is clear from the immunohistochemical study that iron administration caused significant increase in iNOS expression (p<0.05), potentiating oxido-nitrosative stress and inflammatory outcome. Concerning the results of the present study, too, ferrous sulphate showed significant elevation of serum levels of TG and TC (p<0.05). Similar results were obtained by Pari et al 8 who reported that serum cholesterol and triglycerides levels were significantly higher in rats after administration of 30 mg kg G 1 ferrous sulphate when compared to normal group (p<0.05). Ferrous sulphate causes disturbances of mitochondrial function, which leads to inhibition of $ -oxidation and accumulation of serum free fatty acids and triglycerides. Serum cholesterol also increased due to changes in the expression of the gene of the liver enzyme HMG-COA reductase 45 . Findings of the present study revealed that iron overload significantly reduced serum albumin level as compared to normal control group (p<0.05). The results are in accordance with those obtained by Kaur et al 46 who reported that serum albumin level was significantly lower in mice after i.p administration of 9 mg kg G 1 ferric nitrilotriacetate when compared to normal group (p<0.05). Albumin is the most important protein synthesized in the liver and its concentration is a good indicator of liver functional integrity 47 . Findings of the present study revealed that iron overload significantly increased serum bilirubin level as compared to normal control group (p<0.05). The results of the present study are in accordance with those obtained by Pari et al 8 who reported that serum bilirubin level was significantly higher in rats after administration of 30 mg kg G 1 ferrous sulphate as compared to normal group (p<0.05). Bilirubin is the excretory end product of heme degradation. It is conjugated in the liver with glucuronic acid and then excreted into the bile. Elevated plasma concentration of free (indirect) bilirubin is a marker for serious liver injury 47 The current data showed that diosmin significantly suppressed ferrous sulphate-induced increase in serum activities of ALT, AST, ALP, GGT and LDH (p<0.05). The results are in accordance with those obtained by Tahir et al 22 who stated that diosmin protect liver cells against ethanol induced hepatotoxicity in rats. Diosmin restored the changes in serum activities of ALT, AST, ALP, GGT and LDH due to its antioxidant effect, thereby protecting membrane permeability 22 . Findings of the present study revealed that diosmin caused significant decrease in liver MDA and NO x production as compared to ferrous sulphate control group (p<0.05), coupled with significant increase in liver GSH content (p<0.05). The results are in accordance with those obtained by other investigators, where Abdel-Salam et al 17 stated that diosmin counteracted lipopolysaccharide-induced oxidative stress due to its antioxidant effect. Concerning the results, diosmin showed significant decrease of serum levels of TG and TC as compared to ferrous sulphate group (p<0.05). The results are in accordance with those obtained by Queenthy and John et al 48 who studied the effect of diosmin on serum triglycerides in isoproterenol induced myocardial infarcted rats. The effect of diosmin is 537

Int. J. Pharmacol., 13 (6): 529-540, 2017 related to inhibition of both hepatic HMG CoA reductase and acyl CoA cholesterol acyl-transferase (ACAT) activities 48 . Diosmin corrected the serum level of albumin due to its ability to protect the hepatocytes against toxic injuries and restore the normal function of the liver 22 . Findings of the present study revealed that diosmin significantly decreased serum bilirubin level as compared to ferrous sulphate control group (p<0.05). the results are in accordance with those obtained by Tahir et al 22 who studied the effect of diosmin in ethanol-induced hepatotoxicity in rats. The elevated serum level of bilirubin is an indicator of hepatocyte injury 49 . Diosmin protect liver cells against toxicity due to its antioxidant effect, thereby protecting membrane permeability and decreasing serum bilirubin 22 . The immunohistochemical study results showed that suppression of iNOS expression may be, at least partly, a logic mechanism of antioxidant and anti-inflammatory effects of diosmin. NOx overproduction causes oxido-nitrosative stress since peroxynitrite, the product of interaction between nitrite and hydrogen peroxide, is a highly damaging agent 50 . The eNOS releases physiological beneficial levels of nitric oxide 51 , while iNOS is up-regulated in pathological conditions, causing deleterious effects 52 . Interestingly, diosmin in the current study ameliorated harmful iNOS expression without ameliorating eNOS expression. CONCLUSION It is concluded that ferrous sulphate produced severe hepatotoxicity in rats, where oxidative stress play an important role as evidenced by increased liver contents of MDA, NO and depletion of GSH. Diosmin is actually a good hepatoprotective agent preserving membrane integrity, ameliorating oxido-nitrosative stress and correcting dyslipidemia. Suppression of iNOS expression may be a logic mechanism involved in such protection. These results are promising for further clinical trials. SIGNIFICANCE STATEMENTS This study discovered that diosmin can be a promising agent for clinical use as hepatoprotection against ferrous sulphate-induced hepatotoxicity. Their effects were similar to that of N-acetyl cysteine. This study also signifies that the most likely proposed mechanism for the hepatic protection conferred by this drug is related to its antioxidant properties and its ability to decrease inducible reperfusion nitric oxide and increase ischemic nitric oxide ACKNOWLEDGEMENT The author would like to thank the Dr. Samraa Hussein Abdel-Kawy, Lecturer of Histology, faculty of Medicine, Beni-Suef University, for her help and support in performing the histopathological study.
