Abstract
Background Organ ischemia-reperfusion (IR) is a common clinical condition associated with various situations such as trauma surgery, organ transplantation, and myocardial ischemia. Current therapeutic methods for IR injury have limitations, and nanotechnology, particularly zinc oxide nanoparticles (ZnO NPs), offers new approaches for disease diagnosis and treatment. In this study, we investigated the protective and anti-apoptotic effects of ZnO NPs in liver ischemia-reperfusion (IR) injury in rats. Methods Forty-eight male rats were divided into six groups: sham, ZnO5, ZnO10, ischemia-reperfusion (IR), IR+ZnO5, and IR+ZnO10. The protective effect of ZnO NPs was evaluated by liver enzymes (AST, ALT, Bilirubin, ALP), biochemical (TAC, TNF-α, and MDA), molecular examinations (Bcl2, BAX), and histopathological evaluations (H&E, TUNEL). Results Pre-treatment with ZnO5 and ZnO10 improved hepatic function in IR liver injury, attenuated the levels of oxidants (P = 0.03) and inflammatory mediators, and reduced apoptosis (P = 0). ZnO10 was found to have a greater effect on ischemic reperfusion injury than ZnO5 did. Histopathological examination also showed a dose-dependent decrease in alterations in the IR+ZnO5 and IR+ZnO10 groups. Conclusion Administration of ZnO5 and ZnO10 improved liver function after IR. The findings of this study suggest that ZnO NPs have a protective effect against oxidative stress and apoptosis in liver ischemia-reperfusion injury in rats. These results may have important implications for developing advanced methods in ischemia-reperfusion treatment.

Abstract
The global burden of chronic liver disease (CLD) is substantial. Due to the limited indication of and accessibility to antiviral therapy in viral hepatitis and lack of effective pharmacological treatment in nonalcoholic fatty liver disease, the beneficial effects of antidiabetics and non-antidiabetics in clinical practice have been continuously investigated in patients with CLD. In this narrative review, we focused on non-antidiabetic drugs, including ursodeoxycholic acid, silymarin, dimethyl4,4'-dimethoxy-5,6,5',6'-dimethylenedixoybiphenyl-2,2'-dicarboxylate, L-ornithine L-aspartate, branched chain amino acids, statin, probiotics, vitamin E, and aspirin, and summarized their beneficial effects in CLD. Based on the antioxidant, anti-inflammatory properties, and regulatory functions in glucose or lipid metabolism, several non-antidiabetic drugs have shown beneficial effects in improving liver histology, aminotransferase level, and metabolic parameters and reducing risks of hepatocellular carcinoma and mortality, without significant safety concerns, in patients with CLD. Although the effect as the centerpiece management in patients with CLD is not robust, the use of these non-antidiabetic drugs might be potentially beneficial as an adjuvant or combined treatment strategy.

Abstract
Dimethyl dimethoxy biphenyl (DDB) dicarboxylate has been applied as a therapeutic modality for curing liver diseases, particularly hepatitis virus. The objective of this study was to assess the protective potential against Triton X-100 induced abnormal fat metabolism in addition to anti-inflammatory, analgesic, and antipyretic effects of DDB. The anti-inflammatory, antinociceptive, and antipyretic of DDB were investigated through induction of paw edema, pain, and fever in experimental rats. DDB decreased cholesterol and triglyceride contents. DDB resulted in inhibition of inflammation, nociception, and fever in the experimental models. DDB improved lipid profile, as evidence of hypolipidemic potential. It also showed anti-inflammatory, analgesic, and antipyretic properties.

Abstract
Backgrounds/Aims Steatohepatitis related to metabolic syndrome is a chronic liver disease prevalent in patients not only with non-alcoholic steatohepatitis but also with alcoholic liver disease and chronic viral hepatitis. On the other hand, there is limited data on the effects of hepatotonic agents in these patients. Therefore, this study evaluated the efficacy of a combined hepatotonic agent in this population. Methods Thirty-three adults with chronic hepatitis and one or more components of metabolic syndrome were assigned randomly to receive biphenyl dimethyl dicarboxylate/ursodeoxycholic acid or a placebo for 24 weeks. The primary outcome was the normalization of ALT (≤40 U/L). The secondary outcomes were the change in controlled attenuation parameter, transient elastography, and Chronic Liver Disease Questionnaire score. Results The 33 patients were assigned randomly to two groups. Eight (50%) of 16 patients who received the intervention drug showed the normalization of ALT, whereas only one (6%) of 17 patients in the placebo group did so. In contrast, the change in controlled attenuation, transient elastography, and Chronic Liver Disease Questionnaire were similar in the two groups. ALT was changed significantly during the four assessment periods, and this change was affected by the group. The interaction between the group and time was also significant. AST was changed significantly during the same period. This change was not affected by the group. Conclusions Biphenyl dimethyl dicarboxylate/ursodeoxycholic acid combination reduced ALT in chronic liver disease related to metabolic syndrome. On the other hand, there is no evidence that this leads to improved hepatic steatosis and fibrosis within 6 months.

Abstract
Introduction Stress is a well-known factor for inflammation in diverse organs/tissues. Stress also leads to liver injury, which was supported by clinical observations and animal studies. We herein investigated the hepatoprotective property of an herbal formula (called as CGplus) consisting of Artemisia gmelinii Weber ex Stechm. (syn, Artemisia iwayomogi Kitamura), Wurfbainia villosa var. xanthioides (Wall. ex Baker) Skornick. & A.D.Poulsen (syn, Amomum xanthioides Wallich), and Salvia miltiorrhiza Bunge against stress-induced hepatic damage. Methods Male BALB/c mice were orally administered water extract of CGplus (0, 50, 100, or 200 mg/kg) daily for 5 days, and then subjected to immobilization stress for 6 h on the 5th day. Results Acute immobilization stress elevated remarkably serum concentrations of stress hormones (corticosterone and adrenaline) and two hepatic injury parameters (ALT and AST), while these alterations were significantly attenuated by the administration of CGplus. The increases of oxidative parameters (ROS, NO, lipid peroxidation, and protein carbonyl) and deviation of IL-1β and IL-10 in opposite directions in hepatic tissues were significantly normalized by CGplus. Pre-treatment with CGplus also notably ameliorated the abnormal activation of toll-like receptor 4 (TLR4), CD14, and lipopolysaccharide-binding protein (LPB) as well as infiltration of neutrophils in hepatic tissues. Conclusion These results suggest that an herbal formula (CGplus) derived from traditional pharmaceutical theory has a potent protective effect against stress-induced hepatic injury via regulation of pro- (IL-1β) and anti-inflammatory (IL-10) cytokines.

Abstract
BACKGROUND AND AIM Ischemia/reperfusion (I/R) injury in the liver occurs after a prolonged period of ischemia followed by restoration of hepatic blood perfusion. During the surgery of abdominal aorta, I/R injury causes damage to lower extremities and many organs, especially liver. The antioxidant and tumor necrosis factor-alpha (TNF-α) suppression effects of topiramate (TPM) have been reported in several studies. We evaluated the potential protective effect of TPM on cellular damage in liver tissue during I/R injury. MATERIALS AND METHODS Thirty male Wistar albino rats were divided into three groups: Control, I/R, and I/R plus TPM (I/R + TPM) groups. Laparotomy without I/R injury was performed in the control group. After laparotomy, cross-ligation of infrarenal abdominal aorta was applied for 2 h in I/R groups that was followed by 2 h of reperfusion. TPM (100 mg/kg/day) was orally administrated to the animals in the I/R + TPM group for seven consecutive days before I/R procedure. RESULTS The I/R group's TNF-α and interleukin-6 (IL-6) levels were significantly higher than those of the control (P = 0.010; P = 0.002) and I/R + TPM groups (P = 0.010; P = 0.002, respectively). Asymmetric dimethyl arginine (ADMA) levels of I/R group were higher than the control (P = 0.015) and I/R + TPM groups. I/R caused serious histopathological damage to liver tissue; however, TPM led to very low histopathological changes. CONCLUSION Our data demonstrated that TPM treatment prominently decreases the severity of liver I/R injury. TPM pretreatment may have preventive effects on liver injury via I/R during intra-abdominal surgery.

Abstract
Ischemia and reperfusion (IR) injury remains one of the major problems in liver surgery and transplantation, which determines the viability of the hepatic tissue after resection and of the grafted organ. This review aims to elucidate the mechanisms involved in IR injury of the liver in rodent experimental studies and the preventative methods and pharmacologic agents that have been applied. Many time- and percentage-related liver IR injury rodent models have been used to examine the pathophysiological mechanisms and the parameters implicated with different morbidity, mortality, and pathology findings. The most preferred experimental rodent model of liver IR is the induction of 70% IR for 45 min, which is associated with almost 100% survival. In this model, plasma levels of several parameters such as alanine transaminase, aspartate aminotransferase, gamma-glutamyltransferase, endothelin-1, malonodialdehyde, tumor necrosis factor α, interleukin 1b, inducible nitric oxide synthase, and caspases are increased. The increase of caspases is associated with the initiation of hepatic cellular apoptosis. The main injuries observed 24 h after reperfusion are nuclear pyknosis, cytoplasmic hypereosinophilia, severe necrosis, and loss of intercellular borders. Both ischemic pre- and post-conditioning preventative methods and pharmacologic agents are successfully applied to alleviate the IR injuries. The selection of the time- and percentage-related liver IR injury rodent model and the potential preventative method should be related to the clinical question being answered.

Abstract
OBJECTIVE To study the effect of oral administration of dimethyl dimethoxy biphenyl dicarboxylate (DDB) on adjusting angiogeneic/inflammatory mediators and ameliorating the pathology of bones in rats with collagen-induced arthritis (CIA). METHODS Wistar rat model of CIA was set up using bovine collagen type II. Fifty rats were divided into five groups randomly: normal, CIA model, DDB treatment, methotrexate (MTX) treatment, and combined DDB+MTX treatment. Ankle joints of rats were imaged with digital X-ray machine to show the destruction of joints. Fore and hind paw and knee joints were removed above the ankle joint then processed for haematoxylin and eosin staining. Plasma levels of vascular endothelial growth factor (VEGF), platelet derived growth factor, interleukin-8 (IL-8), IL-4, tumor necrosis factor α (TNF-α), and cyclooxygenase-2 (COX-2) were quantified by enzyme-linked immunosorbent assay. Nitric oxide levels were detected by Griess reagent. RESULTS Compared with the CIA model group, a remarkable reduction in various angiogenic (VEGF and IL-8) and inflammatory mediators (TNF-α, IL-4 and COX-2) after treatment with DDB either alone or combined with MTX P<0.05 or P<0.01). Histopathological and X-ray findings were confirmatory to the observed DDB anti-arthritic effect. The DDB-treated group showed amelioration in signs of arthritis which appeared essentially similar to normal. CONCLUSION Our data shed light on the therapeutic efficacy of DDB in experimental rheumatoid arthritis (RA) compared with a choice drug (MTX) and it may be offered as a second-line drug in the treatment of RA.

Abstract
Molecular hydrogen has been proven effective in ameliorating cerebral ischemia/reperfusion (I/R) injury by selectively neutralizing reactive oxygen species. Lactulose can produce a considerable amount of hydrogen through fermentation by the bacteria in the gastrointestinal tract. To determine the neuroprotective effects of lactulose against cerebral I/R injury in rats and explore the probable mechanisms, we carried out this study. The stroke model was produced in Sprague-Dawley rats through middle cerebral artery occlusion. Intragastric administration of lactulose substantially increased breath hydrogen concentration. Behavioral and histopathological verifications matched biochemical findings. Behaviorally, rats in the lactulose administration group won higher neurological scores and showed shorter escape latency time in the Morris test. Morphologically, 2,3,5-triphenyltetrazolium chloride showed smaller infarction volume; Nissl staining manifested relatively clear and intact neurons and TUNEL staining showed fewer apoptotic neurons. Biochemically, lactulose decreased brain malondialdehyde content, caspase-3 activity, and 3-nitrotyrosine and 8-hydroxy-2-deoxyguanosine concentration and increased superoxide dismutase activity. The effects of lactulose were superior to those of edaravone. Lactulose orally administered activated the expression of NF-E2-related factor 2 (Nrf2) in the brain as verified by RT-PCR and Western blot. The antibiotics suppressed the neuroprotective effects of lactulose by reducing hydrogen production. Our study for the first time demonstrates a novel therapeutic effect of lactulose on cerebral ischemia/reperfusion injury and the probable underlying mechanisms. Lactulose intragastrically administered possessed neuroprotective effects on cerebral I/R injury in rats, which could be attributed to hydrogen production by the fermentation of lactulose through intestinal bacteria and Nrf2 activation.

Abstract
High fructose consumption is currently linked to metabolic disorders including insulin resistance and dyslipidemia as well as hepatic steatosis. Dimethyl dimethoxy biphenyl dicarboxylate (DDB) is a hepatoprotectant with antioxidant and anti-inflammatory properties. The aim of this study therefore is to evaluate the effect of DDB on high fructose-induced metabolic disturbances and hepatic steatosis in a rat model. Male Wistar rats were allocated into three groups: control, fructose-fed (10% in drinking water and 10% in diet), and fructose-fed DDB (300 mg/kg, orally)-treated groups. Rats were fed a high-fructose diet for 6 weeks, while DDB was administered for an additional 2 weeks. High-fructose consumption elevated serum glucose and insulin levels and impaired oral glucose tolerance test, revealing insulin resistance. It also increased serum triglycerides and alanine aminotransferase as well as visceral fat content and decreased serum high-density lipoprotein. Additionally, histopathological examination revealed that high fructose intake induced hepatic steatosis. These alterations were associated with increased serum uric acid as well as hepatic content of malondialdehyde and nitric oxide (NO) in addition to overexpression of inducible NO synthase (iNOS). DDB administration significantly ameliorated the high fructose-induced hepatic and metabolic alterations. In conclusion, DDB ameliorates high fructose-induced metabolic disorders and hepatic steatosis in rats. Such protection is, at least in part, due to the inhibition of lipid peroxidation, decrease in iNOS overexpression, and reduction of elevated uric acid.
