Abstract
Mycotoxicoses are usually a consideration in large animal species but can affect companion animals as well. Due to increasing interest and the ease of using rabbits as laboratory models, a growing number of published experimental studies discuss the effects of various mycotoxins on this species. However, the available evidence is fragmented and heterogeneous, and has not recently been collated in a review, to my knowledge. Although mycotoxicoses in rabbits are typically subclinical, clinical signs can include weight loss, anorexia, gastrointestinal disorders, stunted growth, reproductive abnormalities, and susceptibility to infections. An antemortem diagnosis typically relies on a comprehensive clinical history, and assessment of clinical signs and relevant laboratory findings, with confirmation of exposure achieved through the measurement of mycotoxin concentrations in feed or target organs. My review focuses on the clinicopathologic and histopathologic effects of the mycotoxins most important in rabbits, including fumonisins, ochratoxins, aflatoxins, trichothecenes, and zearalenone. This review offers a thorough overview of the effects of mycotoxins in rabbits, serving as a one-stop resource for veterinary practitioners, diagnosticians, and researchers.

Assessment of the effect of sodium tetraborate on oxidative stress, inflammation, and apoptosis in lead-induced nephrotoxicity. Drug Chem Toxicol 2024:1-13. [PMID: 38804252 DOI: 10.1080/01480545.2024.2358067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Accepted: 05/16/2024] [Indexed: 05/29/2024]
Abstract
Exposure to Pb, a toxic heavy metal, is a risk factor for renal damage. Borax, an essential trace element in cellular metabolism, is a naturally occurring compound found in many foods. This study investigated the effects of sodium tetraborate (ST), a source of borax, on renal oxidative stress and inflammation in rats exposed to Pb. Wistar Albino rats (n = 24) were divided into four groups: Control (0.5 mL, i.p. isotonic), Pb (50 mg/kg/day/i.p.), ST (4.0 mg/kg/day/oral), and Pb + ST groups. At the end of the five-day experimental period, kidney tissue samples were obtained and analyzed. Histopathologically, the Pb-induced damage observed in the Pb group improved in the Pb + ST group. Immunohistochemically, Pb administration increased the expression of inducible nitric oxide synthase, cyclooxygenase-2, and caspase-3. When evaluated biochemically, Pb application inhibited catalase and glutathione peroxidase (GSH-Px) enzyme activities and activated superoxide dismutase enzyme activity. An increase in malondialdehyde levels was considered an indicator of damage. ST application increases glutathione peroxidase enzyme activity and decreased malondialdehyde levels. These results indicate that ST might play a protective role against Pb-induced renal damage via the upregulation of renal tissue antioxidants and cyclooxygenase-2, inducible nitric oxide synthase, and caspase-3 immunoexpression.

Abstract
This study was aimed at investigating the ability of extract of Annona muricata (AM) flower-petals in ameliorating the toxic effects of acetaminophen on the kidneys of albino rats. The biochemical results showed a marked increase in AM 200 mg (32.84 ± 0.14) and AM 400 mg (32.64 ± 0.78). Increase levels of total protein in AM 200 mg (77.00 ± 5.65) displays nephroprotective potential of the flower extract. Reduction of renal activities of serum urea in AM 400 mg group (6.41 ± 0.22) indicates its protective potency against acetaminophen induced kidney damage. Increased activities of SOD levels at 200 mg (4.97 ± 0.05) and CAT levels at 200 mg (23.39 ± 1.13). This study showed that A. muricata has good prospects of being a nephroprotective drug candidate.

Food Addit Contam Part A Chem Anal Control Expo Risk Assess 2024; 41:438-459. [PMID: 38408272 DOI: 10.1080/19440049.2024.2316750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 02/05/2024] [Indexed: 02/28/2024]
Abstract
This review explores the repercussions of mycotoxin contamination in food and feed, emphasising potential threats to agriculture, animal husbandry and public health. The primary objective is to make a comprehensive assessment of the neurotoxic consequences of mycotoxin exposure, an aspect less explored in current literature. Emphasis is placed on prominent mycotoxins, including aflatoxins, fumonisins, zearalenone (ZEA) and ochratoxins, known for inducing acute and chronic diseases such as liver damage, genetic mutation and cancer. To elucidate the effects, animal studies were conducted, revealing an association between mycotoxin exposure and neurological damage. This encompasses impairments in learning and memory, motor alterations, anxiety and depression. The underlying mechanisms involve oxidative stress, disrupting the balance between reactive oxygen species (ROS) and antioxidant capacity. This oxidative stress is linked to neuronal damage, brain inflammation, neurochemical imbalance, and subsequent behavioural changes. The review underscores the need for preventive measures against mycotoxin exposure. While complete avoidance is ideal, exploration into the potential use of antioxidants as a viable solution is discussed, given the widespread contamination of many food products. Specifically, the protective role of natural compounds, such as polyphenols, is highlighted, showcasing their efficacy in mitigating mycotoxicosis in the central nervous system (CNS), as evidenced by findings in various animal models. In summary, countering mycotoxin-induced neurotoxicity requires a multifaceted approach. The identified natural compounds show promise, but their practical use hinges on factors like bioavailability, toxicity and understanding their mechanisms of action. Extensive research is crucial, considering the diverse responses to different mycotoxins and neurological conditions. Successful implementation relies on factors such as the specific mycotoxin(s) involved and achievable effective concentrations. Further research and clinical trials are imperative to establish the safety and efficacy of these compounds in practical applications.

Abstract
Global aflatoxin contamination of agricultural commodities is of the most concern in food safety and quality. This study investigated the hepatoprotective effect of 80% methanolic leaf extract of Annona senegalensis against aflatoxin B1 (AFB1)-induced toxicity in rats. A. senegalensis has shown to inhibit genotoxicity of aflatoxin B1 in vitro. The rats were divided into six groups including untreated control, aflatoxin B1 only (negative control); curcumin (positive control; 10 mg/kg); and three groups receiving different doses (100 mg/kg, 200 mg/kg, and 300 mg/kg) of A. senegalensis extract. The rats received treatment (with the exception of untreated group) for 7 days prior to intoxication with aflatoxin B1. Serum levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, and creatinine were measured. Hepatic tissues were analysed for histological alterations. Administration of A. senegalensis extract demonstrated hepatoprotective effects against aflatoxin B1-induced toxicity in vivo by significantly reducing the level of serum aspartate aminotransferase and alanine aminotransferase and regenerating the hepatocytes. No significant changes were observed in the levels of alkaline phosphatase, lactate dehydrogenase, and creatinine for the AFB1 intoxicated group, curcumin+AFB1 and Annona senegalensis leaf extract (ASLE)+AFB1 (100 mg/kg, 200 mg/kg, and 300 mg/kg body weight [b.w.]) treated groups. Annona senegalensis is a good candidate for hepatoprotective agents and thus its use in traditional medicine may at least in part be justified.Contribution: The plant extract investigated in this study can be used in animal health to protect the organism from toxicity caused by mycotoxins.

Abstract
This study was conducted to investigate the protective potential of a pharmaceutically formulated capsule of artichoke leaf powder (ArLP) against aflatoxin B1 (AFB1)-induced hepatotoxicity in male albino rats. In the 42-day experiment, rats were divided into five equal groups: (i) control, treated with sterile water, (ii) treated with 4% DMSO as AFB1 vehicle, (iii) ArLP of 100 mg kg-1 bw, (iv) AFB1 of 72 µg kg-1 bw, and (v) AFB1 plus ArLP. Exposure of rats to AFB1 resulted in hepatotoxicity as manifested by the intensification of oxidative stress, production of free radicals and significant increase in the activity levels of liver function enzymes relative to the control. Significant reductions in both the enzymatic and non-enzymatic antioxidant markers as well as histopathological abnormalities in liver tissues were also observed. Notably, the combined administration of ArLP with AFB1 clearly reduced AFB1-mediated adverse effects leading to the normalization of most of these parameters back to control levels. These findings clearly highlight the potential benefits of artichoke dietary supplements as a safe and natural solution in counteracting the adverse hepatotoxic effects conferred by AFB1 exposure. Further research is warranted to fully dissect the biochemical and molecular mechanism of action of the observed artichoke-mediated hepatoprotection.

Abstract
One particularly harmful mycotoxin, aflatoxin B1 (AFB1), usually triggers liver toxicity and oxidative stress in both humans and other mammals. Luteolin (LUTN), a popular active phytochemical molecule, exhibits a strong antioxidant potential. The purpose of this investigation was to explore the potential molecular mechanism in rats and determine if LUTN exhibits protective benefits against AFB1-induced hepatotoxicity. Random selection was used to determine the four treatment groups, each consisting of 24 rats (n = 6). Physiological saline was administered to group 1 (CONT); group 2 received LUTN for a dosage of 50-mg/kg BW. AFB1 was administered to group 3 for a dosage of 0.75-mg/kg BW, and AFB1 with LUTN was given to group 4 at the same dosages mentioned in the previous groups. Rats intoxicated with AFB1 alterations of hepatic transaminases, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), displayed periportal mononuclear cell infiltrations, disorganized lobular architecture, and dispersed necrotic cells in their liver tissues. By reducing serum biochemical levels of the hepatic transaminases ALT and AST brought on by AFB1 exposure, our results demonstrated that LUTN treatment considerably restored liver injury. Through lowering the production of malondialdehyde (MDA) and reactive oxygen species (ROS), as well as by boosting the activity of the antioxidant enzyme catalase (CAT) and superoxide dismutase (SOD), LUTN mitigated the oxidative stress brought on by AFB1. Our findings showed that LUTN significantly reversed the liver damage caused by AFB1. When considered as a whole, LUTN may protect the liver from damage brought on by AFB1 by acting as a potential mitigator and may aid in the creation of cutting-edge therapies to treat liver illnesses in humans and/or animals.

Abstract
Aflatoxin B1 (AFB1) is a mycotoxin synthesised as a secondary metabolite by members of the Aspergillus species contaminating agricultural produce. Aspergillus species thrive in tropical climes, endemic to malaria. Artemisinin-based combination therapies (ACTs) effectively treat and prevent malaria recrudescence; Coartem (COA) is an ACT whose toxicity is evident. Although there are scanty studies on COA toxicity, the scientific literature is replete on AFB1 toxic effects -including carcinogenicity. The current research investigates AFB1 and COA toxicity in experimental Wistar rats' hepatorenal systems. Thirty albino rats were randomly grouped into five cohorts (n = 6) and treated as follows: Group I: Untreated control (2 mL/kg of corn oil); group II: AFB1 alone (70 μg/kg); group III: COA alone (5 mg/kg); group IV: COA and a low dose of AFB11 (5 mg/kg & 35 μg/kg); while Group V: COA and a high dose AFB12 (5 mg/kg & 70 μg/kg) by gavage. Our results show that exposure to AFB1 and COA significantly (p < 0.05) reduced superoxide dismutase, catalase, glutathione peroxidase, and glutathione-S-transferase activities, besides reduced glutathione and total sulfhydryl groups level. Reactive oxygen and nitrogen species, lipid peroxidation, 8-hydroxy-2'-deoxyguanosine, nitric oxide, xanthine oxidase, and myeloperoxidase levels were increased (p < 0.05) in rats co-treated with COA and AFB1. Cell death was aggravated in COA and AFB1 groups, exemplified by increased Caspase-3 and 9 activities and alterations in the typical histological features of experimental rats' livers and kidneys. Finally, rats co-treated with AFB1 and COA experienced increased hepatorenal dysregulation, oxidative and inflammatory tissue damage, and apoptotic cell death. All the observed systemic perturbations occurred dose-dependently. It is crucial, therefore, to prevent AFB1 dietary contaminations during COA therapeutic regimen due to increased pathophysiological damage exerted on experimental rat liver and kidneys, as evidenced in this study.

Abstract
The protective effect of collagen peptide from Acaudina molpadioides (Amp) on acute kidney injury (AKI) in mice and its mechanism were explored. The results showed that Amp-fed could effectively improve the renal mass index and histopathological morphology. The levels of serum creatinine and urea nitrogen decreased significantly, while the antioxidant enzyme catalase (CAT) and superoxide dismutase (SOD) increased significantly in Amp-fed groups. Western blot results disclosed that Amp significantly upregulates the levels of heme oxygenase-1 (HO-1), Nrf2, p-PI3K, and p-AKT in the kidney. In addition, Amp could significantly downregulate the levels of nuclear factor NF-kappa-B (NF-κB), tumor necrosis factor α (TNF-α), inflammatory cytokines interleukin 6 (IL-6) and interleukin 1β (IL-1β). These findings provide evidence that Amp plays a protective role in AKI via attenuation of oxidative stress and inflammation mediated by PI3K/AKT/Nrf2 and PI3K/AKT/NF-κB pathways. This study laid a foundation for the application of Amp in the prevention of AKI.

Apigeninidin-rich Sorghum bicolor (L. Moench) extracts suppress A549 cells proliferation and ameliorate toxicity of aflatoxin B1-mediated liver and kidney derangement in rats. Sci Rep 2022; 12:7438. [PMID: 35523904 PMCID: PMC9076626 DOI: 10.1038/s41598-022-10926-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Accepted: 04/08/2022] [Indexed: 02/07/2023] Open
Abstract
Sorghum bicolor plant has a high abundance of 3-deoxyanthocyanins, flavonoids and other polyphenol compounds that have been shown to offer numerous health benefits. Epidemiological studies have linked increased intake of S. bicolor to reduced risk of certain cancer types, including lung adenocarcinoma. S. bicolor extracts have shown beneficial effects in managing hepatorenal injuries. This study investigated the cytotoxic potential of three apigeninidin-rich extracts of S. bicolor (SBE-05, SBE-06 and SBE-07) against selected cancer cell lines and their ameliorative effect on aflatoxin B1 (AFB1)-mediated hepatorenal derangements in rats. We observed that, among the three potent extracts, SBE-06 more potently and selectively suppressed the growth of lung adenocarcinoma cell line (A549) (IC50 = 6.5 μg/mL). SBE-06 suppressed the expression of STAT3 but increased the expression of caspase 3. In addition, SBE-05, SBE-06 and SBE-07 inhibited oxidative and nitrosative stress, inflammation, and apoptosis and preserved the histoarchitectural networks of the liver and kidney of rats treated with AFB1. These in vitro and in vivo studies indicate the potential of these cheap and readily accessible extracts for cancer therapy and as chemo-preventive agents in preventing aflatoxin-related health issues.

Onderstepoort J Vet Res 2022; 89:e1-e6. [PMID: 35384682 PMCID: PMC8991193 DOI: 10.4102/ojvr.v89i1.1968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 12/18/2021] [Accepted: 01/25/2022] [Indexed: 11/01/2022] Open
Abstract
Aflatoxins are potent hepatotoxic and carcinogenic secondary metabolites produced by toxigenic fungi. The present study investigated the protective effect of methanolic leaf extracts of Monanthotaxis caffra (MLEMC) against aflatoxin B1-induced toxicity in male Sprague-Dawley rats. The rats were randomly divided into 6 groups of 8 animals each. Five groups were administered orally for seven days with three different concentrations of MLEMC (100 mg/kg, 200 mg/kg and 300 mg/kg), curcumin (10 mg/kg) or vehicle (25% propylene glycol). The following day, these groups were administered 1 mg/kg b.w. of aflatoxin B1 (AFB1). The experiment was terminated three days after administration of AFB1. Group 6 represented untreated healthy control. Serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, creatinine and liver histopathology were evaluated. Methanolic leaf extracts of M. caffra decreased the levels of aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase and creatinine in the sera of rats as compared with the AFB1 intoxicated group. Co-administration of MLEMC improved the histological characteristics of the hepatocytes in contrast to the AFB1 treated group, which had mild to severe hepatocellular injuries including bile duct proliferation, bile duct hyperplasia, lymphoplasmacytic infiltrate and fibrosis. Extracts of M. caffra were beneficial in mitigating the hepatotoxic effects of AFB1 in rats by reducing the levels of liver enzymes and preventing hepatic injury.

Nikhat S, Fazil M. History, phytochemistry, experimental pharmacology and clinical uses of honey: A comprehensive review with special reference to Unani medicine. JOURNAL OF ETHNOPHARMACOLOGY 2022; 282:114614. [PMID: 34508800 DOI: 10.1016/j.jep.2021.114614] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2021] [Revised: 08/19/2021] [Accepted: 09/05/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Honey is one of the most popular functional foods, speculated to be in use since the advent of human civilization. Its health-protective activity is endorsed by many religions and traditional medicines. In Unani medicine, honey is prescribed for many health conditions as wound-healing, anti-inflammatory, anti-diabetic, etc. In the present era, honey is gaining popularity over sugar for its myriad health benefits and low glycemic index. This review attempts to provide a comprehensive account of the biological activities and potential therapeutic uses of honey, with scientific evidence. METHODOLOGY In this paper, we have provided a comprehensive overview of historical uses, types, physical characteristics, bioactive constituents and pharmacological activities of honey. The information was gathered from Classical Unani textbooks and leading scientific databases. There is a plethora of information regarding various therapeutic activities of honey, and it is daunting to draw practical conclusions. Hence, in this paper, we have tried to summarize those aspects which are most relevant to clinical application. OBSERVATIONS AND CONCLUSIONS Many important bioactive constituents are identified in different honey types, e.g. phenolics, proteins, vitamins, carbohydrates, organic acids, etc., which exert important biological activities like anti-microbial, wound healing, immunomodulatory, anti-toxin, antioxidant, and many others. Honey has the potential to alleviate many lifestyle disorders, mitigate the adverse effects of drugs and toxins, and also provide healthy nutrition. Although conclusive clinical evidence is not available, yet honey may potentially be a safer alternative to sucrose for diabetic patients.

Caffeic acid protects against DNA damage, oxidative and inflammatory mediated toxicities, and upregulated caspases activation in the hepatorenal system of rats treated with aflatoxin B 1. Toxicon 2022; 207:1-12.

Abstract
Aflatoxicosis can induce largescale toxicities in predisposed populations. Food fortification with adequate antioxidant sources may reduce the toxic burden from aflatoxicosis. We examined the individual and combined effect of Caffeic acid (CA) on the aflatoxin B1 (AFB1)-induced hepatic and renal injury in male rats. Five experimental rat cohort (n = 6) consisting of the control (2 mL/kg corn oil), AFB1 alone (50 μg/kg), CA alone (40 mg/kg), AFB1+CA1 (50 μg/kg + 20 mg/kg) and AFB1+CA2 (50 μg/kg + 40 mg/kg) were so treated for 28 consecutive days. Upon sacrifices, diagnostic markers of hepatorenal functions, oxidative stress, inflammation, oxidative deoxyribonucleic acid -DNA-damage and apoptosis were analysed. Our results showed that CA reduced AFB1-induced toxicities in rats' liver and kidneys by significantly increasing (p < 0.05) endogenous antioxidant and the anti-inflammatory IL-10 level. Caffeic acid simultaneously reduced hepatic and renal dysfunction biomarkers in the serum, oxidative stress, and lipid peroxidation levels. Besides, CA diminished reactive oxygen and nitrogen species, inflammatory nitric oxide levels, interleukin-1 β and the activities of xanthine oxidase and myeloperoxidase. Additionally, CA reduced DNA damage and caspase-mediated apoptotic responses and preserved the cytoarchitecture of rats' liver and kidneys treated with AFB1. These data suggest that CA can be used as a food additive to mitigate AFB1-induced toxicity in the examined organs.

Abstract
OBJECTIVES The current tools for the management of diabetes mellitus (DM) do not prevent its development or complications, so investigations into promising new treatments, for example, honey-royal jelly (H-RJ) mixtures, are needed. This study was conducted to evaluate the effect of royal jelly on DM by measuring the biochemical parameters (fasting blood glucose and glycated hemoglobin [HbA1c]) accompanying streptozotocin (i.p. 75 mg/kg once)-induced type 1 DM (T1DM) in rats. Other objectives were to evaluate the effects of H-RJ on lipid parameters. METHODS Ten healthy control male Sprague-Dawley rats (120-150 g) were compared to untreated T1DM (n = 10), metformin-treated T1DM (n = 10), and H-RJ-treated T1DM rats (n = 10) on plasma and whole-blood glycemic control indices (fasting blood glucose, HbA1c %, insulin, and insulin resistance) and plasma lipid profile (triglycerides [TGs] and total, low-density lipoprotein -, high-density lipoprotein -, and very low-density lipoprotein [VLDL]-cholesterol). Diabetes was induced by a single intraperitoneal injection of streptozotocin (SZT) at 75 mg/kg body weight (BW). The T1DM-H-RJ rat group received daily RJ (100 mg/kg BW). Parametric data are presented as mean ± SD and were analyzed for comparison using one-way ANOVA in SPSS software. RESULTS H-RJ normalized glycemic control indices, but its effect on lipid parameters was variable. H-RJ and metformin had comparable effects. The H-RJ treatment caused a significant reduction in plasma VLDL-C content in comparison to the control treatment and metformin. The limitation of this study is that it was restricted to T1DM and did not involve type 2 DM. In addition, the study was limited to male Sprague-Dawley rats, with no females. CONCLUSION The H-RJ mixture is a promising antidiabetic alternative medicine. It effectively reduces VLDL-C and TG in diabetic rats.

The roles of strawberry and honey phytochemicals on human health: A possible clue on the molecular mechanisms involved in the prevention of oxidative stress and inflammation. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 86:153170. [PMID: 31980299 DOI: 10.1016/j.phymed.2020.153170] [Citation(s) in RCA: 42] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 12/19/2019] [Accepted: 01/06/2020] [Indexed: 05/28/2023]
Abstract
BACKGROUND Oxidative stress and inflammation contribute to the etiopathogenesis of several human chronic diseases, such as cancer, diabetes, cardiovascular diseases and metabolic syndrome. Besides classic stimuli, such as reactive oxidant species, endotoxins (i.e., bacteria lipopolysaccharide), cytokines or carcinogens, oxidative stress and inflammation can be triggered by a poor diet and an excess of body fat and energy intake. Strawberry and honey are common rich sources of nutrients and bioactive compounds, widely studied for their roles exerted in health maintenance and disease prevention. PURPOSE This review aims to summarize and update the effects of strawberry and honey against oxidative stress and inflammation, with emphasis on metabolism and on the main molecular mechanisms involved in these effects. METHODS A wide range of literature, published in the last 10 years, elucidating the effects of strawberry and honey in preventing oxidative stress and inflammation both in vitro (whole matrix and digested fractions) and in vivo was collected from online electronic databases (PubMed, Scopus and Web of Science) and reviewed. RESULTS Strawberry and honey polyphenols may potentially prevent the chronic diseases related to oxidative stress and inflammation. Several in vitro and in vivo studies reported the effects of these foods in suppressing the oxidative stress, by decreasing ROS production and oxidative biomarkers, restoring the antioxidant enzyme activities, ameliorating the mitochondrial antioxidant status and functionality, among others, and the inflammatory process, by modulating the mediators of acute and chronic inflammation essential for the onset of several human diseases. These beneficial properties are mediated in part through their ability to target multiple signaling pathways, such as p38 MAPK, AMPK, PI3K/Akt, NF-κB and Nrf2. CONCLUSIONS Available scientific literature show that strawberry and honey may be effective in preventing oxidative stress and inflammation. The deep evaluation of the factors that affect their metabolism as well as the assessment of the main molecular mechanisms involved are of extreme importance for the possible therapeutic and preventive benefit against the most common human diseases. However, published literature is still scarce so that deeper studies should be performed in order to evaluate the bioavailability of these food matrices and their effects after digestion.

Protective Effect of Thyme Honey against Valproic Acid Hepatotoxicity in Wistar Rats. BIOMED RESEARCH INTERNATIONAL 2021; 2021:8839898. [PMID: 33688502 PMCID: PMC7920727 DOI: 10.1155/2021/8839898] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Revised: 01/31/2021] [Accepted: 02/15/2021] [Indexed: 11/18/2022]
Abstract
Introduction Valproic acid is a medication most commonly used in the treatment of emotional and neurological depression, psychological imbalances, epilepsy, and bipolar disorder. Dark honey, like thyme honey, contains more antioxidant compounds than other samples. The purpose of this study was to evaluate the effect of thyme honey on the potential hepatic effects of valproic acid. Methods In this study, 48 male rats were randomly divided into 8 groups (n = 6): G1 (control): healthy rats (normal saline 0.9%), G2: thyme honey (1 g/kg), G3: thyme honey (2 g/kg dose), G4: thyme honey (3 g/kg dose), G5: VPA (500 mg/kg), G6: VPA (500 mg/kg) and thyme honey (1 g/kg), G7: VPA (500 mg/kg) and thyme honey (2 g/kg dose), and G8: VPA (500 mg/kg) and thyme honey (3 g/kg dose). Groups G1 to G5 received the drug for 28 days. On day 14, administration of thyme honey for G6 to G8 groups was carried out using gavage until day 28. VPA was administered one hour after honey. To carry out the biochemical evaluation, blood samples were collected from all the groups and their serums were used for MDA, TAC, and liver enzymes (AST, ALT, and GGT). Tissue samples of each rat were also removed for histological studies with hematoxylin-eosin and Masson's trichrome staining. Results The use of thyme honey significantly improved the histopathological parameters of the liver tissue, including hypertrophic degeneration and nucleus alteration, expansion of sinusoids, fibrosis and hepatic necrosis, and inflammation as well as hypertrophy of Kupffer cells. In the groups receiving VPA, the rate of lipid peroxidation increased, which indicates the destruction of the liver cell membrane due to drug consumption. TAC levels also increased following increase in thyme honey dosage (p ≤ 0.05). The results of liver enzyme analysis showed a decrease in AST and ALT levels in the G6 group and a decrease in GGT level in the G8 group (p ≤ 0.05). Conclusion Based on the results of this study, it seems that high percentage of antioxidants in thyme honey enabled it to improve hepatic complications and reduce the rate of hepatocellular destruction.

Abstract
Simple Summary Aflatoxins can affect hepatocytes, which results in a series of histological and ultrastructural changes to the cells. We investigated the hepatocellular alterations induced by aflatoxin B1 in rats. Interestingly, we observed several histopathological and ultrastructural alterations in hepatocytes, including necrotic changes and massive vacuolar degeneration. Ultrastructural examinations of treated groups revealed damage to the sinusoidal endothelium, as well as aggregations of hyperactive Kupffer cells in the space of Disse and damaged telocytes. Our findings provide novel insights into the induction of a series of irreversible adverse effects on hepatocytes by aflatoxin B1. Based on our results, we suggest future investigations for the exploration of mechanistic pathways related to these induced hepatocellular alterations. Abstract Liver sinusoids are lined by fenestrated endothelial cells surrounded by perisinusoidal cells, Kupffer cells, and pit cells, as well as large granular lymphocytes. The functional ability of the liver cells can be substantially modified by exposure to toxins. In the current work, we assessed the histopathological and ultrastructural effects of a time-course exposure to aflatoxin B1 (AFB1) on the hepatic structures of rats. A total of 30 adult female Wistar rats were randomly divided into three groups: a control group, a group orally administered 250 µg/kg body weight/day of AFB1 for 5 days/week over 4 weeks, and a group that received the same AFB1 treatment but over 8 weeks. Histopathological and ultrastructural examinations of hepatocytes revealed massive vacuolar degeneration and signs of necrosis. Furthermore, the rat liver of the treated group exhibited damage to the sinusoidal endothelium, invasion of the space of Disse with hyperactive Kupffer cells, and some immune cells, as well as Ito cells overloaded with lipids. In addition, damaged telocytes were observed. Taken together, our results indicate that AFB1 induces irreversible adverse effects on the livers of rats.

Abstract
Chronic stress is linked to liver injury by increasing intestinal permeability to lipopolysaccharide (LPS), which in turn can result in systemic and liver inflammation and damage. Beneficial effect of honey in the prevention of liver injury has been shown in previous studies, but mechanisms underlying are still less known. Here, we examined the therapeutic impacts of honey on intestinal nuclear factor-κB (NF-κB; an important regulator of stress-induced immune and inflammatory responses) and ileal tight junction (TJ) proteins of claudin-1 and ZO-1, serum LPS, liver inflammation and oxidative markers of malondialdehyde (MDA), nitric oxide (NO), (erythroid-derived 2)-like 2 (Nrf2), tumor necrosis factor (TNF)-α and total antioxidant capacity (TAC) following chronic unpredictable mild stress (CUMS) using Western blotting, ELISA kit and spectrophotometry. Male rats were subjected to CUMS for 28 consecutive days. Honey (0.2 and 2 g/kg/day, by gavage) was administered pretreatment (10 days) and during stress. Honey reduced stress-induced LPS elevation by preventing reduction in the intestinal TJ proteins of claudin-1 and ZO-1, while did not affect NF-kB levels. In liver, honey significantly suppressed stress-induced increase in MDA, NO, TNF-α and Nrf2 expression and normalized TAC. Noteworthy, honey high-dose provoked a greater decrease in TNF-α, Nrf2 and LPS levels than honey low-dose. Together, our study indicated that honey protects against stress-induced liver damage by modulating at least two pathways; intestinal barrier protection via increased TJ protein complex expression, and hepatic TAC protection that may be involved in the inhibition of MDA, NO, TNF-α and Nrf2 expression.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disorder worldwide with no curative therapy. The aim of this study was to investigate the hepatoprotective effects of a novel Trihoney against biochemical and histological manifestations of NAFLD in hypercholesterolemic rabbits. Methodology. Forty-eight male New Zealand white (NZW) rabbits were grouped into normal diet (C), normal diet with 0.6 g/kg/day of Trihoney (C + H), 1% cholesterol diet (HCD), 1% cholesterol diet with 0.3 g/kg/day of Trihoney (HCD + H1), 1% cholesterol diet with 0.6 g/kg/day of Trihoney (HCD + H2), and 1% cholesterol diet with 2 mg/kg/day of atorvastatin (HCD + At.). Animals were sacrificed after 12 weeks of treatment. Serum lipids and liver function test (LFT) were measured prior to and at the endpoint of the experiment for total cholesterol (TC), low-density lipoprotein (LDL-c), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and total bilirubin (T. Bil.). Liver was processed for histopathology study. Liver homogenate was analysed for oxidative stress parameters: superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA). Results. Lipid analysis approved the induction of hypercholesterolemia. A significant elevation (p < 0.01) of serum AST and ALT levels showed by the HCD group was compared to C and C + H groups. Trihoney exhibited a significant reduction (p < 0.001) of AST and ALT compared to the HCD group. Likewise, AST and ALT reduced significantly in the HCD + At. group (p < 0.001). Trihoney supplementation induced significant (p < 0.05) enhancement of SOD and GPx activities. Atorvastatin treatment was associated with significant (p < 0.05) reduction of SOD and GPx activities in the liver. Trihoney and atorvastatin showed marked (p < 0.001) reduction of hepatic lipid peroxidation. Trihoney showed histological protection against progression of NAFLD to nonalcoholic steatohepatitis (NASH). Atorvastatin exhibited no beneficial impact on hepatic architecture. Conclusion. Trihoney was able to maintain normal liver function and showed hepatoprotection against progression of NAFLD to NASH probably through hypocholesterolaemic and antioxidant functions.

Abstract
The potential Aflatoxin B1 (AFB1) binding Lactobacillus fermentum (LC5/a) was used for in vivo AFB1 binding and detoxification in presence of chlorophyll (CL) in male Swiss albino mice. Mice were randomly divided into seven groups. The control groups (CL, AFB1 and LC5/a) received chlorophyll (250 μg/kg b.w), AFB1 (100 μg/kg b.w) and LC5/a (1 × 108 CFU) for 21 days. The treatment group (AFB1+LC5/a) received 100 μl of lyophilized bacterial suspension (1 × 108 CFU) 2 h before the AFB1 dosage (100μg/kg b.w). The chlorophyll mice group (CL + AFB1) was given single oral dose of CL (250 μg/kg b.w) before AFB1 dosage and last mice group received the combination of CL + LC5/a before the AFB1 dosage over a period of 21 days. Ballooning of cytoplasm and necrosis in liver was evident in histopathological examination of AFB1 mice group, while, marked improvement and nearly normal histology were seen in LC5/a and CL treated mice group. The levels of AST, ALT, GST, and SOD were increased in AFB1 mice group compared to LC5/a and CL treated mice group. Elevated levels of pro-inflammatory cytokines, TNF-α, IL-12, IL-6 (324, 506, 117.25 pg/ml) were observed in AFB1 treated mice serum compared to LC5/a and CL treated mice (249.54, 322.01 and 82.35 pg/ml). Thus, Lactobacillus fermentum LC5/a has certainly sequestered AFB1 from gastrointestinal tract besides regulating the production of pro-inflammatory cytokines.

Protective Effect of Low Molecular Weight Peptides from Solenocera crassicornis Head against Cyclophosphamide-Induced Nephrotoxicity in Mice via the Keap1/Nrf2 Pathway. Antioxidants (Basel) 2020; 9:antiox9080745. [PMID: 32823691 PMCID: PMC7465301 DOI: 10.3390/antiox9080745] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 08/11/2020] [Accepted: 08/11/2020] [Indexed: 12/11/2022] Open
Abstract
The major component of the Solenocera crassicornis head protein hydrolysates-fraction 1 (SCHPs-F1) are low molecular weight peptides (MW < 1 kDa). In this study, we investigated the potential renoprotective effects of SCHPs-F1 in a cyclophosphamide (CTX) toxicity mouse model. In brief, 40 male mice were randomly divided into 5 groups and received either saline or 80 mg/kg body weight (BW) CTX by intraperitoneal injection for 5 days, followed by either saline or SCHPs-F1 (100, 200, and 400 mg/kg BW) by intragastric administration for 15 days. SCHPs-F1 treatment significantly reversed the CTX-induced decreases in the levels of blood urea nitrogen (BUN), creatinine (CRE), and cytochrome P450 (CYP450), as well as the renal histological lesions. Furthermore, the results indicated that SCHPs-F1 potentially alleviated CTX-induced nephrotoxicity through mitigating inflammatory responses, oxidative stress, and apoptosis status of the kidneys, as evidenced by decreased levels of malondialdehyde (MDA), interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ and increased levels of total antioxidant capacity (T-AOC), catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Moreover, overexpression of pro-apoptotic proteins pair B-cell lymphoma-2 (Bcl-2)-associated X (Bax)/Bcl-2, cysteinyl aspartate specific proteinase (caspase)-3 and caspase-9 in renal tissues were suppressed by treatment with SCHPs-F1. In addition, the protein levels of the antioxidant factor nuclear factor erythroid-2 related factor 2 (Nrf2) and the expression levels of its downstream target genes heme-oxygenase (HO-1), glutamate-cysteine ligase modifier subunit (GCLM) and NAD(P)H dehydrogenase (quinone) 1 (NQO-1) were stimulated by treatment with SCHPs-F1 in the CTX-induced renal injury model. Taken together, our data suggested that SCHPs-F1 could provide a novel potential strategy in mitigating the nephrotoxicity caused by CTX.

Abstract
Aflatoxin B1 poses the greatest risk among the mycotoxins to target-organisms particularly human, however, no studies addressed the neurotoxicity of chronic exposure of aflatoxin. The oral dose level 1/600th of LD50 for 30, 60, and 90 days was used for three aflatoxin groups, respective to negative and vehicle control groups. Activity levels of brain antioxidants viz: superoxide dismutase, catalase, glutathione, and glutathione peroxidase significantly decreased in the three experimental durations in time-dependent trend, in contrast, lipid peroxidation showed a significant increase compared to controls. Significantly, chronic-dependent increase trend was noticed in the AF60 and AF90 group for acid phosphatase (16.1%, 35.2%), alkaline phosphatase (32.1%, 50.8%), aspartate aminotransferase (38.7%, 120.0%) and lactate dehydrogenase (30.6%, 42.1%) activities, respectively. However, a significant 23.7% decrease in the brain creatine kinase activity following 90 days of AFB1administration. Chronic administration of aflatoxin also causes alterations in activities of protein carbonyl with a maximum increase (twofold) after 90 days. Further, histopathological and immunohistochemical results confirmed time-related vasodilation, necrosis and astrocytes gliosis by high glial fibrillary acidic protein immunostaining in response to AFB1. These findings infer that long-term exposure to AFB1 results in several pathophysiological circumstances in a duration-dependent manner concerning neurodegeneration especially Alzheimer's disease.

Abstract
Eighty-four male New Zealand White rabbits with average body weight 778 ± 65 g were blocked into four groups to evaluate the ability of sodium bentonite and coumarin in alleviating the toxicity of aflatoxin B1. The first group was fed on a diet without any treatment (CON), while the remaining three diets were added with aflatoxin B1 at 0.25 ppm diet. Diet fed to the third and fourth group of rabbits were further supplemented with sodium bentonite at 5 g/kg (SOB) and coumarin at 5 g/kg (COU) of the diet, respectively. Feeding aflatoxin-contaminated diet (AFL) caused necrosis of liver tissue and reduced the weight gain, average daily gain, feed conversion ratio, nutrient digestibility coefficients, and nitrogen balance of rabbits. This, in turn, was reflected as a reduction in carcass characteristics. The serum collected from rabbits fed aflatoxin-contaminated diet showed decreased levels of total protein, albumin, globulin, glucose, total cholesterol, and triglycerides, and increased concentrations of urea, creatinine, and liver enzymes. Further, aflatoxin diet increased the cecal pH, and decreased the ammonia nitrogen, total volatile fatty acids, and individual fatty acids proportion of cecal fluid. Supplementing sodium bentonite and coumarin at 5 g/kg diet reduced the negative effects of aflatoxin B1 on growth performance, digestibility of nutrients, biochemical parameters, carcass characteristics, and cecal fermentation profile. Furthermore, the coumarin-supplemented group showed better body weight gains and carcass weights compared to the rabbits fed with diets containing sodium bentonite. In conclusion, both sodium bentonite and coumarin supplementation was beneficial in ameliorating the toxicity of aflatoxin B1. Further, the increased body weight gains and better-feed conversion in coumarin-supplemented rabbits project the coumarin as a better anti-aflatoxigenic supplement.

Abstract
Alternative and complimentary usage of the natural compound has raised hopes of finding curative options for liver hepatocarcinogenesis. In the present study, the curative effect of bee honey against diethylnitrosamine (DEN) (50 mg/kg) and carbon tetrachloride (CCl4) (2 mg/Kg)-induced hepatocellular carcinoma (HCC) in male rats in the presence or absence of some chemotherapeutic drugs, Cisplatin (Cis), Cyclophosphamide (CY) and 5- Fluorouracil (5-FU) were investigated. The obtained results demonstrated that treatment with DEN/CCl4 caused oxidative stress as assigned by the increase in malondialdehyde (MDA) and fall in glutathione (GSH) content. Meantime detraction in the antioxidants, including superoxide dismutase (SOD), catalase (CAT), glutathione-s-transferase (GST) and glutathione peroxidase (GPx) was observed. Also, the results showed induction of inflammation as reflected by an increase in the levels of both α- fetoprotein and α- fucosidase in the liver. This was accompanied by changes in the hepatic function biomarkers which characterized by the increased levels of transaminases (AST, ALT), alkaline phosphatase (ALP) and γ-Glutamyl transferase (γ-GT) and decrease in total protein content in the serum. In conclusion, the combination of the selected drugs and bee honey may be an effective chemo- preventive and therapeutic strategy for treating DEN and CCl4-induced HCC.

Abstract
The metabolism of aflatoxin B1 (AFB1) generates reactive oxygen
species (ROS) that destroys hepatocytes. Meanwhile, astaxanthin (AX) is known to have
stronger antioxidative activity than other carotenoids. This study aimed to investigate
hepatoprotective role of AX from AFB1-induced toxicity in rat by
histopathological study and immunohistochemistry of Cu/Zn-SOD (SOD1) which acts as the
first enzyme in antioxidative reaction against cell injury from ROS. Twenty Wistar rats
were randomly divided into 4 groups. The control and AFB1 groups were gavaged
by water for 7 days followed by a single DMSO and 1 mg/kg AFB1, respectively.
The AXL+ AFB1 and AXH+ AFB1 groups were given of 5 mg/kg and 100
mg/kg AX for 7 days before 1 mg/kg AFB1 administration. The result showed
significantly elevated liver weight per 100 g body weight in AFB1 group. The
histopathological finding revealed vacuolar degeneration, necrosis, megalocytosis and
binucleation of hepatocytes with bile duct hyperplasia in AFB1 group. The
severities of pathological changes were sequentially reduced in AXL+AFB1 and
AXH+AFB1 groups. Most rats in AXH+AFB1 group owned hypertrophic
hepatocytes and atypical proliferation of cholangiocytes which are adaptive responses to
severe hepatocyte damage. The SOD1 expression was also significantly higher in
AXH+AFB1 group than solely treated AFB1 and AXL+AFB1
groups. In conclusion, AX alleviated AFB1-induced liver damage in rat by
stimulating SOD1 expression and transdifferentiation of cholangiocytes in dose dependent
manner.

Abstract
Oxidative stress is an important molecular mechanism for kidney injury in aflatoxin B1 (AFB1) nephrotoxicity. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a master transcription factor for regulating the cellular oxidative stress response, which has been confirmed in animal models. Lycopene (LYC), a natural carotenoid, has received extensive attention due to its antioxidant effect with the activation of Nrf2. However, the role of LYC in protecting against AFB1-induced renal injury is unknown. To evaluate the chemoprotective effect of LYC on AFB1-induced renal injury, forty-eight male mice were randomly divided into 4 groups and treated with LYC (5 mg per kg of bodyweight) and/or AFB1 (0.75 mg per kg of bodyweight) by intragastric administration for 30 days. AFB1 and LYC were respectively dissolved in olive oil. We found that AFB1 exposure significantly increased the serum concentrations of blood urea nitrogen (BUN) and serum creatinine (SCR), and caused damage to the renal structure. Notably, LYC potentially alleviated AFB1-induced kidney lesions through attenuating AFB1-induced oxidative stress. Renal nuclear factor-erythroid 2-related factor 2 (Nrf2) and its downstream target gene (CAT, NQO1, SOD1, GSS, GCLM and GCLC) translation and protein expression were ameliorated by pretreatment with LYC in AFB1-exposed mice. These results suggested that LYC potentially alleviates AFB1-induced renal injury. This effect may be attributed to the enhancement of renal antioxidant capacity with the activation of the Nrf2 antioxidant signaling pathway.

Abstract
No consensus exists with respect to positive hepatitis B virus (HBV) DNA results and persistent normal or mildly elevated alanine aminotransferase (ALT). The aim of this study is to investigate the appropriate management and prognosis of these populations with chronic hepatitis B (CHB). A total of 235 subjects with positive HBV DNA results and persistent normal or mildly elevated ALT were enrolled in this study. Liver biopsy and liver stiffness measurements (LSM) were performed in all participants at baseline. Antiviral therapy was initiated in patients with significant hepatic inflammation (G ≥ 2) and/or fibrosis (S ≥ 2). The patients were divided into entecavir and adefovir groups based on HBV DNA load (>2000 IU/mL vs <2000 IU/mL). The liver biopsies were repeated at 72 weeks for the patients received antiviral therapy. We found that 112 subjects were hepatitis B e antigen (HBeAg) positive, and 123 subjects were negative. The corresponding median ALTs were 46 (39.5-52.5) and 48 (41.5-57.0) U/mL, respectively. G ≥ 2 and/or S ≥ 2 diseases were present in 48.8% (82/168) of the HBeAg-positive and 51.2% (86/168) of HBeAg-negative patients, respectively. In addition, 96 HBeAg-positive and 72 HBeAg-negative patients were divided into entecavir and adefovir groups. Meanwhile, liver biopsies had greater diagnostic accuracy for determining cirrhosis than LSM (0.711 vs 1.0, P < 0.0001). At the end of the study period, undetectable HBV DNA levels and normal ALT levels were observed in CHB-infected patients. Furthermore, the patients showed histologic improvement at 72 weeks compared with baseline measurements (G, 1.72 ± 1.00 vs 0.73 ± 0.88, P = 0.0002; S, 1.484 ± 0.90 vs 0.99 ± 1.13, P < 0.0001). Collectively, liver biopsy enhanced diagnostic accuracy for CHB-infected individuals with persistent normal or mildly elevated aminotransferase levels. Moreover, antiviral therapy can improve or regress the hepatic fibrosis and cirrhosis.

Abstract
Various diseases are known to be associated with an imbalance of the redox state, but in vivo detection of free radicals is difficult. The purpose of this study is to establish a method for in vivo visualization of redox status by high-resolution whole-body MRI using nitroxide radicals. A redox-sensitive nitroxide probe, 3-carbamoyl-2,2,5,5-tetramethylpyrrolidine-1-oxyl (carbamoyl-PROXYL), was administered to rats intravenously, and in vivo T1-weighted MRI was performed to virtually visualize the redox status of various organs. In experiments using phantoms, a linear relationship between the MRI signal and the carbamoyl-PROXYL concentration persisted up to 80 mM. Among the phantoms, a sample containing 1 mM carbamoyl-PROXYL was readily identifiable. After intravenous injection of carbamoyl-PROXYL, whole-body T1-weighted MRI of the rat provided clear images with good spatial and temporal resolution. The signal intensities of four selected organs (heart, liver, kidney, and intestine) were analyzed quantitatively. The carbamoyl-PROXYL signal peaked and gradually declined due to reduction after intravenous injection. Among the four organs, the organ-specific reduction rate of carbamoyl-PROXYL was highest in the heart, followed by (in order) the liver, kidney, and intestine, and statistical analysis showed that the inter-organ differences were significant. In conclusion, T1-weighted carbamoyl-PROXYL-enhanced MRI provides excellent spatial and temporal imaging of carbamoyl-PROXYL distribution. Furthermore, it provides important functional information pertaining to blood flow and tissue redox activity in individual organs. MRI in combination with carbamoyl-PROXYL has potential clinical application for evaluation of redox activity in whole organs.

Abstract
BACKGROUND Obstructive jaundice is a serious, life-threatening condition that can lead to death as a result of sepsis and multiorgan failure due to bacterial translocation. Treatment should be started as soon as possible after diagnosis. MATERIAL AND METHODS Forty 24-week-old male Sprague Dawley rats, with an average weight of 250 g to 300 g, were included in this study. The rats were randomly placed into five groups, each group consisted of eight rats. The sham group underwent only common bile duct (CBD) dissection and no ligation was performed. CBD ligation was applied to the other groups. After the operation, one CBD group was fed with rat chow only, the others were fed with rat chow supplemented with honey, or immunonutrients, or honey plus immunonutrients. After 10 to 12 days, all rats were sacrificed; blood and tissue samples were collected for biochemical, microbiological, and histopathological evaluation. RESULTS In the groups that were fed with honey and immunonutrients, alanine aminotransferase (ALT) levels were decreased significantly compared to the other groups. Statistically significant differences were detected in terms of bacterial translocation (BT) rates among liver and spleen samples, and laboratory values of serum, except for MLNs of the BDL+HI group, when compared to other groups. We found mean mucosal thickness of ileum samples have been improved notably in the BDL+HI group compared to the other groups, especially compared to the C/BDL group. CONCLUSIONS Immunonutrition applied with honey had immunostimulant effects, decreased BT due to an additive effect, and had positive effects on intestinal mucosa.

Abstract
This study was conducted to investigate the effect of dietary supplementation of Aspergillus awamori on aflatoxin B1 (AFB1)-induced liver damage in rabbits. Administration of AFB1 (0.3 mg/kg diet) led to a significant reduction in body weight, body weight gain, total feed intake, total serum proteins, albumin, high density lipoprotein-cholesterol, phagocytic activity, phagocytic index, and the antioxidant enzyme, glutathione peroxidase (GPx). Moreover, AFB1 administration was associated with a significant increase in feed conversion ratio, lipid peroxidation and serum levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, lactate dehydrogenase and total bilirubin. In addition, livers of AFB1-supplemented animals showed fatty degeneration with vacuolisation, focal areas of necrosis, mononuclear cells infiltration hyperplasia of bile ducts and sinusoids. A significant increase in the hepatic expression of the biotransformation gene (Cyp3A6), stress-sensitive genes (HO1 and SOD1), and inflammation-related genes (IL6, TNFa, NF-kB, and Cox2) was also observed. Supplementation of the diets with 0.05, 0.1 or 0.15% A. awamori ameliorated all AFB1 deleterious effects with the best improvement observed at the lowest concentration. This is the first investigation to report that supplementation of rabbit diets with A. awamori has an ameliorative effect against AFB1-induced liver damage possibly through preventing hepatic oxidative stress, promoting the antioxidant defence systems, and inhibiting expression of Cyp3A6, HO1, SOD1, IL6, TNFa, NF-kB, and Cox2. Therefore, A. awamori could be used as a potential preventive or therapeutic agent for aflatoxicosis.
