The ultrastructural research of liver in experimental obstructive jaundice and effect of honey

Al-Hijamah (Prophetic Wet Cupping Therapy) is a Novel Adjuvant Treatment for Viral Hepatitis That Excretes Viral Particles and Excess Ferritin Percutaneously, Synergizes Pharmacotherapy, Enhances Antiviral Immunity and Helps Better HCC Prevention and Treatment: A Novel Evidence-Based Combination with Prophetic Medicine Remedies

Viral hepatitis progresses to liver cirrhosis and HCC. Several challenges are facing Sovaldi treatment to viral C hepatitis, eg, viral resistance, difficulty to treat all genotypes, and inability to access treatments in low-income countries. Also, current treatments to Hepatitis B are still challenging. Ideal treatments to viral hepatitis should decrease the viral load, enhance antiviral immunity and repair the viruses-induced tissue damage. That is still beyond reach. High serum ferritin in viral hepatitis correlates with chronicity, increased necro-inflammation, hepatotoxicity, progression to cirrhosis, progression to HCC, unresponsiveness to treatments and viremia. Previously, Al-hijamah (wet cupping therapy of prophetic medicine) significantly cleared thalassemic children of causative pathological substances (CPS), eg, excess ferritin, free radicals and serum lipids. Moreover, Al-hijamah significantly increased the antioxidant power and potentiated the natural antiviral immunity, eg, increasing CD4 count, CD8 count and CD4/CD8 ratio. Prophet Muhammad peace be upon him said: "If there is a benenvolence (benefit) in any of your medicines, benefit will be in shrtat mihjam (Al-hijamah), honey drink, and a stinge of fire compatible with disease and I do not like to cauterize". Likewise, the author suggests Al-hijamah as a novel promising adjuvant treatment for viral hepatitis (B and C) for percutaneous excretion of CPS as hepatitis viral particles, excess ferritin, inflammatory mediators, free radicals, and antigen-antibody complexes. Published reports proved that Al-hijamah exerted tissue-protective effects, and cleared blood through the fenestrated skin capillaries in a pressure-dependent and size-dependent manner (a kidney-like manner). That collectively may decrease the viral load for better HCC prevention and supports the evidence-based Taibah theory (Taibah mechanism). Same therapeutic benefits apply to other viral illnesses as AIDS. Even after HCC development, Al-hijamah is quite mandatory for excretion and clearance of CPS that favor malignancy, eg, lactate (Warburg effect), growth factors, metalloproteinases, and others. Al-hijamah-induced immune potentiation benefits HCC patients. Combining Al-hijamah with other natural antioxidant remedies of prophetic medicine, eg, nigella sativa, costus, natural honey, Zamzam water and others will maximize the therapeutic benefits. In conclusion, Al-hijamah and other prophetic medicine remedies are recommended adjuvants to current pharmacological treatments to viral hepatitis and HCC.

The effect of Ankaferd blood stopper on liver damage in experimental obstructive jaundice

Background/aims

To evaluate the potential protective effects of Ankaferd blood stopper (ABS) in an experimental obstructive jaundice (OJ) model.

Materials and methods

The study included 26 female rats, which were divided into 3 groups. The sham group, consisting of 10 rats, (group 1) only received solely laparotomy. In the control group, consisting of 8 rats, (group 2), ligation was applied to the biliary tract and no treatment was implemented. In the treatment group, consisting of 8 rats, (group 3), following ligation of biliary tract, 0.5 mL/day ABS was given for 10 days. Liver tissue and blood samples were taken for histopathological and biochemical examination.

Results

Compared to group 2, group 3 had higher aspartate aminotransferase (AST), total oxidant status (TOS) malondialdehyde (MDA), fluorescent oxidant products (FOP), and lower expression of albumin and total antioxidant status (TAS) (P < 0.05). In histopathological analysis, the mean scores of all histopathological parameters (fibrosis, portal inflammation, confluent necrosis, interphase activity, bile duct proliferation) have statistical significance between group 2 and group 3 (P < 005).

Conclusions

ABS has promising results in the treatment of experimental OJ because of its antioxidant and antiinflammatory properties. It may be used in clinical practice after more extensive studies about the effects of ABS on OJ.

Hepatoprotective Effects of a Novel Trihoney against Nonalcoholic Fatty Liver Disease: A Comparative Study with Atorvastatin

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.

Honey and obesity-related dysfunctions: a summary on health benefits

Honey is a natural product, containing flavonoids and phenolic acids, appreciated for its therapeutic abilities since ancient times. Although the bioactive potential is linked to the composition, that is variable depending on mainly the botanical origin, honey has antioxidant and anti-inflammatory properties. Therefore, honey, administered alone or in combination with conventional therapy, might result useful in the management of chronic diseases that are commonly associated with oxidative stress and inflammation state. Obesity is a metabolic disorder characterized by visceral adiposity. The adipose tissue becomes hypertrophic and undergoes hyperplasia, resulting in a hypoxic environment, oxidative stress and production of pro-inflammatory mediators that can be responsible for other disorders, such as metabolic syndrome and neurodegeneration. Experimental evidence from animals have shown that honey improves glycemic control and lipid profile with consequent protection from endothelial dysfunction and neurodegeneration. The purpose of the present review is to summarize the current literature concerning the beneficial effects of honey in the management of the obesity-related dysfunctions, including neurodegeneration. Based on the key constituents of honey, the paper also highlights polyphenols to be potentially responsible for the health benefits of honey. Further well-designed and controlled studies are necessary to validate these benefits in humans.

Combined Effectiveness of Honey and Immunonutrition on Bacterial Translocation Secondary to Obstructive Jaundice in Rats: Experimental Study

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.

The Effect of Calcium Dobesilate on Liver Damage in Experimental Obstructive Jaundice

Purpose/Aim of the study: Inflammation and oxidative stress are two significant factors affecting the degree of liver damage in obstructive jaundice. The aim of this study was to evaluate the effect of calcium dobesilate (CaDob), an effective antioxidant and anti-inflammatory drug, on damage to liver caused by experimental obstructive jaundice.

MATERIALS AND METHODS

30 rats in total were randomly placed into three groups, each group consisting of 10 rats. The sham group (Group 1) only received solely laparotomy. In the control group (Group 2), ligation was applied to the biliary tract and no treatment was implemented. In the CaDob group (Group 3), following ligation of the biliary tract, 100 mg/kg/day CaDob was implemented via an orogastric tube for a 10-day period. Liver tissue and blood samples were taken for histopathological and biochemical examination.

RESULTS

The CaDob group had significantly lower test values for serum liver functions when compared to the control group. Statistically lower levels of tissue malondialdehyde (MDA) and fluorescent oxidation products (FOP) were detected in the CaDob group, and the CaDob group had significantly higher levels of sulfydryl (SH) than the control group. Histopathological scores in the CaDob group were found out to be statistically less than the scores the control group received (p < 0.05).

CONCLUSIONS

CaDob treatment repaired the histpatological changes induced by bile duct ligation. The hepatoprotective effects of CaDob can be associated with its antioxidant properties of the drug.

Novel Insights into the Health Importance of Natural Honey

Honey is a sweet, flavourful liquid substance with several beneficial constituents. Extensive research has shown the therapeutic promise of the use of honey in enhancing health values and improving body systems. This manuscript documents the ancient medicinal uses of honey and provides evidence-based data demonstrating its benefits in animal models, patients, and healthy individuals. Several reports by various researchers are discussed regarding health indices and biomarkers used following apitherapy. These include physiological processes in virtually all animal and human organs. The responses of body systems after oral and systemic administration of honey are also mentioned. Honey is also evaluated for its wide acceptability as a complementary and alternative medicine for most ailments. All types of honey exhibit different biochemical activities and show greater variability in their potency as apitherapeutic agents than conventional medicines. The mechanisms of action conferring honey's protective effects, as suggested by various authors, are documented. These entail synergistic interaction of the bioactive physical and chemical constituents of honey to produce the desired beneficial effects. The use of apitherapy in synergy with chemotherapy to manage microbial and cancer ailments is also helpful in reducing drug-induced cytotoxicity. The mechanistic insights into the overall protective, preventive, and therapeutic effects of honey portend the presence of a unique factor, a 'synergistic multiple ingredients factor', designated SMIF.

The Effect of Montelukast on Liver Damage in an Experimental Obstructive Jaundice Model

Background

Montelukast is a cysteinyl-leukotriene type 1 (CysLT₁) selective receptor antagonist. In recent years, investigations have shown that montelukast possesses secondary anti-inflammatory activities and also antioxidant effects. For this reason, we aimed to determine the possible effects of montelukast on liver damage in experimental obstructive jaundice.

Methods

30 Wistar-Albino male rats were randomized and divided into three groups of 10 animals each: group I, sham-operated; group II, ligation and division of the common bile duct (BDL) followed by daily intraperitoneal injection of 1 ml of saline; group III, BDL followed by daily intraperitoneal injection of 10 mg/kg montelukast dissolved in saline. The animals were killed on postoperative day 7 by high-dose diethyl ether inhalation. Blood and liver samples were taken for examination.

Results

In this study, liver malondialdehyde (MDA) (p = 0.001), myeloperoxidase (p = 0.003), and total sulfhydryl (SH) (p = 0.009) were found to be significantly different between the BDL + montelukast and the BDL groups. Plasma total SH (p = 0.002) and MDA (p = 0.027) values were also statistically different between these groups. Statistical analyses of histological activity index scores showed that the histopathological damage in the BDL + montelukast group was significantly less than the damage in the control group (p < 0.05 for all pathological parameters).

Conclusion

According to the results of this study, montelukast showed a significant hepatoprotective effect in this experimental obstructive jaundice model, which might be due to its antioxidant and anti-inflammatory activities.

Attenuation of CCl4-Induced Oxidative Stress and Hepatonephrotoxicity by Saudi Sidr Honey in Rats

The present study was undertaken to investigate the possible protective effect of Saudi Sidr honey (SSH) on carbon tetrachloride (CCl4) induced oxidative stress and liver and kidney damage in rat. Moreover, the antioxidant activity and the phenolic and flavonoidal contents were determined. The hepatorenal protective activity of the SSH was determined by assessing biochemical, hematological, and histological parameters. Serum transaminases, ALP, GGT, creatinine, bilirubin urea, uric acid, and MDA level in liver and kidney tissues were significantly elevated, and the antioxidant status of nonprotein sulfhydryls, albumin, and total protein levels in liver and kidney were declined significantly in CCl4 alone treated animals. Pretreatment with SSH and silymarin prior to the administration of CCl4 significantly prevented the increase of the serum levels of enzyme markers and reduced oxidative stress. SSH also exhibited a significant lipid-lowering effect and caused an HDL-C enhanced level in serum. The histopathological evaluation of the liver and kidney also revealed that honey protected incidence of both liver and kidney lesions. Moreover, SSH showed a strong antioxidant activity in DPPH and β -carotene-linoleic acid assays. SSH was found to contain phenolic compounds. Additionally, the SSH supplementation restored the hepatocytes viability against 2',7'-dichlorofluorescein (DCF) toxicity in ex vivo test.

Honey--a novel antidiabetic agent

Diabetes mellitus remains a burden worldwide in spite of the availability of numerous antidiabetic drugs. Honey is a natural substance produced by bees from nectar. Several evidence-based health benefits have been ascribed to honey in the recent years. In this review article, we highlight findings which demonstrate the beneficial or potential effects of honey in the gastrointestinal tract (GIT), on the gut microbiota, in the liver, in the pancreas and how these effects could improve glycemic control and metabolic derangements. In healthy subjects or patients with impaired glucose tolerance or diabetes mellitus, various studies revealed that honey reduced blood glucose or was more tolerable than most common sugars or sweeteners. Pre-clinical studies provided more convincing evidence in support of honey as a potential antidiabetic agent than clinical studies did. The not-too-impressive clinical data could mainly be attributed to poor study designs or due to the fact that the clinical studies were preliminary. Based on the key constituents of honey, the possible mechanisms of action of antidiabetic effect of honey are proposed. The paper also highlights the potential impacts and future perspectives on the use of honey as an antidiabetic agent. It makes recommendations for further clinical studies on the potential antidiabetic effect of honey. This review provides insight on the potential use of honey, especially as a complementary agent, in the management of diabetes mellitus. Hence, it is very important to have well-designed, randomized controlled clinical trials that investigate the reproducibility (or otherwise) of these experimental data in diabetic human subjects.

Honey: a novel antioxidant

The global prevalence of chronic diseases such as diabetes mellitus, hypertension, atherosclerosis, cancer and Alzheimer's disease is on the rise. These diseases, which constitute the major causes of death globally, are associated with oxidative stress. Oxidative stress is defined as an "imbalance between oxidants and antioxidants in favor of the oxidants, potentially leading to damage". Individuals with chronic diseases are more susceptible to oxidative stress and damage because they have elevated levels of oxidants and/or reduced antioxidants. This, therefore, necessitates supplementation with antioxidants so as to delay, prevent or remove oxidative damage. Honey is a natural substance with many medicinal effects such as antibacterial, hepatoprotective, hypoglycemic, reproductive, antihypertensive and antioxidant effects. This review presents findings that indicate honey may ameliorate oxidative stress in the gastrointestinal tract (GIT), liver, pancreas, kidney, reproductive organs and plasma/serum. Besides, the review highlights data that demonstrate the synergistic antioxidant effect of honey and antidiabetic drugs in the pancreas, kidney and serum of diabetic rats. These data suggest that honey, administered alone or in combination with conventional therapy, might be a novel antioxidant in the management of chronic diseases commonly associated with oxidative stress. In view of the fact that the majority of these data emanate from animal studies, there is an urgent need to investigate this antioxidant effect of honey in human subjects with chronic or degenerative diseases.

Splanchnic Th(2) and Th(1) cytokine redistribution in microsurgical cholestatic rats

BACKGROUND

Long-term extrahepatic cholestasis in the rat induces ductular proliferation and fibrosis in the liver, portal hypertension, splenomegaly, portosystemic collateral circulation, and ascites. These splanchnic alterations could have an inflammatory pathophysiology.

MATERIAL AND METHODS

We measured serum levels of hepatobiliary injury markers and the acute phase proteins, alpha-1-major acid protein (alpha(1)-MAP) and alpha-1-acid glycoprotein (alpha(1)-GPA) in rats 6 wk after microsurgical extrahepatic cholestasis. We also assayed Th(1) (TNF-alpha and IL-1beta) and Th(2) (IL-4 and IL-10) cytokine levels in the liver, ileum, spleen, and mesenteric lymph complex by enzyme-linked immunosorbent assay (ELISA) techniques. Liver fibrosis was measured by Sirius red stain and by using an image system computer-assisted method and mast cell liver infiltration by Giemsa stain.

RESULTS

The cholestatic rats showed an increase (P<0.001) in serum levels of bile acids, total and direct bilirubin, AST, ALT, AST/ALT index, gamma-GT, alkaline phosphatase, alpha(1)- MAP, alpha(1)-GPA, and LDH (P<0.05) in relation to sham-operated rats. TNF-alpha, IL-1beta, IL-4, and IL-10 increased in the ileum (P<0.01) and mesenteric lymph complex (P<0.001), and decreased in the liver (P<0.001). A marked bile proliferation associated with fibrosis (P<0.001) and mast cell infiltration was also shown in the liver of cholestatic rats.

CONCLUSION

The splanchnic redistribution of cytokines, with an increase of Th(1) and Th(2) production in the small bowel and in the mesenteric lymph complex, supports the key role of inflammatory mechanisms in rats with secondary biliary fibrosis.

Effect of salvia miltiorrhizae on the expressions of TLR4 protein in the liver of rats with SAP or OJ

To investigate the effect of salvia miltiorrhizae on the expressions of TLR4 protein in the liver of rats with severe acute pancreatitis (SAP) and obstructive jaundice (OJ), and explore the protective mechanism of salvia miltiorrhizae on the liver of rats. A total of 288 mice was used in SAP- (n = 108) and OJ-associated experiments (n = 180). The rats were randomly divided into sham-operated, model control and treated group. Based on the different time points after operation, these groups were subdivided into 3, 6 and 12 h subgroups (SAP rats, n = 12) or 7, 14, 21 and 28 days subgroups (OJ rats, n = 15). At the corresponding time points after operation, blood and liver specimens were collected to determine the contents of endotoxin and TNF-alpha in the blood as well as the expression levels of TLR4 protein in the liver. Compared with the corresponding model control group, though the number of dead SAP or OJ rats in the treated group declined, no statistical difference was noted; The levels of plasma endotoxin in SAP (at 6 and 12 h) or OJ rats in the treated group decreased significantly (P < 0.001 and P < 0.01, respectively); The levels of serum TNF-alpha in SAP (at 12 h) or OJ rats (on 14 days) declined (P < 0.001 and P < 0.01, respectively); The staining intensity as well as the product of staining intensity and positive rate of TRL4 protein only significantly declined on 7 and 28 days in OJ rats (P < 0.01). On 7 days, treated group in positive rate of TLR4 protein were significantly lower than that in model control group (P < 0.01). The pathological changes in different treated groups of SAP and OJ rats were improved. Salvia miltiorrhizae is able to reduce the levels of plasma endotoxin and inhibit effectively the expressions of TLR4 protein in the liver of SAP or OJ rats, thereby decreasing inflammatory reaction and exerting protective effect on liver function.

Advances in hepatic barrier function and injury

Hepatic barrier is a very important structure to protect hepar, and also considerable to protect liver's function. It can prevent endotoxin and virus from entering hepar to damage hepatocyte. The primary aim of this review is to introduce the research status of hepatic barrier and analyze its function and structure. We also introduce several kinds of factors that can induce the failure of the barrier's structure and function and some countermeasures that can resist this factors.

Experimental obstructive cholestasis: the wound-like inflammatory liver response

Obstructive cholestasis causes hepatic cirrhosis and portal hypertension. The pathophysiological mechanisms involved in the development of liver disease are multiple and linked. We propose grouping these mechanisms according to the three phenotypes mainly expressed in the interstitial space in order to integrate them.Experimental extrahepatic cholestasis is the model most frequently used to study obstructive cholestasis. The early liver interstitial alterations described in these experimental models would produce an ischemia/reperfusion phenotype with oxidative and nitrosative stress. Then, the hyperexpression of a leukocytic phenotype, in which Kupffer cells and neutrophils participate, would induce enzymatic stress. And finally, an angiogenic phenotype, responsible for peribiliary plexus development with sinusoidal arterialization, occurs. In addition, an intense cholangiocyte proliferation, which acquires neuroendocrine abilities, stands out. This histopathological finding is also associated with fibrosis.It is proposed that the sequence of these inflammatory phenotypes, perhaps with a trophic meaning, ultimately produces a benign tumoral biliary process - although it poses severe hepatocytic insufficiency. Moreover, the persistence of this benign tumor disease would induce a higher degree of dedifferentiation and autonomy and, therefore, its malign degeneration.

Ultrastructural view of colon anastomosis under propolis effect by transmission electron microscopy

AIM: To evaluate the effect of propolis administration on the healing of colon anastomosis with light and transmission electron microscopes.

METHODS: Forty-eight Wistar-Albino female rats were divided into two groups and had colon resection and anastomosis. In group I, rats were fed with standard rat chow pre- and postoperatively. The rats in group II were fed with standard rat chow and began receiving oral supplementation of propolis 100 mg/kg per day beginning 7 d before the operation and continued until they were sacrificed. Rats were sacrificed 1, 3, 7 and 14 d after operation, and anastomotic bursting pressures measured. After the resection of anastomotic segments, histopathological examination was performed with light and transmission electron microscopes by two blinded histologists and photographed.

RESULTS: The colonic bursting pressures of the propolis group were statistically significantly better than the control group. Ultrastructural histopathological analysis of the colon anastomosis revealed that propolis accelerated the phases of the healing process and stimulated mature granulation tissue formation and collagen synthesis of fibroblasts.

CONCLUSION: Bursting pressure measurements and ultra structural histopathological evaluation showed that administration of propolis accelerated the healing of colon anastomosis following surgical excision.
