Litchi pulp-derived gamma-aminobutyric acid (GABA) extract counteracts liver inflammation induced by litchi thaumatin-like protein.

Gamma-aminobutyric acid (GABA) is the predominant amino acid in litchi pulp, known for its neuroregulatory effects and anti-inflammatory properties. Although previous research has highlighted the pro-inflammatory characteristics of litchi thaumatin-like protein (LcTLP), interplay between GABA and LcTLP in relation to inflammation remains unclear. This study aims to explore the hepatoprotective effects of the litchi pulp-derived GABA extract (LGE) against LcTLP-induced liver inflammation in mice and LO2 cells. In vivo experiments demonstrated that LGE significantly reduced the levels of aspartate transaminase and alanine transaminase, and protected the liver against infiltration of CD4+ and CD8+ T cells and histological injury induced by LcTLP. Pro-inflammatory cytokines including interleukin-6, interleukin-1ß, and tumor necrosis factor-α were also diminished by LGE. The LGE appeared to modulate the mitogen-activated protein kinase (MAPK) signaling pathway to exert its anti-inflammatory effects, as evidenced by a reduction of 47%, 35%, and 31% in phosphorylated p38, JNK, and ERK expressions, respectively, in the liver of the high-dose LGE group. Additionally, LGE effectively improved the translocation of gut microbiota by modulating its microbiological composition and abundance. In vitro studies have shown that LGE effectively counteracts the increase in reactive oxygen species, calcium ions, and pro-inflammatory cytokines induced by LcTLP. These findings may offer new perspectives on the health benefits and safety of litchi consumption.

Hepatoprotective effects of leaf extract of Annona senegalensis against aflatoxin B1 toxicity in rats.

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.

Ameliorative effect of bofutsushosan (Fangfengtongshengsan) extract on the progression of aging-induced obesity.

This study aimed to compare fat accumulation in young and aged mice raised on a high-fat diet and to characterize the obesity-reducing effects of a Kampo medicine, bofutsushosan (BTS; fangfengtongshengsan in Chinese). Aged mice fed a high-fat diet containing 2% BTS extract for 28 days exhibited a significant reduction in weight gain and accumulation of visceral and subcutaneous fat, which were greater degree of reduction than those of the young mice. When the treatment period was extended to two months, the serum aspartate aminotransferase and alanine aminotransferase levels and the accumulation of fat droplets in the hepatocytes decreased. The mRNA expression of mitochondrial uncoupling protein 1 (UCP1) in the brown adipose tissue was significantly reduced in the aged mice compared to the young mice but increased by 2% in the BTS-treated aged mice. Additionally, the effect of BTS extract on oleic acid-albumin-induced triglyceride accumulation in hepatoblastoma-derived HepG2 cells was significantly inhibited in a concentration-dependent manner. Evaluation of the single crude drug extracts revealed that Forsythia Fruit, Schizonepeta Spike, and Rhubarb were the active components in BTS extract. These results suggest that BTS extract is effective against visceral, subcutaneous, and ectopic fats in the liver, which tend to accumulate with aging. Thus, BTS extract is useful in preventing and ameliorating the development of obesity and metabolic syndrome.

The hepatoprotective potentials of Olea europaea L. leaves against carbon tetrachloride-induced hepatic injury in rats.

OBJECTIVE: To examine the therapeutic effects of Olea europaea L. leaves extract on carbon tetrachloride-induced liver injury in rats. Methods: The experimental study was conducted at the Department of Physiology, University of Karachi, Karachi, in July 2021, and comprised Albino Wistar male rats weighing 180-220gm. The animals were divided into control group I, carbon tetrachloride group II, Olea europaea L. + carbon tetrachloride group III and Olea europaea L. group IV. In Vitro model of hepatic toxicity was developed by carbon tetrachloride. A daily dose of 50mg/kg of aqueous extract of olive leaves was administered orally and 0.8ml/kg of carbon tetrachloride was administered twice a week subcutaneously for 28 days. On the 29th day, the animals were sacrificed, and tested for hepatic enzymes, lipid peroxidation markers and histopathology. Data was analysed using SPSS 20. RESULTS: Of the 24 rats, 6(25%) were in each of the 4 groups. Alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and total bilirubin levels were significantly reduced (p<0.05) in group II whereas, 4- hydroxynonenal, isoprostane and malondialdehyde levels were significantly increased (p<0.05). However, total antioxidant level increased significantly (p<0.05) in group III compared to group II. Histopathology showed severe liver damage in group II and mild damage in group III. Conclusion: Olea europaea L. leaves extract was found to have profound hepatoprotective effects.

Protective Mechanisms of Juncus effusus and Carbonized Juncus effusus against D-Galactosamine-Induced Acute Liver Injury in Mice.

This study investigated the hepatoprotective effects of Juncus effusus (J. effusus) and Carbonized J. effusus against liver injury caused by D-galactosamine (D-GalN) in mice. J. effusus and Carbonized J. effusus were administered by gavage once daily starting seven days before the D-GalN treatment. The results of the study indicated that J. effusus and Carbonized J. effusus suppressed the D-GalN-induced generation of serum alanine transaminase (ALT), aspartate aminotransferase (AST), hepatic malondialdehyde (MDA) and tumor necrosis factor-alpha (TNF-α) was observed. The values of superoxide dismutase (SOD) exhibited an increase. In addition, J. effusus and Carbonized J. effusus promoted the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2), NADPH quinone oxidoreductase-1 (NQO-1), heme oxygenase-1 (HO-1) as well as the mRNA expression of Nrf2, HO-1, NQO-1 and Glutamate cysteine ligase catalytic subunit (GCLC). The compressed Carbonized J. effusus demonstrated the optimum impact. These results suggest that J. effusus and Carbonized J. effusus protect against D-GalN-induced acute liver injury through the activation of the Nrf2 pathway.

Analyzing the Correlation Between Serum Biomarkers and Child-Pugh Score in Liver Cirrhosis.

Objective: This study aimed to analyze the diagnostic efficacy of serum biomarkers in liver cirrhosis patients categorized by Child-Pugh scores. Methods: An observational cross-sectional study design was employed. A total of 110 liver cirrhosis patients, classified according to Child-Pugh scores and 60 healthy individuals were included in this study. Serum levels of adenosine deaminase (ADA), adiponectin (APN), matrix metalloproteinase-2 (MMP-2), alkaline phosphatase (ALP), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured. Results: The levels of ADA, APN, MMP-2, ALP, ALT, and AST were significantly higher in the study group compared to the control group (P < .05). Furthermore, these levels increased with the severity of liver cirrhosis, with higher levels observed in patients with Child-Pugh class C. The positive diagnostic rates for joint detection in Child-Pugh class A, B, and C were 93.75% (30/32), 100% (34/34), and 100% (44/44), respectively. Conclusions: Combined detection of serum biomarkers improves the diagnostic efficacy of liver cirrhosis. The diagnostic rates were higher when considering Child-Pugh scores, with the highest rates observed in class C.

Citrus limon (L.) Osbeck Fruit Peel Extract Attenuates Carbon Tetrachloride-Induced Hepatocarcinogenesis in Sprague-Dawley Rats.

Background: Traditional herbal medicine practitioners in the Ashanti region of Ghana use the fruit peels of Citrus limon (L.) Osbeck (C. limon) in preventive and curative treatment of many cancers including liver cancer. This ethnobotanical claim remains to be verified scientifically. Aim of the Study. This study investigated prophylactic hepatoprotective and anti-HCC effects of C. limon peel extract (LPE) in CCl4/olive oil-induced HCC-like rats. Materials and Methods: After preparation of LPE, it was subjected to phytochemical screening using standard phytochemical methods. A total of 30 healthy adult male Sprague-Dawley rats (weighing 150-200 g) were randomly assigned into six groups of 5 rats each. Rats in the control group received olive oil (5 mL/kg ip) twice weekly for 16 weeks. Rats in the model group received CCl4/olive oil (2 mL/kg, ip) twice weekly for 16 weeks. Rats in capecitabine (10 mg/kg po) and LPE (50, 100, and 200 mg/kg po) groups received CCl4/olive oil (2 mL/kg, i.p) in the morning and their respective treatments in the afternoon twice a week for 16 weeks. Rats in all groups had free access to food and water ad libitum. Body weight and survival rates were monitored. Rats were sacrificed under deep anesthesia, blood was collected, and liver and other organs were isolated. Aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), prothrombin time, bilirubin, C-reactive protein (CRP), alpha- (α-) fetoprotein (AFP), and liver histology were assessed. Results: Alkaloids, tannins, flavonoids, terpenoids, and saponins were detected in LPE. Model rats demonstrated increased serum levels of AFP, CRP, ALP, GGT, ALT, and AST, prothrombin time, total bilirubin, direct bilirubin, blood lymphocyte, and monocyte counts, but decreased serum albumin and total protein compared to control rats. Unlike the control, model rats demonstrated fat accumulation in periportal and centrilobular hepatocytes and neoplastic transformation. Semiquantitation of periodic acid Schiff- (PAS-) stained liver sections showed decreased glycogen storage in hepatocytes of model rats compared to control rats. Compared to the model, LPE treatment protected against CCl4-induced hepatocarcinogenesis, which was evidenced by decreased AFP, CRP, liver enzymes, total and direct bilirubin, prothrombin time, and blood lymphocyte and monocyte counts; attenuation of fat accumulation; and increased glycogen storage, albumin, and total protein. Conclusion: LPE abates CCl4-induced hepatocarcinogenesis by attenuating liver inflammation and improving metabolic, biosynthetic, and detoxification functions of the liver. The prophylactic hepatoprotective and anti-hepatocarcinogenic effects of LPE are attributable to its phytochemical composition raising hopes of finding potential anticancer bioactive compounds from C. limon fruit peels.

What is the influence of policosanol supplementation on liver enzymes? A systematic review and dose-response meta-analysis of randomized controlled trials.

OBJECTIVE: Policosanol is a mixture of long chain alcohols refined from sugar cane. Significant reductions in liver enzymes have been observed in some studies. However, the impact of policosanol on liver enzymes remained controversial. The current meta-analysis aims to evaluate the effect of policosanol supplementation on the levels of alanine transaminase (ALT) and aspartate transaminase (AST). METHODS: The literature was systematically searched for studies published up to November 2023 in PubMed/Medline, Google Scholar, EMBASE, and Scopus. Randomized controlled trial (RCT) studies were included to evaluate the intervention effect of policosanol compared to placebo on ALT and AST. DerSimonian and Laird models were used to calculate effect sizes. RESULTS: Twenty-three trials including 2535 participants were included in the study. The combination of effect sizes, regarding the random-effects model, demonstrated significant changes in ALT serum levels after intervention (WMD: -1.48 U/L; 95% CI: -2.33 to -0.64; P = 0.001), and AST (WMD: -1.10 U/L; 95% CI: -1.70 to -0.51; P < 0.001). Subgroup analysis of AST and ALT showed that this reduction effect was most often observed at the dose of 20 mg/d. The dose-response analysis represented a non-significant non-linear connection between the dosage and duration of policosanol intervention in ALT and AST serum reduction. CONCLUSION: Policosanol supplementation exerts a beneficial effect on liver enzymes as well as ALT and AST concentrations in adults. However, further long-term and well-designed RCTs with better quality are needed to further assess and confirm these results.

Protective Effect of Hydroalcoholic Extract of Punica granatum Leaves on High Fructose Induced Insulin Resistance in Experimental Animals.

BACKGROUND: Insulin resistance (IR) is a condition characterized by reduced sensitivity of body tissues to insulin, leading to impaired regulation of downstream metabolic pathways and elevated blood glucose levels. Diets rich in fructose have been proven to cause insulin resistance in test rats, resulting in decreased insulin sensitivity, particularly in the liver, and compromised disposal of glucose from the body. In the search for effective treatments, Plant-derived formulations have gained popularity because to their ability for treating a variety of ailments. One such plant is Punica granatum Linn. from the Punicaceae family, which has long been used in the treatment of diabetes and its consequences. This study investigates the insulin-resistant activity of an extract from Punica granatum leaves. The study goal is to assess the possible protective role of Punica granatum against insulin resistance through various analyses, including serum glucose and insulin levels, lipid profile assessment, measurement of liver enzymes (ALP, SGOT, SGPT), and histopathological examination of liver sections. METHODS: The study involves several key methods to evaluate the insulin-resistant activity of Punica granatum extract in high fructose diet induced insulin resistance animal model. The extract was administered orally to the experimental animals. These methods include the measurement of serum glucose and serum insulin levels, analysis of the lipid profile, quantification of liver enzymes such as ALP, SGOT, and SGPT, and a detailed histopathological examination of liver tissue sections. These analyses collectively provide insights into the impact of Punica granatum extract on insulin resistance and related metabolic parameters. RESULTS: Findings of this study provide insight on the possible benefits of Punica granatum extract on insulin resistance. Through the assessment of serum glucose and insulin levels, lipid profile analysis, and measurement of liver enzymes, the study elucidates the impact of the extract on key metabolic indicators. Additionally, the histopathological examination of liver sections provides visual insights into the structural changes that may occur as a result of the treatment. CONCLUSION: In conclusion, this study highlights the ability of Punica granatum extract as a candidate for addressing insulin resistance. The findings suggest that the extract may have a protective role against insulin resistance, as evidenced by improvements in serum glucose and insulin levels, lipid profile, liver enzyme levels, and histopathological characteristics. Further research and investigations are warranted to fully understand the mechanisms underlying these observed effects and to validate the potential of Punica granatum extract as a therapeutic option for managing insulin resistance and its associated complications.

Effect of Ethanol Extract of Soursop (Annona muricata L.) Stem Bark on Rat Liver Function.

<b>Background and Objective:</b> Paracetamol does not cause toxic effects if given in therapeutic doses, namely below 4 g per day. Use of paracetamol at a dose of more than 4 g per day can result in hepatotoxicity. This study aims to compare the hepatoprotector potency of the ethanol extract of soursop stem bark (<i>A. muricata</i>) against the enzyme activity of SGOT and SGPT in rats induced by toxic doses of paracetamol. <b>Materials and Methods:</b> A Completely Randomized Design (CRD) comprised of 6 treatment groups and 3 replications. Total 27 white male rats were induced hepatotoxicity with 1350 mg of paracetamol on the 7th day, except for normal control (K0) which was given aquadest. The tested animals received akuades as the negative control (K-) 11.34 mg kg¹ b.wt., of Hepa-Q as the positive control (K+), ethanol extract stem bark <i>Annona muricata</i> at a dose of 150 mg kg¹ BB (P1), 300 mg kg¹ BB (P2) and 600 mg kg¹ BB (P3). <b>Results:</b> There was a significant difference (p<0.05) in the levels of SGOT and SGPT after giving ethanol extract of soursop (<i>A. muricata</i>) stem bark. The best treatment for reducing SGOT and SGPT levels in rats induced by paracetamol was the administration of ethanol extract of <i>A. muricata</i> stem bark at a dose of 600 mg kg¹ BB. <b>Conclusion:</b> Based on the results of the study, it was concluded that all ethanol extract of <i>Annona muricata</i> L. stem bark (EEAMSB) doses had the potential to reduce the levels of AST and ALT in paracetamol-induced rats.

Hepatoprotective effects of Alpinia officinarum rhizome extract on cisplatin-induced hepatotoxicity in rats: A biochemical, histopathological and immunohistochemical study.

BACKGROUND: Alpinia officinarum is a member of the ginger family (Zingiberaceae), which is widely cultivated in Asia and traditionally used for its anti-inflammatory, antimicrobial, and antihyperlipidemic qualities. This study aimed to evaluate the effect of Alpinia officinarum rhizome extract (AORE) on cisplatin (CP)-induced hepatotoxicity in rats. METHODS: Forty-four male rats were divided into six groups including the control group, AORE control group, CP control group, and three groups of CP (7 mg/kg dose, on the 10th day) with AORE (at concentrations of 100, 200 and 400 mg/kg, daily for 14 days). After 14 days, the rats' livers were removed and their liver function was assessed using biochemical marker enzymes including serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) activities and albumin, total protein, and total bilirubin (T. bilirubin). Oxidative stress was assessed by evaluating malondialdehyde concentration and hepatic superoxide dismutase activity, histopathological and immunohistochemical tests were also conducted. RESULTS: Results demonstrated that treatment with AORE reduced the toxicity in levels of the hepatic biomarkers in cp-induced groups. AORE treatment decreased oxidative stress and improved histopathological indexes. Furthermore, immunohistochemical (IHC) investigation showed the B-cell lymphoma 2 (Bcl-2) upsurging and p53 downregulating expression exhibiting the recovery following AORE administration. CONCLUSION: The founding suggested that AORE administration has positive biochemical, histopathological, and immunohistochemical impacts on the ameliorating of hepatotoxicity in CP-induced rats.

The Effect of Vitamin E Supplementation on Serum Aminotransferases in Non-Alcoholic Fatty Liver Disease (NAFLD): A Systematic Review and Meta-Analysis.

Νon-alcoholic fatty liver disease (NAFLD) is a common cause of end-stage liver disease in developed countries. Oxidative stress plays a key role during the course of the disease and vitamin E supplementation has shown to be beneficial due to its antioxidative properties. We aim to investigate the effect of vitamin E supplementation on serum aminotransferase levels in patients with NAFLD. Three electronic databases (MEDLINE, CENTRAL, and Embase) were reviewed for randomized trials that tested vitamin E supplementation versus placebo or no intervention in patients with NAFLD, published until April 2023. A total of 794 patients from 12 randomized trials were included in this meta-analysis. Notwithstanding the studies' heterogeneity and moderate internal validity in certain cases, among studies testing vitamin E supplementation at 400 IU/day and above, the values of alanine aminotransferase (ALT) were reduced compared with placebo or no intervention [ALT Mean Difference (MD) = -6.99 IU/L, 95% CI (-9.63, -4.35), for studies conducted in Asian countries and MD = -9.57 IU/L, 95% CI (-12.20, -6.95) in non-Asian countries]. Regarding aspartate aminotransferase (AST), patients in the experimental group experienced a reduction in serum levels, though smaller in absolute values [AST MD = -4.65 IU/L, 95% CI (-7.44, -1.86) in studies conducted in Asian populations] and of lower precision in non-Asian studies [MD = -5.60 IU/L, 95% CI (-11.48, 0.28)].

Successful Treatment of a Cervical Injury and Myopathy Using Integrative Medicine Techniques in an Eclectus Parrot (Eclectus roratus) Following Cervical Entrapment.

A 2-year-old female eclectus parrot (Eclectus roratus) was presented for suspected cervical myopathy due to trauma. Severe ventroflexion of the cervical spine and mental depression were identified during the physical examination. The bird was responsive to stimuli but otherwise quiet. Plasma biochemistry results were suggestive of a myopathy, based on marked elevations of both aspartate transaminase (25 652 U/L) and creatine kinase (253 240 U/L). Whole-body radiographic images were unremarkable. Treatment was initiated with supportive therapy for presumptive shock, dehydration, pain, myopathy, and possible spinal swelling. Allopathic therapy included subcutaneous fluids; vitamins A, D, and E; dexamethasone sodium phosphate; hydromorphone; and gavage feeding to treat the acute inflammatory process and provide nutritional support during healing. Supportive care through the Integrative Medicine Department (Louisiana State University, Baton Rouge, LA, USA) was also performed on the patient. Photobiomodulation, acupuncture, Tui-na massage, and rehabilitation exercises were instituted to provide adjunct treatment for relieving pain, promoting muscle healing, improving patient demeanor, and improving cervical mobility. Integrative therapies were well tolerated by the patient, with no sedation required. By day 3, mentation had subjectively improved by 50% despite the persistent cervical ventroflexion. By day 8, the elevated serum enzyme activities had decreased, the patient could eat and drink on its own, and it could readily step up and seek attention during handling. The bird was able to lift its head and could hold it at approximately 50% of normal posture. Integrative therapies were continued throughout hospitalization. The bird was released from the hospital 20 days after initial intake, with head carriage in approximately 80% of the expected normal position and no apparent cervical pain based on palpation. This case demonstrates the benefits of integrative therapies as an adjunct treatment for cervical pain and myopathy in a psittacine species.

Hepatoprotective and toxicological evaluation of tropical Sargassum polycystum C. Agardh collected from Sumbawa coast Indonesia, against carbon tetrachloride-induced liver damage in rats.

Pharmacological activities of seaweed, including its antioxidant effect, have been demonstrated and can protect macromolecules from xenobiotic-induced damage. Understanding the potency of seaweed as a hepatoprotection and its toxicity remains underexplored. The aims of this study were to investigate the antioxidant and hepatoprotective activity, as well as the toxicological potencies of S. polycystum ethyl acetate extract against carbon tetrachloride-induced liver damage in rats. Total phenolic content and total flavonoid contents were quantified using standard spectroscopy-based methods. The antioxidant activity was measured using 1,1-Diphenyl- 2-picryl Hydrazil scavenging radical, while the composition of compounds was identified by LCMS/MS. After seven days of post-administrated rats with S. polycystum ethyl acetate extract, the serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvate transaminase (SGPT) levels were tested. Total phenolic content, total flavonoid content and IC50 of S. polycystum ethyl acetate extract were 1.28±0.04 of GAE/g, 13.32±0.48 QE/g and 744.726µg/mL, respectively. S. polycystum ethyl acetate extract 150mg/kg BW provides a hepatoprotective effect with a significant improvement in the levels of SGOT (134.845 U/l±9.645) and SGPT (60.238 U/l ± 9.645) (p<0.05). S. polycystum ethyl acetate extract potentially protected the damage induced by CCl4 in the rat's liver at a certain concentration, while a higher extract concentration requires further examination.

[Effects of Li-Dan-He-Ji on regulating oxidative stress and antagonising infantile cholestatic hepatic fibrosis].

OBJECTIVE: To explore the clinical effect of Li-Dan-He-Ji in the treatment of infantile cholestatic hepatic fibrosis. METHODS: Patients who met the diagnostic criteria of infantile cholestatic hepatic fibrosis in the department of integrated traditional Chinese and Western medicine and the department of gastroenterology of Wuhan Children's Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from January to December 2021 were included in the study by prospective randomized controlled trial. They were divided into the conventional treatment group and Li-Dan-He-Ji group according to the random number table. The patients in the conventional treatment group were given conventional treatment according to the guidelines. In the Li-Dan-He-Ji group, the self-made Chinese medicinal compound Li-Dan-He-Ji (prescription: Herba Artemisiae Scopariae, Fructus Forsythiae, Radix et Rhizoma Rhei preparata, Radix Polygoni Multiflori Preparata, Radix Paeoniae Rubra, Ramulus Cinnamomi, Fructus Aurantii, Rhizoma Atractylodis Macrocephalae, Fructus Schisandrae Chinensis, Carapax Trionycis, and Radix Glycyrrhizae) was given on the basis of the routine treatment, by oral, enema or nasal feeding, 60 mL each day, divided into 2 or 3 times, for 28 days. Outpatient follow-up was maintained for 4 weeks. Before and after treatment, serum liver fibrosis 4 items [type IV collagen (IV-C), hyaluronidase (HA), type III procollagen (PC III), laminin (LN)], liver function and cholestasis-related markers [total bilirubin (TBil), direct bilirubin (DBil), total bile acid (TBA), alkaline phosphatase (ALP), γ-glutamyl transpeptidase (γ-GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST)], oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione (GSH)], liver stiffness measurement (LSM) detected by transient elastography (TE), aspartate aminotransferase-to-platelet ratio index (APRI), and liver and spleen retraction time were recorded in the two groups. RESULTS: During the observation period, a total of 40 cases of cholestatic hepatic fibrosis were treated, including 21 cases in the conventional treatment group and 19 cases in the Li-Dan-He-Ji group. Before treatment, the differences in serum liver fibrosis 4 items, serum liver function and cholestasis-related markers, oxidative stress indexes, LSM and APRI of the two groups were not statistically significant. After treatment, the liver fibrosis 4 items, liver function and cholestasis-related markers, LSM, and APRI were all significantly decreased in both groups, and the indexes in the Li-Dan-He-Ji group were significantly lower than those in the conventional treatment group [HA (ng/L): 165.81±21.57 vs. 203.87±25.88, PC III (µg/L): 69.86±9.32 vs. 81.82±7.39, IV-C (µg/L): 204.14±38.97 vs. 239.08±24.93, LN (µg/L): 162.40±17.39 vs. 190.86±15.97, TBil (µmol/L): 37.58±27.63 vs. 53.06±45.09, DBil (µmol/L): 20.55±19.34 vs. 30.08±27.39, ALP (U/L): 436.50±217.58 vs. 469.60±291.69, γ-GGT (U/L): 66.78±35.84 vs. 87.00±32.82, ALT (U/L): 64.75±50.53 vs. 75.20±50.19, AST (U/L): 77.25±54.23 vs. 96.80±59.77, TBA (µmol/L): 74.35±44.44 vs. 85.45±39.50, LSM (kPa): 5.24±0.39 vs. 7.53±3.16, APRI: 0.52±0.39 vs. 0.98±0.29, all P < 0.05]. After treatment, MDA in the two groups were significantly lower than those before treatment, and SOD and GSH were significantly higher than those before treatment. The level of SOD in the Li-Dan-He-Ji group was significantly higher than that in the conventional treatment group (kU/L: 64.56±6.69 vs. 51.58±5.98, P < 0.05). In addition, the liver retraction time (day: 20.13±10.97 vs. 24.33±13.46) and spleen retraction time (day: 25.93±13.01 vs. 29.14±14.52) in the Li-Dan-He-Ji group were significantly shorter than those in the conventional treatment group (both P < 0.05). CONCLUSIONS: The use of Li-Dan-He-Ji in the treatment of cholestatic hepatic fibrosis can effectively improve the indicators of cholestasis, hepatic fibrosis, oxidative stress and clinical symptoms in children.

Swertia bimaculata moderated liver damage in mice by regulating intestine microbiota.

Swertia bimaculata (SB) is a medicinal herb in China having an array of therapeutic and biological properties. This study aimed to explore the attenuating effect of SB on carbon tetrachloride (CCl4) induced hepato-toxicity by regulation of gut microbiome in ICR mice. For this purpose, CCl4 was injected intraperitoneally in different mice groups (B, C, D and E) every 4th day for a period of 47 days. Additionally, C, D, and E groups received a daily dose (50 mg/kg, 100 mg/kg, and 200 mg/kg respectively) of Ether extract of SB via gavage for the whole study period. The results of serum biochemistry analysis, ELISA, H&E staining, and sequencing of the gut microbiome, indicated that SB significantly alleviates the CCl4-induced liver damage and hepatocyte degeneration. The serum levels of alanine transaminase, aspartate aminotransferase, malondialdehyde, interleukin 1 beta and tumor necrosis factor-alpha were significantly lower in SB treated groups compared to control while levels of glutathione peroxidase were raised. Also, the sequencing data indicate that supplementation with SB could restore the microbiome and its function in CCl4-induced variations in intestinal microbiome of mice by significantly downregulating the abundances of pathogenic intestinal bacteria species including Bacteroides, Enterococcus, Eubacterium, Bifidobacterium while upregulating the levels of beneficial bacteria like Christensenella in the gut. In conclusion, we revealed that SB depicts a beneficial effect against hepatotoxicity induced by CCl4 in mice through the remission of hepatic inflammation and injury, through regulation of oxidative stress, and by restoring gut microbiota dysbiosis.

Hepatoprotective activity of ethanolic extract of Plectranthus amboinicus (lour.) spreng leaf in DMBA induced rats.

The hepatoprotective activity of ethanolic of Plectranthus amboinicus Lour Spreng leaf extract (PEE) on blood biochemical profiles, non-specific immune system, liver histology were evaluated in rats induced DMBA. Twenty five female rats were divided into five groups, each with 5 rats. The negative control group (NC) received only food and water. The positive control group (PC) administered orally DMBA 20 mg/kg body weight (bw) once every four days for 32 days. The treatment groups received the PEE with three different doses of 175 (T1), 350 (T2), 700 (T3) mg/kg bw, respectively for 27 days after DMBA induction. At the end of the treatment, blood samples were collected to investigate the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin, total protein, albumin and globulin as well as the hematological parameter, such as neutrophils, monocyte, mean corpuscular hemoglobin (MCH), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), and red cell distribution width (RDW) were monitored. The results showed an increased level in ALT, AST, ALP, and bilirubin in the PC group. However, the T3 group (PEE 700 mg/kg) showed a significant decrease value (p < 0.05) in ALT, ALP, and bilirubin compared to the PC group. Our finding revealed that all PEE treatments had a significant increase (p < 0.05) in the total protein, albumin and globulin compared to the PC group. The neutrophils (18.60 ± 4.64) and monocytes (61.40 ± 4.99) are lowest in the T2 groups as well as the value of MCH, RDW and MCV were significantly alleviated compared to all other groups. Histopathological observation demonstrated that the administration of PEE improved hepatocyte architecture and reduced the number of necrosis and hydrophilic degeneration. In conclusion, PEE has hepatoprotective activity by improving liver function, enhancing the non-specific immune system and recovering histopathological hepatocytes in rats exposed to DMBA.

Serum metabolome profiling, network pharmacology analysis, and experimental validation of Anoectochilus roxburghii in the treatment of carbon tetrachloride-induced liver injury.

Anoectochilus roxburghii (Wall.) Lindl. (AR) has been traditionally used to treat inflammatory diseases, but the specific mechanism underlying its hepatoprotective effect remains unclear. Here, serum metabolomics and network pharmacology were employed to investigate the hepatoprotective mechanism of AR. Thirty male Sprague-Dawley rats were divided into six groups: normal, model, positive, high-dose AR, middle-dose AR, and low-dose AR. The positive group received therapeutic doses of silibinin, whereas the AR-treated groups received different doses of AR extract once daily. After 10 days of intragastric administration, the rats were intraperitoneally injected with a 50% CCl4 olive oil solution (2 mL/kg) to induce liver injury. Serum and liver samples were obtained, and GC-MS was utilized to monitor changes in serum metabolome. The levels of alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, and hydrooxproline in serum significantly increased in the model group. On the contrary, AR-treated group showed a significant decrease in the levels of alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, and hydrooxproline. Histopathological observation also revealed that the extent of liver injury was alleviated in the AR-treated group. Fifty differential metabolites were identified, suggesting that AR may prevent liver damage by modulating carbohydrate and amino acid metabolism.

The Effect of Royal Jelly on Telomere Length and Some Biochemical Parameters in Wistar Albino Rats with Liver Damage Caused by Carbon Tetrachloride.

Royal jelly (RJ) is a natural bee product that has been used for therapeutic purposes since ancient times. The therapeutic properties of this product, which has rich biological content, are still being investigated with new approaches. In this study, the effect of RJ on telomere length, some antioxidant parameters, and lipid profile was examined. This study will contribute to the literature as it is the first to evaluate the effect of RJ on the length of telomeres in damaged liver tissues. In the study, the levels of serum triglyceride, total cholesterol (TC), high-density lipoprotein cholesterol, low-density lipoprotein cholesterol (LDL-C), aspartate transaminase (AST), alanine transaminase (ALT), telomerase, 8'-hydroxy-2'-deoxyguanosine (8-OHdG), and paraoxonase-1 (PON1) were investigated with enzyme-linked immunosorbent assay method and telomere lengths were investigated by real-time quantitative polymerase chain reaction. The increased TC, LDL-C levels, and AST and ALT activities in the serum after carbon tetrachloride (CCl4) administration approached the control level after RJ administration. PON1 activity decreased in groups with CCl4. PON1 activity increased after RJ administration. The level of 8-OHdG, which increased groups with CCl4, decreased after RJ administration. According to the results of telomere length analysis in liver tissues, telomere lengths in damaged tissues were significantly shortened with CCl4 application and increased with RJ application. Based on the findings of the study, it was concluded that RJ may have therapeutic effects on telomere lengths and some biochemistry parameters.
