[PMID: 38356556 PMCID: PMC10864916 DOI: 10.1016/j.heliyon.2024.e25340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 01/22/2024] [Accepted: 01/24/2024] [Indexed: 02/16/2024] Open
Abstract
The liver is an essential organ that helps the body with immunity, metabolism, and detoxification, among other functions. Worldwide, liver illnesses are a leading cause of mortality and disability. There are few effective treatment choices, but they frequently have unfavorable side effects. Investigating the potential of medicinal plants and their bioactive phytoconstituents in the prevention and treatment of liver disorders has gained more attention in recent years. An assessment of the hepatoprotective potential of medicinal plants and their bioactive secondary metabolites is the goal of this thorough review paper. To determine their hepatoprotective activity, these plants were tested against liver toxicity artificially induced in rats, mice and rabbits by chemical agents such as carbon tetrachloride (CCl4), paracetamol (PCM), thioacetamide (TAA), N-nitrosodiethylamine, d-galactosamine/lipopolysaccharide, antitubercular medicines (rifampin, isoniazid) and alcohol. To find pertinent research publications published between 1989 and 2022, a comprehensive search of electronic bibliographic databases (including Web of Science, SpringerLink, ScienceDirect, Google Scholar, PubMed, Scopus, and others) was carried out. The investigation comprised 203 plant species from 81 families in total. A thorough discussion was mentioned regarding the hepatoprotective qualities of plants belonging to several families, such as Fabaceae, Asteraceae, Lamiaceae, and Euphorbiaceae. The plant groups Asteraceae and Fabaceae were the most frequently shown to have hepatoprotective properties. The phytochemical constituents namely flavonoids, phenolic compounds, and alkaloids exhibited the highest frequency of hepatoprotective action. Also, some possible mechanism of action of some active constituents from medicinal plants was discussed in brief which were found in some studies. In summary, the information on medicinal plants and their potentially hepatoprotective bioactive phytoconstituents has been consolidated in this review which emphasizes the importance of further research to explore the efficacy and safety of these natural remedies for various liver ailments.

Abstract
Introduction : Diabetes Mellitus is a major health problem characterized by hyperglycemia and disturbances in metabolism and implicated in causing oxidative stress. Treatment includes administration of oral hypoglycaemic agents with lifestyle modifications, these offer glycemic control, however, present limitations about availability, affordability and side effects. Traditional anti-diabetic plants are becoming popular in management of diabetes mellitus. This study was carried out to determine the efficacy of Leptadenaia hastata in treatment of diabetes. Materials and methods Diabetes mellitus was induced in using a single injection of streptozotocin (50 mg kg- 1 i.p.). The rats were divided into four groups of 5 rats each. Groups 3-6 received olive oil, 100 mg kg- 1 extract, 200 mg.kg- 1 extract and insulin (6IU kg- 1), respectively. 10 non-diabetic rats were grouped into two group receiving olive oil and 200 mg kg- 1 extract for 28 days. All groups were sacrificed by injecting with ketamine hydrochloride, blood was collected by cardiac puncture and centrifuged. The serum was analyzed for biochemical parameters. The liver was removed and homogenized with the supernatant of the resultant homogenate collected and used for analysis of oxidative stress enzymes. Results The extract significantly decreased serum AST (p < 0.05), ALP (p < 0.001), ALT (p < 0.05), TG (p < 0.01), TC (p < 0.001), creatinine (p < 0.001). It had no effect on SOD and CAT levels but it significantly increased (p < 0.001) GSH levels and reduced (p < 0.05) MDA level. Conclusions The n-hexane extract of Leptadenia hastata significantly decreased the levels of hepatic and renal serum biomarkers proving that it was beneficial in ameliorating diabetic related complications. The extract significantly increased GSH levels and reduced MDA level. Supplementary Information The online version contains supplementary material available at 10.1007/s40200-022-01017-z.

Abstract
OBJECTIVES Several studies have established the ethnobotanical benefits of Pupalia lappacea (PL) in laboratory animals without extensive toxicological evaluation of its safety profiles. Thus, an extensive toxicological investigation of sub-chronic oral administration of the hydroethanol leaf extract of P. lappacea in rodents was carried out in this study. METHODS Different groups of rats were treated orally with the extract (10, 50 and 250 mg/kg) daily for 90 consecutive days. The control group received distilled water (10 mL/kg). After 90 days, some rats were left for additional 30 days without treatment for reversibility study. Blood and organs samples were collected for different evaluations at the end of study periods. RESULTS The extract decreased the bodyweights, feeding and water intakes in female rats. PL increased the weights of the liver and kidney in male rats. PL increased the red blood cell (RBC), packed cell volume (PCV), hemoglobin (Hb), triglycerides (TRIG), cholesterol and high density lipoprotein (HDL) contents in rats. PL (250 mg/kg) significantly reduced the sperm motility and serum testosterone level. Cyto-architectural distortions of the testes, liver and spleen were visible. CONCLUSIONS The findings showed that P. lappacea is relatively safe at lower doses but cautions should be taken at higher dose.

Four almost unexplored species of Brazilian Connarus (Connaraceae): Chemical composition by ESI-QTof-MS/MS-GNPS and a pharmacologic potential. PHYTOCHEMICAL ANALYSIS : PCA 2022; 33:286-302. [PMID: 34510611 DOI: 10.1002/pca.3087] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 07/21/2021] [Accepted: 08/02/2021] [Indexed: 06/13/2023]
Abstract
INTRODUCTION Species of Connaraceae are globally used in traditional medicines. However, several of these have not been studied regarding their chemical composition, and some are even at risk of extinction without proper studies. Therefore, the chemical composition and pharmacological potential of Connarus blanchetii Planch., Connarus nodosus Baker, Connarus regnellii G. Schellenb., and Connarus suberosus Planch., which were previously unknown, were analyzed. OBJECTIVE This work aims to investigate the pharmacological potential of these four Connarus species. The chemical composition of different extracts was determined by high-resolution mass spectrometry (HRMS), with subsequent analysis by the GNPS platform and competitive fragmentation modeling (CFM). MATERIALS AND METHODS Leaf extracts (C. blanchetii, C. nodosus, C. regnellii, and C. suberosus) and bark extracts (C. regnellii and C. suberosus) were obtained by decoction, infusion, and maceration. LC/HRMS data were submitted to the GNPS platform and evaluated using CFM in order to confirm the structures. RESULTS The HRMS-GNPS/CFM analysis indicated the presence of 23 compounds that were mainly identified as phenolic derivatives from quercetin and myricetin, of which 21 are unedited in the Connarus genus. Thus, from the analyses performed, we can identify different compounds with pharmacological potential, as well as the most suitable forms of extraction. CONCLUSION Using HRMS-GNPS/CFM, 21 unpublished compounds were identified in the studied species. Therefore, our combination of data analysis techniques can be used to determine their chemical composition.

Abstract
Aim: The present study intended to compare the antioxidant, anti-lipid peroxidation, and anti-inflammatory potentials of Nigella Sativa (NS) and onion extract on 5-FU-induced liver damage in rats. Material and methods: 48 rats were divided into control, control group of the onion extract, control group of the NS extract, 5-FU-treated, concomitant NS-treated, and concomitant onion extract-treated. Liver sections were processed for histological analysis (light and electron microscopic examination). Liver enzymes (ALT, AST, and ALP), inflammatory markers (TNF-α and IL-1), antioxidant markers (SOD, GSH, and GSH/GSSG ratio), 4-HNE, NF-κB, and Nrf2 were evaluated. Results: The 5-FU-treated group exhibited inflammation, congested hepatic sinusoid, and steatosis. Improvement with few pathological residues was seen in the concomitant extract-treated groups. The 5-FU-treated group showed higher liver enzymes. The enzymes decreased in the concomitantly treated groups. 5-FU induced liver damage through oxidative stress, inflammation, and lipid peroxidation. Concomitantly using NS and onion extracts resulted in a reduction in oxidative stress, lipid peroxidation, and inflammation. Conclusion: NS and onion extracts attenuated 5-FU-induced liver damage via antioxidative, anti-lipid peroxidative, and anti-inflammatory mechanisms. NS's role was exceptional when compared with onion extract.

Abstract
Abstract
Background
Carbon tetrachloride (CCl4) is a well-characterized hepatotoxic agent. With rising cases of liver diseases, the identification, assessment, and development of hepatoprotective agents from plants source has become imperative.
Main body
With arrays of literature on plants with hepatoprotective potentials, this review sourced published literatures between 1998 and 2020 and systematically highlighted about 92 medicinal plants that have been reported to protect against CCl4-induced liver injury in animal models. The results show that herbal plants provide protection for the liver against CCl4 by downregulation of the liver marker enzymes and activation of antioxidant capacity of the liver cells with the restoration of liver architecture. We also provided the traditional and accompanying pharmacological uses of the plants. A variety of phytochemicals mostly flavonoids and polyphenols compounds were suggested to offer protection against liver injuries.
Conclusion
It can be concluded that there are a variety of phytochemicals in plant products with hepatoprotective activity against CCl4-induced toxicity in animal models.

Abstract
To explore the mechanism of renal toxicity induced by florfenicol (FFC), 120 chicks were randomly divided into 6 groups, 20 in each group. Except for the control group, different doses of FFC (0.15 g/L, 0.3 g/L, 0.6 g/L, 1.2 g/L, and 1.8 g/L) were added to drinking water in the other 5 groups. Five days later, blood was collected from the vein under the wing, and the complete kidneys were obtained as soon as possible, then tested the experimental indicators. The results showed that compared with control group, all doses of FFC significantly reduced the average weight gain of chicks (P < 0.05 or P < 0.01). Except for the 0.15 g/L FFC group, kidney index of chicks in the other doses of FFC groups were significantly increased (P < 0.05 or P < 0.01). The kidney tissues in all FFC groups showed obvious damage, deformities, cell atrophy, and cell gap enlargement. In addition, all doses of FFC significantly increased the contents of uric acid (UA), blood urea nitrogen (BUN), creatinine (CRE) in serum, and malondialdehyde (MDA) in renal tissue (P < 0.05 or P < 0.01), but significantly reduced the levels of glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) in renal tissue (P < 0.05 or P < 0.01). FFC significantly inhibited the mRNA and protein expression levels of nuclear factor-erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and nicotinamide adenine dinucleotide phosphate: quinone oxidoreductase-1 (NQO-1), and increased the mRNA and protein expression levels of p53, Caspase-3, and Caspase-6 (P < 0.05 or P < 0.01). The apoptotic rate of renal cells in all doses of FFC groups increased significantly (P < 0.05 or P < 0.01). It was concluded that FFC had a certain degree of nephrotoxicity, and with the increase of FFC concentration, the kidney injury of chicks became more and more serious. FFC promoted oxidative stress response in kidney of chicks by inhibiting the expression of related factors in Nrf2-ARE pathway. Moreover, the expression of pro-apoptotic factors was upregulated to improve the apoptosis rate of renal cells, which resulted in excessive apoptosis of renal cells and seriously affected the kidney function of chicks.

Connaraceae: An updated overview of research and the pharmacological potential of 39 species. JOURNAL OF ETHNOPHARMACOLOGY 2020; 261:112980. [PMID: 32422354 DOI: 10.1016/j.jep.2020.112980] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Revised: 05/01/2020] [Accepted: 05/12/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE An interdisciplinary scientific investigation of biologically active agents is fundamental to search for natural substances with therapeutic action. This review collected the most relevant information on traditional knowledge related to the use of plants of the Connaraceae family. This work is the first to compile all the published ethnobotanical, chemical, pharmacological, and toxicological information about this important plant family. AIM OF THE STUDY Our objective was to provide the scientific community with an up-to-date overview of the pharmacological potential of Connaraceae species. MATERIAL AND METHODS We searched NCBI Pubmed Central, Google Scholar, Scientific Electronic Library Online (SciELO), ScienceDirect, SciFinder, and Scopus databases to review the research on ethnobotanical, chemical, pharmacognostical, pharmacological, and toxicological studies with Connaraceaes. Books that address the theme were also included. DISCUSSION AND CONCLUSION The literature review indicated that 39 species of Connaraceaes have pharmacological potentiality. Ethnobotany reports listed 36 of the 39 species discussed. Pharmacognostical studies have been conducted with 23 species and isolates, and chemical compounds have been identified for only 15 species. At least one study has been published concerning the pharmacological activities for 20 of the 39 species analyzed. For Agelaea pentagyna, Cnestis ferruginea, Connars suberosus, and Rourea minor, pharmacological activity experiments were performed using isolated compounds, which have the highest current pharmacological potential. Studies employing a toxicological approach cover only 10 of the 39 Connaraceaes species. Thus, scientific community should conduct much more research for a broader understanding of this plant family.

Abstract
Background Ovarian cancer (OvCa) is one of the most lethal tumors of gynecologic malignancies, due to lack of early detection, and a high rate of metastasis. The standard treatment for OvCa is surgery and cytotoxic chemotherapy. However, to overcome the high cost and side effects of these treatments, medicinal plants are widely used in developing countries to treat OvCa. Byrsocarpus coccineus plant preparation has been administered to patients traditionally in the management of tumors in Nigeria. In this study, we investigated the anti-proliferative effects of B. coccineus ethanol leaf extract against OVCAR-3 and SW 626 OvCa cell lines. After the treatment of the two cell lines with the extracts, analyses were carried out to determine inhibition of proliferation and expression of cell cycle markers, pro-apoptotic, and anti-apoptotic markers. Results Results showed that B. coccineus ethanol leaf extract, significantly inhibited cell migration and colony formation in OVCAR-3 and SW 626 treated cells in a dose-dependent manner. Results also show that B. coccineus ethanol leaf extract modulated the expression of tumor suppressor gene (p53), cell cycle progression, pro- and anti-apoptotic gene, and the pro-inflammatory cytokines. Conclusions These results suggest that B. coccineus have anti-proliferative properties and could induce apoptosis. Further investigation will be carried out to isolate bioactive compounds for the treatment of ovarian cancer.

Abstract
BACKGROUND AND AIMS P-Coumaric acid (PCA) is one the compound that has free radical scavenging effects. This study investigates the protective effect of PCA on tissue damage in DOX-induced nephrotoxicity. METHODS Thirty two Wistar rats were divided into control, PCA, DOX (15 mg/kg, i.p.) and DOX plus PCA (100 mg/kg, orally) groups. DOX-induced nephrotoxicity was indicated by marked increase in blood urea nitrogen (BUN) and serum creatinine (Cr) compared to controls. DOX group also showed elevations in lipid peroxidation and reductions in enzyme activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT). Expression of renal inflammatory cytokines including tumor necrosis factor alpha (TNF-α) and interleukin-1 beta (IL-1β) and apoptosis were also elevated in the DOX group. RESULTS PCA significantly reversed, nephrotoxicity induced by DOX via lowering BUN, serum Cr and improving histopathological scores as compared to the DOX group. PCA also decreased lipid peroxidation, increased activities of GPx, SOD and CAT, to levels relatively comparable to control. Significant reductions in expression of TNF-α, IL-1β and apoptosis were also observed following Co-administration of PCA relative to the DOX group. CONCLUSIONS Results describe a protective effect of PCA against DOX-induced nephrotoxicity. This effect is likely facilitated through inhibition of oxidative stress, inflammation and apoptosis.

Ameliorative effect of supercritical fluid extract of Chrysanthemum indicum Linnén against D-galactose induced brain and liver injury in senescent mice via suppression of oxidative stress, inflammation and apoptosis. JOURNAL OF ETHNOPHARMACOLOGY 2019; 234:44-56. [PMID: 30610932 DOI: 10.1016/j.jep.2018.12.050] [Citation(s) in RCA: 40] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/02/2018] [Revised: 12/28/2018] [Accepted: 12/30/2018] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chrysanthemum indicum Linne (C. indicum), a healthy food and folk medicine in China for thousands of years, has been reported to exert heat-clearing and detoxifying effects and extensively applied to treat various symptoms such as inflammation diseases, hepatitis and headache. AIM OF THIS STUDY The purpose of the present study was to investigate the protective effect of the supercritical carbon dioxide fluid extract from flowers and buds of C. indicum (CISCFE) on D-galactose-induced brain and liver damage during aging process and to illuminate the underlying mechanisms. MATERIALS AND METHODS Mice were orally administrated with CISCFE (100, 150 and 300 mg/kg) after injection with D-galactose. 24 h after the last administration, the blood samples, whole brain and liver tissues were collected for biochemical analysis, histological examination and western blot analysis. The body weight, spleen and thymus indexes, alanine transaminase (ALT), aspartate transaminase (AST), total antioxidant capacity (T-AOC), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), malondialdehyde (MDA) in brain and liver, interleukin-1β (IL-1β), interleukin-6 (IL-6), and necrosis factor-α (TNF-α) were detected. Besides, the expressions of Bax, Bcl-2 and cleaved caspase-3 were determined by western blot assay. RESULTS The results indicated that CISCFE effectively increased the suppressed body weight, attenuated the decline of thymus and spleen indexes, and reduced the elevated levels of ALT and AST induced by D-gal. Furthermore, CISCFE might notably alleviate D-gal-induced abnormal alterations in structure and function of brain and liver dose-dependently via renewing normal antioxidant enzymes activities (SOD, CAT, GSH-Px), reducing MDA accumulation, decreasing inflammatory cytokines productions (IL-1β, IL-6, TNF-α), as well as attenuating the increase of Bax/Bcl-2 ratio and cleaved caspase-3 activation in the liver and brain. CONCLUSIONS Taken together, our present results suggested that CISCFE treatment could effectively mitigate the D-gal-induced hepatic and cerebral injury, and the underlying mechanism might be tightly related to the decreased oxidative stress, inflammation and apoptosis, indicating CISCFE might be an alternative and promising agent for the treatment of aging and age-associated brain and liver diseases.

Protective effect of carvedilol alone and coadministered with diltiazem and prednisolone on doxorubicin and 5-fluorouracil-induced hepatotoxicity and nephrotoxicity in rats. Pharmacol Res Perspect 2018; 6. [PMID: 29417758 PMCID: PMC5817834 DOI: 10.1002/prp2.381] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Accepted: 11/30/2017] [Indexed: 01/07/2023] Open
Abstract
This study investigated the protective effects of carvedilol alone and coadministered with prednisolone and diltiazem on doxorubicin (DOX) and 5‐fluorouracil (5‐FU)‐induced toxicity. Each of 2 pools of 70 female rats were randomly allotted into 10 groups of 7 animals each and treated as follows: Group 1: normal saline (10 mL/kg); Group 2: normal saline and DOX (40 mg/kg)/5‐FU (20 mg/kg) alone; Group 3: gallic acid (200 mg/kg) and DOX/5‐FU; Group 4: carvedilol (0.075 mg/kg) and DOX/5‐FU; Group 5: carvedilol (0.15 mg/kg) and DOX/5‐FU; Group 6: carvedilol (0.30 mg/kg) and DOX/5‐FU; Group 7: diltiazem (3.43 mg/kg) and DOX/5‐FU; Group 8: diltiazem (3.43 mg/kg), carvedilol (0.15 mg/kg), and DOX/5‐FU; Group 9: prednisolone (0.57 mg/kg) and DOX/5‐FU; and Group 10: prednisolone (0.57 mg/kg), carvedilol (0.15 mg/kg), and DOX/5‐FU. Treatments were done p.o. for 16/14 days for the DOX/5‐FU models. DOX/5‐FU was administered i.p. to the rats in Groups 2‐10 on day 14/10‐14. On day 17/15 (DOX/5‐FU), blood samples were collected, and liver and kidneys of rats were harvested for antioxidant and histopathological assessments. Carvedilol alone and coadministered with prednisolone significantly (P < .05) decreased alanine aminotransferase level compared with administration of DOX alone. Carvedilol alone and coadministered with diltiazem significantly (P < .05) decreased creatinine level compared with administration of DOX/5‐FU alone. Carvedilol alone and coadministered with diltiazem and prednisolone significantly (P < .05) increased the level of hepatic superoxide dismutase and catalase, and decreased malondialdehyde compared with DOX administration alone. Histopathological observations correlated with results of biochemical and antioxidant analyses. Carvedilol administered alone and coadministered with diltiazem and prednisolone reduced the effect of DOX/5‐FU‐induced hepatic and renal toxicities due to enhanced in vivo antioxidant activity. The protective effect was more prominent in the doxorubicin model compared with the 5‐fluorouracil test. Coadministration of carvedilol with either diltiazem or prednisolone did not show better protection relative to carvedilol alone.

Abstract
Malvaviscus arboreus Cav. is a medicinal plant belonging to family Malvaceae with both ethnomedical and culinary value; however, its phytochemical and biological profiles have been scarcely studied. Accordingly, this work was designed to explore the chemical composition and the hepatoprotective potential of M. arboreus against carbon tetrachloride (CCl4)-induced hepatotoxicity. The total extract of the aerial parts and its derived fractions (petroleum ether, dichloromethane, ethyl acetate, and aqueous) were orally administered to rats for six consecutive days, followed by injection of CCl4 (1:1 v/v, in olive oil, 1.5 ml/kg, i.p.) on the next day. Results showed that the ethyl acetate and dichloromethane fractions significantly alleviated liver injury in rats as indicated by the reduced levels of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bilirubin (TB), and malondialdehyde (MDA), along with enhancement of the total antioxidant capacities of their livers, with the maximum effects were recorded by the ethyl acetate fraction. Moreover, the protective actions of both fractions were comparable to those of silymarin (100 mg/kg), and have been also substantiated by histopathological evaluations. On the other hand, liquid chromatography-high resolution electrospray ionization mass spectrometry (LC‒HR‒ESI‒MS) metabolomic profiling of the crude extract of M. arboreus aerial parts showed the presence of a variety of phytochemicals, mostly phenolics, whereas the detailed chemical analysis of the most active fraction (i.e. ethyl acetate) resulted in the isolation and identification of six compounds for the first time in the genus, comprising four phenolic acids; β-resorcylic, caffeic, protocatechuic, and 4-hydroxyphenylacetic acids, in addition to two flavonoids; trifolin and astragalin. Such phenolic principles, together with their probable synergistic antioxidant and liver-protecting properties, seem to contribute to the observed hepatoprotective potential of M. arboreus.

Abstract
The effects of aqueous extract of Brysocarpus coccineus roots (AEBCR) were studied on sexual behaviour and testicular function of paroxetine-induced sexual dysfunction (SD) in male rats. Ninety, sexually matured male rats (150.88 ± 5.53 g) were assigned into two groups: A and B. Fifteen SD animals from group B were each allotted to B1, B2, B3, B4 and B5 and received distilled water (DW), Powmax M (7.14 mg/kg body weight, b.w.) 50, 100 and 150 mg/kg b.w of AEBCR, respectively, for 7 days while the non-SD animals (group A) received DW. Eleven secondary metabolites were present in AEBCR. The lowered (p < .05) ejaculation frequency, penile erection index and penile grooming, higher mount and intromission frequencies, prolonged (p < .05) latencies of mount, intromission, ejaculation, and post-ejaculatory interval, reduced (p < .05) serum luteinising hormone, follicle stimulating hormone, testosterone, nitric oxide and testicular function indices, degenerated seminiferous tubules and low luminal spermatozoa contents by paroxetine were significantly (p < .05) attenuated and/or reinstated by AEBCR and Powmax M. The restoration of androgen-dependent sexual and testicular functions in SD male rats by AEBCR validates its folkloric use as aphrodisiac. Clinical studies are desirable to ascertain the efficacy of AEBCR in SD.

Abstract
BACKGROUND Hepatitis is a liver inflammation caused by different agents and remains a public health problem worldwide. Medicinal plants are an important source of new molecules being considered for treatment of this disease. Our work aims at evaluating the hepatoprotective properties of Neoboutonia velutina, a Cameroonian medicinal plant. METHODS The aqueous extract has been prepared using phytochemical methods. HepG2 cells were used to assess anti-inflammatory properties of the extract at different concentrations. Acute hepatitis models (Carbon tetrachloride and Concanavalin A) were performed in mice receiving or not receiving, different extract doses by gavage. Liver injury was assessed using histology, transaminases and pro-inflammatory markers. Extract antioxidant and radical scavenging capacities were evaluated. RESULTS The extract led to a significant decrease in pro-inflammatory cytokine expression in vitro and to a remarkable protection of mice from carbon tetrachloride-induced liver injury, as shown by a significant decrease in dose-dependent transaminases level. Upon extract treatment, inflammatory markers were significantly decreased and liver injuries were limited as well. In the Concanavalin A model, the extract displayed weak effects. CONCLUSIONS Taking into account underlying mechanisms in both hepatitis models, we demonstrate the extract's radical scavenging capacity. Neoboutonia velutina displays a potent hepatoprotective effect mediated through radical scavenging properties.

Abstract
Background: Due to its nutritional and medicinal values, the leaf of Telfairia occidentalis Hook f. (Cucurbitaceae) is consumed in different parts of Nigeria. Acute and sub-chronic toxicity of the hydroethanolic leaf extract of Telfairiaoccidentalis were investigated in this study. Methods: Sixty-four male rats were randomized into four different groups of 16 animals each and were separately administered 80, 400 and 2000 mg/kg T. occidentalis orally (p.o.) for 60 days. Animals were sacrificed and blood samples were collected for hematological and biochemical analyses. Vital organs were harvested and evaluated for in vivo antioxidants and histopathological changes. Results: A significant (p < 0.05) reduction in weight of the testes, compared to the control group, was observed in the group treated with 2000 mg/kg extract. No significant change was observed in the weight of other vital organs relative to the control group. There were significant (p < 0.01) increases in sperm motility and count in the group administered 80 mg/kg extract and significant (p < 0.001) reductions in both parameters at 2000 mg/kg. There were significant increases in the levels of hemoglobin and packed cell volume at 80 and 2000 mg/kg of the extract. In respect of liver function parameters, significant reductions in aspartate aminotransferase and alanine aminotransferase levels at doses of 400 and 2000 mg/kg relative to control were observed. Compared to control, the extract significantly reduced (p < 0.05) the level of total cholesterol (400 mg/kg) and caused a significant increase in the level of high-density lipoprotein (80, 400 and 2000 mg/kg). Significant (p < 0.05) increase in the level of malondialdehyde, decrease in superoxide dismutase level and histopathological abnormalities were observed in the testes at 2000 mg/kg. Upon cessation of treatment with T. occidentalis for 30 days, the observed effects were reversed. Conclusions: The findings showed that the hydroethanolic leaf extract of Telfairia occidentalis is relatively non-toxic on acute and sub-chronic exposures at low to moderate doses, with the potential to elicit anti-anemic effects, reduce the risk of atherosclerosis and cardiovascular disease, and enhance antioxidant status in the brain and liver. Although possibly beneficial at low to moderate doses, the extract could be harmful to the testes with prolonged oral exposure at high dose.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ipomoea asarifolia (Convolvulacae), commonly known as "morning glory" is found across West Africa. Preparations of the plant are used traditionally for the treatment of diverse ailments including diabetes, neuralgia, arthritic pain and stomach ache. This study was designed to assess the safety profile of the hydroethanolic leaf extract of I. asarifolia through a 90-day subchronic toxicity study in rats. MATERIALS AND METHODS I. asarifolia was administered p.o. at doses of 40, 200 and 1000mg/kg to separate groups of rats for 90 days. Distilled water was given p.o. to rats in the control group. Some set of rats in each group were left for additional 30 days without administration of the extract for reversibility study. Animals were weighed weekly and relevant parameters were assayed at the end of the main and reversibility study periods. RESULTS There was no significant change (p>0.05) in the body weight of rats, and food and water intake in I. asarifolia treated groups compared with control. I. asarifolia (40-1000 mg/kg) significantly but reversibly reduced (p<0.05, 0.001) sperm motility and count. The extract did not generally cause significant change (p>0.05) in the weight of vital organs and haematological parameters except in the case of reversible reduction in the level of haemoglobin and red blood cell count (p<0.01; 40 mg/kg). The level of biochemical parameters and electrolytes were not significantly changed (p>0.05) except for the reversible reduction in the level of aspartate aminotransferase (AST; p<0.0001; 200 and 1000 mg/kg) and increase in the level of Na(+) (p<0.01; 200 mg/kg). The level of kidney reduced glutathione (GSH) was reversibly increased (p<0.01; 1000 mg/kg) while the level of enzymatic and non-enzymatic in vivo antioxidants was generally comparable and not significantly different (p>0.05) from control in respect of all other vital organs. Histological presentations were generally normal in respect of the liver, kidneys, brain, heart, lungs, pancreas, spleen and testes. CONCLUSIONS The findings in this study suggest that the hydroethanolic leaf extract of I. asarifolia is relatively safe administered orally for an extended period with potential renal in vivo antioxidant activities. However, the extract may cause reversible male sterility, anaemia and hypernatraemia.

Abstract
Prolonged zidovudine (AZT) treatment in HIV-infected and AIDS patients is shown to induce liver toxicity leading to complications. Therapeutic regimen that could encounter this adverse effect is unavailable and management of toxicity is often symptomatic or is limited to withdrawal of therapy. In the present investigation, we evaluated the alleviating properties of silibinin (SBN), a flavanolignan obtained from Silybum marianum against subacute AZT-induced hepatotoxicity and oxidative stress in rats. AZT treatment (50 mg/kg body weight (b.w.) periorally (p.o.), daily for 45 days) caused highly significant increases in alanine transaminase, alkaline phosphatase, argininosuccinic acid lyase and bilirubin in serum. Oxidative stress is shown by a highly significant increase in lipid peroxidase and total carbonyl content and decrease in catalase and protein thiols in the liver tissue. Hyperlipidaemia is indicated by highly significant increase in total lipids and free fatty acid in serum. Evaluation of liver by haematoxylin and eosin staining shows parenchymal cell enlargement, inflammatory changes and increase in sinusoidal spaces. Simultaneous treatment of SBN (100 mg/kg b.w. p.o., daily for 45 days) significantly protected the liver against hepatotoxicity, oxidative stress and hyperlipidaemia induced by AZT, and this alleviating property is attributed to hepatoprotective, membrane-stabilizing, antioxidant and free radical scavenging properties of SBN.

[PMID: 24684352 DOI: 10.1111/1440-1681.12230] [Citation(s) in RCA: 71] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2014] [Revised: 03/02/2014] [Accepted: 03/16/2014] [Indexed: 12/11/2022]
Abstract
The possible protective effects of naringenin, a naturally occurring citrus flavonone, on carbon tetrachloride (CCl4 )-induced liver injury in rats and the mechanism underlying its effects were investigated. Forty rats were divided into five groups. Rats in Groups I and II served as the normal and injured liver groups, respectively; Group III rats were treated with the standard drug silymarin as a positive control; and rats in Groups IV and V (naringenin-treated groups) were administrated 50 mg/kg, p.o., naringenin for 7 days. Liver samples were collected to evaluate mRNA and protein expression, histological changes and oxidative stress. Naringenin inhibited lipid peroxidation and reduced serum levels of hepatic enzymes induced by CCl4 . In addition, naringenin increased the liver content of reduced glutathione and the activity of anti-oxidant enzymes in rats treated with CCl4 . Naringenin attenuated liver inflammation by downregulating CCl4 -induced activation of tumour necrosis factor (TNF)-α, inducible nitric oxide synthase (iNOS) and cyclo-oxygenase (COX-2) at both the protein and mRNA levels. Naringenin treatment significantly increased NF-E2-related factor 2 (Nrf2) and heme oxygenase (HO-1) expression in injured livers. In rats treated with CCl4 alone, decreases were seen in nuclear Nrf2 expression and in the mRNA levels of its target genes (e.g. HO-1, NQO1 and glutathione S-transferase alpha 3 (GST-a3)). Together, the results suggest that naringenin can protect the liver against oxidative stress, presumably by activating the nuclear translocation of Nrf2 as well as attenuating the TNF-α pathway to elicit an anti-inflammatory response in liver tissue.

Abstract
Rhodiola imbricata is a perennial herb of the family Crassulaceae, which has significant traditional usage as medicine and is also known to biosynthesize phytochemicals such as flavonoids, coumarins and phenyl glycosides. The present investigation was aimed to estimate the hepatoprotective activity of R. imbricata rhizome acetone extract against paracetamol (2 g/kg) induced liver toxicity. Paracetamol was administered to induce hepatic damage in Wistar rats. 200 and 400 mg/kg doses of rhizome acetone extract and silymarin (25 mg/kg) were used as treatment groups. The blood samples were analyzed for biochemical markers of hepatic injury and tissue samples were subjected for estimation of liver antioxidants and histopathological studies. Analysis of the extract treated rats (400 mg/kg) showed an elevation of superoxide dismutase (0.326 units/min/mg protein), catalase (185.03 μmole of H2O2 consumed/min/mg protein), glutothione peroxidase (19.26 mg GSH consumed/min/mg protein) and reduced glutathione (16.2 μmole of GSH/mg protein). Moreover, the biochemical parameters in serum like alkaline phosphatase, serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and lipid profiles were also improved in treated groups compared to the control. The oral administration of different doses of rhizome acetone extract significantly protected the hepatic cells from damage. The hematological and biochemical parameters were also normal in extract treated rats compared to the control and standard (silymarin) groups. The HPLC analysis revealed the presence of some important phenolic compounds which could be responsible for the hepatoprotective activity. This study proved that R. imbricata could be taken as a good natural source of the hepatoprotective agent.

Abstract
Hypertension remains a major health problem worldwide considering the prevalence of morbidity and mortality. Plants remain a reliable source of efficacious and better tolerated drugs and botanicals. This study was designed to investigate the effect of the chemo-profiled hydroethanolic leaf extract of Byrsocarpus coccineus in ethanol- and sucrose-induced hypertension. Groups of rats were treated orally (p.o.) with distilled water (10 ml/kg), ethanol (35%; 3 g/kg), sucrose (5-7%), and B. coccineus (100, 200, and 400 mg/kg), and nifedipine together with ethanol and sucrose separately for 8 weeks. At the end of the treatment period, blood pressure and heart rate of rats were determined. Blood was collected for serum biochemical parameters and lipid profile assessment, and the liver, aorta, kidney, and heart were harvested for estimation of in vivo antioxidants and malondialdehyde (MDA). Results obtained in this study showed that B. coccineus at the various doses administered reduced the systolic, diastolic, and arterial blood pressure elevated by ethanol and sucrose. Also, the extract reversed the reduction in catalase (CAT), reduced glutathione (GSH), glutathione peroxidase (GPx), and superoxide dismutase (SOD) induced by ethanol and sucrose. The level of MDA was reduced compared to the ethanol- and sucrose-induced hypertensive group. With respect to lipid profile, administration of B. coccineus at the various doses reduced the levels of triglycerides, low-density lipoprotein (LDL), cholesterol, and atherogenic indices, compared to the ethanol and sucrose groups. In conclusion the hydroethanolic leaf extract of B. coccineus exerted significant antihypertensive effect and this is probably related to the antioxidant property and improvement of lipid profile observed in this study.

Abstract
OBJECTIVES The aim of this study was to evaluate the flavonoid content of an ethanolic leaf extract from the medicinal plant Rourea induta Planch. (RIEE) and to investigate its hepatoprotective potential and in vivo antioxidant effects. METHODS Using samples from carbon tetrachloride-treated Wistar female rats treated orally with or without RIEE, we evaluated the aspartate aminotransferase, alanine aminotransferase, and total bilirubin levels in plasma; the levels of the hepatic oxidative stress markers catalase, superoxide dismutase, glutathione peroxidase, and reduced glutathione in liver homogenates; and the thiobarbituric acid reactive substance levels. A histopathology study was performed. A quantitative analysis of the RIEE extract was performed using high-performance liquid chromatography to evaluate its flavonoid content. RESULTS Oral administration of RIEE significantly reduced carbon tetrachloride-induced elevations in the levels of plasma markers of hepatic damage and lipid peroxidation. It also rescued histopathologic alterations observed in the liver and levels of oxidative stress markers. CONCLUSIONS RIEE exhibits antioxidant and hepatoprotective activities in vivo, which may be attributable to its flavonoids composition [hyperin (2), quercetin-3-O-β-xyloside (4), quercetin-3-O-α-arabinofuranoside (5), and quercetin (6)].

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tecomella undulata (TU;` Family Bignoniaceae) is used in Indian Ayurvedic system of medicine for treating various diseases including hepatic ailments. It is also incorporated in various marketed hepatoprotective polyherbal formulations. AIM The present study was aimed at evaluating possible hepatoprotective role of isolated compounds from TU stem bark (TSB) using in vitro and in vivo experimental models. METHODS In vitro cytotoxicity and hepatoprotective potential of various extract, fractions and isolated compounds from TU stem bark were evaluated using HepG2 cells. Rats were pre-treated with TU methanolic extract (TSB-7) or betulinic acid (MS-2) or silymarin for 7 days followed by a single dose of CCl(4) (0.5 ml/kg, i.p.). Plasma markers of hepatic damage, hepatic antioxidants and indices of lipid peroxidation along with microscopic evaluation of liver were assessed in control and treatment groups. RESULTS TSB-2 and MS-1 accounted for significant cell death whereas; TSB-1, TBS-7, TSB-9, TSB-10 and, MS-2 did not register significant cytotoxicity. Further, non-cytotoxic components exhibited ascending grade of hepatoprotection in vitro (TSB-10<TSB-1<TSB-7<TSB-9<MS-2). Pre-treatment of TSB-7 or MS-2 to CCl(4) treated rats prevented hepatocyte damage as evidenced by biochemical and histopathological observations. CONCLUSION It can be concluded that, hepatoprotective potential of Tecomella undulata stem bark is partially due to the presence of betulinic acid.

Abstract
CONTEXT Cnestis ferruginea (CF) Vahl ex DC (Connaraceae) is a shrub abundant in West Africa. Root preparations are used in traditional medicine to treat diverse conditions. OBJECTIVE To evaluate the sub-chronic toxicological effects of the methanol root extract of CF. MATERIALS AND METHODS Groups of adult rats of both sexes were treated daily with distilled water (DW) and CF at doses of 80 (sub-therapeutic dose), 400 (therapeutic dose), and 1000 (supra-therapeutic dose) mg/kg orally for 90 days. Animals were weighed weekly and observed for behavioral and morphological changes. At the end, rats were sacrificed and blood samples collected for hematological and biochemical analysis. Vital organs were harvested, weighed, and assessed for in vivo antioxidants and histopathological changes. Sperm analysis and reversibility study were done, and mortality was recorded. RESULTS CF at the therapeutic dose did not produce any significant irreversible deleterious effects on the weight of animals and vital organs, in vivo antioxidants, histopathological presentation, hematological, biochemical, and sperm parameters. Platelet anomaly was elicited as a delayed effect. Effects at the sub- and supra-therapeutic doses were similar but with delayed anemia in females and weight reduction and sterility in males as possible side effects. CF generally showed a potential to induce in vivo antioxidants. DISCUSSION AND CONCLUSION Findings suggest that CF given over an extended period possess the potential to cause induction of in vivo antioxidants especially in the ovary. Possible side effects identified with CF, which necessitate caution, include delayed platelet anomaly and anemia in females, weight reduction, and sterility in males.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The roots of Hibiscus vitifolius Linn. (Malvaceae) is used for the treatment of jaundice in the folklore system of medicine in India. This study is an attempt to evaluate the hepatoprotective activity of the roots of Hibiscus vitifolius against anti-tubercular drug induced hepatotoxicity. MATERIALS AND METHODS Hepatotoxicity was induced in albino rats of either sex by oral administration of a combination of three anti-tubercular drugs. Petroleum ether, chloroform, methanol and aqueous extracts of roots of Hibiscus vitifolius (400mg/kg/day) were evaluated for their possible hepatoprotective potential. RESULTS All the extracts were found to be safe up to a dose of 2000mg/kg. Among the four extracts studied, oral administration of methanol extract of Hibiscus vitifolius at 400mg/kg showed significant difference in all the parameters when compared to control. There was a significant (P<0.001) reduction in the levels of serum aspartate amino transaminase, alanine amino transferase, alkaline phosphatase, lactate dehydrogenase, total and direct bilirubin, where as an increase was found in the levels of total cholesterol, total protein and albumin. Liver homogenate studies showed a significant increase in the levels of total protein, phospholipids and glycogen, and a reduction in the levels of total lipids, triglycerides, and cholesterol against control animals. In the tissue anti-oxidant studies, we found a significant increase in the levels of catalase and superoxide dismutase, whereas there was marked reduction in the levels of thiobarbituric acid reactive substances, as compared to control. Histology of liver sections of the animals treated with the extracts showed significant reduction of necrosis and fatty formation when compared with control specimens. CONCLUSION These findings suggest that the root extracts of Hibiscus vitifolius have potent hepatoprotective activity, thereby justifying its ethnopharmacological claim.

Abstract
Abstract
Objectives
The leaf decoctions of Tamarindus indica (TI) have long been traditionally used in liver ailments. The aim of this study was to investigate the anti-apoptotic activity of TI leaf extract against acute ethanol (EtOH)-induced liver injury. The major constituents of the extract were also examined for standardization purposes.
Methods
Rats (n = 5–7) were orally pretreated with TI leaf extract (25, 50 and 100 mg/kg) for seven days. Silymarin was used as a positive control. Liver tissue biochemical assays included key markers of apoptosis and its redox signalling. Serum enzyme levels were also determined.
Key findings
All graded doses of TI leaf extract mitigated the EtOH-induced liver caspase-3 activation (42, 57 and 64%) as well as DNA fragmentation (32, 47 and 50%), respectively. The highest dose of the extract demonstrated membrane-stabilizing (38%) in addition to glutathione-replenishing (88%) effects. Also, the leaves improved the liver histopathological alterations. Moreover, major plant bioactive polyphenolics, that might be responsible for the extract's observed effects, were isolated and identified.
Conclusions
TI leaf extract demonstrated promising anti-apoptotic hepatoprotective effects in rats. The use of TI leaves in different liver diseases, having apoptosis as the underlying pathology, hence warrants further clinical investigation.

Abstract
The aim of this study was to investigate the protective ability of blackberry extract (BE) against oxidative stress in carbon tetrachloride (CCl(4))-treated rats. The results showed that treatment with BE attenuated lipid peroxidation that was increased by CCl(4) and also markedly recovered the activity of antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR), that were decreased by CCl(4). BE also elevated the protein expression levels of NF-E2-related factor-2 (Nrf2), CuZnSOD, MnSOD, GPx-1/2, and heme oxygenase-1 (HO-1), but not that of catalase. Furthermore, the administration of BE significantly attenuated the levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) that were increased by CCl(4). Therefore, the present study suggests that BE possesses significant protective effects against in vivo oxidative stress.

Abstract
CONTEXT Liver disease is a serious ailment and the scenario is worsened by the lack of precise therapeutic regimens. Currently available therapies for liver ailments are not apposite and systemic toxicity inhibits their long term use. Medicinal plants have been traditionally used for treating liver diseases since centuries as the toxicity factor appears to be on the lower side. OBJECTIVE Several phytochemials have been identified which have significant hepatoprotective activity with minimal systemic adverse effects which could limit their long term use. The scenario calls for extensive investigations which can lead to development of lead molecules for hepatoprotective molecules of future. This review deals with the biological activity, mode of action and toxicity and forthcoming application of some of these leads. METHODS These generally have strong antioxidative potential and cause induction of antioxidant enzymes like superoxide dismutase, reduced glutathione and catalase. Additional mechanisms of hepatoprotection include stimulation of heme oxygenase-1 activity, inhibition of nitric oxide production, hepatocyte apoptosis and nuclear factor-κB activation. RESULTS AND CONCLUSION Out of the several leads obtained from plant sources as potential hepatoprotective agents, silymarin, andrographolide, neoandrographolide, curcumin, picroside, kutkoside, phyllanthin, hypophyllanthin, and glycyrrhizin have been established as potent hepatoprotective agents. The hepatoprotective potential of several herbal medicines has been clinically evaluated. Significant efficacy has been seen with silymarin, glycyrrhizin and Liv-52 in treatment of hepatitis, alcoholic liver disease and liver cirrhosis.
