Abstract
Alcoholism is a widespread and damaging behaviour of people throughout the world. Long-term alcohol consumption has resulted in alcoholic liver disease (ALD) being the leading cause of chronic liver disease. Many metabolic enzymes, including alcohol dehydrogenases such as ADH, CYP2E1, and CATacetaldehyde dehydrogenases ALDHsand nonoxidative metabolizing enzymes such as SULT, UGT, and FAEES, are involved in the metabolism of ethanol, the main component in alcoholic beverages. Ethanol consumption changes the functional or expression profiles of various regulatory factors, such as kinases, transcription factors, and microRNAs. Therefore, the underlying mechanisms of ALD are complex, involving inflammation, mitochondrial damage, endoplasmic reticulum stress, nitrification, and oxidative stress. Moreover, recent evidence has demonstrated that the gut-liver axis plays a critical role in ALD pathogenesis. For example, ethanol damages the intestinal barrier, resulting in the release of endotoxins and alterations in intestinal flora content and bile acid metabolism. However, ALD therapies show low effectiveness. Therefore, this review summarizes ethanol metabolism pathways and highly influential pathogenic mechanisms and regulatory factors involved in ALD pathology with the aim of new therapeutic insights.

Cajanus cajan ameliorated CCl 4-induced oxidative stress in Wistar rats via the combined mechanisms of anti-inflammation and mitochondrial-membrane transition pore inhibition. JOURNAL OF ETHNOPHARMACOLOGY 2022; 289:114920. [PMID: 35032580 DOI: 10.1016/j.jep.2021.114920] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 12/07/2021] [Accepted: 12/13/2021] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Liver diseases is a public health issue in sub-saharan Africa and has been reported to be the major cause of many hospital admissions. Oxidative stress, mitochondrial dysfunction and inflammation play important roles in several diseases including liver injury. Cajanus cajan is an indigenous medicinal plant useful in the traditional treatment of jaundice, inflammation and liver injury. AIM OF STUDY This study assessed the effects of methanol extract Cajanus cajan (MECC) on mitochondrial permeability transition (mPT) pore opening, biomarkers of oxidative stress and inflammation in CCl4-induced liver injury in rats. METHODS Wistar albino rats (200-210g) were completely randomized into five (5) groups of six animals each. Group I (control) was given distilled water orally once daily. Animals in group II were administered CCl4 in parafin (1:1) at a dose of 0.5 mL/kg i.p on the seventh day. Animals in groups III, IV and V were administered methanol extract of Cajanus cajan (MECC) at doses of 100, 200 mg/kg and silymarin (100 mg/kg) respectively for 7 days prior to a single intraperitoneal dose of CCl4. After 24 h of CCl4 treatment, serum and liver tissues were collected. Mitochondrial permeability transition (mPT) pore opening, mitochondrial ATPase activities and biomarkers of oxidative stress were determined spectrophotometrically. Tumor necrosis factor (TNFα), NF-κB and COX-2 were determined by immunohistochemistry and the phytochemicals present in the extract were determined by GC-MS. RESULTS Liver enzyme (AST, ALP, ALT and γGT) activities and MDA levels were significantly decreased in rats pretreated with MECC at the dose of 100, 200 and silymarin (100 mg/kg) when compared to the rats administered CCl4 alone (p < 0.05). GSH, GST, CAT and SOD increased and the expressions of TNFα, NF-κB and COX- 2 were also reduced when compared to the CCl4- treated animals. In addition, the liver histopathological analyses revealed that MECC markedly alleviated inflammatory cell infiltration, hepatic fibrosis, hepatocyte ballooning, necrosis and severe apoptosis of hepatocytes induced by CCl4. GC-MS analysis yielded 23 compounds including flavonoids, terpenoids and fatty acids. CONCLUSION Cajanus cajan leaf extract elicited hepatoprotective action on CCl4-induced liver injury via inhibition of mPT pore opening, prevention of CCl4-induced hepatic oxidative stress and suppression of inflammatory response thus it may become useful for chemoprevention of liver injury. This supports its traditional use.

Abstract
Liver diseases are quite prevalant in many densely populated countries, including Bangladesh. The liver and its hepatocytes are targeted by virus and microbes, as well as by chemical environmental toxicants, causing wide-spread disruption of metabolic fuctions of the human body, leading to death from end-stage liver diseases. The aim of this review is to systematically explore and record the potential of Bangladeshi ethnopharmacological plants to treat liver diseases with focus on their sources, constituents, and therapeutic uses, including mechanisms of actions (MoA). A literature survey was carried out using Pubmed, Google Scholar, ScienceDirect, and Scopus databases with articles reported until July, 2020. A total of 88 Bangladeshi hepatoprotective plants (BHPs) belonging to 47 families were listed in this review, including Euphorbiaceae, Cucurbitaceae, and Compositae families contained 20% of plants, while herbs were the most cited (51%) and leaves were the most consumed parts (23%) as surveyed. The effect of BHPs against different hepatotoxins was observed via upregulation of antioxidant systems and inhibition of lipid peroxidation which subsequently reduced the elevated liver biomarkers. Different active constituents, including phenolics, curcuminoids, cucurbitanes, terpenoids, fatty acids, carotenoids, and polysaccharides, have been reported from these plants. The hepatoameliorative effect of these constituents was mainly involved in the reduction of hepatic oxidative stress and inflammation through activation of Nrf2/HO-1 and inhibition of NF-κB signaling pathways. In summary, BHPs represent a valuable resource for hepatoprotective lead therapeutics which may offer new alternatives to treat liver diseases.

Abstract
ABSTRACT Eupatilin is known to possess anti-apoptotic, anti-oxidative, and anti-inflammatory properties. We report here that eupatilin has a protective effect on the ethanol-induced injury in rats. Sprague–Dawley rats were divided into 6 groups: control, vehicle, silymarin, eupatilin 10 mg/kg, eupatilin 30 mg/kg, and eupatilin 100 mg/kg. Plasma levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were analyzed to determine the extent of liver damage. Total cholesterol (TC) and triglycerides (TG) were analyzed to determine the level of liver steatosis. Malondialdehyde level, superoxide dismutase (SOD) activity, and glutathione (GSH) level were analyzed to determine the extent of oxidative stress. Tumor necrosis factor (TNF)-α and interleukin (IL)-1β were quantified to verify the degree of inflammation. Based on our findings, chronic alcohol treatment significantly changed the serum indexes and liver indicators of the model rats, which were significantly improved by eupatilin treatment. Rats in the eupatilin-treatment group showed reduced levels of AST, ALT, TG, TC, TNF-α, and IL-1β, increased SOD activity and GSH levels, and improved overall physiology compared to the alcoholic liver disease model rats. H&E staining also verified the eupatilin-mediated improvement in liver injury. In conclusion, eupatilin inhibits alcohol-induced liver injury via its antioxidant and anti-inflammatory effects.

Abstract
Excessive alcohol consumption induces acute intoxication and various hepatic diseases. In this study, we investigated the effect of the CureZyme-ACE (CA), Acetobacter Pasteurianus (AP)-derived product, in acute intoxication rats. The ethanol and acetaldehyde levels of serum were lower in rats treated with CA than those who only treated ethanol. The activities of alcohol dehydrogenase and acetaldehyde dehydrogenase also recovered faster in the CA group than only-ethanol group. The transaminase levels (AST, ALT) in the CA group were significantly lower than only-ethanol group. In addition, Hepatic histological analyses and stomach wall were demonstrated that the CA-treated group recovered faster than only-ethanol group. With regard to most characteristics, we found that CA had dose-dependent effects. At high concentrations of CA, there were no differences in the tested parameters compared to those of normal rats. These findings indicate that CA reduces the serum alcohol concentration and some of the hepatic damage caused by alcohol intoxication.

Abstract
Background The plant Cajanus cajan had earlier shown protective effect against hypoxic-ischemic brain damage in rats. Objective Hence, hydroalcoholic extract of C. cajan Linn leaves (HECC) was evaluated for its protective role against memory impairment in sleep-deprived Sprague Dawley rats. Materials and methods Adult rats were divided into five groups each consisting of 5 rats (n = 5). Groups I, II, III, IV and V received 1 mL/kg 1% CMC, 1 mL/kg 1% CMC, 200 mg/kg HECC, 400 mg/kg HECC and 200 mg/kg piracetam respectively as per b.wt. orally everyday for 14 days. Animals of every groups except group-I were subjected to sleep-deprivation from 15th to 19th day for induction of memory impairment. Behavioral activities i.e., elevated plus maze test and locomotor activity were evaluated. Afterwards, brain was isolated from the sacrificed animals for biochemical investigation of acetylcholinesterase (AChE); antioxidant activities i.e., catalase (CAT), superoxide dismutase (SOD), lipid peroxide; and histopathological changes. Results The percent number of entries, number of entries in open arm, AChE activity, lipid peroxide activity of HECC-treated group-III and group-IV were significantly (p < 0.01) decreased while, their CAT and SOD activities were significantly (p < 0.01) increased in dose-dependent manner as compared to sleep-deprived group-II. The activities of group-IV were almost significantly equivalent to that of piracetam-treated group-V. Protective effect of HECC was well supported with brain's histopathology. Conclusion HECC possesses a protective effect against memory impairment indicating its therapeutic efficacy against memory loss as in Alzheimer's disease. Probable underlying mechanisms may be brain's AChE inhibition and increased antioxidant potential by HECC.

Abstract
Carlinoside is a unique compound well-known for its excellent curative potential in hepatitis. There is a substantial research gap regarding the medicinal use of carlinoside, as its concentrations are greatly variable (depending on locality). We cultivated Cajanus cajan using vermicompost as a major organic amendment at two locations (Sonitpur and Birbhum) with different soil types, but identical climate conditions. Sonitpur soils were richer in soil organic C (SOC), enzyme activation, and N/P content than Birbhum. However, vermi-treatment improved many soil properties (bulk density, water retention, pH, N/P/K, and enzyme activity) to narrow the locational gap in soil quality by 15-28%. We also recorded a many-fold increment in SOC storage capacities in both locations, which was significantly correlated with carlinoside, total phenol, and flavonoid contents in Cajanus leaves. This significantly up-regulated the carlinoside induced expression of the bilirubin-solubilizing UGT1A1enzyme in HepG2 cell and rat liver. Leaf extracts of vermicompost-aided plants could cure hepatitis in affected rat livers and in the HepG2 cell line. Accordingly, vermi-treatment is an effective route for the growth of Cajanus as a cash crop for biomedical applications and can produce a concurrent improvement in soil quality.

Abstract
The liver disease related to chronic alcohol consumption is one of the leading causes of death for alcoholics. The efficient drug to ameliorate the alcoholic liver injury was needed urgently. The present study was performed to investigate whether artemisinin possessed the protective effect against chronic alcohol consumption. 50 male Kunming mice were divided into 5 groups: control group (C): 10ml/kg saline+10ml/kg saline, alcohol group (A): 10ml/kg 56%(v/v) alcohol+10ml/kg saline, low dose group of artemisinin (L): 10ml/kg 56%(v/v) alcohol+30mg/kg/day artemisinin, medium dose group of artemisinin (M): 10ml/kg 56%(v/v) alcohol+60mg/kg/day artemisinin, high dose group of artemisinin (H): 10ml/kg 56%(v/v) alcohol+120mg/kg/day artemisinin. Drugs were given orally every day. The general state of mice was observed and the levels of serum activities of AST and ALT were detected after treatment with drugs for 30days. Besides, the liver weight index was calculated and histopathological analysis was performed. We successfully demonstrated that treatment with high dose of artemisinin significantly decreased the elevated levels of AST (p<0.05) and ALT (p<0.01) in plasma, as well as the liver weight index (p<0.01). The loss of body weight, tissue injury, oedema and inflammatory cell infiltration in the hepatocytes were found in the A group. These symptoms were remarkably alleviated in animals treated with artemisinin. Artemisinin can inhibit the activation of NF-кB and the expression of inflammatory cytokines inducible nitric oxide synthase. Besides, it can also enhance the stability of liver cell membrane, and reduce the damage of liver cell membrane and liver cell. Artemisinin showed a protective effect against chronic alcohol poisoning and it has a great potential for the clinical application to treat the liver injury induced by alcohol.

Abstract
BACKGROUND Pigeon pea (Cajanus cajan) leaves are a good source of nutrition and health benefitting phenolic compounds. However, its importance has not yet been effectively addressed. Recently, a 2-year field experiment was attempted in an alluvial soil to understand the role of various organic and inorganic fertilisers and their combinations not only on soil quality, but also on production of foremost phenolic compounds and imparting antioxidant and antibacterial properties in C. cajan under vermicompost treatments. RESULTS Notable enhancements in crude protein, soluble carbohydrate, ash content and total flavonoid content were recorded in Cajanus leaves under vermicompost treatments. We detected a significant rise in carlinoside content in C. cajan leaves, which is known to reduce bilirubin concentration in hepatitis affected human blood. Farmyard manure treatments resulted in a high crude fibre content coupled with a substantially high concentration of total phenols, and chlorophyll. In addition, incorporation of vermicompost with or without inorganic fertiliser in the soil had a significant impact on antioxidant and antibacterial properties of C. cajan leaves. Above and beyond, farmyard manure and vermicompost positively influenced the physico-chemical health of the soil. CONCLUSION The present nutrient management scheme based on organic input not only induced a higher yield of C. cajan endowed with improved antioxidant and antibacterial properties, but also enhanced the production of various phenolic compounds. © 2016 Society of Chemical Industry.

Abstract
BACKGROUND The antioxidant capacity and hypolipidaemic effects of Vigna unguiculata, as well as their potential improvement by different fermentation and thermal processes were studied using in vitro and in vivo methods. RESULTS Phenolic content and reducing capacity of legume acetone extract were significantly increased by different fermentation processes, and by the thermal treatment of fermented legume flours. TBARS inhibiting capacity was increased by fermentation but not by thermal treatment. A higher ability to decrease Cu(2+)/H2O2-induced electrophoretic mobility of LDL was found in fermented when compared to raw legume extracts, and a higher protective effect on short term metabolic status of HT-29 cells was found for raw and lactobacillus-fermented Vigna followed by naturally fermented Vigna extracts. Significant improvements in plasma antioxidant capacity and hepatic activity of antioxidant enzymes were observed in rats that consumed fermented legume flours when compared to the untreated legume or a casein-methionine control diet. In addition, liver weight and plasma levels of cholesterol and triglycerides were also positively affected by untreated or naturally fermented Vigna. CONCLUSION V. unguiculata has demonstrated its potential as a functional food with interesting antioxidant and lipid lowering properties, which can be further augmented by fermentation processes associated or not to thermal processing.

In vitro antihelmintic effect of fifteen tropical plant extracts on excysted flukes of Fasciola hepatica. BMC Vet Res 2015; 11:45. [PMID: 25890066 PMCID: PMC4357144 DOI: 10.1186/s12917-015-0362-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2014] [Accepted: 02/19/2015] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Fasciolosis due to Fasciola hepatica is the most important hepatic disease in veterinary medicine. Its relevance is important because of the major economical losses to the cattle industry such as: reduction in milk, meat and wool production; miscarriages, anemia, liver condemnation and occasionally deaths, are estimated in billons of dollars. The emergence of fluke resistance due to over or under dosing of fasciolides as well as environmental damage produced by the chemicals eliminated in field have stimulated the need for alternative methods to control Fasciola hepatica. The aim of this study was to evaluate the in vitro anthelmintic effect of fifteen tropical plant extracts used in tradicional Mexican medicine, on newly excysted flukes of Fasciola hepatica. RESULTS The flukes were exposed in triplicate at 500, 250 and 125 mg/L to each extract. The efficacy was assessed as the mortality rate based on the number of live and dead flukes after 24, 48 and 72 h post-exposure. The plants with anthelmintic effect were evaluated once again with a concentration of 375 mg/L in order to confirm the results and to calculate lethal concentrations at 50%, 90% and 99% (LC(50), LC(90), and LC(99)). Plant extracts of Lantana camara, Bocconia frutescens, Piper auritum, Artemisia mexicana and Cajanus cajan had an in vitro anthelmintic effect (P <0.05). The LC(50), LC(90) and LC(99) to A. mexicana, C. cajan and B. frutescens were 92.85, 210.44 and 410.04 mg/L, 382.73, 570.09 and 788.9 mg/L and 369.96, 529.94 and 710.34 mg/L, respectively. CONCLUSION It is concluded that five tropical plant extracts had promising anthelmintic effects against F. hepatica. Further studies on toxicity and in vivo biological evaluation in ruminant models might help to determine the anthelmintic potential of these plant extracts.

Abstract
Many Chinese medicines have the potential to be hepatoprotective and therefore can be used to treat acute and chronic liver diseases. The challenge is to identify the molecular target for their protective mechanism. This study investigated the induction of nuclear factor-erythroid 2(NF-E2)-related factor 2 (Nrf2) antioxidant genes and metallothionein as a common mechanism of hepatoprotective effects of Chinese medicines such as Piper puberulum. Mice were pretreated with Piper puberulum extract (PPE, 500 mg/kg, po) or vehicles for seven days, followed by intoxication with CCl 4 (25 μl/kg, ip for 16 h), D-galactosamine (800 mg/kg, ip for 8 h), or acetaminophen (400 mg/kg, ip for 8 h). Hepatotoprotection was evaluated by serum enzyme activities and histopathology. To determine the mechanism of protection, mice were given PPE (250-1000 mg/kg, po for seven days) and livers were collected to quantify the expression of Nrf2-targeted genes and metallothionein. Nrf2-null mice were also used to determine the role of Nrf2 in PPE-mediated hepatoprotection.PPE pretreatment protected against the hepatotoxicity produced by CCl 4, D-galactosamine, and acetaminophen, as evidenced by decreased serum enzyme activities and ameliorated liver lesions. PPE treatment increased the expression of hepatic Nrf2, NAD(P)H:quinone oxidoreductase1 (Nqo1), heme oxygenase-1 (Ho-1), glutamate-cysteine ligases (Gclc), and metallothionein (MT), at both transcripts and protein levels. PPE protected wild-type mice from CCl 4 and acetaminophen hepatotoxicity, but not Nrf2-null mice, fortifying the Nrf2-dependent protection. In conclusion, induction of the Nrf2 antioxidant pathways and metallothionein appears to be a common mechanism for hepatoprotective herbs such as PPE.

Abstract
BACKGROUND Oxidative stress not only develops complications in diabetic (type 1 and type 2) but also contributes to beta cell destruction in type 2 diabetes in insulin resistance hyperglycemia. Glucose control plays an important role in the pro-oxidant/antioxidant balance. Some antidiabetic agents may by themselves have antioxidant properties independently of their role on glucose control. OBJECTIVE The present investigation draws a comparison of the protective antioxidant activity, total phenol content and the antihyperglycemic activity of the methanolic extract of Cajanus cajan root (MCC) and Tamarindus indica seeds (MTI). MATERIALS AND METHODS Antidiabetic potentials of the plant extracts were evaluated in alloxan-induced diabetic Swiss albino mice. The plant extracts at the doses of 200 and 400 mg/kg body weight was orally administered for glucose tolerance test during 1-hour study and hypoglycemic effect during 5-day study period in comparison with reference drug Metformin HCl (50 mg/kg). In vitro antioxidant potential of MCC and MTI was investigated by using 1, 1- diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity at 517 nm. Total phenolic content, total antioxidant capacity and reducing power activity was also assayed. RESULTS There was a significant decrease in fasting serum glucose level (P < 0.001), reduction in blood glucose level (P < 0.001) in 5-days study, observed in the alloxan-induced diabetic mice. The reduction efficacy of blood glucose level of both the extracts is proportional to their dose but MCC is more potent than MTI. Antioxidant study and quantification of phenolic compound of both the extracts revealed that they have high antioxidant capacity. CONCLUSION These studies showed that MCC and MTI have both hypoglycemic and antioxidant potential but MCC is more potent than MTI. The present study suggests that both MCC and MTI could be used in managing oxidative stress.

Abstract
Alcohol is a severe hepatotoxicant that causes liver abnormalities such as steatosis, cirrhosis, and hepatocarcinoma. Crepidiastrum denticulatum (CD) is a well-known, traditionally consumed vegetable in Korea, which was recently reported to have bioactive compounds with detoxification and antioxidant properties. In this study, we report the hepatoprotective effect of CD extract against chronic alcohol-induced liver damage in vivo. The rats that were given CD extract exhibited decreased alanine aminotransferase, aspartate aminotransferase, and γ-glutamyl transpeptidase activities, which are liver damage markers that are typically elevated by alcohol consumption. The results were confirmed by histopathology with hematoxylin and eosin staining. Chronic alcohol consumption induced the formation of alcoholic fatty liver. However, treatment with CD extract dramatically decreased the hepatic lipid droplets. Treatment with CD extract also restored the antioxidative capacity and lipid peroxidation of the liver that had been changed by alcohol consumption. Furthermore, treatment with CD extract normalized the activities of the antioxidative enzymes superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase, which had been decreased by alcohol consumption. The results indicate that CD extract has protective effects against chronic alcohol hepatotoxicity in rats by increasing the liver's antioxidant capacity, and has potential as a dietary supplement intervention for patients with alcohol-induced liver damage.

Abstract
This study aims to evaluate two proteins derived from the seeds of the plants Cajanus cajan (Leguminosae) and Caesalpinia gilliesii (Leguminosae) for their abilities to ameliorate the toxic effects of chronic doses of acetoaminphen (APAP) through the determination of certain biochemical parameters including liver marker enzymes: alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and total bilirubin. Also, total protein content and hepatic marker enzyme, lactate dehydrogenase were studied. Moreover, liver antioxidants, glutathione (GSH), nitric oxide, and lipid peroxides were determined in this study. Hepatic adenosine triphosphatase (ATPase), adenylate energy charge (ATP, adenosine diphosphate, adenosine monophosphate, and inorganic phosphate), and phosphate potential, serum interleukin-6, tumor necrosis factor-α, and myeloperoxidase were also examined in the present study. On the other hand, histopathological examination of intoxicated and liver treated with both proteins was taken into consideration. The present results show disturbances in all biochemical parameters and hepatic toxicity signs including mild vascular congestion, moderate inflammatory changes with moderate congested sinusoids, moderate nuclear changes (pyknosis), moderate centrilobular necrosis, fatty changes, nuclear pyknosis vascular congestion, and change in fatty centrilobular necrosis liver. Improvement in all biochemical parameters studied was noticed as a result of treatment intoxicated liver with C. gilliesii and C. cajan proteins either paracetamol with or post paracetamol treatment. These results were documented by the amelioration signs in rat's hepatic architecture. Thus, both plant protein extracts can upregulate and counteract the inflammatory process, minimize damage of the liver, delay disease progression, and reduce its complications.

Abstract
The present work aims to evaluate the protective and ameliorative effects of two plant-derived proteins obtained from the seeds of Cajanus cajan and Caesalpinia gilliesii(Leguminosae) against the toxic effects of acetaminophen in kidney after chronic dose through determination of certain biochemical markers including total urea, creatinine, and kidney marker enzyme, that is, glyceraldehyde-3-phosphate dehydrogenase (GAPDH). In addition histopathological examination of intoxicated and treated kidney with both proteins was performed. The present results show a significant increase in serum total urea and creatinine, while significant decrease in GAPDH. Improvement in all biochemical parameters studied was demonstrated, which was documented by the amelioration signs in rats kidney architecture. Thus, both plant protein extracts can counteract the nephrotoxic process, minimize damage to the kidney, delay disease progression, and reduce its complications.

Abstract
Alcohol consumption is frequently associated with various cancers and the enhancement of the metabolic activation of carcinogens has been proposed as a mechanism underlying this relationship. The ethanol-induced enhancement of N-nitrosodiethylamine (DEN)-mediated carcinogenesis can be attributed to an increase in hepatic activity. However, the mechanism of elevation of N-nitrosomethylbenzylamine (NMBA)-induced tumorigenesis remains unclear. To elucidate the mechanism underlying the role of ethanol in the enhancement of NMBA-induced oesophageal carcinogenesis, we evaluated the hepatic and extrahepatic levels of the cytochrome P450 (CYP) and mutagenic activation of environmental carcinogens by immunoblot analyses and Ames preincubation test, respectively, in F344 rats treated with ethanol. Five weeks of treatment with 10% ethanol added to the drinking water or two intragastric treatments with 50% ethanol, both resulted in elevated levels of CYP2E1 (1.5- to 2.3-fold) and mutagenic activities of DEN, N-nitrosodimethylamine and N-nitrosopyrrolidine in the presence of rat liver S9 (1.5- to 2.4-fold). This was not the case with CYP1A1/2, CYP2A1/2, CYP2B1/2 or CYP3A2, nor with the activities of 2-amino-3-methylimidazo[4,5-f]quinoline, 3-amino-1-methyl-5H-pyrido[4,3-b]indole, aflatoxin B(1) or other N-nitroso compounds (NOCs), including NMBA. Ethanol-induced elevations of CYP2A and CYP2E1 were observed in the oesophagus (up to 1.7- and 2.3-fold) and kidney (up to 1.5- and 1.8-fold), but not in the lung or colon. In oesophagus and kidney, the mutagenic activities of NMBA and four NOCs were markedly increased (1.3- to 2.4-fold) in treated rats. The application of several CYP inhibitors revealed that CYP2A were likely to contribute to the enhancing effect of ethanol on NMBA activation in the rat oesophagus and kidney, but that CYP2E1 failed to do so. These results showed that the enhancing effect of ethanol on NMBA-induced oesophageal carcinogenesis could be attributed to an increase in the metabolic activation of NMBA by oesophageal CYP2A during the initiation phase, and that this occurred independently of CYP2E1.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Long-term excess alcohol exposure leads to alcoholic liver disease (ALD)-a global health problem without effective therapeutic approach. ALD is increasingly considered as a complex and multifaceted pathological process, involving oxidative stress, inflammation and excessive fatty acid synthesis. Over the past decade, herbal medicines have attracted much attention as potential therapeutic agents in the prevention and treatment of ALD, due to their multiple targets and less toxic side effects. Several herbs, such as Cnidium monnieri (L.) Cusson (Apiaceae), Curcuma longa L. (Zingiberaceae) and Pueraria lobata (Willd.) Ohwi (Leguminosae), etc., have been shown to be quite effective and are being widely used in China today for the treatment of ALD when used alone or in combination. AIM OF THE REVIEW To review current available knowledge on herbal medicines used to prevent or treat ALD and their underlying mechanisms. MATERIALS AND METHODS We used the pre-set searching syntax and inclusion criteria to retrieve available published literature from PUBMED and Web of Science databases, all herbal medicines and their active compounds tested on ALD induced by both acute and chronic alcohol ingestion were included. RESULTS A total of 40 experimental studies involving 34 herbal medicines and (or) active compounds were retrieved and reviewed. We found that all reported extracts and individual compounds from herbal medicines/natural plants could be beneficial to ALD, which might be attributed to regulate multiple critical targets involved in the pathways of oxidation, inflammation and lipid metabolism. CONCLUSIONS Screening chemical candidate from herbal medicine might be a promising approach to drug discovery for the prevention or treatment of ALD. However, further studies remain to be done on the systematic assessment of herbal medicines against ALD and the underlying mechanisms, as well as their quality control studies.

Abstract
Wu-Chia-Pi medicated wine, composed nine Chinese medicines soaked in 35% alcohol, is widely used in Asia for its health-promoting functions. However, long-term consumption of alcohol could result in liver dysfunction. In this study, Wu-Chia-Pi solution (WCPS) and extract (WCPE) were prepared by modification of the principals given by the Committee on Chinese Medicine and Pharmacy in Taiwan. The aim of this study was to explore the protective effect of WCPS against carbon tetrachloride (CCl4)-induced liver injury and to clarify its active component(s). Antioxidative effects of the test samples were evaluated via MDA inhibition, catalase activity and DPPH-scavenging assays. HPLC was used to analysis the active components. Results showed that WCPS (1 and 5 mL/kg) significantly prevented CCl4-induced liver injury without chronic liver toxicity. Referring to the antioxidative activities, WCPE displayed significant MDA inhibitory and DPPH-scavenging activities with IC50 values of 0.91 ± 0.03 and 0.60 ± 0.04 mg/mL, respectively. Catalase activity was also enhanced by treatment of WCPE, acteoside and quercetin. Therefore, we suggest that acteoside and quercetin are the major contributors to the antioxidative and hepatoprotective activities of WCPS, and a possible mechanism could be mediated through reduction of oxidative stress.

Abstract
Cajaninstilbene acid (CSA) is a major active component present in the leaves of Cajanus cajan (L.) Millsp. The present study explores the underlying cellular mechanisms for CSA-induced relaxation in rat renal arteries. Vascular reactivity was examined in arterial rings that were suspended in a Multi Myograph System and the expression of signaling proteins was assessed by Western blotting method. CSA (0.1–10 µM) produced relaxations in rings pre-contracted by phenylephrine, serotonin, 9, 11-dideoxy-9α, 11α-epoxymethanoprostaglandin F2α (U46619), and 60 mM KCl. CSA-induced relaxations did not show difference between genders and were unaffected by endothelium denudation, nor by treatment with NG-nitro-L-arginine methyl ester, indomethacin, ICI-182780, tetraethylammonium ion, BaCl2, glibenclamide, 4-aminopyridine or propranolol. CSA reduced contraction induced by CaCl2 (0.01–5 mM) in Ca2+-free 60 mM KCl solution and by 30 nM (−)-Bay K8644 in 15 mM KCl solution. CSA inhibited 60 mM KCl-induced Ca2+ influx in smooth muscle of renal arteries. In addition, CSA inhibited contraction evoked by phorbol 12-myristate 13-acetate (PMA, protein kinase C agonist) in Ca2+-free Krebs solution. Moreover, CSA reduced the U46619- and PMA-induced phosphorylation of myosin light chain (MLC) at Ser19 and myosin phosphatase target subunit 1 (MYPT1) at Thr853 which was associated with vasoconstriction. CSA also lowered the phosphorylation of protein kinase C (PKCδ) at Thr505. In summary, the present results suggest that CSA relaxes renal arteries in vitro via multiple cellular mechanisms involving partial inhibition of calcium entry via nifedipine-sensitive calcium channels, protein kinase C and Rho kinase.

Effect of Emilia sonchifolia (Linn.)DC on alcohol-induced oxidative stress in pancreas of male albino rats. ASIAN PAC J TROP MED 2012; 4:973-7. [PMID: 22118034 DOI: 10.1016/s1995-7645(11)60229-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2011] [Revised: 09/11/2011] [Accepted: 10/15/2011] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE To explore the efficacy of n-hexane extract of Emilia sonchifolia (E. sonchifobia) against ethanol induced pancreatic dysfunction in the young Wistar albino rats. METHODS The rats were divided into four groups. Control rats in group received distilled water orally, group received oral administration of 20% (w/v) ethanol dissolved in drinking water, group received oral administration of 20% (w/v) ethanol in distilled water+n-hexane extract of E. sonchifolia (250 mg/kg body weight), and group received oral administration of n-hexane extract of E. sonchifolia (250 mg/kg body weight) alone. Liver marker enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), pancreatic enzymatic antioxidants superoxide dismutase, lipid peroxidation, catalase, glutathione peroxidase, non-enzymatic antioxidants glutathione and vitamin C were measured and compared. RESULTS Administration of 20% ethanol for 16 weeks significantly increased the liver marker enzymes AST, ALT(P<0.05), reduced the pancreatic enzymatic antioxidants superoxide dismutase, lipid peroxidation, catalase, glutathione peroxidase, glutathione and vitamin C(P<0.05). Histopathological examination showed that the ethanol provoked the oxidative stress which was demonstrated as pancreatic necrosis and oedema. Simultaneous administration of n-hexane extract of E. sonchifolia (250 mg/kg body weight) protected the pancreas against the damage induced by ethanol which was confirmed by the histopathological studies and the normalization of biochemical parameters. CONCLUSIONS Thus n-hexane extract of E. sonchifolia shows a promise in therapeutic use in alcohol induced oxidative stress.

Abstract
CONTEXT Ethnobotanical surveys conducted on Pelargonium reniforme Curtis (Geraniaceae) have shown that the aqueous root extracts are used to treat alcohol-induced liver damage. OBJECTIVE We evaluated the antioxidant properties of the extract and its effects on alcohol-induced hepatotoxicity using Wistar rats. MATERIALS AND METHODS Alcohol-induced hepatotoxicity studies were carried out by observing the effect of the aqueous root extract on some liver marker enzymes, bilirubin, and total protein after liver damage. The levels of some phenolic compounds were determined by standard methods. Also, the reducing power of the plant extract and its ability to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH*) and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS*+) radicals were determined to evaluate its antioxidant activity. RESULTS AND DISCUSSION The results obtained show that the plant extract possessed significant antioxidant activity. It had a significant level of phenolic compounds, scavenged DPPH* and ABTS*+ radicals effectively, and demonstrated good reducing power. This may indicate that the plant contained compounds which can remove toxic metabolites following alcohol abuse. Serum analysis of animals treated with only ethanol showed a significant increase in the levels of liver marker enzymes and total and unconjugated bilirubin, while a significant decrease was observed in the levels of conjugated bilirubin and total proteins. Administration of the plant extract restored the levels of these markers to normal levels, and this indicates the ability of the plant extract to restore normal functioning of a damaged liver. CONCLUSION The study shows that P. reniforme is a potential source of antioxidants and compounds which are useful in treating alcoholic liver damage.

Abstract
The study evaluated the protective effect of anthocyanin-rich extract from black rice (AEBR) on chronic ethanol-induced biochemical changes in male Wistar rats. Administration of ethanol (3.7 g/kg/day) to Wistar rats for 45 days induced liver damage with a significant increase (P < 0.05) of aspartate transaminase (AST), alanine transaminase (ALT), gamma glutamyl transferase (GGT) in the serum and the hepatic malondialdehyde (MDA) level. In contrast, administration of AEBR (500 mg/kg) along with alcohol significantly (P < 0.01) decreased the activities of liver enzymes (AST, ALT and GGT) in serum, the MDA levels and the concentrations of serum and hepatic triglyceride (TG) and total cholesterol (TCH). Rats treated with AEBR showed a better profile of the antioxidant system with normal glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and glutathione S-transferase (GST) activities. All these results were accompanied by histological observations in liver. The results demonstrate that AEBR has a beneficial effect in reducing the adverse effect of alcohol.

Abstract
The essential oils of four plant species from Nigeria have been extracted by hydrodistillation and analyzed by GC and GC-MS. The oils of Cajanus cajan were comprised of sesquiterpenes (92.5%, 81.2% and 94.3% respectively in the leaves, stem and seeds). The major compounds identified were α-himachalene (9.0-11.5%), β-himachalene (8.0-11.0%), γ-himachalene (6.9-8.1%), α-humulene (7.1-8.7%) and α-copaene (4.5-5.6%). However, monoterpenoid compounds (81.8%) dominated the oil of Moringa oleifera with an abundance of α-phellandrene (25.2%) and p-cymene (24.9%). On the other hand, aldehydes (52.8%) occurred in the highest amount in Heliotropium indicum, represented by phenylacetaldehyde (22.2%), ( E)-2-nonenal (8.3%) and (E, Z)-2-nonadienal (6.1%), with a significant quantity of hexahydrofarnesylacetone (8.4%). The leaf and stem oils of Bidens pilosa were dominated by sesquiterpenes (82.3% and 59.3%, respectively). The main compounds in the leaf oil were caryophyllene oxide (37.0%), β-caryophyllene (10.5%) and humulene oxide (6.0%), while the stem oils had an abundance of hexahydrofarnesyl acetone (13.4%), δ-cadinene (12.0%) and caryophyllene oxide (11.0%). The observed chemical patterns differ considerably from previous investigations.

Antioxidant activities of extracts and main components of Pigeonpea [Cajanus cajan (L.) Millsp.] leaves. Molecules 2009; 14:1032-43. [PMID: 19305357 PMCID: PMC6253773 DOI: 10.3390/molecules14031032] [Citation(s) in RCA: 121] [Impact Index Per Article: 8.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2008] [Revised: 01/06/2009] [Accepted: 02/24/2009] [Indexed: 11/20/2022] Open
Abstract
Antioxidant activities of the aqueous and ethanol extracts of pigeonpea [Cajanuscajan (L.) Millsp.] leaves, as well as petroleum ether, ethyl acetate, n-butanol and water fractions and the four main compounds separated from the ethanol extract, i.e. cajaninstilbene acid (3-hydroxy-4-prenylmethoxystilbene-2-carboxylic acid), pinostrobin, vitexin and orientin, were examined by a DPPH radical-scavenging assay and a β-carotene-linoleic acid test. In the DPPH system, the antioxidant activity of the ethanol extracts was superior to that of the aqueous extracts, with IC50 values were 242.01 and 404.91 µg/mL, respectively. Among the four fractions, the ethyl acetate one showed the highest scavenging activity, with an IC50 value of 194.98 µg/mL. Cajaninstilbene acid (302.12 µg/mL) and orientin (316.21 µg/mL) showed more efficient radical-scavenging abilities than pinostrobin and vitexin. In the β-carotene-linoleic acid test, the inhibition ratio (%) of the ethyl acetate fraction (94.13%±3.41%) was found to be the highest, being almost equal to the inhibition capacity of the positive control BHT (93.89%±1.45%) at 4 mg/mL. Pinostrobin (>500 µg/mL) and vitexin (>500 µg/mL) showed insignificant antioxidant activities compared with cajaninstilbene (321.53 µg/mL) and orientin (444.61 µg/mL). In general, the ethyl acetate fraction of the ethanol extract showed greater activity than the main compounds in both systems, such results might be attributed to the synergistic effects of the components. The antioxidant activities of all the tested samples were concentration-dependent. Based on the results obtained, we can conclude that the pigeonpea leaf extracts may be valuable natural antioxidant sources and are potentially applicable in both medicine and the healthy food industry.
