Licorice is commonly used as a cure for digestive disorders and as a detoxification agent in East Asia. This study investigated the protective effect of licorice water extract against cadmium (CdCl2, Cd)-induced liver toxicity in rats. To induce acute toxicity, Cd (4 mg/kg body weight) was dissolved in normal saline and intravenously (i.v.) injected into rats. The rats then received either a vehicle or licorice water extract (50, 100 mg/kg/day) for 3 days, and were subsequently exposed to a single injection of Cd 24 h after the last licorice/vehicle treatment. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) were significantly increased by Cd treatment. In contrast, pretreatment with licorice reduced ALT, AST and LDH. In histopathological analysis, licorice decreased the central necrosis around central veins, the peripheral hemorrhage around portal triads, the percentage of degenerative hepatic regions (%/mm2hepatic parenchyma) and the number of degenerative hepatic cells (N/100 hepatic cells). Licorice also inhibited the increment of Bad (a BH3 domain-containing protein) translocation by Cd in liver cells. These results demonstrate that licorice could have a hepatoprotective effect by inhibiting the translocation of Bad to the mitochondria in Cd-intoxificated rats.

Orthosiphon Stamineus

Orthosiphon stamineus (OS), Benth. (Lamiaceae) is widely used in Malaysia for treatments of various kidney and liver ailments. In the experiment, DPPH• radicals scavenging, Fe 3+-induced lipid peroxidation inhibiting activities and trolox equivalent antioxidant capacity (TEAC) of methanol/water extract of Orthosiphon stamineus (SEOS) were determined. The results indicated that SEOS exhibited antioxidant, lipid peroxidation inhibition and free radical scavenging activities. The hepatoprotective activity of the SEOS was studied using CCl 4-induced liver toxicity in rats. The activity was assessed by monitoring liver function tests through the measurement of alanine transaminase (ALT) and aspartate transaminase (AST). Furthermore, hepatic tissues were also subjected to histopathological studies. Pretreatment of SEOS (125, 250, 500 and 1000 mg/kg p.o.) dose-dependently reduced the necrotic changes in rat liver and inhibited the increase of serum ALT and AST activities. The results of the present study indicated that the hepatoprotective effect of Orthosiphon stamineus might be ascribable to its antioxidant and free radical scavenging property.

Liver disease is a dysfunction that affects all or part of the liver and can lead to death. While the use of medicinal and aromatic plants has been a source of bioactive substances with hepatoprotective properties. This study aims to evaluate the hepatoprotective effect of the methanolic extract of Corrigiola telephiifolia roots on hepatic damage induced by carbon tetrachloride (CCl4) in mice. Animals were treated daily with C. telephiifolia methanolic extract (CTME) at doses of 5 and 10 mg/kg b.w for 60 days. In addition, CCl4 was injected (1 mL/kg, i.p.) for its hepatotoxic effects. At the end of the experiment, the blood of all animals was collected to evaluate biochemical parameters and the liver for histopathological analysis. The administration of CTME showed significant hepatoprotective activity by improving the biochemical parameters and the histological appearance of hepatic cells induced by CCl4. Consequently, C. telephiifolia could be used in the prevention and/or treatment of liver intoxication.

Liver plays an important role in maintaining the biological equilibrium of vertebrates. Liver diseases are a major worldwide health problem with high endemicity in developing countries. They are mainly caused by chemicals and some drugs when taken in very high doses. Despite advances in modern medicine, there is no effective drug available that stimulates liver function, offer protection to the liver from damage or help to regenerate hepatic cells. There is urgent need, therefore, for effective drugs to replace/supplement those in current use. The plant kingdom is undoubtedly valuable as a source of new medicinal agents. The main aim of any medication in the treatment of liver disorders is to prevent degeneration of hepatocytes and associated metabolic abnormalities and promote regeneration of hepatic cells. In present study the hepatoprotective activity of Cynodon dactylon extracts was evaluated in rifampicin induced liver toxicity by biochemical parameters like SGPT, SGOT, ALP, BIT and by histopathological study. Acute administration of rifampicin produced marked elevation of the serum levels of the above parameters compared to that of the control group. Treatment with ethanolic and aqueous extracts of Cynodon dactylon leaves at doses of 200 and 400 mg/kg produces significant prevention in rifampicin induced rise of the above parameters. Silymarin at 100 mg/kg body weight significantly prevented such rise in study. The effect of Cynodon dactylon leaves extracts was found possess promising hepatoprotective activity. Further studies in other species and on other parameter would throw more light on this plant.

Synthetic amorphous silica (SAS) nanomaterial – consisting of aggregates and agglomerates of primary silicon dioxide (SiO2) particles in the nanorange (<100 nm) – is commonly used as excipient in pharmaceuticals, in cosmetics and as food additive (E551). The available data suggest that SAS nanoparticles (NP) after intravenous (IV) exposure persist in liver and spleen; however, insufficient data exist to verify whether SAS may also induce adverse effects. The aim of the present study was to verify the potential long-term effects of SAS NP (NM-203) on spleen and liver as target organs following short-term exposure. Adult male and female Sprague-Dawley rats were treated by IV injection in the tail vein with a single (1-day) dose (SD) and repeated (5-day) doses (RD) of 20 mg/kg bw per day of SAS dispersed in sterile saline solution as vehicle. Histopathological examinations of target organs were performed after 90 days. Tissue biodistribution and full characterization of NM-203, primary particle size 13–45 nm, was performed within the framework of the Nanogenotox project. No mortality or general toxicity occurred; histopathological analysis showed splenomegaly in the RD group accompanied by inflammatory granulomas in both sexes. Granulomas were also present in liver parenchyma in the RD (both sexes) and SD groups (male only). The histopathological results indicated that SAS NP have the potential to persist and induce sex-specific chronic inflammatory lesions in spleen and liver upon short-term treatment. Overall, the data showed that the widespread use of silica in drugs might elicit chronic reactions in spleen and liver prompting to the need of further investigations on the safety of SAS NP.

The acetone (AEAC) and aqueous extracts (AQEAC) of Adina cordifolia, belonging to the family Rubiaceae, were studied for hepatoprotective activity against Wister rats with liver damage induced by ethanol. It was found that AEAC and AQEAC, at a dose of 500 mg/kg body weight exhibited hepatoprotective effect by lowering the Serum Glutamate Pyruvate Transaminase (SGPT), Serum Glutamate Oxaloacetate Transaminase (SGOT), alkaline phosphate and total bilirubin to a significant extent and also significantly increased the levels of total protein. The hepatoprotective activity was also supported by histopathological studies of liver tissue. Since results of biochemical studies of blood samples of ethanol treated rats showed significant increase in the levels of serum enzyme activities, reflecting the liver injury caused by ethanol and blood samples from the animals treated with AEAC and AQEAC showed significant decrease in the levels of serum markers, indicating the protection of hepatic cells against ethanol induced hepatocellular injury. The effects of AEAC and AQEAC were comparable with standard drug silymarin.DOI: http://dx.doi.org/10.3329/icpj.v1i9.11619 International Current Pharmaceutical Journal 2012, 1(9): 279-284

ABSTRACT: The study is designed for the evaluation of in-vivo Hepato protective and in-vitro Anti oxidant activity of ethanol extracts from the bark of Shorea robusta (Dipterocarpaceae) by CCl4 induced hepatotoxicity in rats. Ethanol extracts from the bark Shorea robusta (EESR) was evaluated for hepatoprotective activity in rats by inducing liver damage by CCl4. The anti oxidant activity of EESR was assayed by various in-vitro antioxidant methods and activities were compared to standard ascorbic acid. Ethanol extracts at an oral dose 200mg/kg and 400mg/kg exhibited a significant (*p<0.005) protective effects by lowering the level of SGOT, SGPT, ALP, Serum bilirubin, total cholesterol and increasing the level of total proteins as compared to Silymarin (50mg/kg) used as positive control. The extracts exhibit significant anti oxidant activity in various in vitro anti oxidant models.  From these studies we are concluding that, the ethanolic extracts of S.robusta have potent hepatoprotective effects and have anti oxidant properties, hence can be used as a natural product against liver damage.KEY WORDS: Anti oxidant, Carbon tetra chloride,  Hepatoprotective,  Shorea robusta

The objective of the current investigation was performed to assess the hepatoprotective potentials and in vivo antioxidant properties of methanol extract of Tephrosia pumila against thioacetamide induced liver damage in rats. The acute oral toxicity study of methanol extract was determined as per OECD guidelines and the extract was proved to be safe up to the dose of 2000mg/kg. The total duration of the study was 21 days and animals were divided into six groups. Hepatotoxicity was induced in the animals of all groups except normal control by single dose administration of Thioacetamide(100mg/kg) at first day of the study followed by animals were treated daily with standard drug sylimarin and methanol extract of Tephrosia pumila (100mg/kg, 200mg/kg and 400mg/kg) to respective groups for 21 days. Variations in biochemical parameters like alanine transferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), total bilirubin, direct bilirubin, albumin, total protein, ions and others parameters like clotting time and weight of the liver were considered to determine beneficial effect of the extract. At the end of the study liver samples were collected and subjected to histopathological evaluation. There were significant variations in the above mentioned biochemical parameters in toxic control animals treated with Thioacetamide alone while in the animals treated with methanol extract and standard drug silymarin, all the parameters were normal possibly due to their beneficial property in protecting the liver against thioacetamide induced hepatotoxicity. The results obtained in the above study suggesting that, the methanol extract of Tephrosia pumila possess significant hepatoprotective activity.

Clinacanthus Nutans

The present study aims for the first time to provide the in vivo acute toxicological profile of the highest dose of Clinacanthus nutans (Burm. f.) Lindau water leaf extract according to the Organization for economic co-operation and development (OECD) 423 guidelines through conventional toxicity and advanced proton nuclear magnetic resonance (1H-NMR) serum and urinary metabolomics evaluation methods. A single dose of 5000 mg/kg bw of C. nutans water extract was administered to Sprague Dawley rats, and they were observed for 14 days. Conventional toxicity evaluation methods (physical observation, body and organ weight, food and water consumption, hematology, biochemical testing and histopathological analysis) suggested no abnormal toxicity signs. Serum 1H-NMR metabolome revealed no significant metabolic difference between untreated and treated groups. Urinary 1H-NMR analysis, on the other hand, revealed alteration in carbohydrate metabolism, energy metabolism and amino acid metabolism in extract-treated rats after 2 h of extract administration, but the metabolic expression collected after 24 h and at Day 5, Day 10 and Day 15 indicated that the extract-treated rats did not accumulate any toxicity biomarkers. Importantly, the outcomes further suggest that single oral administration of up to 5000 mg/kg bw of C. nutans water leaf extract is safe for consumption.
