EVALUATION OF HEPATOPROTECTIVE EFFECT OF ETHANOLIC EXTRACT OF ROOT OF PUNICA GRANATUM IN RATS

Objective: To evaluate the hepatoprotective effect of ethanolic extract of the root (REE) of Punica granatum.Methods: This study was conducted on adult albino Wistar rats of either sex weighing 150-200 g. Animals were divided into five groups (n=5). Liver injury was produced by carbon tetrachloride (CCl4) 1 ml/kg dissolved in olive oil (1:1) given intraperitoneally on day 1 and day 4 of the study duration of 14 days. Silymarin (50 mg/kg/d) orally was used as standard drug. Test groups received an REE of P. granatum (REE) at doses of 200 and 400 mg/kg/day orally along with CCl4. On the 15th day, all animals were sacrificed, and blood was collected. Liver was sent for histopathological examination. The hepatoprotective effect of REE was evaluated by assessment of physical parameters, histopathological examination and biochemical parameters such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total serum bilirubin.Results: The administration of REE of P. granatum at doses of 200 and 400 mg/kg/day orally, exhibited a highly significant decrease in the rise of mean serum AST, ALT, ALP, and total bilirubin as compared to CCl4 treated group (p<0.001). Histopathological examination of the liver also suggested hepatoprotective effect of REE of P. granatum by restoration of hepatic architecture toward normal. Decrease in the extent of centrilobular necrosis was observed in REE (200 and 400 mg/kg/day) treated rats when compared to CCl4 treated group.Conclusion: This study demonstrated hepatoprotective activity of REE of P. granatum against CCl4 induced liver injury in rats.

Helicteres Isora

Helicteres isora L. is a medicinal plant which is used in several diseases, such as snake-bite, dog-bite, diarrhoea and constipation in a new born baby, gastrointestinal disorders, diabetes, cancer, and infections. This plant has also been used in the management of liver damage through traditional medicine. However, the hepatoprotective activity of H. isora L. ethanolic extract has not been reported so much. The present work was carried to investigate the hepatoprotective effect of H. isora L. against paracetamol-induced liver injury in Swiss mice. Paracetamol (PCM) is widely used as an analgesic and antipyretic drug which at high dose can lead to undesirable side effects, such as hepatotoxicity. Paracetamol induce hepatotoxicity was evaluated by an increase (P<0.05) in AST and ALT serum activity. Paracetamol hepatotoxicity was also manifested by an increase in (P<0.05) lipid peroxidation and depletion of reduced glutathione (GSH) in liver tissue. Ethanol extract of H. isora L. (250, 500 and 1000 mg/kg bw/day) significantly restored the PCM-induced alterations in the biochemical activities of blood and liver tissues. The hepatoprotective effect of H. isora L. was also confirmed by the histopathological examination of liver tissue. Histopathological examination of liver sections in mice administered with 1000 mg/kg bw/day doses of the extract were perfectly protected almost similar to those of untreated mice. The results indicated the hepatoprotective nature of studied plants extract against paracetamol induced toxicity. Our study scientifically validates the folkloric claim as well as traditional uses of H. isora L. as hepatoactive medicine. The results of this study suggests a new direction in the treatment of liver disease in future.

The objective of present work is Development of Hepatotoxicity model in rats and to evaluate hepatoprotective activity of cell wall contents of probiotics. Animals were divided in four groups. The groups were normal saline group, diseased control group, standard drug treated group and 4th group was CCl4 +Cell wall contents of probiotics. In diseased control group chronic liver injury was induced by administration of Carbontetrachloride (CCl4) via intraperitoneal route (1 ml/kg) for seventy days. For standard drug treated group 1 ml Silymarin suspension (Orally) and CCl4 was given for seventy days. In fourth group cell wall contents (1 x 10 12 CFU/ml/animal) and CCl4 was given for seventy days. During disease induction and treatment period blood samples were collected and serum was separated which was used to analyse various parameters like Alanine aminotransferase (ALT), Aspartate aminotransferase, (AST), Alkaline phosphate (ALP), direct bilirubin, total protein and albumin levels to asses liver function. Along with these cholesterol, Glucose and Malondialdehyde were also measured. Liver fibrosis and cirrhosis was quantified by histopathological studies of small portion of the excised liver. Serum AST, ALT, ALP, and direct bilirubin were found to be significantly higher in CCl4 intoxicated rats. Total protein and albumin was decreased. Manondialdehyde was found to be significantly higher in CCl4 intoxicated rats which was main end product of Lipid Peroxidation. Whereas in cell wall contents probiotics and silymarin treated group improve the liver functions in CCl4 toxicated rats. We conclude that protein oxidation may play a role in the pathogenesis of CCl4 induced liver injury and that the accumulation of oxidised proteins may be an early indication of CCl4 induced liver damage. Silymarin and cell wall contents of probiotics were effective in liver injury by inhibiting protein oxidation.

The present study was designed to assess the possible hepatoprotective activity of the leaf ethanolic extract of coded plant (Code No. 222**) against carbon tetrachloride (CCl4)-induced hepatic injury in Wistar albino rats. The animals were divided into different groups and treated with 222 leaf ethanolic extract at different concentrations for five days. Silymarin, the known hepatoprotective standard compound (100 mg/kg) was administered for five days. Hepatotoxicity was induced by the subcutaneous administration of a single dose of CCl4: Olive oil (2 mL/kg) on days 2 and 3. The administration of CCl4 resulted in marked increase in serum hepatic enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST) and serum bilirubin levels. CCl4 intoxication also resulted in a significant (P=0.05) increase in malondialdehyde (MDA), which is a common marker of lipid peroxidation. The other biochemical parameters such as cholesterol, triglycerides, creatinine, urea and uric acid levels were also increased significantly (P=0.05) compared to normal control group. Changes in serum hepatic enzymes, biochemical parameters and MDA levels induced by CCl4 were reversed by the leaf ethanolic extract of 222 (125 mg/kg) dose. The standard drug silymarin treated group also reversed CCl4-induced changes in biomarkers of liver function and MDA levels. Histopathological studies of the liver samples confirmed the hepatoprotective property of the coded drug 222. It was seen that histopathological damage induced by CCl4 were improved in rat liver, treated with 222 extract. The results of the present study suggested that coded plant (222) leaf ethanolic extract may be used as a hepatoprotective agent against toxic effects caused carbon tetrachloride in the liver.

This study investigates the hepatoprotective activity of ethanol extract from Shidagonglao roots (SDGLEtOH). The hepatoprotective effect of SDGLEtOH(20, 100 and 500 mg/kg) was analyzed on carbon tetrachloride ( CCl4)-induced acute liver injury. Rats pretreated orally with SDGLEtOH(100 and 500 mg/kg) and silymarin (200 mg/kg) for 3 consecutive days prior to the administration of a single dose of 50% CCl4(0.10 ml/100 g of bw, ip) significantly prevented the increases in the activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in CCl4-treated rats. Histological analysis also showed that SDGLEtOH(100 and 500 mg/kg) and silymarin reduced the incidence of liver lesions including vacuole formation, neutrophil infiltration and necrosis of hepatocytes induced by CCl4in rats. Moreover, the SDGLEtOH(100 and 500 mg/kg) increased the activities of anti-oxidative enzymes, superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GRd) and decreased malondialdehyde (MDA) level in liver, as compared to those in the CCl4-treated group. Furthermore, SDGLEtOH(100 and 500 mg/kg) and silymarin attenuated the increased levels of tumor necrosis factor-α (TNF-α) in serum and nitric oxide ( NO ) in liver as compared to the CCl4-treated group. The hepatoprotective mechanisms of SDGLEtOHare likely related to inhibition of TNF-α, MDA and NO productions via increasing the activities of antioxidant enzymes (SOD, GPx and GRd). These experimental results suggest that SDGLEtOHcan attenuate CCl4-induced acute liver injury in rats.

Tuberculosis (TB) is one of the leading causes of death in developing countries. One of the problems in controlling TB disease is that most anti-tuberculosis drugs are hepatotoxic. Citrus sinensis peel extract is the rich source of secondary metabolites with high potential effectiveness as an antioxidant. In the present study, we evaluate the hepatoprotective effect of Citrus sinensis peel ethanolic extract (CSPEE) on isoniazid and rifampicin-induced liver injury in Wistar rats. Twenty five adult male Wistar rats were divided into 5 groups of 5 each : control, (INH+RIF) (50 mg/kg bw once a day for 14 days), (INH+RIF) + various dose of CSPEE (300, 450, 600 mg/kg bw). CSPEE was given orally once a day for 14 days followed by administration of INH + RIF suspension. The measurement of serum ALT and AST were carried out on the 15th day. Histopathologic examination of the liver was also performed. The Serum ALT and AST of the rats that induced with INH + RIF were increased significantly (P<0.001) compare to those of control groups, and the histopathologic slides showed steatosis, vacuolation and necrosis of hepatic cells. The serum ALT and AST in groups treated with CSPEE were not significantly different (p>0.05) with those of control groups. The serum ALT and AST and histopathological examination of the liver of the group that administered 600 mg/kg CSPEE were closest to normal rats. Citrus sinensis peel extract exhibits hepatoprotective effect on liver injury induced with INH + RIF in Wistar rats.

The hepatoprotective activity of ethanolic extract from the leaves ofVitex negundo(VN) was conducted against thioacetamide- (TAA-) induced hepatic injury inSprague Dawleyrats. The therapeutic effect of the extract was investigated on adult male rats. Rats were divided into seven groups: control, TAA, Silymarin (SY), and VN high dose and low dose groups. Rats were administered with VN extract at two different doses, 100 mg/kg and 300 mg/kg body weight. After 12 weeks, the rats administered with VN showed a significantly lower liver to body weight ratio. Their abnormal levels of biochemical parameters and liver malondialdehyde were restored closer to the normal levels and were comparable to the levels in animals treated with the standard drug, SY. Gross necropsy and histopathological examination further confirmed the results. Progression of liver fibrosis induced by TAA in rats was intervened by VN extract administration, and these effects were similar to those administered with SY. This is the first report on hepatoprotective effect of VN against TAA-induced liver fibrosis.
