Inflammatory Effect

Dipterocarpus tuberculatus Roxb. has been used traditionally as a remedy for many diseases, especially inflammation. Therefore, we analyzed and explored the mechanism of the anti-inflammatory effect of a Dipterocarpus tuberculatus Roxb. ethanol extract (Dt-EE). Dt-EE clearly and dose-dependently inhibited the expression of pro-inflammatory cytokines such as IL-6, TNF-α, and IL-1β in lipopolysaccharide (LPS)-treated RAW264.7 cells. Also, Dt-EE suppressed the activation of the MyD88/TRIF-mediated AP-1 pathway and the AP-1 pathway related proteins JNK2, MKK4/7, and TAK1, which occurred as a result of inhibiting the kinase activity of IRAK1 and IRAK4, the most upstream factors of the AP-1 pathway. Finally, Dt-EE displayed hepatoprotective activity in a mouse model of hepatitis induced with LPS/D-galactosamine (D-GalN) through decreasing the serum levels of alanine aminotransferase and suppressing the activation of JNK and IRAK1. Therefore, our results strongly suggest that Dt-EE could be a candidate anti-inflammatory herbal medicine with IRAK1/AP-1 inhibitory and hepatoprotective properties.

Purpose: To determine the phenolic and flavonoid contents of R. sativus rhizome ethanol extract and the hepatoprotective effect of the extract in rats. Methods: Folin–Ciocalteau and aluminum chloride colorimetric tests were used to determine the contents of phenols and flavonoids in the R. sativus extract. Male Sprague-Dawley rats induced with CCl4 to develop hepatotoxicity were treated orally with R. sativus extract for 4 weeks. The  antioxidant and anti-inflammatory effects of the extract on the liver were determined by evaluating the concentration of oxidative analytes, serum liver enzymes and lipids, and hepatic histopathology and cytochrome P450 2E1 expression. Results: R. sativus extract significantly (p < 0.05) reduced the hepatotoxic effect of CCl4 via its antioxidant activities and protection of liver tissues from oxidative damage. Conclusion: The hepatoprotective effects of R. sativus rhizome ethanol extract are attributed to its highphenolic and flavonoid contents.

Abstract In the context of failure of treatment for non alcoholic fatty liver disease (NAFLD)-mediated systemic damages, recognition of novel and successful characteristic drug to combat these anomalous situations is earnestly required. The present study is aimed to evaluate protective value of ethanol extract of Coccinia grandis leaves (EECGL), naturally occurring medicinal plant, on NAFLD-mediated systemic damage induced by high lipid diet along with monosodium glutamate (HM)-fed rats. Our study uncovered that EECGL significantly ameliorates HM-induced hyperlipidemia, increased lipogenesis and metabolic disturbances (via up regulation of PPAR-α and PPAR-γ), oxidative stress (via reducing the generation of reactive oxygen species and regulating the redox-homeostasis) and inflammatory response (via regulating the pro-inflammatory and anti-inflammatory factors with concomitant down regulation of NF-kB, iNOS, TNF-α and up regulation of eNOS). Furthermore, EECGL significantly inhibited HM-induced increased population of cells in sub G0/G1 phase, decreased Bcl2 expression and thereby loss of mitochondrial membrane potential with over expression of Bax, p53, p21, activation of caspase 3 and 9 indicated the apoptosis and suppression of cell survival. It is perhaps the first comprehensive study with a mechanistic approach which provides a strong unique strategy for the management of HM-induced systemic damage with effective dose of EECGL.

Delonix elataL. (Ceasalpinaceae), is widely used by the traditional medical practitioners of Karnataka, India, to cure jaundice, and bronchial and rheumatic problems. The objective of this study was to screen thein vitroantioxidant and hepatoprotective activity of the stem bark extracts against CCl4-induced liver damage in rats. Among different stem bark extracts tested, the ethanol extract (DSE) has shown significantin vitroantioxidant property in radicals scavenging, metal chelating, and lipid peroxidation inhibition assays. HPLC analysis of the DSE revealed the presence of known antioxidant molecules, namely, gallic acid, ellagic acid, coumaric acid, quercetin, and rutin. Bioassay-guided fractionation of DSE has resulted in the isolation and characterization of quercetin. DSE and quercetin have shown significant prophylactic effects by restoring the liver function markers (AST, ALT, ALP, serum bilirubin, and total protein) and antioxidant enzymes (SOD, CAT, GPx, and GST). These results were proved to be hepatoprotective at par with silymarin and well supported by the histological observations of liver sections with distinct hepatic cells, and mild degree of fatty change and necrosis. The results indicated that the DSE and quercetin were significant for prophylactic activity against CCl4-induced liver damage in rats. This activity could be attributed to the antioxidant constituents in the DSE and hence justified the ethnomedicinal claims.

Introduction: Isoniazid (INH) and rifampin (RIF) are antituberculosis drugs that can induce injury in the liver. The purpose of this study was to investigate the antioxidant and hepatoprotective activities of the ethanol extract of Curcuma heyneana rhizome on liver injury in animal model induced by INH and RIF. Methods: Antioxidant activity was measured by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. All animals were divided into 7 groups. Liver injury was induced by using combination of INH at the dose of 50 mg/kg and RIF at the dose of 100 mg/kg. These drugs were administrated for 15 days along with extracts at doses of 5, 25, 125 or 625 mg/kg. Positive control group was given catechin. On the 16th day, the rats were sacrificed, blood and livers were collected for assessment of biochemical parameters like alanine transaminase (ALT) and aspartate transaminase (AST) and histological studies, respectively. Results: The ethanol extract strongly scavenged DPPH with inhibition concentration 50 (IC50) of 82.48 ppm. Administration of ethanol extract of C. heyneana rhizome at the dose of 25, 125 or 625 mg/kg significantly inhibited the elevation of AST and ALT (P<0.01). Moreover, the effects caused by administration of the extracts were similar to the effects caused by catechins. Various doses of the extract could effectively reduce tissue damage. Conclusion: This result suggests that ethanol extract of C. heyneana rhizome at the doses of 25, 125 and 625 mg/kg might be effective as hepatoprotective agent.

This study was carried out to investigate the protective effect of ethanol extract of Curcuma mangga rhizomes on paracetamol-induced hepatotoxicity. High dose of paracetamol (1.35g/kg bw) was used to induce hepatic necrosis of mice liver. The male mice  received ethanol extract of C. mangga rhizomes (100, 200 and 400 mg/kg BW) for 7 days. The hepatoprotective actvity of extract was compared to normal, positive (curcuma) and negative control. The liver function was evaluated by measuring the biochemistry parameters which include alanine aminotransferase (ALT) and aspartate aminotransferase (AST). In addition, histophatological study on hepatic tissue section was also carried out. The C. mangga extract displayed hepatoprotective effect except at dose of 100 mg/kg bw. The increasing of serum levels of AST and ALT were inhibited after treatment with ethanol extract at doses of 200 and 400 mg/kb bw which was comparable with normal and curcuma as postive control (p>0.05). In addition, histological assessment of hepatic tissue demonstrated no liver damage, specially at dose of 400 mg/kb BW. The result indicate that ethanol extract of C. mangga rhizomes has hepatoprotective effect, especially at doses of 200 and 400 mg/kg bw .   Keywords: C. mangga, rhizomes, biochemistry parameters, histopathology
