Hepatoprotective Activity of Flavonoids Purified and Ethanolic Extract from Iraqi Propolis Against Carbon tetrachloride-Induced Liver Damage In Male Mice

In this study we investigated the in vivo Hepatoprotective activity of ethanolic extract of Garuga pinnata (EEGP) leaves in Carbon tetrachloride (CCl4) induced hepatotoxicity using wistar rats of either sex as model. Hepatotoxicity was induced by the administration of CCl4 intraperitoneally (0.125ml CCl4 in liquid paraffin (1:1) per 100g body weight). Garuga pinnata leaves extract at different dose levels (200 and 400mg/kg, p.o.) showed the dose dependant hepatoprotective effect and was compared with well known standard hepatoprotective Silymarain (100mg/kg). When groups were treated with CCl4, significant increase in serum biochemical parameters such as Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transaminase (SGPT), Alkaline phosphate (ALP), Acid Phosphate (ACP), Creatinine and alteration of tissue biochemical parameters such as reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), lipid peroxidation (LPO), and the total proteins were observed. The histopathological examination of the CCl4 treated groups showed sinusoidal congestion, centrilobular necrosis, marked vacuolations and congestion. However, pretreatment with extract of leaves of Garuga pinnata significantly reduced the increased serum levels of biochemical parameters and restored antioxidant defense enzymes level to its normal. Moreover, histopathology of leaves extract treated groups showed normal architecture with minimal sinusoidal congestion. Taken together, our study concludes that EEGP to be a more potential agent for caring liver from CCl4 induced damage.

The protective activity of the total saponins fromActinidia valvataDunn root (TSAV) was studied against carbon-tetrachloride- (CCl4-) induced acute liver injury in mice. Mice were orally administered TSAV (50, 100, and 200 mg/kg) for five days and then given CCl4. TSAV pretreatment significantly prevented the CCl4-induced hepatic damage as indicated by the serum marker enzymes (AST, ALT, and ALP). Parallel to these changes, TSAV also prevented CCl4-induced oxidative stress by inhibiting lipid peroxidation (MDA) and restoring the levels of antioxidant enzymes (SOD, CAT, GR, and GPX), GSH and GSSG. In addition, TSAV attenuated the serum TNF-αand IL-6 levels and inhibited the serum iNOS and NO levels. Liver histopathology indicated that TSAV alleviated CCl4-induced inflammatory infiltration and focal necrosis. TSAV (200 mg/kg) also significantly decreased Bak, Bax mRNA and Fas, FasL, p53, and NF-κB p65 protein expressions and increased Bcl-2 mRNA and protein expressions. Meanwhile, TSAV significantly downregulated caspase-3 and caspase-8 activities and prevented CCl4-induced hepatic cell apoptosis. In addition, TSAV exhibited antioxidant activity through scavenging hydroxyl and DPPH free radicalsin vitro. These results indicated that TSAV could protect mice against CCl4-induced acute liver damage possibly through antioxidant, anti-inflammatory activities and regulating apoptotic-related genes.
