Purpose Our research aims to address and determine the effect of Camellia sinensis extract in the management of nonalcoholic steatohepatitis (NASH) in rats. Methods Forty adult female albino rats were divided into four groups. Group 1 (G1) served as the control group, while the other three groups received high-fat diet for 32 weeks to induce NASH and then were later assigned to the following groups: (G2) NASH-afflicted group which was left untreated, (G3) NASH-afflicted group treated with Camellia sinensis extract in a dose of 400 mg/kg, and (G4) NASH-afflicted group treated with Camellia sinensis extract in a dose of 200 mg/kg. Results Significant elevation in serum alanine aminotransferase, albumin, bilirubin (total and direct), cholesterol, low density lipoprotein, triglycerides, leptin, Cox-2, and CD40 values was recorded. Moreover, overexpression of hepatic tumor necrosis factor alpha and hepatocyte growth factor genes were recorded, whereas blood platelet count and serum high density lipoprotein concentration revealed significant depletion, which was paralleled by significant downregulation of hepatic adiponectin gene expression level in NASH group versus the control group. On the opposite side, treatment of NASH groups with two different doses of Camellia sinensis extract reversed the values of the measured biochemical parameters and the targeted gene expression levels when compared with the NASH group. Optical micrograph of liver tissue sections of rats treated with Camellia sinensis extract showed the observed improvement in the studied biochemical and genetic markers. Conclusion This study provides a clear evidence for the promising therapeutic potential of Camellia sinensis extract against NASH. This could be ascribed to its hepatoprotective activity, hypolipidemic effect, and anti-inflammatory potency.

From the phenolic profile of Acacia pennata L. leaves hydromethanolic extract, nine flavonoids were tentatively character- ized (liquid chromatography-electrospray ionization mass spectrometry), of which Kaempferol 3,7-di-O-hexoside, Apigenin 6,8-di-C-hexoside, Luteolin-6-C-pentoside-8-C-hexoside, Apigenin-6-C-hexoside-8-C-pentoside and Apigenin-6-C-pento- side-8-C-hexoside were detected for the first time from the plant. Three doses of the plant extract (12.5, 25 and 50 mg/kg bw/d, four weeks treatment) were used to assess its protective effect against acetominophen induced genotoxicity in hepatic cells of male rats (2 g/kg bw twice per week). A. pennata extract and Acetominophen treated animal groups attenuated DNA damage rates (Comet assay) by 5.6, 6.2 and 6.4% for the three doses, respectively, compared with the acetaminophen treated and untreated groups by 21.2% and 5.8%, respectively. It also decreased DNA fragmentation, significantly down-regulate the expression of p53 tumour suppressor gene and mdr1b multidrug resistance gene [real-time PCR (qPCR)] and ROS genera- tion rates induced by Acetaminophen by 715.4, 453.8 and 376.9% in rats in a dose dependant effect. The results highlighted the DNA protection potential of A. pennata phytoconstituents from drug abuse harmful effects.
