Evaluation of Hepatoprotective Activity of Caralluma europaea Stem Extract against CCl₄-Induced Hepatic Damage in Wistar Rats.

ABSTRACT: The present study aims to evaluate the hepatoprotective activity of stem aqueous extract of Caralluma europaea (AECe) on carbon tetrachloride- (CCl₄-) induced hepatic damage in Wistar rats. The animals were daily treated with the aqueous extract of C. europaea at a dose of 250?mg/kg body weight for 14 days. CCl₄ was injected (1?ml/kg, i.p.) two times, on the 7^th and 14^th days. At the end of the experimental period, all rats were anesthetized to collect blood for the assessment of biochemical parameters and then sacrificed to collect the liver for weighing. Hepatotoxicity was evaluated by measuring the serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin (total and direct), malondialdehyde (MDA), total protein (TP), triglycerides (TG), total cholesterol, very low-density lipoprotein (VLDL-c ), low-density lipoprotein (LDL-c), high-density lipoprotein (HDL-c), urea, creatinine, and uric acid. Based on the results obtained in this study, the administration of C. europaea before exposure to the administration of CCl₄ conferred favorable hepatoprotective effect in rats. The treatment with AECe (250?mg/kg) exhibits a significant hepatoprotective effect by ameliorating CCl₄-induced alterations of these biochemical parameters. Hence, C. europaea could be a potential medicinal herb that can be used in the future to prevent liver intoxication.

Project description:BackgroundThe increase in demand and consumption of single clove garlic or 'Solo garlic' (Allium sativum) has resulted in an increase in research on its therapeutic properties. The present study aims to evaluate the antioxidant activities, oxidant-scavenging efficiency and preventive effects of SCG (single clove garlic) and MCG (multi clove garlic) on CCl4-induced acute hepatotoxicity in male rabbits.MethodsFor this purpose, rabbits were orally administered with 3 ml of CCl4 /kg of body weight, followed by 0.8 g of MCG or SCG/kg twice a week for three successive weeks. Oxidative hepatotoxicity was then assessed.ResultsSCG extracts exhibited higher antioxidant capacity than the MCG extract. Scavenging ability of SCG showed significant (p < 0.05) elevation against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide radicals in comparison to MCG. In addition, total phenolic content of SCG was significantly elevated (p < 0.001), thereby suggesting that the composition of garlic storage constituents varies with the number of cloves present. CCl4-induced hepatotoxicity demonstrated histological changes including severe damage in the structure of liver tissues which correlated well to oxidative stress levels. Simultaneously, administration of SCG resulted in a significant reduction of serum alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin (TB) levels in addition to improvement in some histological parameters. Low levels of lipid peroxidation (malondialdehyde, MDA) (p < 0.001), along with a huge reduction in peroxidase (POx) (p < 0.001) revealed protection against oxidative toxicity in the liver homogenate. Higher levels of catalase (CAT) (p < 0.001) and superoxide dismutase (SOD) (p < 0.05) when compared to the MCG test (TM) group indicates that removal of H2O2 is based on CAT activity in SCG test (TS) group rather than the POx activity demonstrated in the former group.ConclusionThe present study indicates that SCG possesses more protective ability than MCG against CCl4-induced liver injury and might be an effective alternative medicine against acute oxidative liver toxicity.

Project description:BackgroundDegenerative kidney diseases are mostly associated with oxidative stress. Natural products are considered as the antioxidants enrich food that can restrict the progress of oxidative stress induced disorders. Therefore, the present study was aimed to evaluate the renal protective effect of Ajuga parviflora leaf extract in carbon tetrachloride intoxicated rats.MethodsThe hydromethanolic extract of A. parviflora leaves was obtained by extracting twice in 60% methanol. The principal bioactive constituents were detected by LC/MS analysis. Toxicity of plant extract was assessed using brine shrimp lethal toxicity test and acute toxicity model on healthy Sprague-Dawley male rats. Nephroprotective effects of plant extract were also evaluated on rats by inducing CCl4 renal toxicity in comparison with positive control and naïve groups. The dose of A. parviflora administered to animal was 100, 200 and 300 mg/kg. All administrations were given orally on an alternate day basis for 30 days. Urine and serum biomarkers were analyzed, along with antioxidant enzymes. Finally, the DNA damages, lipid peroxides, hydrogen peroxides and nitrites were assessed in rat's renal tissue. The histopathology alterations in renal tissues were further studied for kidney damages.ResultsThe LC/MS analysis confirmed the presence of different important pharmacological compounds in A. parviflora methanolic leaf extract. The key bioactive compounds include pyocyanin, zonisamide, D Saccharic acid, altretamine, carbocyclic thromboxane A2, Sinapyl alcohol, and vitamin C. The important polypeptides identified include Lys-Tyr-Lys, His-His-Lys, Met-Asp-Arg, Phe-Val-Arg, and PyroGlu-Val-Arg. The LD50 of A. parviflora was found to be > 1000 μg/mL. A. parviflora administration significantly subsides CCl4 toxicity in rats, reduced the elevated level of RBCs, pus and epithelial cells. The abnormal elevated level of specific gravity, creatinine, urobilinogen, urea and albumin were also reduced to normal physiological level. The reduced urinary protein and pH were also normalized. The serum urobilinogen, urea and total bilirubin levels were also reversed to normal levels while the diminished albumin and total protein levels also came to normal. The important phase I and II enzyme levels were also reversed in A. parviflora administered rats. The H2O2, thiobarbituric acid reactive substance (TBARS) and nitrite levels were significantly decreased. Furthermore, the damaged DNA and histopathological changes in CCl4 exposed rats were also highly significantly reversed after the administration of A. parviflora. All effects were significant (P < 0.05) and highly significant (P < 0.005) at 100 and 300 mg/kg respectively.ConclusionThe restored urine and serum profile of various parameters to normal physiological levels suggests that the A. parviflora has potential antioxidant and repairing potential in renal disorders.
