The current study aims to explore the hepatoprotective mechanisms of garlic extract through in vivo and in vitro assays. The in vitro investigation of antioxidant and anti-inflammatory potential showed maximum 67.5% of free radical scavenging and 71.36% albumin denaturation inhibition by 600 μg/mL garlic extract. To explore the hepatoprotective activity by in vivo experiments, the animals were orally intoxicated with 150 μL of CCl4 (1:1 v/v in olive oil) and treated with garlic extract (75 mg/kg b.w.) 3 times/week, for eight successive weeks. The administration of garlic extract significantly ameliorated CCl4 induced increment in amounts of serum Alanine aminotransferase (ALT), Alkaline phosphatase (ALP) and Aspartate transaminaseas (106.7, 116.3, 136.4 U/L) as compared to disease control which showed increased level (140.5, 156.2, 187.6 U/L). Besides, significant reduction of Superoxide dismutase (SOD), Glutathione peroxidases (GPx), and Glutathione (GSH) (29.3, 48.4, and 25.9 U/mg protein) was noticed in CCl4 induced animals, respectively. Likewise, garlic extract treatment facilitated a significant increment in all tested antioxidant enzymes levels (41.6, 63.3, and 32.5 U/mg protein), respectively. Additionally, Tumor necrosis factor⍺ (TNF-⍺), C-reactive protein (CRP), Interleukin-1β (IL-1β), Interleukin 6 (IL-6) and ICAM-1 (Intercellular Adhesion Molecule 1) level (63.79, 580.2, 18.3, 63.74 and 148.4 pg/mL) were increased significantly in CCl4-induced group, while garlic extract treatment decreased these pro inflammatory marker levels (40.24, 460.4, 15.4, 45.14, and 125.3 pg/mL). The animals exposed to CCl4 showed various types of alterations like lymphocytes infiltration, edema and congestion, while the animals treated with garlic extract plus CCl4 showed amelioration of the hepatocytes architectures. Thus, our finding advocates that the consumption of garlic can be a potential therapeutic remedy in the inhibition of liver ailments. |
