The parenchymal cells of the liver comprises of 70–80% and cover the entire liver. The oxidative stress can impart damage to the both parenchymal and non-parenchymal cells but exhibit different responses to the oxidative stress. The oxidative stress is associated with the necrosis and inflammation of the hepatic tissue. The oxidative stress mediated liver damage results in clinical hepatitis, fibrosis of the liver, cirrhosis and eventually hepatocellular carcinoma. These free radicals leads to the oxidation of the macromolecules such as cell membrane, lipids, proteins and DNA. The most commonly implicated oxidative free radicals includes superoxides and peroxides, which are released by various endogenous and exogenous substances. However, when the oxidative stress is increased beyond the neutralizing capacity, the liver is the most vulnerable site for the free radicals related tissue damage. These antioxidants system are induced by the hepatocytes to counter the offending oxidative stress. The liver is armed with the endogenous system of antioxidants enzymes such as glutathione-s-transferase (GST), GSH, Catalase and sulphuroxide dismutase (SOD). The liver tends to counter the oxidative stress by inducing the antioxidants mechanism, which neutralizes the reactive oxygen and nitrogen free (RONS) radicals. Liver is considered as vital organ of the body, which critically regulates several important functions of the body including biotransformation and detoxification of the endogenous and exogenous substances. Additionally, the poncirin treatment also markedly improved the antioxidant enzymes, attenuated the oxidative stress markers and inflammatory cytokines. The poncirin treatment showed marked improvement in behavioral, biochemical and histological parameters following CCL4-induced liver injury. Furthermore, the poncirin treatment also evidently decreased the inflammatory mediators. The H and E staining showed that poncirin treatment significantly improved the histology of liver compared to the CCL4 treated group. The anti-oxidants were induced, while oxidative stress markers were reduced promisingly. The hematological and biochemical parameters were significantly improved compared to the CCL4 treated groups. The liver weight variation was attenuated and total body was improved markedly. The poncirin treatment markedly improved the behavioral parameters such as food and water intake. The Swiss Target prediction software was used to investigate interaction of the poncirin on the various hepatic enzymes. The poncirin treatment was also evaluated against the pro-inflammatory cytokines such as interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) using enzyme link immunosorbant assay (ELISA). Furthermore, various hematological, biochemical parameters and histological studies such as hemotoxylin and eosin (H and E) staining were performed. Following the induction of the liver injury various parameters such as food and water intake, body weight and weight to dry ratio changes were assessed. The CCL4-induced acute and chronic liver injury model (albino BALB/c mice) was used. Based on the previous studies it was anticipated that the poncirin will ameliorate CCL4-induced liver injury. The poncirin have been reported for various anti-inflammatory, analgesic activity etc. The cytosol also contains large amounts of macromolecules that can alter how molecules behave, through macromolecular crowding.In the present study, the poncirin which is flavonoid-7-o-glycosides (isolated from the Poncirus trifoliata) in nature was evaluated against the Carbon tetra chloride (CCL4)-induced liver injury. The concentrations of ions, such as sodium and potassium, are generally lower in the cytosol compared to the extracellular fluid these differences in ion levels are important in processes such as osmoregulation and signal transduction. Although water forms the large majority of the cytosol, it mainly functions as a fluid medium for intracellular signaling (signal transduction ) within the cell, and plays a role in determining cell size and shape. The cytosol is a complex mixture of substances dissolved in water. The cytosol includes dissolved molecules and water. The cytosol: The cytosol (11) is the fluid within the plasma membrane of a cell and contains the organelles. The contents of a eukaryotic cell within the cell membrane, excluding the cell nucleus and other membrane-bound organelles (e.g., mitochondria, plastides, lumen of endoplasmic reticulum, etc.), is referred to as the cytoplasm. For example, the mitochondrial matrix separates the mitochondrion into compartments. It is separated into compartments by membranes that encircle the various organelles of the cell. The intracellular fluid of the cytosol or intracellular fluid (or cytoplasm ) is the fluid found inside cells.
