Aescin and diosmin each alone or in low dose- combination ameliorate liver damage induced by carbon tetrachloride in rats



This study evaluated hepatoprotective effect of aescin (AES) and diosmin (DIO), individually or in low-dose combination in chemically induced liver injury in rats. Rats were divided into 6 groups; Group 1, control, Group 2, injected with a single dose of a mixture of corn oil and carbon tetrachloride (CCl4) to induce hepatic toxicity. Before CCl4 injection, Groups 3–6 were treated daily for 14 days with silymarin (SIL) (200 mg/kg), aescin (AES; 3.6 & 1.75 mg/kg), Diosmin (DIO; 100 & 50 mg/kg). Serum samples were analyzed for different liver function, oxidative stress and antioxidant markers. Moreover, inflammation and tissue damage were confirmed by histological staining of liver tissue sections.


Results indicated that CCl4 elevated serum levels of all assessed liver function markers and decreased levels of key antioxidants. Administration of AES and/or DIO significantly reversed all those CCl4-induced effects. Histopathological study showed disruption of the hepatic architecture, necrosis and inflammatory cells and depositions of glycogen and protein in the tissues of CCl4-treated group. Pretreatment with DIO and/or AES significantly improved histopathological structure of liver tissue. In conclusion, low-dose combination of AES and DIO exhibited significant and preferential hepatoprotective activity compared to individual treatment with AES or DIO.


Liver damage is viewed as a worldwide medical and economic burden that is often inclined by viral infection, poisonous synthetic concoctions, and hepatotoxic drugs [1]. The liver assumes an irreplaceable job in the digestion of xenobiotics and therapeutic agents being detoxified and excreted [2]. Chemically‐induced hepatic damage is mainly evoked by the metabolic change of chemical into free radicals, which can truly influence cell macromolecules [2]. Carbon tetrachloride (CCl4)—induced liver damage has been for quite some time utilized as hepatic damage model to evaluate the therapeutic potential of drugs. This model has also been used in mechanical liver injuries that are comparable to human liver disease both in morphology and the biochemical characteristics of cellular lesions [2]. This hepatotoxic agent induces hepatic necrosis through the generation of trichloromethyl free radical under the effect of cytochrome p-450 2E1 [3].

Previous investigations have reported that a wide spectrum of natural products can prevent or even treat different types of liver diseases [4,5,6,7,8,9]. β-Aescin (AES) is a triterpene saponin derived from the horse chestnut tree Aesculus hippocastanum L. (Hippocastanaceae). Traditionally, leaves, bark and seeds were used to treat arthritis, brain trauma, stroke, venous congestion and thrombophlebitis [10]. There are different formulations of AES in clinical applications, including oral tablets, injections, and topical gel. AES is widely used in the clinical therapy because of its anti-apoptotic, anti-edematous, anti-inflammatory, and antioxidant effects [11,12,13]. Moreover, some studies reported anti-inflammatory, anti-oxidative stress and protective effects of AES against liver damage induced in animals by endotoxin [14], methyl parathion [15] and CCl4 [16].

Diosmin (DIO) (3′5,7-trihydroxy-4′-methoxyflavone 7-rutinoside) is an unsaturated flavonoid glycoside, present in citrus fruits [17]. DIO formulations are used to treat chronic venous insufficiency, hemorrhoids, venous ulcers (especially of the lower limbs) and to prevent postoperative thromboembolism [18]. Previous investigations reported anti-inflammatory, anti-oxidative stress and protective effects of DIO against liver damage induced in animals by ethanol [19], methotrexate [20], iron [21] and by aflatoxin [22]. Moreover, DIO successfully relieved mitochondrial oxidative stress effect against isopropanol-induced myocardial injury in rats [23]. In that context, AES and DIO have received considerable attention to their tremendous potential for management of various forms of hepatopathy [14, 15, 19,20,21,22]. Assessing AES/DIO and their combination against induced-liver damage is the objective of this study.

Results and discussion

AES, DIO and their combination attenuated liver lesions in CCl4-induced liver damage

Normal liver sections “control group” showed typical hepatic architecture with the central vein centrally located and normally thickened hepatic cords radiating with well-formed hepatocytes with centrally located nuclei and intact cell membrane (Fig. 1A). CCl4-induced group showed hepatocytes degenerative changes including pyknotic nuclei. In addition, central veins were massively enlarged and clogged with ductular cells hyperplasia, scattered inflammatory cells which were concentrated around hepatic vessels (Fig. 1B). Compared to the SIL + CCl4 group (Fig. 3C) and to the protected groups; treated with ASE (Fig. 3D), DIO (Fig. 1E), animals intoxicated with CCl4 and treated with both AES and DIO at low dose combination showed marked degree of improvement of hepatic tissue as the hepatic tissue restored its normal structure and architecture with centrally located central vein and intact hepatocytes (Fig. 1F). Currently, CCl4-induced liver injury is a model that is widely employed to screen for anti-hepatotoxic/hepatoprotective drugs. It is also a useful tool to study different liver illnesses, such as fatty liver, fibrosis, and cirrhosis [2, 28]. The magnitude of CCl4 hepatic impairment is evaluated by the enhanced serum level of cytoplasmic enzymes and by histopathologic changes in liver [29, 30].

Serum markers of liver damage ALT (G), AST (H) activities. Data are presented as mean ± SEM. (n = 6/group). a P < 0.05 vs. control group. b P < 0.05 vs. CCL4 group

Compared to control, CCl4-induced group had significantly higher levels of serum alanine aminotransferase (ALT) (130%), and aspartate aminotransferase (AST) (40%) (Fig. 1G, H). Levels of ALT and AST were significantly (P ≤ 0.05) improved upon treatment with SIL, AES and DIO. Pretreatment with SIL, AES, DIO and their combination reduced the elevated serum ALT by 28%, 34%, 31% and 21%, respectively, and AST levels by 31%, 33%, 29% and 32%, respectively, compared to animals in CCl4 group (Fig. 1G, H). Upregulation of ALT and AST have been ascribed to hepatotoxicity as they are released into blood serum upon hepatocyte degeneration [31]. The current study showed quite a restoration of almost normal levels especially when combined treatment was applied.

Glycogen and proteins distribution

Figure 2 shows the distribution of glycogen contents in normal liver tissue as reflected by PAS positivity area (Fig. 3A; 20.74 ± 1.65). CCl4 group showed severe depletion of glycogen 6.63 ± 1.6 with a reduction percent of 82.45% from the control group.

Data are presented as mean ± SEM (n = 6/group). a P < 0.05 vs. control group. b P < 0.05 vs. CCl4 group

Groups treated with DIO, AES and both showed varying improvements in the glycogen content as reflected by the PAS area  % of 15.84 ± 1.23, 16.54 ± 0.79 and 22.56 ± 1.36 respectively. Hepatotoxicity is always correlated with disruption in the synthesis and metabolism of glycogen and proteins. From the present findings, both protein and glycogen were reduced in CCl4 group. Poisonous effect on liver may mainly contribute to such reduction through the drug-induced necrosis of the plasma membrane, or via depleting energy sources needed for synthesizing protein and other metabolic events through obstructing the oxidative phosphorylation activity as documented elsewhere [32]. All tested preventive treatments successfully reversed such effect.

The control group showed the highest protein content (as reflected by Mercuric bromophenol blue positively stained area of the hepatocytes and its optical density of 26.75 ± 0.812 and 25.76 ± 1.66; Fig. 3). CCl4-intoxicated group showed the lowest comparable values of 2.29 ± 0.61 and 13.9 ± 0.98. Protected groups treated by AES and DIO showed varying degrees of protein content improvements; 16.037 ± 1.45 and 15.913 ± 1.7 and optical density of 17.88 ± 1.01 and 16.66 ± 0.08 respectively. The combined administration of AES and DIO at low dose, strengthened the stain reaction and showed marked improvement in the protein content of hepatocytes of 19.27 ± 0.8 and optical density of 20.59 ± 0.9. The present results of pre-administration of AES improved liver histology and function and significantly enhanced total hepatic glycogen and protein content. These results confirmed the hepatoprotective effect of AES as previously reported against liver damage induced by methyl parathion [15] and CCl4 [16, 22] in rats. Although treatment with DIO do positively contribute to liver histology and function, the protective effect of DIO was less evident than that of AES. These hepatoprotective effects of DIO coincide with those of [15, 19, 20]. Interestingly, livers of rats in CCl4 group treated with both AES and DIO showed minimal inflammation, eosinophilic staining and degenerations with significant enhancements in overall glycogen and protein contents in liver.

AES, DIO and their combination ameliorated oxidative stress and inflammation in CCl4-induced liver damage in rats

The administration of SIL, AES, DIO and AES/DIO combination significantly attenuated the increment in serum MDA and nitric oxide (NO) levels and partly attenuated the decrement in glutathione (GSH), Catalase and protein kinase C (PKC). Compared to SIL, AES, DIO and AES/DIO groups, the treatment with combined AES and DIO showed the best effects against all examined oxidative stress markers (Additional file 2). Abundant evidence suggests that reactive oxygen species (ROS) and other free radicals are induced following hepatic insults with drugs like CCl4. The enzymatic/non-enzymatic defense system is the natural protec-tor against free radicals accumulation [28, 30]. The accumulation of free radicals can cause decreased Catalase and GSH levels and a decline in capacity of scavenging free radicals. Consisting with previous report [30, 33], liver damage shown in CCl4-treated group was associated with enhanced MDA and NO as well as depletion of GSH and Catalase. Oxidative stress is known to cause activation of several stress kinases such as PKC and leads to exacerbation of cell toxicity [34]. The elevation of PKC in the present work was in line with the results of the previous studies which suggested that the hepatic oxidative stress and injury induced by bezafibrate [34] and acetaminophen [35] and CCl4 [36] was mediated by elevation of PKC. PKC induces upregulation of tumor necrosis factor- α (TNF-α), interleukin-6 (IL-6), and ROS, a major contributor to CCl4-induced liver injury [36]. Here, and in agreement with results of [16], AES ameliorated CCl4-induced hepatotoxicity by reducing MDA and NO and increasing GSH activity. Similarly, in this study, DIO mitigated CCl4-induced oxidative and nitrative stresses confirming previous studies that showed that DIO alleviates the oxidative stress caused by aflatoxin [22], methotrexate [20] by increasing GSH levels, lowering NO levels, and enhancing the activity of antioxidant enzymes. Most interestingly, much improvement in oxidative stress and antioxidants status was observed here when AES was combined with DIO.


This study was primarily focused on the assessment of tested extracts in induced liver fibrosis in animal model, more investigations are required for more understanding of the molecular mechanisms by which AES and DIO each alone or in low-dose combination might exert their beneficial hepatoprotective effect such as their effects on the inhibition of cytochrome CYP2E1 activity.
