Background and Aim: Propolis has a protective effect against cellular damage caused by toxic agents such as drugs, metals, xenobiotics, and chemicals. The aim of this study was to investigate the antioxidant activity and the effect of ethanolic extract of propolis on carbon tetrachloride (CCl4)-induced oxidative stress on kidney and liver injury in rat. Materials and Methods: The study quantified phenol, flavone, and flavonol in propolis and assessed antioxidant activity using 2, 2-diphenyl-1-picrylhydrazyl, ferric reducing antioxidant power, and molybdate. The investigators used four groups of rats to study the effect of propolis on CCl4-induced toxicity. Propolis extract was given orally (500 mg/kg) for 12 days, and CCl4 (1 mL/kg) was administered intraperitoneally on day 5 of the experiment. Blood and tissue samples of the liver and kidney were collected on day 13 to measure biochemical and oxidative parameters. The parameters included malondialdehyde (MDA), protein carbonyl formation (PCO), advanced oxidation protein products (AOPP), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH), and ascorbic acid (AA). Biochemical parameters included liver enzymes, blood urea (BU), creatinine, and uric acid (UA). Results: CCl4 decreased antioxidant agents, including CAT, GPx, GSH, and AA in the liver and kidney tissues. The oxidative agents' levels, including MDA, PCO, and AOPP, increased by CCl4 compared to the control group. CCl4 increased liver enzymes, UA, BU, and creatinine in the blood samples. Propolis significantly alleviated liver and kidney function, improved antioxidant parameters, and decreased levels of oxidative agents. Conclusion: The data showed for the 1st time that Moroccan propolis has a protective effect against CCl4-induced kidney and liver toxicity by maintaining the activity of the antioxidant defense system, which was most likely due to its antioxidant activity.

Propolis is a natural product produced by bees that was discovered through the study of traditional cures and knowledge of indigenous people throughout the world. It is rich in vitamins A, B, C, and E, and in amino acids, copper, iron, manganese, and zinc. The investigators studied the duration-dependent hepatoprotective effects of propolis extract (200 mg/kg, orally) against carbon tetrachloride (CCl 4 ; 1.5 mL/kg, intraperitoneally)-induced liver damage in rats. Administration of CCl 4 caused a sharp elevation in the activity of serum transaminases and serum alkaline phosphatase. A significant depletion in hepatically reduced glutathione was observed with significantly enhanced hepatic lipid peroxidation. After CCl 4 administration, glycogen contents and activities of alkaline phosphatase, adenosine triphosphatase, and succinic dehydrogenase were significantly decreased, whereas total protein contents and activity of acid phosphatase were increased in the liver and kidney. Propolis extract reversed alterations in all parameters when administered within 6, 12, and 24 h of toxicant exposure. Propolis therapy produced duration-dependent protection, with maximal protection achieved at 24 h after CCl 4 exposure. It is believed that propolis in its natural form has general pharmacologic value and marked hepatoprotective potential because of its composition of minerals, flavonoids, and phenolic compounds.
Prophylactic Effect Of Aqueous Propolis Extract Against Acute Experimental Hepatotoxicity In Vivo
Zeitschrift für Naturforschung C, 2002
Propolis has been extensively used in folk medicine for the management of a wide spectrum of disorders. In a previous study, we demonstrated the protective effect of the aqueous propolis extract (APE) against the injurious effects of carbon tetrachloride (CCl 4 ) on hepatocytes in vitro. The present investigation was carried out to show whether the hepatoprotective effect of the extract could also be manifested in vivo. Rats were given APE orally for 14 consecutive days, before being subjected to a single intraperitoneal injection of CCl 4 . One day after the CCl 4 injection, the animals were sacrificed, hepatocytes were isolated and liver homogenates were prepared for the assessment of liver injury. In isolated hepatocytes, APE afforded protection against CCl 4 -induced injury as manifested by a decrease in the leakage of the cytosolic enzyme lactate dehydrogenase (LDH), decreased generation of lipid peroxide and maintenance of cellular reduced glutathione (GSH) content. In principle, similar findings were observed in liver homogenates. The present findings show that APE has in vivo hepatoprotective potential which could be attributed at least in part to the maintenance of cellular GSH content. The latter effect seems to play an important role in conserving the integrity of biomembranes as it was associated with a decrease in lipid peroxidation and reduced leakage of cytosolic LDH.

Hepatoprotective effect of green propolis is related with antioxidant action in vivo and in vitro
Oxidants and Antioxidants in Medical Science, 2014
Objective: Propolis is a natural product produced by bees. In this study, the free radical scavenger and hepatoprotective activity of green propolis extract (G1) was investigated. Methods: In vitro experiments on guinea pig isolated trachea tissues and in vivo study on rat liver tissues were performed. Hepatic damage was induced by oral administration of carbon tetrachloride (CCl4) to rats. Hepatoprotective effect was monitored by histological analysis of neutrophil margination (NM) on liver, aspartate and alanine transaminases (AST, ALT), and gamma-glutamil transferase (γ-GT) activity. Results: Chemical constitution of G1 by high performance liquid chromatography analysis resulted in the presence of phenolic compounds. G1 produced a reduction of the relative activity of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. G1 also exhibited high superoxide radical and potent hydroxyl radical scavenging activity. On guinea pig isolated trachea tissues, G1 inhibited the superoxide radical-induced contraction in vitro. After CCl4 administration, AST, ALT and -GT activities were found to be increased; these levels were reduced with G1 treatment. Conclusion: Taken together, our results suggest a potent antioxidant effect of G1, related with hepatoprotective action on liver damage induced by CCl4.
Hepatoprotective and Pancreatoprotective Properties of the Ethanolic Extract of Nigerian Propolis
Journal of Intercultural Ethnopharmacology, 2015
The main types of flavonoids that have been reported include rutin (an antihypertensive agent), quercetin (a potent antidiabetic material), galangin and caffeic acid phenethyl ABSTRACT Objective: Increased oxidative stress is associated with the progression of diabetic mellitus. In the present study, we investigated the effects of the ethanolic extract of Nigerian propolis (N. propolis) on markers of oxidative stress, histology of the liver and pancreas and glycaemia in alloxan-induced diabetic rats. Materials and Methods: Alloxan-induced hyperglycemic Wistar rats were treated with either metformin (150 mg/kg/d) or N. propolis (200 mg/kg/d and 300 mg/kg/d) for 28 days. At the end of the treatment period, the rats were sacrificed; blood was collected for biochemical analysis while their pancreases and liver were excised and processed for histological studies. Results: Serum oxidative stress markers and blood glucose concentration were compared between the treated and control rats. In contrast to the non-treated diabetic rats, blood glucose concentration were not significantly different between treated rats and control (P < 0.05) at 28 days of treatment with N. propolis and metformin. Serum malondialdehyde levels was reduced while superoxide dismutase levels were elevated in the N. propolis group; these levels were converse in the diabetic group, these differences are statistically significant (P<0.05) when compared with the control. Histologically, there was improvement in the treated group compared to the untreated group. Conclusion: These findings suggest that the N. propolis confers protection against hyperglycemia-induced oxidative stress in both liver and pancreas of adult Wistar rats.

This study was planned to determine the effects of propolis in rats applied Cyclosporine A (CsA). In this study, 24 male Sprague-Dawley rats were used. Rats were randomly divided into 4 groups including control and 3 treatment groups. Group 1 (Control) were no supplement; CsA (group 2) were given as s.c. 15 mg/kg body weight (BW) every day; Propolis (group 3) were given by gavage 100 mg/kg BW every day; CsA+Propolis (group 4) were given as s.c. 15 mg/kg BW of CsA and by gavage 100 mg/kg BW of propolis every day. The feed intake were significantly higher (P<0.01) in Control and Propolis groups than CsA and CsA+Propolis groups within time period of 21 days. Further, body weight was significantly lower (P<0.01) in groups administrated with CsA (Group 2 and 4) than the other groups. Cortisol, AST, ALT and urea levels in serum of Control, Propolis and CsA+Propolis groups were found significantly lower (P<0.01) than those of CsA group. Malondialdehyde levels in kidney and liver tissues were significantly higher (P<0.01) than in the CsA groups compared to other groups. The catalase and reduced glutathione activities in kidney tissue of CsA+Propolis group were significantly higher (P<0.01) than those of CsA group. The present study demonstrated that propolis provided amelioration in terms of hepatotoxicity and nephrotoxicity consisting rats applied to CsA.
Effect of Croatian propolis on diabetic nephropathy and liver toxicity in mice
BMC Complementary and Alternative Medicine, 2012
Background: In the present study, we examined the antioxidant effect of water soluble derivative of propolis (WSDP) and ethanolic (EEP) extract of propolis on renal and liver function in alloxan-induced diabetic mice. In addition, we examined whether different extract of propolis could prevent diabetic nephropathy and liver toxicity by inhibiting lipid peroxidation in vivo. Methods: Diabetes was induced in Swiss albino mice with a single intravenous injection of alloxan (75 mg kg-1). Two days after alloxan injection, propolis preparations (50 mg kg-1 per day) were given intraperitoneally for 7 days in diabetic mice. Survival analysis and body weights as well as hematological and biochemical parameters were measured. The renal and liver oxidative stress marker malonaldehyde levels and histopathological changes were monitored in the liver and kidney of treated and control mice. Results: Administration of propolis to diabetic mice resulted in a significant increase of body weight, haematological and immunological parameters of blood as well as 100% survival of diabetic mice. Alloxan-injected mice showed a marked increase in oxidative stress in liver and kidney homogenate, as determined by lipid peroxidation. Histopathological observation of the liver sections of alloxan-induced diabetic mice showed several lesions including cellular vacuolization, cytoplasmic eosinophilia and lymphocyte infiltrations, but with individual variability.Treatment of diabetic mice with propolis extracts results in decreased number of vacuolized cells and degree of vacuolization; propolis treatment improve the impairment of fatty acid metabolism in diabetes. Renal histology showed corpuscular, tubular and interstitial changes in alloxan-induced diabetic mice. Test components did not improve renal histopathology in diabetic mice. Conclusions: Propolis preparations are able to attenuate diabetic hepatorenal damage, probably through its anti-oxidative action and its detoxification proccess as well as the potential to minimize the deleterious effects of free radicals on tissue. The protective role of propolis against the ROS induced damages in diabetic mice gives a hope that they may have similar protective action in humans.

Background: Propolis is a natural resinous combination that honeybees produce from the materials they gather from plant parts, buds, and exudates. Numerous favorable pharmacological qualities have been demonstrated for propolis. Objectives: This study aimed to investigate the hepatotoxic effects of ethanolic propolis extract on the liver of male rats. Methods: In this research, 40 male rats were divided randomly into five groups: 1. Control 2. Sham (solvent), and 3. Three experimental groups (ethanolic propolis extract at doses of 50,100 and 200 mg/kg). All materials were administered by oral gavage once daily for 13 consecutive days. On the 14th day, blood sampling was performed to measure serum levels of liver function enzymes and triglycerides. After deep induction of anesthesia, the liver of the rats was removed for histopathological studies. Data were analyzed using ANOVA and Tukey's test (p <0.05). Results: The data showed that the administration of propolis significantly increased the serum levels of aminotransferases in a dose-dependent manner and decreased triglycerides, accompanied by pathological changes.
