Propolis, a resinous material produced by worker bees from the leaf buds and exudates of plants, is reported to possess various therapeutic properties. The aim of this study was to investigate the effects of propolis on biochemical parameters and histopathologic findings in carp Cyprinus carpio L. exposed to arsenic. A sublethal concentration of arsenic (0.01 mg l −1 ) and/or 10 mg l −1 propolis were administered to fish for 1 wk. Catalase (CAT) activities and malondialdehyde (MDA) levels were determined in liver, gill and muscle tissues in control, arsenic only, propolis only and arsenic+propolis treatment groups. Results showed that CAT activity decreased in the arsenic group compared to the control and propolis groups. CAT activity in the arsenic+ propolis group was significantly higher compared to the arsenic group. MDA levels in fish exposed to 0.01 mg l −1 arsenic significantly increased compared to the control group. However, MDA levels in the arsenic+propolis group were significantly lower compared to the arsenic group. Histopathological changes in the liver, gill and muscle tissues of carp were examined by light microscopy: various changes were observed in all tissues of fish in the arsenic group. Propolis showed important antioxidant effects against arsenic toxicity in all fish tissues.
Effects of propolis on some blood parameters and enzymes in carp exposed to arsenic
Iranian Journal of Fisheries Sciences
The purpose of this study was to investigate the therapeutic effects of natural products like propolis on biochemical and hematologic parameters in carp (Cyprinus carpio, Linnaeus 1758) exposed to arsenic. In this study fish were exposed to 0.01 mg/L arsenic and 10 mg/L propolis for seven days. Our results indicated that triglyceride, urea, total cholesterol, cobalt, ALT (alanine amino transferase), AST (aspartate amino transferase), LDH (lactate dehydrogenase) values increased when exposed to arsenic (P<0.05) but reduced by combination of arsenic and propolis (P<0.05). Granulocyte, erythrocyte, hemoglobin, hematocrit values were decreased by use of arsenic in comparison to control group. These parameters increased in arsenic+propolis group (P<0.05). In addition levels of leucocyte, agranulocyte, MCV (mean corpuscular volume), MCH (mean corpuscular hemoglobin) and MCHC (mean corpuscular hemoglobin concentration) increased in the arsenic group (P<0.05) and decreased in arsenic+propolis group (P<0.05). We can say that propolis can improve biochemical and hematologic functions of common carp blood, after being exposed to arsenic.

The purpose of this study was to investigate the therapeutic effects of propolis on biochemical and microbiological parameters in muscle tissues of carp (Cyprinus carpio, Linnaeus 1758) exposed to arsenic. A sublethal concentration of arsenic (0.01 ppm) and/or 0.01 ppm propolis were administered to fish for seven days. Biochemical parameters [pH, lactic acid, total volatile basic nitrogen (TVB-N), and malondialdehyde (MDA) values] and microbiological changes (mesophilic and psychrophilic bacteria count) were determined in fillet of carp in control, arsenic only, propolis only and arsenic+propolis treatment groups. Results showed that the levels of MDA, lactic acid and TVB-N increased (p<0.05) while there were decreases total counts of psychrophilic, mesophilic bacteria and level of pH in arsenic group compared to the control group. Additionally, levels of pH, lactic acid, TVB-N, counts of psychrophilic and mesophilic bacteria in arsenic (0.01 ppm)+propolis (10 ppm) group signific...

The effect of arsenic bioaccumulation in liver, kidney, skin, muscle, and intestinal tissues of mirror carp (Cyprinus carpio carpio) was investigated on lipid peroxidation and certain antioxidant enzyme activities. In this study, three aquarium groups were formed from mirror carp: control group, 0.5-, and 1-mg/L arsenic concentrations. The fish were dissected after 1 month. Arsenic bioaccumulation, malondialdehyde (MDA) levels, catalase (CAT), and superoxide dismutase (SOD) enzyme activities were determined in the tissues. Results showed that arsenic was accumulated in liver, kidney, muscle, skin, and intestinal tissues. As the final product of lipid peroxidation, MDA levels were determined to have increased in all tissues with the exception of muscle. On the other hand, CAT and SOD enzyme activities in the fish tissues were decreased as compared to the control group. In the muscle tissue, differences were observed in the enzyme activities depending on arsenic concentration. Considering the increases in enzyme inhibition and MDA levels, liver was observed to be the main tissue affected in response to the arsenic toxicity.
Antioxidant effect of propolis against exposure to chromium in Cyprinus carpio
Environmental toxicology, 2014
The aim of the present study was to investigate the ameliorative properties of propolis against the toxic effects of chromium (VI) by examining oxidative damage markers such as lipid peroxidation and the antioxidant defence system components in carp (Cyprinus carpio). The fish were exposed to sublethal concentrations of chromium. Propolis was simultaneously administered to chromium-exposed fish. Treatment was continued for 28 days, and at the end of this period, blood and tissue (liver, kidney, spleen, and gill) samples were collected. Levels of malondialdehyde (MDA) and reduced glutathione (GSH) as well as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were determined in blood and tissues for measurement of oxidant-antioxidant status. The levels of MDA, as an index of lipid peroxidation, increased in blood and tissues. Antioxidant enzyme activities in blood and tissues were modified in chromium groups compared to controls. Simultaneous ad...

The biochemical toxicity of arsenic trioxide (As III ) in a freshwater edible fish Channa punctatus has been studied on exposures ranging from 7 to 90 d. The arsenic concentration increased exponentially in liver, kidney, gills, and muscles of fish up to 60 d of exposure to arsenic. However, arsenic concentration in these tissues declined at 90 d of exposure. This relationship between period of exposure and concentration of arsenic in selected tissues suggests an adaptive response of fish to arsenic. Furthermore, exposure to arsenic-induced lipid peroxidation in these organs increased initially at 7 d of exposure; however, it decreased up to 60 d of exposure but increased again at 90 d of treatment. Values of reduced glutathione (GSH) reflected the observations of lipid peroxidation. The role of GSH in this adaptive response has been discussed.
The present study investigated the comparative effect of Cadmium and Arsenic on the activities of brain sulphite oxidase and aldehyde oxidase in the African cat fish (clarias gariepienius) after 35 days, with the aim of determining the metal that has a stronger effect on drug metabolizing enzymes. The research employed three groups of 0.1 mg/L., 0.2 mg/L and 0.4 mg/L per metal respectively and one control group. No significant difference was observed on the activities of both enzymes in the brain of the fishes exposed to both metals (P>0.05). However, there was a significant increase on the activities of the enzymes. The research concludes that both metals are toxic in aquatic environments and that arsenic is less toxic in this environment with reference to the concentrations they were exposed.

The possible role of glutathione-dependent enzymes in the liver and kidney of the freshwater fish Channa punctatus has been studied after exposure to arsenic trioxide for different durations. Activities of glutathione-Stransferases, glutathione peroxidase, glutathione reductase, and catalase decreased in the liver and kidney as a result of the initial increase in arsenic concentration in the liver and kidney. However, during longer exposures, a decline in arsenic concentration corresponded with improved enzyme activity. Because arsenic manifests its toxicity by inducing oxidative stress, the antioxidant enzymes, especially the glutathione-dependent enzymes, play a protective role in arsenic toxicity.
