“…The histological observation revealed that MMC and Na 2 SeO 3 treatment had comparatively overt bad effects on medaka gills. Similar reports have been exemplified in previous reports (Karan et al, 1998;Peuranen et al, 2003).…”

Interaction of methylmercury and selenium in medaka (Oryzias latipes) on bioaccumulation of pollutants and histopathological changes in liver and gill were studied. Juvenile medaka fish were submitted to a series of waterborne methylmercury chloride (MMC), sodium selenite (Na 2 SeO 3 ) and their mixture for 210 days, respectively. The methylmercury (MeHg) and selenium contents in the whole body of medaka were determined. The dose-and time-dependent increase of MeHg and selenium contents in medaka were observed. Histopathological changes, such as edema, vacuoles, pyknotic nucleus, and telangiectasis, could clearly be observed in the slices from the exposed medaka's liver and gill. Concurrent exposure to MMC and Na 2 SeO 3 showed the increased selenium accumulation. When the exposure molar ratio of MeHg:Se was about 1, the interaction between MeHg and selenium offered a limited protection against the serious intoxication of both MMC and Na 2 SeO 3 to medaka. # 2007 Wiley Periodicals, Inc.

“…These gill histological alterations has been observed by several authors in fish submitted to copper (Karan et al 1998, Chen & Lin 2001, De Boeck et al 2001. However, these changes also can be due to the exposition to different kinds of pollutants, such as endosulfan (Nowak 1992), arsenic (Hwang & Tsai 1993), drugs (Schwaiger et al 2004) and other T T T T heavy metals, as aluminium (Karlsson-Norggren et al 1986), cadmium (Reid & McDonald 1988), and nickel (Pane et al 2004).…”

Histopathological changes in liver and gill epithelium of Nile tilapia, Oreochromis niloticus, exposed to waterborne copper

et al. 2007

Nile tilapia, Oreochromis niloticus, of both sexes were reared in freshwater and exposed to 0.5, 1.0 and 2.5mg L-1 of waterborne copper for a period of 21 days. Liver and gill samples were collected after 21 days of exposure to copper and lesions were analyzed by light microscopy. The main histopathological changes observed in gills exposed to the highest concentration were edema, lifting of lamellar epithelia and an intense vasodilatation of the lamellar vascular axis. Although less frequent, lamellar fusion caused by the filamentar epithelium proliferation and some lamellar aneurisms were also found. The liver of control group exhibited a quite normal architecture, while the fish exposed to copper showed vacuolation and necrosis. These hepatic alterations were more evident in fish exposed to 1.0 and 2.5mg L-1 copper concentrations. The number of hepatocytes nucleus per mm² of hepatic tissue decreased with the increase of copper concentration. In contrast, the hepatic somatic index was high in fish exposed at 2.5mg L-1 of copper. In short, this work advance new knowledge as influence of copper in the gill and liver histology of O. niloticus and demonstrated that their effects could be observed at different concentrations.

“…According to Machado and Fanta (2003) the cell proliferation in the interlamelar region reduces the respiratory surface and makes gaseous exchanges more difficult. Fusion of secondary lamellae that was observed in the gills of the P. mesopotamicus resulted in an even higher reduction of the total respiratory area of the gills, and as a result, there was a reduction of the capacity of oxygen capture, causing hypoxia (Ojha et al, 1989;Karan et al, 1998). Fusion of secondary lamellae was equally observed in gills of Lepomis macrochirus after 72 h of exposure to the OP malathion (Richmonds and Dutta, 1989), as well as in fishes contaminated with metals such as mercury (Oliveira Ribeiro et al, 1996), copper (Arellano et al, 1999), or cadmium (Thophon et al, 2003).…”

“…Histological alterations constitute excellent biomarkers of exposure to toxicants because they represent the result of biochemical and physiological changes (Hinton et al, 1989). The most common injuries in gills are epithelial detachment (Machado and Fanta, 2003;Mallatt, 1985;Richmonds and Dutta, 1989;Schwaiger et al, 2004), hyperplasia (Annune and Ajike, 1999;Dutta et al, 1993;Fanta et al, 2003;Oliveira Ribeiro et al, 1996), fusion of secondary lamellae (Capinpin, 1994;Karan et al, 1998;Thophon et al, 2003) and aneurysm (Stentiford et al, 2003;Thophon et al, 2003;Van den Heuvel et al, 2000). Piaractus mesopotamicus is a freshwater native fish from tropical and subtropical rivers of the Paraná-Paraguay Basin and from flooded areas of the Pantanal region (State of Mato Grosso, Brazil) (Severi et al, 1997;Lima et al, 1998).…”
