As part of a survey of fish diseases, lake whitefish (Coregonus clupeaformis) were collected in fall 1995 from the St. Lawrence River 15 km upstream of Quebec City, Quebec, Canada, to assess the prevalence of liver lesions. A total of 141 fish were captured and necropsied, and three standard sections of liver were taken for histological examination. Prevalences of altered hepatocyte foci, hepat...

an experiment was conducted on broiler chickens to study the effects of conjugated linoleic acid (cla), fish oil, both at 7% of the diet, or their mixtures at 3.5% of the diet, on the performance, carcass traits and intestinal morphology of broiler chickens. the chicks fed with 7% fish oil or 7% cla diets, were found to have an inferior weight gain in grower and finisher phases, respectively. a...

Opisthorchiasis is a health problem in rural communities of Thailand, particularly in the northeast and north regions. Therefore, this study aimed to investigate raw fish consuming behavior related to liver fluke infection among the population at risk for opisthorchiasis and cholangiocarcinoma (CCA). A cross-sectional descriptive study was conducted in Meuang Yang district, Nakhon Ratchasima pr...

Aim: Three species of fish, Notoptrus notoptrus, Channa punctatus and Glossogobius giuris, were shown to accumulate heavy metals like Zn,Fe,Ni,Pb,Cd, Cu in their gut-free bodies, liver, gills. Methodology: These fish inhabit the Kapila River Nanjangud area Mysore district. Result: Fish tissues (muscle, gills liver) sediments found contain Fe, Pb, Ni, Zn pollution. It was also determined that th...

In this research, in order to observe the seasonal change between April 2014 and February 2015, heavy metal contents water, sediment Carassius gibelio (Bloch, 1782) tissues (muscle, gill liver) growing Eber Lake were determined. The obtained results showed that trace elements founded fish tissues. Among average annual concentrations of water samples, highest concentration was found for Mn (0.15...

Knowledge of Hg speciation in tissue is valuable for assessing potential toxicological effects in fish. Direct Hg analyzers, which use thermal decomposition and atomic absorption spectrometry, have recently gained popularity for determining organic Hg after procedural solvent extraction from some environmental media, although quantitative recovery from lipid-rich materials, such as fish liver, ...

Cod-liver oil has been used as a household remedy for centuries and over the course of time scientific explanations for its properties have become available. The first extensive clinical tests of cod-liver oil seem to have been made by Samuel Kay, a physician at the Manchester Infirmary from 1752 to 1784. He gave doses of cod-liver oil to patients suffering from bone diseases and rheumatism and...

Four overlapping cDNA fragments encoding a partial sequence for uncoupling protein 2 (UCP2) were amplified by PCR using degenerate primers from the liver of a marine teleost fish, red sea bream (Pagrus major). The partial sequence was 674 bp long, encoding 224 amino acids. The deduced amino acid sequence from the cDNA partial sequence contained the signature motifs for mitochondrial transporter...

Accumulation of nickel, lead, copper and zinc in the liver of a freshwater fish, Tor putitora has been studied from polluted waters of River Kabul at two different sites and compared with those from pristine Warsak Dam reservoir upstream of polluted part of the River Kabul. The liver of fish from polluted site showed higher concentration of zinc (1300% and 3100%), nickel (21.1% and 25.5%), lead...
