“…The alterations in the glucose level might be related to liver damage, renal injury, lack of nutrition and synthesis of glucose from extra hepatic tissue proteins and amino acids (Öner et al, 2008). In addition, chemical contaminants modulate the carbohydrate metabolism, resulting in hyperglycemia by stimulating the glycogenolysis in fish (Levesque et al, 2002;Osman et al, 2010).…”

Key words:Biochemical; Histopathology; Oreochromis niloticus; Lake EdkuThe main objective of this study is to assess some biochemical and histopathological changes in Nile Tilapia, Oreochromis niloticus caught from Lake Edku. A decrease in serum total protein, albumin, total lipids, bactericidal activity, ALT and AST was observed in El-Maadyah and Edku drain regions compared to recovery group, while the levels of serum glucose and lysozyme activity were increased. The frequencies of micronucleus (MN) and nuclear abnormalities (NAs) in fish erythrocytes showed an increase of micronuclei, lobed nuclei and fragmented apoptotic nuclei while notched nuclei were decreased. Finally, the frequencies of morphologically altered erythrocytes (MAEs) of fish showed an increase in swelled cells, vacuolated cytoplasm; microcytes; echinocytes; teardrop like; sickle cells and nuclear retraction. On the other hand, the main prominent hepatic lesions were parasitic granuloma, encapsulated parasitic cysts by connective tissue, fatty degeneration, congestion and necrosis. The histopathological analysis of muscle sections of both polluted sites showed edema, splitting of muscle fibers, hyalinized muscle fibers, fatty tissue, necrosis and infiltration of lymphocytes. From the above, we can conclude that the contaminated environment of fish could cause detrimental effects on fish tissues and immune system causing great economic losses for the natural resources.

“…Kock et al (1996) reported that fish respond to oxidative stress by increasing or decreasing certain biochemical compounds including enzymes. Alterations in these biochemical biomarkers are frequently used as an indicator of the general state of health and early warning of stress in fish under stressful condition (Abou El-Naga et al, 2005;Osman et al, 2010). Enzymes used as biomarkers in this study are GST, CAT and SOD and there were alterations in their activities in the gills, liver,muscle and fin following exposure to multivitamins production effluent.…”

The potential toxicity of multivitamins production effluent sourced from the discharge point of a pharmaceutical industry in Kwara State, Nigera was investigated using Clarias gariepinus. The growth performance, biochemistry of alterations and histopathological lesions in tissues and organs of post juvenile Clarias gariepinus was also analyzed. The impact of long term exposure to the effluent was evaluated using 0, 2, 4, 6, 8 and 10 % concentrations of the effluent for 21 days, following a range finding test. C. gariepinus exposed to sub-lethal concentrations of effluent showed increased growth performance and nutrient utilization at the 10% effluent concentration. Biochemical studies carried out on the gill, fin, liver and muscle showed that activities of anti-oxidative stress enzymes, Superoxide Dismutase (SOD), Catalase (CAT), and Glutathione-S-Transferase (GST), were higher in the liver of the effluent exposed C. gariepinus when compared to other tissues. Behavioural changes observed in fish exposed to all concentration of the effluent and control was normal. Histopathological examination of C. gariepinus exposed to sub-lethal concentrations of the effluent showed severe degenerating changes in liver and gills than muscles and fin. In this study, the effluent had pronounced effect on the growth and enzymatic activities of studied tissues and organs of C. gariepinus. Conclusively, this study revealed that the multivitamins production effluent, although treated is still a potent contaminant to post juvenile C. gariepinus.

“…Among the biochemical profiles, monitoring of liver enzymes leakage into the blood has proved to be a very useful tool in liver toxicological studies (Osman et al, 2010). The transaminase, GPT and GOT are two key enzymes considered as a sensitive measure to evaluate hepatocellular damage and some hepatic diseases (Ibrahim and Mahmoud, 2005).…”
