    Heavy metal contamination of clarias gariepinus from a lake and fish farm in Ibadan, Nigeria
    (Ibadan Biomedical Communications Group, 2004) Olaifa, F. E.; Olaifa, A. K.; Adelaja, A. A.; Owolabi, A. G.
    Adult Clarias gariepinus (African Catfish) were purchased from Eleiyele Lake and Zartech fish farm in Ibadan. Water samples were also collected in February (dry season) and June (rainy season), 2002. Gill, bone, intestine, muscle and water samples were analyzed for five metals: manganese, copper, zinc, iron, and chromium by atomic absorption spectroscopy (AAS) in two separate experiments. In each case, two tissues were compared with the levels of the metals in water viz: Gill, bone, and water; intestine, muscle and water. Generally, lower concentrations of the metals were recorded in water than fish tissues. Higher concentrations of zinc than recommended by the Federal Environmental Protection Agency were recorded in the fish during the dry season. Iron was the dominant metal in the muscle while Chromium was the least. Significant differences (p<0.05) were recorded in copper and zinc concentrations in the muscle, intestine and water during the dry and rainy seasons .In gill, bones and water, significant differences (p<0.05) were only recorded for the two stations for copper during the rainy season and only zinc was significantly different (p<0.05) in the dry season. It was concluded that though the heavy metals of interest were present in measurable quantities there were still within safe limits for consumption

    Urbanization and symptomatic malaria in relation to retroviral screening
    (2008) Adeoti, O. M.; Anumudu, C. I.; Olaniyan, M. F.; Adejumobi, C. A.; Ajifowobaje, C. O.; Owolabi, A. G.; Hammed, O.
    A descriptive cross-section analysis of five hundred patients who were symptomatically diagnosed of malaria in three locations: Saki (peri-urban), Ibadan (urban) and Lagos (highly urbanized) were recruited for this study using a well structured questionnaire between September 2005 and June 2006. The prevalence of both malaria and HIV infections were higher in Peri-Urban town than the other two locations. We observed that 80% were HIV positive in Saki. 20% in Ibadan and 37.1 % in Lagos. Our data indicated that 74% were malaria positive in Saki, 87% in Lagos and 24% in Ibadan. The percentage of co-infection in Saki, Logos and Ibadan were 69%, 16% and 14.3% respectively. The high prevalence of coinfection in the two cross-border locations (Saki and Lagos) is suggestive of a high correlation between clinical symptomatic malaria and HIV infection with respect to cross border transmission of the two infections . This paper suggests that government should make provision to establish sentinels for screening immigrants.
