Item Biochemical and morphological alterations caused by silver nanoparticles in wistar rats(Published by Elsevier. Journal of Acute Medicine, 2015-09-02) Sulaiman, F.A; Adeyemi, O.S; Akanji, M.A; Oloyede, H.O.B; Sulaiman, A.A; Olatunde, A; Hoseni, A.A; Olowolafe, Y.V; Nlebedim, R.N; Muritala, H; Nafiu, M.O; Salawu, M.OObjective: This study evaluated the biochemical effect of the oral administration of silver nanoparticles on some biochemical parameters and tissue morphology. Methods: Wistar rats of both sexes with an average weight of 160 ± 5 g were randomly assigned into four groups. Animals in Group 1 served as the control and received 0.5 mL of distilled water (drug vehicle). Those in Groups 2, 3, and 4 were administered with 10, 50, and 100 mg/kg body weight silver nanoparticles, respectively. The animals were sacrificed under slight anesthesia 24 hours after the last treatment. Results: Silver nanoparticle exposure in rats elevated the level of rat serum total cholesterol, triacylglyceride, free glycerol, low density lipoproteincholesterol, and bilirubin ( p < 0.05) when compared with the control. The level of high density lipoprotein-cholesterol was depleted by nanoparticle exposure, whereas the atherogenic index rose. The levels of albumin, urea, creatinine, as well as activities of aspartate transaminase and alkaline phosphatase were decreased by the nanoparticles, whereas the total protein and alanine transaminase were inconsistently altered relative to the control. Furthermore, the nanoparticle treatment caused morphological lesions in rat cardiac, renal, and hepatic tissues relative to the control. Conclusion: We show evidence that silver nanoparticle potentiated biochemical changes predisposing to liver injury and cardiovascular disorder in rat.Item Therapeutic properties and serum iron in T. brucei infected rats treated with amodiaquine and mefloquine(Published by Nigerian Society For Experimental Biology (NISEB)., 2005) Ekanem, J.T; Sulaiman, A.A; Adeyemi, OSerum iron was monitored in Trypanosoma brucei-infected rats treated with Amodiaquine and mefloquine antimalarials as the infection progressed. The chemotherapeutic properties of the drugs against African sleeping sickness were also assessed. Results show gradual reduction in the levels of serum iron in the infected but treated rats as the infection progressed. Results also show that reduction in serum iron level is more pronounced in amodiaquine treated but uninfected rats than the mefloquine treated rats. Serum level in infected but not treated rats increased steadily from the day of infection. For prophylactic treatments of infected rat, amodiaquine extended the lifespan of the rats for 14 days while mefloquine extended it for 7 days. For early stage treatment, amodiaquine and mefloquine extended life span for 7 and 4 days respectively while late stage treatment the extensions were 2 and 1 day respectively. Results suggest that these antimalarials especially amodiaquine could be useful in the clinical management of African sleeping sickness and that this may be through reduction of blood iron level, a situation that can inhibit ribonucleotide reductase of the proliferating parasites.
