Excess aluminum (Al) in soils due to acid rain leaching is toxic to water resources and harmful to soil organisms and plants. This study investigated adverse impacts of Al levels upon earthworms (Eisenia fetida) from the latosol (acidic red soil). Laboratory experiments were performed to examine the survival and avoidance of earthworms from high Al concentrations and investigate the response of...

Therapeutic alternatives are needed against infections caused by highly multidrug-resistant Streptococcus pneumoniae. Novobiocin, an old antibiotic, was tested in vitro and in a murine sepsis model against one amoxicillin-susceptible and three amoxicillin-resistant strains [minimum inhibitory concentrations (MICs) 8-64 mg/L]. Novobiocin MICs for all strains were 0.25-0.5 mg/L. In sepsis, novobi...

In the present work, the antinociceptive action was assayed in several experimental models in mice: writhing, formalin and hot plate tests.

Antitubercular drug induced hepatotoxicity is a major hurdle for an effective treatment of tuberculosis. The present study was undertaken to assess the hepatoprotective potential of tocopherol (50 mg/kg and 100 mg/kg, ip) and to compare it with cimetidine (120 mg/kg, ip). Hepatotoxicity was produced by giving isoniazid (INH, 50 mg/kg, po) and rifampicin (RMP, 100 mg/kg, po) combination to albin...

The effect of varying doses of cimetidine and omeprazole, on acute gastric mucosal lesions produced by topical aspirin (200 mg/kg; 1 ml/100 g) in 0.175 M HCl or topical sodium taurocholate (40 mM; 1 ml/100 g) in 0.175 M HCl was studied in the pylorus ligated rat. Preliminary studies revealed dose dependent inhibition of acid secretion with both cimetidine and omeprazole. Intraperitoneal cimetid...

The objective of this experimental study was to examine the pathological effects of the intramuscular administration of gentamicin to growing chickens. Two experiments of 35 days’ duration were conducted simultaneously. In both experiments White Leghorn cockerels of 6 weeks of age were randomly divided into 4 groups and gentamicin was administered intramuscularly to the birds on days 1 and 3 at...

Telfairia occidentalis Hook. f., Cucurbitaceae, is a leafy vegetable used in soup and folk medicine in southern Nigeria. This study was conducted to investigate the anxiolytic and sedative activities of the hydroethanolic extract of the leaves of T. occidentalis in mice. The hole-board, elevated plus maze, open-field, light-dark, and social interaction tests were used in this study. T. occident...
