The protective role of 3-aminothiazolo[3-2a]benzimadzole-2-carbonitrile against lung and colon injury induced by nitrosomorpholine in adult male albino rat

Nitrites and morpholine are ubiquitous environmental contaminants found in drinking water and food. NMOR can be formed endogenously from nitrite and morpholine. Increased levels of reactive oxygen species/ reactive nitrite species (ROS/RNS) are involved in the mechanism of NMOR toxicity. Certain antimicrobial, antifungal and antioxidant potential were observed in heterocyclic benzimidazole derivatives and dimethyl...

Modulatory effects of kolaviron (Garcinia kola extract) on spermogram and reproductive system of adult male wistar rats in lead acetate induced toxiocity

This study was designed to determine the effects of the concomitant administration of kolaviron (Garcinia kola extract) with lead on male fertility by evaluating some spermogram and histopathology of the testis. 20 adult male Wistar rats were randomly divided into 4 groups of 5 rats each. The rats in group O (negative control) were given normal saline, while rats in group A were given 6 mg/kg body weight of lead...

Metals bioavailability in the leachates from dumpsites in Zaria Metropolis, Nigeria

Landfill leachates pose a significant threat to both surface water and groundwater especially the wells adjacent to landfills. The study investigated the bioavailability of zinc (Zn), copper (Cu), lead (Pb), cadmium (Cd) and mercury (Hg) from leachates of ten huge dumpsites across the metropolitan city of Zaria. The trends in the mean concentrations of the metals (mg/L) among the fractions were; Zn: total > mobile...
