Animals were tested in same-sex pairs in an open field for time spent in contact and for socially facilitated activity. The liver, kidneys, and brain are considered to be the target organs for the toxic effects of lead (Sharma and Street, 1980; Jackie et al, 2011). Brown rats are now found on every continent except Antarctica. They are reared and bred chiefly for use in the laboratories or as pets. All animals were kept free of pathogenic microorganisms, with the absence of surgical interventions that could cause anatomical and physiological changes. Toxicity of lead is mainly attributed to the induction of oxidative stress by elevation of reactive oxygen species (ROS) such as Colonies varied in size from four to twenty rats, and were usually maintained for at least nine weeks. 2018b), red-tailed hawks (Buteo jamaicensis), coyotes (Canis latrans) and red foxes (Vulpesvulpes). Laboratory rats, like many other animal species, transport food. The organ-systems of guinea pig are almost similar to those of rats, so far requirements of routine dissection are concerned. Animal material consisted of albino rats of Wistar strain (Rattus norvegicus) of different body weight according to age.These rats had free access to water, food and acclimatized to conditions of animal husbandry of the Laboratory of Physiology, Pharmacology and Pharmacopoeia (L3P) of Nangui Abrogoua University (Abidjan/Cote d 'Ivory).
