Albino and hooded male rats were administered 14C-labeled 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) by gavage. The tissue distribution was investigated by means of whole-body autoradiography and liquid scintillation counting. MeIQx was rapidly absorbed from the alimentary tract and distributed to several tissues. The major predilection sites were the liver and kidneys. The amount of radioactivity decreased dramatically within a few days. However, unextractable radioactive material was still detectable in these organs 6 days after the administration.

D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

D014018 Tissue Distribution Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios. Distribution, Tissue,Distributions, Tissue,Tissue Distributions
