Toxicological effects will occur when the metal ion reaches a critical target within the body and the defence and repair mechanisms of the cells are exceeded. One of the mechanisms of protection the cell may employ against metal ion toxicity is the formation of nontoxic metal–protein complexes with various proteins such as metallothioneins.As nouns the difference between pharmacology and toxicology is that pharmacology is the science that studies the effects of chemical compounds on living animals, especially the science of the manufacture, use and effects of medicinal drugs while toxicology is the branch of pharmacology that deals with the nature, effect, detection and treatment of poisons and poisoning.Pharmacology is the study of drugs. It involves examining the interactions of chemical substances with living systems, with a view to understanding the properties of drugs and their actions, including the interactions between drug molecules and drug receptors and how these interactions elicit an effect. Programs in pharmacology are offered by ... The evaluation of combination effects between biological or chemical agents plays a significant role in pharmacology and biomedicine. Combination therapies, often referred to as “cocktail” therapies have revolutionized patient outcomes in diseases such as HIV [ 1 ], asthma[ 21 ], breast cancer [ 6 , 20 ], hypertension [ 13 ], and cancers ...
