Response to stress is well documented in many different biological systems . A common feature of this response at the molecular level is the induction of suite of proteins , which were first name "heat -stock proteins (HSPs)" as they were first discovered in cells exposed to hyperthermia ,or heat stock. The heat stock response to molecular stress response ,as it is popular currently , is one of the most conserved stress responses of biological system; all organism ranging from bacteria to mammals as higher plants, display molecular stress response by way of induction of a remarkably homologous set of proteins in response to different stressors. These proteins are involved in the protection, enhanced survival and restoration of the normal activities of the cells. HSPs are able to bind to denatured or unfolded proteins there by providing cytoprotective benefits to cells so that it may better cope up with stress. Stress proteins and their constitutively expressed congants play crucial roles in modulating proteins to proteins interactions. Many stress proteins seem to function as molecular chaperons by regulating protein folding. A persual of literature (Abidi, 1990;Bauman et al.1993 and Burdon, 1988 idicates that our information regarding the effect of disyston (organophosphate) and lindane (organochlorine) on changes in stress protein profiles of selected tissues (gills, liver and muscle) in freshwater teleost is very limited as such the present work has been taken into account in a freshwater mud dwelling teleostean eel fish, Macrognathus aculeatum (Lac).
