“…Protein exhaustion in tissues might comprise a physiological component and may assume a part of compensatory system under cyphenothrin stress, to give intermediates to the Kreb's cycle. It has likewise been accounted for that this pattern of proteins was to upgrade osmolality to remunerate osmoregulatory issues experienced because of the spillage of ions and other required molecules during pyrethroid effects (Rafat Yasmees 1986).…”

Pyrethroids are used in almost all agricultural crops, nurseries, various urban structural and landscaping sites, construction sites (pre-construction termiticides), the pyrethroids is their efficacy against a broad range of insects, pests and mites, low mammalian and avian toxicity, low potential to contaminate ground water, and relatively low application rates like several desirable characters to contribute. Cyphenothrin is the synthetic pyrethroid insecticide widely used throughout the world to control domestic pests, public health and industrial location. Cyphenothrin is more toxic to insects and mammals and last longer in the environment. Freshwater fish, Cirrihinus mrigala were exposed to sublethal concentration one fifth of LC 50 30 g/L (6 g/L) of cyphenothrin for 10, 20, 30 and 40 days to analyze various parameters of protein metabolism in functionally different tissues. Total, structural and soluble proteins showed decrease; whereas free amino acids and the activities of protease, aspartate aminotransferase and alanine aminotransferase significantly increased in cyphenothrin exposed fish. Interestingly, ammonia content decreased but urea and glutamine increased at all periods of exposure. It was also observed that alterations steadily increased with the period of exposure and exhibited tissue specificity. Thus variation in the protein metabolism of the fish exposed to cyphenothrin indicates its toxic effect on the cellular metabolism thereby leading to impaired protein synthetic machinery.

Ranjeet et al.: Effect of Ekalux toxicity on selected physiological parameters in Anabas testudineusAbstract. Impact of short-term exposure of sub lethal concentration of organophosphate pesticides Ekalux on physiology of sub adults of Anabas testudineus in the Kol paddy fields of Central Kerala was studied. Results of the present study indicated that even short-term, exposure to Ekalux is detrimental to A. testudineus. Among the parameters that showed significant changes were heamatological parameters such as Hb, PCV, RBC count, and ESR. Cell morphology shifted from a normal elliptical shape after 24 hr to crenated or fringed and shrinked appearance at 15 th day of exposure. It was also seen that protein and amino acid concentration are clear indicators of immediate stress. Histopathological studies of liver showed hypertrophied hepatocytes with reduced number of normal cells after 15 days of exposure. The number of haematopoietic tissue was found to have declined in the kidney also in addition to increased number of melano-macrophage centres (MMC). However, once these fishes were reared in clear water, devoid of any pesticide for six months, values for Hb, PCV, protein, amino acid and liver and renal tissues showed signs of revival. The present study depicts that severity of Ekalux toxicity to sub adults of Anabas testudineus is both dose and time dependant.
