Intoxication effects of lindane (γ-BHC) on the carbohydrate metabolism in the climbing perch, Anabas testudineus (Bloch)

Effects of an Acute Exposure to Lindane (γ-Hexachlorocyclohexane) on Brain and Liver Carbohydrate Metabolism of Rainbow Trout

“…This result is in agreement with data obtained previously by other authors in other species (Backthavathsalam and Reddy, 1983;Demael et al, 1987;Gill et al, 1991), which on the other hand is the common response found in fish after exposure to pesticides (Sastry et al, 1988;Gill et al, 1990). This increased level of glucose in plasma may be reflected in the metabolism of those tissues using exogenous glucose as a main fuel such as the brain (Washburn et al, 1992).…”

“…On the other hand, lindane is known to induce increases in hepatic detoxicant activities as well as increases in the activity of transaminases (Tusell et al, 1988), and therefore the activation of these processes may require an additional energetic demand in liver. Thus, in the present experiment, was found a clear decrease in liver glycogen levels of lindane-exposed fish, which is similar to those previously found by other authors after exposure to lindane (Backthavathsalam and Reddy, 1983;Ferrando and Andreu-Moliner, 1992), other organochlorines (Gill et al, 1991), or other pesticides (Sastry et al, 1988;Reddy and Yellamma, 1991;Sobha-Rani et al, 1991). This increased mobilization of liver glycogen is attributable to changes observed in the activity of those enzymes involved directly on its metabolism, i.e., GPase and GSase, since a clear increase in the percentage of GPase a as well as a clear decrease in the percentage of GSase a were oberved.…”

“…Lindane, the ␥-isomer of hexachlorocyclohexane (␥-HCH) is one of the most widely used organochlorine insecticides for agricultural purposes . Several physiological functions such as respiration, metabolism, and immunity are known to be inhibited by ␥-HCH during short-term intoxication (Srivastava and Mishra, 1982;Backthavathsalam and Reddy, 1983;Gluth and Hanke, 1985;Demael et al, 1987;Gill et al, 1991;Reddy et al, 1993). Among these physiological changes, energy metabolism has a key role as the animal is forced to spend more energy to mitigate toxic stress (Ferrando and Andreu-Moliner, 1992), which is related to the increased oxygen consumption already reported in fish tissues after organochlorine exposure (Sastry et al, 1991).…”

Comparison of physicochemical properties of different tissues from China climbing perch Anabas testudineus and crucian carp Carassius auratus

“…At present, the qualitative of amino acids showed the predominant essential amino acids in climbing perch and crucian carp eggs were arginine, lysine, leucine, and valine, indicating that there is a certain particular profile in the essential amino acids of freshwater fish eggs, making them to inhabit and reproduce in freshwater. In addition, one feature of climbing perch is its ability to utilize liver glycogen to build up muscle glycogen and blood glucose under lindane intoxication (Bakthavathsalam & Reddy, 1983 ), which explained why more sugar was contained in climbing perch liver (Figure 1d ). Further the accumulation of sugar in climbing perch liver might be stored as energy source against poor environment.…”

Biochemical Analysis to Study the Nutritive Value of the Fish Catla Catla after Exposure to the Phytotoxin from Lasiophion Eriocephalus

“…According to Reference [19] carbohydrate represents immediate and principal energy source for fishes exposed to stress conditions. Reference [3] reported that glycogen is utilized for energy production to meet higher energy demands to counteract pesticide stress.…”
