Jl. Soengas et al., EFFECTS OF AN ACUTE EXPOSURE TO LINDANE (GAMMA-HEXACHLOROCYCLOHEXANE)ON BRAIN AND LIVER CARBOHYDRATE-METABOLISM OF RAINBOW-TROUT, Ecotoxicology and environmental safety, 38(2), 1997, pp. 99-107
The capacity of carbohydrate and ketone bodies metabolism in brain and
liver was evaluated in rainbow trout control and exposed to lindane (
0.05 mg.L-1) for 12 hr. The results obtained demonstrate the existence
of changes in several parameters of brain carbohydrate metabolism due
to lindane treatment. Thus, increased plasma glucose levels are refle
cted in brain by the mobilization of glycogen stores and increased lac
tate levels probably reflecting an increased anaerobic use. Also, keto
ne bodies appear to be used under this stressful condition. In liver,
the main results obtained suggest that glycogen stores are being mobil
ized to be probably used as glucose in pathways other than glycolysis.
