The effect of carbetox on glycolysis and the activity of some enzymes in carbohydrate metabolism in the fish and rat liver

Biochemical effects of two kinds of mineral oils and an IGR on adult female mealybug Ferrisia virgata (Cockerell)

“…Admiral caused a slight non significant decrease 4 days post treatment followed by a significant increase reached to 15.02% relative to the control. The general trend of suppressing Got activity in particular 10 days post treatment (except for Super Misrona oil),to a great extent, agreed with those effects reported for other insect species after treatment with different botanical and IGRs, such as T. castaneum (Tabassum, 1994;Tabassum et al, 1994), Alphitobium diaperinus (Tufail, 1991).This inhibitory effect observed in the present study , may be due to difficulty in the formation of dissociable enzyme-inhibtor complexes, which reduce the specific enzyme activity (Dragomirescu et al, 1979).On the other hand, the increase in GOT activity due treatment by Super Misrona oil present in this study may suggests the mobilization of amino acids during the insecticidal stress exerted by certain toxic components to meet the energy demands (Zeba and Khan, 1995).…”

Effects of Sublethal Doses of Fenvalerate (A Synthetic Pyrethroid) Administered Continuously for Four Weeks on the Blood, Liver, and Muscles of a Freshwater Fish, Ctenopharyngodon idella

“…The decreased hepatic LDH activity which could be due to enzyme inhibition, entails gearing up of Kreb's cycle and/or diversion towards gluconeogenesis, leading to hyperglycemic condition. A decrease in LDH activity has also been reported by Dragomirescu et al (1979) in the liver of Cyprinus carpio exposed to organophosphorus pesticide.…”

Animal Biomarkers as Pollution Indicators

“…Tinsley (1965) studied the effect of DDT in rats on the activity of two enzymes of the hexose monophosphate shunt. The organophosphate malathion decreased the activity of glucose-6-phosphatase in both the rat and the fish (Dragomirescu et al .• 1975). whereas the activity of 6-phosphogluconate dehydrogenase was not affected.…”
