Abstract
Addition of NaF or MFP to rat hepatocytes resulted in a decrease in lactate and in an increase in glucose, 3 and 2-phosphoglycerate production. When dihydroxyacetone was present in the incubation medium both NaF and MFP increased the production of glucose, fructose-1,6-diphosphate, 3 and 2 phosphoglycerate, with a decrease in pyruvate and lactate. In the presence of lactate, glucose production increased only in the presence of MFP, but there was a 8–10 fold increase in the level of phosphoenol pyruvate with both NaF and MFP. The crossover data indicated that the activity of some of the glycolytic enzymes may be inhibited in the presence of NaF and MFP.

Influence of extended exposure to sodium fluoride and caffeine on the activity of carbohydrate metabolism enzymes in rat blood serum and liver.
A 50-day study of the influence of fluoride (F) and caffeine on carbohydrate metabolism enzymes was conducted on 18 male Sprague-Dawley rats, 4.5 months old, housed in separate cages at 22–25°C on a 12-hr light/dark cycle. The rats were divided into three groups with six rats in each group: control,

Ameliorative effect of tamarind leaf on fluoride-induced metabolic alterations
OBJECTIVES: Fluoride is a serious health hazard across several nations, and chronic intake of fluoride deranges the carbohydrate, lipid and antioxidant metabolism in general. As there are limited remedial measures to prevent fluorosis, we investigated the role of tamarind leaf as a food supplement in restoration of carbohydrate, lipid and

Gluconeogenesis and glycogenolysis in fluoride-treated rats.
Intraperitonial administration of 10 mg fluoride (NaF)/kg body weight resulted in hyperglycemia in rats. Role of gluconeogenesis and glycogenolysis in this hyperglycemic response was evaluated. Results of the study indicate that the fluoride induced hyperglycemia is mainly due to increased hepatic glycogenolysis.

Red blood cell glucose metabolism in human chronic fluoride toxicity
Fluoride is a well known inhibitor of many enzyme systems in vitro (Shahed etal. 1979; Messer 1984). The most widely studied classic example of fluoride inhibition is its potent inhibition of glycolysis, specifically its action on the enzyme enolase (Warburg and Christian 1941; Shearer and Suttie 1970; Repaske and Suttie

The influence of fluoride ions upon selected enzymes of protein metabolism in blood plasma of rabbits with hypercholesterolemia
Three-month studies were performed on 18 adult rabbits of New Zealand breed divided into three groups, with six animals in each: a control group on standard diet, a cholesterol group receiving 500 mg of cholesterol/100 g of feed per rabbit per 24 h (CH group), and a cholesterol + fluorine
