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.

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.

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

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,

Intervention of selenium on apoptosis and Fas/FasL expressions in the liver of fluoride-exposed rats
Fluorosis is a major public health problem in numerous areas around the world, including China. To alleviate this problem, selenium has been used. In this study, we aimed to investigate the influence of selenium on apoptosis in fluorosis-affected rat livers and determine the optimal selenium concentration in drinking water to

Studies on the toxicology of fluorine compounds. I. Histological and histochemical investigations on the liver, heart, lungs, and stomach of rats exposed to hydrogen fluoride.
The liver, heart, lungs, and stomach of rats exposed to hydrogen fluoride were studied. Histological examination showed partial liver necrosis and emphysema. Using histochemical methods the effect of fluorine ions was found in: a reduction of the activity of succinic and beta-hydroxybutyric dehydrogenases in the liver, heart muscle, superficial and
