Abstract
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.

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

Influence of NaF and Na2PO3F(MFP) on glucose metabolism in rat hepatocytes.
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

Physical exercise ameliorates the toxic effect of fluoride on the insulin-glucose system.
Daily intake of water with fluoride concentrations >1.5 mg/l produces insulin resistance (IR). On the other hand, physical activity increases insulin sensitivity in the muscle. Therefore, the aim of this study was to evaluate the effect of physical activity on IR in rats treated with sodium fluoride (NaF) in drinking

Effect of F on rat serum insulin levels in vivo
Several investigators have shown an acute administration of NaF in rats can induce a hyperglycemia. The current study was undertaken to determine if acute injections of NaF would alter the serum insulin levels since LIN et al., Horm. Metab. Res 8, 353-358, 1976 had shown that NaF could inhibit the
