Abstract
Objective: Explore the active mechanisms of growth inhibitors (somatostatin, SS) participating in learning and memory obstacles from brick tea fluoride and aluminum poisoning of rats. Method: Based on the tea-drinking habits of herders, a rat chronic brick tea fluoride and aluminum poisoning animal model was established, and randomly divided into control groups and model groups. After the model was established for one year, an eight-arm maze test was performed to observe the differences in the spatial learning and memory capabilities of the two rat groups, and immunochemistry was used to test the changes in the rat hippocampus growth inhibitor expression one year after the model was established. Results: Compared with the control group, there was a significant difference (P<0.01) in the rat eight-arm maze learning and memory capabilities one year after the model was established, and the rat hippocampus SS expression fell (P<0.01) one year after the model was established. Conclusion: Brick tea fluoride and aluminum poisoning of rats obstructs learning and memory and brain tissue SS expression decreases.

Experimental pharmacological researches regarding the influence of sodium fluoride in allopathic and homeopathic doses in central nervous system's performances. A correlation between behavioral response in classic maze test and morphological aspects of cerebral cortex
The influence of fluorine administration on central nervous system’s (CNS) performances in female mice treated during gestation with two distinct doses of sodium fluoride (NaF): 0.25 mg and 0.50 mg. The research extended also to offspring (generation 1 – F1), treated with NaF in allopathic (0.25 and 0.50 mg), homeopathic

Effects of chronic fluoride exposure on object recognition memory and mRNA expression of SNARE complex in hippocampus of male mice
This study aimed to investigate the effects of long-term fluoride exposure on object recognition memory and mRNA expression of soluble N-ethylmaleimidesensitive fusion protein attachment protein receptors (SNARE) complex (synaptosome-associated protein of 25 kDa (SNAP-25), vesicle-associated membrane protein 2 (VAMP-2), and syntaxin 1A) in the hippocampus of male mice. Sixty sexually matured

Effects of high fluoride and arsenic on brain biochemical indexes and learning-memory in rats
Nine-six Wistar rats were randomly divided into four groups of 24 rats in each group (female:male = 1:1). Over a period up to 90 days, with one untreated group as controls, the other three groups were administered, respectively, high fluoride (100 mg NaF/L), high arsenic (50 mg As2O3/L), or both

Influence of chronic fluorosis on expression of phospho-Elk-1 in rat brains.
Objective: To investigate the expression and distribution of the downstream substrate of extracellular regulated protein kinase(ERK1/2) pathway, ternary complex factor phospho-Elk-1, in rat brains with chronic fluorosis, and reveal the mechanism of the impaired learning and memory ability caused by chronic fluorosis. Methods: Seventy-two SD rats, weighing 100 - 120 g,

Fluoride Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

Fluoride: Developmental Neurotoxicity.
Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching

Fluoride's Direct Effects on Brain: Animal Studies
The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.
