Abstract

Adult Swiss Albino mice (6-7 weeks old) were treated with sodium fluoride (NaF) until autopsy. The organo-somatic index, histology and biochemistry of the intestines were observed at commencement of treatment and on the 7th, 15th and 30th day. The crypt cells exhibited cytoplasmic degranulation and vacuolation. Hydropic degeneration in lamina propria and muscular tissue, increase in the number of goblet cells, broken tips of villi, nuclear pyknosis, and abnormal mitoses were observed. The organo-somatic index decreased significantly on days 7 and 15. Total protein and cholesterol values declined significantly, whereas those of glycogen and acid, and alkaline phosphatase activities, increased significantly on day 7 to day 30. The results provide evidence of intestinal involvement in fluorosis.

  • Suppressive effects of dietary high fluorine on the intestinal development in broilers

    Fluoride (F) is a well-recognized hazardous substance. Ingested F initially acts locally on the intestines. The small intestine plays a critical role in the digestion, absorption, and defense. In this study, therefore, we investigated the effects of fluorine on the intestinal development by light microscopy, transmission electron microscopy, and histochemistry.

Colonic microbial structure and diversity was significantly altered by fluoride exposure and probiotic treatment. Fluoride- and probiotic-altered sensitive and well-connected species may be closely related to renal health. Fluoride (F) exposure

    Gastrointestinal symptoms are the first signs of fluoride (F) toxicity. In the present study, the jejunum of rats chronically exposed to F was evaluated by proteomics, as well as by morphological analysis. Wistar rats received water containing 0, 10 or 50 mgF/L during 30 days. HuC/D, neuronal Nitric Oxide (nNOS),

Therefore, the loss of energy may have not been repaired. Morphological changes in the gut, can be explained
