Abstract

The present study was carried out to study the effect of acute doses of sodium fluoride on the collagen content of the rat kidneys. Five groups of rats were studied: (i) control rats and (ii) rats divided into four subgroups according to the dose of NaF. Results showed that higher doses of sodium fluoride 10, 20 and 30 mg of NaF/kg body weight caused a significant decrease in the collagen content of the kidneys when compared to the control rats. Electron microscope studies supported these results and showed the sodium fluoride doses 10, 20 and 30 mg of NaF/kg body weight caused disruption of ordered collagen fibrils of the rat kidneys.

    BACKGROUND/AIM: Chronic renal disorder is becoming a major health problem worldwide. The purpose of the present study was to investigate alterations in the renal antioxidant system in rats induced by repeated exposure to chlorpyrifos (CPF) alone and in conjunction with fluoride. MATERIALS AND METHODS: Wistar rats were randomly allocated to seven

  • Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence

    A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.

  • Kidney: A potential target for fluoride toxicity

    The kidneys are the organ responsible for clearing fluoride from the body. In the process of doing so, the kidneys are exposed to concentrations of fluoride that exceed, by a factor of 50, the concentration of fluoride in human blood. As such, the kidney have long been considered a potential
