Abstract

Fluoride toxicity through potable water, particularly ground water, is not uncommon in countries such as India, China, Iran, Iraq, Turkey, parts of Africa and Afghanistan. Kidney being the main organ involved in fluoride removal, it accumulates considerable amount of fluoride. Here, we report toxic effects of oral exposure of Swiss albino mice to fluoride (sub-acute: 190 mg/kg body wt. for 7 days; and sub-chronic: 94 mg/kg body wt. for 90 days) and recovery of sub-chronic fluoride exposed mice after 90 days of sodium fluoride (NaF) withdrawal. The role of diet supplements (Spirulina and tamarind fruit pulp @ 230 mg/kg body wt. independently as well as in combination) in amelioration of fluoride toxicity has also been screened. Compared with controls, feed intake decreased from 3-43%, body wt. 4-18%, and kidney wt. 5-12% in treated mice (except diet supplement groups of sub-chronic exposure) while their water intake increased from 4-43%. Histopathological changes in the cortical region of kidney in fluoride treated mice were as follows: dilation of bowman's capsule and thickening of its parietal and visceral layer; alterations in glomeruli size and their sclerotization; increase in bowman's space; proliferation of mesangial cells; reduction in podocyte counts; and dilation of proximal and distal tubules. Fluoride exposure altered tissue biochemistry (protein, acid phosphatase and alkaline phosphatase content) and increased urea (23-58%) and creatinine content (14-127%) in the serum. Sub-acute exposure was found more toxic. The diet modulation not only reduced fluoride toxicity but also led to better recovery of treated mice after withdrawal, especially in combination.
