| In order to compare the effects of addition of fluorine (F) in diets differing in protein content on the urinary F excretion, blood profile and thyroid hormones, 30 crossbred calves (6-8 months) initially exposed to different protein levels were allotted into six groups in a 3 × 2 factorial design. The factors included three different levels of protein: normal (NP; 100%), low (LP; 75%), and high (HP; 125%) besides two levels of supplemental fluorine (as sodium fluoride) at 0 or 200 mg/kg diet. The animals were fed a wheat straw-based diet for 210 d. Feeding NP diets decreased urinary fluoride excretion, measured at 42 d intervals, compared with LP diets. Blood levels of hemoglobin and haematocrit, measured at 70 d intervals, were not affected by either... |

| The aim of the present study was to evaluate the effects of sodium fluoride (NaF) on the male reproductive system. Adult male rats were exposed to NaF in drinking water for 30 days at three concentrations: 1.54 (control, tap water), 50 and 100 ppm. Body and organ weights, daily sperm production, sperm number and morphology were investigated. No difference was observed on the sperm number and morphology among the groups, as well as body weight and organ absolute and relative weights. Overall, despite the presence of a mild degree of dental fluorosis in the higher dose group, the results indicated that exposure to NaF at the doses used in the present study did not adversely affect sperm production and morphology of male rats. |
