The study aimed to investigate if taurine could help reduce sodium fluoride-induced toxicity in chicks. The chicks in this study were divided into four equal groups, each with eight chicks: the control group, sodium fluoride 20 mg/kg group, taurine 3 g/kg group, the fourth group was dosed with each of the sodium fluoride 20 mg/kg and taurine 3 g/kg groups all groups were dosed orally. The dosing was set at 5 days/week for 4 weeks. After 2 and 4 weeks of treatment, the group treated with taurine alone or with sodium fluoride showed an improvement in neurobehavioral and motor activity, as evidenced by a reduction in the duration of chick immobility in the immobility test and an increase in the number of squares cross in the open field test compared to the group treated with sodium fluoride alone. The level of ALT enzyme and calcium in the group treated with sodium fluoride increased significantly compared to the control and taurine group alone, and with sodium fluoride, AST and creatinine levels increased significantly after 4 weeks of sodium fluoride treatment compared to the other groups. When it came to measuring malondialdehyde and glutathione, the sodium fluoride group alone showed a significant increase in malondialdehyde and significant decrease in glutathione after 2 and 4 weeks of treatment when compared to the control and the other groups. The histopathological examination confirmed the previous findings, with the histological sections of the liver, kidney, and brain showing a significant improvement in the group treated with sodium fluoride and taurine after four weeks of treatment. We conclude from this study that taurine has a clear therapeutic effect against oxidative stress, as evidenced by behavioral and motor behavioral effects, as well as levels of glutathione, malondialdehyde, and liver function enzymes, and serum creatinine, as well as histopathological examination of the brain, kidneys, and liver.

The aim of this study to explore the therapeutic effect of boric acid on the neurobehavioral (motor activity) level, and histopathologic changes in the brain, liver and kidneys against fluorosis. In this study rose chicks have been used and determined medium lethal sodium fluoride dose at 346.5 mg/kg orally. The chicks divided into four random groups each one consists of 10 chicks. The first group considered to be a control group, the second received 20 mg/kg of sodium fluoride, the third group received 10 mg/kg of boric acid and the fourth received 20 mg/kg of sodium fluoride and boric acid at the same previous dosages. After two weeks of daily treatment, neurobehavioral measures were taken, the use of boric acid has a major effect to improve the neurobehavioral measurement and develop complications of ALT, AST, creatinine, Ca, MDA. The results indicate that boric acid may be a therapeutic agent against the fluoride toxicity of the brain, liver and kidney. This result support by histopathological changes which represented by inflammation, congestion of portal vein and dilation of sinusoids in the liver and vacuolation, vasogenic edema and gliosis in the brain and Kidney of showed segmentation of glomeruli, dilation of Bowman’s space, necrosis of epithelial cells renal tubules and hemorrhage of NaF group, while the liver of the NaF with boric acid group showed an improvement the results of histopathological examination of the liver, brain and kidneys compared to the NaF group alone. The results revealed that boric acid has a preventing effects against fluoride after two weeks of treatment with boric acid.

The current study aimed to determine the pathological effects of chronic poisoning with sodium fluoride on some reproductive organs like ovary, and testis of adult’s male and female albino rats. Thirty-six male and female adult’s albino rats were divided into six groups. The first and second group of male and female rats are control groups was given tap drinking water, the third and fourth groups of male and female rats was given 150 ppm of NaF, the fifth and sixth group of male and female rats was given 300 ppm of NaF respectively for 90 days. The weights of male and female genital were recorded. Histological exam of control groups of female rats showed the typical histological structure of the ovary, while the NaF treated groups showed a decrease in growing follicles, in addition to thickening in tunica albuginea and deposition of eosinophilic material. In male control groups, the sections showed the typical histological structures of the testis, while the treated groups showed multinucleated spermatids in addition to the deposition of amorphous eosinophilic material in the interstitial tissue, coagulative necrosis, in addition to apoptotic and sloughed spermatogonia in the lumen of seminiferous tubule. These results indicate that sodium fluoride with 300 ppm has toxic effects on organ body weights and on the histology of the gonads of adult’s male and female albino rats.
