| Abstract | ||
| This present study carried out in the animal house/laboratory which belong to Biology department in College of education girls/Kufa university ,the present study included assessment changes occurs from two doses of sodium fluoride injected in Newimshair hens bodies for (30)days to estimate the effect of sodium fluoride in tissues of female reproductive system ,The present study revealed: 1-Signifhcant increase (p<0.05)in diameters of primary and secondary follicles while significant decrease(p<0.05)in diameters of mature follicles at dose of sodium fluoride (15)milligram/kilogram. 2-Significant increase (p<0.05)in mean diameters of graffian follicales at doses (10,15)milligram/kilogram of body weight,which estimated(139.5±5.2,125±1.46)micrometer at respectively when compared with control group. 3-The treatment with sodium fluoride lead to significant increase (p<0.05)in the villi of oviduct diameters at dose(10,15)milligram/kilogram of body weight. significant decrease occurred (p<0.05)in the musculature thickness of the oviduct at dose(15)milligram/kilogram of body weight ,which estimated (241±3.11)micrometer when compared with control group and first treatment (424±5.36)micrometer. 4-According to histological changes,the treated with sodium fluoride especially in second dose (15)mg/kg b.w caused alteration in the shape of mature ovarian follicales,and oocyte distortion with hyperplasia in theca externa elements. Also the treatment with sodium fluoride caused sloughing in epithelial cells that lined magnum villi ,as well as hyperplasia occurred in the columnar epithelial cells and connective tissue elements of the villus core. | ||
