Abstract:
اجريت هذه الدراسة، للتعرف على تاثير خلات اليورانيل والمستخلص المائي لورد لسان الثور Borago officinalis (Borage) معا وكلا على انفراد في ما ياتي : - 1 التركيب النسجي للغدة الدرقية. - 2 مستوى هرمون T3و T4وTSH. - 3 معايير الدم (التعداد الكلي لخلايا الدم ال | The aim of this study was to determined the effects of uranyl acetate and aqueous extract of Borago officinalis(Borage) alone or when they are given toghther the following : 1 - The histological structures of the thyroid gland.2 - Serum concentration T4, T3, TSH Hormones.3 - The blood parameters (WBC, PCV, Hb, Platelet and ESR). A total 30 mature males(Albino Rabbit) were used in this study, and their weights were recorded before and after the experiment. Animals were divided into five groups and administrated by using oro - gastric tube and included these following groups : 1 - (G1) which was given drinking water and considered as control group. 2 - (G2) group treated with uranyl acetate which was given orally only (50mg/kg body weight) for one month.3 - Group G3 which was treated with uranyl acetate with the same concentration used in (G2), then just after one hour they were post - administrated of with aqueous extract of Borage (adose of 5 ml concentration 10%).4 - (G4) group of animals treated with aqueous extract of Borage and adose of 5 ml concentration 10%.5 - (G5)which was pre - treated with uranyl acetate with concentration similar to the dose in (G2) for after one month, then post - administrated of with aqueous extract of Borage at a dose 5 ml concentration of 10%.At the end of the experiments (one month) blood sample was drawn by heart puncture and then ansethized by using ether, animal were killed and thyroid gland prepare for histological study. The following results were recorded : 1 - A significant decrement (p<0.05) in the mean of animals weight (G2, G3, G5) while there are no significant differences in the (G4)as compared with G1.2 - A significant increment (p<0.05) in the mean of (Hb, PCV) of group G2 where as group G3 showed no significant difference.While group G4 and G5 showed decreased as compared with G1.3 - A significant increment (p<0.05) in the mean of WBC in (G2, G3 and G5) while G4 showed no significant difference as compared G1.4 - A significant increment (p<0, 05) in the (G2, G4 and G5) while G3 there are no significant difference as compared G1.5 - A significant increment (p<0.05) in the mean of platelet in (G2, G3and G4) while there are no significant differences as compared with G1.6 - A significant increment (p<0.05)T4 hormone level, in the (G2, G4) while G5 showed a significant decreased where as G3 showed no significant difference as compared with G1.7 - A significant decrement (p<0.05) in the T3 hormone level in the (G2, G4 and G5) while there are no significant differences in the G3 in comparison with G1.8 - A significant decrement (p<0.05)in TSH hormone level in the G2 while no significant changes in the (G3, G4) and a significant increment in the G5 in comparison with G1. Histological results of thyroid gland 1 - A degenerative changes were observed in the epithelial tissues of thyroid gland in the (G2) due to direct effect of uranyl acetate and loss of cell style aggregation in addition to infiltration with inflammatory cells, with loss of depletion of colloid from thyroid follicles.2 - G3 showed normal thyroid cells and thyroid follicles filled with colloid fluid as compared with control group.3 - The result of histology examination of thyroid of group have shown presence of some follicles that contain colloid while ether lack theis colloid.4 - Characterized thyroid follicles cells (G5) lining simple cuboidal tissue but it contains more than one row of cells, suggesting a hyperplasia, but these effects are less negative compared with (G2).From this study we can concluded that uranyl acetate have negative effect on thyroid cells and the chemical substance of aqueous extract of Borago offcinalis inhibit the negative impact of uranyl acetate on thyroid cells in awide aspects of this study, and the aqueous extract of Borago offcinalis have high effect in regulation of thyroid function
