Abstract: تم دراسة الظروف الطبيعية الموجودة في القاعات الانتاجية لمصنع ادوية سامراء من خلال العوامل البيئية التي شملت الحرارة، والرطوبة النسبية. وشدة الاضاءة واعداد حجم الدقائق العالقة في الهواء وتاثيرها على الاحياء المجهرية الموجودة في القاعات الانتاجية حيث تم اخذ | The natural environmental conditions existing in the production units of Sammara drug company have been studied. Environmental factors included, temperature, relative humidity, light intensity as well as number and size of suspended particles in the air. From December 2006 through June 2007. 87 sampling visit was made during which 384 swabs were collected from three production buildings : Ibn - Hayan, Ibn - Sina and Al - Zahrawy. Results showed that at different temperature levels during this study dominance of bacterial colony over fungal colony in two buildings Ibn - Hayan and Ibn - Sina, was observed, whereas the dominance of fungal colony over bacterial colony in Al - Zahrawy building was noticed. While the effect of relative humidity on microorganisms showed that in Ibn - Hayan building at low relative humidity (41 - 53%) the dominance of bacterial colony over fungal colony whereas the dominance of fungal colony on bacterial colony at relative humidity (53 - 62%). While in Ibn - Sina building bacterial colony dominante fungal colony except at high relative humidity (63 - 73%), where the fungal colony dominance. The same pattern have shown in Al - Zahrawy building at low relative humidity less than 51% while fungal colony exceeded bacterial colony at high relative Humidity. Result of the effect of light intensity showed that the low light intensity have greater effect on fungal colony than bacterial colony this clear in Ibn - Hayan and Ibn - Sina buildings whereas increases in light intensity showed the reverse while the low light intensity in Al - Zahrawy building shown different effects which the dominance of fungal colony over bacterial colony. This perhaps reflects the different species of fungal colony in production units.The effect of the number and the size of 0.3 micron of particulates on bacterial and fungal colony was also examined. It has been noticed that the dominance of bacterial colony over fungal colony until the number of particulates 49000/foot3 in Ibn - Hayan building, while fungal colony appeared in most swabs in Ibn - sina building, but dominancy for bacterial colony. While in Al - Zahrawy building the swabs showed clear appearance for fungal colony, but some swabs shown high bacterial growth. The effect of 0.5 micron particulates showed that the dominance of bacterial colony with increased number of particulates in Ibn - Hayan building. The same pattern was shown in Ibn - Sina building, while in Al - Zahrawy building it has been the dominances of bacterial colony until 15000/foot3, but with increase in number fungal colony appear very clear. The following bacteria and fungi were identified during the course of this study; Staphylococcus, E.coli and a low genera of fungi like Penicillium, Aspergillus, Mucor. It has been shown by the collected swabs that the contamination with bacteria and fungi of drug production units never exceeded the standard limits set by the company except in very rare occasions the high contamination rate occurred in the hands of workers and delivery boxes in Ibn - Sina building.

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
