Abstract: ان تشخيص الخمج ضمن فئة حديثي الولادة يعتبر بحد ذاته تحد , نظرا لكون الاختبارات التقليدية غالبا ما تؤدي الى التضليل بدل التشخيص . صممت هذه الدراسة لاجل البت بامكانية استخدام اختبار مستوى البروكالسيتونين كمعلم للتشخيص المبكر للحالات المشكوك باصابتها بتسمم الدم الجرثومي في حديثي الولادة بالمقارنه مع زرع الدم, C - reactive protein , عدم خلايا الدم البيض الكلي والتفريقي. تم جمع العينات التي اشتملت على كلا الجنسين خلال الفترة الزمنيه من شهر اب سنة 2008 ولغاية شهر اذار سنة 2009 من حديثي الولادة الوافدين الى ردهات الخدج والاطفال في مستشفى تكريت التعليمي والمشخصه سريرا من قبل طبيب الاطفال المختص على اشتباه اصابتهم بالمرض. لقد اشتملت الدراسه على 114 حاله اجري فحص زرع الدم في جميعها بينما اجريت فحوصات الدم ل 102 حاله , تم فحص CRP ل 84 حالة واختبر مستوى البروكالسيتونين في 73 حالة حيث يعزى عدم تساوي العدد الى عدم كفاية الدم لاجراء جميع الاختبارات . اظهرت نتائج زرع الدم ان 53 (46%) من العينات كانت موجبه منها, 32 (60%) ذكور و21 (40%) اناث . عدد حالات زرع الدم السالبة كانت 61 ( 54%) منها , 31 (51%) اناث و30 (49%) ذكور.اظهرت نتيجة التشخيص المختبري بان العزلات البكتيرية الاكثر شيوعيا كانت من جنس البكتريا العنقوديه السالبة لانزيم التجلط ومن Nocardia spp. لانزيم التخثر بنسبة 22% لكليهما تتبعها بكتريا Listeria monocytogenes بنسبة 17% تليها Klebsiella pneumoniae بنسبة 9% و6 % لكل منPseudomonas aeruginosa وStaphylococcus aureus اما باقي الانواع (Citrobacter diversus, Serratia marscesens, Serratia liquifascens, Lactobacillus spp., Peptostreptococcus spp., Micrococcus spp., Streptococcus pyogenes ) فقد كانت غير شائعة واعطت نسب 2% لكل واحد . بينت هذه الدراسة ان حملة تسمم الدم الجرثومي المتاخر سجلت 67% من الحالات بينما الباقي من النسبه ( 33%) كان ل حملة تسمم الدم الجرثومي المبكر .لقد كان عدد حالات التسمم الجرثومي المؤكد بين الذكور اعلى 32 (60 ) منه في الاناث 21 (40%). تبين ان من بين جميع المظاهر السريريه , قلة الرضاعة شكل اعلى نسبة بينما اعراض تبقع الجلد والقباع اعطت اقل نسبة, كما وبينت بان 30% فقط من الاصابات كانت عند الاطفال ذوي الوزن الطبيعي بينما شكل الاطفال الذين يقل وزنهم عن الطبيعي نسبة 70% . اظهرت دراسة عوامل الخطورة في الامهات بان العامل الاكثر شيوعا كان تمزق الغشاء الامنيوني لفترة تزيد عن 18 ساعة يتبعه عامل التهاب المجاري البولية والحمى واختناق داخل الرحم بالتتابع. نسبة الوفيات كانت اعلى في الحمله المتاخره لتسمم الدم كما كانت نسبة الوفيات اعلى عند حديثي الولادة ناقصي الوزن عنه عند ذوي الوزن الطبيعي احصائيا, كان لذوي الوزن الاقل من الطبيعي اهميه من الناحيه الاحصائيه . اظهر اختبار فحص الحساسية ان عزلات البكتريا السالبة لصبغة كرام كانت ذات مقاومه عاليه للمضادات المستخدمة في الدراسة الحالية بينما كل عزلة من عزلات البكتريا الموجبة لصبغة كرام كان لها نمط مقاومه مختلف للمضادات . كما واظهرت الدراسة لعوامل الضراوة بان العزلات البكترية السالبة لصبغة كرام كانت موجبة لاختبار انتاج انزيم اليوريز واختبار انزيم الهيمولايسن واختبار انزيم اللايبيز واللسيثينيز والبروتييزبنسبة 85% , 100% , 100% , 100% و62% على التوالي بينما كانت العزلات الموجبة لصبغة كرام موجبة للاختبارات بنسبة 61% , 100%, 89%, 94% و785 عالتوالي. اظهرت فحوصات الدم الروتينيه والتي كانت ذات قيمه معنويه بان 33% من بين حالات زرع الدم الموجبة كان عدد خلايا الدم البيض فيها منخفض , 19% من الحالات كان عدد الخلايا البيض مرتفع اما باقي النسبة المؤية فقد كان نتيجة فحص عد خلايا ضمن المستوى الطبيعي فيما يتعلق بحالة تواجد الخلايا العدله غير الناضجة في الدم المحيطي فقد بينت الدراسه ان 79% من حالات زرع الدم الموجبة كانت ايضا موجبة من ناحية تواجد الخلايا العدله غير الناضجه فالدم بينما باقي النسبة ضمن حالات زرع الدم الموجب فقد كانت سالبة لتواجد هذا النوع من الخلايا.علما ان الاختلافات الاحصائيه المتعلقه بالخلايا العدله غير الناضجه كانت ذات قيمة معنويه عاليه. بالنسبة لفحص CRP كانت الفروقات الاحصائيه غير ذات قيمه معنويه مابين الحالات الموجبه لزرع الدم عن الحالات السالبه . وفيما يخص نتيجة فحص PCT الذي تم قياسه باستخدام طريقة القياس شبة الكمي الكرماتوغرافيه المناعيه فقط ظهر ان تركيز البروكالسيتونين في المصل لم يكن ذا فرق احصائي معنوي بين المرضى المصابين ببكتريا موجبه لصبغة كرام عن المصابين ببكتريا سالبة لصبغة كرام. اظهرت نتائج دراستنا ان 21% من حالات زرع الدم الموجبه اعطت مستوى بروكالسيتونين اقل من 0.5 نانوغرام لكل مل وباقي النسبة توزعت بين مستويات البروكالسيتونين الباقيه ≥0.5 ≥2 ≥10. بالنسبة لحالات زرع الدم السالبة فقد اظهرت نتيجة قياس مستوى PCT بان نسبة 49% كان ضمن مستوى البروكالسيتونين<0.5 نانوغرام لكل مل بينما 51% كانت ضمن المستويات ≥0.5 ≥2 ≥ 10 نانوغرام لكل مل بمعنى لايمكن استبعاد حصول اصابة جهازيه حتى لو كانت نتيجة الزرع الدم سلبية. كما لم تتوافق نتيجة البروكالسيتونين مع نتيجة فحص الCRP لكل الحالات فقد سجلت اعلى مستويات للبروكالسيتونين بينما كان فحص ال CRP لها سالب , ومن مقارنة نتائج عد الخلايا البيض مع نتيجة البروكالسيتونين التي اجريت لنفس الحالات ظهر بان 68 % من الحالات كانت ضمن معدل عدد الخلايا الطبيعي بالوقت الذي اعطت مستوى عالي للبروكالسيتنوين≤10 نانوغرام لكل مل و18% فقط من الحالات كان عدد الخلايا البيض مرتفع وباقي النسبة اشتملت عل حالات انخفض بها عدد الخلايا البيض عن الطبيعي . من بين كل الحالات الي اجري لها فحص مستوى البروكالسيتونين سجلت 39 حالة بنسبة 53 % ظهرت بها الخلايا البيض العدلة غير الناضجة فالدم المحيطي . عند مقارنة اختبار البروكالسيتونين مع باقي الفحوصات الروتينه المستخدمه بالدراسه اتضح بانه اكثر حساسية في تشخيص تسمم الدم الجرثومي وفقا لذلك , نستنتج بان البروكالسيتونين هو محدد اكثر حساسية من الفحوصات التقليدية( فحص زرع الدم وفحص ال CRP وفحص عد الخلايا البيض) في التشخيص المبكر لتجرثم الدم الناجم عن البكتريا عند الاطفال حديثي الولاده . | The diagnosis of neonatal infection is challenging because traditional markers of infection are often misleading instead of diagnosing. This study was conducted to determine Procalcitonin (PCT) level as an early marker for diagnosis of suspected sepsis in neonates in comparison with C - reactive protein, blood culture, total and differential white blood cell counts. From August, 2008 till March, 2009, samples were taken from neonates (males and females) admitted to the pediatrics - neonatal wards at Tikrit Teaching Hospital who were clinically suspected with sepsis as diagnosed by the physician in the hospital with any features suggestive of sepsis. The study includes a total of 114 cases. Blood cultures were done for all cases. Hematological tests were performed for 102 cases. C - reactive protein (CRP) was determined in 84 cases, while Procalcitonin level was determined in 73 cases. The differences in the number of samples involved in each test were due to the inadequate amount of blood specimens to perform all investigations. The results of blood culture showed that 53 (46%) of samples were positive, of them 32 (60%) were males and 21 (40%) were females. The number of negative cases were 61 (54%), of them 31 (51%) were females and 30 (49%)were males. The results of identification showed that the most frequent bacterial isolates were Coagulase Negative Staphylococci and Nocardia spp. (22% for each), followed by Listeria monocytogenes 17%, Klebsiella pneumoniae, 9% Pseudomonas aeruginosa 6% and Staphylococcus aureus 6%, while (Citrobacter diversus, Serratia marscesens, Serratia liquifascens, Lactobacillus spp., Peptostreptococcus spp., Micrococcus spp., Streptococcus pyogenes) were frequently less isolated recording 2% for each . This study revealed that, late - sepsis was recorded in 67% of cases while the rest (33%) were with early - sepsis and also revealed that. The number of proven sepsis were higher in males 32 (60%) than in females 21 (40%). Among all clinical manifestation, poor feeding had the highest proportion, while mottling and grunting had the smallest proportion. Only 30% of neonates were of normal birth weight, while 70% were low birth weight, very low birth weight and, extremely low birth weight respectively. Study of maternal risk factors revealed that the most frequent factor was the Prolonged Rupture of membrane followed by maternally UTI, fever and intrapartum asphyxia, respectively. The fatality rate was higher in late - sepsis cases, also it was higher in low birth weight than in normal birth weight neonates, statistically VLBW had the highest value. The antibiotics susceptibility test revealed that Gram negative isolates showed high resistance to antibiotics used in the present study. Each isolate of the Gram positive bacteria showed different pattern of resistance against the antibiotics used. Results of virulence factor showed that 85%, 100%, 100% , 100% and 62% of Gram negative isolates and 61%, 100% , 89%, 94% and 78% of Gram positive isolated produced Urease , Hemolysin, Lipase, Lecithinase and alkaline protease, respectively. Results of routine hematological tests at which the differences were statistically significant showed that 33% of culture positive cases had leucopenia, 19% of cases had leukocytosis, while the rest were in the category of normal range. Concerning the shift to left, results showed that (79%) of culture positive cases were recorded as positive and the rest were negative shift to left neutrophil the differences concerning with the shift left were statistically highly significant. For CRP, the differences were not significant among culture positive and culture neative cases. With reference to PCT test which had been measured using the immunochromatographic semi - quantitative method, that serum procalcitonin concentrations were not significantly different between the patients with Gram - positive and those with Gram negative infections. Results of our study showed that 21% of culture positive cases were <0.5 ng/ml (which were regarded as negative), while the rest which were with high level of PCT were distributed among levels of PCT≥0.5 ≥2 ≥10 ng/ml. As for culture negative cases, 49% of PCT were <0.5 ng/ml, while 51% of cases were in levels of ≥0.5 ≥2 ≥10 ng/ml which means that systemic infections cannot be excluded though they were culture negative. In addition PCT results did not fit with CRP all the time since some cases recorded higher level of PCT ≥10 ng/ml despite they were negative for CRP. The comparison between results of PCT and WBC for the same performed cases showed that 68% of cases were in the category of normal WBC range, meanwhile they had high level of PCT. Only 18% were in the category of leukocytosis, and the rest of percentage were in the category of leucopenia. Among all cases performed for PCT, 39 (53%) cases had left shift neutrophil in the peripheral blood when the differential counts were performed. when PCT was compared with other routinely measured parameters used in this study, It seemed to be significantly more sensitive in sepsis diagnosis. Accordingly, we can conclude that PCT is a more sensitive marker than other traditional tests (blood culture, CRP and WBC count) that could be used in early diagnosis of bacterial sepsis in neonates.

Abstract: تهدف هذه الدراسة الى اظهار العلاقة ما بين مستويات هرمونات الغدة الدرقية Thyroid hormones (الثايرونين ثلاثي اليود ,T3 الثايروكسين T4) وبين حدوث حالات الحمل المهدد بالاجهاض ، بالاضافة الى تناول دراسة التغيرات الحاصلة في هرموني الاستروجين E2 والبرولاكتين PRL وكذلك الهرمون المحفز للدرقية TSH وعدد من المقاييس الدموية والكيموحيوية (تركيز هيموغلوبين الدم Hb , النسبة المئوية لحجم خلايا الدم المضغوطة PCV% , تركيز البروتين الكلي Total protein ) اثناء الحمل الطبيعي والحمل المهدد بالاجهاض . شملت الدراسة 280 عينة دم تم اخذها من النساء اللاتي تتراوح اعمارهن بين 15 - 36 سنة وممن راجعن مستشفى تكريت التعليمي والعيادات الخارجية لبعض الاطباء, وتم تقسيمها الى ثلاثة مجاميع وهي : الاولى ضمت 160 عينة دم من النساء ذوات الحمل الطبيعي ، والثانية ضمت 80 عينة دم من النساء ذوات الحمل المهدد بالاجهاض والثالثة ضمت 40 عينة دم من النساء غير الحوامل كمجموعة سيطرة . اظهرت نتائج هذه الدراسة ارتفاعا معنويا في تركيز هرمونات الدرقية T3 وT4 في مجموعة النساء ذوات الحمل الطبيعي ( ولجميع اشهر الحمل ) عند مستوى معنوية ( p < 0.01 ) مقارنة مع مجموعة السيطرة ، وكذلك حصول انخفاض معنوي في تركيز هرمونات الدرقية T3 وT4 في مجموعة النساء ذوات الحمل المهدد بالاجهاض (وللاشهر الاربعة الاولى من الحمل ) عند مستوى معنوية ( p < 0.01 ) مقارنة مع مجموعة السيطرة ، بينما لم تسجل النتائج وجود فروق معنوية بين مجموعة النساء ذوات الحمل الطبيعي ( ولجميع اشهر الحمل ) ومجموعة السيطرة في تركيز هرمون TSH,اذ كانت ضمن الحدود الطبيعية , في حين تم تسجيل ارتفاع معنوي في تركيز هرمون TSH في مجموعة النساء ذوات الحمل المهدد بالاجهاض ( للاشهر الاربعة الاولى من الحمل ) عند مستوى معنوية ( p < 0.01 ) مقارنة مع مجموعة السيطرة . اظهرت النتائج ارتفاعا معنويا في تركيز هرمون الاستروجين E2 في مجموعة النساء ذوات الحمل الطبيعي ( ولجميع اشهر الحمل ) مقارنة مع مجموعة السيطرة وعند مستوى معنوية ( p < 0.01 ) وعلى خلاف ذلك اظهر تركيز هرمون الاستروجين E2 انخفاضا معنويا في مجموعة النساء ذوات الحمل المهدد بالاجهاض ( للاشهر الاربعة الاولى من الحمل ) مقارنة مع مجموعة السيطرة وعلى مستوى معنوية ( p < 0.01 ) . وسجلت النتائج ارتفاعا معنويا في تركيز هرمون البرولاكتين PRL في مجموعتي النساء ذوات الحمل الطبيعي والنساء ذوات الحمل المهدد بالاجهاض ( ولجميع اشهر الحمل) عند مستوى معنوية ( p < 0.01 ) مقارنة مع مجموعة السيطرة. ولوحظ ان هناك انخفاضا معنويا في تركيز البروتين الكلي في مجموعتي النساء ذوات الحمل الطبيعي والنساء ذوات الحمل المهدد بالاجهاض ولجميع اشهر الحمل مقارنة مع مجموعة السيطرة وعند مستوى معنوية ( p < 0.01 ) .واخيرا اظهرت النتائج انخفاضا معنويا في قيم بعض مقاييس الدم ( % PCV , Hb ) وفي كلا المجموعتين المدروستين ولجميع اشهر الحمل مقارنة مع مجموعة السيطرة وعند مستوى معنوية ( p < 0.01 ) . وقد اوضحت الدراسة وجود علاقة بين الانخفاض في مستوى بعض هرمونات الدرقية ونسبة معينة من النساء الحوامل المهدد حملهن بالاجهاض مما يعطي تفسيرا بان لهذه الغدة دورا مهما في التاثير على طبيعة الحمل والحفاظ عليه . | This study aims to show the relationship between thyroid gland hormones levels (Triiodothyronine T3, Thyroxine T4 ) and the incidence of threatened abortion pregnancy . the changes in Estrogen , Prolactin and Thyroid stimulating hormone were also investigated. The characteristics included in this work were some blood measurements and biochemical traits ( Hemoglobin Hb , Packed cell volume PCV% and the total protein concentration ) . The work performed through using 280 blood samples taken from women ( 15 - 36 years age ) , attending Tikrit Teaching Hospital and some private medical clinc s. The sample was divided into three groups , the first group represented normal pregnant women ( 160 blood samples ) and the second group included the threatened abortion pregnancy women ( 80 blood samples ) , where as the third group represented a non pregnant women ( 40 blood samples ) which considered as a control group . The results obtained revealed a significant increase ( p < 0.01 ) in the concentration of thyroid hormones ( T3, T4 ) for the normal pregnant women , for all the pregnant months , when compared with the control group . A significant decrease ( p < 0.01 ) was also detected in the abortive threatened pregnancy women , when compared with control group women , regarding T3 and T4 hormones concentration for the first four months of pregnancy . Non significant difference between the normal pregnant women group and the control group. It was evident that TSH concentration increase significantly ( p < 0.01 ) in the threatened abortion pregnant women for the first four pregnancy months when compared with the control group women . Estrogen hormone concentration was found to be significantly ( p < 0.01 ) higher in the normal pregnant women for all pregnancy months as compared with the control group women . On the contrary a significant decrease in estrogen hormone concentral in the abortive threatened women for the first four pregnancy months when compared the control group was found .The prolactin hormone concentration was found to be higher significantly ( p < 0.01 ) in both the normal pregnant women and the abortive threatened pregnant women for all the pregnancy months when compared with the control group . It was revealed that the total protein concentration level for both the normal and the abortive threatened pregnant women decreased significantly ( p < 0.01 ) for all pregnancy months . A significant decrease ( p < 0.01 ) in some blood characteristics ( Hb , PCV % ) for both the normal and abortive threatened pregnant women for all pregnancy months were recorded as compared with the control group . This study confirmed an apparent relationship between the decrease of some thyroid gland hormones concentration and the existence of some percentages of abortive threatened pregnant women , which indicate the importance of thyroid gland effect on the nature and the persistence of pregnancy .

Abstract: ترتبط بعض الامراض النفسية مثل مرض الاكتئاب الشديد والفصام بتغيرات مناعية حتى ولو كان الشخص سليم من الناحية الجسمية. على الرغم من ان هذين المرضين لايعتبران حاليا من الامراض المناعية الاساسية لكن توجد ادلة تقترح كون الالتهاب يلعب دورا في عملية الاصابة بالاك | Psychiatric illnesses, particularly major depressive disorder (MDD) and schizophrenia, are associated with inflammatory processes even in individuals who are otherwise physically healthy. While it is unlikely that MDD and schizophrenia are a primary inflammatory disorder, evidence suggesting that inflammation plays a subtle role in the pathophysiology of MDD and schizophrenia has been obtained. Several studies have shown that proinflammatory markers have increased in these disorders. However, these studies have included patients with obvious inflammation, i.e., patients with C - reactive protein >6 mg/L. A comprehensive study concluding that these conditions are inflammatory disorders and inflammation is due only to these two disorders have not been performed. In the present study, the inflammatory natures of MDD and schizophrenia were investigated. To achieve this goal, serum levels of the interleukins - 6 (IL - 6) and interleukins - 18 (IL - 18), tumor necrosis factor alpha (TNF?), and soluble interleukin - 2 receptor (sIL - 2R) in MDD and schizophrenia were obtained and compared with those of the control group. The total serum and ionized levels of calcium (Ca) and magnesium (Mg) in the studied groups were then measured.Significant increases (p < 0.05) in the serum levels of IL - 6, IL - 18, TNF?, and sIL - 2R in the MDD and schizophrenic groups were observed in comparison with those of the control group. In general, the schizophrenic group showed higher levels of inflammatory markers than the MDD and control groups. These results indicate a clear inflammatory state in both disorders. The schizophrenic patients exhibited significant changes in the ratios of T. Ca/Mg and I. Ca/Mg in comparison with those of the healthy and MDD patients; this finding reveals that T. Ca/Mg and I. Ca/Mg ratios are better indicators of cation state than serum cation levels alone.Basing on the results of the present study, we concluded that the immunological responses of the MDD and schizophrenia are significantly stimulated. These conditions may be considered inflammatory disorders because of increased pro - and inflammatory factors in both disorders.Anti - inflammatory drugs may be potentially used as an adjuvant aid in treating schizophrenia and MDD. Future studies may involve investigating other proinflammatory markers and following up results of treated patients that utilized and did not utilize anti - inflammatory drugs.

The two wavelength of maximum absorption for the two reagents were found (422nm) and (416nm) respectively in ethanol and for the complexes formed between these ions with these reagents were found at (476, 492, 504nm) and (455, 458, 496nm) for cobalt(II) , nickel(II) and copper(II) respectively in aqueous medium.It has been prepared after fixing the optimum condition of concentration and acidity function, through the study of UV - Vis spectrum for reacting of metal solution and two reagents solution. For wide range of pH (5 - 11) and concentration which obey to Beer - Lambert Law.The structures were determine according to the mole ratio method and continuous variation method which is obtained from the spectroscopic studies of the complex solutions. The ratios of (metal : reagent) are equal to (1 : 2) for all the complexes ions.The stability of complexes in the solutions was also studied at the optimum conditions.Diagnosis the solid prepared complexes by UV - Vis spectrum in ethanol solution showed high chromic shift from as compared with free reagents in visible region to all the complexes prepared.Micro elemental analysis for all the complexes were prepared and the percentage of Co(II) and Cu(II) were determined , using flame atomic absorption spectroscopy, it was noticed a great accord between theoretical and particle ratio.The infrared spectrum of chelating complexes also studied and it's compared with the two reagents spectrum. They give notice change with free two reagents spectrum. These showed new bands that were not found original in two reagents spectra but other bands have been changed in shape, in trinity and location. This may indicate that a coordination between the metal ions and the two reagents prepared.The Conductivity measurements for solutions at (1×10 - 3M) in ethanol solution have shown non - ionic character for all chelate complexes.From the above observations, it's suggested stereo shapes for complexes, that show the two reagents (DPIDBSA) and (MBDPI) behave as bidentit reagent, we can conclude that the proposed geometrical structure of all chelate complexes are octahedral.The study also included using spectrum method for determination stability constant of complexes in the thermal rang (25 - 45C?) for complexes with reagent (DPIDBSA) while the thermal rang was (10 - 30 C?) for complexes with reagent (MBDPI), and calculating ?G , ?H and ?S for complexes.The bacterial activity of the ligand and it's complexes were studied toward two type of bacteria : 1 - Pseudomonas. aurginosa 2 - StaphylloCoccus. aureusThe complex of Ni(II) with reagent (DPIDBSA) and the complexes of Co(II), Ni(II) and Cu(II) with reagent (MBDPI) and metal ions solution showed high bacterial activity on Pseudomonas. aurginosa while the solution of two reagents and all chelate complexes prepared also the aqueous solution of metal ions don't showed any activity toward the two type of bacteria (StaphylloCoccus. aureus) (G+ve).

The vaginal examinations were done by gynecologist, two high vaginal swabs were taken from (250) women & a cervical swab from some women with vaginal discharge. General urine examination & blood group with Rh factor were performed for each woman with vaginal discharge. Direct microscopic examination, staining & culture of swabs were performed on different methods for diagnosis of Trichomonas vaginalis, followed to diagnose Candida albicans, Neisseria gonorrhoeae, Chlamydia trachomatis & Treponema pallidum as well as some other bacterial groups. The rate of Trichomonas vaginalis was (2.8%) & Neisseria gonorrhoeae (0.8%), while no Chlamydia trachomatis & Treponema pallidum recorded in this study. The highest rate of Trichomonas vaginalis was among the age group between 15 - 29 years (3.6%), the rate of Trichomonas vaginalis infection was higher among illiterate (5.7%) than educated ones. The highest rate of Trichomonas vaginalis was recorded among those with blood group O & Rh (+ve) (3.8%). The same result was found regarding other microorganisms in both sexes. Statistically the results were not significant.The rate of infections in females was higher than males in all infection except Neisseria gonorrhoeae was recorded highest rate in males(35%). The percentage of mixed infections with Trichomonas vaginalis was Candida albicans (1.6%) & B - hemolytic streptococcus (0.4%). The maximum infections rate in vaginal swabs were Staphylococcus aureus (42.3%) & lowest rate of Neisseria gonorrhoeae (2%). Regarding the distribution of microorganisms isolated from urine samples of females suffering from vaginal discharges, the highest rate of infection was Eschirechia coli (22.2%) & lowest rate of Neisseria gonorrhoeae (2%) respectively. The rate of isolated microorganisms from urethral discharge of males were Neisseria gonorrhoeae (35%) & Escherichia coli (5%). Antibiotics Ciprofloxacin & Amikacin showed good inhibition activity against all pathogenic microorganisms. Regarding the effect of different concentration of metronidazole & medical herbs to the Trichomonas vaginalis invitro, metronidazole showed clear effective inhibition at concentration (1.25%) during 24 hours. The inhibitory effect of Zea mays (both alcoholic & watery extractions) was greater than Apium graveolens & Foeniculum vulgare. At concentration (2.5% & 5%) of Zea mays in both extractions was almost identical to metronidazole.

Abstract: جمعت (140) عينة من المرضى الراقدين لثلاثة ايام فاكثر في مستشفى تكريت التعليمي للمدة من 1 - 8 - 2009 ولغاية 1 - 12 - 2009 بهدف تحديد العزلات الجرثومية الاكثر شيوعا ضمن اخماج مستشفى تكريت التعليمي ومقاومة هذه العزلات للمضادات الحيوية ودراسة العلاقة بين مقاو | One hundred fourti samples were collected from hospitalized patients for three days or more in the Tikrit Teaching Hospital during the period from 1/8/2009 until 1/12/2009 to determine the most commonly isolated bacterial from nosocomial infections in Tikrit Teaching Hospital and their resistance to antibiotics and to study the relationship between antibiotics resistance and plasmid content in the most commonly isolated bacteria and to evaluate the prevalence of these plasmids in the hospital environment. These samples include : (75) Urine, (28) stool, (28) of wound swabs and (9) sputum samples.The incidence of nosocomial infection was (45.7%) of them, urinary tract infections were (50.7%) from (75) samples, followed by wound infections (42.9%) from (28) samples, gastrointestinal infections (39.3%) from (28) samples then pneumonia (33.3%) from (9) samples the nosocomial infections were more common in females and age group 51 - 89 years. Different bacterial species were isolated in this study and the results showed that the most commonly isolated type was Citrobacter koseri in a proporation (21%) of urinary tract infections, followed by the following bacterial species : Escherichia coli (15.7%), Staphylococcus schleiferi (10.5%) , Staphylococcus epidermidis (7, 8%), Proteus vulgaris, Staphylococcus saprophytica, Klebsiella ozaenae, Klebsiella ornithindytica in aproportion (5.2%) for each, Enterobacter aerogenes, Providencia stuartii, Staphylococcus warneri, Staphylococcus aureus, Proteus mirabilis in aproportion (2.6%) for each.Citro. koseri were also the most common in wound infections (25%), followed by the following bacterial species : E.coli (16.6%), P.mirabilis (16.6%), Staph.schleiferi, P.vulgaris, Prov.stuartii and Prov.rettgeri in aproportion (8.3%) for each. Citro.koseri were also the most common in the gastrointestinal tract infections in a proporation (36.3%), followed by E.coli (18.1%), S.flexneri (18.1%), P.mirabilisc, Prov.stuartii, Prov.alcalifaciens in a proporation (9%) for each. . While Strept.pneumoniae was the most common(66.7%) in penemonia cases followed by K.pneumoniae (33.3%).The isolated bacteria were tested for antibiotics susceptibility and it has been found that most of these isolates showed high resistance to the studied antibiotics other than Prov. Stuartti was sensitive to all antibiotics except of Rifampicin and Tetracycline. As well as bacterial species belonging to the genus Staphylococcus were sensitive to Amikacin, Staph.aureus was also sensitive to Nitrofurantoin while Staph.warneri was also sensitive to Ciprofloxacin and Nitrofurantoin also Enterobacter aerogenes was resistant to all antibiotics except for Ciprofloxacin and Nitrofuratoin. Eleven of most commonly isolated bacteria which were multidrug resistant were chosen for the curing experiments using SDS to study the relationship of their plasmids with resistant to antibiotics. The results showed that the cured cells of E.coli lost their resistance to Tetracycline Ciprofloxacin and Cefotaxime which Citro.koseri lost their resistance to Tetracycline while K. ornithinolytica lost resistance to both antibiotics Tetracycline and Ciprofloxacin either P.mirabilis lost resistance only to tetracyclin as well as Strept.pneumoniae lost their resistance to Cefotaxime, tracycline and Ampicillin. Which may mean that the genes responsible for resistance to these antibiotics are located on plasmids as proven by the results of electrophoresis.Electrophoresis results also showed that all studied bacterial isolates had the same plasmid profile which may regarded as an epidemiological pointer that plasmids are conjugative which have the ability to transfer antibiotic resistance to other bacterial strains of the same species or to other different bacterial species.

Four stations were selected for sample collections over the distance of 25 km. Two stations were in Tigris river and two were in the treatment unit. The first selected station was close to the old water purification unit in Tikrit - city. The second station was selected at the treatment unit in AL - Dubaee before the mechanical treatment unit. The third station was selected at the treatment unit after the biological treatment. The fourth station was selected in Tigris river about ten km south of the treatment unit at AL - Dijla town. The study involved an investigation of some physical, chemical and biological aspects of Tigris river and the residence waste discharges to the river. This included air and water temperature, conductivity, PH, dissolved oxygen, BOD, Turbidity, total hardness, calcium and magnesium hardness, chloride, total alkalinity, nutrients (i.e., phosphate, nitrite, silica) , and the concentrations of heavy metals (i.e., cadmium and cupper). The biological factor included the total bacteria counts cultured on nutrient agar. Results of the study clarify the close relation between air and water temperature which varied (8.5 - 36) C0 and (9 - 27) C0 respectively. Conductivity values were relatively high and ranged (128 - 3530) microsemens/cm. River water almost was alkaline during the period of the study. PH values of the first and fourth stations were close in the river, although a value of 6.12 was recovered at station on during May. In all stations, PH values ranged (8.8 - 6.12). River water has a good ventilation, dissolved oxygen values ranges (8 - 11) mg/L at the first and the fourth stations, while these values were (0.1 - 1.34) mg/L at the second and third stations. Mean dissolved oxygen values pointed out the availability of good oxygen concentration for the continuity of living organisms which ranged (0.3 - 5.8) mg/L in Tigris river, while BOD values at the stations second and third were high and ranged (5.6 - 131.2) mg/L. Turbidity was high during April at the stations one and four and ranged (2.03 - 788) NTU in all stations. Total hardness in Tigris river was slightly low - very hardness and ranged (120 - 360) mg/L at the first and fourth stations, while these values were (180 - 480) mg/L at stations two and three.The high total hardness values coincided with the high conductivity values. Concentrations of calcium ions responsible on the calcium hardness ranged (211.4 - 120.7) mg/ L was higher than magnesium ions responsible for magnesium hardness range (5 - 265) mg/L.Records of chloride ions ranged (14.16 - 169.99) mg/L at all stations. However, chloride values at stations first and fourth were among the allowed world values and ranged (14.16 - 42.48) mg/L.Alkalinity values were due to the carbonate and bicarbonate and ranged (35 - 725) mg/L.phosphate values ranged (0.168 - 25.2) µg phosphor atom - phosphate/L. Low nutrient values recorded in Tigris river, while the highest values recorded at second station (treatment unit).Nitrite values fluctuated at all stations and ranged (0.078 - 14.778) µg Nitrogen atom - Nitrite /L. Silica values ranged (648 - 5961.6) µg silicon atom - silica /L. Heavy metals values (Cadmium and Cupper) clarify that, Cadmium were (un sensible), except one value (0.008) mg/L that recorded at November, and un sensible for Cupper.Results of the statistical analyses of all involved factors showed significant differences at stations first and second, and between the first and third stations as well as the fourth station. While there was no significant differences between the second and fourth stations. And no significant differences between stations first and fourth.Total bacterial counts indicated high bacterial counts, and the average of total bacterial count ranged (2.605X105, 5.44X108, 2.265X108, 2.385X105) / ml at the four stations respectively, so the Tigris river considered pollutant - very pollutant.
