المستخلص: Since long time, man interested in history whether by a scientific knowledge or be a desire to save his remarkable deeds and glorifying forefathers. This is to express his affiliation to his society and living land. Interest in saving history varies according to variety of cultures and their people, for each civilization has its own history. Arabs were the first who interested in saving their religious and cultural heritage. And in spite of the modest historical material of Arab history before the prophet mission that reached us; it is in fact a history that needs a lot of thorough examination and purification particularly in what concern with the religious side for most of its sources came through poetry, legends, folklores, and from some old Testament books. The prophet mission had great influence on development of history science for Arabs because of entrance of Arabic history into new era of documentation dew to the news that came through Holy Quran about previous nations. This is in addition to appearance of prophet Mohammed ( p.b.u.h.)as an Arabic personality that made a change in Arab peninsula and neighboring communities. This directed historians towards Arabic and Islamic history that started since descending of inspiration. This interest did not prevent fabricators to insert their lies to Islamic history particularly the prophet biography exploiting authority's prevention for writing down from one side and for the political conflict from the other side. Thus, the land was fertile and there was enough space to plant many lies in theprophet's( p.b.u.h.)biography. Despite of severity and verification means that muslim scholars in accepting or refusing narration, fabricators exploited transferring and narrating rules and source refusal to insert their subjects. Therefore, the source was a means to pass the faults and detestable narrations. Accordingly, there was a reason for a study deals with the source and narration and their influence on the historical fabrication process. This is what mentioned by Prof. Dr. Ayad Al kheffaji. He chose the prophet's biography to be his study, and in particular the Meccan period of the prophet life for its importance in the Islamic history. In addition, it was a very fertile land for fabricators because most of its events were not documented that makes easy for them to add whatever sources they want to the weak narrations. Our work in the dissertation was to discover whatever relates to the prophet's biography when he was in Mecca, starting from his birthday to his immigration to Medina, then studying sources and bodies narrations. For each narration had its own privacy that differs from others. There was the weak narrations whether by its source or body. Others had no source. Thus, there was necessity to criticize the text by comparing it with other historical tests one time and submitting it to the mind and logic on the doctrine criteria

المستخلص: The Islamic legislation has two main resources : the Holy Quran and the prophet instructions ( Sunneh). These instructions means what is said or done or accepted by the prophet. Thus, the forerunner Muslims or the prophet's companion took much care of what the prophet did. Some were writing down what they were hearing in their meeting with the prophet. So, recording at the beginning was an attempt to collect the aural sayings; it had no title and no subject unity. Therefore, the prophet's companions' recordings were called the companions' writings. Al Hedeith writing was started in Al Medinah Al Munewarah for it was Islamic State center and homeland of the prophet and his companions; that's why these writings took the narrative Hijazi style. It was characterized by taking care with prophet's Hedeith and attaching the biography with it. That's why the prophet's Hedeith moved side by side with the history for a long duration. One can hardly find a saying in biography without the prophet's Hedeith especially during Al Medinah stage. That was simply because of state building and society planning as well as economic management. However, the researcher finds difficulty to separate them when talking about the sayings. If he mentioned the companions' sayings, his pen unintentionally writes about the prophet's Hedeith. It is a necessity one cannot avoid. But recording was stopped during Omar Bin Al Khettab era. The Islamic state formally did not adopt a decision for writing till the era of Umayyad Omar Bin Abdul Aziz ( 99 H. - 101 H. / 717 - 719 A. D. ) when he saw a necessity for recording. From that date , the scholars worked hard for writing, and from that time Al Hedeith and the prophet's biography were separated to be the core modern science, that because it is an independent science with its own bases and origins. Some persons were great with a high level of philology of this science. Among those scholars was Al Beiheki. His book Al Sunen Al Kubrah was comprehensive for all the prophet's Hedeith in addition to a large number of the prophet's companions' narratives in all fields political, social, economic, and creedal. Thus, he decided to tackle the social and economic sides of the companions' narratives through Al Sunen Al Kubrah book. So, the current thesis was entitled (the companions' narratives in Al Sunen Al Beiheki : A study in the Social and Economic States. Our study procedures implemented collected the companions' narratives of the economic and social impressions. It has two sections. The first is devoted in the social narratives; it is in turn, was divided into three sections. The first dealt with marriage and family system, while the second was about social complementarity in Islam, and the third discussed fashion and general cleanliness. Second chapter mentioned the economic companions' narratives, it has two sections. The first was about the financial resources of the Islamic state. It collected narratives relate to the state incomes such as almsgiving fifth, tribute, booty, war profiteer and Faiy'a the second section mentioned the economic activities that the companions' narratives wrote about. This included the agricultural activity, crafts, industries, and commerce activity. It is worthy to mention that the study preface stated Al Beiheki biography.

المستخلص: مر الاقتصاد العراقي بظروف استثنائية في العقود الماضية من حروب دامت لمدة طويلة كانت نتائجها وخيمة على واقع الاقتصاد العراقي من استنزاف للموارد الاقتصادية وكذلك على واقع السياسات الاقتصادية, تلاها حصار اقتصادي شديد استمر لاكثر من عقد من الزمن الذي اثر في تراجع جميع المؤشرات الاقتصادية, وفي ظل هذه الظروف لجات الدولة الى اتباع سياسة الاصدار النقدي الجديد لتمويل الانفاق العام لسد حاجات المواطنين, وهذه السياسات ادت حدوث تضخم جامح وتدهور قيمة العملة المحلية . اما بعد عام 2003 وفي ظل الانفتاح الاقتصادي وتزايد عائدات النفط لم نلحظ حدوث اي تغيير في واقع الاقتصاد العراقي وانما تعميق الطابع الريعي ولم يكن هناك توجهات للسلطات العامة لرسم سياسات اقتصادية تهدف لاعادة بناء الهيكل الاقتصادي وازالة الاختلالات الهيكلية التي يعاني منها وكذلك ابعاد الاقتصاد عن تاثير الصدمات الداخلية والخارجية . تنطلق هذه الدراسة من فرضية مفادها "ان هناك علاقة توازنية طويلة الاجل بين متغيرات الاقتصاد الكلي ومتغيرات السياسات الاقتصادية". ومن اجل اختبار هذه الفرضية فان الدراسة قسمت الى ثلاثة فصول, تناول الاول الاطار النظري لسياسات الاقتصاد الكلي والثاني تناول تحليل المتغيرات الاقتصادية في العراق اما الثالث تناول قياس تحليل دوال الاقتصاد الكلي والسياسات الاقتصادية وتم الحصول على نتائج النماذج القياسية باستعمال انموذج الانحدار الذاتي للابطاء الموزع (ARDL), والذي يعد من الاساليب القياسية المتقدمة, والذي يعتمد على اختبار استقرارية السلاسل الزمنية ويعطي هذا الانموذج نتائج عن طبيعة العلاقة في الاجلين القصير (انموذج تصحيح الخطا) وكذلك نتائج للاجل الطويل. وقد توصلت الدراسة الى مجموعة من الاستنتاجات من اهمها وجود علاقة توازنية طويلة الاجل فضلا عن العلاقة قصيرة الاجل بين متغيرات الاقتصاد الكلي ومتغيرات السياسات الاقتصادية وكذلك كانت سرعة التكييف في اغلب النماذج سريعة نسبيا ومن ثم فان الاختلالات التي يمكن ان تحدث سوف يتم تصحيح النسبة الاكبر منها في السنة نفسها واعادتها تجاه القيمة التوازنية طويلة الاجل. | The Iraqi economy has experienced exceptional circumstances in the past decades of war that lasted for a long time and its results on the reality of the Iraqi economy from the depletion of economic resources as well as the reality of economic policies, followed by a severe economic siege lasted for more than a decade that affected the decline in the values of economic indicators, Under these circumstances, the state resorted to adopting the new monetary policy to finance public expenditure to meet the needs of citizens, and these policies were offset by the gross inflation and deterioration of the value of the local currency. After 2003, with the opening of the economy and the increase in oil revenues, we did not notice any changes in the reality of the Iraqi economy, but rather the deepening of the rentier nature. There were no directions of the public authorities to formulate economic policies aimed at rebuilding the economic structure and removing structural imbalances, Internal and external shocks.This study is based on the hypothesis that there is a long - term balance between macroeconomic variables and economic policy variables.In order to achieve this hypothesis, the study was divided into three chapters, The first dealt with the conceptual framework of macroeconomic policies and the second dealt with the analysis of economic variables in Iraq. The third dealt with the modeling of macroeconomic functions and economic policies. The results of the standard models were presented using the ARDL model, Which is one of the advanced standard methods, which depends on the test of stability of time series This model gives results on the nature of the relationship in the short term (error correction model) as well as long - term results. he study reached a number of conclusions, the most important of which is the existence of a long - term equilibrium relationship as well as the short - term relationship between macroeconomic variables and economic policy variables, and the speed of adjustment in most models was relatively rapid. Therefore, the imbalances that can occur will be corrected. Same year and return it to long - term equilibrium value.

المستخلص: The rate of cancer infection has increased with a clear rise in the incidence of leukemia in Iraq's common diseases in 2017, which was the seventh place in 1989, as follows. Generally, about 10 among 100,000 people are infected with leukemia, male have the biggest ratio between the patients with leukemia, finally, Acute Lymphocytic Leukemia is increased at patients with 3 to 7 years old. During the period from the beginning of February 2016 to the first week of 2017 in the Center of Oncology of Hematology in the medical city of Hussein in Karbala', 30 patients with acute lymphocytic leukemia their age were ranged from 2 - 13 years old (19 male and 11 female), without familiar history with cancerous disease. The samples were collected before treatment with chemotherapy, and they were follow - up during the stages of treatment. The control group included 30 samples ranging from 1 - 13 years (18 males and 12 females) Numerous biochemical and histological parameters were assessed in the samples of study patients before and after receiving treatment and the recorded results were compared to the control group. The results of the study showed significant results (p<0.05) at the levels of CLEC4E, MDA, Ceruloplasmin Oxidase Concentration and EOP in the group of animals with acute lymphocytic leukemia before receiving treatment compared to healthy individuals. The current study showed decreased concentrations of CLEC4E, Ceruloplasmin Oxidase Concentration, Ceruloplasmin Oxidase Concentration and Ceruloplasmin Oxidase Activity, while EOP levels increased after chemotherapy, while MDA remained at an unrecognized level at diagnosis. The study showed significant differences (p=0.000) when elevating a number of blood parameters, WBC level and Ferritin concentration. When the stud recorded statistically significant rise in the level of platelets and Hb concentration before chemotherapy. At diagnosis, the present study showed a significant difference (p<0.05) in Fe, Cu, Zn and Ni levels in the patients group, before treatment. However, statistical analysis of trace elements in the sera of patients after treatment didn’t show significant differ than their levels at diagnosis. The study the effect of acute lymphocytic leukemia in the function of kidney showed significant increase in the levels of ANP and Urea in sera of patient samples as well as levels of urinary microalbumin comparison to control group levels, contrast to that, Creatinin levels showed significant (p=0.001) decrease in serum of patients group. Comparative study showed that there were statistically significant differences (p=0.000) of ANP, Urea, Creatinin, Uric Acid, and Microalbumin in patients with acute lymphocytic leukemia after receiving chemotherapy compared to healthy peers.In order to evaluate liver function, GOT and GPT levels as well as STP levels in patients with leukemia were observed within the range recorded in healthy individuals. On the other hand, the current study showed a rise in the levels of ALP enzyme in patients exceeded twice that recorded in the group of healthy children. After receiving chemotherapy, the study showed a significant increase (p=0.000) for GOT, GPT and ALP levels for the group of patients compared to healthy individuals, a significant decrease (p=0.000) of STP levels in the group of patients compared to healthy patients. The study identified many differences between patients and healthy males as well as between infected and healthy females at the level of implicit comparisons between the two groups at diagnosis and after treatment, as shown in the table below which summarizes the relationship between patients of both ganders with their healthy peers. The current study showed statistically significant statistically associations, the clearest among them was recorded when CLEC4E correlated to EOP, which were positive in 100% of the study samples at diagnosis and negative in the same samples after receiving chemotherapy. The results of the study showed that 80% of children with acute lymphocytic leukemia were with type 1, L1, 17% of type 2, L2 and 3% of the third type L3, the promise of the first type has a good outcome of the disease as the response is good for treatment and go through recovery after treatment.

المستخلص: Dexamethasone (DX) is considered one of the steroidal drugs which have varieties of clinical application in medicine for treatment of many different cases. The present study was aimed to know the effect of DX on the implantation of blastocyst during the days 7 and ten of pregnancy, and the process of development of cartilage and bones in the fetuses of albino rats during the days 15 and 20 of pregnancy. In addition to that some physiological parameters aimed to be elucidated in the pregnant rats. The study was conducted in the department of Biology \College of Education for Pure Sciences/ University of Karbala in the period of April, 2016 to May 2017. Ninety four albino rats have been used, among them 10 male rats were used for matting with 84 female rats .The females were divided into three groups, with 28 rats for each group . The first control group was injected with physiological normal saline (0.9%) intraperitoneally. The other two groups were received daily injection via the same route with 0.2 and 0.4 of DX \ 250 gm. of body weight respectively. Each group was further subdivided into four subgroups with seven pregnant female rats for each one. The pregnant rats of each subgroup were sacrificed on the following days : 7,10,15, and 20 respectively The subgroups of the latter two days were used to study the development of the cartilage and bones. Half of the embryos on day 20 of pregnancy from the control and treated groups were used for histological sectioning; while the other half were used to stain the embryonic skeleton according to double staining technique of Whitaker and Dix . All the collected samples which include the implantation sites from the pregnant uteri at days 7 and 10, together with whole embryos from days 15 and 20 of pregnancy, were put in two types of fixatives : 10% formalin and Boun's solution. The collected samples then processed according to the traditional methods of paraffin embedding to be cut into sections of five µm thicknesses. The sections were stained by haemotoxylin and eosin (H&E); one step trichrome; periodic acid Schiff's (PAS) with and without diastase; Alcian blue at pH 1.0 and 2.5. Blood samples from pregnant rats were collected on days 7,10,15,and 20 of pregnancy to check for the following biochemical parameters : concentration of calcium ,phosphate and potassium ions ;alkaline phosphatase ,and acid phosphatase enzymes; and estimation of parathyroid and calcitonin hormones. The results of the H&E stained section of pregnant sites of both the control and treated groups have shown that blastocyst was implanted in the antimesometrial side of the uterus. Most of this side of the uterus has become decidualized tissue, where four zones could be identified : the primary decidual zone; secondary decidual zone ;implantation site; and undifferentiated decidual basal zone. On day 10 of pregnancy the embryos have shifted their position from the antimesometrial side to the mesometrial side of the uterus. The decidual tissue has grown wider and included most of stromal cells of the endometrium. The changing of the position of the embryos at day 10 is important for their survival because they will become nearer to the main blood supply to uterus which are running in the mesometrium. The results of the one step trichrome stained sections from both the control and treated groups have shown clear distribution of collagen fibers in the decidual tissues at days 7 and 10 of pregnancy, which gave an indication of the success of pregnancy up to these stages. The primary decidual zone was devoid of collagen fibers but they are evident in the secondary decidual zone. At day 10 of pregnancy the collagen fibers were more in evidence especially at the mesometrial side of the uterus. The importance of collagen fibers was to give support to the blood vessels supplying the placenta which are coursing through the mesometrium. Positive stain has been revealed in PAS reaction in decidual tissue on day seven of pregnancy without diastase, but it was negative with diastase. No reaction ,in the decidual tissue, with and without diastase was noticed at day ten of pregnancy. With Alcian blue pH 1.0 no reaction was noticed in the decidual tissue of both control and treated groups at days seven and ten of pregnancy. On the other hand positive reaction has come out at pH 2.5. The reaction at that pH was more prominent at the antimesometrial decidual tissue. But it was only depicted in the wall of blood sinusoid of the mesometrial decidual tissue. Tongue like extensions of trophoblasts was noticed to be extending from the recently implanted embryo toward the endometrium, at day seven of pregnancy of both the control and treated group. The trophoblasts were pushing themselves in the direction of mesometrial decidual tissue in order to reach and settle nearer and in the wall of the blood sinusoids of that area. The invasion trophoblasts destination was to reach to the spiral arteries supplying the labyrinthine placenta in the rats. At the 15th day of gestation there was no significant change in the cartilage model in the posterior limbs of the two treatment groups from the control group. The important signal indicated by the present study was observation of cartilaginous cell necrosis, hyperplasia and inflammatory cell infiltration, At the age of near the end of pregnancy in the treatment groups, many of the effects on the bone tissue, which are the existence of a vacuum around the bone cells and the infiltration of inflammatory cells in addition to bone erosion and arthritis and the reduction of cartilage and irregularity of medicine Surface area, hyperlipidemias and leavicular necrosis. Bone marrow squeaks in the control group and the first dose group of dexamethasone were found to be more extensive than the second treatment group. The bones of control group embryos stained with alizarin red has acquired much more red coloration than the treated group embryos, which indicated a slowdown of ossification in their bones compared with control group, Showed that the length of the skull, spine, forelimbs and hind limbs of the fetal fetus at the age of 20 days of gestation of from the treatment groups has decreased for length in the control group but the decline was not significantly level (P <0.05) . The calcium, phosphate and potassium ions concentration was low in the blood serum of treated group ( P< 0.05) during the whole period studied. However the phosphate ions was low in the control group .For the alkaline phosphatase level, it was significantly low ( P< 0.05) in the treated groups compare with the control. On the other hand the level of the acid phosphatase was high in the treated group ( P< 0.05). The concentration of both the parathyroid and calcitonin hormones was significantly higher ( P< 0.05) in the treated groups compared with control. In conclusion, the present study has revealed that DX treatment showed no interference with the process of implantation during the days seven and ten, and with chondrogenesis on day fifteen of pregnancy. While the effect on cartilage formation on the fifteenth day and bone on the twentieth day of pregnancy.
