Abstract: Asthma is a chronic inflammatory disease of the airways in which many cells and cellular elements play a role. Causes recurrent episodes of wheezing, breathlessness, chest tightness, and coughing. These episodes cause airflow obstruction, often reversible either spontaneously or with treatment. The current study was conducted at the Labs of college of Education for pure science and Al - Hussein Teaching Hospital in Thi - Qar province, during the period from October 2014 to May 2015. The study aimed to investigate role of polymorphism of IL - 13 gene in patients with asthma and to evaluate their immune status by measuring the levels of some immunological parameter immunoglobulins ( IgE) by enzyme - linked immunosorbent assay (ELISA) and (IgG, IgM ) by single redial immune diffusion (SRID) and measure the levels of interleukins (IL - 6, IL - 17) in the serum using enzyme - linked immunosorbent assay (ELISA), the study included test phagocytic cells on phagocytosis (coefficient of phagocytosis) and the total and differential count of white blood cells .A total of 100 patients with bronchial asthma (68 females) and (32 males) whose age lies between 17 - 62 years have enrolled in this study. DNA was extracted and RFLP - PCR was performed by using primers specific for the gene IL - 13, the results showed the presence of mutations in a48 sample out of 100 patients with asthma at site 1112C/T after using restriction enzyme BstUI. the statistical analysis showed correlation between the occurrence of the disease and the emergence of mutation (C / T) in the promoter region of IL - 13 gene when compared with the healthy control in population of Thi - Qar province .When it was compared the patient group with healthy control group there was a high significant increase (P ≤ 0.001) in serum IgE, IgG of patients with asthma compared with healthy control group. And no significant difference in serum IgM of patients with asthma compared with healthy control group. Decrease coefficientphagocytosis was significantly (P ≤ 0.001) in all patients with asthma compared with healthy control group. Levels of interleukin (IL - 6, IL - 17) measured in serum of 60 a sample of patients with asthma, and in the serum of 20 samples from healthy control group. The results showed a significant increase (P ≤ 0.001) in the levels of these interleukins in the serum of patients with asthma compared to the control group.Also there was increased in the rate of counting the total of WBCs and differential cell lymphocytes, eosinophil, neutrophil, basophil, and monocyte (P ≤ 0.001) in patients with asthma compared with the healthy people in the control group.

Abstract: Burn injuries are considered as health problems that may sometimes lead to rapid death. Bacteria are considered as the most important causes of microbial infection associated with burns. In present study, 75 clinical samples were collection from patients with burns for the period from October 2015 to June 2016 from the lobby burns in Sadr Teaching Hospital in the Maysan Governorate, these burn swabs revealed 56 bacterial isolates, 41 (73.21%) were Gram - negative bacterial, distributed of (35.71%) Pseudomonas aeruginosa, (28.57%) Klebsella Pneuomonia, (3.57%) Escherichia coli ,Enterobacter (5.35%). On the other hand 6(10.71%)were Gram - positive bacterial. out of 75 burned swabs, 84% revealed a single pathogens and 16% shown a mixed bacteria. On the other hand, Antimicrobial susceptibility for the bacterial burn isolates revealed that P. aeruginosa was resistant to routine tested antibiotics, like Amoxicillin, Gentamycin and Tobramycin in 100%, While was resistance to Ciprofloxacin 85%, while most P. aeruginosa was sensitive to Ceftizmiden in 50%. Results also showed that Staph. aureus was resistant to Gentamycin, Tobramycin, and Levofloxacin in 50% respectively.Depending on the rate of injury burns microbial and resistance to antibiotics used, p.aeruginosa and Staph.aureus isolated from the burnswere chosen and study their role in the events of infection, experimental burns, and for this purpose has been the use Albino mouse male as a model for a pilot study for pathogenesis and progress associated with the infection of the disease bacterial burns. (33) male mice were divided into tow groups, the first group(24) mice were burned (deep dermal second degree) and infection by 0.2X108 cfu kg of elected isolates, the route of infection was subcutaneously and scratching within burned area. In the second group six were infected without burn, which was considered as positive control, while in the thirdgroup three mice were burned and injected by 0.2ml of normal saline and consider as negative control .the first group was subdivided into two subgroups (12) mices for each burn dominant pathogens, then divided into subgroups each of six mices and following up (3,7, days intervals post infection process). P.aeruginosa burned mice group, shown skin infection more progressive and more severity in comporning with group infected by Staph. aureus, In addition, they were significant increases in the body temperature of all infection burned mice group(p.value)compared with those pre - infection process. Reisolation of bacteria from infection mice organs revealed, that high percentages in experimental p.aeruginosa burned model comparison with Staph. aureus.Diagnosed bacterial isolates by API 20and Vitek compact system, in addition to molecular diagnostics using PCR technique for the detection of 16S rRNA gene, All isolates showed a positive result of this gene. The amplified 16S rRNA gene seguence was compared with the seguence in NCBI seguence database.the bacterial strain identified as P.aeruginosa EPSI. This study reflects the usefulness of sequence analysis of the 16S ribosomal RNA gene in identifying bacteria and determining bacterial diversity. Various techniques that are based on utilizing the 16S rRNA gene are discussed. Of critical importance is the use of massively parallel sequencing to study bacterial diversity. Through massively parallel sequencing which is replacing traditional methods of bacterial identification; various bacterial habitats are surveyed to compile their species compositions.

All those individuals were suffering from diarrhea and abdominal pain. This study included the microscopic identification of Entamoeba Spp. using direct wet amount and concentration techniques in order to diagnose both Trophozoite and cyst stages of the parasite. The result revealed that 1050 (26.86%) of the collected samples were infected with Entamoeba Spp. Out of these infected samples, 80 were randomly selected for further confirmation by conventional PCR and 18S rRNA. Using this method, 28 (35%) was recorded to have Entamoeba Spp. Positive samples from conventional PCR were further examined by Nested PCR for species specific identification. The result of this method showed the presence of two species, E. histolytica (39.29%) and E. dispar (39.29%).Positive samples for molecular examination (28) were then examined by Real time PCR in order to verify and confirm the molecular results. Two probes were used, Histolytica - 96 Tfor E. histolytica and Dispar - 96 T for E. dispar. A significant difference was observed between two methods. E. histolytica was found to be higher percentage followed by E. dispar and then Entamoeba Spp., 53.57%, 39.29% and 7.14% respectively. The Real time PCR reported mono - infection with E. histolytica in 45.5% and with E. dispar in 27.2%, whereas reported mixed infections by both parasites in 27.3%. Red blood cells (RBCs) were detected in 80% E. histolytica positive samples and in 54.55% E. dispar positive ones.The environmental factors and their correlation with Entamoeba Spp. prevalence were also included in this study. The infection prevalence based on the seasonal variation showed significant differences P≤ 0.05. Summer recorded the highest infection prevalence whereas the lowest was in the winter, 37.06% and 14.14% respectively. Regarding the infection in age groups, the highest percentage (30.5%) was recorded in under 3 years old group and the lowest (17.13%) was found in above 10 years old one. However, no significant difference P≤ 0.05 was observed between these age groups. Furthermore, no significant differences were recorded betweenpatient’s sex. Entamoeba Spp. infection (37.98%) appeared to be higher in children who belong to families with low standard of living compared to those who are from families that earning a higher income (10.11%). A Similar pattern was found in Entamoeba Spp. prevalence based on the number of the patient’s family members. Higher prevalence and significant difference were reported (39.95%) in patients who belong high family member (above 10), compared to those from 3 - 5family member (8.54%).One hundred and fifty blood samples from infected children with Entamoeba Spp. and fifty samples from healthy children as a control were collected during the present study in order to observe the change in blood picture and parameters between two groups. Significant differences were reported in blood hemoglobin (10.16%) and volume of packed RBCs (34.7%) in the infected group compared to 12.34% and 39.10% in the control group. Total leukocyte count was found to be significantly higher in the infected group (11.3) compared to the individuals in the control group (3.37). Differential leukocyte count also showed significant differences in Neutrophils (6.92%, 4.03), eosinophils (0.61, 0.17), monocytes (1.19,0.93) and lymphocytes (2.19, 2.76) in infected and control groups respectively.

Abstract: This study included 3 stages. In the first stage, Toxoplasma gondii was isolated from aborted women placenta who visited Bent Al - Huda hospital and Al - Shatra hospital after confirmation of the prescence of parasite by impression smear method. Then parasite uspension injected 0.3 ml which contain 100 cyst intraperitoneally (174 rat) to 87 male and 87 female rats, inaddition to control group 30 rat (15 male and 15 female). After 10 days of injection, diagnosed the acute infection by Real - Time Poplymerase Chain Reaction(Real - Time PCR) and showed 97.70% (170 infected rat and 4 noninfected rat) , in male 96.55% (84 infected rat and 3 noninfected) ,in female 98.85% (86 infected rat and 1 noninfected) . After 2months of infection 84 animals (42 males and 42 females)were sacrificed, dissected (brain, testis and ovary ) were isolated to confirm the occurance of chronic infection with the using Real - Time PCR. The incidence of infection was 100% in brain males and ovary females and recorded 71.43% in testis and 90.48% in brain females. So diagnosed infection by impression smear method, identified the amount of DNA of the parasite T. gondii by using Real - Time PCR. The use of the remaining number of animals within the following experiments.The second stage included effect of experimental Toxoplasmosis infection and some drugs on fertility 168 rat (84 male and 84 female). Animals were subdivided into 6 groups for each group included 14 rat : (First group) non infected treated by DMSO, (Second roup) non infected treated by Sulfadiazine, (Third group) non infected treated by Pyrimethamine, (Fourth group) infected treated by DMSO, (Fifth group) infected treated by Sulfadiazine and (Sixth group) infected treated by Pyrimethamine.The current study results revealed prominent effect of T. gondii infection on the hormonal level in both males and females. T. gondii infection induced significant decline in Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH) and Testosterone levels in nfected male compared with non infected males treated by DMSO. Sulf. and Pyr. treatment significantly elevated the level of these hormones (P <0.01) in infected males compared with fourth group similar to levels its in first group. Toxoplasmosis in female rats significantly decrease FSH, LH, Estrogen and Progesterone levels in compared with first group, while treating of infected females with Sulf. and Pyr. didn,t improve the declined levels of these hormones in infected and noninfected females comparedwith fourth and first group, respectively.The study showed that Toxoplasmosis in male rats induced significant decline in the sperm count in the epididymal cauda, sperm viability and relative weights of male sexual organs with an increase in sperm malformation ratio in infected male compared with first group. Treatment with Sulf. and Pyr. in infected male significanthy elevated the sperm count and viability (P<0.05), compared with fourth group. Sulf. didn,t induced further significant changes, but Pyr. induced further significant increase in sperm malformation ratio in infected (P< 0.01) and non infected (P<0.05) rats. The study also revealed that Toxoplasmosis significantly decrease the relative weight of ovary and uterus compared with first group, while treatment with Sulf. and Pyr. increased the declined relative weight of the ovary and uterus in the infected females.Testicular histological section of Toxoplasmosis infected male rats treatment with DMSO showed vacular degeneration of spermatogonia and spermatocytes. The seminiferous tubules revealed sever degeneration, shrinkal, necrosis, hemorrhage. Seminiferous tubules lumen contained little amount of sperm with appearance of gaint cell, polymorphonuclear leukocytes and exfoliated cellular debris. Metamorphosis and disintegration of the tissue between the seminiferous tubules was also observed compared to the first group that showed complex histologically intact while testes sections of infected rats treatment Pyr. and Sulf. showed improvement by removing histocompatibility damage caused by the parasite infection.The epididymal sections of T. gondii infected rats treatment with DMSO showed infiltration of mononuclear and multinucleated gaint cell. Sections also showed hyperplasia of duct lining and contained tissue cyst of T. gondii. All these changes were improved in infected males treated by Sulf. and Pyr. Ovary sections of the infected females treatment with DMSO compared with first group revealed decreased primary and secondary follicle increased follicle atresia. Histological sections of ovary females showed in the fifth and sixth group to increase the number of primary and secondary follicles and decreased number of follicle atresia compared overian sections for the fourth group. Uterine sections of the infected females treatment with DMSO showed hypertrophy, increase endometrial thickness and myometerium, increase polymorphonuclear cell infiltration, fewer glands and congestion of blood vessels compared with first group. Histological sections for ovary females of the fifth and sixth group showed changes but less severe than is present in the fourth group.In third stage from studying Toxoplasmosis on fertility parameters of male and female rats, 84 rat(42 male and 42 female) which showed the results of the current study, when paired fertilized healthy females by males is infected and infected of T.gondii treatment with Sulf. , Pyr. and DMSO, and inversion, there is the effect of the parasite and used drugs the percentage of getting pregnant and pregnancy size and rate of embryos weight and placental weight and increase the proportion of fetal resorption and the proportion of early loss of embryos in fertilized healthy females by males five groups compared to the first group.Based on that conclude from the study that the infection of parasite T. gondii had negative effects on the fertility of male and female, and that all of thePyr. and Sulf. were not honest is the other of the impact on reproductive functions.

Abstract: A database - driven site can be almost any kind of site, but at minimum it is a step up in technical complexity from a brochureware site. In a website which is database - driven one, many pages that are shown on it, were generated and retrieved from a database call. That is Thi - Qar University information management system provides an easy and friendly graphical tools and simple environment for maintenance the university staff and its accounting information system. It would be used by all colleges, departments and research centers in the University. This web application has been made some primary web database driven website like HTML. The core web application database was developed by PHP. Actually, PHP is a server - side language, so that a developer will be giving an access to the web server that is hosting the website, and to everything that is stored and/or runs there. Most importantly, PHP is mainly used to build a website that sends data to web browser so the pages can display information from our database engine which is MySQL and save data as well. This project uses MySQL as a relational database management system working like a back - end tool.So, the proposed system is to keep and managing the University staff details from the beginning to the end of the job life that might applied for all progress, purposes and reporting of the work, and completed staff’s personal information. Also, it will have college details such as the faculty details, staffs’ details in all aspects, and the various academic administration to the faculty managed and operated by the college. In addition, it could help us to discover all the administrative actions that occur in the college, different reports and queries can be generated regarding to the many available options related to faculty of college, accounting, documentations, and also to the whole faculty. Proposed system has the potential to provide wide range of services for the staff record management system, financial system and scientific research plan at the university. In order to assist in the design and implementation of proposed system, we present an overview, softwarearchitecture and prototype implementation of our proposed system.

Abstract: E - learning is the use of IT in learning and teaching. This usage improved the quality of learning and teaching through facilitating access to resources and remote collaboration among teachers and students. E - Learning makes it easier to create and distribute learning materials, independently of geographical or time limits. It allows students to exchange information and participation in activities.There are many systems (software) development for management of E - learning (LMS). These systems provide tools for simulation the traditional learning, development and support the electronic learning.LMS provides many tools to create, manage the examination, evaluate the grades and spread question types.The general aim of this thesis is to develop the LMS that has been increasingly used having widespread in E - Learning in many countries. This system is "Moodle" which designed to supporting electronic learning.Moodle system is not satisfying conditions of the traditional exam copybook that is used in examination committees in Iraqi universities in terms of security and accuracy."Single view" report in Moodle system allows the teacher to edit grades of "Quiz" activities.Moodle system not provided question type in which the answering method is done through selecting word from a given text; this idea is a suggested product for the development of Moodle website in 2014 and doesn't have solution yet.In this thesis, we proposed three main proposals : 1. Development of Moodle system to use it in the examinations in Iraqi Universities through designing and implementation of new module named "Teacher view" to provide "The Electronic Exam Copybook" which simulated the traditional exam copybook that is used in the examination committees in these universities for assessment of student's answers. It also presents documentation of detailed information about student's attempt on examination and calculates the student's grades. This "Electronic Exam Copybook" satisfies all conditions of the traditional exam copybook in terms of security and accuracy. Also, the proposed module provides students' results in English and Arabic languages and manual of this module.2. Overcome of the weakness in "Single view" report in Moodle system.3. Development of Moodle system through designing and implementation of a new question type called "Highlight words" in this system. The idea of answering method to this question type is highlight word from a given clickable text.We used the following requirements to design and implement the proposals tools in this thesis : 32 bit windows7 operating system, 2.30 GHz Core i3 processor, router device, WAMP server, Moodle system (version 2.9) in English language, Mozilla Firefox web browser, Macromedia Dreamweaver 8 and First object XML Editor software

Abstract: Fractal Image Compression (FIC) is one of the lossy techniques. In order for fractal compression image to be encoded is partitioned into non - overlapping blocks called ranges. From this range pool creates a new array called domain pool, the data of domain is array produced from taking an average of every four (2x2) adjacent elements in the range array, the domain is divided into overlapping blocks. Each block in range pool should be matched with every large number of blocks in the domain pool in order to find minimum error and recorded its best IFS approximate. The decoder process applies the determined IFS transformations on any initial image, and the process is repeated many times until reaching the attractor. In this thesis, it presents reducing the long encoding time of FIC without making significant sacrifice in the quality. In addition to the traditional fractal compression method, four IFS coding methods have been tested.The first method is speed up encoding phase by using moment features of the domain blocks with threshold , this method it compute the moment features of domain blocks only , during the matching process, compares the ratio factor of domain block with threshold, then compute the scaling (s), offset (o) coefficients and minimum error between range and domain blocks, and storing the optimal IFS coding , the results of this method with lenna image (4x4) block size, (the encoding time = 50.29 sec), (compression ration= 4.57 ) ,(PSNR=24.04), (RTR=33.42 ). The second method is speed up encoding phase by using the entropy technique of the domain blocks only , during the matching process, compares entropy value of domain block with threshold, and storing optimal IFS coding , the results of lenna image(4x4) block size, (the encoding time = 95.47sec), (compression ration= 4.47 ) ,(PSNR= 24.08) and (RTR= 17.60) . In the third method it merges the entropy technique with moment features of domain blocks only , during the matching process, compares entropy value and moments ratio factor of domain blocks with threshold and storing IFC coding, the compression results of lenna image (4x4)block size , (encoding time = 100.90 sec), (compression ration=4.47) ,(PSNR= 24.11) and (RTR=16.66) , the flaw in this method is the encoding time of 16x16 partitioning more than 4x4 and 8x8 partitioning. In the fourth method speed up encoding phase by use moment features of the range and domain blocks, in this method it computes the moment features of range and domain blocks, during the matching process, if the moments ratio factor of range and domain blocks are equal then compute scale(s),offset(o) and error (R) .storing best IFS coding. the results of lenna image(4x4) (encoding time = 114.02 sec), (compression ration= 4.47) ,(PSNR= 24.43), (RTR=14.74), the flaw in this method is the encoding time of 16x16 partitioning more than 4x4 and 8x8 partitioning. Matlab R2008a was used as a program to designed and implemented to achieve the coding and testing tasks. The environment used for our tests is a single PC with processor (core i3 CPU 2.53GHz) and 4.00 GB RAM .

Abstract: Cloud computing considers an important paradigm that provides services and dynamic virtual resources to the consumers over the internet.One of the main challenges and important fields for research in the cloud computing environment is load balancing. So the main goal of this thesis is to establish an effective load balancing algorithm for task scheduling. In cloud computing environment, the demands are executed into the virtual machines (VMs) and in the execution, it must be avoided a situation some of the resources are under loaded states while there are resources overloaded or heavy while achieving less the execution time of the tasks andresponse time. In this thesis, we present the Load Balancing Decision Algorithm (LBDA) which aims to achieve load balancing for reducing the : Total completion time (Makespan), Response time and Total execution time of tasks in cloud computing environment.The mechanism of LBDA is based on three functions, first : calculating the virtual machine capacity, virtual machine load then determining VM states (Under loaded, Balance, High balance, Overloaded) based on comparing VM capacity, VM load and using three thresholds : threshold upper; threshold fair; and threshold lower. Second : estimating the time required to complete executing the task in each VM. Finally, making a decision to distribute the tasks among the VMs based on VM state and task time required. Where checked task time required into VMs under states and selecting the fastest VM, when there are more than one VMs have the same time to complete a task, LBDA assigns a task to VMs which has the largest capacity. When all VMs become (Balance or High balance) states, the tasks are distributed between VMs depending on the fastest execution. The proposed LBDA was compared with Max - Min, Shortest Job First and Round Robin algorithms. We applied many experiments with various VMs’ capacity and : A different number of tasks on a different number of VMs, The same number of tasks on a different number of VMs, and A different number of tasks on a different number of VMs.The performance evaluation results implemented in cloudsim toolkit 3.0.3 and the experiments demonstrate that our proposed LBDA outperformed to other algorithms by reducing the completion time of tasks, response time, andtotal execution time of tasks.

Abstract: Cryptosystems becomes an increasingly important feature as the most reliable tool in network and information security. However, while there are many forms of cryptosystems exist today a weak link of all systems is the secure management of the cryptographic key. And as a result of the growing interests in biometrics a new field of research has emerged, which is called "biometric cryptosystems". Within biometric cryptosystems the advantages of biometric authentication are introduced to generic cryptographic key management systems to enhance security.This work proposes a scheme to bind a cryptographic key with the face biometric by combining correlation filters based biometric recognition with a biometric key binding scheme with providing the variation tolerance, discrimination and security which are the most important requirements that apply to a cryptographic key retrieval using a biometric. In the proposed scheme the cryptographic key is generated independently of user's face image using Pseudo - Noise generator to produce a unique and long enough key (128 bits) for each user then this key is linked to the face image only through a secure block of data known as the 'protected record'. The correct key will only be derived via the interaction of this protected record with the correct user's face image during a live authentication process. The resultant key may be used in a system as cryptographic key or as a personal identification number (PIN) to overcome the need to carry, store, or remember keys for cryptosystems or any other application that are used (PIN).The proposed scheme performance has evaluated using FACE 94 facial database. The performance rate reached to 100% which is a perfect result for practical applications. The proposed scheme is implemented using (MATLAB 2008). It is executed for testing purpose on computer with processor of 1.80 GHZ dual core, i3 under Microsoft Windows 7 operating system.

Abstract: تم تصميم هذه الدراسة للتحقق من دور جينات الـ Glutathione - S - Transferase (Mu - 1) gene و(Theta) - 1 Glutathione - S - Transferase ومدى مساهمتها بخطر الاصابة بمرض الربو القصبي في محافظة ذي قار. حيث شملت (105) شخص مصاب بالربو باعمار من (20 - 69) سنة كان | This study has been designed to investigate the roles of the gens GSTMI and GSTTI the extent to which they contribute in asthma at Thi - Qar governorate. The study has been conducted on (105) patients with asthma whose ages from (20) to (69) years. (20) of them are males and (85) are females, and (110) are healthy with no infection of asthma or any sickness of respiratory system as a control group of the same ages, (60) of these are males and (50) are females. Blood samples have been collected from both groups in ampoules with EDTA and stored under temperature ( - 20) until they are used in getting the DNA from the groups. The genes GSTTI, GSTMI, and Albumin have been enlarged as internal control employing Polymerase chain Reaction (PCR). Some dangerous aspects of this disease have been investigated, the results showed that the disease in the urban areas (85. 71 %) higher than it rural areas, and Asthma among females is (80. 95%) higher than males. The results also indicated that asthma in ages (50 - 59) is more than other categories; it is (34.28%). The majority of patients are smokers with (63.80%). The study revealed that (73.33 %) of the patients have a family history with the disease while (26.66 %) have not. Statistical analysis showed that the loss of the gene GSTM1 is about three times in the patients more than the case in the control group. (OR=2.90) , while the loss of the gene GSTT1 is five fold more than it compared to the control group (OR= 5.55). The results indicated a significant effect of the loss of the two genes in having asthma in the urban and rural areas, it is six times and a half larger in the urban areas compared to the control group of the same area. Asthma probability is ten times more in the case of the loss of both genes in the rural areas compared to the control group in the same area. And no significant difference has been discovered when gene patterns of patients in both areas. The results also indicated that the probability of having asthma in male patients is two times and a half as many as it in the females when the gene GSTM1 is lost compared to the control group. While the same probability is eleven times in the case of the loss of both genes in the females as many as it the control group. The loss of Missing the gene GSTT1 is three times in the male patients and five times in the females compared to the two control groups. The results indicated significant differences when gene patterns of males and females are compared in the case of the loss of both genes. The statistical analysis indicated that the loss of both genes in the smoker patients contributes 17 fold in the probability of having the disease compared to the control group. While the probability increases four times approximately in the nonsmokers when the gene GSTM1 is lost compared to the control group (OR=3.77; 95% C1=1.69 - 8.407). No difference has been noticed in the gene patterns of the smoker and nonsmoker patients. The results indicated that the loss of both genes has been in all the age categories. No significant differences have been noticed among the gene patterns between the patients of less and those who are more than 50 years. Asthma probability has been found 7.77 times more in the case of the loss of both genes in the patients who have a family disease history compared with the control group. The asthma probability is twice when the gene GSTM1 is lost in those patients who do not have a family history disease compared to the control group. Upon comparing the gene patterns of patients according to the family disease history, there has been an effect of the loss of both genes and having a family disease history on the probability of asthma, it is almost six times when both genes are lost. The results indicated that the probability increases three times in the loss of the gene GSTT1 in the educated patients compared to control group. The probability also increases seven times when both genes are lost in the uneducated patients compared to the control group. When comparing the gene patterns of patients according to levels of education, significant differences between the educated an uneducated have been approximately twice in the loss of the gene GSTT1.

Abstract: تضمنت الدراسة الحالية تحضير وتشخيص قاعدتين من قواعد شف، حضر الليكاند الاول L1 من تفاعــل 2 - هيـدروكسي - 1 - نفـثالديهايد مــع الـسلفاميثوكسازول، وحضر الـثانـي L2 مـن تـفاعــل 4 - استميدوبنزالديهايد مع 4, 3 - داي امينو تلوين. شخص الليكاندان باستخدام ت | The present work includes a preparation and characterization of two schiff bases compound, the first from (L1) reaction of 2 - hydroxy - 1 - naphthaldehyde with sulphamethoxazole, and the second from (L2) reaction of 4 - Acetmidobenzaldehyde with 3, 4 - Diamino toluene. These compounds were characterized by the Infrared (IR) Spectroscopy, Nuclear Magnetic Resonance Spectroscopy (1H - NMR), Mass Spectra, and the results were virtually identical to what is expected. It has been determined LD50 for the two ligands - after dissolved dimethyl sulfoxide DMSO - and account for them safe therapeutic dose, reaching 0.14 g / kg and 0.24 g / kg, respectively. In order to see the effectiveness of the two ligands on the parasite compared with the infected group and treatment with a drug metronidazole, these two ligands have been administered orally the therapeutic dose each separately on two groups of mice which infected by the parasite Entamoeba histolytica. Three other groups of mice that non - infected have been also administered separately with the parasite first and second ligands and dimethyl sulfoxide, to see some of the side effects of these three compounds in comparison with the two groups of positive and negative control. At the level of probability (p ? 0.05), the results of statistical analysis show a significant variation, remarkable inhibitory effect of the number of cysts that reached the less impact to the second ligand rate about 2.9. in the seventh day of the injury and treatment. In the fifth day of the injury and treatment, the highest inhibiting effect of metronidazole was at a rate of 0, while in the seventh day of them, the first ligand was a compromise in effect, amounting to at a rate of 1.1. The Histological study of tissue of the cecum, liver and spleen showed a normal state for a negative control, and an occurrence of severe tissue changes in a positive control. In the cecum tissue, the mucosal was thin, and there were crashes in the crypts of Lieberkühn, with infiltration in inflammatory cells, as well as the expansion of the cells lining the crypts, and the disappearance of or crash submucosal layer, as well as severe hemorrhage in muscularis, and thickening in serosa. There was severe congestion of the blood vessel which was observed in liver tissue, as well as thrombus which appeared attached to the wall of the blood vessel, and infiltration of inflammatory cells out of the blood vessel toward the hepatic tissue, especially macrophages and eosinophils. It was also noticed the disappearance of hepatic architecture with degeneration of the liver cells and a clear sinusoids expansion. In addition to vacuolation of liver cells, that the tissue sections showed, with the occurrence of bleeding along the hepatic tissue. The changes in the spleen tissue represented in the occurrence of severe bleeding on the length of the lymphatic tissue of the spleen with infiltration of inflammatory cells, especially macrophages, and the happening of megakaryocytes. There is a remarkable improvement could be noticed in each tissues of cecum, liver and spleen of the infected groups and treatment with metronidazole and the first and second ligands. The improvement ratios were close to some extent : in the treatment group with metronidazole there was observation in tissue cecum to the occurrence of the four layers of its component, and the happening of a little bleeding which, with infiltration of inflammatory cells, and this is roughly similar to what shown by histological sections of two treatments by the first and second ligands. The liver tissue of the group treated with metronidazole showed the occurrence of radially arrangement obviously hepatic cells around the central vein, and liver cells with nuclei appeared clear and centralized with esinophilic cytoplasm, and hepatic cells proliferative as some binucleated hepatocytes, with a simple expansion to sinusoids and the proliferation of kupffer cells, the treatment groups with two ligands marked by the presence of a small clot within the central vein of the liver as well as reported in the treatment group with metronidazole. Tissues sections of the spleen tissue of infected mice treated group by metronidazole showed a clear proliferation of white pulp, which appears containing arterioles clear, white pulp is also surrounded by proliferation red pulp. And showed tissue sections of the group of infected animals and treatment by the first and second ligands as well as the proliferation of lymphocytes, with the presence of megakaryocytes.Showed the three groups non - infected by the first and second ligands and dimethyl sulfoxide, the lack of side effects on each of the cecum tissue, liver and spleen, except for a very simple infiltration of inflammatory cells from macrophages in the cecum of the group treatment by the second ligand
