المستخلص: The current study was conducted for the period from September 2015 until August 2016 in college of Education for Pure Sciences - University of Thi - Qar, this study aimed to fallow the embryonic lung development and evaluate histological changes in embryos's lung development when pregnant mice treated with different doses of Dexamethasone (Dex) and evaluate Alpha - fetoprotein (AFP) levels were evaluated as an indicator for congenital malformations. Sixty pregnant mice were randomly divided into four groups and each group contain 15 pregnant mice. The members of each group were given specific dose of Dex and at different time periods, while the control group injected with a solution of Normal Saline 0.9%.All animals received doses used by tail intravenous injection until the end of the time periods specified .Blood samples were taken for the purposes of biochemical parameters account as well as the collection of samples for histological study .The treatment of animals under the same conditions were determined with a dose based on body weight, according to what was stated in the pharmaceutical constitutions where's the therapeutic dosage was 0.002 mg \2mg (0.1mg.kg from body weight ). We used another two concentrations from drug ,one less than the therapeutic dosage (0.05mg \kg from body weight) and another more than the therapeutic dosage (0.2mg \kg from body weight ).The results have showed that was a negative effects on mice embryo's body weights and the lengths increase with increasing of number and doses concentrations. The using of different doses of Dex also showed various changes in general external morphological features and congenital malformation in embryos of treated mothers included : Death of embryos ,placenta damage ,neural Tube Defect ,Trunk Torsion ,Headhemorrhage, Brain hypertrophy ,Liver Hypertrophy ,Letter C Shape Embryos, swelling ,Convoluted Tail ,Short nostril and limbs, curved head, Wrinkled skin ,Crooked pave ,Short toes ,Seal legs appearance, Oedema ,absent fingers and eyelids ,Tail congestion and Bulging eyes. Histologically microscopic examination showed histological changes with varied severity and appearing between different sub experimental group compared with the control group.Rapid elongation in lung bud, advancing in lung development, the lung asflower appearance, Loosely lung mesenchyme ,necrosis in lung tissue ,mucus hypersecretion, elongation in epithelial air ways,epithelial Hyperplasia ,mesenchyme looks as butterfly in appearance in some parts ,thinning of alveolar walls ,thinning of the interstitialmesenchymal lung tissue ,elongation of developing alveolar septa ,free alveolar septa. Alfa - fetoprotein (AFP) levels showed different concentrations value in correlation with congenital malformations .when the (AFP) value was high there were neural tube defects and advancing in the lung development while they were low in normal lung development and in brain hypertrophy.

المستخلص: 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.

المستخلص: 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.

المستخلص: 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 .

المستخلص: 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.
