المستخلص: Endometriosis , a chronic inflammatory autoimmune disease, is among one of the most challenging of the 21st century that affects women in reproductive age. Seventy five consecutive married women endometriotic patients with age range (25 - 40) year were enrolled in this study , divided into three groups , the first included twenty five newly diagnosed endometriotic patients ( without any treatment) , the second consisted of twenty five endometriotic patients who were treated with zoladex for 3 to 5 months , the third involved twenty five patients with recurrent endometriosis (post treatment of zoladex) for one to two years ago. Patients groups were compared with two matched age and sex control groups , control group included twenty five healthy women while pathological control group involved twenty five women suffering from infertility caused by gynecological disorders not linked with endometriosis. The present study highlights the role of some morphological characteristics (BMI and W/H) , immunological / inflammatory aspect (Interleukin - 36 ? , Angiopoietein - 2 , Tumor Necrosis Factor - ? , Immunoglobulin G , Immunoglobulin A , Immunoglobulin M , Sialic acid ) , oxidative aspect (Total Cholesterol , Triacylglycerol , High Density Lipoprotein cholesterol , Low Density Lipoprotein cholesterol , Very Low Density Lipoprotein cholesterol , Paraoxonase - 1 , Ceruloplasmin ) and hormonal aspect (estrogen) in the pathogenesis of endometriosis. …………… Results have revealed that endometriotic patients have approximately a normal BMI and lower than pathological control group, but it was increased in patients under treatment with zoladex. A greater W/H ratio was associated with both endometriosis and pathological control group , while W/H was approximately not affected after treatment with zoladex. The present study have reported for the first time a positive relationship between IL - 36? , Sia and endometriosis. Those parameters could be considered novel biochemical markers in endometriosis because their levels were higher in sera of endometriotic patients without treatment compared with control and pathological control groups. Moreover , Ang - 2 appears to be a good biochemical marker in endometriotic patients. Hence, Ang - 2 levels were higher in sera of endometriotic patients compared with control and pathological control groups In contrast high levels of TNF - ? are associated not only with endometriosis but with pathological control group also. IgA and IgM could be used as possible biochemical markers for endometriosis. The present study is the first dealing with zoladex action on depressing IL - 36? , Ang - 2 , Sia while TNF - ?, IgG , IgA, IgM were decreased under treatment with zoladex. The present study have also suggested that TC and LDL - could be used in diagnosis of endometriosis , HDL - c levels were lower in patients without treatment compared with control and pathological control, but elevation obsereved under treatment with zoladex. PON - 1 activity was low in sera of patients while it was increased after treatment. Furthermore , this is the second study that proves a positive relation between CP and endometriosis and the first dealing with zoladex role on decreasing CP level in endometriosis. Lastly , estrogen was higher in endometriosis compared with control and pathological control groups , while it was decreased by zoladex action

[ Mo( N2ph - (NO2 )2) (S2CNEt2)3 ].The study of the kinetics of chemical decomposition for these chelates complexes by using irradiation of these complexes solution, by using a mono wave light (? = 365nm) and temperature (25?C) for (60 min) in ethanol solvent. The result for all complexes were that the order of photochemical decomposition was first order reaction. As well as the rate constants of photo decomposition reactions (kd) were calculated by observed a spectral changes during irradiation process. To know the best conditions for decomposition of these complexes, it is necessary to study the effect of several factors on photo chemical behavior for complexes which included : Effect of concentration of complexes, where five concentrations of complexes have been studied and found that the highest decomposition rate have observed at lowest concentration (2.5x10 - 5M). In addition, study the impact of change in intensity of light on decomposition rate. The result was when the light intensity increase, rate of complexes decomposition also increased. Also study a decomposition of complexs at temperature range (25 - 40?C). The result was when increasing temperature, the rate of complexs decomposition was increas, also the values of activated energy of all complexes where calculated and the results where show in the table : Activated Energy (kj / mole) Complex24.808 B122.971 C120.209 B217.778 C2 Also study effect of pH value at ranging (3 - 11) and found that the rate of the complexes decomposition increased when pH of solutions decreases. The effect of four alcoholic solvent were studied such as (methanol, ethanol, 1 - butanol and isopropanol), and found that the highest decomposition rate of these complexes achieved in Methanol, while the lowest decomposition rate of these complexes achieved in Isopropanol. In addition study the effect of each of nitrogen gas, oxygen gas and the atmospheric air on the rate of complexes decomposition and compile the results with recorded results in normal conditions, the highest decomposition rate observed in presence of oxygen gas and the lowest decomposition in presence of nitrogen gas. The mechanism of photo chemical decomposition of these complexes has been interpreted by spectrophotometric technique, were the conclusion that have been obtained that there is (redox - reaction) happening in these complexes and the output of processes of homo cleavage of bond (M - L) that leading to reduction of metal ions and oxygenation of ligand and formation free radicals.

المستخلص: Mammaglobin A is a member of the superfamily of secretoglobins. Its expression is highly specific for mammary tissue and has been shown to be overexpressed in breast tumor tissue, indicating that mammaglobin A might confer a growth advantage to mammaglobin A - expressing tumor cells. The present study was undertaken to develop the mammaglobin A as a serum biomarker for the early detection of breast cancer, and breast cancer patients follow up after treatments. This study had taken ten months, it involved 84 patients with age ranged 15 - 74 years who had diagnosed with either stage I to III breast cancer or benign lesions of breast at certain Iraqi hospitals and breast cancer centers, and a total number of 10 apparently healthy individuals, with comparable age range of patients as control group.Ten ml of venous blood was collected from studied groups in order to be used for measuring estrogen and progesterone levels, Reverse transcription polymerase chain reaction (RT - PCR) test for detection of their serum m - RNA mammaglobin A existence, and serum mammaglobin A levels using Enzyme - Linked ImmunoSorbent Assay (ELISA) technique. Demographic study revealed that most cases enrolled in this study were women within their reproductive age 25 - 44 years old. Distribution of patients according to age group, marital status, and lactation status showed no statistically significant association (P>0.05) with any of these variables, in all comparison.The hormonal study states that elevated levels of estrogen were observed in 52 (62%) patients, also decrease in progesterone levels were observed in 50 (59%) patients out of the 84 cases studied. This indicate a highly significant SUMMARYassociation (p < 0.01) between breast cancer risk, elevated estrogen levels, and decrease in progesterone levels. Mammaglobin A protein was detectable by ELISA in 100% of breast cancer patients (65 case), and not in any benign tumor patients (19 case) nor healthycontrol women (10 females) which indicate the highly specificity of ELISA test (P<0.01) for measuring mammaglobin A levels in patients serum. With high concentration of protein in sera of women with late stage of breastcancer compared with a low protein concentration in sera of women with early stage of breast cancer. By applying a statistical analysis on the result it was found that serum mammaglobin A ELISA test is highly significant (P<0.01) for, differentiation between patients with metastatic breast cancer and patients with early diagnosed breast cancer. In this work, SCGB2A2 gene which coded for mammaglobin A was detected in 64 out of 65 breast cancer cases, but not in the benign or healthy individuals indicating its high specificity as a marker gene (SCGB2A2) for cells derived from mammary glands. A statistical analysis was made for comparison between the three groups, E - Malignant Tumors \ Early Stage, L - Malignant Tumors \ Late Stage, and B - benign, (E, L, and B) which show that the results of molecular study of mammaglobin A detected by RT - PCR is statistically high significance (P<0.001) when used for the differentiation between E group and B group, also between L group and B group. The results showed that mammaglobin A can become an important tool for detecting primary and metastatic breast cancer, and predicting disease outcome.

المستخلص: تناولت الدراسة الحالية دراسة تشريحية مقارنة لتسعة مراتب من العائلة القرعية Cucurbitaceae المستزرعة والبرية والتي زرعت في الحديقة النباتية لكلية التربية للعلوم الصرفة ابن الهيثم والمراتب هي : 1 - Citrullus colocynthis Schrad2 - Citrullus vulgaris Schrad3 | The present study included comparative anatomical study for nine taxa of Cucurbitaceae family for cultivated and wild types, which were planted in the garden of College of Education for Pure Sciences/ Ibn Al - Haitham. These taxa included : Citrullus colocynthis Schrad, Citrullus vulgaris Schrad, Cucumis melo Linnaeus, Cucumis melo var.flexuosus Naudin, Cucumis sativus Linnaeus, Cucurbita maxima Duchesne, Cucurbita pepo Linnaeus, Lagenaria siceraria (Mol.) Standl, Luffa cylindrica (Linnaeus) M. Roem. This study focused on some the anatomical characterization as compared study for the first time to these taxa in Iraq. This study included the features of ordinary epidermal cells, leaves petioles, stems, pedicles and sepals of the studied taxa. The results found the appearance of stomata in the stems and petioles in straight line as adjacent planar shape to the epidermal cells and not scattered as found in the leaves, this result was seen for the first time in the current taxa. Furthermore, the stomata have been shown in pedicel and sepals in same type as the stomatal complexes in leaves. The importance of phenotypic variation for the length and types of eglandular trichomes and the presence or not of glandular trichomes were found to carry out the role of indumentum in the different isolated taxa. Additionally, this study included the examination of the cross sections of the roots and also exposed the constituent tissues of it, the variation in the thickness of epidermis, cortex, vascular cambium as well as the arrangement of phloem cells have an important role in the studied taxa. The cross sections of stems, leaves petioles and pedicles showed shape and studied a significant role in the studied taxa and split them into groups.Moreover, this study concluded that the following of above sections from the outside into the inside has an important role to find out their constituent tissue. Thus the results of the study clarified the importance of epidermis tissue through the explanation of the outer and inner tangential walls of their cells and the variation in their dimensions, thickness and kind of stomatal complexes; therefore it has been given the importance of those features in the studied taxa in this study. Cortex tissue showed an extension of angular collenchyma and chloronechyma from stem to pedicel and have shown variation in the thickness in these two layers which was useful in the classification of studied taxa. Vascular tissues differed in the shape of vascular bundle, the number of rows and xylem units and the arrangement of the internal phloem, and all of those characteristics have helped in the studied taxa. In addition, the vascular tissues helped to find their arranged in the stems and found as vascular cylinder shape, while in the petioles and pedicel shown as vascular ribbons were which took the shape of sections petioles and pedicel. The medullar cells and medullary rays have been studied and also their similarity in the morphological characterization and function. Moreover, the anatomical features of the vertical sections of the laminae of leaves in mesophyll tissue have been examined, in the thickness of palaside and spongy layers in midrib, the variation in number and arrangement of vascular bundles have an important role in the studied taxa. In the current study, the ordinary and petal leaves venation and the type of venation have been studied in the studied taxa. Moreover the vertical sections for sepals were examined and also their similarity with laminae of leaves which was useful for studying the constituent tissues of some parts such as pedicel and sepals and anatomical features; and all of the studied characterization helped to study the vegetative parts through following them in studied taxa.

المستخلص: The morphological and histological structure of digestive tract in one species of Iraqi fish that resides in Iraqi inland fresh water (Liza abu) was studied. In this study used (43) fish were in different lengths, the gut of these fish have removed to study the relationship between the length of gastrointestinal tract and the standard body length as well as for morphological and histological study. The value of relative digestive tract length (RGL) was 2.9. Intestine was the longest part of the digestive tract, the average length of intestine was (32 cm). The shape of the folds of the mucous membrane lining the walls of digestive tract showed some differences in different parts of digestive tract, in esophagus the folds were longitudinal running along the wall and it was straight, unbranched and the mean of their number was (9 - 8) folds. In the stomach the folds were longitudinal and (7 - 6) in their number, they were branched into fingerlings structures. In pyloric caeca, anterior and posterior part of intestine and rectum the folds were fingerlings in shape, unbranched and their number were (20 - 19), (27 - 26), (25 - 23), (19 - 18) respectively. Histological study was shown that the wall of the digestive tract is consist of four major coats, from the inside to the outside they were as follows : Tunica Mucosa which characterized by its clear three parts, epithelial tissue, lamina propria and muscularis mucosa. Epithelial tissue in esophagus was thick stratified squamous epithelium, in stomach was thin simple columnar epithelium and gradually increase in length in each of pyloric caeca, intestine and rectum and it was simple columnar epithelial tissue. Mucous which is secreted in esophagus is made of a large proportion of neutral and acidic mucopolysaccharide, while the mucous secreted in the cardiac stomach consist of a large proportion of neutral mucopolysaccharide and less proportion of acidic mucopolysaccharide, either, in the pyloric stomach is consist of very small proportion of both neutral and acidic mucopolysaccharide, in pyloric caeca mucous consist of a small proportion of neutral mucopolysaccharide and less proportion of acidic mucopolysaccharide, and the mucous secreted in an anterior, posterior parts of intestine and rectum consist of small proportion of acidic mucopolysaccharide and large proportion of neutral mucopolysaccharide. Lamina propria consists of connective tissue containing capillaries and lymphoid cells and it represent the basis of the folds, in the cardiac stomach it contains simple tubular glands. Muscularis mucosa characterized by the presence of muscle fibers that are not continuous, the higher thickness of this layer was in pyloric stomach. Tunica Submucosa consists of connective tissue that contains capillaries, the higher thickness of this coat was in the stomach and less thickness of this coat was in the rectum. Tunica Muscularis consists of two layers of smooth muscle fibers, the internal layer has a circular arrangement, the external layer has a longitudinal arrangement in stomach, pyloric caeca, intestine and rectum. either in esophagus tunica muscularis was arranged in inverse manner. The circular and longitudinal muscle fibers in esophagus were skeletal muscle fibers, and they were smooth and non - striated in stomach, pyloric caeca, intestine and rectum. the higher thickness of this coat was in the stomach and less thickness was in the rectum Tunica Serosa is present in all regions of digestive tract.

No clinical autoimmune manifestations such as arthralgia or cutaneous vasculitis were reported in any patients. Based on direct skin smear examination and serum samples analysis, the patients were distributed into two clinical groups : 30 patients suffering from cutaneous leishmaniasis and 30 patients suffering from visceral leishmaniasis patients.The presented study aimed to confirmation of diagnosis cutaneous leishmaniasis depending on direct skin smear and visceral leishmaniasis based on indirect immunofluorescent assay test IFAT, then investigate the association of IgG autoantibodies against some antigens, especially : nuclear antigens, like : ds - DNA, nucleosome, histones, SmD1, PCNA, ribosomal P0, SS - A/Ro60kD, SS - A/Ro52kD, SS - B/La, CENP - B, Scl70, U1 - snRNP, AMA M2, Jo1, PM - Scl, Mi - 2, Ku and against cardiolipin, in order to correlate the types of diseases presentation (cutaneous or visceral) with the presence of these autoantibodies in a sample of Iraqi patients.The study was reached to the following results : 1. The direct microscopically examination of skin smear in CL patients, showed positive results in 30 cases (40.0%) compared to 45 cases (60.0%) negative results, and was a significant difference at the level of (P?0.05).2. The anti - leishmanial antibodies by Indirect immunofluorescent assay test in VL patients, showed positive results in 30 cases (42.9%) compared to 45 cases (57.1%) negative results, and was a highly significant difference at the level of (P? 0.01).3. The age groups most affected in CL were 16 to 40 years, with high significant differences at the level of (P? 0.01) were observed when compared with the other age groups. As for patients with VL, who aged between 3 months to 9 years, they showed variable significant differences between age groups in female while there were no significant differences in male at the level of (P?0.01). The majority of patients were aged 3 to 4 years and they represent 9 (30.0%). The study result showed 16 CL patients (53.3%) have only one lesion, while 11 patients (36.7%) have 2 to 9 lesions and only 3 cases (10%) have ? 10 lesions in different sites of their bodies. There were elevated high significant differences at the level of (P?0.01) when compared between the groups. And 21 cases (70%) have infected for ? two months, and the remaining 9 cases get their infection for > 2 months duration. There were increased high significant differences observed at the level of (P?0.01) when compared between the groups. Dry lesions recorded superiority in 20 (66.7%) of the CL cases, and other 10 (33.3%) have been diagnosed as a wet lesions. There were elevated high significant differences observed at the level of (P?0.01) when compared between the two types of the lesion. And The upper limbs were the dominant site of lesions in the CL cases, 15 (39.4%) of the cases had their lesions in one or both hands, followed by the lower limbs in 11 (29.0%) cases and the less frequent site of infection was the face in only 4 (10.5%) cases and 8 (21.0%) cases common lesions. The results showed obvious high significant differences at (P? 0.01) between the groups.4. For the tests of the autoantibodies, the anti - ds - DNA antibody was positive only in one patients (3.3%) with CL of the total (30) patients, while tests of the rest 29 (96.7%) were negative, while in VL of the total (30) patients, 9 patients (30.3%) were positive and 21 (70.0%) were negative. The anti - ds - DNA in leishmaniasis patients were highly significant at the level of (P?0.01) when compared between the study groups. As for the anti - nucleosomes antibodies, it was positive in 5 patients (16.7%) and negative in 25 (83.3%) among patients in CL, while in VL patients, 16 patients (% 53.3) registered positive and 14 (46.7%) their result werenegative, the anti - nucleosomes antibodies in leishmaniasis patients were highly significant at the level of (P?0.01) when compared between the groups study. No score was recorded for anti - SmD1antibodies in CL patients, no one was positive 0 (0.0%) and all the 30 patients (100.0%) gave negative result for this antibody, while in patients with VL, the result showed 4 patients (13.3%) gave positive and 26 patients (86.7%) were negative, the anti - SmD1antibodies in leishmaniasis patients was significantly different at the level of (P?0.05) when compared between the groups. While the anti - SSA/Ro60kD and anti - SSA/Ro52kD, in VL patients, 9 patients (30.0%) scored positive results and 21 of the patients (70.0%) were tested negative for anti - SS - A/Ro60kD, but 7 patients (23.3%) were positive and 23 of the patients (76.7%) were tested negative for anti - SS - A/Ro52kD.

المستخلص: استهدفت الدراسة الحالية عزل وتشخيص الفطريات المستنبتة في اوراق نبات الاس Myrtus communis واختبار فعاليتها المضادة للاحياء المجهرية وفعاليتها الانزيمية. - اظهرت نتائج عزل الفطريات المستنبتة في 500 قطعة اوراق للحصول على عدد كلي للعزلات مساويا الى 99 عزلة ف | The present study was aimed to isolate and identify endophytic fungi from leaves of myrtle Myrtus communisand study their antimicrobial and enzymatic activities. - Results of fungal isolation from 500 leaves fragments revealed isolation of 99 endophytic fungi represented a total colonization frequency (CF) of 20.4%. These fungi were related to 23 species or isolates, where Aspergillus spp. prevailed over all others (11 species) with CF of 14% for all Aspergilli, Aspergillusniger and Aspergillusflavus showed the highest CF 7.2% and 3% respectively, other Aspergilli represented Aspergillusparvulus (CF 1.6%), Aspergilluscandidus (0.4%), Aspergillusraperi, Aspergillusclavatus, Aspergillusglaucus, Aspergillusornatus, Aspergillussclerotioniger, Aspergillusterreus and Aspergilluswentii were all showed CF of 0.2%.Other isolates fungi from leaves fragments were four morphologically different isolates of Penicillium with 0.4% CF for each. Additionaly, isolates of Cladosporium sp. (2%) and Cladosporiumcladosporoides (0.4%), as well as Cunninghamella sp., Drechsleraaustraliensis, Alternariaraphani, which showed 0.2% CF for each, Paecilomyces variotii (0.6|%), and different isolates of sterile fungi (White and Hyaline colonies) were also obtained. - Study the antagonistic activity of isolated endophytes using dual culture method against five plant pathogenic fungi(Fusarium oxysporum, Fusarium graminearum, Fusarium sp., Macrophomina phaseolinaandRhizoctonia solani)taking into account the percentage of inhibition of pathogenic fungi, results revealed variation of antagonistic activities between endophytes and pathogens. Different cases of antagonism were also appeared ranged from mycoparasitism of the endophytes on pathogens or vice versa, to competition between the two fungi and to the appearance of inhibition zone between them, this result may indicates the affinity of using some isolated endophytes in biological control applications against or controling fungal plant diseases. - Effect of ethylacetate extracts of culture broth of active endophytes shown in the last experiment against two bactria E.coli, S.aureus and the yeast Candida albicans using disc diffusion method, where filter paper discs were imprignated with different concentrations of fungal broth extracts. Results showed variation of inhibitory activity against bacteria with different endophytes, bacteria and conc. of the extract. Regarding the effect onC.albicans and filamentous fungi, most fungal broth extracts showed no inhibitory activity against yeast and no extract as well showed inhibitory activity on filamentous fungi. These results give indication thatbroth extracts contain antibacterial compounds. - Addition of 20% crude fungal broth of some endophytes to the culture medium showed significant inhibitory activity against filamentous fungi which did not respond to broth extracts, percentage of inhibition ranged between 0 - 77.08% and maximum inhibitory activity was shown by Penicillium sp. Isolate. These results give indication that some of crude filtrates contain antifungal compounds. - Analysis of broth extracts of some endophytes using TLC technique showed the content of extract of number of UV illuminated spots isolated on TLC pates having different Rf values, Bioautography showed inhibitory activity of some of these isolated spots against E.coli, S.aureus and the Filamentous fungus F.oxysporum. - Testing the extracellular enzymes activities of isolated endophyles on solid media, enzymes included amylase, lipase, pectinase, laccase, cellulase and protease showed variation in secretion of these enzymes, as well as, no endophytes showed the affinity of secreting all tested enzymes. Results also showed the high affinity of some endpohytes to secrete enzymes that could be use in multiple important applications after separation andcharacterizationof these enzymes.

المستخلص: Studies have linked FOXP3 and TGF - ? expression to the outcome of certain cancers. FOXP3 is a marker known to be expression in T - regulatory cells while TGF - ? is a secreted protein usually detected in the extra cellular matrix.The present study aimed at focusing on the identification of immune markers namely FOXP3 and TGF - ? with their expression patterns in lung cancer patients as a useful tool to predict disease progression.Also it is aimed to design molecular evaluation of m RNA expression of both FOXP3 and TGF - ? in peripheral blood mononuclear cells and bronchial (brush) cells of patients with lung cancer and benign lesions, using qRT PCR; determining the T - reg level in the peripheral blood employing the High Rsolution Melting (HRM) as a novel method to detect Treg - specific demethylated region (TSDR); molecular DNA analysis of somatic mutation of exons 3, 6, 7 of FOXP3 in patients with lung cancer tissue and benign lesions and immunohistochemical (IHC) estimation of FOXP3 and TGF - ?1 in T - reg and cancer cells in formalin fixed paraffin embedded(FFPE)lung cancer tissue and benign lesions.Blood samples were collected from 30 patients with newly diagnosed, non small cell lung carcinoma and 30 patients with benign lesions.Patients were recruited at The Specialized Surgery Hospital and Oncology Teaching Hospital/Baghdad.Samples from 16 apparently healthy donors were used as control during the period from June 2012 to June 2013. The samples preservation with TRIzol reagent were subjected to molecular study including RNA and DNA extraction; reverse transcription; RT - PCR; HRM assay and DNA sequencing were done in the Molecular Oncology Unit/Guys and ST Thomas? s hospital/ King College/London/UK.The expression level of FOXP3 was high in 16(61.5%)in lung cancer cases.A significant difference was noticed between cancer cases from one side and benign lesions or healthy control on the other side p<0.05.Mean of FOXP3 expression(fold change)was significantly high(2.64±0.09)in cancer cases than in benign cases(1.32±0.04)and healthy control(1.38±0.06)with p<0.05.A significant association between high expression level and >60 age and squamous cell carcinoma in cancer cases P<0.05.The expression level of TGF - ? was high in 16(61.5%)in lung cancer cases.A significant difference was noticed between cancer cases from one side and benign lesions or healthy control on the other side p<0.05.Mean of TGF - ? expression (fold change) was significantly high (6.27±0.56) in cancer cases more than healthy control (2.87±0.09) with p<0.05.The association was significant between TGF - ? expression level (high and low) and age>60in cancer and benign groups (p<0.05), while no significant association with gender and cancer types were noticed.For FOXP3 mRNA expression in bronchial brush cells, the result showed no significant difference between the mean fold change of malignant(3.57 ± 0.06) and benign(4.02 ± 0.06) patients. The low expression was predominated both in cancer and benign cases. No significant differences were found between FOXP3 expression (high and low) and age; gender ; cancer types..According to FOXP3 T - reg specific demethylated region detection, results showed that the mean percentage of FOXP3demethylation in lung cancer patients (4.32 ± 0.04) was significantly higher than in benign lesions (3.22 ± 0.02) patients andhealthy controls(3.33±0.04). A positive correlation coefficient with high significant, was found in the group of cancer samples (R² = 0.6653;r = 0.69;P : 0.0017)on correlating percentage of Treg and demethylation of FOXP3 from one side with its m RNA expression on the other side.In benign lesion group was(R² = 0.5334;r= 0.59;p= 0.0027), While in the control group a positive correlation but a weak significance was found (R²= 0.2383;r=0.28;P=0.0437).FOXP3 gene sequencing revealed high frequency of missense mutations c.715 GTA>CTA : V 239 L in 17 (94.44%) in malignant sample and non cancerous cases7 (87.5%)without statistical differences. Missence mutations were also detected in exone 3 in 3(16.67%) cancer cases and in 1(12.5 %) benign lesion.No missense mutations could be detected in exon 6. Intronic mutations and silent mutation were variable in three exons without statistical differences. Many cases of adenocarcinoma have shown multiple mutations either of missense or Intronic types. Missense mutations of exon 7 were correlated significantly with an age of 60?years. Exon 3 mutations were significantly associated with adenocarcinoma. Positive FOXP3 Immunohistochemistry (IHC) staining in tumor cells was associated with high missense mutations frequency 10(55.55%) in exon7, while in exone 3 was 2(11.11%). Negative FOXP3 IHC staining in the tumor cells was associated with seven missense mutations in exon7 and one (5.55%) in exon 3, in addition 4(23.53%) cases of the exon 7 missense mutations were associated with negative FOXP3 expression in lymphocytes.The result showed that FOXP3 by using IHC staining was positive in 21(70%) of nuclei of cancer cells, and 22(73.3%)in Treg infiltrates.The positive cancer cells and Treg infiltrates associated significantly with age>60 (p<0.05).No significant association was found withgender, cancer type, while there is association with moderate differentiation compared to poorly differentiation (p<0.05). High frequence of FOXP3 expression score 3 and high intensity were appeared in nuclear cancer cells compared to benign lesions cells, while Treg infiltrates with score 1 and high intensity was high frequency in malignant and benign.The result showed that TGF - ?1 by using IHC staining was positive in 25(83.3%) in the cancer cells and 21(70%) in stromal cells. No significant difference was noted between positive expression in malignant and benign lesions p>0.05.No significant association was noticed between positive cells expression and age, gender, cancer type and differentiation p>0.05. High frequency of TGF - ?1 expression score 3 and high intensity in malignant cells and benign. Also stromal cell expression score 3 and high intensity were predominated in malignant and benign lesions. The high and moderate intensity expression was more frequent in matrix surrounding cancer cells compared to non cancerous.Total agreement and kappa coefficient between FOXP3 and TGF - ?1were poor in malignant and benign epithelial cells and stroma, while the perfect agreement was between expression of TGF - ?1in stromal cells
