المستخلص: In the present study , a total of 150 clinical samples were collected (50 samples of sputum ,50 swabs of gingiva and 50 vaginal swabs ) from patients visited Basrah general hospital and from the 1st specialized center of dental medicine in the city of Basrah . This study extended from January 2015 to May 2015. Samples were taken from males and females (except vaginal swabs where were collected from females only) .Their ages ranged from 6 - 70 years old. These samples were collected and cultured in a method monophasic - diphasic culture setup ( MDCS ) . Three types of Mycoplasma were isolated : Mycoplasma pneumoniae from sputum , Mycoplasma salivarium from gingival swabs and Ureaplasma urealyticum from vaginal swabs .These isolates diagnosed by biochemical tests and PCR. Mycoplasma spp. were isolated from 76 individuals out of 150 enrolled in this study, infection rate was 50.5% , 25 cases were diagnosed as M. pneumoniae (50%) , 13 cases were diagnosed as M. salivarium (26%) and 38 cases were diagnosed as U. urealyticum (76%).Mycoplasma was studied in related with two factors : sex and age . In this study, the Mycoplasma medium is modified , egg yolk was used instead of horse serum as source of cholesterol and also used two amino acids Arginine and Cysteine as well as urea ( when diagnosing U. urealyticum ) to support Mycoplasma growth. Besides that , thallium acetate was replaced by sodium benzoate , finally , magnesium sulfate was used as a sign of ammonia when diagnosing U. urealyticum.In this study , PCR technique used to diagnose species of Mycoplasma using ATPase gene ,16s rRNA gene and Urease gene .Sixty - eight isolates were identified by PCR technique , 25 of them were M. pneumoniae , 13 were M. salivarium and 32 were U. urealyticum.

المستخلص: The present study aimed macrobenthic invertebrats communites in three different aquatic environments southern Iraq. Eight stations were chosen for this purpose, Four of them distinction by being with running water and affected with the tide of Arabian Gulf,these include two stations on each of Shatt Al - Arab River (Al - Mohamadiat and Al - Salihia) and east part of Al - Hammar marsh (Al - Burgah and multaqaa Al - Mashab and Al - Sallal).the other four stations were not affected with the tide and located on the central marshes, two stations on each of Aum Al - Showaich marsh (Al - Sibitia and Al - Badria) and Al - Chebaeish marsh (Abu Sobat and Al - Sihaqee).The samples of water and sediment were collected monthly during the period from April 2014 to March 2015.Some environmental factors for each station were measured these include air and water temperatures, pH ,electrical conductivity, turbidity, dissolved oxygen, biological oxygen demand, total dissolved soild, total hardness, Calcium, nitrate , reactive phosphate, sulphate, total organic carbon and soil texture. The macrobenthic invertebrates samples which collected by Three replicates monthly for each station were isolated and identified,then densities and relative abundance were calculated.Some ecological indices such as diversity, richness, evenness, dominance, beta diversity and similarity indices(qualitative and numerical) were studied. Canonical correspondence analysis was adopted to evaluate the effect of the measured environmental factors on the occurrence and density of the studied macrobenthic invertebrates.The results showed that the variables of the stations were ranged as below : Air temperature (12 - 44)C̊ ,while the water temperatures (10.6 - 35)C̊ , PH (7.5 - 9.1), EC (2.07 - 13.7) mS /cm, Turbidity (4.2 - 199) NTU, DO (5 - 11.5) mg/l , BOD5 (0.3 - 3.5)mg/l , TDS(1245 - 10220)mg/l , TH (531 - 2928) mg/l , Ca+2 (80.2 - 320)mg/l , NO3 - (0.26 - 15.25) mg/l , PO4 - 3 (0.032 - 2.9) mg/l , SO4 - 2 (250 - 910)mg/l , and for sediments : TOC (9.3 - 22.5)% and soil texture ranged between sandy silt to muddy silt.The total number of recorded taxes were 80,representing by 16 species belonging to Annalida, 36 genus to the Aquatic insects (28 genus of them were first record in the middle wetlands), 16 species to Crustacea and 12 species to Mullosca. The species Pomacea canaliculata was recorded for the first time from Shatt Al - Arab river. The recorded taxes were classified according to its occurrence periods into four classes : dominant, fluctuated, less abundant and rare.The monthly density of each taxa of macrobenthic invertebrate and for each main macrobenthic invertebrate group in all stations was calculated. The results revealed that the densities were ranged from( 0 - 7115, 0 - 485 , 0 - 703 and 0 - 1199) ind/m2 for the groups of annelid, aquatic insect, crustacean and mollusca respectively. While the total density of all macrobenthic invertebrate groups was ranged between( 0 - 7367) ind/m2.The results of annual relative abundance for each main macrobenthic invertebrate group in all study stations referred that the value 66.3% was recorded for the annelids, while the lowest one 6.1% was recorded for the aquatic insects. On the other hand, the annual relative abundance for each main group in each station was investigated, and was ranged between (0.9 - 68)% recorded in Shatt Al - Arab river stations for the groups of aquatic insects and annelids respectively,( 0.4 - 67)% recorded in east Hammar marsh stations for groups of water insects and mollusks respectively, and (1 - 82)% recorded in Middle marshes stations for the annelids. The annual relative abundance for total macrobenthic invertebrate group in all stations was ranged from (2 - 27)% recorded in Al - Sibitia and Al - Sihaqee stations respectively. The annual relative abundance for the species and genus which recorded during our study revealedthat all highest values (94, 96.58 and 100)% were recorded for the species Limnodrilus hoffmeisteri in stations of Shatt Al - Arab River, east Hammar marsh, and Middle marshes respectively.The monthly relative abundance for main macrobenthic invertebrate groups in all station was studied. The highest value which recorded from Shatt Al - Arab river stations (Al - Salihia station) was reached 95.8% and recorded for the annelids, while reached 100% either in east Hammar marsh stations(Al - Burgah) for the mollusks and in Middle marshes stations (Al - Sibitia) for the crustaceans.Some ecological indices for each for each main macrobenthic invertebrate group from all stations totally were calculated. About the spatial diversity the range of Shannon - Wiener diversity index were between 0 - 0.6674 for annelids, 0.8718 - 1.92 for aquatic insects,0.5404 - 1.917 for crustaceans and 0.3035 - 1.15 for mollusks, while were 1.076 - 2.085 for all the benthic groups totally.The values of Richness index were from 0 - 1.127 for annelids,0.778 - 3.683 for aquatic insects, 0.5212 - 2.104 for crustaceans and 0.2543 - 1.277 for mollusks, while were 2.321 - 5.225 for all the benthic groups totally. The values of Evenness index were ranged between 0 - 0.9629 for annelids,0.4649 - 0.7419 for aquatic insects ,0.3016 - 0.8327 for crustaceans, and were 0.2189 - 0.8974 for mollusks, while were 0.3121 - 0.77 for all benthic groups totally. The values of Dominance index were ranged from 0.6129 - 1 for annelids, 0.343 - 0.7736 for aquatic insects ,0.2991 - 0.8772 for crustaceans,0.5075 - 0.9845 for mollusks while were 0.2638 - 0.7762 for all benthic groups totally.About the temporal diversity the values of Shannon - Wiener diversity index were between 0 - 0.99 for annelids, 0 - 2.01 for aquatic insects, 0 - 1.5 for crustaceans and 0 - 1.637 for mollusks, while were 0 - 1.981 for all benthic groups totally. The values of Richness index were from 0 - 0.969 for annelids, 0 - 2.717 for aquatic insects, 0 - 1.314 for crustaceans and 0 - 731 for mollusks, whilewere 0 - 3.047 for all the benthic groups totally. The values of Evenness index were ranged between 0 - 1 for each of annelids, aquatic insects and crustaceans, and were 0 - 0.992 for mollusks, while were 0 - 971 for all benthic groups totally. The values of Dominance index were ranged from 0 - 1 for each of four benthic groups, while were 0.3 - 1 for all benthic groups totally.Whittaker Beta index between the three different aquatic habitats for each main macrobenthic invertebrate group was calculated. The lowest value 1.14 was recorded for the mollusks between the middle marsh of um Al - Shoowaich and Al - Chebaeish, and highest value 1.66 was recorded for the aquatic insects between the east Hammar marsh and marsh of Al - Chebaeish, while the index values for all groups of macrobenthic invertebrate totally were ranged from 1.33 between the Shatt Al - Arab river and east Hammar marsh to 1.54 between the Shatt Al - Arab river and marsh of Al - Chebaeish.Jaccard Similarity index for each main macrobenthic invertebrate group for each stations was calculated.The values of index for annelids were ranged from( 0 - 89)% the lowest value recorded between Al - Burgah and Al - Sibitia stations and the highest value between Al - Salihia and Multaqaa of Al - Mashab and Al - Sallal stations, for the aquatic insects the values of index between (8.3 - 46.7)% the lowest value between Al - Salihia and Al - Sibitia and the highest value between Al - Mohammediat and Al - Badria stations, for the crustaeceans values ranged(14.3 - 77.8)% the lowest value between Al - Mohammediat and Al - Badria stations while the highest value between Al - Sibitia and Al - Badria,and for mollusks were between(18 - 80)% the lowest value between Al - Mohammediat and Al - Burgah stations while the highest value between Multaqaa of Al - Mashab and Al - Sallal and Abo Sobat stations.The index for all macrobenthic invertebrate groups totally also calculated and its values were from (15 - 58.5)% recorded between Al - Mohammediat with Al - Sibitia stations and between Al - Mohammediat with Al - Salihia stations respectively.Bray - Curtis index was calculated monthly for each main macrobenthic invertebrate group in each stations .Also the Bray - Curtis index was calculated annually between stations and the results refer that the highest values as the following : 0.993 for the annelids between Al - Badria and Al - Sihaqee stations, 1 for the crustaceans between Al - Salihia and Al - Sibitia stations, and 0.96 for the mollusks between Al - Sibitia and Abo Sobat stations.The highest value for all benthic group totally was 0.983 between Al - Salihia and Abo Sobat stations.On other hand Bray - Curtis index was calculated for all macrobenthic invertebrate groups totally between the three aquatic habitats and the values were ranged from 0.5 recorded between the wetlands of um Al - Shoowaich and Al - Chebaeish to 0.875 recorded between the east Hammar marsh and wetlands of um Al - Shoowaich.The Canonical Correspondence Analysis (CCA) by using Canoco application revealed the clear effect of different ecological factors on numbers of the individuals and species of each group of macrobenthic invertebrate in all stations during the study period.

المستخلص: تضمنت الدراسة الحالية جمع نوعين من الاسماك النهرية هي سمكة البلطي الزيليCoptodon zillii والكارب البروسي Carassius auratus من اربعة انهار في قضاء ابي الخصيب وهي نهر( السراجي وحمدان ومحيلة وابو مغيرة )وعلى فترتين ,امتدت الاولى من شهر حزيران 2013 ولغاية شهر تشرين الثاني 2013 وامتدت الثانية من شهر كانون الاول 2013 ولغاية شهر مايس 2014 . اجريت الدراسة الحالية بمحورين شمل المحور الاول دراسة التغيرات النسجية المرضية في اعضاء الغلاصم والكبد والكلية والعضلات وللسمكتين اما المحور الثاني فتضمن دراسة تراكم اربعة من العناصر الثقيلة(الرصاص والنحاس والنيكل والكوبلت) في انسجة الكبد والعضلات وذلك لغرض ايجاد علاقة بين المحورين . قد بينت الدراسة النسجية للاعضاء المدروسة ظهور تغيرات نسجية مرضية اختلفت في شدتها بين نوعي الاسماك اذ تبدو انسجة اسماك الكارب اكثر تضررا من انسجة اسماك البلطي فضلا عن اختلافها بين افراد النوع الواحد , ففي الغلاصم تمثلت التغيرات المرضية بتغير شكل الصفائح الغلصمية الثانوية وفرط تنسج hyperplasia النسيج االظهاري وانفصاله detachment ولوحظ تضخم hypertrophy الخلايا الظهارية وانتفاخها swelling وتضخم وزيادة اعداد خلايا الكلورايد فيها فضلا عن ظهور فرط تنسج الغضروف في الهيكل الساند للخيط الغلصمي الذي رافقه في بعض الاحيان تجمع خلايا بيضوية طرفية النواة في غلاصم اسماك الكارب . في الكبد تمثلت التغيرات المرضية باحتقان congestion اشباه االجيوب الكبدية وتليفات fibrosis في نسيج الكبد وتنكس degeneration وتنخرnecrosis الخلايا الكبدية وتغيرات نووية تمثلت بانحلال النواة وتكتل مادتها الكروماتينية karyopiknosis ولوحظ وجود ودمات oedema وتراكم مواد غير حية بنية ووردية اللون داخل وخارج الخلايا الكبدية . اما في الكلية فقد شملت التغيرات المرضية النسجية جميع مكوناتها اذ تمثلت بتنكس الخلايا الظهارية للنبيبات الكلوية وانتفاخ بعض منها مما يؤدي الى ضيق تجويف النبيب ولوحظ حدوث انسلاخ بطانة بعض النبيبات الكلوية , وظهر فرط تنسج النبيبات الكلوية في كلية اسماك البلطي فقط بشكل كتل كبيرة بيضوية الشكل , ولوحظ وجود مواد غير حية في النسيج المكون للدم يحاط البعض منها بمحفظة ليفية من عدة طبقات في سمكة الكارب ,اما في الكبيبات فقد لوحظ احتقان وتوسع aneurism اوعيتها الدموية, وشوهد ضمورatrophy بعض الكبيبات وتضخم بعضها الاخر مما يؤدي الى توسع او تضيق حيز محفظة بومان. تمثلت التغيرات المرضية النسجية في الامعاء بتنكس خلايا النسيج الظهاري وتنخر قمم الزغابات ولوحظ ان التنكس والتنخر يصل في بعض العينات الى النسيج الضام للصفيحة الاصيلة وشوهد ارتشاح infiltration الخلايا البدينة mast cells باعداد كبيرة في الطبقة تحت المخاطية لامعاء اسماك البلطي وارتشاح انواع اخرى من الخلايا الالتهابية في اسماك كلا النوعين , وكثيرا ما شوهد تاثر الخلايا العضلية في طبقة العضلات لجدار الامعاء. اما انسجة العضلات فقد شهدت ظهور العديد من التغيرات تمثلت بتنكس اسفنجي spongy degeneration يتبعه تنخر الخلايا العضلية وكثيرا ما شوهد تعرج الليفات العضلية وانعدام التخطيط العرضي . قد تعزى هذه التغيرات الى تلوث مياه الانهار المدروسة بمختلف الملوثات ومنها المعادن الثقيلة وذلك من خلال قياس التراكم الحيوي لهذه العناصر في عضلات واكباد هذه الاسماك واكد وجود هذه العناصر تقنية الكيمياء النسجية اذ لوحظ ان المعادن المتراكمة في النسيج تعطي انعكاسات لونية مختلفة بحسب نوع العنصر الثقيل ,و لوحظ عند قياس التراكم الحيوي ان معدلات تراكم بعض هذه العناصر(الرصاص والكوبلت) في انسجة العضلات يفوق الحدود المسموح بها عالميا . اختلف تراكم هذه العناصر من عضو الى اخر ومن نوع الى اخر ومن فترة الى اخرى ,فقد وجد ان معدلات تراكم عناصر الرصاص والنيكل والكوبلت في العضلات كان اعلى من معدله في الكبد وبفرق معنوي عند مستوى احتمالية p<0.05 في حين اظهر النحاس نتيجة معاكسة اذ كان معدل تراكمه في الكبد اعلى من العضلات وبفرق معنوي عند مستوى احتمالية p<0.05 , اما بالنسبة لفترتي الدراسة فقد سجلت الفترة الاولى في كبد سمكة البلطي معدلات تركيز اعلى من الفترة الثانية لكل من عناصر النحاس والنيكل والكوبلت وبفرق معنوي عند مستوى احتمالية p<0.05 . اما في مياه الانهار المدروسة فقد كان اعلى تركيز بلغه عنصر الرصاص 602 مايكروغرام\لتر واقل تركيز له 141 مايكروغرام\لتر,واعلى تركيزلعنصر النحاس كان 77 مايكروغرام\لتر واقل تركيز 25 مايكروغرام\لتر, واعلى تركيز لعنصر النيكل كان 392مايكروغرام\لتر واقل تركيز له214 مايكروغرام\لتر,واعلى تركيز لعنصر الكوبلت كان 173مايكروغرام\لتر واقل تركيز72مايكروغرام\لتر | The current study includes collection of two species of fish. a tilapia fish (Coptodon zillii) and Prussian carp ( Carassius auratus) from four rivers in Abu Alkhaseeb region which are Sarraji, Hamdan, Mhella and Abu Mugherra River at two periods, the first period starts from June 2013 till November 2013 and the second period from December 2013 to the end of May 2014. After bringing the fish to the lab dissecting to rescet excised organs of the gills, livers, kidneys , intestines and muscles. the current study have been performed on two axis .The first axis includes the study of histopathological changes in the organs above for two species The second axis guarantees the study of the bioaccumulation of four heavy metals (lead ,copper, nickel ,cobalt) in the tissues of the liver and muscles for the purpose of finding a relationship between the two axes. The histological observations showed histopathological changes different in severity between the two specis of fish , the tissue of C.auratus seems to more be affected than the tissue of C.zillii , In the gills, the pathological changes are represented in the shape changes of secondary lamella of gills , hyperplasia and detachment of epithelial tissue . Hypertrophy and swelling in epithelial cells , hypertrophy and increase the number of chloride cells where noted . Hyperplasia cartilage in Bracket structure of gills thread which coincide with some gathering terminal oval cell nucleus often in gill, carp was seen. In the liver has represented pathological changes like congestion of liver sinusoid , fibrosis in liver tissue , degeneration and necrosis of hepatocytes and the nuclear changes represented in the dissolution of the nucleus and conglomerate chromatin material ( karyopiknosis), the appearance of some oedema and accumulation of non - living material inside and outside the hypatocytes . In kidney ,the histopathological changes included represente by epithelial cells degeneration of the renal tubules and swelling some of them leading to a narrow tubules cavity, also observed shedding the epithelial layer lining of some renal tubule, while in the glomeruli, congestion and aneurism its veins atrophy of some glomeruli was obsererved and that leads to expansion or narrowing Bomans space . In addition non - living materials in the component tissue of blood were observed, some of which are surrounded by a fibrous capsule of several layers in C.auratus kidney only. Some of non - liver materials in the cytoplasm of some of renal tubule cells were seen, while, intestinal histopathological changes were represented by degeneration of epithelial cells and necrosis of villi peaks and it was observed that the degeneration and necrosis reach in some samples to the connective tissue and often spotted muscle cells affected in the muscle layer of the intestinal wall. Also it is observedin a large numbers of mast cells infiltration in the submucosa layer of the gut C.zillii and infiltration other types of inflammatory cells in both fish species, while muscle tissue were less affected than the other organs. There were several changes represented by spongy degeneration followed by necrosis of muscle cells , and often were seen in the limping of muscle fibers and the lack of cross - planning in this muscle. These histological changes were due to water pollution of rivers under studing by various pollutants such as heavy metals that were included in thestudy and that by measuring the bioaccumulation of heavy metals in the tissues of the muscles and liver of these fish and was assured that by Histochemistry technique as it was observed that the accumulated metals in the tissues give different reflections of color by heavy element type. It was observed that when measuring bioaccumulation , the accumulation rates of some of these elements (lead and cobalt) exceeds the permitted globally border. It was observed that the accumulation of these elements vary from one organ to another and from one specis to another and from one period to another, it was found that the rates of accumulation of elements ;lead , nickel and cobalt in the muscle were higher than that in the liver and at significant difference of 0.05 level of probability, while copper showed the opposite conclusion, as its rate of accumulation in the liver was higher thane at significant differenc of 0.05 level of probability. Regarding the two periods of the study, the first period recorded higher concentration in the liver of C.zillii than the second period for copper ,Nickel and cobalt elements at significant 0.05 difference are level of probability. . The rates of concentration of heavy elements that included in the study of the water of the rivers were nearly the same to former studies, as the highest concentration recorded for lead was 602 micrograms \ liter and the less concentration was 141 micrograms \ L, while the highest concentration of copper was 77 micrograms \ liter and less concentration was 25 micrograms \ L. The highest concentration of the nickel was 392 micrograms \ liter and its less concentration was 214 micrograms him \ l. The finally highest concentration of cobalt was 173 micrograms \ liter and its less concentration was 72 micrograms \ L

المستخلص: This study dealt with the genetic polymorphism of Phenylthiocarbamide (PTC) tasting from phenotypic and genotypic (Molecular of TAS2R38(P49A) gene ) prospective,among sample of Basrah Population from 2014 - 2012. Also, a comparative Molecular study for the gene TAS2R38(P49A) and some biochemical parameters was made in a group of Diabetic patients for the first time in Iraq /Basrah and the world .Phenotypic study using the gradient dilutions of PTC substance method, was established among 317 individual : 96Males and 221 Females from different regions of Basrah. Increased sensitivity with low threshold 6 of Males than Females 5 was observed which indicate that the Males were more sensitive than Females in this region from Iraq .However, the tasters percent among Females still higher73.3% than Males72.9% ,and the whole population 73.2% as well .This study recorded different tasters percent in different regions : 62.1%,71.8% ,60.6%, 82.3% for the North ,AL - Zubair and Safwan, Abu - ALChaseab and AL - Fao and the center of the city respectively, although ,the whole population of Basrah found to be under Hardy - Weinberg Equilibrium . Allelic frequencies according to phenotypic analysis showed : recessive allele t had higher frequency (0.53) than dominant allele T (0.47), with elevated Heterozygous frequency Tt among all studied regions and the whole population(0.53) .The results recorded also , high BMI for non tasters tt as a whole and for both sexes in this phenotype : 28.32 ,28.26 for males and females respectively. While it had the lowest value among heterozygous 23.40 ,Statistical analysis for phenotypic study of this locus reveald an additive effect of the two alleles T,t by 81.33% with responsibility of 83.10% for the phenotypic variation found in this trait . Genetic (Molecular) analysis was done for comparative individuals and diabetic patients by sequencing the hTAS2R38(P49A) the PTC gene, among 127 individual : 59 healthy individual as a comparative group and 68 diabetic patients from both sexes and same age ranges. The results recorded a C/G allele in the position of the first SNP (145 C/G) which encode for Proline amino acid (C) or Alanine amino acid (G) : CC , CG refer to Tasters genotypes while GG refer to Non - tasters genotype. High frequency of C allele as compare to G among both healthy people and diabetic patients : 0.55, 0.53 for both respectively . Frequency of heterozygous genotype CG recorded a significant access as 0.76 among the comparative group which may implies a selective heterozygosity advantage among Iraqi population at this region. A significant differences in genotypic distributions was recorded between comparative and diabetic groups with high incidence of non tasters phenotypically tt 41% and genotypically GG 20.5 % among diabetic patients compare to healthy people : 25 % , 7% respectively . Interestingly non taster GG genotype had the lowest BMI among diabetic patients compare to othertwo taster genotypes CC, CG respectively. . Study of Genotype - Phenotype Association revealed significant correlation (p<0.0001) between them among comparative group as 86.9% and diabetic group as 48.8%. A comparative study of Biochemical analysis betweendiabetic and non diabetic individuals from different genotypes for TAS2R38 (P49A) gene showed significant elevated value of cholesterol among diabetic from the GG genotype 191.85 ± 6.57 mg/dl with non significant elevated values of Hb1c 8.93 ±1.77 and triglyceride 149.57±6.53 mg/dl. However, all these parameters were significantly more higher among diabetic than non diabetic . Significant differences(P<0.05) were recorded between diabetic and non diabetic according to their thyroid hormones levels with low values of T3 , T4 and high values of TSH among diabetic than non - diabetic. TSH hormone recorded its highest significant values among diabetic of CC genotype with 4.39 ± 0.16 μUI/ml as compare to the other two genotypes heterozygous CG and recessive homozygous GG . Although non significant , T4 recorded its lowest values among diabetic of the CC genotype .However, significantly (P <0.05 ),T3 hormone found to have lower values in the two homozygous genotypes; CC genotype for diabetic 0.54± 0.03 ng/ml and non diabetic 0.53±1.64 ng/ml ; GG genotype : 0.72± 0.04 ng/ml ; 1.82± 0.59 ng/ml for diabetic and non diabetic respectively . while individuals with CG genotype found to be non significantly different .Lastly it could be concluded that this trait may have some effect on BMI and may play a role the variation found among peoples in biochemical parameters (cholesterol, thyroid hormones ) changing's especially among diabetic patients.

المستخلص: Aim of study was to evaluated the effects of propylthiouracil (Ptu) drug on both maternal and fetus rats, used experimental animals (Rattus norvegicus) and after housing, breeding and adapting, (50) of virgin females choosen, isolated and then divided into two groups each group contain (25)rats, The mean weight of the animals was(200 ±50) gm and (8 - 10) week of age. Females on first group regarded as control and treated with distilled water while animals in second group were treated with (Ptu)dose as (0.05 %) and left for(14.5, 16.5, 18.5, 20.5, 21.5)for each group. Macroscopic observations on each group were recorded including changes in thyroid gland morphology, hypertrophy and enlargement at each period (14.5, 16.5, 18.5, 20.5, 21.5) days of gestation for both pregnant rats and embryos,the shape of uterine hornes,and uterus with changes of fetus number, resorption, atrophy, malformation of body parts, indifferentiation of fore and hind limbs, skin abnormalities were noticed. The changes in placenta which appeared irregular, pale colour, congested with white fibrous regions were noticed in hypothyroid rat comparing with placenta of control group animal, which looked red, discoid shape and normal surface without any abnormal signs, in addition fatty ovaries with large amount of adipose tissue was accumulated in abdomen cavity, the ovaries irregular and showed structures in most pregnant rats of hypothyroid group comparing with control pregnant females.Present showed significant decreased at (P≤0.05) in mean length, weight and number of fetus at (14.5, 16.5, 18.5, 20.5, 21.5) days of gestation in all embryos related to hypothyroid rats compared to control. Histological study with light microscopy on sections from thyroid gland related to rats with induced hypothyroid showed reduced, small follicles with empty or little colloid substance, each follicle lining simple cuboidal or flat epithelium, an increased with stroma, variable size of follicles most of them smaller compared to control thyroid gland from control rats, which showed normal lobules, large follicles filled with colloid, and poorly stroma.Sections from uterus, ovaries, oviduct related to hypothyroid rats showed variable histological changes ranged from mild to severe like abnormal reduced layers of uterus, irregular uteri folded, degenerated with simple epithelial tissue that lining the uterus villi, haemorrhage in uterine gland, deposition of collagenous fibers, infiltration of lymphocytes and accumulation of adipose tissue. Ovaries from hypothyroid rats showed variable changes with ovaries follicles maturation, accumulated of adipose tissue, decreased graffian follicles, infiltration of lymphocytes and deposition of collagenous fibres with degenerated of lining epithelial layer compared with control ovaries.Microscopic observations of placenta sections from hypothyroid rats at different period of gestation revealed loss tissue, reduced placental layers thickness, necrosis in the peripheral regions, degenerated cytotrophoblasts that surrounding capillaries, the trophoblast giant cells appeared with degenerative changes in labyrinth and spongiotrophoblasts regions. undifferentiated fetal blood capillaries compared to control which the sections have normal structure differentiated to decidual basalis and labyrinth zones, the junctional zone composed of outer giant cells that separated the decidua basalis and trophospongium.In this study the ultrastructural changes in thyroid gland from maternal and fetus related to hypothyroid rat at (14.5, 16.5, 18.5, 20.5, 21.5) days of gestation were identified by electron microscopy and included changes in apical cytoplasm of follicular cells to microvilli, blebs and protrusions also dilated rough endoplasmic reticulum, increased lysosomes, the empty vacuoles more than the dense vesicles, increased mitochondria and Golgi apparatus cisternae, changes chromatin and more cellular debris. Biochemical results in thyroid hormones revealed to significant increase in mean concentration of (TSH) in pregnant females with hypothyroidism during gestation periods in compared with control group, also there was an decrease in both (T3, T4) non significant, significant increased concentration in serum of pregnant rats on treated group with (Ptu) compared with their concentration of control pregnant rats.Levels of some oxidative enzymes (GSH & MDA) was estimated in this study and there was significant increased,non significant in their concentrations in serums of rats with induced hypothyroidism comparid to control group during each period of gestation (14.5, 16.5, 18.5, 20.5, 21.5) day. The study determined some of haematological parameters such as (R.B.Cs) count, (H.b) level and (P.C.V) ratio which showed non significant at (P≤0.05) hypothyroidism rats compared with control rats at the same period of gestation. Also the results revealed non significant with (T.L.C), (D.L.C) in all pregnant rats with hypothyroidism compared to control rats, the data showed an increased with lymphocytes and Neutrophils and Esoinphils cells in smears prepared from hypothyroidism rats compared to control group

المستخلص: The present study was conducted to evaluate the effect of different concentrations of the growth regulators 2, 4 - D; Dicamba and NAA on the induction of date palm (Phoenix dactylifera L.) primary callus Hillawii cv., by analyzing morphological, biochemical; anatomical and molecular responses. Three concentration of 2, 4 - D (10; 50 and 100 mg/L), Dicamba (1; 5 and 10 mg/L) and 30 mg/L of NAA were examined during the course of this study. in addition, several antimicrobial agents were selected to evaluate their morphological and biochemical impacts on the primary callus of date palm including the antibiotics (Gentamycin 50 mg/L and Chloramphenicol 50 and 100 mg/L), as well as, the fungicides (Switch 1 g/L and Beltanol 1 ml/L), After induction of the primary callus from each treatments, the following results were obtained : 1. The results showed that the treatments with 2, 4 - D at 10 mg/L and Dicamba at 1 and 5 mg/L did not stimulate any callus growth over the time of incubation on MS medium.2. It was evident that the treatments of different growth regulators have a significant effect on the initial period (day) for callus initiation, the shortest period have been obtained with the low concentration of 2, 4 - D (50 mg/L) and Dicamba (10 mg/L) which were 67.57 and 66.75 days, respectively, while the high concentration of 2, 4 - D (100 mg/L) led to increase this period significantly up to 120 days.3. Both fresh and dry weight of date palm primary callus decreased significantly at the treatment of high concentration of 2, 4 - D (100 mg/L) up to two folds compared to the treatment at low concentration of 2, 4 - D (50 mg/L), similar trend of results were found with browning percentage and intensity.4. Biochemical analysis of produced date palm primary callus revealed that the high concentration of 2, 4 - D (100 mg/L) led to a significant increase in the total content of carbohydrates; Proline, Peroxidase activity and Phenolic compounds which considered as a stress indicators, and another decrease of total soluble proteins and free amino acids was accompanied with this treatment compared to the same growth regulator at low concentration and Dicamba treatments.5. Anatomical study revealed that asignificant damage was caused by the high concentration of 2, 4 - D (100 mg/L) on date palm primary callus, this damage was evident from the abundant and distribution of tannins compounds across the primary callus tissues, thus, was accompanied with high percent of browning, compared with the treatments of 2, 4 - D at low concentration, Dicamba and NAA.6. The analysis of Protein profile revealed the similarity between the patterns of control treatment (juvenile leaf of Hillawii cv.) and 2, 4 - D at low concentration, as well as, Dicamba. Similarity indices results for protein profile of date palm primary callus proved the genetic similarity of 100% between control treatment and both 2, 4 - D (50 mg/L) and Dicamba ones, while, the lowest similarity percentage was observed with high concentration of 2, 4 - D (100 mg/L).7. The results of RAPD marker analysis of the extracted genomic DNA form date palm primary callus using four deca oligonucleotide primers showed the efficiency of three primers (OPAR3; OPAR8 and P.650) in their amplification of examined DNA,. RAPD profile revealed an identical matching between control treatment and 2, 4 - D at low concentration, followed by Dicamba and NAA auxins, while, the increasing in 2, 4 - D concentration up to 100 mg/L led to disappearance and the appearance of new DNA bands compared to control treatment, with a highest genetic distance among other treatments.Similarity coefficient analysis showed that the highest genetic similarities were found between control treatment and 2, 4 - D (50 mg/L) with similarity index of 96% , followed by Dicamba and NAA treatments with indices of 74 and 66%, respectively, the lowest similarity index was obtained between control and 2, 4 - D at high concentration which was 27%.8. The screening results of antimicrobial agents showed that the treatment with Switch fungicide (1 g/L) and Gentamycin antibiotic ( 50 mg/L) did not stimulate any callus growth over the time of incubation on MS medium supplemented with either 2, 4 - D or Dicamba.9. Beltanol fungicides (1 ml/L) treatment had a negative effect on the initiated primary callus either by 2, 4 - D or Dicamba, its treatment led to a high significant reduction in total solubleprotein and free amino acid content compared to control results, while an increase of total carbohydrates, Phenolic compounds, Proline and Peroxidase activity was detected with Beltanol fungicide.10. The Chloramphenicol treatment at low concentration (50 mg/L) showed positive results on the growth of primary callus at 2, 4 - D or Dicamba auxins according to morphological and biochemical analysis.

Their growth rates and biodegradation ability were investigated in mineral salt media supplemented with light Remella crude oil. These strains consist of Streptomyces variabilis 7525, Streptomyces variabilis 5W75, Streptomyces cellulosae XFB - T, Streptomyces parvus S86, Streptomyces bacillaris S4BW2, Streptomyces flavoviridis VITHM - 1 and Nocardiopsis synnemataformans ITD - 3, that the sequence identity range from 99% to 100%. Our study find a new actinomycetes strains isolated from contaminated soil. these strains appears different capacity on the degradation of crude oil in mineral salt media , the highest was found to vary from 50.2% to 72.4%.The effect of the cultivation factors (temperature, pH, and concentration of crude oil and trace elements ) on growth of the actinomycetes strains and crude oil degradation was evaluated. The highest cell growth and the amount of crude oil degraded 80% were observed in optimized cultivation conditions (30oC and initial pH 7) after 10 days, this ratio reached to 85% by addition of trace elements solution at same condition by S. cellulosae XFB - T.The biodegradation test lasted 60 days in soil by actinomycetes strains at different factors shown the highest of the crude oil was removed in experiment that inoculums with 10ml of each bacterial strain, value 87% by Streptomyces bacillaris S4BW2 at 30oC. Bioremediation is an efficient strategy for cleaning up sites contaminated by hydrocarbons. Microorganism of soil is affected by hydrocarbon disturbance thus selective enrichment of hydrocarbon utilizers occurs. The technology is very effective in dealing with petroleum hydrocarbon contamination. Hydrocarbons react with the soil matrix and microorganisms determining the fate of the contaminants relative to their chemical nature and microbial degradative capabilities. The potential effects of sawdust, and mixture of cow and sheep dung as amendment nutrient supplements to biostimulate autochthonous microflora and augmentation for hydrocarbon bioremediation were investigated in test biopile and bioreactor. The soil was ground and fluffed by admixture of 1.5% sawdust, then supplemented with the necessary minerals and watered to provide conditions favoring microorganism growth industrial aeration was provided in pile by system of a abundant perforated drainage - pip network to simulate bioremediation treatments through a 90 - day period. During this period, we monitored total petroleum hydrocarbons (TPHs) and n - alkanes degradation and changes in bacterial communities. The (TPHs) had been reduced from 52 to 10.6 g/kg (79.6 %), the rate of Biostimulants Efficiency (BE) was (71.4%) in biopile and from 52 to 13.5 g/kg (63.5 %) in bioreactor . In soil, the dominant microorganism population comprised Gram - positive bacteria from actinomycete group and autochthonous microorganisms which decompose hydrocarbons reached highest level 2 x 107 and to 1.1 x 107 CFU/g at 45 days in biopile and bioreactor respectively . Based on these data, the study conclude that is ex situ ( Biopile and bioreactor ) experiment the best strategy, inexpensive, efficient, and environmentally friendly and may thus offer a viable choice for petroleum hydrocarbons - contaminated soil remediation.

The first adjoint pair of covariant functors consists of the forgetful functor from the category of profinite crossed modules to the category of profinite transformation groups and the left adjoint functor from the category of profinite transformation groups to the category of profinite crossed modules, where the later one explains how to construct a profinite crossed module from a profinite transformation group. The second adjoint pair of covariant functors consists of the forgetful functor from the category of free profinite crossed modules to the category of continuous maps (from profinite spaces into profinite groups) and the left adjoint functor from the category of continuous maps to the category of free profinite crossed modules, where the later one explains how to construct a free profinite crossed module on a continuous map from a profinite space into a profinite group. Finally, we study the coproduct in the category of profinite crossed modules.

المستخلص: In this study, two types of Schiff base were prepared as ligands L1, L2, by reaction of an equal number of moles of tris(hydroxymethyl) methyl amine with salysildehyde and vanillin in a methanolL1 : ((E) - 2 - ((2 - hydroxybenzylidene) amino) - 2 - (hydroxymethyl) propane - 1,3 - diol) L2 : ((E) - 2 - ((4 - hydroxy - 3 - methoxybenzylidene) amino) - 2 - (hydroxymethyl) propane - 1,3 - diol).The Cu(II) and Mo(VI) complexes were prepared to produce the : - A1 : tetrakis(μ3 - 2 - {[1,1 - bis(hydroxymethyl) - 2 - oxidoethyl] iminomethyl} - phenolato) tetrakis [aqua copper(II)].A2 : tetrakis(μ3 - 2 - {[1,1 - bis(hydroxymethyl) - 2 - oxidoethyl] iminomethyl} - 2 - meth - oxy} - phenolato) tetrakis [aqua copper(II)].B1 : (E) - 2 - methyl - 2 - ((2 - ((methyl(l1 - oxidanyl) dioxomolybdenio) oxy) benzylidene) amino) propane - 1,3 - diol).B2 : (E) - 2 - ((4 - hydroxy - 3 - ((methyl(l1 - oxidanyl) dioxomolybdenio) (methylene) - l4 - oxidanyl) benzylidene) amino) - 2 - methyl) propane - 1,3 - diol).The ligands and complexes were characterized by Fouries transformer infrared FTIR, UV and NMR techniques.All these techniques insisted that the ligands and their complexes were prepared successfully.On the other hand, the four complexes A1, B1, A2 and B2 were evaluated as corrosion inhibitors against a corrosive environment of 0.1M of hydrochloric acid at constant temperature of 25°C and different concentration for each one of the above complexesIIrange (10 - 50) ppm and it has been found that the efficiency of inhibition at a temperature 25℃ are not highly efficient, the KI was added in order to increase the efficiency of these inhibitors values to these inhibitors.The inhibition efficiency for all inhibitors was increased in presence of KI compared with the absence of it.On the other hand, the complexes of copper i.e., A1 and A2 have higher efficiency than molybdenum complexes i.e. (B1 and B2) this can be attributed to the ability of copper ion (II) to donate the electron density to the ligand by back donation competence these behaviour compared with molybdenum ion (VI) that has not the ability that present in copper ion, Also studied the effect of concentration of the inhibitor prepared in other temperatures change separately and these grades are within the range (35 - 55) ℃ has been observed that efficiency does not increase either the existence of KI with the inhibitor, or without, but the decreasing efficiency with increasing temperature, means that the inhibitor adsorbed physically on carbon steel alloy.The functions thermodynamic adsorption such as free energy, enthalpy and entropy were studies depending on the adsorbent layer θ on the surface of the carbon steel alloy. The data was shown all the complexes are subject to model for Langmuir adsorption was shows the free energy negative values means that the interaction is spontaneous and notes total increasing of the temperature less than the negative value of the free energy leading to towards the is non - spontaneous. The negative values of enthalpy means that the interaction is exothermic, the negative value of the entropy of adsorption ΔSads and gradually moving toward positive values with a high temperature means that the random was less in high temperature. Also the kinetics of corrosion in the absence and present of the inhibitor was studied with KI in (0.1) M HCl. The activation energy and other thermodynamic function such as enthalpy and entropy and free energy was shown that the higher activation energy in presence inhibitor and it was higher in presence of KI with inhibitor. This is an indication that the interaction of corrosion is small in the presence of these inhibitors.

As measured for inhibitors thermal stability TGA&DTA has been found to be inhibitors stable thermally It was found that the inhibitor (Bis(2 - ((2 - hydroxyethyl) thio) ethyl) terephthalate stable up to a temperature (240) ˚C and the inhibitor Bis(2 - ((6 - Mono malic acid - hydroxyl ethyl ester) sulfanyl) ethyl terephthalate stable up to a temperature (230) ˚C This is evidence of its effectiveness within these thermal grades of industrial processes, particularly their work inhibitors corrosion.The two inhibitors were evaluated as corrosion inhibitors using hydrochloric acid as corrosion media for carbon steel alloy( carbon steel C1010) . The factors effect on the rate of corrosion like temperature , concentration of inhibitor were studied by the electrochemical technique using the Tafel plot.The obtained results at temperatures range ( 298 - 328) K and concentrations (10 - 50) ppm were used to calculate many factors that determined the efficiency of the inhibitor like : corrosion rate , corrosion current , charge transfer resistance , Anodic Tafel constant , Cathodic Tafel constant , corrosion potential and inhibitor efficiency. It was observed that the corrosion rate increases with increase of temperature and decreases with increase of the inhibitor concentration in the same temperature. The Results showed that both inhibitors had very high inhibition in reducing the corrosion rate .The inhibition efficiency reached (97.1%) for (Bis(2 - ((2 - hydroxyethyl) thio) ethyl) terephthalate for the 40 ppm at (308) k and (96.2%) for the Bis(2 - ((6 - Mono malic acid - hydroxyl ethyl ester) sulfonyl) ethyl terephthalate for the 50 ppm at (298) k.Many thermodynamics functions was calculated ,activation energy Ea , activation entropy ΔS* , activation enthalpy ΔH* and free energy ΔGads during the different experiment conditions, which was indicated of the corrosion inhibition efficiency and the type of the inhibition. The obtained results showed that the two inhibitors were very efficient to reduce the corrosion rate in the acidic media and from the ΔGads data the type of adsorption was physisorption and chemisorption. because the value of ΔGads was higher than ( - 20 KJ/mol) and less than ( - 40 KJ/mol).
