Two mixed ligands were chosen : sulfamethoxazole and 4,4/ - dimethyl - 2,2/ - bipyridyl (L2). This is done to prepare another series of complexes with some metal ions ( Co(II), Ni(II), Cu(II), Cd(II), Cr(III) , V(IV), Pd(II) and Au(III)) in order to investigate the coordination behavior of these ligands(L1) and (L2) toward these metal ions.These complexes, already prepared by the solid state, were characterized by the elemental analysis (C.H.N.S) and FT - IR , UV - Vis spectroscopy, in addition to the flame atomic absorption, magnetic susceptibility , melting point and conductivity measurements. According to the results obtained, it is noticed that ligand L1, with the light and heavy metal ions, clearly behaves as a bidentate through the O atom of sulfonyl group and N atom of sulfonylamid group for all the prepared complexes except Cu(II) and Ni(II). In this case, the ligand confirms that the bonding of the metal ion in a tridentate chelate through the O atom of sulfonyl group and N atom of sulfonylamid group and N atom of amine group.While L2 behaves as a bidentate ligand through two N atom. Conductivity measurements have shown that all the prepared complexes are ionic except PdL1L2 complex. Based on the results of the measurements, the following formula have been suggested for the new prepared complexes : - [VOL1L2]SO4.2H2O and [CuL1L2]2( NO3)4.0.5H2O have square pyramidal geometry while the following complexes are having octahedral geometry : - [CrL1L2 Cl2] Cl.H2O,[NiL1L2NO3]2 ( NO3)2.0.5 H2O,[PdL1L2 Cl2].0.5H2O,[PtL1Cl3H2O]Cl.H2O, [Au L1L2Cl2] Cl.2H2Oand the complexes below have tetrahedral geometry : - [CoL1L2] (NO3)2.3H2O,[CdL1L2](NO3)2.3H20 while [PdL1Cl]2 Cl2.H2O,[AuL1Cl2]Cl.3.5H2O,[RhL1ClH2O]Cl2.0.5H2O have square planar geometry.Different bonding and structural behaviors were revealed throughout the study of coordination chemistry of the newly prepared metal complexes.The nature of bonding between the metal ion and the donor atoms of the ligands were demonstrated by calculating Racah parameter and the other ligand field parameters which were calculated using suitable Tanaba - Sugano diagrams.The nature of the complexes in ethanol solution was studied for some of the prepared complexes such as (RhL1,PdL1,PtL1 and AuL1) in the solution state to determine the ratio between ligand to metal state by using the molar ratio method which gave results which approximately identical results when compared to those obtained from the isolated solid state. Besides the stability constant of the prepared complexes were studied and it was found that they were stable in molar ratio 1 : 1.

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

Two of benzothiazole derivatives ligands 2 - benzamid benzothiazole (L1) and 2 - acetamid benzothiazole (L2) were used to synthesize two types of transition metal complexes ; Rh(III), Pd(II), Cd(II), Pt(IV) and Au(III) , the other set of complexes was prepared in presence of a co - ligand 1,10 - phenanthroline(L') or 4,4? - dimethyl - 2,2? - bipyridyl (L") with the metal ions V(IV), Cr(III), Co(II), Ni(II), Cu(II), Zn(II) and Au(III) using microwave and conventional methods to compare the results between them. These ligands and their metal complexes were isolated and characterized in solid state using FT - IR, UV - Vis spectroscopy, flame atomic absorption, elemental analysis C.H.N.S. and magnetic susceptibility measurements as well as melting point and conductivity measurements. According to the results of the above measurements, the following shapes were suggested for the prepared complexes : Complexes of ligand (L1) : Complexes of Rh(III), Pd(II) and Au(III) have a square planar geometry, while Cd(II) complex has a Td geometry and Pt(IV) complex has an Oh geometry.Complexes of mixed ligands (L2 with L'/ L") : All complexes have an Oh geometry except V(IV) complex has a square pyramid and Co(II) complex has a Td geometry. The nature of bonding between the metal ion and the donor atoms of the ligands was demonstrated through the calculation of Racah parameter and other ligand field parameters, which were calculated using suitable Tanabe - Sugano diagrams.The nature of some (L1) complexes in liquid state was studied by following the molar ratio method which gave results approximately identical compared with those obtained from the isolated in the solid state; also, stability constants of the prepared complexes were studied , they were stable in the molar ratio 1 : 1. A theoretical treatment of the ligands and the prepared complexes in gas phase was done using two programs; Hyperchem - 8 and Gaussian program (GaussView Currently Available Versions (5.0.9) along with Gaussian 09 which is the latest in the Gaussian series of programs).Hyper chem. - 8 program used the molecular mechanics and semi - empirical calculation, the heat of formation (?H?f), binding energy (?Eb) dipole moment (µ) for the free ligands and their metal complexes were calculated using ZINDO/1, PM3 and AMBER methods at 298 K. It was found that the complexes were more stable than their ligands; furthermore, the electrostatic potential of free ligands was calculated to investigate the reactive site of the molecules, PM3 was used to evaluate the vibrational spectra of free ligands ,the obtained frequencies agreed well with those values experimentally found; in addition, the calculation helped to assign unambiguously the most diagnostic bands. Electronic spectra measurements for the ligands were calculated theoretically using ZINDO/S method comparing it with the experimental results. It was found that there was a closely relationship between the theory and experimental spectra.Gaussian program semi - empirical (PM3) method which used in order to calculate : the geometry optimization, dipole moment (?),total energy ,electrostatic potential, ELUMO and EHOMO was obtained, evaluate the vibrational spectra of free ligands and these obtained frequencies agreed well with those values experimentally found.Also electronic spectra measurements for the ligands were calculated theoretically by using the job type : Single point energy (SP) along with ZINDO method and also the job type frequency (Freq) used along with CIS method (3 - 21G).

المستخلص: The purpose of this thesis is to report quantum chemical investigations into a series of problems related to contemporary organometallic chemistry. In recent years density functional approaches have become the most commonly used theoretical methodology in organometallic chemistry. Alongside these developments, a number of new tools for analyzing electronic structure such as topological analysis of electron density (Atoms in Molecules theory) have emerged. As a result, theory is now in a position to compute ab initio many of the experimental observables that underpin modern organometallic chemistry.The bonding in the Triosmium carbonyl cluster 1 [Os3(? - H)(? - ?2 - dpa - N,N)(CO)10] and Triosmium carbonyl cluster 2 [Os3( ? - H)2(NHC)(CO)9] are explored using the Quantum Theory of Atoms - in - Molecules (QTAIM). The metal - metal and metal - ligand bond critical points properties ?(r), ?2?(r), H(r), G(r), V(r) and ellipticity, and also the bond delocalization indices ?(A, B), are correlated with the data from previous studies of the organometallic systems. These results have allowed a comparison between topological properties of different atom - atom interactions. In the core of dihydride triosmium cluster 2, Os3H2 part, the topological data recognizes the existence of a bond path in the dihydride bridged Os atoms, Os(1) - Os(3) edges, whereas in monohydride triosmium cluster 1 there is no direct bond path has been found for the interaction between the hydride bridged Os atoms, although a non - negligible delocalization index ?(Os(1)...Os(2)) has been obtained for this non - bonding interaction. A multicenter 4c - 4e interaction is proposed to exist in the core part, Os3H, in cluster 1 and bridged part, Os(1) - H(1) - Os(3) - (H2) in cluster 2. In addition, an interaction of 5c - 5e type is proposed to exist in the core part, Os3H2. All topological parameters calculated for the Os - N and Os - C bonds between the osmium atoms and the pyridyl and NHC ligands in compound 1 and 2, respectively, are similar, and they confirm that these interactions are pure ? bond. The analysis of the topological parameters of the NHC and pyridyl ligands bonds confirm the existence of ? - electron delocalization within the six - membered ring of pyridyl ligand and hindered ? - electron delocalization within the five - membered ring of NHC ligand with some double - bond character in the interaction of the carbine C atom with the adjacent N atoms.

المستخلص: تمثل الستيرويدات فئة هامة من العقاقير الطبيعية وكذلك الصناعية نظرا لقدرتها على اختراق الخلايا واداء بعض الوظائف البيولوجية الاساسية وبشكل رئيسي هي عوامل مضادة للفيروسات ومضادات للاورام. وتقسم الرسالة الحالية على ثلاثة فصول.يمثل الفصل الاول مقدمة عامة حو | Steroids represent an important class of natural as well as synthetic drugs because of their ability to penetrate cells and perform some of the most fundamental biological functions mainly as antitumor and antiviral agents. The present thesis is devided into three chapters.The first chapter represented a general introduction concerning the structures of some potent steroids, and the pathways of the synthetic adrenal steroids as well as their pharmacological importance in medicine, in general. This part is focused mainly also on the pregnenolone as an important potentially active steroid, including its structural modification at the hydroxyl and keto groups at C - 3 and C - 20 and their uses as antitumor agents. Mitsunobu, Suzuki reactions and aldol condensation as well as chalcon formation and their application at steroids have been described. The second chapter is concerned with the experimental work which included different synthetic methodology.The third chapter is the main part of the thesis, described the synthesis of new 3? - pregnenolone ester derivatives at C - 3 via Misunobu reaction of the carboxylic acid derivatives, such as : rhodamin B, indomethacin, naproxen, protocatecuic acid, vanillic acid and p - coumaric acid, which showed inversion in configuration at the ester group at C - 3. In addition, the synthesis of 17 - (4 - chloro - chalconyl)pregnen - 3? - ol has been described, which then treated with various substituted phenylboronic acids such as : 2,4 - difluoro - , 5 - carboxy - 3 - nitrop - ,4 - fluoro, 4 - thiomethyl - , 4 - hydroxy - , 2,4, - dimethoxy - , 4 - trimethylsilyl, 2 - triflouromethyl - , 3 - cyano, 4 - ethoxyphenyl boronic acids under Suzuki cross - coupling reaction conditions using Pd(PPh3)4 as a catalyst and Na2CO3 as a base to give the (E) - 3 - (substituted - [1,1’ - biphenyl] - 4 - yl) - 1 - (3? - hydroxy - pregnen - 17 - yl) - prop - 2 - en - 1 - one. Two compounds, 17 - acetyl - 5 - pregnen - 3? - yl) - 2 - (2,6 - bis(diethylamino) - 9H - xanthen - 9 - yl)benzoate, and 17 - ((E) - 3 - (4 - chlorophenyl)acryloyl) - 5 - pregnen - 3? - yl) - 2 - (2,6 - bis(diethylamino) - 9H - xanthen - 9 - yl)benzoate have been synthesized via coupling reaction using DCC as a coupling reagent to afford these ester with retention in configuration, aiming to study their fluorescence properties. Moreover, tritylation of the pregnenolone has been described to protect the alcohol at C - 3 during the structural modification of keto group at C - 20 under basic medium. The structures of all the synthesized compounds have been assigned from their 1H, 13C, and 2D NMR (HSQC, HMBC, COSY, NOESY) spectroscopy as well the as theoretical calculations of the HOMO and LUMO energies of the trans and cis isomers of the chalconyl pregnenolone aryl derivatives to compare them with the NMR data, which showed that trans isomer is energetically more favoured.Furthermore, the flourescence proroperties of the two rhodainyl pregnenolone esters have been studies which one show remarkable quantum yield (?F) in comparison to Rhodamin B itself.The anti - HIV activity of some arylated chalconyl pregnenolone derivatives have been studies and one of these analogues having diflouro substituents exhibited remarkable activity against HIV - 1 and 2. Therefore, the molecular modeling study of this analogue is performed and showed two hydrophobic interactions and one hydrogen bonding with the amino acids residues of the reverse transcriptase enzyme of HIV.

المستخلص: الهدف من هده الدراسة هو تقدير تاثير بعض مشتقات الثياديازول والثيازين الجديدة التحضير على فعالية كل من الانزيمين الكرياتين كاينيز و3 - هيدروكسي - 3 - مثيل كلوتاريل كو - انزيم اي ريدكتيز بالاضافة الى قياس صورة الدهون في مرضى ارتفاع الدهون والفئران المختبرية | The aim of this study is to evaluate the effect of some novel prepared derivatives of thiadiazole and thiazine on the activities of creatine kinase (CK) and 3 - hydroxy - 3 - methylglutaryl CoA reductase(HMGR) in addition to lipid profile in sera of hyperlipidemic patients and in mice induced hyperlipidemia by feeding cholesterol rich diet.The study includes two parts; in vitro study : Sixty individuals with age ranged between (40 - 60) years were enrolled in this study. They were divided into two groups; first group (G1) consists of 30 healthy individuals as a control group with body mass index (BMI) (25.67). The second group (G2)consists of 30 patients with hyperlipidemia and BMI (26.48) which diagnosed by physician. The patients attended the Ibn - Al Naphes hospital during November 2013 to February 2014. Patients with high blood viscosity, diabetes mellitus, renal failure as well as those who are under treatment with statins were excluded. The serum which obtained used in the determination of lipid profile[total cholesterol(Tch),triglyceride(TG), high density lipoprotein(HDL - c), very low density lipoprotein(VLDL - c)], fasting blood glucose(FBG), aspartate transaminase (AST), alanine transaminase(ALT) and C - reactive protein(CRP).Four organic compounds 3 - (4 - (dimethylamino) phenyl) - 2,3 - dihydro - 2 - (3 - nitrophenyl benzo[1,3 - e]thiazin - 4 - one[I], 5 - (4 - imethylamino)benzylideneamino) - 1,3,4 - thiadiazole - 2 - thiol[II], 2 - (4 - dimethylamino)phenyl) - 2,3 - dihydro - 3 - (5 - mercapto - 1,3,4 - thiadiazol - 2 - yl)benzo[1,3 - e]thiazin - 4 - one[III], and N - (4 - (dimethyl amino)benzylidene) - 5 - (isopropylthio) - 1,3,4 - thiadiazole - 2 - amine[IV] were used in this study to test their antihyperlipidaemic ability and their effect on CK and HMGR activities. The results revealed that compounds(III and IV)showed an activation effect in all concentrations on CK and HMGR activities, while compounds(I and II) showed an inhibitory effect in some concentrations for CK and in all concentrations for HMGR. Therefore, compounds (III and IV) were excluded from this study. The results showed that (10 - 4M) for compound I and (10 - 5M) for compounds II give the best inhibition percentage among the other concentrations on CK and HMGR activities which the kinetic study throughout with these concentrations for these compounds. Simvastatin, which considered as standard drug for lipid lowering, was used for comparsion with the potency of compounds I and II on HMGR activity in treatment of hyperlipidaemia. The results showed an inhibitory effect of simvastatin on HMGR activity with percentage inhibition 88%. The effect of compounds (I and II) on ALT and AST were examined in (10 - 4 M) for compound I and (10 - 5M) for compound II in vitro study. The results showed the inhibitory effect of compounds I in concentration (10 - 4 M) and compound II in concentration (10 - 5M) on ALT and AST activities.The Vmax, Km and type of inhibition for compounds I and II on CK and HMGR activities were studied by using Lineweaver - Burk plot. The results showed that also compound I at 10 - 4M was considered to be a noncompetitive inhibitor for CK activity with Vmax values (1000 and 344.82)U/L for uninhibited and inhibited enzyme respectively and Km value (10) mmol/L. The results also showed that compound II at concentration 10 - 5M was considered to be a competitive inhibitor for CK activity with Vmax value (588.23)U/L and Km values (5.51 and 4)mmol/L for the uninhibited and inhibited enzyme respectively.In vitro, the effect of compound (I) with concentration (10 - 4M) and compound (II) with concentration (10 - 5M) were examined in vivo study. The study was carried out with sixty male Wister mice aged seven to eight weeks and theirweight were (180 - 200 g) ,obtained from animal house , in College of Medicine, Baghdad University. The mice were grouped as follow : group one (12 mice) as control group, group(2) : consists of 48 mice in which the mice were daily administered cholesterol (25mg/k/day), in coconut oil 6% and creamy cheese for 28 days. Lipid profile were measured for twelve mice chosen randomly from G2 to diagnosis hyperlipidemia. Then group2 is subdivided into three groups as follows : group (2.A) : (12 mice) as positive control group in which the mice were daily administered simvastatin (40mg /day) as standard drug for hyperlipidemia, group 2B : (12 mice) in which the mice were daily treated with (10 - 4)M of compound (I)via drinking water for 20 days and Group(2.C) : (12 mice) in which the mice were daily treated with (10 - 5)M of compound II for 20 days. The results showed significant elevation in levels of Tch, TG, LDL - c and VLDL - c, while there is significant reduction in HDL - c levels in G2 comparing to control group(G1), after administration of fat rich diet. Simvastatin, compound I with concentration (10 - 4M) and compound II with concentration (10 - 5M) were administrated to G2A, G2B and G2C respectively. Also, the results showed that the activities of CK reduced for group G2B and G2C while it is increased for G2A. The results also showed that the activities of HMGR were reduced in the three treated groups. The results revealed that compounds I and II exhibit more potent antihyperlipidaemic effect than simvastatin. Also, compound I showed more potent antihyperlipidaemic effect than compound II.The results revealed that compounds I and II showed a noncompetitive inhibitor effect on CK with Vmax values(1000and 166.6) U/L for uninhibited and inhibited enzyme respectively and Km value (0.6) mmol/L for compound I, and with Vmax vales (1000 and 250)U/L for uninhibited and inhibited enzyme respectively and Km value (0.84) mmol/L for compound II.In conclusion, the novel synthetic compounds (I and II) seem to be of interest in the development of new antihyperlipidaemic agents that exhibit inhibition effect on CK while statins cause increase in this enzyme. Also these compounds exhibit inhibition effect on HMGR activity more than simvastatin, which is a key enzyme in cholesterol synthesis.

المستخلص: يهدف هذا العمل لدراسة امكانية طلاء سطوح بعض المعادن مثل الفولاذ المقاوم للصدا 316، الحديد الكربوني، النحاس، الالمنيوم والزنك، بالمواد النانوية لتحسين مقاومة التاكل وذلك باستخدام اثنين من التقنيات، الاولى بواسطة الطلاء بالالياف النانوية لمادة متعدد الانيلي | This work aims to study the possibility of coating the surfaces of some metals such as stainless steel 316, carbon steel, copper, aluminum, zinc, with nanomaterials to improve the corrosion resistance using two techniques, first by coating with polyaniline nanofiber using electropolymerization of aniline monomer and the second technique by TiO2 nanoparticles via sol - gel process starting from titanium isopropoxide. The work focused on getting thin and homogeneous layer to cover the entire surface of the metal and protect it from corrosion in artificial seawater solution (3.5% NaCl) at 293, 303, 313, and 323 K.Atomic Force Microscope (AFM), Scanning Electron Microscope (SEM), Energy dispersive x - ray (EDX), x - ray photoelectronic spectroscopy (XPS), and x - ray diffraction (XRD) were used to diagnose and describe the structure and morphology of the layers that cover the surface of the metals under investigation, and finally the corrosion parameters ;corrosion potential (Ecorr), corrosion current (Icorr), protection efficiency (PE%), polarization resistance (Rp) and the effect of temperature on the inhibition efficiency in the absence and presence of polyaniline (PANI) or TiO2 coating at temperature ranging from 293 to 323 K were obtained and expressed as; Ea , ?H*, ?S*, and ?G* of all samples were estimated from Tafel plots using potentiostatic technique.The SEM and AFM images of PANI films reflect nanofibers (diameter from 50 to 70 nm); the thicknesses were measured by special AFM scans. They showed values between )700 to 1564 nm(, which may be attributed to the differences in oxidation - reduction potentials of the metals. The XRD patterns of the deposited PANI showed duplicate broad scattering peaks around 2? of 20? and 25?.The AFM images of TiO2 nanoparticles deposited on specimens revealed that the layer was extremely smooth, the particles are small spherical and the average diameter between 26 and 38 nm.The shifts in Ecorr of the uncoated with comparison of the PANI or TiO2 coated samples were small for; S.S316, C.S, Cu, Al, and Zn which means that the anodic and cathodic reactions affected by the same extent.The Rp of the PANI and TiO2 coated substrate was always more than the uncoated ones that attributed to the weak conductivity of PANI and the semiconducting properties of the Titania. All coated metals with PANI or TiO2 exhibited good degree of corrosion protectiveness. For PANI the PE ranged between 56 and 92 % and the best results was achieved for Zn metal this may attributed to the high corrosion values of the bared Zn, while TiO2 coating showed PE at the range of 68 and 93% and the best was for Al metal. The protection efficiencies showed small changes by increasing the temperature but for TiO2 in some cases the PE somehow increased with increasing the temperature. The data showed that the thermodynamic activation functions (Ea and ?H*) of the corrosion of the coated samples are higher than those of the uncoated ones indicating more energy barrier. The entropy of activation ?S* for the uncoated and coated samples are always negative ,this indicates that the activated complex in the rate determining step represents an association rather than a dissociation step, the measured ?G* values takes positive values and showed almost small change with increasing temperature, indicating that the activated complex was not stable and the probability of its formation decreased somehow with rise in temperature and the ?G* values for coated samples reveal that in the activated corrosion complex becomes less stable as compared to the uncoated specimens.Single cyclic potentiostatic tests conducted at 293 K to follow up the pitting probabilities of each metal in seawater before and after coating. The I - V plots indicated that only SS316 and Aluminium specimens suffer from pitting corrosion and the two types of coating reduces the pitting area of the hysterias loop with pushing the pitting potentials for more positive values

The deposited PPy layer on samples under investigation were examined by Atomic Force Microscope (AFM), Scanning Electron Microscope (SEM), Visible and Ultraviolet Spectroscopy (UV - Vis), Fourier Transform Infrared Spectroscopy (FT - IR), Thermogravimetric Analysis (TGA) and X - Ray Diffraction (XRD).The corrosion parameters are including corrosion potential (Ecorr), corrosion current (icorr), protection efficiency (%PE), polarization resistance (Rp) and the effect of temperature on the inhibition efficiency in the absence and in the presence of PPy coating at temperature ranging from 293 to 323K were obtained and expressed as; Ea, ?H*, ?S*, and ?G* of all samples were estimated from Tafel plots using potentiostatic technique.The SEM and AFM images of PPy films revealed a nanofiber like structure; diameter from 20 to 120 nm, the thicknesses were measured by gravimetric and special AFM scans, they showed values between 1300 to 1450 nm. UV - Vis studies showed that the PPy films exhibit weaker absorption peak at 477 nm and stronger absorption peak at 906 nm and the XRD patterns of the deposited PPy show two peaks around 2? of (43o) and (50o).The shift in Ecorr of the uncoated and of the PPy coated samples are between ( - 600 to - 200 mV) and ( - 200 to 100mV) for CS and SS316 respectively.The protection effectiveness of all PPy coated specimens showed remarkable degree of enhancement, and the %PE ranged between (30 to 80%) for CS and (78 to 96%) for SS316 in all medias.The values of Ea and ?H* of the coated PPy metals are always higher than the uncoated ones which indicate more energy barrier. The negative entropy ?S* for the uncoated and coated samples indicates that the activated complex in the rate determining step represents an association rather than a dissociation step, the measured ?G* values takes positive values and showed almost small change with increasing temperature, indicating that the activated complex was not stable and the probability of its formation decreased somehow with rise in temperature and the ?G* values for coated samples reveal that in the activated corrosion complex becomes less stable as compared to the uncoated specimens.Single cyclic potentiodynamic tests conducted at 293 K to follow up the pitting probabilities of each alloy in all medias before and after coating, the I - V plots indicated that only SS316 in salty media specimens suffer from pitting corrosion and the PPy coating reduces the pitting area of the hysterias loop with pushing the pitting potentials for more positive values

المستخلص: Chapter one : Includes an introduction of the light scattering, types of light scattering and its relation ship to the size of precipitate particles which causing the scatter of light. It also involves an introduction to the concept of turbidity and nephelometry for the scattering of incident light, units of both these, as well as an introduction of light emitting diode. This chapter also describes an introduction to flow injection analysis, its principles of the FIA, dispersion, diffusion law , kinds and application and finally followed with the aims of the project.Chapter two : Comprises a complete description for the chemicals used, their preparations in addition to describe the components of flow injection system.Chapter three : consists of two parts : First part : Describes the design of Ayah 6SX1 - T - 2D solar cell CFI Analyser. Also, a full well clear representation of the expected echanism of what might be happened inside the measuring cell for what was measured whether turbidity solutions (measured reflection of incident light by the presence of precipitate particles surface) or a coloured transparent solutions will act normally as absorbance measurement. In second part : A description for the calculation of dilution factor toevaluate the designed manifold system in continuous flow injection analysis via the chasse and following an air bubble through the whole design. Chapter four : Describes the efficiency and its capability of Ayah 6SX1 - T - 2D solar cell CFI Analyser in distinguishing between precipitated and coloured transparent solutions.For precipitate reaction product gives a positive responses by the effect of reflection , this method is used to determine Cd(II) ion. A method is based on the formation of a yellowish white precipitate for the complex Cd3[Fe(CN)6]2.The linearity of Cd (II) ion is ranged from 0.05 to 12 mmol.L - 1, with correlation coefficient r= 0.9951, limit of detection (LOD) 25.29 ng/sample (3SB)(S/N=3) and the percentage relative standard deviation for 4 and 8 mmol.L - 1 less than 1 % (n=5). This method has been applied successfully to determine a Cd (II) ion in a random river samples. Also provided a comparison between the new method with the classical method (HANNA instrument for turbidity measurement) using the standard additions method via the use of ANOVA - treatments. It was noticed that there is a significant difference at ?=0.05 between the two methods at level < 0.05 was obtained.On that basis the new method can be accepted as an alternative analytical method.While a coloured transparent solutions gives a negative responses, this idea is applied for the determination of vanadium (V) ion. This method is based on oxidation of pyrogallol by vanadium (V) ion in acidic meadium to form color species. The linear dynamic range for the instrument response versus vanadium(V) concentration was 1 - 200 mg.L - 1 with correlation coefficient r = 0.9920. The limit of detection (S/N=3) was 70 ng/ sample from the step wise dilution for the minimum concentration in the linear dynamic range of the calibration graph with RSD % for the repeatability lower than 1% for 90 mg.L - 1 (n=5) concentration of vanadium(V). The method was applied successfully for the determination of vanadium (V) in three river samples. A comparison was made between : two methods proposed method with classical method (UV - Vis spectrophotometry at wave length 427 nm) using the standard addition method via the use of paired t - test. It was noticed that there was no significant difference betweentwo methods at 95 % confidence level. Chapter five : Metronidazole (MTZ) and Mebeverine hydrochloride (MVH) are determined in pharmaceutical preparation as alternative analytical procedures. That were developed by continuous flow injection analysis via turbidimetric (T0 - 180 o).For metronidazole (MTZ), the developed method was based on the formation a greenish yellow precipitate as an ion pair complex by reaction between phosphomolybdic acid with metronidazole in aqueous medium. Linear dynamic of metronidazole is ranged from 0.05 - 8 mmol.L - 1,with correlation coefficient r = 0.9821. The limit of detection (S/N= 3 )(3SB)=171.15 ng/sample from the step wise dilution for the minimum concentration in the linear dynamic ranged of the calibration graph with RSD% lower than 0.5% for 4, 4.5 mmol.L - 1 (n=5) concentration of metronidazole. The method was applied successfully for the determination of metronidazole in three pharmaceutical drugs. A comparison was made between the newly developed method analysis with the classical method (HANNA instrument for turbidity measurement) using the standard additionmethod via the use of t - test. It was noticed that there was no significant difference between two methods at 95 % confidence level. For mebeverine hydrochloride (MVH) is determined by formation of a pinkish banana color precipitate as an ion pair complex between Phosphotungstic acid with mebeverine hydrochloride in aqueous medium.The linearity is ranged form 0.05 to 12.5 mmol.L - 1, with correlation oefficient r=0.9966, limit of detection (S/N=3)(3SB)= 521.92 ng/sample and RSD% (n=6) at 2 and 6 mmol.L - 1 MVH concentration less than 1% was obtained. The method was applied successfully for the determination of mebeverine hydrochloride in three pharmaceutical drugs using standard addition method. A comparison was made between the quoted value and the practically found values for three different kinds of drug by t - test. It showedthat there was no significant difference between the quoted value of each individual company with calculated t - value at 95% confidence interval from developed method.Chapter Six : Summarizes a set of conclusions based on the results of this research work which relates to the use of new patterns and methods for the determination of some analytical species by the developed FIA technique, as well as, some future prospects for the homemade FIA system.

المستخلص: تم استخدام حسابات ميكانيك الكم التقريبية شبه التجريبية وفق نموذج الحساب PM3)) وحسابات ميكانيك الكم الاساسية التامة غير التقريبية وفق نظرية دوال الكثافة (DFT) وباسلوب B3LYP وعناصر قاعدة 6 - 311G لحساب جزيئة الفلرين التي امتلكت التماثل Ih مع وحدات بناءها (5 | Semi - empirical quantum mechanical methods (PM3) and Density Functional theory calculations (DFT/ B3LYP/ 6 - 311G) were executed to evaluate the fullerene molecule ,the internal coordinates (bond length and angles) and some physical and energetic properties.Calculations of the geometrical Parameters (bond lengths and bond angles), have shown that the (C=C) bond length is increased with increasing the size of the molecule that increased elasticity especially to fullerene to be like a ball. The (C - C) bond length is decreased with increasing the size of molecule, that means fullerene will be more stable than the other molecules.The energetic values (heat of formation) is found to be increased with the increasing of the size of molecule. The total energy is decreased with increasing size of molecule that means the stability will increase with the increasing of the size of unit construction of fullerene molecule , on the other hand , the energetic difference (E HOMO - LUMO) between the higher level of orbital and the lower level of orbital are decreased with the increasing of the size of molecule ' unit construction reaching to the fullerene molecule. So, this property will increase the significance of fullerene in the industrial and the electrical purposes.The vibrational modes frequencies with ( 3N - 6) whereas N is represented by number of molecule atoms which are evaluated with the absorption intensities of infrared frequencies. symmetrical and coordinated modes were discussed at the equilibrium geometric formation by using the programs MOPAC & Gaussian 05.It is worthy to say that it was not mentioned before that the complementary classification for the vibrated motion modes for such molecules , so our evaluations may considered unique. It is noted , as well , that CH stretching frequency has had fluctuations that means increasing and decreasing in the values of frequencies. In connected with the bending vibrated modes which taking place out of plane of the molecule are decreased with the increasing size of the unit constructions of molecule but it is increased only at the fullerene molecule. Conversely, the bending vibrated modes which are taken place in the plane of molecule are increased with the increasing the size of unit construction of molecule but are decreased at the fullerene molecule.The distribution of the electronic charges density on the atoms of unit construction of fullerene molecule were studied, the results shown the absence of the electronic charge on the atoms of Fullerene molecule and its concentrated at atoms of the outer circumferential edges C - Cc for the aromatic rings in its own unit construction. Semi - empirical methods (PM3) and Density Functional theory calculations (DFT/ B3LYP/ 6 - 311G) were carried out to evaluate the vibration frequencies and infra - red (IR) absorption intensities for equilibrium geometries of construction units of (6,0) zigzag (Mono (D6h), Di (D6d), Tri(D6h), Tetra (D6d)) ring layers SWCNTs and the internal coordinates ( bond length & angles ) at the equilibrium geometric formation symmetrically according to group theory were evaluated. The most important notes were axial bond length C - Ca which is decreased with the increasing of the tube length whether odd or even number of ring layers. The length of these mentioned axial bonds will be longer in the outer layers than the middle layers that means the increasing of stability of the tube with its length increasing , with the ability of replacing the external atoms of the tube because they are connected with longer and weaker bonds. The reverse was found with the circumferential bond lengths C - Cc was as they were increased with the increasing length of the tube whether the tube was odd or even in number of ring layers. Moreover , the lengths of these bonds are decreased in the middle side to the outer one for the odd and even ring layers. This will confirm the stability of the tube with its length increasing. The lengths of outer bonds C - H which are situated on the edges of the tube which were approximately fixed , with exception of the bond length of CH bonds in Mono ring layers which were longer because the large negative charge on carbon to which it is bonded and the large positive charge on it compared with the positive charge on hydrogen atoms of the multi - layers tubes. The heat of formation which was found to be increased with the increasing of the length of the tube , that means increasing of the stability and the aromatic properties , with the increasing of number of tube' layers. This property will increase the importance in the uses of these tubes for the industrial and electrical purposes as semi - conductors.The vibrational modes frequencies with 3N - 6 with the absorption intensities of infrared frequencies were evaluated and classified. These modes were discussed in symmetrical and coordinating manners at the equilibrium geometric formation, by using the programs of MOPAC and Gaussian 05 , with confirming on unavailability of bounded specification for such modes with 3N - 6 in the literature. We have a through our studies that the stretching vibration modes of symmetric and anti - symmetric Carbon - Carbon axial bond (C - Ca) increased with the increasing length of tube , and this will increase the physical properties for electrical conductivity with confirming on the significance of nanotube industrially. For the vibrational bending frequencies which are taking place in plane and out of plane of molecule surface as well as the vibrational stretching for odd number of ring layers (Mono and Tri) fluctuation will be happening in the relations , as all of them will be decreased with the increasing of tube ' length except (C - Caasym, C - Casym , ? CHsciss. , ? ringasym , ? ringsym and ? ringsym ) which be increased with the increasing the length of tube. The vibrational bending frequencies which are taking place in plane and out of plane of molecule surface for the even number of ring layers ( Di and Tetra layers ) will be decreased with the increasing of tube' length except (? CHsciss.) which is increased with the increasing of tube' length. Furthermore , all vibrational modes which are related to the puckering , breathing and bending movements of clockwise and anti - clockwise according to "group theory" were determined in accurate manner to which deformations are related , which are happened in the tubes , as a result of vibration, that may prevent the flow of electrons' movements and their transitions. The numerical values for the vibrational frequencies which are resulted from Semi - empirical methods (PM3) were acceptable in comparing with the strict calculations , hopping to achieve best values and to be close to the values obtained for the strict calculations (DFT) method to be suited with the basis and standards that are depended internationally. Some of these values were corrected by multiplied by constant scaling factors for such molecules. The results of scaling were good and very close to the experimental and calculated values.The distribution of charges' density on units of construction atoms of (6,0) zigzag nanotube SWCNTs also were studied. The results were consistent with the physical and experimental conductivity properties for such calculated tubes , as the intensity of the electronic charge was concentrated on the outer circumferential edges of atoms C - Cc for the aromatic molecules as well as for nanotubes with its disappearing form outer side towards the middle side of multi - ring layers ( Mono , Di , Tri and Tetra ).

In this context, we think that the present research work will contribute to opening new prospects in designing procedural steps and expands the applications of the cloud point extraction methodology in most important areas, including pharmaceutical sciences, forensic and environmental analyses. The present work concentrates on the developing of new eco - friendly procedures for determination of two selected antibiotic medicaments namely cirprofloxacin chloride (CIPRO) and norfloxacin (NOR) using iron (III) ion in human serums and pharmaceutical formulations, as well as the exploitation of these two drugs in chemical analysis as chelating agents for the detection of iron in pharmaceutical formulations via using cloud point extraction coupled with molecular spectrophometry. Generally, these methods implicate the use of a nonionic surfactant (Triton X - 114) as an extracting medium which entrap the hydrophobic colored complex formed between one of these drugs and iron (III) ion in acidic medium as a reaction system for designing the CPE procedures.This thesis includes three main chapters as follows;Chapter One summarizes some theoretical and practical principles of cloud point extraction (CPE) methods and then highlights the knowledge of the target analytes (CIPRO, NOR and iron) in term of their structures, pharmacological importance besides a concise chemical literature review for the estimation of these analytes by different analytical techniques. Chapter Two consists of an outline of instrumental techniques , general apparatus and chemicals used in the present work. The full analytical procedures for CPE which have been designed for the determination of the target analytes under study are made in this thesis.Chapter Three covers a detailed study for the discussion of the analytical data obtained throughout this work which can be summed up as follows;A. Formation of chelates between CIPRO or NOR and Fe(III) in acidic medium , where the drugs have individually been estimated in the resulting complex by spectrophotometry after the cloud point extraction at each respective ?max, and the use of developed method so that to determine any of the interested drug in human serum and pharmaceuticals. At first, the study was conducted to pinpoint the optimum conditions for the formation of complexes by CPE and the results were as follows; 1. The optimum experimental conditions for Fe - CIPRO and Fe - NOR complex for the determination of CIPRO and NOR respectively : H2SO4 concentration (5x10 - 4 M and 2.5x10 - 4M; Fe(III) concentration ( 6 ?g mL - 1 and 10 ?g mL - 1); Triton X - 114 amount ( 1%) for both drugs; temperature and time ( 75 °C at 25 min and 65 °C at 20 min).2. The achieved analytical figures of merit on applying the developed methods for CIPRO and NOR are : linear range (2.5 - 120 ?g mL - 1 ) for drugs, limit of detection (0.770 and 0.204 ?g mL - 1), Enrichment factor (143 and 280 fold), extraction efficiency (96.46 and 96.62%) and mean recovery percentage (98.89±0.87% and 98.95±1.09). 3. The newly established procedures have been applied for the determination of CIPRO and NOR in human blood serum and pharmaceuticals. For the determination of these medicaments in serum samples , the statistical paired t - test was used to test the significance of the proposed method comparing with the conventional UV - spectrophotometry, while in pharmaceuticals, the findings were compared statistically with quoted values that stated by the manufactures. B. Iron (III) ion was also determined in the pharmaceutical formulations based on the above reaction system in (A) via formation of yellow colored complexes with each medicament which extracted by micelles generated by CPE and subsequently detected spectrophotometrically at the same ?max of the above mentioned complexes. The optimum established conditions and the analytical data obtained could be summarized as follows : 1. The same optimum conditions were used in (A) except that the concentration of CIPRO or NOR here was of 7x10 - 5 M and Triton X - 114 amount of 0.6% in final solutions.2. The analytical figures of merit obtained on applying the developed methods for iron using CIPRO and NOR respectively; linear range (5 - 150 ng mL - 1); limit of detection (2.67 and 3.42 ng mL - 1); preconcentration factor (71 and 83 fold); mean recovery percentage (99.78±0.53% and 98.77±2.29); extraction efficiency (99 and 98.7%). 3. The effect of some additives of the pharmaceutical formulations was also studied and the iron determined in three selected formulations collected from local drugstores. The results were compared statistically with quoted values and shown not to be significant at 95% confidence level.

المستخلص: Corrosion and corrosion protection of carbon steel (C.S) alloy in seawater (3.5% NaCl) was achieved in this thesis. Three types of nanoparticles (NPs) were used to protect C.S the first silicon carbide (SiC), second alumina (Al2O3) and the third zirconium oxide (ZrO2) nanoparticles (NPs). Electrophoretic deposition (EPD) technique was applied to coating the C.S surface. Different polyacrylic acid (PAA) percentage (0.1 - 1)% were added to the suspension solution of coating by the three types of NPs, to improve the protection efficiency (PE%) for the coated C.S surfaces.The corrosion rate with respect to uncoated and coated C.S with the three above NPs were measured. Different corrosion parameters were obtained; corrosion current density (icorr), corrosion potential (Ecorr), cathodic and anodic Tafel slopes (bc,ba), protection efficiency (PE%), polarization resistance (Rp) and the surface porosity (P%). The effect of temperatures (298 - 328)K on the corrosion of uncoated and coated C.S by the three NPs in presence and absence of PAA were also investigated and therefore activation energy (Ea) and preexponential factor (A) were calculated. Thermodynamic parameters ?G, ?H and ?S for all corrosion processes were obtained. Coated C.S were analysed using atomic force microscopy (AFM) to detect the morphology of surface and the particles size of coat layers which range from 60 - 103 nm, which greater than thestarting particles.The corrosion current densities (icorr) were increased generally with increasing temperatures for all cases and icorr reduced after coated C.S by different NPs in absence and presence PAA, therefore icorr reduced from 168.88 ?A.cm - 2 to 19.45, 28.71 and 30.2 ?A.cm - 2 for C.S coated by SiC, ZrO2 and Al2O3 respectively at 298K.While the Ecorr shifted to more active potential after coated by different NPs excepting when C.S coated by SiC in presence of (0.25%) PAA in coating solution suspension where Ecorr shifted to noble direction. The protection efficiency (PE%) of all coated C.S in absence and presence of PAA showed noteworthy degree of enhancement and the PE% ranged between (85 to 99.65)% for SiC , (69 to 91)% for ZrO2 and (77 to 87.9)% for Al2O3. The surface porosity (P%) were increased with increasing temperatures for all cases. The activation energy (Ea) values for the corrosion of coated C.S by different NPs lead to higher values than Ea for uncoated C.S and the highest value was (71.936) kJ.mol - 1 obtained when C.S coated by SiC in presence of (0.25%) PAA. The free energy (?G) Values for the corrosion of coated C.S generally more negatively than uncoated and the values of enthalpy (?H) for the corrosion of coated C.S by ZrO2 and Al2O3 were less negatively than uncoated C.S while coated C.S by SiC lead to more negatively ?H values.

المستخلص: There are a wide variety of polyphenolic compounds named flavonids. These are extensively distributed in plants, and they are considered to be dietary antioxidants. They occur naturally in broad range of vegetables, fruits, and primarily recognized as the pigments.Many flavonoids have a metallic ion complexation capacity. The study of this capacity is important because it can be used in producing nutritional supplements, medicine, and heavy metal detoxification.Chelation therapy is the use of chelating agents (complexing agents) to detoxify poisonous metal such as mercury, arsenic, and lead by converting them to chemically inert form that can be excreted without further interaction with the body.Lead is considered as one of the most hazards and cumulative environmental pollutants that affect all biological system through exposure from air, water and food sources. It is toxic heavy metals which are known to induce a broad range of physiological, biochemical and behavioral dysfunction in humans. Because of its perverseness in the environment, lead poisoning still remains an important health problem.The polarographic measurements were carried out using differential pulse polarography (DPP), at hanging mercury drop electrode (HMDE) at the optimal conditions for flavonoids which were 1M HCl for Quercetin, Rutin, and Hespertin and 0.01M NaOH for chrysin as a supporting electrolyte.A well - defined two electron reversible reduction and diffusion controlled one wave for these flavonoide were observed, a linear relationship between concentration and diffusion current (id) was obtained with the value of correlation coefficient (r2) near to one, this obey Ilkovic equation. The values of n; the number of electrons transferred in the reduction process were obtained from the slop of the straight line corresponding to E vs. log i/id - i.Addition of flavonoides to a solution of Pb (II) ion, show the appearance of a new peak in a more negative potential than Pb (II) peak, with the gradual decrease in id of Pb (II) ion which suggests the complex formation between them.The stoichiometry and the stability constant of Pb (II) complex with flavonoids were calculated by Lingane equation; a plot of ?Ep vs. log [L] give a straight line, the slope of the line allows the determination of the coordination number (p), and the stability constant were determined from the intercept, the stoichiometry of these complexes were (1 : 1) with a stability constant of : Pb - Quercetine (5.5*107) ? Pb - Rutine (1.3*107) ? Pb - Hespertine (4*106) ? Pb - Chrysin (5.4*104)These measurements also includes the determination of the kinetic parameter of the electrode reaction (Kth, ?n) and the thermodynamic parameters such as ?H, ?G, and ?S.The spectrophotometric measurements were carried out in 50% methanol/water for Quercetin and Rutin, 30% methanol/water for Hespertin and in phosphate buffer of pH - 7 for Chrysin.The electronic spectrum of free flavonoides in methanol solution was mainly characterized by an important absorption band at ? 370 nm (band I) and a second one located at ? 256 nm (band II). Upon addition of lead (II) to the flavonoids solution significant changes are observed in the electronic spectra, a bathochromic shift in band (I) to the extent of ? 40 nm and a shift in band (II) to the extent of ? 7 nm, the change in ?max and the change in the intensities of the bands were due to the coordination between flavonoids molecules and Pb (II) ion.The stoichiometry of the formed complexes were investigated by the method of continuous variation and it were found (1 : 1), the stability constant were calculated also and were found to be in the order of ? 105 to 106.Thermodynamic parameters and kinetic studies were also determined which indicates a second order interaction between lead (II) and these flavonoides.Spectroscopic measurements for (EDTA) Complexation with lead (II) were carried out in order to compare its stability constant with that obtained for flavonoides complexes, due to its application in the treatment of metal poisoning.Stability constant of (EDTA) with Pb (II) complex were in the order of 108 which is much more efficient than flavonoides.

المستخلص: هذه الاطروحة تمثل سلسلة من دراسات الكم من خلال التركيب الالكتروني للانظمة العضوية الفلزية. تتضمن نتائج الفصول خلاصة عمل تعود لكيمياء الروثينيوم (الفصل الثاني) واستخدام النظريات لتساعدنا على التشخيص التركيبي من خلال اجهزة الطيف الحاسوبية (الفصل الثالث والر | This thesis presents a series of quantum chemical studies into the electronic structure of organometallic systems. All of the results chapters are self - contained, summarising work related to Ruthenium chemistry (Chapter 2) and the use of theory to aid structural identification through computation of spectroscopic parameters (Chapters 3 and 4). Chapter 5 relates to distinct work done concerning to the Topological Analysis of the Electron Density in the dihydried Triruthenium Cluster, but the focus on the question of dihydried triruthenium motif represents a close link to the material covered in Chapters 3 and 4. In Chapter 2, Density Functional Theory (DFT) is used to probe the structures of triruthenium clusters Ru3(CO)12. The researcher shed light on the equilibrium geometries and the best function (PBE1PBE) and basis set (SDD Ru/ SVP on (C, O)) can be used. On the basis of that, the global minimum found for Ru3(CO)12 is an unbridged (1D3) structure. In Chapter 3, DFT with PBE1PBE functional and (SDD Ru/ IGLOIII, TZVP P, H/ SVP on (C, O)) basis sets have been used to identify structures of species observed in hydrogenation reactions of alkynes using catalysts based on Ru3 clusters. The identification of the hydride intermediates observed by NMR spectroscopy is ambiguous, and is generally based only on 1H NMR and JP - H coupling constants for hydrides attached to the ruthenium metal centres. Our calculations propose that the experimentally observed species A and B do not contain the Ru3(? - H)(H) motif, as proposed by Duckett group but have Ru3(? - H)2. In Chapter 4, these studies were extended to the analogous dihydride triruthenium monodentate and bidentate phosphines. By computing energies, 1H chemical shifts, we propose that the experimentally observed species A1 and B1 do not contain the Ru(µ - H)(H) motif, as proposed by Duckett and co - workers, but rather the dibridging Ru(µ - H)2 structures common to A2 and B2. In addition, the results confirm that our methodology is able to model the environment of a terminal hydride correctly.Finally, Chapter 5 describes the Quantum Aim (QTAIM) topological analysis of the electron density in the Picolyl N - Heterocyclic Carbene Triruthenium cluster [Ru3(? - H)2(?3 - ?3C2,NHCpyCH2ImMe)(CO)8] (3 - methylimidazol - 2 - ylidene). However, this cluster has been chosen since, firstly, has Ru3(? - H)2 motif similar to triruthenium core proposed in chapters 3 and 4 , secondly, this particular cluster contains one hydride - unbridged and two hydride bridged Ru - Ru edges and a face - capping ligands with different types of Ru - C and Ru - N bonds , this allowing interesting comparisons between the topological properties of related but different atom - atom interactions, within the same molecule.

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: The Fibroblast associated (Fas) system in the testes has been identified as a key regulator of apoptosis, a process that greatly influences the germ cell population of the testes. and the soluble Fas Ligand (sFasL) may be a competitive inhibitor to induce apopto¬sis of the Fas baring cells. Therefore, this study measures the level of sFasL in the semen of oligozoospermic men evaluating the association between seminal plasma sFasL and spermatogenesis.A total 58 oligozoospermic men and 29 normozoospermic volunteers were included in this study. They were attending the Infertility Clinic of the High Institute of Infertility Diagnosis and Assisted Reproductive Technologies, AL - Nahrain University\ Baghdad. Their age mean was 31.77± 5.48 years and a median of 30 years. Semen samples were evaluated according to World Health Organization 2010 standard parameters. The Seminal plasma was separated from the cellular elements after centrifugation and the supernatant was transferred to plane tubes and frozen at - 20 ?C till using for measurement of sFasL. These patients were classified into patients with severe oligozoospermia (sperm concentration ?5 million / ml) which include 29 patients, and patients with mild and moderate oligozoospermia (sperm concentration ranging between 5 - 15 million / ml) which includes 29 patients as well. The control group comprised of 29 men with normospermic parameters according to WHO 2010 standard (Normal volunteers). The sFasL was measured using ELISA enzyme immunoassay for quantitative determination of sFasL Kit. Data were analyzed statistically using Analysis of variance (ANOVA), Least Significant Difference (LSD) and Correlation Coefficient (r).The sFasL level was found significantly higher (P< 0.01) in seminal plasma of oligozoospermic men, with weak correlation of the level of sFasL with the degree of severity of oligozoospermia. Based on the results of this study, it was concluded that sFasL is a novel marker found in the seminal plasma of oligozoospermic men. It's level was higher in cases of oligozoospermia regardless of its severity.

المستخلص: Two field experiments, several greenhouse and laboratory experiments were conducted during the course of study to evaluate the allelopathic potential of two sunflower (Helianthus annuus L.) cultivars on companion weeds and weeds grown in mungbean (Vigna radiata L. R. Wilczek) field alone and in combination with reduced rate herbicide, and to determine the chemical and genetical bases of allelopathic traits in the test cultivars. The aim of the first experiment was to test whether the variation in weed growth between the sunflower cultivars (Shumoose and Sin Altheeb), which was observed in the field, was due to differences in their allelopathic potential. Results showed the ability of both cultivars to reduce weed population and biomass with the superiority of Shumoose cultivar in suppression of weed density at 60 and 120 days after sowing compared to Sin Altheeb. Weed biomass was significantly reduced up to 90 and 71% by Shumoose and Sin Altheeb cultivars, respectively. Stair case experiment indicated that root exudates of Shumoose cultivar showed more suppression to weeds than Sin Altheeb giving additional evidence for the superiority of Shumoose cultivar in its allelopathic weed suppression. Chemical analysis by High performance liquid chromatography indicated the presence of 9 compounds in root exudates of Sin Altheeb and 8 compounds in Shumoose, and all are Phenolic in nature. However, total of the isolated phenolics was doubled in Shumoose than in Sin Altheeb. Most of the isolated chemicals are reported to have inhibiting ability for germination and growth of plants, including weeds. Second field experiment was undertaken to explore the response of weeds and mungbean crop to soil incorporated with sunflower residues in combination with lower rate of a pre - plant herbicide (trifluralin). Sunflower residues of the two cultivars Shumoose and Sin Altheeb at 3.2 and 6.4 t ha - 1 were used either alone or in combination with trifluralin at 1.2 L ha - 1 (50% of label rate). Weedy check (control), trifluralin at full label rate (2.4 L ha - 1), and weed free treatments were also included for comparison. Plots treated with 50% of label rate of herbicide and amended with sunflower residues of cultivar Sin Altheeb recorded least weed density and dry biomass and this suppression was much greater than the residue treatments alone and more than cultivar Shumoose. Application of herbicide at 50% rate in plots amended with Sin Altheeb residue resulted yield 64 % more than with the label rate of herbicide treatment. Chromatographic analysis of sunflower amended field soil revealed the presence of several potent allelopathic compounds in the residues of both cultivars with greater quantity (355.5 µg/ml) in Sin Altheeb than in Shumoose (250.9 µg/ml). Dynamics of release, decomposition and degradation of allelochemicals into the soil showed that different compounds exhibited differential behavior for these processes. Overall quantity of allelochemicals started to increase after 2 weeks of decomposition and peaked at 4 week of decomposition (180.1 ppm) then declined sharply in their quantities thereafter. Periods indicating higher quantities of total phenolics as shown by chromatographic analysis was coincided with the periods in which higher suppressive activity against weeds grown under field conditions. Bioassay of sunflower residues decomposed in soil at different times on Echinochloa colonum L, one of the weeds dominated the mungbean field, revealed that residues of both cultivars suppressed growth of E. colonum weed. The phytotoxicity started after 2 weeks and persisted for 8 weeks. However, Sin Altheeb residues showed greater inhibition than Shumoose cultivar at the last three decomposition periods. Shumoose residues recorded appreciable reduction to the growth of test weed compared to Sin Altheeb. The effect of residues of both cultivars on chlorophyll content and ions uptake in Amaranthus retroflexus L. weed revealed that residues of both species reduced chlorophyll content of leaves and the reduction increased with the increased residue rate. Sin Altheeb cultivar residues were more inhibitory than Shumoose at the lower residue rate. In the same weed, ions uptake was significantly averted by the residues of both cultivars. P and K was significantly increased over control, while Ca, Mg an Fe were found to be decreased over control due to application of sunflower residues in soil at 8 g per kg soil. N was the only test element that did not significantly influence by the residue treatments. No significant differences were found in the test ion uptake between the test sunflower cultivars. Results of using RAPD technique on the sunflower genomic DNA revealed that all the 19 primers used in this study scored different amplification monomorphic and polymorphic bands in the tested genotypes with 12 primers generated polymorphic bands. These bands present in one cultivar and absent in another. They could be responsible for allelopathic trait or secondary compounds associated with this phenomenon. Further work is recommended to analyze the sequence of this band to find out whether it is related to allelopathic trait or not.

المستخلص: Hepatitis E Virus (HEV) infection is found worldwide. It is responsible for large outbreaks in East and South Asia. This study was carried out to identify the distribution of acute HEV infection in AlMuthanna province and then determine the genotypes responsible for the disease spreading. This is the first investigation about the occurrence of hepatitis E genotypes in Al - Muthanna province patients. The study included 270 jaundiced patients of both sexes From AlMuthanna province which included out patients in public health laboratory in Samawah city, for the period from October 2013 to June 2014. All these patients were tested for anti - HEV IgM antibodies by using enzyme linked immunosorbent assay (ELISA). In Al - Muthanna province, 72 patients (26.66 %) out of 270 patients showed positive results for anti - HEV IgM antibodies, and all those patients were tested for confirmatory test at central public health laboratories (CPHL) in Baghdad province. Those patients consist of 45 females and 27 males with age ranged between (4 - 74) years old, were all negative for routinely screened markers of Hepatitis A, Hepatitis B and Hepatitis C, Ten normal healthy individuals, used as normal control in this study. This study showed that the HEV IgM is more common among younger age group (15 - 24), with a percentage of) 41.67%(, and it was higher in females (63%) than in males (37%). Highly significant differences (p ? 0.01) appeared among age groups. The levels of liver function enzymes demonstrated significant differences (p ? 0.05) in HEV patients as compared with healthy controls. The levels of Total Serum Bilirubin (TSB) were (23.41 ± 12.38) mg/dl, Serum Aspartate transaminase (SAST) were (887.17 ± 9.87) U/l, Serum Alanine transaminase (SALT) were (859.91 ± 13.28) U/l, and the levels of Serum Alkaline phosphatase (SALP) were (206.56 ± 5.04) U/l higher than healthy controls (0.884 ± 0.05) mg/dl, (37.27 ± 4.58) U/l, (34.14 ± 7.63) U/l, (48.09 ± 15.42) U/l respectively. RNA was extracted from sera of positive anti - HEV IgM antibodies by using a QIAamp® Viral RNA Mini Kit. Nanodrop and Quantus™ Fluorometer instruments were used to determine the RNA yield and purity according to the standard kit protocol. High levels of RNA concentration were measured by Nanodrop and Quantus™ Fluorometer. Forty - six samples have high RNA concentration out of 72 samples were detected for genotypes I, III & IV by using Applied Biosystems Real time PCR 7500 machine. In this study, HEV type I and III were detected in 23 samples out of 46 samples by using Real Time PCR systems. Ten samples were positive for this test. Thirteen samples (56.52%) were negative for this test. The distribution percentage of genotypes I and III was (43.48%). The results appeared significant difference (P ? 0.05). Also by using the same technique (Real time PCR systems) the HEV type IV was detected in 23 samples out of 46 samples. Which included, 13 samples that recorded negative results by I & III genotypes kit and only 2 samples from it recorded positive results and 11 samples recorded negative result for HEV genotype IV. From other 10 samples, only 3 samples recorded positive result and 7 samples recorded negative result for HEV genotype IV. In a total, 5 samples were positive for HEV genotype IV and 18 samples (78.26%) were negative. So that the distribution percentage of genotype IV was (21.74%). In this study, the samples that showed negative results in both kits have not been tested for other genotypes. This study indicated that the acute HEV infection is highly endemic in Al - Muthanna province in Iraq. Genotypes I & III were the most distribution than genotype IV in patients from Al - Muthanna province in Iraq. These results suggest that the genotypes I & III are the main causative agents of sporadic HEV infection in Al - Muthanna province

المستخلص: Breast cancer (BC) is the most common cause of cancer - related deaths in women. It continues to rank as one of the top killer of women. This cancer increased in frequency in the last years in Iraq. The aim of this study was to shed light on the immunohistochemical for some factors that could be affect on development of microenvironment in breast cancer of Iraqi patients. And these factors include CD133 as a marker for breast cancer stem cells (BCSs), and also studying tumor necrosis factor alpha (TNF - ?) and transforming growth factor beta (TGF - ?). 53 samples Formalin - fixed, paraffin - embedded (FFPE) wax block appeared their ages were range from 29 - 70 year with a mean age of 48.45 years. 32 patients with breast carcinoma and 21 patients with benign breast lesions were included in this study for comparison. The results of this study show that the CD133 positive expression was found in (56.2%) of Iraqi breast cancer cases. Also the result of this study show that (62.5%) positive expression from both (TNF - ? &TGF - ?) of breast cancer cases, compared with sample of benign breast lesion. The results show (52.3%) positive expression of TNF - ? and (28.57%) positive expression of TGF - ? of samples with benign breast lesion, there is a significant different between studied samples, compared with (19.05%) samples positive expression of CD133 of sample with benign breast lesion so there is a significant different between the samples with breast cancer and benign breast lesion. Also the results show there is a positive relationship correlation between (TGF - ?) expression and (TNF - ?) expression, while there were no relationship correlation between (TGF - ?) and CD133 and no relationship correlation between TNF - ? and CD133. The results show there is a positive correlation between the grade and breast cancer with the three different expressions of marker but in different strongest correlations between (TNF - ?) and (TGF - ?) with the graded but this correlation becomes weak with CD133 marker the value of significant. According to the relationship in breast cancer case in this study between the studied markers and stage of case it shows (TNF - ?) has a strong positive correlation while the correlation appear week between the stage of this studies case and end each of TGF - ? and CD133. For this we concluded from the results there high expression of CD133 and TNF - ? indicators and TGF - ?. CD133 could use in diagnosis of the cancer cell and the high expression of TNF - ? & TGF - ? indicate that these factor play important roles in tumor microenvironment metastasis. And the strong correlation between the expression of these markers with grade and stage of breast cancer

المستخلص: داء السكري مرض واسع الانتشارعالميا تختلف نسبة الاصابة بين البلدان المتطورة والنامية ويعتبر المسبب الرئيسي للاعاقة والموت في العالم.داء السكري النوع الثاني هو الاكثر حدوثا حيث تبلغ نسبة الاصابة (90 - 95%) من مجموع المصابين بالسكري للانواع الثلاثة الرئيسية. | Sixty of non insulin dependent diabetes mellitus (NIDDM) patients who were diagnosed according to American Diabetes Association criteria (ADA) 2007 were selected from the specialized center of endocrinology and diabetes (Baghdad AL - Russafa Health Directorate) during the period between first of May 2013 to last of October 2013.Their age ranged 35 - 70 years. Fourty apparently healthy individuals their age ranged (35 - 70) years were considered as control. Enzymatic colorimetric methods used for measured FBS (fasting blood sugar) and HbA1c (glycohemoglobin) and enzyme linked immunosorbent assay (ELISA) for hormones and enzyme markers. Fasting blood sugar revealed high significant in patients with median (11.6 mmol/L vs. 5.9 mmol/L) and (P<0.001) in comparison to control groups.Elevation of glycated hemoglobin (HbA1c) with mean (9% vs. 5.5%) in comparison to control groups. Another reliable marker are the concentration Adpionectine hormone, Insulin hormone and adenosine deaminase activity the results of those estimated significantly difference between levels mean (20.7 vs. 34 ng /ml) in patients compared to healthy subjects (P<0.001) for adiponectin ; mean (106.6 vs. 59.3 ng/ml) for ADA (adenosine deaminase) with (P<0.001) and the median (12.1 vs. 16 uIU/ml) for insulin hormone with (P 0.001). In order to investigate the accuracy of previously mentioned tests, a statistical analysis [Receiver - Operator Characteristics (ROC)] has been applied to show the accuracy, specificity and sensitivity of the tests under test.This analysis revealed that serum ADA activity is the best marker with highly specificity 100%, sensitivity 100%, and accuracy 100% while; FBS was the best test with highly specificity 100%, sensitivity 100% and 100% accuracy in comparison with other tests. It was denoted that type2 DM was associated with certain HLA class II alleles were analyzed for their genotyping by Polymerase Chain Reaction - Sequences Specific Olegionucleotide (PCR - SSO) technique. The present study revealed that diabetic patients were positively associated with HLA - DQB1*0201 (83% vs. 5.0%) which is the most prevalent in patients followed by DRB1*1137 (46.7% vs. 0.0%); DRB1*0401 (41.7% vs. 2.5%), and DRB1*1306(15% vs.0.0%) while HLA, A*0201;B*3559;Cw*0410 and DQB1*0501 is negatively associated in type 2DM in comparison with healthy control groups.This study has shown that there is no significant association between FBS, HbA1c, serum insulin, HOMA2(Homeostatic Model Assessment2) ? - function, HOMA2 - IR, serum adiponectin, serum ADA and HLA alleles(DQB1*0201, DRB1*1137, DRB1*0401, DQB1*0501, DRB1*1306) in spite the significant associated between FBS and serum ADA and HLA - DRB1*0701 allele with (P 0.021, P 0.008) respectively.The current result concluded that there may be an important role for HLA genotyping in arising the chance for enhancing the susceptibility for either disease development or protection against its initiation.

The samples of the study have been collected monthly for water and zooplankton for the period from March 2012 till February 2013 at four selected stations in the river; the first is located in Al - Kufel city, the second in Al - Kuffa city, the third in Aboskeer city and the four after Al - Mushkab city. The study was achieved by measurement of some physical and chemical properties of water were analyzed based on the importance of these parameters the parameters studied included Air temperature, water temperature, pH, water current velocity, turbidity, total suspended solids, electrical conductivity, salinity, total dissolved solids, dissolved oxygen, percentage of saturation, biological oxygen demand, total alkalinity, total hardness, calcium, magnesium, chloride, sulphat, phosphate and nitrate. The study also included biological aspects using density, Rrelative abundance index (Ra), Constancy index (S), Species richness index (D), Shanon - Weiner index (H), Species uniformity index (E) and Jaccard presence - community were also employed to determine the values of species composition, density and zooplankton biodiversity in the study area. The results showed clear consensus from air temperature and water temperature in all study locations.Air and water temperature ranged from 6 to 41 ?C and 7 to 34?C respectively, the Water current velocity values were fluctuated according to the different water levels during the study period and ranged from 0.19 to 0.71 m/sec, while the (TSS) values were low and ranged from 3.54 to 52.05 mg/l, and turbidity 1.69 to 55.76 NTU, the pH values were neutral tend to light alkaline and ranged was ranged from 7.1 to 8.7, The electrical conductivity values varied from 810 to 1810 ?s/cm, according to the values of salinity 0.51 to 1.158 ‰ the water of the river was classified as Oligohaline, (TDS) showed medium values ranged from 440.4 to 977 mg/l. This study showed that river were well oxygenated the dissolved oxygen values ranged from 5.5to12.2mg/l and high percentage of saturation recorded from 72 to 148 %, The study recorded values to the BOD5 were ranged from 0.9 to 6.4 mg/l.The study showed that the water of the river was classified as slight alkaline and bicarbonate ions were dominant throughout the study period according to the values of total alkalinity from110 to 210 mg CaCo3/l, and the river water classified as very hard according to the total hardness values from 237.9 to 538.2 mg CaCo3 /l., While the concentrations of calcium and magnesium were from 73.19 to134.1 and from10.46 to 55.59 mgCaCO3/L respectively, The chlorid and sulfate values were from117.6 to 244.5 mg/l and136.9 to 528.14mg/l respectively, The nutrients showed clear fluctuation in their concentrations, nitrate values were varied from 3.55to36.43?g/l and phosphate values were from 0.15 to 2.89 ?g/L.. In the current study about 164 Taxonomic units of zooplankton were identified, the rotifer was dominate group including 92 taxa to rotifera, 35 taxa belonging to cladocera and 37 taxa to copepod. The Zooplankton showed high density in river 29470 ind /m3 during April 2012 while lower1100 ind/m3 in December 2012 also the rotifer recorder density from 425 to 17925 ind/m3, cladocera density from 25 to 4850 ind/m3 and copepod density from 300 to 15450 ind/m3 the high values were in spring and autumn while lowest values were recorded in summer and winter. The results of relative abundance index showed that the species rotifera : Keratella cochlearis, K.valga, Euchlanis delatata while the cladocera Alona rectangular, Bosmina longirostris, Chydorus sphaericus, Simocephalus vetulus and the copepods : nauplii were more abundant in the kuffa river. also the results of Constancy index showed fourteen taxa belonged to zooplankton which were considered "Constant" at stations However the other taxonomy units varied from "accessory" and "accidental" taxonomy units in study stations he Values of the index of Species richness of Rotifer varied from 3.42 to18.26 and Cladocera varied from 0.9 to8.13 and Copepod from1.46 to 6.13 with greatest values were recorded in April While lower values in September and June The highest percentage of similarity 70.58% for Zooplankton were reported from stations 3 and 4 in and lowest similarity reaching 50.30% from stations 2 and 3. the Shanon - Weiner index of total Zooplankton varied from 1.81 to 4.13 bit/ind while the Shanon index of Rotifer from 1.85 to 3.78 bit/Ind, Cladocera varied from 0.001 to 3.03 bit/Ind and Copeoda varied from 0.35 to 2.71 bit/Ind with greatest values were recorded in April 2012 and September 2012 While lower values in and June 2012 and January 2013, The uniformity index of Rotifer varied from 0.01 to 0.9, Cladocera from 0.01to 1 and Copeoda from 0.14 to 0.88 These high values indicate that there is no ecological stress on zooplankton in the study area. The results of the Canadian Water Quality Index (CCME WQI) for aquatic life showed that the water quality of River Kuffa in the study area obtained good to marginal level (90.93 - 62.76) the highest value was recorded at station 1 through April 2012 and lowest value was recorded at station 2 through July 2012

The number of scabietic patients who attended the outpatient clinic during February to November 2012 were 300 (168 males and 132 females). Their ages ranged from 10 to 65 years. They were included to show the prevalence of scabies. Sixty scabietic patients (out of 300 patients) who did not have allergic diseases, helminthic infections, previous attack with scabies, and/or getting any antihistamines drugs were included for human IL - 1?, TNF - ?, IL - 4, IL - 5 and total IgE assays using ELISA technique; superoxide dismutase (SOD) activity assay and eosinophils(%). These assays were applied on scabietic patients (who were divided according to onset of symptoms or duration of scabies symptoms into early and late scabietic patients) as well as healthy controls.Also Sarcoptes scabiei mite proteins were extracted. Then heat stable mite proteins concentration was determined by Bradford’s method. SDS - Polyacrylamide Gel Electrophoresis (SDS - PAGE) analysis was used. The activity of mite allergens was assayed by skin prick test (SPT) in 10 scabietic patients and 5 controls with 1.2 ?g/ml and 2.4 ?g/ml. House dust mite (HDM) antigens were skin prick tested in patients with scabies and controls.The prevalence of scabies in current study constituted 6.54% from all the dermatoses which attended the clinic. The males represented 56% and females were 44%. The age group (10 - 19) years was the highest prevalence of scabies (41.7%). Early scabietic patients represented 72% versus late scabietic patients were 28%. The results revealed that a highly significant elevation (p< 0.001) in serum cytokines (IL - 1?, TNF - ?, IL - 4 and IL - 5) as well as IgE, SOD and eosinophils (%) in the two groups of scabietic patients in comparison to the controls.Results of correlation demonstrated that IgE, SOD and eosinophils (%) were positively and significantly correlated (p< 0.001) with the studied cytokines in early, late scabietic and control groups. IgE was positively correlated with IL - 1?, TNF - ?, IL - 4 and IL - 5 in early scabietic patients, whereas, it had negative correlation with IL - 1?, TNF - ?, and positive correlation with IL - 4 and IL - 5 in late ones. SOD showed negative correlation with IL - 1? and TNF - ?, and positive correlation appeared with IL - 4 and IL - 5 in both scabietic patients. Eosinophils (%) were positively correlated with all the studied cytokines in two groups of scabietic patients.The results also revealed that SDS - PAGE profile of the parasite heat stable proteins consisted of protein bands with molecular weights ranged from less than 10 to over than 100 kDa. Skin test demonstrated that (7/10, 70%) and (8/10, 80%) of scabietic patients had a positivity against 1.2 ?g/ml and 2.4 ?g/ml of sarcoptic mite extracts, respectively when prick tested. HDM extract was found to be positive in (4/10, 40%) of scabietic patients; while controls revealed negative result.It can be concluded that scabies affect TH1 and TH2 immune response as well as SOD activity and eosinophils. Sarcoptic proteins contain heat stable allergens which able to cause immediate type - 1 hypersensitivity when 1.2?g/ml of mite protein is skin prick tested, and there is a cross reactivity between Sarcoptes scabiei and HDM allergens

A sample of 945 fish of Barbus grypus and Liza abu has been examined. It was found that 205 of the Barbus grypus fish and 344 of the Liza abu were infected with parasitic intestinal worms. Some parasitic intestinal worms have been detected such as the Neoechinorynchus iraqensis in both fish types. The female paulisentus in Barbus grypus, Bothriocephalus acheilognathi were found in both Barbus grypus, Liza abu and the larva of Contracaecum spp was seen in the Liza abu and Barbus grypus type. In Diwaniya river had high infection of both fish types was 61.31%. The Barbus grypus fish were recorded with 70.11% while the Liza abu fish infection was 57.21%.. In Hamza river the total percentage of infection was 56.79 % in both types. The Liza abu infection in the four parts of Diwaniya as 56.30%. In September the infection percentage was higher by 63.21% in the two kinds of fish. while in February, December the infection rate was as low as 50%. It was also found that length categories of (26 - 24.1)cm of Barbus grypus had high percentage of 67.16%, while the length category (28 - 26.1) cm suffered 64.47% infection with intestinal worms in the length category (> - 30.1) was 22.22%.As for the Liza abu it had a high percentage of infection in length category (12 - 10.1) cm, the percentage was 67.53% and dropped to 46.53% in length category (8 - 6)cm.The present study has discovered many pathological changes (visable and microscopic)caused by the intestinal worms, Among the visable changes was embolism and bleeding of the walls of the infected intestinal microscopic changes included an increase in the phlogistic and phagocytic cell and ruining of the internal tissue lining the intestines and atrophy villi.Eight heavy metals were measured.They included Cadmium, Lead, Zinc, Nickel, Copper, Manganese, Mercuryand Chromiumby means of an atomic absorption spectrophotometer tissues from the a forementioned types of fish were measured for these heavy metals these tissues were from the liver, muscles, gills, two kinds of intestinal worms (Cestode and Nematode) were measured also water and sediments (deposits) from four districts of Diwaniya throughout the year, Cadmium registered high concentrations in autumn (12.67) Mg/ gm in the liver of the Barbus grypus. lower concentrations of Cadmium were registered in Winter (1.30) Mg/ gm in the liver of Liza abu.The Barbus grypus livers had high concentrations of lead in autumn (21.03) Mg/ gm in Hamza rivers, where as gills of the Liza abu registered lower concentrations(6.43) Mg/gm in spring.The livers of the Barbus grypus registered high concentrations of zine in autumn which where (32.27)Mg/ gm in Hamza river. Shamiya river they dropped to 21.17 Mg/ gm in spring, It was observed that Nickel had high concentrations in the livers of both fish types, The highest of which was in autumn, the the Hamza river had the highest concentrations in autumn which were (29.17, 28.63, 27.67) Mg/gm.In spring the nickel concentrations were low in the gills of the Liza abu11.10 Mg/ gm in Shamiya river, The livers of the Barbus grypus had the most concentrations of copper which reached 2.02 Mg/ gm while livers of the Liza abu had 1.92 Mg/ gm concentrations in autumn in Hamza river.Manganese showed low concentrations in the Liza abu gills in winter and spring they ranged (1.67, 1.73) in Shamiya river, manganese concentrations increased in autumn and summer to reach (14.83, 10.07) Mg/ gm in the Liza abu liver and (15.13, 10.57) Mg/ gm in the muscles of the Barbus grypus in Hamza river, Marcury had the lowest concentrations 24.37 Mg/ gm in the gills of Liza abu in Afaq river, It was observed that the livers of the Barbus grypus were more vulnerable, the highest concentrations was registered 49.97 Mg/ gm in Hamza river followed by Diwaniya which registered 48.97 Mg/m in autumn. Chromium registered lowest concentrations compared to the other metals,.cestodes isolated from the Barbus grypus registered high of mercury concentrations that reached 37.667 and 37.300 Mg/ gm in Hamza and Diwaniya rivers, chrome concentrations was low in the tape worms 0.166 Mg/ gm while nematodes, the concentrations was 0.157 Mg/ gm in Shamiya river.cestoda and nematodais isolated from the intestines of Liza abu registered high concentrations in autumn, cestoda had the most of the concentrations of heavy metals, Mercury and nickel had high concentrations of (35.783, 25.840) Mg/gm, copper and chrome had lower concentrations(1.881, 0.174) Mg/gm inHamza river, nematode registered high concentrations that reached 33.994 Mg/ gm in mercury in Hamza river.As for the rivers sediments Autumn was the most effected by heavy metals for the sediments in Hamza river had high concentrations in Manganese, mercury, and chrome (367, 376.97, 290.93) Mg/ gm respectively while the lowest concentrations was for copper 22.53 Microgram/gram in Shamiya river in spring. The rivers water registered low concentrations of heavy metals in spring, The Shamiya river had low concentrations of lead and cadmium (80.57, 54.60) Mg/gm, autumn registered higher concentrations compared to spring where the highest concentration of manganese and Copper was (512.37, 442.83) Mg / gm in Hamza river.

المستخلص: يعد الكبد العضو الرئيسي المسؤول عن ازالة السموم في الجسم, مما يجعله الاول في التعرض للسمية الدوائية والكيميائية للمواد الداخلة للجسم من جميع الاعضاء, ووفق ذلك اجريت هذه الدراسة لمقارنة التاثير الحامي للكويرسيتين ومستخلص الحلبة على الانسجة الكبدية لذكور ال | The liver is the main organ responsible for removing toxins in the body, making it the first to face various chemicals from all of the organs, and according to this the study had designed to compare the hepatoprotective effect of the Quercetin and Trigonella foenum graecum extract on the liver tissues of male rats poisoned with carbon tetrachloride, and to know their effects when used together. The study was conducted at the Faculty of Pharmacy - University of Kufa, and included using of 30 rats from Sprague - Dawley divided into five groups : the negative control group, the positive control group, the group treated with organic extract, the quercetin treated group and the group treated with extract and quercetin together. The period of dosing continued for 7 days and on the eighth day all groups(except the control group) were poisoned with carbon tetrachloride. After 24 hours the animals were killed. The study lasted from April 2013 - until July 2013. The Liver weights of treated animals were measured, the effectiveness of transferase enzymes Alanine Transaminase, Aspartate Transaminase and Alkaline phosphatase and total bilirubin level in the serum were assessed, also the Glutathione and Malondialdehyde levels were estimated in liver homogenized. The results showed the following : A significant increase (P<0.05) in the liver weights, the effectiveness of the amine transferase enzymes, Alkaline phosphatas and total bilirubin in the serum of the treated animals when compared with the negative control group, while these parameters revealed a significant decrease (P<0.05) at the treated groups as compared with the positive control group. The results showed no significant difference (P>0.05) in the Glutathione level and a significant increment (P<0.05) in the level of Malondialdehyde in the treated groups when compared with the negative control group. Also, the results showed a significant decrease and increase (P<0.05) in the levels of Glutathione and the Malondialdehyde at the treated animals as compared with the positive control group. The present study showed numerous histological changes which resulted from the injection with carbon tetrachloride. In relation with the tissue sections which have been taken from the treated groups : with the extract, quercetin and the group treated with both revealed a protective effect for organic extract seeds of Trigonella foenum - graecum and quercetin drug on the liver tissues which had been poisoned and the best effect in the protection appeared at the group which was treated with the extract and quercetin together. From this study we can conclude that the Trigonella foenum - graecum organic extract and quercetin may reveal a protective role for the liver against carbon tetrachloride poisoning by maintaining the effectiveness of liver enzymes Alanine Transaminase, Aspartate Transaminase and Alkaline phosphatase and bilirubin level in the serum as well as by increasing the Glutathione level and falling the Malondialdehyde level in liver homogenized. Also we conclude that using Trigonella foenum - graecum organic extract and quercetin together led to double protection of the liver and efficiently as a result of the positive impact which resulted from using them together
