Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease of central nervous system with complex etiopathogenesis that impacts young adults (Lee et al., 2015), and MS impacts younger and middle aged character and leads to a range of disabilities that can alter their daily routines (Yara et al, 2010). Although, the exact cause of MS is still undetermined, the disease is mediated by adaptive immunity through the infiltration of T cells into the central nervous system (Bjelobaba et al, 2017). MS causes the Focal neurological symptomsand biochemical changes in the molecular level and the variation of neural cells such as loss or alteration of sensation, motor function, visible signs such as blurred vision or transient blindness, disturbance of conjugate eye movements, bladder and bowel dysfunction and cognitive impairment (Induruwa et al, 2012 and Jafarzadeh et al, 2014). Autoimmune diseases (ADs) are chronic conditions initiated by way of the loss of immunological tolerance to self-antigens (TodorovicDilas et al, 2011). It is a heterogeneous group of disorders in which more than one modification in the immune system can be specific to a particular tissue or organ or might also be systemic, non-specific, involving multiple tissues or organs (Ray et al, 2012). One possible cause behind this is a lack of understanding of pathogenic mechanisms driving progressive multiple sclerosis. Due to the indolent nature of symptom progression, current disease criteria used to signify the course of disease (Lublin et al, 2014) indicate diagnosis is generally retrospective and based totally on history of gradual worsening. Clearly, diagnosis is primary based on clinical judgment, as there is no fully reliable diagnostic test (Ontaneda et al, 2015). In latest years, the elements involved in the etiology of the disease have also included oxidative stress (OS), which is described as an imbalance between the generation of reactive oxygen species (ROS) and the mechanisms that are responsible for their elimination, andthe imbalance between OS agents and antioxidants leads to OS activating the inflammatory process (Phaniendra et al, 2015). In the absence of enough antioxidant defenses, ROS can reason oxidative damage to macromolecules resulting in oxidation of lipids, proteins and deoxyribonucleic acid (DNA) (Griffiths, 2002). Some reseach report that ROS play a main role in myelin phagocytosis (Ghabaee et al, 2010 and Tasset et al, 2012). The inflammatory response gives rise to the manufacturing of both ROS and Reactive Biochem. Cell. Arch.

Aim of study The aim of this study focuses on determination 8-H2-dG, MDA and PON1 in multiple sclerosis disease and finds the relationship between newly marker 8-H-2-dG with MDA and PON1. MATERIALS AND METHODS Subjects This study was performed on 25 female patients with age (25-35) years who diagnosed by physicians as a multiple sclerosis in Misan governorate. The patients compared with 25 apparently healthful in the identic rangel of age. In this study sample was collected five mL of venous bloods, placed in to plain tubes until coagulation was performed. Serum was separated from blood cells by centrifugation 4000 r.p.m. Assay method Determination of serum of 8-H-2-dG This assay that can be used for quantification of 8- H-2-dG in urine, cell culture, plasma and other sample matrices. The ELISA utilize an 8-H-2-dG coated plate and HRP- conjugated antibody or detection which allows for any assay range of 0.94-60 ng/mL, with sensitivity of 0.59 ng/mL. Determination of MDA The concentration of MDA,which is the consequence of lipid peroxidation and a marker of oxidative stress, was measured using thiobarbiturc acid. Determination of PON1 The quantitive sandwich enzyme immunoassay (ELISA) technique was employed for determination of PON1.
The synthesis, characterization and liquid crystalline properties of N4,N40 -bis((1 H-benzo[d]imidazol-2- yl)methyl)-3,30 -dimethyl-[1,10 -biphenyl]-4,40 -diamine and of their corresponding Mn(II), Fe(II), Ni (II), Cu(II), and Zn(II) complexes are described. The ligand and complexes have been characterized by elemental analysis, magnetic susceptibility measurements (meff), conductometric measurements and Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (1 H NMR), (13C-NMR) and UV–Vis spectroscopy. Spectral investigations suggested octahedral coordination geometrical arrangement for M(II) complexes.

Aldehyde group [2] was obtained from the reaction of compound [1] with pocl3 in presence of DMF and CHCl3 .After that shiff bases have been synthesized from the reaction of compound [2] with different aromatic amine to give new shiff bases [3- 5]. These new shiff bases have been reduced to their corresponding amine [6-8] by means of sodium borohydride. Then reaction of shiff bases [3-5] with phenyl isocyanate gives 3-cyclic lactam derivatives [9-11]. 3-cyclic Oxazepine derivatives [12-14] were obtained by reaction of shiff bases [3-5] with succinic anhydride.

The structural feature were confirmed on the basis of their elemental analysis, metal content, molar conductance, magnetic measurement, FTIR, 1 HNMR and UV-Vis spectra studies. The isolated complexes were found to have a mole ratio (1:2) (metal:ligand) stoichiometry with the general formula [Ln(MBT)2]Cl (Ln(???) = La, Ce, Pr, Nd, Sm, Eu and Gd). The chelates were found to have octahedral structures. The FTIR spectra shows that the ligand (MBT) is coordinated to lanthanide ions as a N, N, O-tridentate anion via benzimidazole nitrogen, azo nitrogen and oxygen of hydroxyl after deprotonation. Com

A new methodology was applied to the synthesis of new imidazolones and oxyazepine derivatives containing imidazo thiazole fused rings. Starting with 5-(4-bromo phenyl) imidazo (2, 1-b) thiazole, which was synthesized using the standard procedure, the Carbaldehyed group was introduced at position 6 of 5-(4-bromo phenyl) imidazo (2, 1-b) thiazole. Then, this 6-carbaldehyed derivative was condensed with different substituted aromatic amines to afford new Schiff bases. The latter were cyclized into new oxazepine and imidazolone derivatives by using phthalic anhydride and glycine, respectively. These new derivatives were characterized by using FT-IR, 1HHNMR, and 13CNMR spectra, as well as examined (evaluated) for anti-bacterial and anti-fungal a
