Abstract: This thesis contains three chapters represents, the first chapter introduction and interested in studying the chemistry of schiff base and derivatives of formazan, their complexes in terms of their characteristics, importance and synthesis.The second chapter is interested in describing the chemicals and procedures used in the synthesis of the required compounds, and the study of physical measurements, synthesis methods of compounds and evaluation as well as the biological activity.In this research, four new derivatives of formazan (L3, L4, L5 - 4d), which synthesized from the reaction of Diazonium salt amine with suitable Schiff base (L1, L2 - 2d). The Schiff base can product of different primary amines with several aromatic aldehyde and synthesized both of the (Schiff bases, formazans) suitable complexes.The third chapter Results and Discussion, identified synthesized formazan derivatives as well as Schiff bases prefix and its complexes by appropriate spectral methods including of infrared spectroscopy (FT - IR) for all compounds, Nuclear Magnetic Resonance spectrum (1H - NMR) for all compounds Microanalysis (CHNS) for the majority of compounds as well as Mass spectra. For all complexes were recording certain physical properties, such as melting point (m.p.). Monitoring progress of the chemical reaction by using thin chromatography layer (TLC). We synthesis eight complexes (three from Schiff bases and five from formazan derivatives) were complexes with ions (Co, Ni, Cd), then measuring the molar conductivity of complexes. Then study the biological effectiveness for some compounds have been chosen complexes Schiff bases, as well as formazan complexes to determine the effect of active groups in these compounds to evaluate the efficiency ofXIthe compounds against different type of bacteria.The research also includes a test of biological effectiveness of the prepared ligands and their metallic complexes, where we study response inhibitory to the three types of bacteria, a gram positive type of bacteria (Staphylococcus aureuse) and gram negative type of the bacteria (Escherichia Coli and salmonella species) and compared with the standard inhibitor (Cipro).The biological effectiveness swohs positive results as it was noted The ligand L1, L2, L3, L4, L5 and Schiff base 4d Showed lower efficiency than the standard inhibitor trend three types of bacteria. The prepared complexes from ligands appeared high effective than the effectiveness of the ligands itself The formazan (L3, L4, L5 dna 2d) appeared high effective than the effectiveness of the prepared Schiff base

Abstract: Atrial fibrillation (AF) is the most common cardiac arrhythmia in the general population, and a major cause of morbidity and mortality. Lifetime risk for development of AF has been estimated to 1 in 4 in individuals aged 40 years or more.The present study is designed to determine the levels of oxidative stress by measuring lipid peroxidation product (malondialdehyde MDA), antioxidant state by measuring some antioxidants such as (ceruloplasmin Cp, Transferrin Tf, albumin Alb ,uric acid Ua) ,in addition to lipid profile (cholesterol TC, triglyceride TG, high density lipoprotein cholesterol HDL - C, low density lipoprotein cholesterol LDL - C and very low density lipoprotein cholesterol VLDL - C) in atrial fibrillation patients .The study included (150) subjects; (75) normal subjects (control) and (75) patients with atrial fibrillation. The patients are divided into two groups according to the age : (39) elderly patients [the age range (60 - 80) years] and (36) others patients [the age range (20 - 59) years], also patients are divided in to two groups according to the age with one or more risk factor (Hypertention (HTN), Ischemic Heart Disease(IHD), Heart Hailure (HF)) : elderly which included (18) patients (lone AF) , (21) patients (AF with HTN, IHD, HF) and others which included (17) patients (lone AF), (19) patients (AF with HTN, IHD, HF).The normal subjects (control) also divided into two groups according to the age : elderly [the age range (60 - 80) years] and others [the age range (20 - 59) years] .According to age, the results shown significant increase in the concentration of serum (MDA, Cp, uric acid, TC, TG, VLDL - C, LDL - C ) in elderly and other groups in comparison with their control groups (p≤0.05). It was found significant increase in the concentration of serum MDA in elderly group in comparison with other group, also it was found significant increase in the concentration of serum uric acid in control elderly group in comparison withXIVcontrol other group (p≤0.05). The results also showed non significant differences in the concentration of serum (Cp, uric acid, TC,TG, LDL - C, VLDL - C) between elderly and other groups. It was also found non significant differences in the concentration of serum ( Cp, TC, TG, LDL - C, VLDL - C) between control elderly and control other groups (p≤0.05). While serum Alb , serum Tf and serum HDL - C concentrations show a significant decrease in elderly and other groups in comparison with their control groups (p≤0.05). The results showed significant decrease in the concentration of serum HDL - C in control elderly group in comparison with control other group. Also there were no significant differences in the concentration of serum Alb serum Tf and serum HDL - C between elderly and others groups (p≤0.05).According to the age with one or more risk factor (HTN, IHD, HF) the results show a significant increase in the concentration of serum (MDA, Cp , uric acid, TC, TG, VLDL - C , LDL - C ) in elderly and other groups in comparison with their control groups (p≤0.05). It was found a significant increase in the concentration of serum MDA in the groups AF and AF with HTN, IHD, HF ( in elderly groups) in comparison with groups AF and AF with HTN, IHD, HF (in other groups) respectively (p≤0.05). It was also found a significant increase in the concentration of serum uric acid in control elderly groups in comparison with control other groups , also there were no significant differences in the concentration of serum (CP ,TC , TG ,VLDL - C, LDL - C) between elderly and other groups (p≤0.05). serum Alb ,serum Tf and serum HDL - C show a significant decrease in elderly and other groups in comparison with their control groups, also there was significant decrease in the concentration of serum HDL - C in control elderly groups in comparison with control other groups (p≤0.05). It was also found non significant differences in the concentration of serum Alb and serum Tf between elderly and other groups (p≤0.05).
