The formazans compounds[4a - 4h] were prepared by reacting diazonium salts amines[3a - 3c] with the appropriate Schiff bases[2a - 2h].Schiff bases themselves are synthesized by the condensation of different primary amines with various aromaticaldehydes. The thiazolidinones derivatives[5c,5e,5i,5j,5k] are synthesized by condensing thioglycolic acid with various Schiff bases[2a - 2h]. All the structures prepared [2a - 2k] , [4a - 4h] and [2c, 2e ,2i ,2j , 2k] were shown in scheme(1), and characterized on the basis of the spectral data : IR, Mass, 1H and 13C NMR.

The IR spectra show an important absorption band at (1558 - 1689)cm - 1 attributed to azomethine (C=N) for Schiff bases, the IR spectra showed important absorption band at (1681 - 1597 )cm - 1 attributed to azomethine (C=N) and (1465 - 1558) cm - 1 to ( - N=N - ) for formazans derivatives. Also, the IR spectra show an important absorption band at (1689 - 1658)cm - 1 attributed to the thiazolidinones ring . The 1H - NMR spectra of formazans show aromatic protons at the range (7.07 - 8.49 )ppm and pyridyl protons as downfield signal at (8.22 - 9.15 ) hydrazide signal at 11 ppm. The 1H - NMR of thiazolidinones exhibit new signals attributed to - CH2 and - CH of thiazolidnones ring at δ (4.52 - 4.71) and (5.70 - 5.81 ) ppm, respectively .13C - NMR spectra of formazans exhibit that the a signal at 156 - 168 ppm (amide carbonyl) , thiazolidinones show a signal at (207.35 - 208 .60) ppm attributed to the C=O ring thiazolidinones.The mass spectra of the formazans compounds [4d ,4e, 4g , 4h] show a molecular ion peak.

دراسة مقارنة لفرط الاكسدة ووظائف الكبد في النساء ذوات تضخم الغدة الدرقية قبل وبعد عملية الاستئصال Compartive Study for Oxidative Stress and Liver Functions in Women with Euthyroid Goiter before and after Thyroidectomy

المستخلص: Multinodular goiter defined as the palpation of multiple distinct nodules in the enlarged thyroid gland and it is one of the commonest thyroid diseases encountered in the practice of surgery. Treatment modalities are mainly antithyroid drugs and surgery. The most common surgery being performed for multinodular goitre is subtotal thyroidectomy for the reasons that it is comparatively easier to perform, less time consuming and has a lesser complication rate especially of damage to recurrent laryngeal nerve andparathyroids. Subtotal thyroidectomy involves removal of majority of the diseased thyroid tissue along with the isthmus leaving behind a remnant of roughly 4 - 8 grams on each side.This study was accomplished for evaluation the effect of thyroidectomy on thyroid hormones levels (T3, T4 and TSH) ,serum oxidant - antioxidants status( malondialdehyde (MDA) , ceruloplasmin (Cp), transferrin (Tf ) and albumin (Alb)) , also liver function tests (aspartate amino transferase enzyme (AST), alanine amino transferase enzyme (ALT), alkaline phosphatase (ALP) and total bilirubin (BIL)). Blood samples were obtained from (100) patients with euthyroid goiter, as well as (50) healthy subjects as a control group.The comparison is based on three variables : general comparison ]Group A (Control) : - Included fifty health subjects aged (15 - 60) years.

دراسة مستويات مصل الهوموسيستين وعلاقته مع بعض انزيمات القلب في المرضى الذين يعانون من احتشاء عضلة القلب في محافظة ذي قار - العراق Study of Serum Homocysteine levels and Its Correlation with Some Cardiac Enzymes in Patients with Myocardial Infarction In Thi - Qar Province/Iraq

المستخلص: Myocardial infarction (MI) or acute myocardial infarction (AMI) is the medical term for an event commonly known as heart attack. An MI occurs when blood stops flowing properly to a part of the heart, and the heart muscle is injured because it is not receiving enough oxygen. Biochemical tests are restricted to monitoring cardiac enzymes activities. Therefore, introducing homocysteine test in hospitals for MI patients may provide a clearer picture on the patient condition and help in the disease management.The study was conducted during the period from October 2015 till August 2016. Sixty - three of the people who have a history of injury in the acute myocardial infarction are studied. The diagnosis is based on the clinical presentation and confirmed by ECG, and cardiac enzyme. Forty - eight of persons as healthy volunteers were selected as a control group.The results indicated the following : The proportion of patients male (57%) and females (43%), smokers (49%) and non - smokers (51%), most of them are females. The results also showed that (32%) live in cities, compared to (68%) live in rural areas, and patients Serum homocysteine was significantly higher in MI patients compared to the control group. Homocysteine levels were higher in smokers(p = 0.0001). and unemployed individuals(p < 0.0001)., as well as in individuals with family history of MI or CAD(p < 0.0001). High hypertensive, diabetic and obese individuals had also higher levels of homocysteine . Based on the results of this study suggested measuring the amino acid Homocysteine levels of security as one of the effective ways to diagnose patients with myocardial infarction in hospitals
