يهدف البحث إلى تحضير سلسلة من معقدات العناصر الانتقالية ثنائية التكافؤ(المنغنيز, الكوبلت, النيكل, الخارصين والكادميوم) مع المركب الجديد(KL) والمشتق من تفاعل ثنائي كبريتيد الكاربون و المركب الوسطي (HD). شخصت المعقدات ذات الصيغة العامة[M(L)2] بواسطة طيف الرنين النووي المغناطيسي البروتوني والكربوني للمركب الجديد وقياسات الأشعة تحت الحمراء والطيف الإلكتروني ودرجات الانصهار و التوصيلية المولارية و تحليل العناصر .C. H .N S والنسبة المئوية للفلز M في المعقدات والحساسية المغناطيسية والدراسة الحرارية للمركب (KL) وبعض المعقدات. استنادا إلى النتائج المعطاه للدراسات المذكورة فقد تم اقتراح الشكل رباعي السطوح للمعقدات المحضرة من خلال ارتباط ذرات الكبريت لمجموعة الثايول في المركب (KL) مع الأيونات الفلزية وكذلك تمت دراسة الفاعلية الحيوية للمركب المشتق ومعقداته ضد نوعين من البكتريا السالبة (Escherichia coli) والموجبة (Staphylococcus aurous) بتقنية الانتشار كما تم استخدام المركب المحضر (KL) كمثبط لتأكل سبيكة الفا-براص في محلول ملحي لكلورید الصودیوم بتركیز 0.6 مول. دسم-3 لثلاث قيم من الدوال الحامضية (2،4, 7) في ثلاث درجات حرارية مختلفة تراوحت (288-308) مطلقة وبتركيز مقداره 3-10مول.دسم3- لمركب (KL) باستعمال تقنية المجھاد الساكن وتم التعبير عن النتائج من خلال تسجيل قیم تيار التآكل (icorr) حيث اوضحت النتائج ان المركب قام بعمل التثبيط لتأكل سبيكة الفا- براص عند قيمتي الدالة الحامضية 7,4 وكما تم حساب كفاءة التأكل P% اضافة الى الثوابت الثرموديناميكية لعملية التثبيط
This work studies the role of serum apelin-36 and Glutathione S-transferases (GST) activity in association with the hormonal, metabolic profiles and their link to the risk of cardiovascular disease (CVD) in healthy and patients' ladies with polycystic ovary syndrome (PCOS). A total of fifty-four (PCOS) patients and thirty-one healthy woman as a control have been studied. The PCOS patients were subdivided on the basis of body-mass-index (BMI), into 2-subgroups (the first group was obese-PCOS with BMI ≥ 30 and the second group was non-obese PCOS MBI<30).
