New Metal Complexes Derived from Schiff-Base Ligand: Synthesis Structural Characterisation, Thermal Properties and Biological Evaluation
...Show More Authors

New Schiff-base ligand and metal complexes with Cr (Ш), Mn (II), Fe (II), Co (II), Ni (II) and Cu (II) ions are reported. Ligand was prepared in two-step reaction. The reaction of 2-hydroxy-5-methylisophthalaldehyde with 3-Amino-1-propanol resulted in the isolation of precursor (3, 3'-((1E, 1'E)-(propane-1, 3-diylbis (azanylylidene)) bis (methanylylidene)) bis (2-hydroxy-5-methylbenzaldehyde)). The reaction of precursor with 4-Aminoantipyrine gave the required ligand;(4, 4'-(((1E, 1'E)-(((1E, 1'E)(propane-1, 3-diylbis (azanylylidene)) bis (methanyl ylidene)) bis (2-hydroxy-5-methyl-3, 1-phenylene)) bis (methanylylidene)) bis (azanyl ylid ene)) bis (1, 5-dimethyl-2-phenyl-1, 2-dihydro-3H-pyrazol-3-one)) H 2 L. The reaction of this ligand with the appropriate metal ions gave metal complexes of the formulae [M 2 (L)(H 2 O) 2 Cl 2]. Cl 2, M= Cr (Ш),[M 2 (L) Cl 2 (H 2 O) 2], M= Mn (II), Fe (II),[M 2 (L)] Cl 2. H 2 O, M= Co (II), Ni (II),[M 2 (L) Cl 2] H 2 O, M= Cu (II). A range of techniques were used to confirm the entity of ligand and their complexes. The formation of ligand and mode of complexation and geometrical structure of complexes were verified using FTIR, electronic spectra, NMR, ESMS, magnetic susceptibility, micro-elemental analysis, metal content, chloride content and conductance. The analytical and spectroscopic data indicated the formation of four and six-coordinate for complexes. Biological evaluation of ligand and complexes against gram-positive bacteria (G+), Bacillus stubtili, Staphylococcus aureus, and gram-negative bacteria (G−), Escherichia coli and Pseudomonas aeruginosa and compared with antibiotic drug (Cefotaxime) and two types of

Clinical and Sonographic Changes of Parotid Gland in Patients with Type I and Type II Diabetes Mellitus and Its Effect on Physical Properties of Saliva
...Show More Authors

Background: Sialosis described as a specific consequence of diabetes. In diabetic sialosis, the increased volume of the glands is due to the infiltration of adipose in the parenchyma. The B-scan ultrasonography is a generally accepted tool for determining parotid gland enlargement. Oral health is, to a greater extent, dependent on quality and quantity of saliva, both of which may be altered in diabetics. This study was established to detect the enlargement of parotid gland in diabetic patient and study the changes in physical properties of saliva and its relation with the salivary gland enlargement. Subjects, Materials and Methods: A cross-sectional study with highly specified criteria with ages ranged (20-65) years, male and female subject

Evaluation of flexural strength and degree of conversion of temporary crown materials at different aging periods in artificial saliva
...Show More Authors

Objective: Evaluate the effects of different storage periods on flexural strength (FS) and degree of conversion (DC) of Bis-Acryl composite and Urethane dimethacrylate provisional restorative materials. Material and Methods: A total of 60 specimens were prepared from four temporary crown materials commercially available and assigned to four tested groups (n = 15 for each group): Prevision Temp, B&E CROWN, Primma Art, and Charm Temp groups. The specimens were stored in artificial saliva, and the FS was tested after 24 h, 7 d, and 14 d. A standard three-point bending test was conducted using a universal testing machine. Additionally, the DC was determined using a Fourier transform infrared spectroscopy (FTIR) device. The data were analyzed st

Evaluation of Fludarabine, and granulocyte colony stimulating factor in treatment of efractory/Relapsed Acute Leukemias in adult Iraqi patients
...Show More Authors

Background: Refractory/relapsed acute leukemia has always been a challenging problem for hematologist. Over the past decade emphasis has been made in the development of regimens containing fludarabine, combined with cytosine arabinoside for the treatment of refractory/relapsed acute leukemias. The aim of this study is to evaluate the efficacy and toxicity of the combination of fludarabine, high dose cytarabine, and granulocyte colony stimulating factor in refractory relapsed cases of acute leukaemia,
Methods: a prospective study is being conducted at the national center of hematology and hematology unit /Baghdad teaching hospital from July 2008 to July 2010.Twenty Patients with refractory/relapsed acute leukemia were treated with flud

Histological evaluation of local application of collagen I and /or vascular endothelial growth factor (An experimental study in rats)
...Show More Authors

Background: The study was designed to evaluate the effect of local application of exogenous VEGF/collagen I separately and as a combination in socket healing. Sixty male Albino Wistar rats were subjected for a surgical tooth extraction of upper 1st molar of both sides (right side was considered as experimental site, while left be the control one, treated with 1µL of normal saline). The rats were scarified at 3, 7, 14, 28 days post extraction. Socket healing was histologically examined with immunohistochemistochemical localization of ALP&FGF2. Materials and Method: Sixty male Albino Wistar rats were subjected for a surgical tooth extraction of upper 1stmolar of both sides (right side was considered as experimental site, while left be the

Evaluation of interleukin-9 serum level and gene polymorphism in a sample of Iraqi type 2 diabetic mellitus patients
...Show More Authors

Background: Diabetic mellitus (DM) is a collection of metabolic disorder identified by hyperglycemia. The heterogeneous etiology includes defects either in insulin secretion, or in insulin action, or the both. In addition to the distraction in carbohydrate, fat and protein metabolism. Inflammatory reaction that caused by many pro-inflammatory cytokines play a central role in the pathogenicity of T2DM, these cytokines can enhance insulin resistance which led to impaired glucose homeostasis. Subjects: The study included 75 patients (38 males and 37 females) suffering from T2DM with age mean ± SE 52.30 ± 1.60, and 70 individuals as healthy controls (35 males and 35 females) with age mean ± SE 48.88 ± 0.64.
