Abdalla Fetal hemoglobin (HbF) is the main hemoglobin throughout the fetal life and at birth, accounting for approximately 80% of total hemoglobin in newborn. HbF, when elevated during sickle cell disease (SCD), cause reduction of different crises associated with SCD. Elevation of HbF is achieved by hydroxyurea (HU) therapy as a tool to control SCD. This study was conducted in the period between May 2009 to December 2009 to determine the levels of HbF in SCD pediatric patients treated with hydroxyurea (HU) therapy and evaluate its effects on elevation of HbF which lead to the reduction of SCD crises. Ninety one Sudanese SCD pediatric patients with mean age of (6.0 years � 2.9), who were referred to Jafaar Ibnouf hospital in Khartoum city, were included in this study. Sixty one of the patients, designated group T, had been treated with 22 mg /Kg/ day of HU for seven months; and thirty patients had been treated with conventional treatment were used as control designated group C. Two and half ml blood sample was collected from each participant in Ethylene Diamine Tetra Acetic Acid (EDTA) container. HbF level was determined by using the denaturation method. The results showed that the mean of HbF levels in group T was 8.00 � 02.59 while the mean of HbF level in the control group (C) which was 0.8 � 0.2. article Sun, 01 Jan 2012 00:00:00 GMT https://repository.sustech.edu/handle/123456789/16696 2012-01-01T00:00:00Z https://repository.sustech.edu/handle/123456789/16698 Molecular Characterization and Sensitivity Pattern of Pseudomona aeruginosa Among Patients With Different Diseases in Khartoum, Sudan alneel,Yousif Fadl alla Hamd; Maha DafaAlla Abd elrazig The aim of this study was to determine the presence of the genes implicated in resistance to agents used for chemotherapy of infectious diseases caused by Pseudomonas aeruginosa. Seventy four P. aeruginosa strains were isolated from patients hospitalised in the Khartoum Teaching Hospital, Sudan. The strains were isolated in the period from February to June 2011 and serotyped studied at the research laboratory in Sudan University of Science and Theology. The isolates were recovered from patients with multiple types of infections, mostly respiratory tract, urinary tract and postoperative wound infection. Direct PCR technique was used to identify the genes implicated in antimicrobial resistance mechanisms. DNA extraction was skipped and the bacterial cell wall was denaturized in the first step of the reaction. The presence of IMP family genes, in the tested isolates of P. aeruginosa was identified, namely IMP-7 and IMP-10. This was the first report of the presence of IMP-7 and IMP-10 type genes in P. aeruginosa isolates in Khartoum State, Sudan. article Sun, 01 Jan 2012 00:00:00 GMT https://repository.sustech.edu/handle/123456789/16698 2012-01-01T00:00:00Z https://repository.sustech.edu/handle/123456789/16695 CR-Sub Manifolds of the Six Dimensional Sphere Zomam,Hanan Omer; M. A. Bashir In this paper a proper CR-submanifolds of the 6-dimensional sphere was considered, S6. some characterization theorems of their submanifolds were provided. In particular, 4- dimensional CR-submanifolds were introduced and their theorems were illustrated with examples. article Sun, 01 Jan 2012 00:00:00 GMT https://repository.sustech.edu/handle/123456789/16695 2012-01-01T00:00:00Z
