Endogenous bone marrow stem cell mobilization in rats: Its potential role in homing and repair of damaged inner ear

AbstractThe stem cells are widely used in the last few years in different fields of medicine, either by external transplantation or endogenous mobilization, most of these studies are still experimental on animals; few were tried on humans as in the spinal cord injury or myocardial infarction. As regards its use in the inner ear, stem cell transplantation was examined in many previous studies, while the mobilization idea is a new method to be experimented in inner ear hair cell regeneration.The aim of this work was to assess the use of GCSF to induce bone marrow SC mobilization to home and repair the damaged inner ear hair cells in rats after the damage had been inflicted by Amikacin injection.First we had to develop an animal model for damaged inner ear, so we used the well known ototoxic effect of Amikacin intra-tympanic injection till we reached complete loss of hearing function. And this can be assessed by DPOAEs. Now we have an animal model of damaged inner ear hair cells and mobilization of bone marrow SCs was induced by subcutaneous injection of G-CSF for 5days.Clinical assessment was done using DPOAEs before and after G-CSF injection also histological assessment of the inner ear was done before and after G-CSF by two methods H&E staining and Scanning Electron Microscopy.The results of histological examination of the specimens showed some promising changes that may be responsible for the improvement of hearing function in some rats that was detected by OAEs

EVALUATION OF APPLICATION OF INTERNATIONAL PROSTATE SYMPTOMS SCORE IN SUDANESE PATIENTS WITH BENIGN PROSTATIC HYPERPLASIA

Objectives: The purpose of the present study is to assess the reliability and validity of IPSS in pre- and treatment of Sudanese patients with BPH. Material and methods: In a descriptive prospective study, 350 Sudanese patients with LUTS attended the Urology department of Gezira Hospital for Renal Diseases and Surgery from September 2003 to April 2006. They were interviewed by urologists and answered the International Prostate Symptom Score (IPSS) questionnaire. Clinical work up was done for all only patients with benign hyperplasia were included in the analysis .Europeans guideline was adopted in the management and the out come was also subjected to IPSS evaluation. Results: The most common voiding symptoms was a weak stream (93% of subjects), followed by intermittency (57%) and hesitancy (54%). The most prevalence of storage symptoms was nocturia (87% of subjects), followed by frequency (73%) and urgency (64%). 64% of the study subjects   presented with severe IPSS, 33% with moderate IPSS, while only 3% of the patients presented with mild IPSS. Digital rectal examination (DRE) was done to all study subjects. There was no significant correlation between DRE and IPSS reported. The postoperative IPSS post treatment follow up was mild in 87%, moderate in 4% and sever in 9% of the patients.   Conclusion: Our study indicates that IPSS is informative and reproducible in assessment of patients with BPH. &nbsp

Copper(II)-oxaloyldihydrazone complexes: Physico-chemical studies: Energy band gap and inhibition evaluation of free oxaloyldihydrazones toward the corrosion of copper metal in acidic medium

AbstractA series of oxaloyldihydrazone ligands were prepared essentially by the conventional condensation reaction between oxaloyldihydrazide and different aldehydes e.g., salicylaldehyde, 2-hydroxy-1-naphthaldehyde, 2-hydroxyacetophenone and 2-methoxybenzaldehyde in 1:2M ratio. The synthesized compounds were purified to give bis(salicylaldehyde)oxaloyldihydrazone (L1), bis(2-hydroxy-1-naphthaldehyde)oxaloyldihydrazone (L2), bis(2-hydroxyacetophenone)oxaloyldihydrazone (L3) and bis(2-methoxybenzaldehyde)oxaloyldihydrazone (L4). All the oxaloyldihydrazones (L1–L4) and their relevant solid copper(II) complexes have been isolated and characterized by various physicochemical techniques. The identity of the synthesized compounds has been ascertained on the basis of elemental analyses, spectral (UV–Vis, IR, ESR, mass, 1H NMR), magnetism and thermal (TG) measurements. The dihydrazones coordinate to the metal center forming binuclear complexes. Upon chelation, the metal center can form a trigonal distorted octahedral structure with L1 and pseudo tetrahedral configuration with L2 & L3 & L4. The optical band gap energy for all compounds underlies the range of semiconductor materials. The investigated ligands were assayed for their corrosion inhibitive and adsorptive properties on copper surface in 1M HCl solution using weight loss technique. The results pointed out that, the ligands have a plausible inhibition toward the corrosion of copper specimen. The adsorption reaction on copper surface was found to be spontaneous first order and agreed with physical adsorption mechanism. The adsorption data fitted well to Freundlich, Langmuir and Frumkin adsorption isotherms

Quality of life of Sudanese Patients with Benigan Prostatic Hyperplasia. The Oblivious Problem

Background: Although the IPSS and QOL index are universally used, they can only quantify the severity of lower urinary tract symptoms suggestive of benign prostate hyperplasia (BPH) and evaluate treatment efficacy, but cannot fully reflect the overall quality of life. Moreover, because QOL scale depends on the culture background, it is necessary to develop a Sudanese version of the scale. Objective: To evaluate the impact of BPH on the quality of life by assessing the physical, mental and stress states among patients of BPH. Methodology: This study was conducted on 424 patients with BPH in Gezira Hospital for Renal Disease and Surgery (GHRDS), Sudan. The study was cross-sectional, prospective small-scale hospital based study using simple random sampling technique. The subjects were limited to the Sudanese patients, who could hear and answer the questions of the questionnaire independently and that was done for accuracy and privacy. Taking the patient's educational level into account, all items were expressed in spoken language. The data collection tool was a questionnaire which was modified to twelve items from the BPH Quality of Life Index. Results: The majority 386 patients, 91% were physically fit. The pattern of urination was bothering to their daily life of around 320 patients/75.5%, 225 patients/53.1% of patients were worried about the outcome of the disease, 259 patients/61.1% were not concerned of having prostate cancer and 332 patients/78.2% were satisfied with their sleep. The sexual life had been affected in 201 patients/47.4%. The physical state was assessed by the ability of the patient to pray Friday Jomaa at the mosque which was 85.8% and also by attending important Sudanese obliging social activities like condolence which was (91.9%) of the patients. Conclusion: The impact of BPH on quality of life was obviously significant in the three domains; physical, mental and stress state among patients of BPH in GHRD&S.There should be a validated scale for the BPH Quality of Life Index addressing the traditional strata for Sudanese patients.           &nbsp
