HEMOGLOBIN OETSTALS OP BODENTS' BLOOD 181 On the Haemoglobin Crystals of Rodents' Blood

چکیده
THE crystals of haemoglobin since their first discovery have been described by various observers as occurring in̂ no less than five out of the six crystallographic .systems. Subsequent investigators have reduced this number: to two, namely, the rhombic system, in which the haemoglobin from.the blood of most animals crystallises; and the hexagonal system,:in which that from the blood of certain rodents is said to crystallise. This research was undertaken at Professor Lankester's suggestion, in order, first, to ascertain whether these six-sided crystals really belonged to the hexagonal system ; and, secondly^. to find, if possible, an explanation of the difference of crystalline form that haemoglobin presents in different animals, while in its other chief properties haemoglobin is universally the same. It will be convenient to take the Bubject under the following

The Comparison of Acetic Acid and Strontium Chloride Procedures for Extraction of Hemin
Abstract Background and objectives: Hemin is a porphyrin compound derived from hemoglobin, the precursor of other porphyrin hemoglobin derivatives and the raw material of Hematin. Since hemin is widely used in medicine, we decided primarily to synthesize this substance in Laboratory and to determine the best way of hemin extraction from untransfused and expired blood units. Materials and Method...
متن کاملA comparison of post-op haemoglobin levels and allogeneic blood transfusion rates following total knee arthroplasty without drainage or with reinfusion drains.
The effects of re-infusion drains on the rate of allogeneic blood transfusion and post-op haemoglobin levels in Total Knee Arthroplasty were examined. A group of 22 patients undergoing primary Total Knee Arthroplasty using a CBCII Constavac Stryker re-infusion drainage system were compared with a group of 30 patients, matched for age, sex and type of prosthesis but without any drain usage. The ...
متن کاملA New Approach Based on Erythrocyte Indices to Exclude Normal Populations from Chromatography Based Thalassemia Screening Programs with Very High Fidelity
Background: Screening and counselling is the most effective way to prevent the birth of children with thalassemia major. An accurate and relatively less time-consuming protocol is necessary to screen large populations. Separating iron deficiency anaemia from thalassemia trait based on blood cell parameters has been used by hematologists for many years. We aimed to design a new approach to scree...
متن کاملVariation in blood count parameters of children aged 5 to 11 years in Abidjan, Côte d\'Ivoire
Background: In Côte d’Ivoire, as in most developing countries, the reference values of hematological indices currently in use come from data collected from populations living in industrialized countries. The aim of this study was to determine variations in the childchr('39')s blood count in Cote dchr('39')Ivoire. Materials and Methods: This descriptive cross-sectional study has focused on 310 ...
متن کاملPurification, crystallization, preliminary X-ray diffraction and molecular-replacement studies of great cormorant (Phalacrocorax carbo) haemoglobin
Haemoglobin is the iron-containing oxygen-transport metalloprotein that is present in the red blood cells of all vertebrates. In recent decades, there has been substantial interest in attempting to understand the structural basis and functional diversity of avian haemoglobins. Towards this end, purification, crystallization, preliminary X-ray diffraction and molecular-replacement studies have b...
