CONTEXT Measurement of blood haemoglobin concentration by pulse oximetry could be of value in determining when erythrocytes should be transfused during surgery, but the effect of infusion fluids on the results is unclear. OBJECTIVE To study the effect of crystalloid and colloid fluid on the accuracy (bias) and precision of pulse oximetry haemoglobin estimation to indicate the venous haemoglob...
AIMS To assess the accuracy and precision of measuring haemoglobin A(2) by high performance liquid chromatography (HPLC) in the presence and absence of sickle cell trait, with or without alpha thalassaemia trait. METHODS The haemoglobin A(2) percentage and the haemoglobin A(2) plus S percentages were determined by HPLC on 82 normal controls and 78 patients with sickle cell trait, respectively...
OBJECTIVE Our recent studies have shown that blood components, including haemoglobin and iron, contribute to hydrocephalus development and brain injury after intraventricular haemorrhage (IVH). The current study investigated the role of lipocalin 2 (LCN2), a protein involved in iron handling, in the ventricular dilation and neuroinflammation caused by brain injury in a mouse model of IVH. DES...
Background: This study investigated the protective effects of aqueous extracts of Anogeissus leiocarpus (DC) Guill & Perr (Combretaceae) and Terminalia avicennioides Guill & Perr (Combretaceae) root barks, as well as their 1:1 (w/w) mixture on liver redox and haematological parameters of diethylnitrosamine-treated rats. Methods: Rats were orally administered distilled water, diethylnitrosami...
The prevalence of nocturnal enuresis (wet at least two nights a week) was investigated in children, aged 8, who were being followed up as part of a prospective cohort study. There were 175 children with homozygous sickle cell disease, 106 with sickle cell haemoglobin C disease, and 150 controls with a normal haemoglobin genotype. In homozygous sickle cell disease, 48 boys (52%) and 31 girls (38...
Haemoglobin interference in the determination of bilirubin was compared in 7 different methods using the Jendrassik-Grof procedure, the Jendrassik-Grof-Nosslin modification, and the more recent procedures using nitrophenyldiazonium, 2,5-dichlorophenyldiazonium, 2,4-dichloraniline, and a direct reading method. To a variable degree, haemoglobin decreased the apparent absorption of the reaction pr...
