Antistreptolysin O (ASO) titers were determined on 117 human sera with rabbit, human, and sheep red blood cells (RBC) as the indicator system in the ASO tube test. The titers of 65% of the sera were one dilution step higher when a 5% suspension of sheep RBC was used instead of a 5% suspension of rabbit RBC. Titers were one dilution step higher in 42.7% of the sera when a 5% suspension of human ...

Patients with Polythemia vera (PV) have a high incidence of thrombosis (25-75 %). Vascular complications are responsible of retinopathy, renal failure and coronary disease in diabetes mellitus (DM). Retinal Vascular Vein Occlusion (RVO) is a cause of blindness. To evaluate is red blood cell (RBC) abnormalities may be one vascular risk in these disease we studied RBC adhesion to endothelial cell...

The aim of this study was to highlight the contribution bone scintigraphy in assessment extension osteophilic cancers Senegal. This a retrospective study, with descriptive and analytical purpose, carried out over period four (04) years between January 01, 2018 December 31, 2021. It focused on files patients who underwent for an cancer during period. According prostate by far most representative...

Horse blood has a higher tendency to form red blood cell (RBC) aggregates compared with human blood, with this enhanced aggregation previously attributed to differences in plasma factors. Our results confirm this observation and further indicate that washed horse RBC also have a significantly higher aggregation tendency in dextran 70 solutions (i.e., horse RBC have a higher "aggregability"). In...

Aim This study was aimed to explore the effects of carboxyhemoglobin on reperfusion injury in hemorrhagic shock, as well as its action time and related mechanisms. Results CO-RBC group showed milder oxidative injury than O2-RBC group. CO reperfusion did not show advantages in functions of kidney and lung during resuscitation. The level of Bax was decreased in CO-RBC group, especially in early...

Introduction: In this study the automatic separation of oral and salivary gland activity and spontaneous secretion by means of factor analysis for quantitative salivary gland scintigraphy is introduced. Methods: After intravenous administration of 99mTc sodium pertechnetate, dynamic scintigraphy was performed. 20 minutes after tracer application 2 ml of lemon juice was delivered to stimulate t...

haemoplasmas contain eperythrozoon and haemobartonella species, which are widespread causes of animal and human infections. these obligatory cell parasites were previously known as hemobartonella; now hemotropic mycoplasmas. these bacteria are identified by the lack of cell wall and their small genome. the usual diameter is between 0.3 and1μm. mycoplasmasarepolymorphic and seen in circular or b...

SCOPE We modeled red blood cell (RBC)-folate response to supplementation and developed personalized folate supplementation concepts. METHODS AND RESULTS The changes of RBC-folate were modeled in a time- (4 or 8 weeks) and dose- (400 or 800 μg d-1 folate) dependent manner. Post-supplementation RBC-folate levels were predicted from folate-loading capacities (= measured RBC-folate - [baseline RB...

The purpose of this study was to investigate red blood cell (RBC) behavior during an increase in local cerebral blood flow (LCBF). We measured changes in RBC behavior by using laser-Doppler flowmetry (LDF) in alpha-chloralose-anesthetized rats. An increase in LCBF was carried out by approximately 2.5 and 4.0% CO(2) inhalation and activation of the somatosensory cortex. The activation of the cor...
