Clinical Hemorheology and Microcirculation, a peer-reviewed international scientific journal, serves as an aid to understanding the flow properties of blood and the relationship to normal and abnormal physiology. The rapidly expanding science of hemorheology concerns blood, its components and the blood vessels with which blood interacts. It includes perihemorheology, i.e., the rheology of fluid and structures in the perivascular and interstitial spaces as well as the lymphatic system. The clinical aspects include pathogenesis, symptomatology and diagnostic methods, and the fields of prophylaxis and therapy in all branches of medicine and surgery, pharmacology and drug research.
The endeavour of the Editors-in-Chief and publishers of
Clinical Hemorheology and Microcirculation is to bring together contributions from those working in various fields related to blood flow all over the world. The editors of
Clinical Hemorheology and Microcirculation are from those countries in Europe, Asia, Australia and America where appreciable work in clinical hemorheology and microcirculation is being carried out. Each editor takes responsibility to decide on the acceptance of a manuscript. He is required to have the manuscript appraised by two referees and may be one of them himself. The executive editorial office, to which the manuscripts have been submitted, is responsible for rapid handling of the reviewing process.
Clinical Hemorheology and Microcirculation accepts original papers, brief communications, mini-reports and letters to the Editors-in-Chief. Review articles, providing general views and new insights into related subjects, are regularly invited by the Editors-in-Chief. Proceedings of international and national conferences on clinical hemorheology (in original form or as abstracts) complete the range of editorial features.
The following professionals and institutions will benefit most from subscribing to
Clinical Hemorheology and Microcirculation: medical practitioners in all fields including hematology, cardiology, geriatrics, angiology, surgery, obstetrics and gynecology, ophthalmology, otology, and neurology. Pharmacologists, clinical laboratories, blood transfusion centres, manufacturing firms producing diagnostic instruments, and the pharmaceutical industry will also benefit.
Important new topics will increasingly claim more pages of
Clinical Hemorheology and Microcirculation: the role of hemorheological and microcirculatory disturbances for epidemiology and prognosis, in particular regarding cardiovascular disorders, as well as its significance in the field of geriatrics. Authors and readers are invited to contact the editors for specific information or to make suggestions.
Abstract: Hematological disorders and alterations of erythrocyte deformability have been noticed in sportsmen after strenuous exercise. To try and understand these phenomena, the authors studied blood flow parameters before and after effort. This study involved 47 sportsmen undergoing a 20 min intensive exercise, and 44 controls. The following parameters were recorded before and after exercise: blood filtration, erythrocyte filtration, blood and plama viscosities, ATP, 2–3 DPG, RBC aggregation, biochemistry, NFS, reticulocytes, plasma hemoglobin, complete iron work-up, plasma proteins. Blood and plasma viscosities, hematocrit, leukocytes and plasma proteins were significantly increased (p<0.01) while whole blood filtration decreased (p<0.001); ATP, 2–3 DPG, erythrocyte…filtration and saturation coefficient remained unchanged. On first approach, hemorheological disorders do not seem to be caused by an alteration of erythrocyte deformability, but more likely by a tendency to rouleaux-formation noticeable through SEM. These disorders may also result from hemoconcentration (↑ Hematocrit, ↑ protids), from cell demargination and preferential increase in certain plasma proteins after exercise.
Abstract: A previously published power law fitting method for studying whole blood viscosity has been fully computerized to improve its reliability. To a large number of viscometric values for normal and pathological blood obtained by this system, multiple regression analysis was applied, relating the blood viscosity data to the main viscosity determinants, i.e., hematocrit (Hct) and plasma viscosity (η p ). The results confirm and quantify the relative importance of these two main determinants of whole blood viscosity and aggregability. Furthermore, it is possible to standardize data for these variables, to obtain indexes of “cellular component” of blood viscosity.
