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: Experiments were carried out to determine flow properties of oxygenated normal and abnormal blood (HbAA, HbAS, HbSS, HbSC, HbAC, HbCC and rat) using isolated artificially perfused rat mesoappendix microvasculature. Changes in arterial perfusion pressure (Ppa) and venous outflow (Fv) were recorded after the infusion of blood, and peripheral resistance unit (PRU) was calculated. In a series of experiments, pressure-flow recovery time (Tpf) was determined, and microphotography was done in selected experiments. Viscometry was carried out at a shear rate of 230 sec−1 In the perfused mesoappendix, HbSS and HbSC blood resulted in higher PRU as well as increase in…Tpf when compared to those for HbCC blood, though the latter was more viscous. Evidence is presented regarding the trapping and fragmentation of the irreversibly sickled cells (ISC) in microvasculature. The possible role of certain cellular factors favoring the apparently normal microcirculatory behavior of HbCC blood is analyzed.

Abstract: Analysis of extensive data in the literature plus a survey of our own limited clinical results indicate that changes in plasma viscosity (PV) primarily reflect alterations in the concentration of plasma macromolecules. The erythrocyte sedimentation rate (ESR) and zeta sedimentation ratio (ZSR) tests mainly detect the presence of macromolecules in the plasma which produce rouleaux or aggregates. The ESR test as presently used is, however, more prone to produce data supporting erroneous conclusion than the ZSR. It currently seems reasonable to eliminate ESR measurements and use only PV and ZSR measurements in clinical evaluations.
Abstract: The flow properties of blood were measured with various methods (rheologic analysis battery) before and after the infusion of 500 ml of a) 10 % low molecular weight dextran solution and b) of a 0,9 % sodium chloride solution in healthy volunteers. LMWD decreases blood viscosity, but increases plasma viscosity. Red cell filtration is decreased. There is no specific disaggregating effect of LMWD. After infusion of saline there is a transient decrease in blood and plasma viscosity, and an increase in filtration rate. No specific reduction in red cell aggregation could be found.
