Whitaker lecture 1996: Microcirculation, biomedical engineering, and artificial blood

The development of artificial blood requires the understanding of how blood behaves, at the level of the microcirculation. A number of measuring systems have recently become available that allow analysis of the transport properties of blood and the microvessels in terms of pressure, flow, the dynamics of their diameter changes, and the rate and manner of oxygen delivery. Findings from this technology have led to the development of an analytical framework with which to assess the consequences of altering the physical properties of blood and to verify quantitatively theoretical predictions. Results show that blood viscosity and oxygen-carrying capacity are directly related, and must be jointly modified in a prescribed manner to maintain tissue oxygen delivery. The use of optical techniques to asses flow and oxygen delivery in experimental animal models show that the consumption of oxygen by the microvessel wall is an important determinant of tissue oxygenation. Furthermore, the viscosity of blood and/or the mixture of blood and an artificial substitute must achieve a viscosity that is close to normal. Low blood viscosity is not necessarily beneficial, unless blood flow velocity rises to maintain the shear stress at the wall needed for the generation of local vasodilators. Manipulating physical properties of currently available modified hemoglobins by mixing them with conventional plasma expanders yield fluids that may provide optimal blood replacements.     

A human model of platelet-leucocyte adhesive interactions during controlled ischaemia in patients with peripheral vascular disease

AIMS: In humans, little is known about the effects of platelet-leucocyte interactions on blood viscosity and microvascular perfusion. This study tested the hypotheses that (1) activation and interactions between platelets and leucocytes may have an impact on microvascular blood viscosity and perfusion in patients with stage II peripheral arterial occlusive disease, and (2) a powerful antiplatelet drug such as Clopidogrel might help to improve microvascular perfusion by reducing platelet-leucocyte activation and blood viscosity. METHODS: Plasma concentrations of certain markers of leucocyte and platelet activation, in addition to low and high shear rate blood viscosity, were measured before and after a repeated exercise treadmill test. Functional parameters including maximum walking time, transcutaneous oxygen pressure, and half recovery time were also measured. RESULTS: Blocking platelet activation only with a single dose of Clopidogrel (300 mg) did not improve microvascular blood viscosity and perfusion after repeated exercise, but a significant improvement in microvascular perfusion during controlled ischaemia and a lack of post exercise increase in low shear rate blood viscosity was achieved when both platelet and leucocyte activation were suppressed by a relatively longer treatment with Clopidogrel (four days). CONCLUSIONS: Clopidogrel, by inhibiting platelet activation and aggregation, might also block the vicious cycle of leucocyte-platelet activation, thus improving the functioning of the microcirculation.

Hemorheological Effects of Ortho-Isobornyl Phenol Derivative under Conditions of Brain Ischemia in Rats

Hemorheological activity of 4-methyl-2,6-di-isobornyl phenol, a new o-isobornyl phenol derivative, was studied under conditions of experimental prolonged partial cerebral ischemia. Brain ischemia is associated with hemorheological disorders which can be characterized as blood hyperviscosity syndrome: increased viscosity of the whole blood (within a wide range of shear rates), plasma viscosity, fi brinogen content in blood plasma, and platelet aggregation; deterioration of platelet deformability and reduced availability of oxygen for tissues. A course (5 days) of intragastric 4-methyl-2,6-di-isobornyl phenol (100 mg/kg) prevented the development of blood hyperviscosity syndrome by modulating blood macrorheology (reduction of plasma viscosity and fi brinogen content) and microrheology (reduction of erythrocyte aggregation and improvement of their deformability).     

Effects of altering O2 delivery on VO2 of isolated, working muscle.

Maximal oxygen consumption (VO2 max) and muscle blood flow (Q max) were measured in an isolated gracilis muscle preparation before and after alteration in perfusion pressure (BP), arterial oxygen saturation (SaO2), and hemoglobin concentration (Hb). Q varied directly with BP and inversely with Hb (viscosity) but was unaffected by changes in arterial SaO2. VO2 max varied directly with oxygen delivery under all conditions. These results indicate that VO2 max is normally limited by oxygen delivery rather than any intrinsic limiting of oxygen consumption of the muscle.     

光量子加血卟啉疗法对动物移植瘤生长的影响及机制探讨

目的：探讨自血光动力学疗法对动物移植瘤生长的影响及机制。方法:本实验选用经腹股沟皮下接种W256瘤细胞株形成实验性荷瘤大鼠40只，采用光动力学疗法对患有移植瘤大鼠进行治疗，并同时检测血浆、肝脏及瘤组织中超氧化物歧化酶的活力及氧自由基代谢产物丙二醛含量。结果:大鼠输入经紫外光照射之血后，其肿瘤生长速度明显减慢（P<0.05），大鼠输入注有血卟啉的血后，其肿瘤生长亦显著减慢（P<0.01）；大鼠输入经紫外光照射并含有血卟啉的血后，其肿瘤生长速度比其它组均显著减慢（P<0.01）；光照射组大鼠在肿瘤生长减慢同时，其血浆和瘤组织中SOD活力明显升高；MDA含量显著降低（P<0.05，P＜0.01）；而血卟啉组大鼠其血浆和瘤组织中SOD活力明显降低，MDA含量显著升高（P<0.01）；光照射加血卟啉组大鼠，在肿瘤生长减慢同时，其血浆、肝脏及瘤组织中SOD活力较其它组均显著降低，MDA含量显著升高（P<0.01） 。结论：经紫外光照射的血或含有血卟啉的血均对肿瘤生长有抑制作用，而且紫外光照射与注入血卟啉相结合对抑制肿瘤生长效果最佳，该光动力学疗法对肿瘤治疗作用机制之一可能是通过产生单态氧而杀伤瘤细胞的。     

Hypoxia and hemorheological properties in older individuals

Hypoxia is caused by insufficient oxygen availability for the organism leading to reduced oxygen delivery to tissues and cells. It has been regarded as a severe threat to human health and it is indeed implicated in pathophysiological mechanisms involved in the development and progression of many diseases. Nevertheless, the potential of controlled hypoxia interventions (i.e. hypoxia conditioning) for improving cardio-vascular health is gaining increased attention. However, blood rheology is often a forgotten factor for vascular health while aging and hypoxia exposure are both suspected to alter hemorheological properties. These changes in blood rheology may influence the benefits-risks balance of hypoxia exposure in older individuals. The benefits of hypoxia exposure for vascular health are mainly reported for healthy populations and the combined impact of aging and hypoxia on blood rheology could therefore be deleterious in older individuals.This review discusses evidence of hypoxia-related and aging-related changes in blood viscosity and its determinants. It draws upon an extensive literature search on the effects of hypoxia/altitude and aging on blood rheology. Aging increases blood viscosity mainly through a rise in plasma viscosity, red blood cell (RBC) aggregation and a decrease in RBC deformability. Hypoxia also causes an increase in RBC aggregation and plasma viscosity. In addition, hypoxia exposure may increase hematocrit and modulate RBC deformability, depending on the hypoxic dose, i.e, beneficial effect of intermittent hypoxia with moderate dose vs deleterious effect of chronic continuous or intermittent hypoxia or if the hypoxic dose is too high. Special attention is directed toward the risks vs. benefits of hemorheological changes during hypoxia exposure in older individuals, and its clinical relevance for vascular disorders.
