This study of hemorrhagic shock syndrome in dogs evaluates commonly used therapeutic procedures on the basis of ability to correct specific vascular decompensatory episodes associated with progressive refractoriness to blood transfusion. Using specific criteria (vasomotion, responsiveness to vasoconstrictor stimuli, tone of arterioles and venules and capillary blood flow), it was found that pre...

BACKGROUND Blood transfusion is used to treat acute anemia with the goal of increasing blood oxygen-carrying capacity as determined by hematocrit (Hct) and oxygen delivery (DO2). However, increasing Hct also increases blood viscosity, which may thus lower DO2 if the arterial circulation is a rigid hydraulic system as the resistance to blood flow will increase. The net effect of transfusion on D...

Isolated subclavian artery is a rare anomaly where the artery, instead of originating from aorta, connected to ipsilateral pulmonary via ductus arteriosus. Presentation varies asymptomatic vertebrobasilar insufficiency and claudication arm. About 100 odd cases were reported in literature. Some them underwent definitive surgical repair, ie, reimplantation others percutaneous closure patent arter...

The sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. The passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. Leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematop...

BACKGROUND Stem cell therapy has been proposed to enhance the salvage of critically ischemic limbs. OBJECTIVE Assess the efficacy and safety of the implantation of non-mobilized peripheral blood angiogenic cell precursors (NMPB-ACPs) in patients with critical limb ischemia (CLI) who were poor candidates for standard revascularization treatment options. MATERIAL AND METHOD Six patients with ...
