PURPOSE Stem cell transplantation has been extensively studied as individual therapies for ischemic stroke. The present investigation is an initial effort to combine these methods to achieve increased therapeutic effects after brain ischemia. Cell transplantation may recover massive neuronal loss by replacing damaged brain cells. METHODS Undifferentiated mouse embryonic stem (mES) cells were ...

conclusions major vascular injuries in our center occurred in young men, frequently because of stab wounds. popliteal injuries mostly caused by motor vehicle accidents was the second most common arterial injury, followed by combined ulnar and radial injuries. vascular reconstruction in the first hours after trauma may prevent many unnecessary and preventable amputation procedures. results most ...

There is evidence that aspirin is partially effective in the prophylaxis of various vasoocclusive disorders. This article reviews pharmacologic opportunities for improvement over and above the therapeutic effect of aspirin. It is concluded that several rational possibilities merit consideration, in particular, the use of combinations of drugs that affect the thrombotic process at different poin...

Coronary angiography has proved beyond doubt that complete coronary occlusion is the rule in the very early hours of infarction. The 60% to 80% rate of coronary recanalization after thrombolytic therapy has proved that thrombosis is a major component of the occlusion at the time when the procedure is performed a few hours after the onset of symptoms. However, the trigger for coronary thrombosis...

BACKGROUND AND PURPOSE Some reports of reconstructive management of carotid blowout syndrome (CBS) with stent-grafts are promising, but some are unfavorable. This study sought to evaluate the hemostatic efficacy, safety, and outcome of reconstructive, endovascular stent-graft placement in patients with head-and-neck cancers in association with CBS. METHODS Eight patients with head-and-neck ca...

Selective inhibitors of thromboxane synthase have two theoretical advantages over inhibitors of the cyclooxygenase enzyme as potential antithrombotic compounds. First, they do not prevent formation of prostacyclin, a platelet-inhibitory, vasodilator compound, coincident with inhibiting thromboxane biosynthesis. Second, the prostaglandin endoperoxide substrate that accumulates in the platelet in...

Background. Hazards of liver surgery have been attenuated by the evolution in methods of hepatic vascular control and the anesthetic management. In this paper, the anesthetic considerations during hepatic vascular occlusion techniques were reviewed. Methods. A Medline literature search using the terms "anesthetic," "anesthesia," "liver," "hepatectomy," "inflow," "outflow occlusion," "Pringle," ...
