The purpose of this study was to evaluate the effects of exogenous recombinant basic fibroblast growth factor (bFGF) on angiogenesis in severely ischemic tissue beds. We used a two-stage procedure to produce severe ischemia of the hindlimb of 34 New Zealand rabbits. The ischemic hindlimb received intramuscular injection of saline (group A), 1 microgram bFGF(More)
OBJECTIVE Arteriovenous fistulae traditionally have been placed in the upper extremity. Experience with groin hemodialysis access has been discouraging because of high infection rates and associated limb amputation. We reviewed our experience with angioaccess grafts in the groin to assess safety and viability in our hemodialysis patient population. (More)
The authors evaluated the effects of exogenous basic fibroblast growth factor (bFGF) in combination with intravenous methylprednisolone on neurological function and cord angiogenesis in a model of spinal cord injury. Cord injury was produced by extradural clip compression through a T-1 laminectomy. Rats were randomized to one of six groups. Group A was(More)
Since 1971, 688 consecutive carotid endarterectomies were performed in 612 patients in a community-based teaching hospital by 16 surgeons; 82% of the procedures were performed in patients who had suffered a transient ischemic attack, amaurosis fugax, or a previous stroke. Seven patients (1%) died, five of perioperative stroke and two of myocardial(More)
PURPOSE The purpose of this study is to investigate the efficacy and toxicity of tissue plasminogen activator (tPA) in treatment of postcataract fibrinous membranes. METHODS The authors injected 25 micrograms of tPA into the anterior chamber of 52 pseudophakic eyes with moderate to severe fibrinous membranes that developed after cataract surgery. (More)
BACKGROUND The function and patency of standard 6-mm Goretex (W.L. Gore and Associates, Flagstaff, AZ) and Impra (Impra, Inc., Tempe, AZ) expanded polytetrafluoroethylene (e-PTFE) grafts for hemodialysis as radial-antecubital linear arteriovenous fistulae for dialysis are compared. STUDY DESIGN A randomized clinical trial was conducted in two community(More)
The purpose of this study was to evaluate the long-term effectiveness of basic fibroblast growth factor (bFGF) in achieving neovascularization following ischemia from arterial ligation and to determine an optimal dosage level. We used an Ameroid constrictor to produce progressive occlusion of the left femoral artery of rabbits. At 2 weeks, the rabbits were(More)
Angiogenic growth factors including basic fibroblast growth factor (bFGF) have therapeutic value for chronic ischemia in nondiabetic animals. However, angiogenic therapy for chronic ischemia in a background of diabetes remains unexplored. In the present study, we evaluated the effects of exogenous bFGF on angiogenesis in streptozotocin-induced diabetic rats(More)
The demand on high speed Internet access has been rapidly growing due to various multimedia applications requiring high speed data transmission. WiMAX based on IEEE 802.16 standard is one of the most effective technologies among the existing solutions. With the current multicasting technique, the base station receives duplicated multicast IP datagrams via(More)
