Free radicals formed around the edematous areas of the brain can cause lipoperoxidation of the cellular membrane, followed by calcium influx into the cell through calcium channels. These secondary insults may aggravate vasogenic brain edema. Since phenobarbital is a free radical scavenger, methylprednisolone has an antilipoperoxidation effect; and(More)
BACKGROUND AND PURPOSE Hemodilution lowers the total circulatory red cell mass and blood viscosity and thereby may alter the time of passage of red cells and plasma through cerebral microvessels. This study was designed to clarify this question. METHODS Adult Wistar-Kyoto rats, aged approximately 32 weeks, were divided into hemodilution and control(More)
STUDY DESIGN A simple method, thin-slice contrast-enhanced computed tomographic (CT) scan, was evaluated as a first-line rapid screening procedure for diagnosing traumatic occlusion of the vertebral artery at the craniovertebral junction. OBJECTIVES This procedure was performed in patients suffering from injuries of the high cervical spine or the(More)
A spontaneous rupture of the extensor pollicis longus (EPL) tendon is associated with rheumatoid arthritis, fractures of the wrist, systemic or local steroids and repetitive, and excessive abnormal motion of the wrist joint. The authors encountered a case of a spontaneous rupture of the EPL tendon. The patient had no predisposing factors including trauma or(More)
The objective of this study was to determine whether hemodilution could normalize the mean transit times of red blood cells (Tr) and plasma (Tp) through cerebral microvessels in a partially ischemic brain. Wistar-Kyoto (WKY) rats, aged 30-40 weeks, were divided randomly into three groups. The first group was the nonocclusion, nonhemodilution (NN) normal(More)
PURPOSE We aimed to investigate the cardiopulmonary effects of pressurized cement insertion in elderly patients undergoing cemented hip hemiarthroplasty. MATERIALS AND METHODS We conducted a randomized prospective study on elderly patients undergoing cemented hip hemiarthroplasty. Patients were divided into pressurized and non-pressurized groups based on(More)
Recent experimental results indicate that cerebral glia lining and glia limitans may be barriers for plasma protein extravasated from injured cerebral microvessels flowing into the adjacent subarachnoid space. Therefore, it has been hypothesized that a transdural cortical stabbing which opens both the pia lining and glia limitans may facilitate drainage of(More)
