This study explored the effect of focal cerebral contusion on the expression of ApoE and S-100, and its significance in determining the time of brain injury. Based on a rat model of cerebral contusion, immunohistochemistry was used to analyze the expressions of S-100 and ApoE at different time points after injury. Thirty minutes following cerebral contusion, ApoE protein expression was signific...

Astragaloside (AST) is traditionally prescribed for the prevention and treatment of cerebrovascular diseases. We directly tested the therapeutic effects of AST in a rat model of traumatic brain injury (TBI). One hour after the onset of TBI rats were given Saline (1 ml/kg) or AST (20-80 mg/kg) via i.p. injection. AST causes the attenuation of TBI-induced cerebral contusion, neuronal apoptosis, a...

Traumatic brain injuries were analysed clinically and experimentally by recording stationary potential(SP) which is a very stable component in the electrical phenomena of the brain. SP value is considered to change positively or negatively only when there are organic lesions, severe metabolic changes of the brain, or epileptic seizures. Clinically, we have measured the SP of 103 head-injure...

A 67-year-old woman was hospitalized for rehabilitation from the after effects of a traumatic brain injury. In addition to memory impairment, attention disorder, and executive dysfunction, she experienced musical hallucinations. Brain magnetic resonance imaging revealed cerebral contusion in the bilateral temporal lobes and the left frontal lobe. Case reports of musical hallucinations caused by...

Rapid development of tissue engineering techniques has led to the possibility of treating central nervous injuries with Schwann cells (SCs). However, certain characteristics of SCs, such as a low proliferation ability, greatly restrict their use. The aim of the present study was to investigate whether SCs differentiated from adipose‑derived stem cells (ADSC‑SCs) could used to promote functional...

Focal cerebral contusions can be dynamic and expansive, leading to a delayed neurological deterioration. In head--injured patients, the rise in intracranial pressure (ICP), subsequent to uncontrollable swelling, is the only and the most frequent cause of death. Studies show that brain swelling, after traumatic brain injury (TBI), is caused by brain edema rather than cerebral blood volume (CBV)....

Received Nov.2011; Received in revised form Dec.2011; Accepted Jan.2012 ABSTRACT Statement of Problem: Although advances in technology have led to improvements in man’s life in different aspects, statistics show that the incidence of fractures is increasing in different regions of the body. Recent studies show that midface fractures are strongly associated with patient's death. The exact relati...
