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...

Recent technological advances have led to improvements in social well being of man’s life in all aspects. This improving and advanced lifestyle is the major cause for some debilitating problems like road traffic accidents. Statistical analysis in literature shows that head and maxillofacial injuries are the most common of these injuries. Recent studies show that fractures of midface are strongl...

By RUDR DUTT, l.m.s. Assistant Surgeon, Dera Ghazi Khan A Hindu adult male, after receiving severe head injuries, proceeded from one place to another in search of assistance, but failing to find any he finally went to the local police station and made a report as to how the injuries were received. The search entailed a walk of well over two miles. The following injuries were found after death :...

Administration of L-arginine has been shown to increase cerebral blood flow and reduce neurological damage after experimental traumatic brain injury. The purpose of this study was to examine the optimal dose and time window for these neuroprotective effects. In a dose response experiment, doses of L-arginine ranging from 37.5 to 600 mg/kg were administered 5 min after a 5-m/s, 3-mm, controlled ...

Behavioral hypersensitivity is common following spinal cord injury (SCI), producing significant discomfort and often developing into chronic pain syndromes. While the mechanisms underlying the development of behavioral hypersensitivity after SCI are poorly understood, previous studies of SCI contusion have shown an increase in amino acids, namely, aspartate and glutamate, along with a decrease ...

To determine the utility of fiberoptic bronchoscopy (FFB) in the short-term evaluation of patients with trauma, we identified 53 consecutive patients (45 male patients; mean age, 36 years) seen over a ten-year period who had FFB performed within the first three days of trauma to the chest and upper airway. There were eight deaths. Fifty patients had blunt trauma to the chest. These were mostly ...

OBJECTIVE Spinal cord injury (SCI) is accompanied by disruption of the blood-spinal cord barrier and subsequent extravasation of fluid and proteins, which results in edema (increased water content) at the site of injury. However, the mechanisms that control edema and the extent to which edema impacts outcome after SCI are not well elucidated. METHODS Here, we examined the role of aquaporin-4 ...
