Astrocytes become reactive after central nervous system injury, re-expressing glial fibrillary acidic protein (GFAP), vascular endothelial growth factor (VEGF), and nestin. Hypoxia-inducible transcription factor alpha (HIF-1α) is an important transcription factor for several genes including the VEGF and nestin genes, the expression of which generate(More)
OBJECTIVES The aim of this study was to investigate whether genetic variations in the eNOS gene were associated with intracranial and extracranial atherosclerosis in Koreans. MATERIALS AND METHODS We analyzed data on 282 consecutive Korean patients with atherosclerosis in intracranial (ICAS) or extracranial vessels, and compared with 300 healthy(More)
Pineal cysts are usually asymptomatic; however, they may rarely cause symptoms such as chronic headache, paroxysmal headache with gaze paresis, postural syncope, loss of consciousness, and sudden death. A 30-year-old woman with no specific medical history except chronic headache was found collapsed in a public toilet per se. Postmortem examination revealed(More)
Human cerebral microvascular endothelial cell line (hCMEC)/D3 cells, which are from a stable clonal cell line of human immortalized cerebral endothelial cells, were intra-arterially transplanted through the common carotid artery in a rat model of photochemical-induced cerebral ischemia. Their therapeutic effects on infarct size, blood-brain barrier (BBB)(More)
The major component of car washer fluid is a methanol. Intracranial hemorrhage is a rare but lethal complication in methanol poisoning. We report a case of massive bilateral basal ganglia hematoma in a 32-year-old man with methanol poisoning. He drank car washer solution twice time (about 500 ml), and was admitted to a territorial hospital 10 hours(More)
The recent report by Jun et al. [1] is valuable in that it highlighted nicotine as a lethal toxic chemical, which can be used for suicide. A 20-year-old man who was a non-smoker and had no disease history was found dead in a head-down position on his bed in his room in the morning by his mother. Through meticulous investigation, death scene investigators(More)
Tuberculosis remains a serious public health problem worldwide, especially in Korea. Although tuberculosis is generally considered a non-fatal chronic disease, deaths have occurred. In this case study, a 68-year-old man was admitted to the hospital with dyspepsia, vomiting, and abdominal pain. Nine hours later, he suffered severe hematemesis and died(More)
Forensic research using microRNA has been used so far only for the identification of body fluids, but its use in understanding biological processes in post-mortem pathology has not been studied before. Therefore, we performed experiments in mice to compare between freshwater and saltwater drowning models, and miRNA expression was analyzed in the brain(More)
Spontaneous hepatic rupture, which is a complication of hypertension in pregnancy, is extremely rare. However, high maternal and perinatal mortality rates are observed. Moreover, it is frequently associated with severe preeclampsia or HELLP syndrome (a group of symptoms that include hemolytic anemia, hepatic enzyme increase, and thrombocytopenia). About 80%(More)
