BACKGROUND AND OBJECTIVES: Perfluorocarbon exposed sonicated dextrose albumin (PESDA) microbubbles has been suggested to facilitate thrombus disruption under the transcutaneous ultrasound (US). Thus, we investigated whether such a noninvasive approach could augment thrombolytic effect of fibrinolytic agent in an experimental thrombotic model. MATERIALS AND METHODS: Thrombus formation was induced with electrical injury in the rabbit iliofemoral arteries (n=20): Thrombus occlusion was documented by angiography in all arteries. In the control group, only tissue plasminogen activator (t-PA, 3 mg/kg) was administered intrav-enously in five rabbits. In the Group 1 (n=9), injured arteries were exposed to transcutaneous US (20 kHz, 30 W/cm2, continuous mode) with t-PA (3 mg/kg). In the Group 2 (n=6), the same treatment was given while administering PESDA continuously (10 ml/min, intravenous). Angiographic results were evaluated at 10 minute interval for 1 hour respectively. RESULTS: In the control group, two of five iliofemoral arteries (40.0%) were recanalized and one of nine iliofemoral arteries (11.1%) was recanalized in Group 1. In contrast, four of six iliofemoral arteries (66.7%) were recanalized angiographically in Group 2 (p=0.392 vs. control group: p=0.047 vs. Group 1). However, late reocclusion occurred in all iliofemoral arteries of Group 2. CONCLUSION: Although PESDA with transcutaneous US significantly enhanced initial angiographic patency rate of t-PA, it was associated with high rate of reocclusion. Further studies will be necessary for clinical application of this noninvasive method in acute arterial occlusion.

We reports a woman's death caused by massive intraabdominal hemorrhage, who was in chronic alcoholic state with advanced liver cirrhosis and found dead in her room. No macroscopic source for the bleeding was found in her intraabdomen and there was no circumstances of traumatic forces to the individual's body around the death. The presenting unsuspected death could be consistent with the forensic pathological cases described as sudden, unexpected death due to massive nontraumatic intraabdominal hemorrhage in association with liver cirrhosis by DiMaio in 1987.

Authors have anthropologically measured the human skeleton from a Dugmoe Tomb of the technopolis of Kwang-ju city. The results obtained were as follows : 1. The human skeleton was thought to be constructed at the beginning of the period of the Chosun, judging from the Dugmoe Tomb. 2. It is female and its stature is estimated as about 163-165cm. The age of the skeleton is estimated to be late 50. 3. The cranial index is 77.09mm and the type is mesocephaly. 4. The cranial length-height index and the cranial breadth-height index were hypsicrane and acrocephaly. 5. The orbital index 95.0mm and the type is hypsiconch. 6. The humerus is comparatively long, slender and has more rounded diaphysis. 7. The femur is similar that of present day, and the type is platyer. 8. The abrasion of the occlusal surface of the teeth was 2.5 point.

The scaphoid is the most commonly fractured carpal bone and the nonunion of the scaphoid has continued to represent a challenge to the surgeon who treats hand injuries. The are many treatment modalities and the technique of bone grafting described by Otto Russe in 1960, which is quite appropriately called the Matti-Russe procedure, has become a well-accepted method of treating nonunion of the scaphoid. And the results of this method has been presented by several authors. At the Department of Orthopedic Surgery, Seoul National University Hospital, From May 1985 to September 1988, ten cases of the scaphoid nonunion had been treated by Matti-Russe procedure and followed up more than 1 year. Fracture healing was observed in all ten cases. Seven patients were totally free of pain both at rest and at excercise and three patients noted moderate pain at excercise. All patient were satisfied with the results of operation and none felt worse.

Four cases medical accidents related to the iatrogenic injury of neck vessels are reported. The first case was a 54-year-old woman. Under the diagnosis of the herniated cervical disc, the operation was performed. After five hours from starting the operation, respiratory difficulty, facial cyanosis and syncope were found, suddenly. The autopsy finding were large hematoma at the posterior portion of neck organ and perforation of right carotid artery. The second case was a 61-year-old woman. Under the diagnosis of the aneurysm of the anterior communicating artery, the coiling and embolization were performed. After one hour from removal of catheter of right carotid artery, respiratory difficulty, facial cyanosis and syncope associated with right neck hematoma were found, suddenly. Eventually, she died after 41 days due to hypoxic brain injury. The third case was a 55-year-old woman. Under the diagnosis of the thyroid cancer, total thyroidectomy was performed. After three hours from operation, respiratory difficulty, facial cyanosis and syncope associated with severe neck hematoma were found, suddenly. Eventually, she died after 25 days due to hypoxic brain injury. The last case was a 34-year-old man. He visited the hospital due to stab wound of left neck. The irrigation and simple suture were performed at the first visit. After he went home, respiratory difficulty and syncope were found, suddenly. He returned the hospital and cardiopulmonary resuscitation was performed. However, he died. The autopsy finding were large hematoma around the neck organ and stab wound of left carotid artery.

This studies were examined and compared the immunohistochemical distribution of the two calcium -binding proteins calbindin D -28K and parvalbumin positive neurons in the brain stem and spinal cord after transection of spinal cord in rats. In this experiment, calbindin D -28K immunoreactive neurons were mainly found in many pyramidal cells distributed in the brain stem and spinal cord of rats. Calbindin D -28K neuropil labeling was strongly noted in brain stem and in spinal all segments of the spinal cord. In contrast to parvalbumin, little differences were found in distribution, size and morphology of calbindin D -28K cell body or neuropil staining in the brain stem and spinal cord. Parvalbumin immunoreactive cells were demonstrated in all lamina of the gray matter of the spinal cord. These immunoreactive cells had the most high density in the layer I and II dorsal horn and several nuclei of the ventral horn of the all segments of the spinal cord. These immunoreactive cells between the brain stem and spinal cord were quite different markedly in number, cell size and morphology The number of parvalbumin positive cells were more than twice in the brain stem and spinal cord compared to the calbindin D -28K positive cells. Calbindin D -28K and parvalbumin -immunoreactive somata were round, oval, spindle and polygonal in shape, and the positive neurons were unipolar, bipolar, multipolar and horizontal in shape. The diameters of the somata of the two positive neurons were 30 ~40 micrometer, respectively. Also dendrites of two positive neurons were densely arrayed in arborization.

This study presents seven patients with hypothalamic hamartomas diagnosed on the basis of MRI. Histological confirmation was performed in one patient who underwent surgery. Four patients presented with epilepsy, including gelastic seizures. Other symptoms were behavior abnormalities in 3 patients and precocious puberty in 4 patients. We classify hypothalamic hamartomas into four subgroups according to MRI finding: Types la lesions were less than 100mm in lesions less than 10mm and mammillary body. Type lla lesions were more than 100mm in diamenter and sessilely attached to hypothalamus with slight hypothalmic displacement and Type llb lesions more than 10mm and with marked displacement of hypothalamus. We could achieve good result with surgical resection in one patient with Type llb hamartoma associated with gelastic seizure that was unresponsive to medical treatment. We performed gamma knife radiosurgery in three patients with gelastic seizue(2 patients with Type lla and 1 patient with Type llb) and three patients with precocious puberty(2 patients with Type la and 1 patient with Type lla 1 patient with Type llb) and three patients with precocious puberty(2 patients with Type la and 1 patient with type lb). The authors propose direct surgery as a treatment for this progressive syndrome and gamma knife radiourgery is alternative treatment for high risk patients.
