Despite of advances in prehospital and intraoperative care, vascular injury remains the primary cause of death following abdominal trauma. We reviewed 20 cases of major abdominal vascular injuries by trauma treated at the Department of Surgery of Capital Armed Forecs General Hospital between March, 1990 to March, 1992. The results were as follows' 1) The most common group of age was in 3rd decade, and the most frequent group of rank was private. All cases were male. 2) The mechanism of injury was blunt trauma in 11 cases(55%), penetrating trauma including gunshot and explosive wounds in 7 cases(35%) and iatrogenic trauma in 2 cases(10%). The most lethal mechanism of injury was gunshot wound. 3) The factors associate with increased mortality rate were initial systolic blood pressure less than 70 mmHg(Mortality rate= 71.4% or 5/7), initial hemoglobin concentration less than 10mg/dl(Mortality rate= 55.6% or 5/9), 10 or more units of transfused blood(Mortality rate= 57.1% or 4/7), 3 or more associted visceral injuries less than(Mortality rate=41.7% or 5/12) and site of injured vessel(the most lethal site of injured vessel was aorta). 4) Methods of vascular repair were ligation(46.2% or 12/26), lateral repair(42.3% or 11/26), reanastomosis after resection(7.7% or 2/26) and nephrectomy(3.8% or 1/26). 5) Causes of death were hypovolemic shock in 4 cases (80%), DIC in 1 case(20%). 6) Postoperative complications in survivors, in order of frequency were pulmonary problems (26.3%), wound infection(21.1%), DIC(10.5%), urethral stricture(10.5%) and renal failure(5.3%).

Vascular wall biology is under intense study by researchers interested in the cause of intimal hyperplasia and atherosclerosis. In vivo studies of vascular wall disease are limited by difficulty controlling numerous variables in a complex environment. This has led to study of cellular process in vitro, where these variables can be more precisely controlled. A role for interactions between endothelial cells(EC) and smooth muscle cells(SMC) in vascular growth control has been suggested by developmental studies. Although it is well documented that EC produce a vairety of diffusible factors known to influence SMC behavior, the signals that regulate the expression of these factors in EC and the precise role that EC-SMC interactions play in vascular growth control remain elusive. During vessel deyelopment, both EC and SMC grow and proliferate, but once the blood vessel matures, these cells rarely divide. The author hypothesize that EC are involved in the control of SMC proliferation. In this study the author provide evidence for the density-dependent production of a novel SMC growth inhibitor by EC. And to better stimualte the vascular wall in an in vitro environment, EC and SMC are grown on opposite side of a thin semipermeable collagen membrane with a molecular weight cutoff 2,000 da. This technique maintains the normal luminal/abluminal orientation of the EC and SMC and allows the cells to grow within close proximity, limiting the diffusion barrier for potential biologic mediators. The results were as follows; 1) Preconfluent conditioned medium(CM) of HUVEC stimulated SMC proliferation and postconfluent CM of HUVEC inhibited SMC proliferation. And also SMC DNA content and ^3H-thymidine incorporation was increased by preconfluent CM and decreased by postconfluent CM. 2) Preconfluent CM of BAEC also stimulated SMC proliferation(13%) and postcofluent CM of BAEC inhibited SMC proliferation(5.95%). 3) Preconfluent HUVEC/SMC coculture stimulated SMC proliferation(7.0% ) and postconfluent HUVEC/SMC coculture inhibited SMC proliferation(13.67%). And ^3H-thymidine incorporation of SMC was increased 24.0% by preconfluent HUVEC/SMC coculture but decreased 10.48% by postconfluent HUVEC/SMC coculture. 4) Preconfluent CM of BAEC/SMC coculture stimulated SMC proliferation(18.0%) and postconfleunt CM of BAEC/SMC coculture inhibited(14.1l%). As a conclusion, this study suggest the inhibitor of SMC secreted from EC is smaller than 2,000 dalton and is not well known biologic mediator.

The cystic lymphangioma of adrenal gland is a rare benign tumor. It has not been reported in Korea. The present study represents the first report of cystic lymphangioma of adrenal gland in Korea. It's exact etiology is obscure but thought to be related to a congenital abnormal development of lymphatic system. In addition, it is associated with the failure of communication with the central lymphatic system. The clinical significance of cystic lymphangioma is related to its size manifest itself as a palpable mass early in life. Preoperative clinical and laboratory characteristics are non-specific. Recently we experienced a case of cystic lymphangioma of the adrenal of the adrenal gland in 28-year-old female and reported it with a review of the literature.
