저자들은 척수압박으로 하지마비를 보인 환자에서 수술 후에 급성 백혈병에 동반된 과립구성 육종으로 진단된 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma(GS) is an uncommon tumor composed of immature cells of the granulocytic series. Most case of GS occur in the course of acute leukemia and the blast crisis of chronic leukemia, Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disoders. GS has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia(AML) and the incidence of GS is reported to be higher in patients with t(8;21). GS occurs relatively commonly in africa and has been reported to affect 10-25% of black children presenting with AML. This is very rare case of granulocytic sarcoma with AML(FAB M5) presented with spinal cord compression which was supported by decompression laminectomy.

Recently according to the increase of the traumatic patient there is a trent for the prevalence of renal injuries to increase. The key point in managing the renal injuries is that we should make decision the treatment plan after accurate diagnosis from clinical symptoms, physical examination, radiologic studies. The goal of the management is the conservation of the renal function. The management of renal injuries by nonoperative or operative methods has been a subject of controversy for more than 2 decades. A aggressive immediated operative approach is generally advocated in some centers, while a more watchful conservative approach is endorsed in others. From January 1985 to May 1995, 159 patients with renal injury had been managed at Soonchunhyang University Hospital. Among 159 patients, 83 patients were classified with minor renal injury and 76 patients major renal injury. The Computerized Tomography was useful in diagnosing stage of injuries and detecting combined injuries which were not detected in excretory urography. All stabilized patients were managed by careful continuous observation, bed rest, appropriate fluid resuscitation and prophylactic antibiotic coverage, but unstabilized patients(17 cases) were managed by immediate operation. Complications occurred in 10 patients with a major renal injury associated with a devascularized fragment but not in other patients. In conclusion, the accurate diagnosis and treatment plan of renal injury with computerized tomography are important to avoid improper treatment. I conclude that conservative management of minor renal injury and major renal injury associated with vascularized fragment is a proper method of treatment. However, early surgical intervention should be considered in patients with major renal injury associated with devascularized fragment because of high complication rate and delayed surgical intervention rate.
The Mechanical Properties and Abrasion Behavior of Warp Knitted Fabrics for Footwear
Jeon, Youn-Hee,Jeong, Won-Young,Park, Jung-Woo,An, Seung-Kook The Korean Fiber Society 2003 Fibers and polymers Vol.4 No.4
The abrasion behavior of three kinds of warp knitted fabrics, which are normally used for upper sole of footwear, was evaluated. We measured the changes of mechanical and structural properties of each sample as abrasion cycle increased. Each sample showed similar trends in compression and surface properties but there were significant differences in abrasion rate among the samples. The mechanical properties showed remarkable differences with directions. The frictional coefficient (MIU) of fabric surface increased at the beginning of abrasion and decreased as abrasion cycles increased. The weight and thickness of the fabric linearly decreased with abrasion cycles. The surface roughness (SMD) and the compressional resilience (RC) decreased as abrasion cycles increased while compressional energy (WC) increased.
