Since the first deceased donor kidney transplantation in 1979, continuous efforts have been made to increase deceased organ donation in Korea. However, a critical shortage of human organs for transplant is still a serious problem and is partly caused by the absence of a system to actively identify and properly manage deceased donors in Korea. Considering this, Korea needs to create a new national system for deceased donor identification, management, and organ procurement. There are three kinds of organ procurement systems in the world: The "Spanish model", the "United States model", and the "other European model". We reviewed each system and suggested the optimal organ procurement system for Korea. We also proposed requirements for operating an organ procurement organization and increasing deceased organ donation. Further improvements in the organ procurement system will contribute to improve the current organ shortage.

PURPOSE: We compared wound healing between the conventional tie-over dressing and silicone sheeting after skin grafting in patients with skin defects. MATERIALS AND METHODS: Of a total of 30 cases of skin defects, 15 underwent conventional tie-over dressing and the remaining 15 underwent silicone sheeting skin grafting, we compared hematoma formation and infection status between the 2 techniques 1 and 2 weeks after operation. RESULTS: Hematoma was not observed in all cases. The wound infection rate decreased in silicone group. CONCLUSIONS: Silicone sheeting skin graft may be helpful in reducing wound infection.

BACKGROUND: The determination of serotype of enteroviruses is useful for the discrimination between sporadic and epidemic infections. The conventional serotyping method is time-consuming and labor-intensive. Recently, molecular method was introduced for the serotyping of enteroviruses. The aim of this study was to establish a method to isolate and analyze enteroviruses from various specimens utilizing molecular biological techniques and to determine which strains were phylogenetically related to clinical samples. METHODS: Clinical samples in this study included 164 cerebrospinal fluid (CSF), 136 stool, 15 sera, 6 throat swab, 5 urine, and 4 sputa, which were obtained from hospitalized patients, primarily infants or children presenting symptoms of aseptic meningitis in 1998. RD cells were used for enterovirus isolation. RT-PCR was performed with RD cell lysate showing CPE. The primers 011 and 012 were used for the VP1 region, and the primers EN1 and EN2 for 5'-UTR. The nucleotide sequences of VP1 region were determined and analyzed with BLAST program. RESULTS: Among 333 samples, only 23 samples produced CPE: 17 samples at first and six samples at the second blind passage. Fifteen isolates were related to coxsackievirus B2 two to echovirus 4, three to echovirus 6, and three to echovirus 18. All 23 viral isolates displayed a nucleotide sequence identity of 80-95%, compared with the reference serotypes. However, the identity was increased up to 93-100% when the VP1 region was translated into amino acids CONCLUSIONS: Since CB2 type was 55% among enteroviral isolates, the CB2 was determined as the major causative serotype of enteroviral meningitis in 1998. CB2 type was emerged between June and July, EC4 and EC6 was limited to July, and EC18 was in August.

Journal of the Korean Radiological Society 1993;29(3):355-361
The purpose of this study is to describe the magnetic resonance imaging (MR) findings of metastatic brain tumors with emphasis on the signal intensities of the lesion on MR. Thirty four patients with intracranial metastases were studies with MR imaging. The diagnosis was established on the basis of either brain biopsy or combination of brain MR findings and the presence of primary tumors. The primary tumors include lung cancer (n=18), breast cancer (n=3), stomach cancer (n=3), rectal cancer (n=1), renal cell carcinoma (n=1), hepatocellular carcinoma(n=1), ovarian cancer (n=1), thyroid cancer (n=1), melanoma (n=1) and unknown primary sites (n=4). The parenchymal lesions were solitary in 35% (12/34) and multiple in 65% (22/34). The size of the lesions was variable, ranging from several millimeters to 5cm in diameter. The corticomedullar junction of the cerebral heispheres was the most common location of the lesions (68%). The signal intensity of solid portion of the lesions was usually either isointense (44%) or hypointense (29%) on T1-weighted images, whereas it appeared in isointense (47%), hypointense (8%) or hyperintense (11%) on proton density-weighted or T2-weighted images. The remaining cases showed mixed signal intensities. The enhancement patterns were variable including nodular (<1cm) (6%), homogenous (19%), heterogeneous (10%), ring-like enhancement (22%) or mixed pattern(43%). The size of surrounding edema was larger than the tumor diameter in 76%. In conclusion, although there are no specific MR findings of intracranial metastasis except multiplicity, intracranial metastasis should be included in differential diagnosis with high priority, when a solitary mass showing isointensity on boty T1-and T2-weighted images with massive surrounding edema, especially in the corticomedullary junction of the cerebral hemispheres is encountered.
