Alleles and genotype frequencies and its distribution pattern for the highly polymorphic D1S80 locus were determined in a Korean population sample, especially in Kwangju and Chonnam, by using PCR followed by agarose gel electrophoresis with ethidium bromide staining, a procedure called the amplified-fragment-length polymorphism(Amp-FLP) technique. And the data were compared with the alleles and genotype frequencies of Finnish population, North American Caucasian, and Korean population(Seoul) which had been reported. In 203 unrelated Korean individuals 27 alleles and 84 genotypes were observed. The highest allele frequency was in allele M24(0.128) and tne next orders were inalleles M18(0.126), M29, M30, M31, and M28 and the other alleles showed relatively low frequencies. The highest frequency of genotype was in M18/M24 and the next order frequencies were M18/M30, M19/M27 M29/M29, and M18/M29. The homozyous genotypes were in 9 alleles such as M29, M24, M31, and M18, and most of heterozygous genotypes were composed of alleles of each homozygous genotypes and /or the other alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals alleles, its composition of genotypes was 0.881(74/84), 183(0.901) of the 203 individuals were included. The VNTR D1S80 locus demonstrated a heterozygosity of 0.872. From the above results, VNTR D1S80 locus may be a powerful locus to identify individuals, however, the allele frequencies was not closely related to the genotype pattern, and the alleles of homozygous genotypes influenced on the chance of the recombination of the various genotypes. It is necessary to analyze the genotype distribution and the recombination pattern of alleles as well as alleles and genotype frequencies in each populations for statistical test at most highly polymorphic loci.

Retropsoas space below the level of kidney has been suggested as a portion of inferior extensions of perirenal and anterior and posterior pararenal spaces. With this being true, the space may play an important role in disease extension. A study was performed to verify the existence of retropsoas peritoneal recess by means of identifying the extension of bowel loops into this space. Abdominal CT scans of 146 cases evaluated retrospectively revealed extension of 5 small bowel and 7 large bowel loops (6 descending and 1 ascending colons)(n=12/8.2%) into the retropsoas space verifying its existence. Since pathologic collection within the retropsoas space might be falsely inter preted as a retroperitoneal pathology and percutaneous uroradiologic intervention could result in intraperitoneal injury or contamination without the knowledge on the existence of this space, observation of this space is essential in CT scans.

Biofeedback is the treatment of choice for functional defecation disorders such as idiopathic chronic constipation and neurogenic fecal incontinence. The pre-existing biofeedback systems have many disadvantages. The aims of current project are, first, to develop the biofeedback system into the application software in the Windows environment, and, second, to assess the possibility of clinical usage for patients with functional defecation disorders. The hardware and software of the BASCO (Biofeedback Anal Sphincter Control) system were based on the signal measurement and signal processing of anal sphincter EMG (Electromyography). BASCO system was applied to 5 normal healthy controls and 20 patients with functional defecation disorders. Patients group was categorized as constipation group (N1=15) and incontinence group (N2=5). With use of current system, EMG-based biofeedback therapy was performed, and the outcome was analysed. Anal EMG signal data was processed by the software, and displayed in the monitor of personal computer. The software of EMG-display and database management were adequately operated. In N1 group, a paradoxical elevation or equalized activity of anal EMG pattern was shown in the simulated defecation. In N2 group, low electrical activity was shown. These findings were used for the EMG-based biofeedback therapy as a pilot study. The clinical symptoms were improved in 12 of N1 group and 3 of N2 group in the period of 3.7 (range, 1~12) months follow-up. In Conclusion, newly-developed BASCO system was adequately operated in the volunteer and patients groups. The multi-tasking and multi-processing functions were adequately shown in the real time. Current results could be used for clinical appraisal. Specifically, this system could be used for the practical application of biofeedback therapy in the patients with chronic constipation or fecal incontinence.

A retrospective comparative study of MRI and CT in 24 patients with diffuse axonal injury (DIA) was undertaken. Three-quaters of the lesions were non-hemorrhagic, and the sites of involvement were lobar white matter (96%), corpus callosum (70%), and rostral brainstem (42%), in descending order. MRI was singnificantly more sensitive than CT in detecting DAI lesions. The average number of DAI lesions was higher with increasing clinical stage of the injury. MRI is more valuable than CT for staging the full magnitude of the injury and in predicting the neurologic prognosis of DAI lesions.

Hypertensive encephalopathy is characterized by an acute, severe rise in blood pressure associated with headache, nausea, vomiting, altered mental status, and focal neurologic deficits, and rapid improvement after control of blood pressure. An eight-year old boy had been admitted with symptoms of red urine, fever, headache, convulsion, and visual blurring of vision. Blood pressure was 140/90mmHg, and CSF exam revealed WBC 8/mm3, glucose 83mg/dL, protein 106mg/dL. Serum C3 was 8mg/dL, C4 17mg/dL, ASO 1,024 Todd units. Brain CT showed non specific findings, however, MRI revealed symmetric high signal intensity lesions on T2WI over the parieto-occipital areas bilaterally. These lesions had been completely resolved on the following MRI 4 weeks later.
