PURPOSE: To evaluate the anatomic and functional change in acutely obstructed kidneys, and the probability of functional recovery after resolving the obstruciton. MATERIALS AND METHODS: There were 5 animal groups(6 rabbits in each group)-normal control group, 4 acute ureteral obstruction group. Each of the latter group was imaged with Gd-DTPA enhanced dynamic MR 2, 6, 24, and 48 hours after ligation of the left proximal urter, respectively. We compared the findings of dynamic MR imaging and histopathological findings. RESULTS: We could observe centripetal movement of dark band pattern which could be defined as 3 phasesrenal cortex, outer medulla, and inner medulla in normal rabbits. The appearance of the dark band pattern was delayed or absent in ureteral obstruction group with a linear relationship to the duration of the obstruction. CONCLUSION: Gd-DTPA enhanced MR can be used to differentiate acute obstructive nephropathy from other causes of nephropathy and foretell the prognosis of the obstruction.

Authors attempted to examine the development of keratinocyte in the human fetal epiderrnis in term of the appearance of principal product of differentiation, the keratins. Immunohistochemical study (ABC method) using anti-prekeratin antibodies and anti-keratin antibodies was carried out on sampled skin from 9 human fetuses ranging in estirnated gestational age from 12 weeks to 27 weeks. As early as 12 weeks of embryonic life, the epidermis contained cytokeratin. At this stage of development, the embryonic epidermis consists of three-cell layer .' basal layer, intermediate layer, and periderm, all of them staining for prekeratin and keratin. A thick cornified layer developed at 24 weeks but was not stained for prekeratin and keratin. Hair germ of 12 week-fetus was recognized as bulges of basal cells that were stained for prekeratin and keratin. At 18 weeks of estimated gestational age, development has advanced to the bulbous hair peg stage at which point the primordia of nearly all the final structural components of follicles were established. In the final structureal cornponents of the follicles, outer root sheath and sebaceous gland were stained for prekeratin and keratin, whereas cortical and cuticular elements and inner root sheath were negative. There was no difference between immunostaining results for prekeratin and keratin except for the staining intensity. The appearance of these proteins early in development suggests their potential value in utero in the recognition of keratinization disorders.

The spine can be divided into two structural columns; an anterior column consisting of vertebral bodies, discs and ligaments and a posterior column consisting of the neural arch, facet joints and interconnecting ligaments. Disruption of both anterior and posterior columns results in spinal instability. Laminectomy may produce greater spinal instability and will convert a stable injury into a unstable one. The compression that exists in these injury is anterior and therefore posterior laminectomy do little more than produce spinal instability. The technique of open reduction and Harrington rod fixation of unstable fractures improved nursing care, shortened rehabilitation and was effective in maintaining fracture reduction and promoting bony healing. Between 1978 and 1980, thirteen consecutive patient with unstable fractures and fracture-dislocations of thoracolumbar spine were treated by open reduction and spinal fusion with Harrington rod fixation at the Department of Orthopaedic Surgery of the Han Gang and Kang Nam Sacred Heart Hospitals. The following results were obtained from analysis of the cases. 1. The reduction and stability after reduction with Hsrrington instrumentation was excellent. 2. Laminectomy produced greater spinal instability. 3. Early ambulation was possible and the period of hospitalization was shortened. 4. Neurological recovery from incomplete neural deficit was good but from complete paraplegia was less effective.

We report a case of cerebriform intradermal nevus. a cause of cutis verticis gyrata that clinically they resembled neurofibroma and revealed histopathologic finding consistent with intradermal nevus. The patient was a 6 year-old boy, who had a 17x18cm, soft, convoluted. pigmented mass over the parietal and occipital regions. The lesion had been present since birth and had been slowly increasing in size with convolution.

Postoperative colonoscopy is an effective tool for management of colonic adenomas. Authors analyzed the pattern of colonic adenomas detected during follow-up colonoscopy after colorectal cancer surgery and evaluated the characteristics of adenornas, risk groups, and effective fo1low-up schedule. Study group were 222 patients and colonoscopy was performed 389 times. Patterns of adenornas were analyzed by variables as age, sex, preoperative serum CEA level, location of primary colorectal cancer, Borrmann type, Duke's stage, histologic differentiation, DNA ploidy, recurrence and histology. Metachronous adenomas were detected in 79 patients(35.6%) and both metachronous and syachronous adenomas were observed in 29 cases(13.1%). High risk variables for adenomas were male, old age and presence of synchronous adenoma. There were 2 patients with maligant change of adenomas. Yearly follow-up by complete colonoscopy over 3 years or more is recommended and follow-up interval should be shortened in the high risk groups.

BACKGROUND AND OBJECTIVES: Herpes zoster(HZ) is a well known viral infection of the nervous system. HZ is associated with the neurologic complication. It may have been expected a change in the cerebrospinal fluid(CSF) of patients with HZ. The purpose of this paper is to present the correlation between CSF findings and neurologic complications in HZ. METHOD: The patients(n=75) with HZ were 31 male and 26 females, who were ranged in age from 15 to 79years(mean 53.4 years) admitted to department of Neurology of Chung Ang Gil General Hospital from June 1992 to May 1995. The patients were evaluated for the etiology, lesion distribution, and complications. CSF study was performed in 32 patients(male/female=20/12), whose age ranged from 16 to 79 years(means 51years) during 5 days to 10days after initial symptom onset. CSF findings were analyzed for their etiology, lesion distribution and complication. RESULTS: The CSF of 25 patients(78.1%) showed pleocytosis(5 to 49/mm3 in 10 patients, means, 62.1/mm3). 7 patients(12.3%) had meningitis symptoms, whose cell counts of CSF were more than 50/mm3(means 128.4/mm3) postherapeutic neuralgia was more common in elder patient than younger patients(p=0.005). Complications tended to correlate with the cell counts of CSF. There was no difference in CSF finding between cranial segmental involvements. CONCLUSION: We confirmed the pleocytosis in CSF of patients with HZ and suggest the development of complications in patients in patients with HZ tend to correlate with the cell counts of CSF.
