Lumbar spinal stenosis may be defined as any type of narrowing of the spinal canal, nerve root canals or intervertebral foramina. It may be local, segmental or generalized and may be caused by the encroachment of bone or soft tissue. The narrowing may involve the bony canal alone or the dural sac or both. Myelo-enhanced computerized tomography(MECT) has been accepted as especially useful diagnostic method for spinal steonsis after its application in the orthopedic fields. The goal of this study was to analyze the diagnostic accuracy and sensitivity of MECT and to determine the prevalance of stenosis in various regions of lumbar spine. During the period of 3 years, from January 1991 to December 1993, 40 cases of lumbar spinal stenosis were analyzed, all of whom took myelography, computerized tomography and surgical treatment. The results of the study were as follows: 1. The myelographic findings were, respectively, hourglass bilateral defect 15(37.5%), complete block 14(35%) and the unilateral focal defect 5(12.5%). 2. The most prevalent from of spinal stenosis was the combined central-lateral-foraminal stenosis(47.5%) and the degenerative change in the lumbar spine was the principal etiologic factor(55%) by Arnoldi classification. 3. The involved levels were as follows:1 level 18(45%), 2 level 16(40%) and 3 level 6(15%). And among single level, the most frequent level was L5-S1 intervertebral space(30%). The diagnostic accuracies according to operative finding and above results were 83% by myelography and 97.5% by MECT. The MECT showed absolutely superior to myelography or CT and it was especially useful in lateral stenosis and multi-level stenosis.

A clinical observation was made on 16 patients of penis carcinoma admitted to the Department of Urology, Catholic Medical College Hospital during the period from August, 1972 to July, 1982 and the following results were obtained. 1. The incidence of penis carcinoma was 0.4% of total inpatients of urologic department and 3.9% of genitourinary cancer. 2. Age distribution was from 43 to 78, showing highest incidence at 50-59 years. 3. Clinical findings were; mass 56%, Ulcer 44% and inguinal lymphadenopathy 44%. 4. Treatment were partial amputation in 18.8%, partial amputation with lymph node dissection in 43.8% and total amputation with lymph node dissection in 25%. 5. Of 11 cases in whom lymph node dissection were performed, 4 cases were positive for metastasis. Of 7 cases with palpable lymph nodes, 3 cases were positive for metastasis. In 4 cases having lymph node dissection when lymph nodes were not palpable, 1 case was positive for metastasis.

Albino rats fed on crops from endemic and non-endemic districts of Ke-shan desease, were used in this experiment, which was studied by 85Zn tracer metabolic method after 8 weeks feeding. Uptake of 85Zn (ZnCl2) by blood, heart, liver, kidneys and brown adipose tissue were determined at 24 and 72 hours after injection of this tracer respectively, and its distribution was thoroughly examined. The results revealed that the uptake of 8aZn was higher in the groups fed on crops from endemic districts, particularly significant in liver, kidneys and brown adipose tissue. This may reflect the lacking or deficiency of zinc in the bodies.The regular differences of 85Zn between two groups were certainly related to the crops produced from endemic or aon-endemic districts. In other words, there should be some differences between crops from endemic and non-endemic areas. Thus more attention should be paid to the factors in endemic crops, which induced lacking or deficiency of zinc in the experimental animal and to its relationship with etiology of Keshan disease.

Ankylosing spondylitis is a chronic inflammatory disease which most frequently affects the sacro-iliac joints of young men, and also the synovial joints of the whole spine. Bony fusion of these joints and ossification along the longitudinal ligaments lead to total immobility of the vertebrae. Sixty-two cases of ankylosing spondylitis treated at the Severance Hospital from June 1980 to June 1986 were analysed clinically and the followings were obtained. 1. The average age was 38 years and the sex ratio between the male and the female was 58: 4(Male=94%). 2. The most frequent location of pain was low back (32%), and the pain was usually bilateral (81%). 3. The main stiff regions were the hip joint (35%) and the lumbar spine (27%). 4. The most frequent joint affected was the hip (44%), and the extraarticular manifestations were pleuropulmonary disease (29%), gastrointestinal disorder (15%), iritis (10%), etc. 5. The characteristic X-ray findings were sacro-iliac changes (72%), facet joint blurring (53%), and syndesmophyte (37%). 6. Laborstory findings showed increased ESR (85%), positive HLA B-27 (97%), negative rheumatoid factor (94%), and the serum immunoglobulins snd complements were not decreased.

Multiple studies have established that mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) exhibits reversible diffusion restriction in the white matter, including the splenium. There have been a few previous reports of the change in fractional anisotropy (FA) of MERS cases. Herein, we report the longitudinal changes in axial and radial diffusivity (AD and RD), and FA in a 15-year-old boy patient with MERS. Our case demonstrated that a MERS lesion had a significant drop of AD in the early period and gradual recovery. On the contrary, RD did not show any significant change.

Objective To study on the CDKN2/P16 gene in primary osteosarcoma.Method By using molecular biological methods that inclued genome DNA extraction from paraffined tissue and PCR SSCP analysis technique, we studied alternations of CDKN2/P16 gene in 25 primary osteosarcomas.Results (1)The deletions frequency in differentiation degree of osteosarcomas was① bone brood cell, 16.7% ;② cartilage brood cell,12.5% ;③ Fiber brood cell:20% ,(P >0.05).(2)The deletion frequency in male patients was 17.6% , female patients 12.5% ,(P >0.05).(3)In early metastatic osteosarcomas the deletion rate was 33.3% ,which was significantly higher than that of the control group with the rate of 10.5% (P< 0.05).(4)The deletion rate was 16% and the mutations were not found.Conclusion (1)The deletion rate was 16% and the mutations were not found.This suggests that the deletions of CDKN2/P16 gene were closely related to the genesis of primary osteosarcoma and that the main type of the alternation of CDKN2/P16 gene was deletion.(2)In early metastatic osteosaarcomas the deletion rate was 33.3% , which was significantly higher than that of the control group with the rate of 10.5% .This indicates to great extend that the deletions of CDKN2/P16 gene were closely related to the metastatic ability.(3)The deletions frequency had no significant relationship with differentiation degree of osteosarcomas, so was with the sex of the patient.
