So many modalities have been suggested for the treatment of servere pain and ankylosis of the elbow with destruction of the articular surfaces. Among them, two major methods which have been widely used are resection arthroplasty and prosthetic replacement arthroplasty. However prosthetic replacement arthroplasty has some problems. Its indications are limited in the elderly inactive subjects. And there have been many kinds of complications including loosening and infection. Also, resection arthroplasty in now rarely indicated due to severe instability. From July 1980 to July 1987, we tried distraction arthroplasty in 8 cases of elbow with severe destruction of its articular surfaces, mainly in the young active persons. The average follow-up period was 45 months. The effect of distraction arthroplasty on relief of pain was not remarkable. The average increase in ROM, including that of one reankylosed elbow, was 51 ±22 degrees in flexion-extension and 48 ±23 degrees in pronstion-supinstion. No deep wound infection and instability which was main complication of resection arthroplasty were observed with our method of distraction arthroplasty. On the basis of functional results, the the results were excellent in 4, good in 1, fair in 2 and poor in 1 cases. In conclusion, distraction arthroplasty of the elbow can be one of the of effective methods reconstruction for the young active patients with the destruction of the elbow, if they are intelligent and motivated.

From March 1988 to August 1989, 51 knees with clinically suspected meniscus injuries were examined by both MRI and arthroscopy and compared their findings prospectively on the basis of arthroscopic findings to determine the accuracy of MRI in detecting meniscus injury of the knee. We used 2.0 tesla superconducting magnet imager(Spectro-20000, GoldStar, Korea) to obtain MR imaging. Our protocol for imaging was producing Tl sagittal images by spinecho technique and T2 coronal images by gradient echo technique, interleaved at 4mm continuously while the patient's knee was in 8–10 degrees of external rotation and surface coil was placed posteriorly to the knee in supine position. We grouped and correlated the findings of MRI with the arthroscopic findings. With this noninvasive MRI, we could obtain multiplanar, high quality images without compliations. Compared with the arthroscopic findings, MRI resulted in a high diagnostic accuracy of 96 and 86 percent for the medial and lateral meniscus, respectively. And it aided in optimal surgical planning for the clinically suspected meniscus injuries.

BACKGROUND: Mechanisms of secondary injury (post-ischemic injury) in the central nervous system have cently reported in a vast of amount of experiments. Among many factors which give rise to post-ischemic neuronal damage, glial deterioration probably mediated by calcium paradox, could be another of the aggravating deleterious factars to the already ischemic neurophil. METHODS: Here we have designed experiment to investigate calcium paradox in astroglial cell line, humsn asttocytoma U1242MG. Intracellular calcium alterations in experimental cells were monitored by using calcium indicating dye fura-2 and epifluorescent photometry system. RESULTS: Intracellular free calcium changes during reperfusion phase after exposure to low calcium led to a prampt increase in intracellular calcium level after 10 and 30 minutes. The way of calcium entry during the reperfusion phase was mediated by the revase mode of Na+/Ca(2+) exchanger. Cells that had a reduction of reperfusate calcium to 10 uM increased cell viability. Also we observed an inverse relationship between major enzymatic activity in the astrocytoma cells (i.e., glutamine synthetase activity) and the duration of reperfusion in the the same protocols. CONCLUSIONS: A relatively small amount of intracellular calcium increase by the reverse mode of Na+/Ca(2+) exchanger during the reperfusion period is related to a limitation of enzyme activity and viability 24 hours later.

This study was undertaken to evaluate the status of human paragonimiasis in Kang Hwa Gun, Kyunggi Do, Korea from March 1973 to October 1975 by the use of intradermal screening test with Veronal buffered saline antigen. A total number of 7,352 (male 3,936; female 3,4l6) consisting of 3,447 primary school children, 2,689 middle school students, l,008 high school students of 9 Myuns out of 13 Myuns of this County and 208 residents of all age group in Kilgeong-Ri, Yangdo Myun were examined by the intradermal test with Paragonimus antigen. In order to detect Paragonimus egg, the sputum and the stool examinations were undertaken on the residents in Kilgeong-Ri. The infestation rate of crayfish with Paragonimus metacercaria was also examined in Konneung and Jeongha village in Kilgeong-Ri. The following results were obtained in this survey: As a whole, 16.6 per cent of the examiners showed positive reaction with sexual difference of 16.1% in male and 14.8 per cent in female. In age groups, the highest positive rate showed in middle school age group (17.1 per cent) than primary school (14.0 per cent) and high school age group (11.4 per cent). In regional differences of positive rates, the highest rate (28.4 per cent) showed at Yangdo Myun followed by Kilsang Myun (27.0 per cent), Hwado Myun (25.0 per cent), and Naega Myun(20.8 per cent). In the result of 208 residents Kilgeong-Ri, the positive of 36.1 per cent in male and 20.2 per cent in female. The highest positive rate showed in 10 to 19 age group (41.5 per cent). Among the residents in Kilgeong-Ri, Paragonimus eggs were detected in 11 residents by the sputum and the stool examinations. The infestation rate of crayfsh with Paragonimus metacercariae was 100 per cent (41 out of 41 crayfishes) in Konneung village, and 84.6 per cent (9 out of 13 crayfishes) in Jeongha village, Kilgeong-Ri The fluctuation of the infection rate of crayfish with Paragonimus metacercariae was decreased in Konneung village in 2 years after the treatment with Bilevon against 10 paragonimiasis patients.
