From Mar. 1984 to Mar. 1994, we carried out 18 revision operations in patients who received Girdlestone operation due to the infection of hip was 7 cases, tuberculosis of hip was 3 cases, deep infections after implant insertion of hip were 5 cases, and pyogenic sequela was 1 case. The mean conversion period was 27 months. The leg length discrepancy, range of motion of hip, and Trendelenberg gait were examined before and after conversion to a total hip arthroplasty. The last functional state was evaluated and radiological examination was performed. In summary and Conclusion; 1. The time of performing revision hip arthroplasty was assessed by clinical, radiologic and laboratory finding, and the average time of conversion to total hip arthroplasty was 7.6 months after Girdlestone operation. 2. There was no case of recurrence of infection after revision operations. 3. At last follow-up after revision hip arthroplasty, the mean Harris Hip Score was 87.2(69.6–92.2) point. 4. Six patients had no pain, 8 patients had mild pain, and 2 patients had moderate pain. Nine patients were able to walk without ambulatory aids and 7 patients needed crutch or cane for walking. 5. At the time of revision hip arthroplasty, the average shortening of the resected limb was 4.2cm(1.6–7.3cm), and after revision operation, the average shortening was reduced to 1.2cm(0.8–2.2cm) 6. The technical difficulties, such as increased bleeding, bone deficiency, scar tissue formation, and limb shortening were encountered in all cases. 7. The peroneal nerve injury was developed in one patient who had conversion hip arthroplasty at 13 months after Girdlestone operation.

This study intended to obtain an useful information on the prevalence of subjective symptoms, and to clarify the interrelationships between blood lead and lead related symptoms in low level lead exposure. The 93 male workers exposed to lead and 56 male nonexposed workers were examined for their blood lead (PBB), Zinc-protoporphy (ZPP), hemoglobin (HB) and personal history, and completed 15 questionnaires related to symptoms of lead absorption; also measured lead concentration in air (PBA) in the workplace. The results obtained were as follow; 1. The means of blood lead (PBB), blood ZPP and hemoglobin (HB) among workers exposed to lead were 26.1+/-8.8 microgram/dl, 28.3+/-26.0 microgram/dl and 16.2+/-1.2g/dl; whereas those of nonexposed workers were 18.7+/-5.1 microgram/dl, 20.6+/-8.7 microgram/dl and 17.3+/-1.1g/dl. The means of above three indicies between two groups showed significant difference statistically (p<0.05). 2. The means of blood lead (PBB), blood ZPP and hemoglobin of workers exposed to different lead concentration in air were as follows; When it was below 25 microgram/m3 , the indices were 24.7+/-79, 26.1+/-26.8 microgram/dl and 16.4+/-1.1 g/dl respectively; These indices were 27.1+/-8.5, 23.9+/-10.92 /dl and 16.2+/-1.3 g/dl when the lead concentration in air was 25~50 microgram/m3; and they were 3.4+/-9.3, 42.3+/-31.3 microgram/dl and 15.5+/-1.2 g/dl when the concentration of lead was above 50 microgram/m3. Although there were statistical difference in blood lead and hemoglobin among three different lead concentration in air, there was no statistical difference of blood ZPP among the three groups with different exposure levels (p>0.05). 3. The most frequently by complained symptom was "Generalized weakness and fatigue", and fewest symptom was "Intermittent pains in abdomen". 4. Only two symptoms out of fifteen symptoms checked by themselves revealed significant difference between exposed and nonexposed groups. These were "Intermittent pains of abdomen" and "Joint pain or arthralgia" (p<0.05). No positive correlation was found between the levels of blood lead and symptom groups categorized as gastrointestinal, neuromuscular and constitutional symptoms. 5. Blood lead (r=0.3995) and ZPP (r=0.2837) showed statistically significant correlation with mean lead concentration in air, whereas correlations were not demonstrated between blood lead and lead related symptoms or blood ZPP and lead related symptoms. 6. Blood lead (PBB) and ZPP showed association (r=0.2466) and the equation PBB=23.75+0.0842 ZPP was derived. 7. On stepwise multiple regression, using blood lead level as a dependent variable and ZPP, hemoglobin (HB), age, work duration (WD) and symptom prevalence as a independent variables, only ZPP significantly contributed a lot to blood lead level. 8. While the ZPP measurement was found to be a good indicator in evaluating health effect of lead absorption in low level lead exposure, lead related symptoms were not sensitive enough to evaluate of lead absorption in low level exposure.

Many researchers report that the measurement of urine calcium concentration during antenatal period is helpful in prediction of having preeclampsia,but some don`t. The purpose of this clinical study is to evaluate the relationship of low calcium level in urine and the develpoment of preeclampsia, and effects of other variables. 24hour urine were collected and measured for the concentration of calcium and creatinine from 769 pregnant women who visited our department of obstetrics at Young-Dong Severeance hospital, Yonsei university medical college for antenatal care from March 1, 1993 to May 31, 1996. One group of 41 women developed preeclampsia and the other didn`t. There were no diffrences in ages and gestational age at urine collection between two groups, but a group with preeclampsia had an increased mean arterial blood pressure. There were signiificant difference in calcium concentration in urine and ratios of concentration of calcium and creatinine from urine collected between gestational ages of 25 weeks and 32 weeks and also in those women younger than 25 years old and their first pregnancy. Our study suggests that the measure ment of calcium level and ratios of urine calcium concentration and creatinine concentration at gestational ages between 25 weeks and 32 weeks in women younger than 25 year old with their first pregnancy is quite helpful inpredicting the develpoment of preeclampsia.

7.163 Cases of Decompression Sickness Among Korean Divers.
Korean Journal of Occupational and Environmental Medicine 1994;6(2):364-376
This study was performed to obtain an useful and basic information of the decompression sickness (DCS) among Korean divers. The medical records of 163 cases of Korean civilian diver, who were diagnosed as DES and received recompression therapy according to U.S. Navy Standard Recompression Treatment Table at Ocean & Underwater Medical Research & Training Center of ROK Navy, for 10 years from Jan. 1983 to Dec.1992. The total of 163 cases of DCS were catagorized into 2 groups as Type I DCS and Type II DGS group. The major results obtained were as follows: 1. 70.5% of total cases were classified as type II DCS, and the ratio of type I to type II DCS was 1'2.5 and the ratio of male to female of DCS cases was about 4:1. 2. About one third of cases occurred in May and June, and 38.7% of cases occurred at Chung-mu and Chin-hae in Kyung-nam province, the Southern Coast of Korean Peninsula. 3. Among the type II DGS group, 85.2% occured in diving for harpshell, and 85.2% with hookah diving gear. 4. There were no cases following the decompression procedure such as well known U.S. Navy's, and 86.7% of cases did not follow the any kinds of decompression procedure for preventing DCS and most of dives were conducted repetitively with 4.2 times on an average. 5. The mean depth between type I(27.3m) and type 11 DCS group(33.3m) showed significant difference statistically (p<0.01) , but both frequences of repetitive dives and bottom times between two groups were not statistically significant (p>0.05) . 6. The rate of symptoms appeared on surfacing and within 10 min. after surfacing of type I and type II DCS were 40.0% and 70.5%, respectively. And 80.9% of type I and 92.2% of type II DCS group were aware of dysbaric symptoms within the first hour after surfacing. 7. The most frequent symptoms and its percentages were "Both limb pain (37.6%) ",Joint pain(27.1%)., and "Scapular pain(22.9%)" in type I DCS group, and "Limb weakness or paralysis (68.7%)" , "Respiratory chokes(27.8%)" and "Bladder dysfunction(22.2%)"intypellDCSgroup. . 8. Among the type II DCS group, 54.8% attempted inwater recompression as a primary management, but 54.2% of type I DCS group did not take any kinds of therapeutic measure after onset of dysharic symptoms till commencing recompression treatment. 9. Recompression treatment was delayed 126.9 hours in type I and 89.7 hours in type II DCS group on an average, and the cases of DCS, who delayed more than two days till visiting the recompression facility, were occupied 52.1% in type I and 29.6% in type II DCS group. 10. Among the total cases, 32.6% were experienced one more of dysbaric symptoms in the past.

PURPOSE: Mucinous colorectal cancers have a poorer prognosis than which colorectal cancer produce low amount of mucin, but the exact mechanism is not well understood. The present study was undertaken to elucidate the exact mechanism of invasion and metastasis of high mucin producing colon cancer cells using mucin glycosylation inhibitor, benzyl-alpha-N-acetylgalactosamine. MATERIALS AND METHODS: To evaluate the effect of glycosylated mucin on invasion and metastasis, in vitro invasion, metalloproteinases (MMPs) activity, cell-matrix protein binding, cell-cell aggregation, as well as endothelial leukocyte adhesion molecule (ELAM-1) binding and cell surface expression of various mucin related antigens were analyzed. RESULTS: MMPs activity in conditioned medium and invasion of ECM-coated porous filters by benzyl-alpha-GalNAc treated HM7 cells were decreased. There was no difference between control and treated HM7 cells in terms of matrix protein binding assay, but treated HM7 cells showed higher homotypic cell adhesion. The binding activity of treated HM7 cells to ELAM-1 was significantly decreased and fixed cell binding of MoAb SNH-3, 19-9 (specific for sialyl-Lewis X and sialyl-Lewis A) were also significantly decreased. CONCLUSION: These results suggest that glycosylated mucin modulates ELAM-1 binding, MMPs activity and homotypic cell adhesion, therefore enhance invasive and metastatic properties of human colon cancer cells.

BACKGROUND: This study aims at making a survey on health care service providers' cultural competence and making an appraisal of Chinese medical tourists on service quality, health care service providers' cultural competence, perceived value, and satisfaction. METHODS: The data was collected from August until November, 2014 and 150 health care service providers and 65 Chinese medical tourists from 12 medical institutions in Daegu were enrolled in analysis. RESULTS: The results showed that health care service provider's knowledge on Chinese culture was very low with 33.5% of correct answer. Health care service providers were found to get 3.82 point on a 5 point-scale in cultural perception, 3.53 points in cultural sensitivity, and 2.85 points in cultural skills. Chinese medical tourists were analyzed to give 4.08 points on a 5-point scale to satisfaction on health care service, followed by 4.01 points to health care service quality, 4.00 points to perceived value of health care service, and last 3.85 points to a health care service providers' cultural skills. However, there was a difference in points in cultural skills between health care service providers and Chinese medical tourists. Chinese medical tourists' satisfaction with health care service in Daegu was found to be comparatively high, but in relation to satisfaction with communication, it was found to be relatively low. CONCLUSION: Through this research, health care service providers' knowledge level of Chinese culture and cultural skills were low while they seemed to take a half-hearted attitude towards educational experience for building up cultural competence and foreign patient service response.

PURPOSE: Joubert syndrome presents neonatal respiratory abnormalities and other clinical manifestations. Pathologically the patients show hypoplasia or agenesis of cerebellar vermis and other intracranial anomalies. Our purpose is to evaluate the clinical manifestations and MR findings of Joubert syndrome. MATERIALS AND METHODS: Among the patients presenting with clinical stigmata of Joubert syndrome and agenesis of vermis on MR imaging, eight patients who did not satisfied the criteria of Dandy-Walker malformation, tectocerebellar dysraphia and rhombencephalosynapsis were selected. MR findings and clinical manifestation were analyzed. RESULTS: On MR imaging, agenesis of the cerebellar vermis (all cases), hypoplasia of the cerebellar peduncle (6cases), fourth ventricular contour deformity(6cases), tentorial elevation (4cases), deformity of the lateral ventricles (4cases), dysgenesis of the straight sinus (3cases) were demonstrated. Other findings were abnormalities of corpus callosum (3cases), falx anomalies (3 cases), occipital encephalomeningocele (2 cases) and fluid collection in posterior cranial fossa (2cases). Clinical manifestations were developmental delay (5cases), abnormal eyeball movement (3cases), hypotonia (2 cases), neonatal rerspiratoy abnormality (2cases), etc. CONCLUSION: Joubert syndrome showed various clinical manifestations and intracranial anomalies. MR imaging is an useful modality in detection of the cerebellar vermian agenesis and other anomalies of the patients.
