At "Keumjung-gul" site, bones of more than 153 persons are excavated in October 1995. They were interred in Autumn of 1950 during Korean War. Among them, 70 skulls were examined in morphological method and DNA test for sex determination. With PCR amplification of amelogenin, 60 skulls were proved male, 9; female, 1; not amplified. Result with Y27H39LR, SRY and alphoid repeats were not satisfactory. The morphologic determination for sex were made maily by (1) prominence of the supercilliary arch, (2) prominence of the external occipital protuberance and crest, (3) size and shape of the mastoid process. The concurrence rate between two examiner, and between two morphologic result and DNA result were low (<70%), largely because of the subjectivity of morphologic trait and the paucity of experiences.

Total 40 cases of serial bone scans with Tc99-m-MDP performed on less than 24 hour, 2nd day, 3rd day, 5th day, 1 week, 4 week, 12 week and 1 year respectively after fractures in tibia were analysed. All 5 cases of bone scans performed within 24 hour after injury showed increase in generalized tracer uptake and 3 cases of them(60%) showed localized increase in tracer uptake at the fracture sites. The earliest bone sean performed 9 hour after injury showed generally and locally increased uptake at the fracture sites. All 5 cases of bone scan performed 1 year after injury sinowed localized increased uptake at the fracture sites and 2 cases of them (40%) showed generalized increase in tracer uptake. Bone scans performed 12 week after injury showed the most outstanding increase in generalized and localized tracer uptake. Bone scans performed 1 year after injury showed decreased amount of generalized increase in tracer uptake (but more increased uptake than normal) but the localized increase in traccer uptake at the fracture sites was observed persistently. More study should be needed to clarify the corelationship between the presence of cold spots during the fracture healing and the union of the fractures. It is difficult to differentiate the old fractures to fresh fractures with the bone scans performed within 1 year because of persistent increase in tracer uptake to 1 year after fracture.

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.

BACKGROUND: The purpose of this study was to discover ways to screen urine culture specimens through Gram stains, urine stick analyses and microscopic examinations for the laboratory cost saving. METHODS: One hundred and fifty-eight urine specimens for culture were included. Fifty uL of urine were inoculated onto one well each of 10-well slide, dried on the hot plate, and Gram-stained. The results combined with routine urinalyses including urine nitrite and leukocyte esterase, and pyuria, were compared with the routine culture results. RESULTS: The screening of bacteriuria by Gram stains, urinalyses and microscopic examinations revealed the high sensitivity (91.9%) and negative predictive value(95.5%) with cost saving of 41.8% of inoculating media. Not considering the Gram stains, the screening revealed 83.8% sensitivity and 92.5% negative predictive value, even if the cost saving of inoculating media were as high as 50.1%. CONCLUSION: It was demonstrated that it was sensitive and economic and produced rapid preliminary results to screen bacteriuria by the Gram stains combined with urinalyses and microscopic examinations.

The chondrogenic potential of free autogenous periosteal grafts for osteochondral defects was investigated at the Department of Orthopaedic Surgery, Yonsei University, Wonju College of Medicine. Five millimeter diameter of circular full-thickness defects were made in patellar groove of both femur in 64 adolescent rabbits and the rectangular periostei, prepared from the proximal tibiae, were placed over the defects of patellar groove and sutured(cambium layer, facing joint surface) and the rabbits were allowed to move actively. A serial gross and histologic examinations of neochondrogenesis were done during 8 weeks. The results were as follows. l. At 2 weeks after operation, neochondrogenesis was hardly seen either in the graft group or in the control group. The defects were partially filled with some fibrous tissue. 2. After 6 weeks of operation, all defects in the graft group(postop 6 weeks and 8 weeks) were filled with hyaline cartilage cells but only 38% (postop 6 weeks) and 44% (postop 8 weeks) of the control group were filled with hyaline cartilage cells. 3. The cartilages, formed at 6 and 8 weeks, were more mature and better than those formed at 4 weeks. 4. The newly formed hyaline cartilage of the graft group filled the defect earlier and were better than those of the control group. 5. The chondrocytes in the newly formed tissue were originated from the cambium layer of periosteal grafts. 6. Free autogenous periosteal grafts can repair a full-thickness defect in a joint surface by producing tissue that resembles articular cartilage grossly and histologically.

BACKGROUND: Newly developed alpha-, beta-receptor blocker, Amosulalol HCI(YM-09538) was evaluated for its hypotensive efficacy, safety and usefulness in patients with mild to moderate essential hypertension. METHODS: Thirty patients of essential hypertension(male 8, female 22), mean age 55 years were included for the study. Amosulalol HCI was administered 20-60mg daily for 10 weeks and initial starting dose was 10mg twice daily and dose was increased 40mg and 60mg daily in cases of insatisfactory hypotensive effect ever 2 weeks interval. Patients were evaluated every two weeks on blood pressure, pulse rate, improvement of subjective symptoms and side effects. Laboratory examinations were carried out routinely in principle two times before trial and after completion of study. RESULTS: Blood pressure began to fall significantly after tow weeks of administration and changed from initial 172.4mmHg of systolic pressure to final 149.3mmHg and from 104.7mmHg of diastolic pressure to final 92.5mmHg. The response rates were marked fall in 30%, satisfactory fall in 40%, thus overall hypotensive effect was observed in 70%. Pulse rate decreased slightiy but significantly from 4 weeks of administration. Improvement of subjective symptoms were observed in 7 cases out of 12 cases and no significant side effects were observedd except of two mild transitory cases of polyuria and indigestion. Laboratory examination also did not show any significant changes before and after medication. CONCLUSION: The daily administration fo 20-60mg of Amosulalol HCI to moderate essectial hypertension seems to be effective and safe with clinical usefulness.

OBJECTIVE: To assess the relationship between vaginal cytology and bone mineral density in postmenopausal women. METHODS: In 93 postmenopausal women, vaginal cytology smears were taken for maturation index, serum estradiol level and bone mineral density were also taken. the percentage of each cell type found By vaginal cytology was multiplied to its specific value:superficial cells, 1.0; intermediate cell, 0.6; parabasal cell, 0.2 and modified to maturation value. Bone mineral density was measured at lumbar spine using DEXA. RESULTS: The mean bone mineral density was 0.88+/-0.14g/cm2. Mean maturation value was 50.53+/-20.74 and it was related with age and bone mineral density. CONCLUSION: Maturation value of vaginal epithelial cell represents the influence of estrogen on bone mineral density.
