This is to present 44 cases of hip fractures, of these 28 being fractures of femoral neck and the remainder, intertrochanteric, which were treated at the Department of Orthopedic Surgery, Seoul National University Hospital for four years and 8 months from Jan. 1965 to Aug. 1969. 1. There were 33 males. and 11 females in the series. 26 cases(59.1) were over 51 years of age. 2. The femoral neck fractures were treated by means of Smith Petersen nailing in 16 cases, modified Girdlestone hip arthroplasty in 3 cases, Austin-Moore hip prosthesis in 6 cases and other methods in 3 cases. 3. Modified Girdlestone hip arthroplasty could be a treatment of choice for femoral neck fracture requiring hip arthroplasty for those unsuitable for extensive surgery. 4. The intertrochanteric fractures of femur except for 3 unstable fractures were treated successfully with the Smith-Petersen nail and plate, following anatomical reduction of fracture. In 3 unstable fractures, satisfactory stabilization and internal fixation was obtained by the method of medial displacement of proximal part of distal fragment of fracture.

Five cases of the spinal tuberculosis with severe kyphosis and paraplegia were treated with radical surgery at the Department of Orthopedic Surgery, Seoul National University Hospital. All the cases were involved at the thoracic spine and kyphosis were ranged 100 through 150 degrees. Severe fixed chest deformity and impaired pulmonary function were observed. By thoracotomy, aorta was seen to be adherent to the surrounding tissue and this was separated from the verterbral lesion with meticulous procedure. The focus was curetted radically exposing spinal cord which was decompressed with anterior transposition. Then the spine was stabilized with anterior interbody fusion. Postoperative intensive pulmonary care and antituberculous therapy are imperative for the good result. Spinal tuberculosi with severe kyphosis and paraplegia could be benefited with the radical surgery by the experienced surgeon.

Aurthors have treated 77 cases of acute supp rative osteomyelitis since January 1972 until December 1979. Among them 69 patients had surgical treatment while 8 cases had antibiotic therapy only. 42 patients out of 69 surgically treated cases had fenestration operation, while 27 cases had multiple drilling operation to evacuate the bony abscess. In 15 cases Turkels bone biopsy needle was used to decompress the infected bones, and by It the abscess could be very effectively evacuated. After decompression with a Turkel needle by placing a small calibered polyethylene tube Into the lesion, the lesion was continuously irrigated with antibiotics solution. This procedure has proved to be very effective and a successful one which can easily be practised as an office procedure in the very poor and needy cases. Also when patients are seriously ill and/or other extensive surgery is not feasible, this simple procedure can easily be practised without hazard, Good end results without sequellae were abtained when early decompression with massive antiblotic therapy was instituted even by Turkel needle drainage.

The phosphorylation and dephosphorylation of proteins on tyrosyl residues are key regulatory mechanisms of cell growth and signal transduction and are controlled by opposing activities of protein tyrosine kinases and phosphotyrosyl phosphatases (PTPs). We have previously cloned and characterized a nontransmembrane chicken protein tyrosine phosphatase 1 (CPTP1) similar to human placental PTP1B (HPTP1B). CPTP1 contains several phosphorylation sequence motifs (S/T-X-X-D/E) for casein kinase II (CKII), [(I > E > V)-Y-(E > G)-(E > D > P > N)-(I/V > L)] for p56(1ck), and (P-E-S-P) for MAP kinase. To examine whether phosphatase activity of CPTP1 could be controlled by phosphorylation, CPTP1 and HPTP1B fusion proteins purified from E. coil were subjected to the in vitro phosphorylation by CKII. Phosphoamino acid analysis revealed that CPTP1 was phosphorylated on both serine and threonine residues by CKII in vitro. In addition, the degree of the phosphorylation of CPTP1 by CKII was shown to be five times higher than that of HPTP1B. Phosphorylation on both serine and threonine residues of CPTP1 in vitro results in an inhibition of its phosphatase activity. This result suggests that phosphorylation of CPTP1 and HPTP1B by CKII might be implicated in the regulation of their catalytic activities in the cell.

PURPOSE: To assess the diagnostic efficacy of macular and peripapillary retinal thickness measurements for the staging of diabetic retinopathy (DR) and the prediction of disease progression. METHODS: In this prospective study, 149 diabetic patients (149 eyes) and 50 non-diabetic control subjects were included. Baseline optical coherence tomography was employed to measure retinal thickness in the macula (horizontal, vertical, and central) and the peripapillary zone (superior, inferior, nasal, and concentric to the optic disc). Seven baseline parameters were correlated with the DR stages identified by fluorescein angiography. Baseline retinal thickness was compared between groups of patients requiring panretinal photocoagulation (PRP) within 6 months (PRP group) and patients not requiring PRP (No-PRP group). RESULTS: Macular and peripapillary retinal thicknesses in diabetic subjects were significantly greater than that in normal controls (p<0.05). All retinal thickness parameters, and particularly peripapillary circular scans, tended to increase with increasing DR severity (p<0.05). The baseline thicknesses of the peripapillary circular scans were greater in the PRP group than in the no-PRP group (p<0.05). CONCLUSIONS: Peripapillary retinal thickness may prove to be a useful criterion for DR severity and may also serve as an indicator of disease progression.

PURPOSE: The aim of this study was to introduce a method of obtaining the oscillation graphs of the dental x-ray tube heads relative to time using an accelerometer. MATERIALS AND METHODS: An Accelerometer, Piezotron type 8704B25 (Kistler Instrument Co., Amherst, NY, USA) was utilized to measure the horizontal oscillation of the x-ray tube head immediately after positioning the tube head for an intraoral radiograph. The signal from the sensor was transferred to a dynamic signal analyzer, which displayed the magnitude of the acceleration on the Y-axis and time lapse on the X-axis. The horizontal oscillation of the tube head was measured relative to time, and the settling time was also determined on the basis of the acceleration graphs for 6 wall type, 5 floor-fixed type, and 4 mobile type dental x-ray machines. RESULTS: The oscillation graphs showed that tube head movement decreased rapidly over time. The settling time varied with x-ray machine types. Wall-type x-ray machines had a settling time of up to 6 seconds, 5 seconds for fixed floor-types, and 11 seconds for the mobile-types. CONCLUSION: Using an accelerometer, we obtained the oscillation graphs of the dental x-ray tube head relative to time. The oscillation graph with time can guide the operator to decide upon the optimum exposure moment after xray tube head positioning for better radiographic resolution.

Clinical study was made on 675 cases of newborn infant who were born by vacuum extraction during the period of January 1971 through December 1975. The results obtained were as follows: 1. The incidence of vacuum extraction among 4,153 deliveries was 16.3% and there was a slight decreasing tendency annually. 2. The highest maternal age incidence was 26 to 30 years of age and vacuum extraction rate was higher in primipara (75.6%) than multipara (24.4%). 3. There were more male (62.2%) than female (37.8%) and 91.6% of the infants were born with 40 to 41 weeks of gestational age and 89.3% of in infants weighing between 2,500 to 4,000g at birth. 4. The majority (774.6%) of the newborn infant had good (10) Apgar score at one minute and only 5.6%had score below 7. 5. The major complication was head injuries and which were 91.1% of increased size of caput succedaneum, 3.1% of scalp abrasion, 3.4% of cephalhematoma, 0.3% of intracranial hemorrhage, and 0.3% of linear skull fracture, Visible jaundice was found in 9.0% of the newborn infants among those 80.3% showed total serum bilirubin level of 15mg/100ml or less, 19.7% showed 20mg/100ml or more but there was no case of severe jaundice required exchange transfusion.
