Dislocation of the elbow joint is so frequent an injury, and its treatment so standardized, that most of the recent orthopaedic study devoted to the subject has focused on neurovascular complication or recurrent dislocation. Some authors reported minimal period of disability and better range of extension after three to five days short-term immobilization in simple acute dislocation. We, authors, had analyzed clinically 17 cases of acute dislocation of elbow joint who were treated at orthopaedic department of Catholic Medical College from Jan., 1978 to Dec., 1981. The results obtained were as follows: 1. The most prevalent age were second and third decades (76.5%). Males predominated by a ratio of 13:4. 2. The major mode of injury was slip down accident (58.8%). All cases were acute simple dislocation without open wound. 3. Posterolateral, dislocations were 13 cases (76.5%) and posterior dislocations were 3 cases (17.6%). These two type of dislocation were 94.1% of all cases. No anterior dislocation was noted. 4. Four fractures of radial head and one fracture of lateral epicondyle of humerus were seen. Associated fractures were noted in 29.4% of all cases. 5. Severe complication was none except one recurrent habituai dislocation and limitation of elbow extension, averaging 10.5 degrees, 6. In 9 cases which were immobilized for 3 to 5 days had an average loss of extension of 6 degrees and an average of 7 weeks of disability. In 7 cases which were immobilized for 3 weeks had an average loss of extension of 18 degrees and an average of 18.3 weeks of disability. Therefore, immediate reduction and 3 to 5 dhys of immobililization is excellent treatment for uncomplicated dislocations.

In order to investigate the level of lead exposure of workers in litharge making industry and to evaluate how lead exposure, personal habit such as smoking and drinking affect the prevalence of lead related symptoms and other study variables, we investigate 114 workers(24 office workers and 90 lead exposed workers) in a litharge making industry. Study variables chosen were blood lead(PbB), zinc protoporphyrin in whole blood(ZPP), Hemoglobin(Hb), hematocrit (Hct), SGOT and SGPT. symptom questionnaires which had 15 lead exposure related symptoms were provided to all workers and filled up by themselves and reconfirmed by physician. The results obtained were as follows; 1. The mean value of PbB, ZPP and SGOT in lead exposed group were higher than those of non-exposed group, and there were no differences of means in other study variables. 2. The smoking and drinking rate of study subjects were 65.8% and 71.0% as a whole. Smoking rates were lower in non-exposed group than exposed group, but drinking rate were not. 3. There were no differences of mean values of study variables between smoker and non-smoker in non-exposed and exposed group, but there was a difference of mean value of SGOT between drinker and non-drinker in lead exposed group. 4. while the symptom prevalence of lead exposed group were higher in neuromuscular category than non-exposed group, those of non-exposed group were higher or same with exposed group in gastrointestinal and general symptom category. 5. The symptom prevalence of smoker were higher than non-smoker regardless of exposure. 6. The symptom prevalence of drinker were only higher in gastrointestinal symptom category than non-drinker. 7. In multiple stepwise regression analysis of lead related symptoms as dependent variable and blood lead, smoking habit, drinking habit and work duration as independent variables, drinking habit contributed to the gastrointestinal symptom category, whereas blood lead and smoking contributed to the neuromuscular symptom category. For the total symptoms work duration and smoking habit contributed significantly.

The use of osseointegrated implants is an accepted procedure for the treatment of Total, or partial edentulism and offers good predictability of long-term success. Osseointegration implies a firm and direct interlocking between vital bone and screw-shaped titanium implants. There should be not to interposed tissue between fixture and bone. This study was undertaken to assess the clinical condition, complication, and prosthodontic aftercare of different implant systems. One hundred fifty-nine patients treated with a total of 503 endosseous implants (364 Steri-oss threaded type, 69 Integral cylinder with HA coated type, 35 Steri-oss threaded with HA coated type, 21 Steri-oss cylinder with HA coated type and 14 3i implant type), Most of the implant were placed in type B and C bone quantity and type 2 and 3 bone quality according to Lekhorm and Zarb. The success rate of Steri-oss threaded type during healing and function was 92%, Steri-oss threaded type with hydroxyapatite coated was 91%, Steri-oss cylinder type with hydroxyapatite coated was 90%, Integral cylinder type with hydroxyapatite coated was 90% and 3i implant type was 93%. One hundred twenty-nine patients had been treated with implant prosthesis. 79 of these patients had received a fixed type prosthesis and 50 patients had received a removable type prosthesis. There were no differences between the implant systems with regard to age, gender. Failures were associated with poor bone quality, smaller implant sizes, a surgical installation technique and stress distribution when in function. Visual analgoue scales recorded as satisfied results functionally and esthetically, but 15% dissatified with chewing ability.

Lymphomatoid Granulomatosis*

Kerion celsi caused by Trichophyton(T.) rubrum is rare endemically and there has been no report of it in Korean literatures. We report a case of karion celsi caused by T. rubrum in a 71-year-old male, who showed anindurated, swollen, boggy mass exuding pus on the right parietal scalp for about 7 weeks. The colonies and microconidia were identified as T. rubrum by fungus culture in potato dextrose agar. After administration of itraconazole for 11 weeks, the lesion was healed and the regrowing of new hairs was observed.

STATEMENT OF PROBLEM: Recently, various all-ceramic crowns fabricated with CAD/CAM systems have come into wide use in dental clinic. However, there are only few domestic studies on CAD/CAM restorations. PURPOSE: Purpose of this study was to compare the fidelity (absolute marginal discrepancy and internal gap) between various cores fabricated with different CAD/CAM systems (Procera system, Lava system, Cerec inLab system) and conventional metal cast core. MATERIALS AND METHODS: 10 cores per each system were fabricated. The absolute marginal discrepancies were measured using measuring microscope and digital counter. The internal gaps were calculated using a silicone paste. The results were statistically analyzed using the one-way ANOVA test and Tukey's HSD test. RESULTS: Within the limits of this study the results were as follows. 1. The absolute marginal discrepancies were 32.5+/-3.7 micrometer for metal cast core, 72.2+/-7.0 micrometer for Procera core, 40.8+/-5.4 micrometer for Lava core, and 55.3+/-8.7 micrometer for Cerec inLab core. The internal gaps were 38.4+/-5.7 micrometer for metal cast core, 71.4+/-5.3 micrometer for Procera core, 45.9+/-7.3 micrometer for Lava core, and 51.8+/-6.2 micrometer for Cerec inLab core. 2. The fidelity of metal cast core showed the smallest gaps, followed by Lava core, Cerec inLab core, and Procera core. CONCLUSION: The fidelities of 4 core groups were all within the clinically acceptable range (120 micrometer).

We attempted to study the role of protein tyrosine kinase (PTK) and protein kinase C (PKC) in the cascade of phosphorylation of ribosomal protein S6 during differentiation of leukemic cells (HL-60, THP-1, and RWLeu-4). Neither activation nor inhibition of colony stimulating factor-1 (CSF-1) receptor's PTK activity with CSF-1 or genistein respectively affected the phosphorylation of S6. However, vanadate which is a protein tyrosine phosphatase (PTP) inhibitor showed enhancement of S6 phosphorylation. Dimethylsulfoxide which does not affect either PTK or PKC demonstrated no change in S6 phosphorylation. PKC activation by acute 12-0-tetradecanoyl phorbol-13-acetate (TPA) treatment induced monocytic differentiation and S6 phosphorylation. Surprisingly, the more prominent phosphorylation of S6 protein was observed in PKC-depleted cells by prolonged TPA treatment. Our results suggest that PTK/PTP play a lesser role in S6 phosphorylation of HL-60 cells than PKC does. In addition, two different mechanisms seem to be involved in TPA-induced S6 phosphorylation during HL-60 differentiation: PKC activation by acute TPA treatment and PKC depletion which may lead to the synthesis of some endogenous protein responsible for the differentiation by chronic TPA treatment.
