Habitual snoring is common among males, especially among those who are overweight, and gets worse with the age. Snoring Is related to physical obstruction of breathing during sleep. This obstruction occurs when the palatal muscles, uvula muscles, and sometimes tonsiles relax during deep sleep and acts as vibrators. We have treated, with laser assisted uvulopalatoplasty(LAUP), twenty patients who suffer from snoring. CO2 laser was used and approximately I5-30 minutes of operation time was required. There were no singnificant complications, such as bleeding and asphyxia, in the 20 patients treated with LAUP. Results observed in the short term showed that 90% of the patients treated with LAUP considered thems to be essentially improved. Two patients developed scars at the posterior pillars. LAUP is a relatively simple and safe method which is performed at the hospital on an outpatient basis under local anesthesia.

Author take off the pelvic bone from the cadaver and made the accruate reconstructed the pelvic bone as well as normal bone. Then author setted the pelvic bone into the specialized acrylic globe as the normal person erect position. For the acetabular posterior wall, projected the radiologic beam from the 0°to 45°cephalad direction and then pelvic bone rotated internally 0°~45°, each section is 5°. For acetabular anterior wall, projected the radiologic beam from 0° to 45° caudal direction and pelvic bone rotated externally 0°~45°, each section is 5° too. From the pelvic bone experiments, author get on the good radiologic angle for acetabular anterior and posterior wall. Ane then make the radiologic projection for normal person as the pelvic experiment. In pelvic bone model experiment, For acetabular anterior wall and anterior colum, external rotation 20°~30° caudal tilting 30°~45° angle projection has good visualization. For acetabular posterior wall and posterior column (including anterior column partially), internal rotation 15°~20° cephalad tilting 15°~30°angle projection has the good visualization. In normal person experiment, For acetabular anterior wall and anterior column, external rotation 20°caudal tilting 30°angle projection shows the good visualization. For acetabular posterior wall and column (including anterior column partially) internal rotation 20°cephalad tilting 30°angle projection shows good visualization. From the pelvic bone model and normal person experiments, the following conclusion are obtained. 1. For posterior wall and posterior column(including anterior column partially), internal rotation 20°, cephalad tilting 30°view is good. 2. For anterior wall and anterior column, external rotation 20°, caudal tilting 30°view is good.

Segmental fractures of the femoral shaft result from high energy trauma such as a traffic accident or falls, and it is frequently accompanied by multiple fractures and severe injuries to other organs. Thus it is very difficult to treat these fractures satisfactorily and several complications can be caused. Early operative intervention and rigid fixation is important to mobilize the patient and to ensure early rehabilitation. Nineteen cases of segmental fractures of the femoral shaft were treated with operative intervention(intramedullary nailing) and followed up between May 1989 and Nov. 1993.; minimal follow-up period was more than one year. Results were obtained as follows: 1. The methods of treatment were interlocking intramedullary nailing in 16 cases(colsed nailing in 7 cases, open nailing in 9 cases) and Kiintscher nailing in 3 cases. Bone grafts were done in 11 cases among 19 cases(8 cases in the interlocking nail group). 2. The closed interlocking intramedullary nailing could be obtained in more shortened operation time than in the open method. 3. There was earlier bone union time in the closed intramedullary nailing than in the open method with bone graft, but there was no statistical significance(SPSS/pc+progam). 4. There was a tendency of earlier bone union time in the proximal fracture site than in the distal fracture site.

46 knees with injured meniscus diagnosed by the use of history and physical examination as well as by arthrography were meniscectomized from January in 1974 to June in 1978. Statistical analysis of data obtained from the histories, physical examinations and arthrographic studies of 46 knees with a mean follow up 6 months after meniscectomy revealed as follows. 1. Lateral meniscus injuries were higher incidence than medial meniscus. 2. In the posterior horn of the medial meniscus and in the middle third of the lateral meniscus on the injured location were more frequently encountered. 3. To compare the results of twe methods of diagnosis were obtained with 67% accuracy by the use of history and physical examination and with 85% accuracy by arthrography 4. We should be able to diagnosis with 91% armed with a history and physical examination and an arthrogram. 5. As being the excellent results after meniscectomy were classified with 78%.

BACKGROUND: Cell-cell adhesion in tissue is mainly regulated by hornotypic interaction of cadherin molecules, which are anchored to the cytoskeleton via cytoplasmic proteins, including a-and / 3-catenin. Loss of E-cadherin and catenin have been attributed a pathogenetic role in tumor invasion. METHODS: We examined the expression of E-cadherin and a-catenin in human thyroid carcinoma by immunohistochemistry. RESULTS: Normal tissue strongly expressed E-cadherin and a-catenin. However, E-cadherin and a-catenin expression were frequently reduced in thyroid carcinoma (E-cadherin: 62.5%, a-catenin: 81.3%). But the expression of E-cadherin and a-catenin in tumors with metastatic spreading were not different with tumors without metastasis. CONCLUSION: These results suggest that reduced E-eadherin and a-catenin expression may be a sensitive marker for disturbance in the adhesive function of the junctional complex, but further evaluation with more cases is needed for confirmation of the result of the same degree of expression in tumors with metastasis.

PURPOSE: To determine the reliability of sonourethrog raphy (SUG) in the evaluation of male anterior urethral strictures. MATERIALS AND METHODS: Both SUG with retrograde saline infusion and retrograde urethrography (RUG) were performed in 5 young normal volunteers and 20 patients with symptoms of impaired urine flow. Those findings were compared with urethroscopic and operative findings in all patients. RESULTS: SUG was more accurate in the evaluation of the stricture length and degree than RUG in 7 patients with anterior urethral strictures, when compared with their subsequent open urethroplasty findings. Only SUG could classify the degree of spongiofibrosis surrounding the strictures in 15 patients. So, SUG was diagnostically as efficacious as or, superior to, RUG in all 20 patients. CONCLUSION: SUG can be used as one of complementary and reliable tools for diagnosis, evaluation and follow-up of anterior urethral strictures.

This study was designed for the evaluation of the mean proportions and range of individual difference of muscle fiber types in human Gastrocneminus, Soleus, Peroneus longus and Tibialis anterior muscles, respectively. Flash-frozen muscle sections obtained from 15 cadavers were stained for H&E, trichrome, PAS, regular & reversed myosin ATPase, succinic dehydrogenase (SDH), acid phosphatase (Ac-Pase) and alkaline phosphatase (Alk-Pase). The results obtained were as follows. 1) Differentiation of muscle fiber types was not evident in H&E and trichrome stained specimen. Three types of muscle fibers were, however, evident in PAS-stained sections according to the degree of positivity in observed skeletal muscles. 2) Two fiber types (Types I and II) were only differentiated and the predominant muscle fiber type was type I by regular myosin ATPase reaction in Gastrocnemius, Soleus, Peroneus longus and Tibialis anterior muscles. 3) Three muscle fiber types (Type I, IIa and IIb) were, however, differentiated and the predominant muscle fiber type was type IIa, contrary to patterns of regular myosin ATPase in skeletal muscles except for Soleus muscle by reversed myosin ATPase stains. Only two muscle fiber types (Type I and II) and predominant type I fibers were shown in Soleus muscle. 4) SDH stains showed three types of muscle fiber except Soleus muscle. The mean proportions(%) of type 1 fibers were 48.0% in Gastrocnemius, 62.3% in Soleus, 40.8% in Peroneus longus, and 39.8% in Tibialis anterior muscles, respectively. 5) The mean proportions (%) of muscle fiber types in human skeletal muscles were markedly different, according to individuals and various enzyme histochemical stains. 6) The size of muscle fibers was relatevely small in type I fibers compared with type IIb. 7) Evaluation for the combination patterns of various enzyme histochemical activities showed that the common muscle fiber types (Type I, IIa and IIb) were markedly reduced in the mean proportions and unusual rare muscle fibers predominant. This predominance of unusual muscle fiber types and marked discrepancy in muscle fiber types between regular and reversed myosin ATPase seemed to be ascribed to decreased muscle enzyme activities following postmortem period.
