I experienced a case of a congenital intramural cyst of the uterine fundus. On examination by light and electron microscope it was composed of a single layer of thin atrophied lining epithelium without secretory activity and was found to be derived from the paramesonephric duct. This case is presented with a brief review of the literature.

The use of a cast-brace in the treatment of tibial fractures was first applied by the authors since 1964 in an attempt to prevent stiffness of the knee resulted from prolonged cast immobilization. The authors attempts on all 43 cases throughout the experimental period were proved satisfactory, among which, however, only a few case showed unwanted result such as delayed union in the early clinical experience.

PURPOSE: The aim of this study was to determine differences in shear bond strength to human dentin using immediate dentin sealing (IDS) technique compared to delayed dentin sealing (DDS). MATERIAL AND METHODS: Forty extracted human molars were divided into 4 groups with 10 teeth each. The control group was light-cured after application of dentin bonding agent (Excite(R) DSC) and cemented with Variolink(R) II resin cement. IDS/SE (immediate dentin sealing, Clearfil(TM) SE Bond) and IDS/SB (immediate dentin sealing, Adapter(TM) Single Bond 2) were light-cured after application of dentin bonding agent (Clearfil(TM) SE Bond and Adapter(TM) Sing Bond 2, respectively), whereas DDS specimens were not treated with any dentin bonding agent. Specimens were cemented with Variolink(R) II resin cement. Dentin bonding agent (Excite(R) DSC) was left unpolymerized until the application of porcelain restoration. Shear strength was measured using a universal testing machine at a speed of 5 mm/min and evaluated of fracture using an optical microscope. RESULTS: The mean shear bond strengths of control group and IDS/SE group were not statistically different from another at 14.86 and 11.18 MPa. Bond strength of IDS/SE group had a significantly higher mean than DDS group (3.14 MPa) (P < .05). There were no significance in the mean shear bond strength between IDS/SB (4.11 MPa) and DDS group. Evaluation of failure patterns indicates that most failures in the control group and IDS/SE groups were mixed, whereas failures in the DDS were interfacial. CONCLUSION: When preparing teeth for indirect ceramic restoration, IDS with Clearfil(TM) SE Bond results in improved shear bond strength compared with DDS.

Oblique single-plane trochanteric osteotomy, in which an oblique cut is made through the femoral trochanteric area and the bony fragments are rotated at the face of the cut in direct contact with each other, allows simulatenous correction of the femoral neck-shaft angle, femoral anteversion as well as flexion/extension effect. Only approximate methods of calculating the correction effects of this procedure have been introduced. Considering unique spatial orientation of femoral neck, we developed a rigorous method to calculate preoperatively the obliquity of the single-plane osteotomy and the amount of rotation required to achieve the target femoral conformation, through geometric analysis. The correction effect by oblique trochanteric osteotomy on the geometry of proximal femur was dependent not only on the amount of change of the neck-shaft angle and femoral anteversion but also on the preoperative neck-shaft angle and femoral anteversion themselves. The flexion/extesion effect was determined by the direction of the correction and the preoperative neck orientation. Computer graphic simulation study confirmed the validity of this method. A program written in QBASIC was introduced to make this complex calculation method more useful in the clinical practice.

Desmoid tumor is a type of fibromatosis usually arise in deep musculo-aponeurotic structures, primarily of the trunk and extremities. It is characterized by proliferation of fibroblastic tissue and does not metastasize but may be locally aggressive. Eventhough the surgical margin reveals clean, recurrence often occurs. To analyze the extent of the tumor and homodynamic characteristics exactly, we performed IV bolus CT. Desmoid tumors show peripheral rim enhancement on early phase scan and more strong, central enhancement on late phase IV bolus CT, which reflects abundant fibroblastic components of the tumor. We report two cases of pathologically confirmed desmoid tumor performed IV bolus CT.

BACKGROUND: Arterial blood gas analysis are highly susceptible to preanalytic error due to improper method of obtaining or handling the blood sample before analysis. The error in measurement of blood gas analysis are loss of CO2 by exposure to atmospheric air, effect of anticoagulant itself, temperature difference between the experimental subject and the measuring electrode and metabolic change which occur between blood sampling and measurement. METHOD: To study the effect of the delay in estimation of blood gas and drawn blood on values of blood gas partial pressure and pH. Blood sample were divided into 2 groups according to the method of storage, group I stored at 24~25degrees C(room temperature) under anaerobic condition. ;group II stored at 0~4degrees C(refrigerator) under anaerobic condition. The samples were analyzed by time interval through 180 minutes in each group. RESULTS: The result were as follows: 1) PaO2 decreased significantly after 10 mins in group I, whereas it decreased significantly after 20 mins in group II. 2) PaO2 increased significantly after 20 mins in group I, whereas it increased significantly after 120 mins in group II. 3) pH decreased significantly after 60 mins in group I, whereas it decreased significantly after 120 mins in group II. 4) No significant changes of bicarbonate and SaO2 were noted in each group CONCLUSION: From above results, it would be advisable to analyze the sample in a short period of time or to store in a refrigerator when the measuring will be delayed. So we highly recommend that blood gas analysis should be performed as soon as possible after sampling, especially within 10 minutes.

M. supracostalis anterior is a rare varlation which occurs on the external aspect of the upper thoracic wall. This thin, short-like musc1e lies deep to the pectoralis major and minor muscles, and extends longitudinally over the upper four or five ribs. It is known that the muscle usually occurs bilaterally but sometimes unilaterally. In the present report, a case of unilateral (right) M.supracostalis anterior, observed in a 58-year-old man cadaver, is described. Because the muscle had not been reported in Korea, morphological characteristics and nerve innervation of the muscle were investigated. 1. M. supracostalis anterior, observed only on the right side, extended longitudinally from the first rib to the fourth rib deep to the pectoralis minor. 2. The suprarostalis anterior arose from the antero-inferior surface below the groove for subclavian vein of the first rib. After arising from the first rib, the smaller, more media part of the muscle inserted into the upper border of the fourth rib and the larger, more lateral part inserted into the upper border of the fourth rib. 3. The length of the musce is 9.9cm, and the width is 0.8cm at its origin, 1.7cm at the upper border of the third rib and 2.4cm at the upper border of the fourth rib. 4. It was confirmed, under stereomicroscope, that the muscle was innervated by the terminal branches of the nerve to the first external intercostal muscle deriving from Thl and Th2. Blood supply of the M. supracostalis anterior was provided mainly by the lateral thoracic artery arising from the axillary artery.

To evaluate the relationship between arteriolosclerosis and diabetic retinopathy, we graded the levels of diabetic retinopathy and arteriolosclerosis and compared each other in 255 patients with non-insulin dependent diabetes. And we also measured serum lipid levels and checked other risk fac-tors for diabetic retinopathy. SPSS was used for statistical analysis. Patients with advanced arteriolosclerosis were at higher risk of severe diabetic retinopathy. And patients with elevated plasma total cholesterol, LDL-C, TG had more severe levels of diabetic retinopathy than whose lipid levels were normal. These results suggested that advanced arteriolosclerosis and elevated serum lipid levels are associated with severe diabetic retinopathy. For preventing visual threatening complications of diabetic retinopathy, the degree of arteriolosclerosis and serum lipid levels should be carefully monitored in the evaluation of diabetic retinopathy.
