Gastric volvulus is a rare surgical disorder in the pediatric population. We experienced a case of gastric volvulus. A 2-year-old boy was admitted to hospital with abdominal distension. An upper gastrointestinal series showed reversal of the greater and lesser curvatures. Surgical exploration revealed an organoaxial volvulus of the stomach, and anterior gastropexy was performed.

A retrospective clinical observation was done in 90 cases of acute myocadial infarction admitted to Hanyang University Hospital from July 1972 to Dec. 1980. The following results were obtained. 1) The ratio of male to female was 2.3:1. Most patients(63.2%) were in the age groups between the 6th and 7th decades. 2) The main symptoms of acute myocardial infarction were chest pain(76.6%), dyspnea (64.4%), radiating pain(27.7%), epigastric pain(18.8%) and palpitation(15.5%). The painless infarction accounted for 11.1% of all cases. 3) The most common preceding disease was hypertension(38.5%) and other associated diseases were diabetes mellitus(13.2%), C.V.A.(8.8%), angina pectoris(8.8%), previous myocardial infarction(6.6%) and drug intoxication(3.3%). No preceding diseases were found in 12.0% of cases. 4) The anterior wall infarction was 45.5% of 90 cases, inferior wall infarction 22.2%, antero-inferior wall infarction 11.2%, subendocardial infarction 7.7%, posterolateral infarction 2% on ECG. 5) The mortality rate of patients according to the Killip class was 4.2% in class I, 14.3% in class II, 50% in class III and 76.9% in class IV. Group of high Killip class was associated with high mortality. 6) In long term prognosis according to Norris' coronary prognostic index, the highest value was 11.72 with average value of 7.02+/-2.65 in survival group, whereas in death group, the lowest value was 5.08, the highest 16.88 and average value was 10.4+/-3.86. 7) High risk subgroup who complicated within the first 4 admission days, occupied 21.1% and low risk subgroup without complication occupied 46.7%. After the 5th admission days, 2.2% of high risk subgroup was expired, whereas there was no death cases in low risk subgroup. 8) Average duration of hospitalization was 22.4+/-9.5 days in high risk subgroup and 17.3+/-6.8 days in low risk subgroup. In low risk subgroup, 10 cases were discharged within the 7th day of admission and 30 cases after the 8th day of admission. 9) 89.5% of total death occured within the 4th hospitalized day, and 66.7% of cases under systolic BP of 84mmHg were expired. Definite cardiomegaly on chest X-ray and past history of myocardial infarction were associated with high mortality. Half of cases with pulmonary edema were died.

Met protein is a transmembrane 190 kD heterodimer with tyrosine kinase activity, encoded by c-Met oncogene. It serves as a high affinity receptor for hepatocyte growth factor (HGF)/scatter factor (SF), a cytokine which stimulates cell proliferation, motility, and invasion. In this study, we immunohistochemically evaluated the expression of Met/hepatocyte growth factor receptor in colorectal cancers. Met protein was expressed in 31 of 72 patients (43.1%). The staining pattern was cytoplasmic in nature, present throughout the tumor, and showed variable intensity from case to case. The relationship between the expression rate and intensity, and age and sex of patients, tumor size (p=0.645), tumor site (p=0.902) and tumor differentiation (p=0.844) was not statistically significant. The expression rate and intensity were significantly correlated with lymphovascular invasion (p=0.001), lymph node metastasis (p=0.010), depth of invasion (0.019), and stage (p=0.023). Cytoplasmic accumulation of Met protein was not associated with enhanced PCNA index of tumor cells (p=0.052). These results suggest that Met protein may play an important role in the invasion and metastasis of colorectal cancer cells.

For the purpose of evaluating the effect of both direct retainer design and bony absorption degree around abutment of indirect retainer on the supporting tissue of abutment of indirect retainer, dislodging force was transmitted to unilateral distal extension RPD bases. Analysis of stress distributed within the supporting tissue around abutment of indirect retainer was carried out. Using three-dimensional photoelastic stress analysis method and the conclusion is a follows. 1. According to the extent of force which the direct retainer of the most distal abutment tooth, the amount of force transmitted to the abutment tooth of indirect retainer was small. 2. Of all the cases, Mandibular first premolar which was used abutment tooth of indirect retainer, buccal, mesial and distal sides represented compression stress and lingual side represented tensile stress. 3. The more bone resorption of abutment tooth of indirect retainer, the more distortion of buccal and distal side of abutment tooth was existed and the extent of compression stress which was existed and distal side to abutment tooth was large. 4. When the alveolar bone around the abutment with indircet retainer is normal. The amount of force transmitted on abutment with indirect retainer was small in the order of Akers clasp, RPA clasp, RPI clasp. 5. When the alveolar bone around the abutment with indirect retainer has been absorbed 20% and 30%, the amount of force transmitted on abutment with indirect retainer was small in the order of RPA calsp, RPI clasp, Akers clasp. 6. When denture is displaced, shape of the direct retainer reciprocating abutment affect much the function of indirect retainer.
