Effect of succinyleholine on the intra-ocular pressure was assessed in 29 surgical patients. After pretreatment of thiopental in a dose to induce the loss of eye-lid reflex the intra- ocular pressure was measured following intravenous administrdtion of succinylcholine. The following were the results. 1) Thiopental showed a significant lowering effect on the intra-ocular pressure. 2) A small dose(0.5mg/kg) of succinylcholine, given immediately after thiopental restored the intra-ocular pressure to the preanesthetic level. 3) A large dose(1.0~2.0mg/kg) of succinylcholine, administered immediately after thiopental, sustained the intra-ocular pressure below the preanesthetic leve. 4) Teacheal intubation caused a rise of the intra-ocular pressure above the preanesthetic level, more significantly than that of succinyleholine. 5) Suecinylcholine, in a large dose, showed a depressing effect on elevation of the intraocular pressure induced by tracheal intubation.

1) Atropine and scopolamine in doses of 0. 05, 0. 1, 0, 15, 0. 2 and 0. 25 mg produced bradycardia in humans. 2) The bradycardia induced by 0. 05 and 0, 1 mg of atropine was restored to normal rhythm by 0. 2 and 0. 15 mg of atropine, respectively. 3) The bradycardia induced by 0. 05 and 0. 1 mg of scopolamine was reversed to tachycardia by 0. 2 and 0. 15 mg of scopolamine, respectively. 4) The scopolamine(0.05mg) induced bradycardia was restored to normal rhythm by atropine 0.15 mg and reversed to tachycardia by atropine 0.2mg 5) The atropine(0.1 mg) induced bradycardia was partially restored by scopolamine 0.15 and 0. 2 mg. 6) It was argued that these results were not explainable by a central vagal effect of a direct effect of atropine and scopolamine on the heart but explainable by the blocking effect of these drugs to the sympathetic ganglia.

Acute epiglottitis is an inflammatory process of supraglottic region, which involving the epiglottis andhypopharynx region. This disease can be recognized easily radiologically and virtually all death are preventable.The lateral neck radiograph with soft tissuse technique is of critical value when the diagnosis is in doubt andusually characteristic when compared to the normal. Authors reviewed available lateral neck radiograph of 92 casesamong the 95 cases of clinically confirmed adult epiglottitis during 4 years in wallace Memorial Hospital. Theresults are as follows; 1. Male to female sex ratio was 13:2. 2. The most common age group was 4th decade. 3. Themost common clinical symptoms are sore-throat (87%) and dysphagia(87%). 4. The radiologic findings are swelling ofhypopharynx(92%), vallecular narrowing or obliteration (92%), uvula swelling (33%), narrowing of airway adjacentto epiglottis (17%), swelling of prevertebral soft tissue(8%).

Although ultrasound has not been used to clarify bone lesions because of their high acoustic impendence and attenuation coefficient, aneurysmal bone cyst of the pelvis was imaged with ultrasound. Dual fluid levels and multiple loculations were discovered by ultrasound imaging through thin cortical bone. Ultrasonography is a simple, non-invasive method which can be utilized to detect bony lesions of an expansile nature and reveal characteric findings in an aneurysmal bone cyst.

The reliability of emergency ultrasonographic(US) detection of hemoperitoneum and solid organ injury in blunt abdominal trauma was evaluated retrospectively. From October 1,1995 to August 31,1996,90 patients were included in the study. Ultra- sonographic findings showed a sensitivity, specificity, and accuracy of 97.6%, 97.9%, and 98.1%, respectively, in detecting intraabdominal fluid collection. We believe that US in an emergency center is a quick, safe screening method in the evaluation of blunt abdominal trauma. In our department, US has replaced diagnostic peritonaeal lavage(DPL) and computed tomography(CT) as the screening study of first choice.

Chondroblastoma is a rare primary neoplasm of bone which involves the epiphysis of the long bone and develops mostly in the 2nd decade of life. We reviewed the cases of twenty patients with chondroblastoma who were treated at the Department of Orthopaedic Surgery, Yonsei University College of Medicine between 1969 and 1989. All patients were followed for 1 year or longer. The results were as follows. 1. The proximal end of the humerus(25%) and the proximal end of the femur(25%) were the most common sites. 2. 85% of patients were between 11 to 20 years old and male to female ratio was 3:2. 3. The most common symptom was pain and in 30% of patients it was appeared after minor trauma. 4. The average diameter of lesion is 4.2cm in its long axis and the more longer the duration, the more larger the size of lesion. 5. Involvement of the epiphyseal plate was twice as common in the patients with a closing plate as in those with an open one. 6. The most common microscopic finding was the presence of chondroblast and chondroid matrix. 7. Two patients(10%) had a local recurrence. 8. The final functional results were considered to be good in sixteen(80%) patients. 9. Accurste localization of the lesion during biopsy is very important especially in the case of deep seated lesion.

Osteoclasts resorb bone by the hydrogen ions and proteolytic enzymes in the localize environment under the ruffled border. Before releasing hydrogen ion and enzymes, osteoclast should attach to bone surface very tightly and make a room to release enzymes and hydrogen ion in the center. Specialized attachment molecule in the cell membrane, such as integrin, is associated with specific noncollagenous protein in the matrix, which has specific amino acid sequence (Arginine-Glycine- Aspartic acid sequence). We may speculate that osteoclast action would be decreased if the integrin is blocked by antibody or RGD protein. In this study, the osteoclasts were cultured on the coverslip or bone slice with or without RGD protein in the culture medium, and numbers of growing giant cells were much less in group with RGD protein. The number resorption pits, formed on mineralized bone slice, was also lower in the group adding RGD protein in the medium. And we made a conclusion that the osteoclastic bone resorption was inhibited by soluble RGD protein.

We report a case of acute septic arthritis of the hip in a child due to H. influenzae with review of the problems encountered. A one year and 9 months-old male child was admitted because of fever, limping and restlessness of 48-hour duration. Under the impression of septic arthritis of the right hip, blind broad-spectrum antibiotic regimen was initially instituted. Fever subsided immediately and two blood cultures yielded no growth, as did joint tapping. But fever recurred on the 8th day of admission. MRI demonstrated fluid collection in the right hip. Arthrotomy yielded thin pus. The antibiotic regimen was shifted to vancomycin, according to the culture report of S. aureus. However, spiking fever continued. On the 4th week of admission, recheck MRI demonstrated fluid collection in and out of the hip joint. A second arthrotomy yielded frank pus. H. influenzae was reported in pus culture for the first time, being susceptive only to chloramphenicol. Fever was down to normal temperature after injection of urfamycin. Radiograph on the 17th day after the 2nd arthrotomy revealed posterior dislocation of the right hip. MRI demonstrated granulation tissue within the acetabulum. Open reduction confirmed granulation tissue without pus. This case suggests: 1. Routine blind antibiotic regimen for gram-positive and negative organisms in the initial phase of treatment may fail in the rare case of H. influenzae. This may lead the surgeon to miss the optimum time of surgical intervention despite early diagnosis, 2. Arthrotomy may fail if not followed by antibiotics sensitive to the pathogen. 3. Delayed pathologic dislocation may ensue due to invasion of granulation tissue.
