With the increasing number of the occupational accidents proportionate to the rapid development of modern culture, fractures of the hand have become one of the commonest fractures of the human body. The authors have reviewed 211 cases of injured hand in industry which were treated in the department of orthopedic surgery, InCheon Severance hospital from Jan. to Dec. in 1989. The following results were obtained; 1. The peak incidence was in the age group from 21 to 30 years in 87 cases (41.2%). Injured males outnumbered females predominantly by 92.9% vs 7.1%. 2. The hand injuries happened most commonly in the day time (from 8 oclock A.M. to 6 oclock P.M.) but there were no differences between month in the year. 3. Most of patients injured hand (73.9%) arrived at hospital within 1 hour after accidents. 4. The commonest cause of the injury was due to electric saw (21.9% ). 5. Of the 98 fracture cases left hand was more frequently involved than right hand and 64 cases monodigit and remained were polydigits. 6. 43 (32.6%) of total 132 fractured sites were index finger and 74 (56.1%) were distal phalanx. 7. The index finger was also most vulnerable to amputation (56.8% out of 44 amputation cases) and the most distal part was more vulnerable to amputation. 8. The most common method was primary closure and splint. The method of treatment was affected in part by the economic and social status of the patients. 9. In order to prevent hand injuries in industry, preventive policy should be established by improvement of working environments, machines and education.

Higenamine was isolated originally from Aconiti tuber from Aconitum species and recently Higenamine was synthesized. The purpose of this study is to investigate the adrenergic effect of Higenamine on rabbit cardiovascular system. Blood pressure, cardic output, systemic vascular resistance and heart rate were measured after intravenous injection of Higenamine(2-100microg/kg/min). The effects of Higenamine were compared with those of other sympathomimetic drugs. The changes in the cardiovascular systems after pretreatment with Propranolol, Atenolol and Hexamethonium were also studied. The following results were obtained. 1) Higenamine increased the cardic output and the heart rate and decreased the blood pressure and the systemic vascular resistance. Those changes were dose-dependent. The duration of action of Higenamine was 5 to 8 minutes. 2) The effects of Higenamine were similar to those of Isoproterenol. The amount of Higenamine was more than 100 times the required amount of Isoproterenol in order to obtain the same casdiovascular effects. 3) The effects of Higenamine were blocked by Propranolol, The increase of cardic output and heart rate were blocked by Hexamethonium. Higenamine has stimulating action on beta1 and beta2 receptors. But Higenamine is much less potent than Isoproterenol.

Cutaneous angiosarcorriias occur most commonly on the face and scalp of elderly individuals and are characterized by poor prognosis. We present a case of angiosarcoma in a 17-year-old boy not associated with any predisposing factors. The patient had three, ill-defined, 3 to 5 cm sized, erythematous, indurated subcutaneous nodules on the right upper extremity with a duration of 3 months. On histological examination, there were extravasated erythrocytes and irregular vascular channels lined by atypical endothelial cells in the dermis and subcutaneous tissue. The tumor cells appeared to dissect the collagen bundles. The patient was treated by wide surgical excision and post operative radiation therapy. However, 16 months after the operation, local recurrence was found to involve the close areas to the excision site on the right upper extremity and right axillary lymph nodes.

Osteoid osteoma is a small, oval or roundish, nidus like neoplasm of bone. The lesion usually does not exceed a centimenter in its greatest dimension, and it consists of osteoid, trabeculae of newly formed osseous tissues and a substratum of highly vascularized osteogenic connective tissue. In a differential diagnosis, consideration should be given to Brodies abscess, sclerosing osteomyelitis of Garre, Fibrous dysplasia and healing fractures. From Janua 1960 to December 1980, we have seen and studied 18 cases of osteoid osteoma and the results obtained from this study were follows: l. Eleven cases were found in second decade and 17 cases were developed before thirty years old. 2. The sex ratio was nearly equal and duration of disease from onset was average 16 months. 3. Location of lesions were predominantly in lower extremities, 9 in tibia and 3 in femur. 4. Pain was noted in 16 cases and aspirin affected in 8 cases. 5. Nidus was found in 11 cases. 6. All cases were treated by radical excision of lesions with disappearance of pain and satisfactory results.

PURPOSE: To evaluate the specif!c radiologic findings of the dysgenesis of corpus callosum(CCD) on CT and/or MR images. MATERIALS AND METHODS: The authors reviewed retrospectively CT and/or MR images of 10 patients with CCD. After classifying CCD into partial and total type according to the degree of its development, we investigated structural abnormalities on CT and/or MR images resulting from or related to CCD and then associated anomaly. RESULTS: The most common findings of CCD on axial planes of CT and/or MR images were dilatation of posterior part of the lateral ventricles(8/10) and feature of the bodies of the both lateral ventricles(8/10) in parallel. Sagittal and coronal planes of MR demonstrated exact extent of dysgenesis of the corpus callosum(5/5) and radiating pattern of gyri in medial surface of cerebral hemisphere extending to the 3rd ventricle without interruption by cingulate sulcus(4/5). CONCLUSION:MR image of mid-sagittal plane appeared most useful in diagnosis of CCD because of its direct depiction of the whole length of corpus callosum. In most cases, however, CCD can be easily diagnosed with CT scan by characteristic findings of dilatation of the posterior part of lateral ventricles and paralleling of the lateral ventricles.

The diagnostic possibility and the incidence of ectopic pregnancy are increasing due to several factor. Furthermore, radioimmunoassay of serum β-HCG and US make it possible to diagnose early before the tubal rupture. A conventional surgical approach has been considered as a choice of treatments. Until recent years, however, surgery may have considerable risk of infertility and sugical hazard. In view of the natural tendency of some ectopic pregnancies to terminate in tubal abortion or complete resorption, we tried to cure ectopic pregnancy with nonsurgical transcervical intervention. Five of 8 patients with unruptured tubal pregnancies, it was possible to inject PGF2a into the tubes or gestational sac. 4 of them were ended up with satisfactory reduction of serum β-HCG level and improvement of symptoms & signs. In only one patient, β-HCG level remained a high level continuously, so salpingectomy was done. As a result, we consider that fluoroscopy-guided transcervical interventional procedure is a useful treatment modality for early unruptured ectopic pregnancy.
