Ultrasongraphy is a safe, noninvasive examination which should be the first procedure in the workup of apatient with a definite or suspected pelvic masses. The diagnostic schemes were derived from correlating the sonographic features with histomorphology in 230 surgically proven pelvic masses. Besides separating pelvic masses into the conventional categories of cystic, complex and solid, grayscale sonographic features of a pelvic mass canbe used to subcategorized these masses into a more useful differential diagnosis. The results are as follows; 1.The most characteristic finding of uterine myoma was midly to mederately echogenic uterine enlargement (90.7%)with a lobulated uterine margin (62.8%), and often less echogenic than the normal uterine echoes. 2. The typical ultrasonographic finding of H-mole was uterine enlargement with multiple small vesicular patterns of intrauterincontents(93%). 3. The most frequent finding of cystic teratoma was cystic mass with echogenic foci(48%), but the echogenic appearance of the lesions was extremely variable. 4. The ultrasonographic findings of ectopic pregnancywere adnexal mass(comlex or cystic), decidual proliferation of the uterus, enlargement of uterine size, fluid incul-de-sac, deveiation of uterus by adnexal mass, and psuedointrauterine appearance. 5. Ultrasound provided information leading to the correct diagnosis in 57% of cases, contributory data in 21.3%, and non-specific information in 10.4%. Errors occured in 3.9% and false-negative in 7.4%.

Segmentalization of spinal fixation enhances correction of the coronal plane deformity and allows preservation of normal sagittal contour offering rigid fixation. Purpose of this paper was to evaluate the efficacy and safety of segmental pedicle screw fixation in the treatment of idiopathic thoracic scoliosis. From 1987 to 1991, 78 idiopathic thoracic scoliosis patients were treated with CD instrumentation. Thirty-one were treated with hooks, 23 with pedicle screws inserted in hook pattern and 24 with segmental pedicle screws. In segmental screw group, the screws were inserted for every other on the convex side. After follow up of minimum 2 years(range:24 to 52 months), the results of coronal, sagittal and rotational correction were compared. Major curve correction was 55% with hooks, 66% with hook pattern screws and 72% with segmental screws, with loss of correction of 6%, 2% and 1% respectively. Compensatory curve correction was 57% with hooks, 67% with hook pattern screws and 70% with segmental screws. In patients with hypokyphosis, all groups showed significant improvement, with best restoration in segmental screws. Rotational correction of the apical vertebra was 19% with hooks, 26% with hook pattern screws and 59% with segmental screws. Thirteen(3%) screws were malpositioned but they did not cause neurologic impairment nor adversely affect the results of treatment. This study implies that the segmental pedicle screw fixation is safe and effective method of correcting the triplanar deformity of the thoracic idiopathic scoliolis.

Recent immunological investigations have demonstrated that the patients with psoriasis have various humoral and cellular immune abnormalities, such as increased serum IgG, IgE and secretory IgA, anti-IgC factor in psoriatic lesions, in peripheral blood lymphocytes and in serum, rhumatoid-like factors in IgA and IgG classes of immunoglobulins, antinuclear antibodies (ANA; reacting with the basal cell nuclei of uninvolved skin., anti-stratum corneum antibody and complements in psoriatic scales, immuoglobulin and complement bearing polymorphonuclear leucocytes in the Muro microabscess. These abnormal findings are enough to suggest an autoimmune mechanism in the pathogenesis of psoriasis. Several investigators have also reported the results of T cell enumeration in the peripheral blood in psoriatic patients. However, the results are not in general agreement,. Thee present study was undertaken to clarify any abnormality in the proportion of T cells in the peripheral blood in psoriatic patients. Forty-one patients with active psoriasis registered at the Department of Dermatology, Seoul National University Hospital entered this study from May, 1979 through April, 1980. Twelve healthy medical and paramedical personel the comprised the control group. Active and total T cells were enumerated by the method of E-rosetting technique, and the results were as follows. 1, in normal controls, the active and total T celIs identified as E rosetteforming cells accounted for 61.6+7.4% and 68.1+8.9% of the total lymphocyte population, respectively. 2. In patients with psoriasis, significant decrease of active T cells (54. 2,+11.0%,p<0.005) and total T cells (62.2+11.2%, p<0.05) was observed. More profound reduction of T cells was noted in patients with wide spread psoriasis than those with limited extent.

BACKGROUND: Tumor angiogenesis is required for tumor growth and metastasis. In this study, we investigated the correlation between the intensity of angiogenesis and stage, nodal status, histologic type, metastasis and survival rate of non-small cell lung cancer. METHOD: Formalin fixed, paraffin embedded surgical specimens of 45 patients who had surgically resected primary non-small cell lung cancers without pre or post perative adjuvant chemotherapy or radiotherapy were examined. The microvessel count(MVC) was demonstrated by immunohistochemical staining for CD31(platelet ednothlial cell adhesion molecule, PECAM). RESULTS: Microvessel counts(MVCs)in stage IIIA and IIIB were higher than in stage I and II(p<0.05). The MVC in patients with lymph node metastasis was higher than that in patients without lymph node metastasis, although the difference was not statistically significant(p>0.05). However, in adenocarcinoma, the MVC in patients with lymph node metastasis was significantly higher than that seen in patients without lymph node metastasis(p<0.05). The MVC in adenocaricinoma was higher than that in squamous cell carcinoma(p<0.05). The difference between the MVCs of adenocarcinoma and squamous cell carcinoma was not statistically significant in stage Iand II or NO stage(p>0.05). However, in stage IIIA and IIIB or N1~3 stage, the MVC in adenocarcinoma was higher than that in squamous cell carcinoma(p<0.05). MVC was more increased when metastasis developed within 12 months. In the same histologic type and stage, the duration of survival time in patients with high MVC was shorter than in patients with low MVC, however the difference was not statistically significant(p>0.05). The survival rate in patients with high MVCs was lower than that in patients with low MVCs(P<0.05). CONCLUSION: In non-small cell lung cancer, MVC correlated relatively well with pathologic stage, nodal status (limited in patients with adenocarcinoma), histologic type, postoperative metastasis and survival rate. However, in the same histologic type and stage, MVC was not significantly related to the duration of survival. Therefore the assessment of the intensity of angiogenesis in non-small cell lung cancer may be helpful in predicting prognosis and in selecting patients for systemic adjuvant therapy of potential metastasis according to the results.

Ribavirin(l-b-D-ribofuranosyl-l, 2, 4-triazole-3-carboximide, Virazole) is a. synthetic nucleoside derivative with reported broad spectrum activity in vitro and in vivo against a wide variety of DNA and RNA viruses. This drug works by selective inhibition of viral protein in the early stage of viral replication, but does not influence on host cell protein. The present study was undertaken to evaluate the therapeutic effect of Ribavirin in patients with herpes zoster. A total of 15 patients entered this study at the Department of Dermatology, Seoul National University Hospital during 5 months' period, from May, 1980 to September, 1980, Ribavirin(10mg/kg/d) was given to 10 patients. After initiation of therapy, we observed duration of pain and vesicles and onset of crust formation in each patient clinically. The results observed in the 15 patients were as follows. 1. The average duration of pain was 6.0 days in Ribavirin group and 8.6 days in. control group (p<0. 05). 2. Postherpetic neuralgia was not found in any patients treated with Ribavirin. 3. The average duzation of all vesicles and onset of crust formation were 7.0 days and 3.8 days in Ribavirin group and 7.2 days and 4.2 days in control group respectively. 4. No side effects were observed during the course of Ribavirin treatment.
