An analysis of echocardiograms was made in 50 patients with pericardial effusion of various origins, diagnosed by clinical and M-mode echocardiographic examinations. In these cases the estimated volume of pericardial effusion ranged between 40 ml and 999 ml. The width of echo-free space behind the left ventricular wall which reflect the amount of effusion showed a significant positive correlation with the systolic excursion and the diastolic mean velocity of both right and left ventricular epicardial surfaces. The echocardiographic patterns of so-called pseudo-mitral valve prolapse and a notch on the right ventricular epicardial surface during systole were found more frequently in patients with large pericardial effusion. Thus, in pericardial effusion, and echocardiographic examination is useful for the visualization of the abnormal motions of cardiac structures as well as for its diagnosis.

One hundred fifty-seven patients wha underwent radical hysterectomy and pelvic lymphadenectomy for FIGO stage IB and IIA carcinoma of the cervix between February l975 and May 1987 were retros-pectively analysed to identify specific risk factors associsted with treatment failures. Prognostic factors inciuded clinical stage, histologic cell type, degree of differentiation, size of primary tumor, depth of stromal invasian, lymph-vaseular space invasion, and lymph node metastasis. Treatment results were evaluated according to the recurrence rate and 2-year absolute recurrence-free survival(NED) rate by the prognostie faetors and treatment modalities. Patients with lymph node me tases had a significantly higher incidence of bulky primary(-> 4cm), depth of stromal invasion(> 60% thickness), and lymph-vascular invasion(P<0.005). There was significant difference in the recurrence rate and 2-year, NED rate between cervical carcinoma stage IB and I1A(P <0.005). The pat,ients who had bulky primary tum~or(>4cm) and/or depth of stromal invasion (>60% thickness) had a higher recurrence and lower 2-year NKD rate(P<0.025, P<0.005), Unfortunately, it was not possible to demonstrate that these detrimentel effects could be overeorne by postoperetive radiation. When adjoined for these risk group, traditionally reported poor prognostic factors such as nodal metatasis, cell type and differentiation, lyrnphi-vascular mvasion assume less importance in our studies. In this study, prognosis is most inf1ueneed by clinical stage, depth of stromal invasion, and size of primary tumor,

Pain, traumatic arthritis, joint stiffness and joint subluxation are common sequelae of fracture dislocations of the proximal interphalangeal joints of the finger. Many kinds of methods were used to treat fracture dislocation of the proximal interphalangeal joint. The prognosis is greatly influenced by the method and the time of treatment. Authors treated 4 cases of fracture dislocations of the proximal interphalangeal joint with 3 different method. For a case with small bony fragment, we used the extension block splint of McElfresh. For a old case, we used the volar plate arthroplasty mothod of Eaton. And for two cases with large bony fragment, we used the force couple splint method of Agee after open reduction and internal fixation. The results were satisfactory.

PURPOSE: For the production and evaluation of the tissue-equivalent phantom. MATERIALS AND METHODS: We used agarous gel and oil as a basic component of the mixture and added Tween 80 for the stabilization of phantoms. We did the test for homogeneity and measured T1 and T2 relexation times of each phantom tube. RESULTS: T1 relaxation time ranged from 642 to 2781 msec and T2 relaxation times from 42 to 157 msec. Each phantom was significantly different in T1 relaxation time and T2 relaxation time (p < .0001). CONCLUSION: Tissue equivalent phantom may provide good information on the optimal sequence before MR imaging of patients and may be valuable if it is used with the patients' MR imaging.

The cardiac dimensions and functions were studied by analyzing simultaneously recorded M-mode echocardiograms and phonocardiograms in 24 cases of essential hypertension with no evidence of heart faliure, and also in 20 healthy adults for comparison. Thirteen hypertensives out of 24 had findings consistent with left ventricular hypertrophy on either routine chest roentgenograms or electrocardiograms or both(group II) and the remaining 11 had no such findings(group I). The posterior wall and septal thickness, and isovolumic relaxation time were significantly was increased even in the group I as well as in the group II. The isovolumic relaxation time was correlated well with the septal thickness in both groups. In contrast, a significant increase in left atrial and left ventricular systolic dimensions was noted only in the group II, and so was a significant reduction in the fractional shortening and mean velocity of circumferential fiber shortening. These findings suggest that the echocardiographic examination is useful in patients with essestial hypertension for the early dagnosis of the increased thickness of the posterior wall and the septum, and the abnormality during early diastolic relaxation of the left ventricle, prior to the appearance of the ventricular hypertrophy on the routine chest films amd/or electrocardiograms, and also that echocardiograms enable early detection of the systolic dysfunction of the hypertrophied left ventricle in the absence of apparent failure.

BACKGROUND: Basal cell carcinoma(BCC) is the commonest type of skin malignacy, and its incidence is increasing. As a result, the number of cases requiring treatment by dermatologists may also be increasing. OBJECTIVE: The aim of this study was to clarify the presentation pattern of BCC and to assessce the surgical treatment used in the dermatological surgery clinics in Seoul National University Hospital and Seoul City Boramae Hosptial between 1994 to 1998. METHOD: We reviewed the medical records and checked clinical aspects and surgical treatment methods. RESULTS: The Total number of patients was 33. There were 21 Females and 12 males. The Mean age was 63.1. The most common anatomical site was the face and scalp(30 cases, 91%). The mean size of the tumor was 12.2 by 9.6 mm. BCCs were removed by complete surgical excision with a normal skin margin of 2 to 4 mm. The local flap was most commonly used to repair surgical wounds (55%) and primary closure was used in 39% of patients. A Pedicle flap and full thickness skin graft were also used in surgical defect reconstruction. CONCLUSION: With increasing public awareness and earlier presentation there may be a reduction in tumor size at the time of diagnosis. As most BCCs are found on the head and neck and are usually more or less than 1cm in diameter, it is thought that appropriate education of surgical skills should be needed and offered.

In this study, the feasibility of identification and genotypic differentiation of enteroviruses was investigated by using nested reverse transcription-polymerase chain reaction (nested RT-PCR), single-stranded conformation polymorphism (SSCP), and restriction fragment length polymorphism (RFLP) techniques. Two hundred seventy-four clinical samples were assayed by both nested RT-PCR and tube culture method using MRC-5 and MK cells; 58 (86.6%) out of 67 enterovirus culture-positive samples contained enteroviral RNA. In addition, 114 (55.1%) of 207 samples from patients with suspected enteroviral CNS disease with negative viral cultures were positive by the nested RT-PCR. The nested RT-PCR products were genotyped by the SSCP method and the results were compared with serotypes. We could differentiate 6 subtypes, 3 of which are similar to coxsackievirus B3, B5, echovirus 11, plus 3 other subtypes. RFLP cleaved with Sty I, Bgl I, and Xmn I yielded characteristic patterns for each laboratory strains. This study demonstrates the usefulness of the RT-PCR for the rapid diagnosis of enterovirus infection and the potentials of the SSCP method for differentiation of enterovirus strains.

OBJECTIVE: Immunofluorescence microscopy including confocal laser scanning microscopy and electron microscopy were used to study the production of fibronectin, tenascin, and laminin in the cumulus-corona (CC) cells surrounding mature, unfertilized oocytes after ovulation in view of their presumptive importance in the coordination of the processes leading to fertilization and early embryo cleavage, including the final maturation of the ovum, the sperm-egg interaction, and the complex biochemical mechanism between the ovum and the oviduct. METHODS: Mature oocyte-cumulus complex (OCC) was cultured for 24 and 48 hour and fixed in 3.7% formaldehyde. Specimens were incubated with a mixture of primary monoclonal antibodies recognizing different epitopes of fibronectin, tenascin, and laminin, and then with a mixture of secondary antibodies containing FITC, TRITC, and Cy-5 conjugated antibodies. Observation was made by confocal laser scanning microscope equipped with epifluorescece optics. Transmission electron microscopy were used to observe the OCC at 24 and 48 hours after cultrue. RESULTS: The immunocytochemical date demonstrated that CC masses are capable of producing fibronectin and tenascin but their production is heterogeneous in the CC population. Immunoreactivity to fibronectin and tenascin was shown mostly by inner corona cells, and the intensity of immunofluorescence decreased from the central corona cells to the peripheral cumulus cells. Colocalization of fibronectin and tenascin was evident in most CC cells. Moreover, fibronectin and tenascin immunoreactive material was observed in the intracytoplasmic areas, at the plasma membrane level as well as in the extracellular matrix. Whereas, laminin immunofluorescence was found around plasma membrane and extracellular area, but a intracytoplasmic reaction was rarely observed. The distribution of laminin immunofluorescence was similar to that of fibronectin and tenascin, but in some cumulus cells, colocalization between them was not found. Ultrastructurally, cumulus cells projected numerous long, thin microvilli into the intercellular area and some micovilli penetrated into zona pellucida. The inner layer of the cumulus mass was loose arrangement of relatively uniform, small cells with widened intercellular spaces, whereas in the outer layer, cumulus cells are rather larger in size and compact arrangement by narrow, irregular spaces. A small and large linear gap junctions were easily found at cell contacts. The cytoplasm of most cells had abundant organelles typical of steroidogenesis: numerous mitochondrias, a well-developed smooth endoplasmic reticulum, electron dense lipid droplets, and bundles of microtubules and microfilaments. Rudimentary disrupted basal lamina along the cytoplasmic border was rarely seen in a few inner conora cells. CONCLUSION: Even though the functional role of these extracellular matrix proteins remains still unclear, it is reasonable to suggest that they are necessary in various steps of the reproductive process. Cumulus cells appears to be a heterogeneous and dynamic system for suitable microenviroment of fertilization. And functional differences between corona and cumulus cells during the oocyte denudation may be accounted for particular distribution of these adhesive proteins and steroidogenesis-related organelles.
