BACKGROUND: Electroconvulsive therapy (ECT) that works by electrically inducing grand mal seizure is an effective therapy for patients with major psychosis and affective disorders. But ECT may produce intense stimulation of the central nervous system resulting in hypertension and tachycardia. Such an acute hyperdynamic state may be undesirable because of possible cardiovascular complications. We compared the ability of different bolus doses of esmolol to blunt the hemodynamic effects of ECT. METHODS: Twenty ASA physical status 1~2 patients were enrolled in a crossover design study to determine the effects of two standard esmolol bolus doses (0.5 mg/kg and 1.0 mg/kg) on the hemodynamic response and seizure duration during ECT. In each patients receiving esmolol or placebo, arterial pressure, heart rate, seizure duration and peripheral oxygen saturation (SpO2) were recorded. RESULTS: The seizure duration with placebo was 43 +/- 9 sec, esmolol 0.5 mg/kg bolus dose was 39 +/- 14 sec and esmolol 1.0 mg/kg bolus dose was 39 +/- 12 sec, but it was not significant. Compared with esmolol 0.5 mg/kg bolus dose, esmolol 1.0 mg/kg bolus dose decreased blood pressure and heart rate during ECT more effectively. CONCLUSIONS: Esmolol 1.0 mg/kg bolus dose was considered to be the better dose in blunting the hyperdynamic response during ECT without shortening of seizure duration.

It is well known that there is close relation of the left atrial pathology to atrial fibrillation(AF) in patients with mitral valvular disease. To evaluate such relation is existed or not in the right atrium, the right atrial wall biopsy was performed in 31 patients with mitral valvular disease during valve surgery. The specimens obtained were interpretated by the pathologist who had no information about the patients. The specimens were graded according to severity of morphological change. In Grade I, the atrial myocardium is degenerated and has moderate fibrosis in it. Grade II shows the atrial myocardial layer of the atrium and severe degenerated with pre and postoperative heart rhythm. Four patients had Grade I change and 3 patients among them had pre and postoperative AF. Eleven patients had Grade III changes and 9 among them had pre and postoperative AF. The results show there is strong tendency that the patients with pre and postopeative AF had Grade III change in the right atrium and the relation of the right atrial pathology to AF is same as that of the left atrium.

A total of the 16 cases of rheumatic vavular heart desease were examined in order to compare fibrillatriy F wave with left atrial size and biopsy findings from October 1986 to April 1987 at the Ewha Womans University Hospital. The results were as follows : 1) Of the 16 patients, there were 5 males and 11 females. The mean age of the patients was 41.9+/-12.7 years old. 2) Among the 16 patients PTF-V1 was lesser than -0.04nn-sec, the left atrial size measured by M-mode echocardiography was 57.1+/-8.9mm. Inverse correlation between PTF-V1 and the left atrial size measured by M-mode echocardiography was observed(P<0.01). 3) No significant correlation between PTF-V1 and left atrial was found(P>0.01). 4) There was a tendency that the size of the left atrium was, the more degeneration, necrosis and fibrosis of the left atrial wall appeared through pathological findings.

In order to evaluate the effecacy of 2D-Doppler echocardiography for the measurement of pulmonary flow(Qp), systolic flow(Qs), the ratio of pulmonary flow and systemic flow and systemic flow(Qp/Qs), 19 membranous ventricular septal defect patients were examined in the period from July, 1986 to October, 1987 at Ewha Women's university hospital. The measurement of Qp, Qs, Qp/Qs by 2D-Doppler echocardiography were compared with the results by the Fick's method of cardiac catheterization.The following results were obtained. 1) The total of the 19 patients consisted of 15 males and 4 females. The mean age of the patients was 8.2 years. 2) It was found that the Fick's method and 2D-Doppler measurements of Qp (n=19, r=0.67), Qs (n=19, r=0.88), and Qp/Qs ratio(n=19, r=0.62) were highly correlated(p<0.01). 3) It is understood that the measurement of Qp, Qs, Qp/Qs ratio by 2D-Doppler echocardiography were quite useful to the noninvative diagnosis of ventricular septal defect.

OBJECTIVES: The myelodysplastic syndromes (MDS) are a group of acquired clonal hematopoietic disorders characterized by peripheral cytopenias and a hypercellular or normocellular dysplastic bone marrow. The mechanisms responsible for development of MDS are not known. We performed this study to evaluate the hematopoietic abnormalities and apoptosis in MDS. METHODS: Long-term bone marrow culture (LTBMC) was performed for colony assays, cobblestone area assay, stromal morphologic changes from 7 patients with MDS and 7 normal controls. In situ nick end labeling (ISNEL) method was performed for detection of apoptosis from LTBMC in 7 patients with MDS and 7 normal controls. ISNEL method also performed in bone marrow cell bloc samples in 36 patients with MI3S. RESULTS: Viability of nonadherent cells from LTBMC of patients with MDS was not decreased compared with normal controls at 1 week, but significantly decreased at 2 and 3 weeks compared with normal controls (P<0.0001). Formation of the cobblestone areas from patients with MDS was slightly decreased compared with normal controls at 1st week, but significantly decreased at 2nd and 3rd weeks compared with normal controls (P<0.0001). Slightly decreased compared with normal controls at 1 week, but significantly decreased at 2 and 3 weeks compared with normal controls (P<0.0001). Stromal layers produced in LTBMC of normal controls and 1 patient with MDS were detected at 1 week and were formed confluent stroma from 3 weeks, but another patients with MDS who did not form a confluent stroma. Patients with MDS had significantly lower colony forming unit granulocyte-macrophage (CFU-GM) compared with normal controls at 1 (P<0.01) and 2 weeks (P<0.001) of LTBMC. Two weeks of LTBMC resulted more profound inhibition of CFU-GM formation than 1 week (P<0.0001). Apoptotic cell death was absent in adherent and non adherent cells from normal controls at 1 and 2 weeks, but massive apoptotic cell death was found in adherent and non adherent cells from patients with MDS at 1 and 2 weeks and the degree of apoptosis was profound at 2 weeks compared with 1 week. Among the 36 patients, fifteen patients demonstrated varying degrees of apoptosis positive cells, 4 having low, 8 intermediates, and 3 high scores. Remaining 21 patients showed absent apoptosis or only occasional positive cells. CONCLUSION: Hematopoietic abnormalities such as a failure of differentiation are caused by the stromal defects and the biologic basis of the apparent paradox of peripheral cytopenias in the face of hypercellular (or normocellular) marrow is related by intramedullary apoptotic cell death of the stromal and hematopoietic cells.

A malformation of azygos and hemiazygos system were observed from the cadaver for anatomy practice in College of Medicine, Chungnam National University. The observing results were as followings ; Hemiazygos vein was connected with left superior vena cava and drained into coronary sinus, which engorged enough to fill up with blood about 20cc to 30cc. Communicating pathway from hemiazygos vein to azygos veln wasn't found the diameter of left brachiocephalic vein was very small, about 2mm to 3mm. And, the diameter of left internal jugular vein was smaller than that of right infernal jugular vein. In this case, the azygos and hemiazygos system ceased its development at early embryologic stage(around 7 week embryo) and didn't progress into next stage.

Wegener's granulomatosis (WG) is an antineutrophil cytoplasm antibody (ANCA)-associated small-vessel vasculitis characterized by ear, nose, and throat (ENT) involvement, pulmonary disease, and glomerulonephritis, less commonly, the eyes, joints, skin, neurologic and cardiac tissue. Cutaneous manifestation as an initial presentation is unusual and about 15% of patients with WG will developspecific skin lesions at some time during the course of the disease. The most common skin lesion specific to WG is palpable purpura with the histopathologic correlate of leukocytoclastic vasculitis. However, a wide array of clinical and histologic features may be seen. Glomerulonephritis eventually develops in about 80% of patients, although only 20% have renal disease when they first present. Clues are proteinuria and active urine sediment containing dysmorphic red blood cells and red blood cell casts. We report a patient with Wegener's granulomatosis who presents as hematuria and necrotic papules.

To identify the developmental characteristics of intermediate filaments, the expressions of various cytokeratines (CK), desmin and vimentin in fetal (14032 weeks of gestations) and adult epidermis were studied immunohistochemically. The primary antibodies used were CK7, 8, 10, 14, 18, AE8, 5D3, and MNFl16 for cytokeratins, D33 for desmin, and V9 for vimentin. At 14 weeks of gestation, the epidermis consisted of basal cells and periderm. The periderm exhibited positive staining for CK8 and AE8, and weak staining for MNF116 and D33. The basal cells showed positive staining for MNF116 and D33. The epidermis did not reacted for CK7, 10, 14, 18, 5D3, and V9 at this period. At 16-20 weeks of gestation, the epidermis was composed of basal, intermediate, and periderm layers. The periderm was positive for CK8, 18, AE8, MNF116, and D33. The intermediate cells were positive for CK10 and the basal cells CK14, MNF116, and D33. Few cells were stained positively with V9 among the basal cells. At 24-32 weeks of gestation, the epidermis exhibited no longer positive reactions for CK8, 18, AE8 and D33. The intermediate cells were positive for CK10. Immunoreactivity for MNF116 was noted in intermediate layer just above the basal layer. CKl4, MNFl16, D33, and often V9 were expressed in basal cells. The expressions of CK7 and 5D3 were not observed at any period of gestation. In adult epidermis, basal cells exhibited positive staining for CKl4, MNFl16, and D33. The intermediate cells were strongly positive for CK10, and weakly positive for CK7, 8, and MNFl16. The cells positive for V9 were often present among the basal cells. These results indicate that CK8 and 18 may serve as useful markers for periderm, CK10 for intermediate cells, CKl4 for basal cell, and suggest that the vimentin immunoreactive cells in basal cell layer are Langerhans cells.
