The electrocardiographic and echocardiographic analysis was made on 23 patients with atrial septal defect of ostium secundum type, who were confirmed by right heart catheterization under admission at hanyang University Hospital from january 1979 to July 1981. Following results were obtained: 1) In the 23 patients, 13 were male and 10 female. Their ages ranged from 6 to 45 years, mean age being 19.9 years. 2) In 18 patients(78.3%), the QRS axis was between +90degrees and +150degrees. No significant correlations could be demonstrated between QRS axis and some hemodynamic parameters(right ventricular systolic pressure, pulmonary artery mean pressure and pulmonic to systemic flow ratio), and also, between QRS axis and the size of right ventricular dimension index. 3) Right ventricular outflow tract hypertrophy, right ventricular hypertrophy and complete right bundle branch block pattern in Lead V3R or V1were observed in 95.7% of ostium secundum defect. No significant correlations could be found between types of QRS complexes and some hemodynamic parameters(right ventricular systolic pressure, pulmonary artery mean pressure and pulmonic to systemic flow ratio), and also, between types of QRS complex and the size of right ventricular dimension index. 4) The mean amplitude of S wave in precordial Lead V6was 7.6mm. There was a definite correlation between the amplitude of S wave in Lead V6and right ventricular systolic pressure. No significant correlations could be demonstrated betwen the amplitude of s wave in Lead V6and some hemodynamic parameters(pulmonary artery mean pressure and pulmonic to systemic flow ratio), and also, the size of right ventricular dimension index. 5) Right ventricular dimension index was increased in all cases but one. A significant correlation was found between the size of right ventricular dimension index and pulmonary artery mean pressure, whereas no significant correlation could be demonstrated between the size of right ventricular dimension index and pulmonic to systemic flow ratio. 6) 95.7% of 23 patients with ostium secudum defect showed paradoxical septal motion was proved not to be associated with other congenital heart disease by cardiac catheterization. The pulmonic to systemic flow ratio in groups of septal motion type A was significantly increased than that of normal septal motion group, whereas no significantl relation between types of septal motion and the size of right ventricular dimension index was observed.

We investigated the biochemiesl change of keratin by the methods of SDS-PAGE and Two-dimensional gel electrophoresis, and observed electron microscopic ultrestructural changes in five Unna-Thost palmoplantar keratoderma patients and two normal adults. The results are summarized as follows : 1. The increased bands of 51 kd and newly appearing 48 kd, 56 kd keratins were observed on the SDS-PAGE and compared to the normsl control. 2. The newly appearing 48 kd(acidic) paired with 56 kd(basic) keratins and 51 kd keratin and the disappearance of 59 kd(basic), 64 kd(basic) keratins were observed on the two-dimensional gel electrophoresis and compared to the normal control. 3. The variable sized, numerous, globular, irregularly beam-shaped and granular kerstohyaline granules were scattered in the granular cell and corneocyte. Numerous ribosomes were noted between the clumped tonofibrils and around the keratohyaline granules. The lipid droplets were seen in the corneocytes and granular cells on the electron microscope.

"Cutaneous horn", the clinical term first defined by Moncorps in 1931, has been used to describe those markedly hyperkeratotic growths resembling the horns of animals in shape and hardness. Recently, we observed a typical case of cutaneous horn in a 13-year-old child. He had a finger-tip sized, yellow-brown, hard, protruding tumor with surrounding erythema on the right little finger for 2 years. On microscopic examination, the biopsy specimen from the squamous epithelium of tbe base showed a typical verruca vulgaris. Total excision and skin graft were performed under general anesthesia.

Ventricular premature beats(VPB) are the most common cardiac arrhythmia and frequently found in apparently normal healthy persons as well as in various heart diseases. Postectopic potentiation of ventricular contraction has widely reported by electrocardiography. In this study, the authors performed comparative assessment of the left ventricular function at the preextrasystolic, extrasystolic and postextrasystolic beats by M-mode echocardiography and electrocardiography. The results obtained were as followings; 1) Among 22 patients of isolated, unifocal ventricular premature beats with fully compensatory pause, male were 6 and female 16, mean age being 47.2 years. 2) Hypertensive heart disease was the most common underlying disease of ventricular premature beats(5 patients) and the others were valvular heart diaeases(3), ischemic heart diseases(3), cardiomyopathy(2), intracerebral hemorrhagy(1), atrial septal defect of secundumtype(1), cor pulmonale(1), pericarditis(1), 1degree A-V block(1) and enteric fever(1). In 3 patients the causes were not clarified. 3) R wave amplitude was higher in the postextrasystolic beat(2.02+/-0.79cm) than preestrasystolic beat(1.86+/-0.66cm) 4) PEP/LVET ratio showed more decrease(18%) in postextrasystolic beat than that of preextrasystole. 5) Diastolic filling time of mitral valve was more reduced in the extrasystole than preextrasystole, but that of postextrasystole exceeded the preextrastystole. 6) Aortic cusps separation was more decreased in the extrasystole than preextrasystole and slightly more increased in the postextrasystole than preextrasystole. 7) LVID, LSa, ENa, DeltaEN/Deltat, LVEDV, SV and LV mass showed more decrease in extrasystole compared with those in pre-and postextrasystole, which was higher than preextrasystole. But LVESV was slightly lower in extrasystole than preextrasystole. 8) In extrasystolic beat, LVEDV, LVESV, stroke volume, and ejection fraction of ventri cular premature beat were 15.77%, 0.18%, 24.05% and 12.21% lower, respectively, than those of preextrasystole. And in the postextrasystole, LVEDV, LVESV, stroke volume and ejection fraction were 23.35%, 2.42%, 28.51% and 10.4% higher, respectively, than these of preextrasystole.

Holter ECG monitoring is a continuous tape recording of a patient's electrocardiogram during ordinary activities and picks up hidden abnormalities in rate, rhythm or conduction. The authors delineated the types and incidence rates of arrhythmia in 32 normal Koreans by utilizing medical personnels and patients without evident heart diseases or symptoms, or significant systemic illness. Tracings and analysis were performed using 24 hour Holter monitoring processor(SCM 240, Fukuda, japan), auto-analyser (SCM-25), casette recorder(SM 24) and chrome tape. Results are as follows: 1) Portable 24 houre Holter ECG monitoring was performed in 32 persons(age range of 21 to 35) without cardiovascular disease, as defined by normal clinical and noninvasive cardiovascular examination. 2) During exercise, maximal heart rates ranged from 125.0+/-12.1/min and minimal rates from 96.7+/-5.8/min. During normal activity period, maximal and minimal heart rates were, respectively, 95.4+/-16.2/min and 62.6+/-6.3/min. Maximal sleep rates were 90.3+/-26.6/min and minimal sleep rates 57.4+/-12.4/min. 3) P-R interval decreased as heart rate increased. Transient first degree AV block was noted in 3 subjects(9.4%) and Wenckebach type second degree AV block in 2 subjects(6.3%). 4) Sinus tachycardia and bradycardia were observed in all subjects and sinus arrhythmia was more frequently noted during waking periods. Three subjects had episodes of sinus pause with maximum duration of 3.24 seconds. 5) In 13 persons(40.6%) having supraventricular premature beats, the frequency was 50.01+/-49.36/hr and in 14 persons having(44%) ventricular premature beats the frequency 26.33+/-18.83/hr. Transient ventricular tachycardia of 3 seconds' duration was observed in one subject under the extreme stressful environment. 6) ST segment elevation over 1mm was noted in 5 subjects(15.6%), of whom one had a nocturnal chest pain and ST segment depression over 1mm in 2 subjects. T wave inversion was also found during exercise(3.1%) and during sleep(9.4%).

BACKGROUND AND OBJECTIVES: N-cadherin is known to be expressed in neuroectodermal tissue such as central nervous system and various mesodermal origin tissues such as kidney and heart. We investigated N-cadherin expression in the endocardial cushion in developing rat heart by immunohistochemical method. MATERIALS AND METHOD: Fetal rat hearts at the 11th, 13th, 15th, 17th, and 19th day of gestation and the 1st day neonatal rat heart were used. Hematoxylin and eosin stain was performed for normal cardiogenesis, and immunohistochemistry was performed for the expression of N-cadherin in interventricular septum(IVS) during cardiogenesis in rat. RESULTS: Ventricular wall and membranous part of the IVS showed positive reaction with anti-N-cadherin at the 11th day of gestation. Membranous part of IVS was begun to show tracely positive reaction at the 15th day of gestation, and thereafter the immunoreactivity was increased with maturation. At the 17th day of gestation mesenchymal cells in membranous muscular part of the IVS showed positive reaction. The similar immunoreactivity of membranous and muscular parts of IVS were shown at the 19th day of gestation. CONCLUSION: As the immunoreaction of mesenchymal cells in the membraneous part of IVS to anti-N-cadherin was increased with time, it is suggested that mesenchymal cells in membranous part of IVS were differentiated into the cardiomyocytes.

The authors reported here a 23 years-old female patient with acute renal failure and anaphylaxis induced by rifampicin, who was suffered from exudative pericarditis. The diagnosis was made by its reproducibility with rifampicin. The pathogenesis of acute renal failure and anaphylaxis in this case was thought to be immunologic mechanism, because of elevated IgE and depressed complements. Relevant literature was also reviewed.

Heart failure is a recognized, although uncommon, cause of massive liver cell necrosis, the clinical consequence of which are intermingled with those of cardiac insufficiency in most case. But, hepatic coma is rerely caused by hepatic congestion only. We report the three cases with heart failure resulted in massive liver cell necrosis and fulminant hepatic failure. The manifestations of fulminant hepatic failure were hepatic encephalopathy, jaundice, marked increase of prothrombin time and serum transaminase and there were no evidences of viral hepatitis and toxic hepatitis as a cause of liver failure.
