Idiopathic calcinosis of the scrotum consists of multiple asymptomatic nodules of the scrotum without any underlying disease. We presented a case of idiopathic calcinosis of the scrotum and compared it with other reported cases in Korea, A 47-year-old farmer had slowly growing, asymptomatic, hard scrotal nodules which were 1cm in diameter and 6 in number for about twenty years. KUB X-ray film showed two radiopaque densities on the scrotal area. Histopathological finding revealed amorphous, basaphilic masses with acicular clefts which were confirmed as calcification in Von Kossa stain and surrounding foreign body granulomatous inflammatory reaction.

Dermstomyositis is a disease mainly of the skin, muscle and blood vessels in which erythematous and edematous changes in the skin are associated with muscle weakneas and inflammation. In adult the disease is commonly associated with underlying malignancy or reticulosis. A 23 year-old male had generalized weakness, intermittent fever, myalgia and purplish red patches on the face. Diagnosis of dermatomyositis was established by clinical manifestations, electromyogram, histologic findings of skin and muscle. He was treated with systemic steroid, with some improvement. Seven months after the onset of dermatomyositis, ecchymoses was noted on the eyelids and forearms. Bone marrow aspiration showed many immature lymphoblasts, characteristic of acute lymphocytic leukemia, He was treated with systemic steroid and vincristine, but no favorable effect was noted. He died of sepsis due to retal abscess on the 34th day in the hospital

Electrocardiography has been long an important tool in cardiac diagnosis and, with advances in electrocardiography, the accuracy of the electrocardiographic diagnosis has been greatly increased. Though the most accurate methods for quantitative diagnosis of mitral valvular disease are cardiac catheterization and ventriculography, these procedures are time consuming, expensive, and not without risk, thus, it would be helpful if routine catheterization of the heart could be avoided in patients who are potential condidates for mitral valvulotomy. This could be done if reliable electrocardiographic criteria could be found for estimating the amount of obstrcution and leak at the mitral valve. As mitral valvular dysfunction progress, changes (hypertrophy and/or dilation) in the left atrium and both ventricles are inevitable. Many authors attempted to characterize the electrocardiographic findings of such changes according to the specific lesion of the mitral valve. In addition to atrial fibrillation, characteristic P wave changes and their diagnostic significance have been reported (Macruz et al., 1958; Arevalo et al., 1963: Morris et al., 1964). The diagnostic importance of QRS voltage difference in precordial leads has been stressed in the differential diagnosis of specific lesions of mitral valvular disease (Janton et al., 1954: Bateman and January, 1955: Wierum and Glenn, 1957: Bentivoglio et al., 1958: Imperial et al., 1960). Semle and Pruitt(1960) reported that a mean QRS electrical axis of +91degrees or more degrees was the most frequent positive single index of increased total pulmonary resistance in mitral stenosis, and Fowler et al. (1955) stated that precordial lead V1 was very helpful in evaluating the degree of pulmonary hypertension. In Korea there are only a few reports on the electrocardiographic changes in mitral valvular disease and the correlation of electrocardiographic findings and hemodynamics (Oh et al., 1961: Kim, 1970: Kim, 1971). It would be evident that the various electrocardiographic findings noted in western races can't be applied to Koreans. The main objectives of this study are: 1. To determine the electrocardiographic characteristics of pure mitral valvular disease and the differentiation between the specific lesions of pure mitral stenosis, pure mitral insufficiency and combined lesions of mitral stenosis and insufficiency. 2. To know whether the characteristic electrocardiographic changes of mitral stenosis are directly related to the narrowed valve area or to the hemodynamic abnormalities secondary to obstruction. SUBJECTS AND METHODS: 139 cases of isolated mitral valvular disease were reviewed: of these 93 were cases of pure mitral stenosis, 18 were pure mitral insufficiency, and 28 were combined mitral stenosis and insufficiency. Of the total patients, 68 were male and 71 were female. The ages ranged from 10 to 54 years with an average of 35.6 years. Diagnosis was based on cardiac catheterization and supplemented by cienangiocardiography. The conventional 12 lead electrocardiogram was taken at normal sensitivity and at a paper speed of 25mm/sec. The mitral valve area was estimated according to the Gorlin's formula and cardiac output was determined by the direct Fick's principle. The electrocardiograms were analyzed with respect to: 1. Rhythm (atrial fibrillation and sinus rhythm) 2. Presence or absence of P-mitrale 3. Terminal P force in lead V1 (by the method of Morris et. al., 1964) 4. Mean QRS electrical axis in frontal plane 5. QRS voltage in percordial leads(V1S, V5R, V6R & V1S+V(5-6)R) 6. R/S ratio in lead V1 7. Conduction disturbance of right bundle branch block In patients with pure mitral stenosis the electrocardiographic findings of atrial fibrillation P-mitrale, terminal P force in lead V1 were correlated with the hemodynamic data of mean pulmonary artery pressure, mean pulmonary arterial wedge pressure and mitral valve area. An attempt was made to ascertain whether or not a quantitative correlation could be found. A patient showing electrocardiographic pattern of right bundle branch block was excluded in the evaluation of QRS voltage in lead V1 and mean QRS electrical axis in frontal plane. RESULTS AND SUMMARY: 1. P wave abnormality, which was noted in most (131/139) cases, is apparently a characteristic and most frequent electrocardiographic finding in mitral valvular disease. Of the P weve abnormalities the development of atrial fibrillation and P-mitrale were thought to be related to the duration of the illness rather than to the types of lesion or hemodynamic abnormalities secondary to valvular dysfunction. However, the terminal P force in lead V1 was thought to be related to the mean pulmonary arterial wedge pressure rather than to narrowing of the valve. 2. 15 patients showed the electrocardiographic pattern of right bundle branch block. In patients with mitral stenosis this electrocardiographic pattern was noted at almost all levels of mean pulmonary artery pressure, mean pulmonary arterial wedge pressure, mitral gradient and mitral valve area. 3. Mean QRS electrical axis and QRS voltage in precordial leads; There was no case which deviated leftward more than +30degrees even among cases with a predominant or pure mitral insufficiency. Although the difference of mean value in mean QRS electrical axis and QRS voltage in precordial leads according to the types of the lesion was significant, this difference was generally not helpful in the differential diagnosis in individual patients because of much overlapping among cases. 4. There was no definite electrocardiographic criteria to differentiate clearly the types of mitral valvular disease. However, the following aspects of electrocardiogram may be useful in differential diagnosis. a. Difference of QRS voltage in precordial leads: The volage of V1S and V1S+V(5-6)R in all patients with pure mitral insufficiency was over 1mm and 11mm respectively. That of V1S+V(5-6)R in all patients with pure mitral stenosis was below 39mm. b. R/S ratio in lead V1: There was no case showing "R wave only" in lead V1 among patients with pure or predominant mitral insufficiency. c. Mean QRS electrical axis in frontal plane: The mean QRS electrical axis of all patients with pure mitral stenosis deviated rightward more than +60degrees in all except one case. None of the patients with pure mitral insufficiency deviated rightward more than +110degrees. 5. Relationship between hemodynamics and electrocardiography in paitents with mitral stenosis: Among the hemodynamic abnormalities, mean pulmonary artery pressure showed a close relationship with the following aspects of the electrocardiogram. a. R/S ratio in lead V1:The mean value of mean pulmonary artery pressure (45.9+/-3.8mmHg) in groups showing R/S>1 was significantly elevated as compared with that (34.8+/-1.5mmHg) of groups showing R/Sdegrees1. b. Mean QRS electrical axis in frontal plane: There was a weak positive correlation (r=+0.53) between mean pulmonary artery prersure and QRS electrical axis in the frontal plane. The QRS axis of all patients with a mean pulmonary artery pressure of 41mmHg or more was +91degrees or more except for one case. c. Terminal P force in lead V1: The difference of mean value in mean pulmonary artery pressure according to the size of terminal P force in lead V1 was significant in all cases.

BACKGROUND: The Chinese hamster ovary cells transfected with human TSH receptor cDNA (hTSHR-CHO), expressing functional human TSH receptors, are known to be more sensitive in detection of thyroid stimulating antibodies than FRTL-5 cells. There has been no report on the usefulness of these cells to measure thyroid stimulation blocking antibody (TSBAb) activity which is frequently found in patients with primary myxedema, METHODS: We established the optimal assay condition of measurement of TSBAb using hTSHR-CHO cells, and simultaneously measured TSBAb activities with FRTL-5 cells and with hTSHR-CHO cells in 49 patients with primary myxedema, compared them with their thyrotropin binding inhibitor immunoglobulin (TBII) activities. RESULTS: 1) hTSHR-CHO cells specifically bound bTSH and were stimulated by bTSH in terms of cyclic AMP generation in a dose dependent manner. 2) Myxedema IgG suppressed TSH-stimulated cAMP production of hTSHR-CHO cells in a dose dependent manner reaching plateau at the concentration of I g/L. Normal pooled IgG has no suppressive action at the concentration of less than 1 g/L, but caused significant suppression at the concentration of greater than 1g/L. 3) TSBAb activities measured by hTSHR-CHO cells in 49 patients with primary myxedema were as follows: Four of 25 TBII-negative cases (16%) and 22 of 24 TBII-positive cases (92%) had TSBAb activities. Most of TSBAb positive patients (95%), especially in TBII positive cases, showed very high activities of more than 90%. 4) TSBAb activities measured by hTSHR-CHO cells and those by FRTL-5 cells were both positive in 24 patients (49%), both negative in 18 patients (37%), and were discrepant in 7 patients (14%). The TSBAb activities measured with hTSHR-CHO cells and those measured with FRTL-5 cells were significantly correlated (r=0.71, p< 0.01). 5) Forty five percent of patients with primary myxedema had all of 3 kinds of activities (TBII, hTSHR-CHO cell TSBAb, FRTL-5 cell TSBAb), 37% of them had none of 3 activities and 18% of them had 1 or 2 kinds of activities only. CONCLUSION: The usefulness of hTSHR-CHO cells in measurements of TSBAb activities were confirmed. The TSBAb activities of most patients with primary myxedema measured by hTSHR-CHO cells were concordant with those measured by FRTL-5 cells. However, a small subset of patients (18%) had discrepant results in assays of TSH receptor antibodies according to the differences in TSH receptors (rat, human and porcine) used in assay. Such discrepancy may be explained by heterogeneity in epitopes for blocking TSH receptor antibodies.

A total of 135 strains of M canis, composed of 1R4 from the patients and 1 from an infected pet cat, were crossed with the 2 tester strains of eVannizzia otae VUT 77054 "/" and VUT 77055 "-" supplied by Dr. A. Hasegawa. These 134 human strains were originated from 77 casea of tinea capitis, 20 of tinea faciei and 37 of tinea corporis from Taegu city, Kyungpook and neighboring provinces during the period from December 1975 to August 1982. Out of 134 hurnan isolates, 112 (83. 6%) were of "-" mating type of N. otae and 22 (16.4%) were nonreactive. None were compatible with the + mating type. One strain from a pet cat proved also to be of type. The majority of the tested strains were revealed to be sexually degenerated.

The authors studied the plasma cholesterol levels in 39 rats (Sprague-Dawley) after 4 weeks administration of etretinate and/or fish oil. The study groups were as follows.'13 rats recieved etretinate only;13, fish oil only;13, both ertetinate and fish oil. Cholesterol levels were determined by standard enzymatic methodology. The results were as follows. Tot,al-cholesterol levels in rats following administration of ertetinate only were increased(p<0.05), but the levels in rats receiving fish oil only and both etretinate and fish oil were markedly decreased(p<0.01). HDL-cholesterol levels in rats following administration of fish oil and both etretinate and fish oil were decreased(p<0.01). The ratio of HDL-cholesterol to total-cholesterol in rats receiving fish oil only and both etretinate and fish oil were increased(p<0.05) because of markedly decreased total-cholesterol levels.
