Congenital adrenal hyperplasia is inherited disorder of adrenal steroidogenesis. 21-hydroxylase deficiency is the most commone enzymatic defect and is divided into classic and late-onset or nonclassic forms. Both classic non-classic 21-hydrozylase deficiencies are inherited in a recessive manner as allelic variants. But it is rare that happened in twin infants. Chief complaints of affected twins in our case were ambiguous genitalia, hyperpigmentation and dehydrations. They were revealed into hyponatremia, hyperkalemia and increased amount of serum progesterone, 17-hydroxyprogesterone and urinary 17-ketosteroid excretion and were administered with DOCA, 9alpha-fluorohydrocortisone, hydrocortisone to control the electrolyte imbalance. And now, both of them are going to normal ratio of weight gain and body growth.

The force-interval relationship of cardiac muscle has been known as not only a fundamental manifestation of beat-to-beat kinetics of intracellular activator calcium which control contractile response but also a potential clinical tool for evaluating cardiac contracile function. In this study were evaluated the force-interval relationship of intact canine left ventricle through mechanical restitution curves by plotting contrctile responses to varying steady state, extrasystolic and postextrasystolic intervals, and compared the force-interval relationships of intact canine left and right ventricles quantitatively. Effects of localized myocardial ischemia on the left ventricular force-interval relationship and relaxtion function were also evaluated 30 minutes after ligating proximal left anterior descending coronary artery through observing contractile and relaxtion responses to various intervals. 1) Mechanical restitution curve of left ventricle showed that left ventricular dp/dt max responses rose stiffly until plateau level with increasing postextrasystolic intervals, then declined with further increment of postextrasystolic intervals. 2) Mechanical restitution curve of left ventricle shifted leftward and upward with shortening of steady state and extrasystolic intervals, which suggest intracellular calcium kinetics during electrical diastole may operate as a mechanism of the force-interval relationship. 3) Steady state contractile responses remained unchanged but maximal contractile responses increased significantly or contractile reserve in intact left ventricle. 4) Normalized force-interval relationships of left and right ventricle were similar quantitatively, which suggest the force-interval relationship is independent of structural factors in intact canine heart. 5) Occlusion of coronary artery lowered absolute values of left ventricular dp/dt max responses to varying postextrasystolic intervals, but didn't show significant changes of normalized dp/dt max responses, which suggest force-interval relationship be also present in spite of localized myocardial ischemia. 6) Responses of normalized left ventricular dp/dt min to varying postextrasystolic intervals were similar to those of normalized dp/dt max but reduced after coronary artery occlusion in the range above 100% dp/dt max response, which may be used for the detection and evaluation of deranged myocardial relaxation in the left ventricle with localized myocardial ischemia.

BACKGROUND: There has been a growing realization that a variety of anticancer drugs can induce apoptotic cell death. In the present study, an attempt was made to investigate the responsiveness of gastric cancer cells to various anticancer drugs and to identify which apoptosis-related proteins could be correlated to chemosensitivity. METHODS: Nine human Korean gastric cancer cell lines (SNU-1, -5, -16, -484, -601, -620, -638, -668, and -719) were analyzed. The cytotoxicity of each cell line to camptothecin, cisplatin, mitomycin C, vincristine, 5-FU, epirubicin, and doxorubicin was determined by using a MTT (dimethylthiazole- diphenyltetrazolium-bromide) assay. Apoptosis-related proteins (p53, p21, Bcl-2, Bcl-x, and Bax) were detected using a Western blot assay. RESULTS: Of the nine gastric cancer cell lines, SNU-1 was resistant while SNU-5 was sensitive to anticancer drugs. Mutated p53 was detected in all the cell lines. The highest expression of Bcl-2 was observed in SNU-1 while less or no expression of Bcl-2 was observed in SNU-5, -484, and -601. Bcl-xL was less expressed in SNU-5 than in the other cell lines. CONCLUSIONS: Chemosensitivity in gastric cancer cell lines was correlated mainly with the level of Bcl-2 and partly with that of Bcl-xL. There was no correlation between the chemosensitivity and other apoptosis-related proteins, such as p21, p53, Bax, and Bcl-xS in the studied gastric cancer cell lines.

BACKGROUND: Apoptosis can be induced by various anticancer agents. Resistance to apoptosis may play an important role in tumors refractory to chemotherapy. The authors investigated both the induction of apoptosis by camptothecin, a topoisomerase I inhibitor, in gastric cancer cell lines and the roles of apoptosis-elated gene products. METHODS: Two gastric cancer cell lines, SNU- and SNU-6, were examined for response to chemotherapeutic agents. Cytotoxicity was determined by a MTT assay. Apoptosis was measured by a DNA fragmentation assay using agarose gel electrophoresis and electron microscopy. Apoptosis-elated gene products were determined by western blot analysis. RESULTS: The two gastric cancer cell lines (SNU- and SNU-6) showed different sensitivities to camptothecin. Apoptosis of SNU-6 was easily induced by camptothecin, while SNU- was refractory to apoptosis, which was confirmed by DNA fragment assays and electron microscopy. Western blot analysis revealed that the amount of Bcl- in SNU- was 2.68-imes more than that in SNU-6. There were no differences in the levels of Bax, Bcl-L, Bcl-s, and p53 between the two cell lines. CONCLUSIONS: It is thought that Bcl- may play an important role in blocking cell death due to anticancer drugs in gastric cancer cell lines. Thus, chemosensitivity might be increased if this cell death-locking status were to be modified by new biologic therapies for gastric cancer.

In an attempt to define quantitatively the relation between left atrial size and atrial fibrillation, echocardiography was used to study 58 patients with mitral stenosis and sinus rhythm, 22 patients with mitral stenosis and newly appeared atrial fibrillation, 62 patients with mitral stenosis and atrial fibrillation, 14 patients with sinus rhythm who undergone mitral valve replacement, 18 patients with atrial fibrillation who undergone mitral valve replacement,17 patients with idiopathic atrial fibrillation and 22 control persons. In all groups of mitral stenosis, atrial fibrillation was rare when left atrial dimension was below 40mm but common when this dimension exceeded 40 mm. When left atrial dimension exceeded 50 mm, sinus rhythm was rare even in patients who undergone mitral replacement operation. These data suggest that left atrial size is an important factor in the development of atrial fibrillation. To reduce the risk of systemic embolism complicating atrial fibrillation and to reduce the need of long term anticoagulant therapy postoperatively, the left atrial dimension should be followed closely for the patients with mitral stenosis.

Plasmodium vivax malaria re-emerged in South Korea in 1993, and epidemics continue since then. We examined genetic variation in the region encompassing the apical membrane antigen-1 (PvAMA-1) of the parasites by DNA sequencing of the 22 re-emerging P. vivax isolates. The genotype of the PvAMA-1, which was based on sequence data previously reported for the polymorphic regions, showed that two haplotypes were present at one polymorphic site. Compared with reported data, the two types, SKOR type I and type II, were similar to Chinese CH-10A and CH-05A isolates, respectively. Thus, the present study showed that two genotypes of AMA-1 genes coexist in the re-emerging Korean P. vivax.

Chronic mitral regurgitation may be well tolerated for decades because of favorable conditions like increased preload and decreased afterload. However, in some patients with underlying overt myocardial dysfunction, opertive correction of mitral regurgitation may result in persistent left ventricular dysfunction. Myocardial dysfunction in mitral regurgitation initially occurs subclinically and may becoma irreversible before symptoms of congestive heart failure develop. In order to identify latent myocardial dysfunction, we evaluated prognostic values of several indices from patient's characteristics, echocardiogram, cardiac catheterization data and contrast left ventriculogram in 49 patients with chronic mitral regurgitation who received mitral valve replacement. The patients were defined as Groups I who had improved symptoms with decreased left ventricular end-diastolic dimension after operation and Group II who had persistent symptoms and progressed left ventricular end-diastolic dimension, or not decreased until left ventricular end-diastolic dimension 60mm after operation. The results were as follows: 1) There was no significant difference in age, sex, duration of symptoms, preoperative NYHA functional status, and aortic cross clamping time during operation between Group I and Group II. 2) There was no significant difference in echocardiographic left ventricular end-diastolic dimension between group I and group II. There were significantly more dilated left ventricular end-diastolic dimension of Group II than that of Group I and significantly more depressed fractional shortening of Group II than that of Group I. There was significantly more increased end-diastolic wall stress of Group II than of Group I. 3) There was no significant difference in cardiac index, mean pulmonary artery pressure, mean pulmonary capillary wedge pressure and left ventricular end-diastoic pressure between Group I and Group II. 4) There were significantly more increased end-diastolic volume index and end-diastolic volum index of Group II than those of Group I, but no significant difference in ejection fraction between Group I and Group II. There was significantly more decreased ratio of end-diastolic circumferential midwall stress to end-diastolic volume index of Group II than that of Group I. 5) In Group I, end-systolic dimension, end-systolic dimension and end-systolic wall stress were decreased significantly after operation. In Group II, end-systolic dimension was decreased significantly after operation. 6) Values for combination of end-systolic left ventricular dimension greater than 28mm/m2 and end-systolic wall stress greater than 190mmHg predicted a Group II outcome with a sensitivity of 88.2%, a specificity of 93.8%, positive predictive value of 88.2% and negative predictive value of 93.8%. Values of combination of end-systolic left ventricular dimension greater than 28mm/m2 and fractional shortening less than 32% predicted a Group II outcome with a sensitivity of 88.2% a specificity of 90.6%, positive predictive value of 83.3% and negative predictive value of 93.5%, a specificity of 90.6%, positive predictive valve of 83.3% and negative predictive value of 93.5%. According to the above results, noninvasive hemodynamic variables such as end-systolic left ventricular dimension, fractional shortening and end-systolic wall stress would be useful guideline for follow-up and determining the optimal time for surgical intervention in patients with chronic mitral regurgitation.
