To evaluate the changes of Doppler echocardiographic parameters of left ventricular(LV) filling in hypertensive subjects, 34 patients(M : F=17 : 17) with and without LV hypertrophy and 19 healthy, age-matched control subjects(M : F=10 : 9) were examined by M-mode, 2 dimensional and Doppler echocardiography. From the Doppler recording, A2 D(time from second heart sound to the onset of early diastolic mitral flow), peak velocity at early diastole(E) and late diastole(A), ratio of E to A velocity, diastolic filling times, early diastolic deceleration rate(EDDR) and flow velocity integral(FVI) were measured. In the patients without LV hypertrophy, A2 D only was significantly prolonged(127+/-21 vs 83+/-24 msec P<0.01) as compared with the normal subjects, but the patients with LV hypertrophy had more prolonged A2 D(149+/-31 vs 83+/-24 msec P<0.01), higher late diastolic peak velocity(A : 0.58+/-0.17 vs 0.47+/-0.09m/sec, P<0.01) and lower E/A velocity ratio(0.95+/-0.19 vs 1.24+/-0.29, P<0.01) than the normal subjects. There was a significant correlation between A2 D and LV muscle mass index in entire patients with hypertension(r=0.42P<0.01). These data suggest that A2D is the earliest parameter indicating abnormality of LV diastolic function and E/A ratio is not likely to be a definite index of LV diastolic dysfunction but rather be a reliable index of LV hypertrophy in hypertensive patients with preserved LV systolic funtion.

BACKGROUND AND OBJECTIVES: The relationship of cold pressor, hyperventilation and exercise test responses to circadian patterns and types of angina in vasospastic angina have still not been known. The aim of this study was to identify subgoups of patients who have similar clinical features and provocation test response. MATERIALS AND METHODS: Twenty-one consecutive patients with pure vasospastic angina were studied. Six exercise tests were performed in the early morning, late morning, and late afternoon in consecutive days, and 2 hyperventilation tests and 2 cold pressor tests in the early morning. Circadian distribution and types of angina(at rest, on physical activity or both) were evaluated by clinical history, clinical records and ambulatory ECG recordings during admission and follow-up periods(mean 19+/-9 months). RESULTS: Three patterns of circadian distribution of anginal attacks were identified during all observation periods together(morning and night: MN n=, morning and afternoon or evening: M+/E n=, morning, night and afternoon and/or evening: MN+/E n=1). Exercise test was positive in 36%(40/111) without circadian variation, hyperventilation test in 66%(23/35) and cold pressor test in 6%(2/33). Neither hyperventilation test nor cold pressor test was related to circadian patterns, types or activity of angina, or numbers of spastic artery. But positive exercise test increased significantly in patients with angina on physical activity(43% vs 21%, p<0.05), high activity(57% vs 18%, p<0.01), multivessel spasm(50% vs 27%, p<0.05 ) and circadian patterns of M+/E and MN+/E(29%, 55% vs 4%, p<0.05, p<0.01). All patients with MN had rest angina and single vessel spasm. All 6 patients with M+/E had angina both at rest and on physical activity and 5 single vessel spasm. Eight of 11 patients with MN+/E had angina both at rest and on physical activity and 8 multivessel spasm. CONCLUSION: These findings suggest that hyperventilation test is highly sensitive in vasospastic angina without any relationship to clinical features, but exercise test response is related well to circadian patterns of angina attacks which are associated with characteristic clinical features.

Sine the success of human growth hormone (GH) synthesis by DNA recombinant technology, these GH products are widely used in the treatment of children with growth hormone deficiency. Recently, methionyl-GH has been produced in the yeast, Saccaromyces cerevisiae 2150, by the use of a DNA recombinant method in Korea. The purpose of this study was to investigate the clinical efficacy, side effect and immunogenicity of this GH product during therapy of 3year in 22 children with naive GH deficiency. The subjects of this study are aged 4.5~17.9 years, diagnosed by the failure of plasma GH to respond to insulin induced hypoglycemia, arginine and/or clonidine loading and height below -2 standard deviation of mean for their chronological age. Each subjcct received GH 0.45IU/kg/week, intramusculary in 3 devided dose, During treatment, vital signs, height and body weight checked before and every 3 months. Blood count urinalysis, blood chemistry, bone age and measurement of thyroid hormone were performed before, every 3months in year 1, and every 6 months in year 2 and 3. Assay of antibody against GH were performed before, year 1,2 and 3. The height velocity was significantly increased from an average baseline level of 2.9+/-1.1cm/year to 7.9+/-1.9cm/year after the first year, 6.6+/-1.1cm/year during the second year, and 5.9+/-1.2cm/year during the third year of GH treatment. The height standard deviation score for chronological age was decreased from an average baseline of 3.5+/-1.3 to 2.9 1.2 after the first year, 2.7 +/-1.1 during the second year, and 2.5+/-1.2 during the year of GH treatment. The increment in height age was significantly increased from an average baseline of 0.6+/-0.2 year to 1.3+/-0.3 year in year 1, 1.1+/-0.3 year in year 2, and 1.0+/-0.2 year in year 3. The increment in bone age was significantly increased from an average baseline of 0.6+/-0.2 year to 1.2+/-0.2 in year 1, 1.3+/-0.3 year in year , 2, and 1.1+/-0.3 year in year 3. Antibody against hGH was observed in 3 of the 22 patients(13.5%) in year 1 and 1 and in 2 of the 17 patients(17.7%) in year 3. And unwanted side effects were not observed in any of the 22 patients. These results suggest that this yeast derived recombinant methionyl growth hormone appears to be a safe very effective product for treating of children with GH deficiency.

PURPOSE: Differential diagnosis of sexual precocity is important. Sexual precocity, defined as the appearance of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys, was studied to evaluate the sex incidence and etiology of sexual precocity. METHODS: We reviewed the etiology and age incidence of precocious puberty in 14 boys and 89 girls examined between 1994. 11. 1-2002. 7. 31 at Samsung Seoul Hospital. All underwent standard anthropometric measures. They were assigned to diagnostic categories on the basis of clinical assessment, endocrine evaluation, radiologic imaging, and pelvic ultrasonography. RESULTS: In 89 girls, 27 had idiopathic precocious puberty, 3 had precocious puberty with organic brain lesion, 12 had gonadotropin-independent precocious puberty, 44 had premature thelarche, 2 had premature menarche, 1 had premature adrenarche. The majority of idiopathic precocious puberty girls(78%) were aged between 7-7.9 years. In 14 boys, 2 had idiopathic precocious puberty, 3 had precocious puberty with organic brain lesion, 6 had gonadotropin-independent precocious puberty, 3 had gynecomastia. CONCLUSION: Sexual precocity occurs more frequently in girls than boys. Premature thelarche is the most common form of sexual precosity. In boys, majority of central precocious puberty had organic brain lesion, so brain imaging study should be performed. In girls, majority of idiopathic precocious puberty were aged between 7-7.9 years. Reexamination of the age limit for defining when puberty should be considered precocious in Korean girls is necessary.
