OBJECTIVE: It is widely accepted that the estrogen plays an important role in the maintenance of bone mineral density (BMD). The purpose of this study is to compare the BMD between premature ovarian failure (POF) patients and spontaneous menopausal women, both of which are characterized by estrogen deficiency. METHOD: We compared the BMD of Lumbar 2-4 and Femur neck(right) measured by dual energy X-ray absorptiometry in 17 premature ovarian failure patients and 21 spontaneous menopausal women. RESULTS: POF patients and spontaneous menopausal women showed the BMD of 1.000+/-0.165g/cm2, 1.167+/-0.279g/cm2 at Lumbar 2-4 and 0.793+/-0.132g/cm2, 0.885+/-0.128g/cm2 at Femur neck, respectively. POF patients had lower BMD of Lumbar 2-4 and Femur neck significantly(p<0.05). FSH and estradiol level were not different between the two groups. CONCLUSION: This study demonstrated that the BMD in POF patients was decreased more severely than that of spontaneous menopausal women. Therefore, more preventive measures against bone loss is required in POF patients than spontaneous menopausal women.

The isolated coronary ostial stenosis is a lesion of the aortic wall that encroaches on the orifice of the left main coronary artery, atherosclerosis is belived to be a common cause and premenopausal female patients are most commonly affected. Stenosis of the left coronary ostium is a critical lesion which requires urgent myocardial revascularization including a surgical intervention because this lesion jeopardizes such a large volume of left ventricular myocardium. We report the case of a patient in whom percutaneous transluminal coronary angioplasty (PTCA) was performed successfully for the stenotic lesion of distal anastomotic site after surgical ostioplasty with autologous pericardium.

Impaired endothelium dependent relaxation occurs in diabetic rabbit corpus cavernosum and normal corpus cavernosum exposed to elevated glucose. Elevation of glucose can change the activities of two key enzymes, protein kinase C (PKC) and Na+-K+ ATPase. This study addresses the question of whether impaired endothelium dependent relaxation in isolated corpus cavernosum from normal rabbit exposed to elevated glucose is related to PKC and Na+-K+ ATPase activities and, if so, whether it is associated with altered ouabain sensitive 86-Rb uptake, an index of Na+-K+ ATPase activity, and contractile response of corpus cavernosum tissue to ouabain. Corpus cavernosal tissue suspended for measurement of isometric tension were incubated for 6 hours in control (5.5mM) or elevated glucose (44mM) to mimic euglycemic and hyperglycemic conditions. Relaxations of corpus cavernosum tissue in response to the endothelium-dependent vasodilator acetylcholine (ACh)were unaffected in control groups while significantly inhibited in the elevated glucose group. Relaxations of corporeal tissue to endothelium-independent vasodilators, sodium nitroprusside (SNP) were similar in the control and elevated glucose groups. Corporeal tissue treated with 4-phorbol 12-myristate 13-acetate (PMA), a PKC activator, showed decreased relaxations to ACh, similar to normal corporeal tissue exposed to elevated glucose. Relaxations in response to SNP were unaffected by treatment with PMA or exposure to elevated glucose. 1(5-isoquinolinylsulfonyl)-2-methylpiperazine (H-7), PKC inhibitor, restored the abnormal Ach-induced relaxation in corporeal tissue exposed to elevated glucose. The contractions caused by ouabain, Na+-K+ ATPase inhibitor, were smaller in elevated glucose groups than control and elevated glucose groups treated with H-7. Ouabain sensitive 86-Rb uptake of elevated glucose groups was significantly less than that of control groups but ouabain sensitive 86-Rb uptake of elevated glucose groups treated with H-7 was similar to those of control groups. These results suggest that activation in PKC activity and inhibition in Na+-K+ ATPase activity caused by elevated glucose contribute to impaired endothelium dependent relaxation in corpus cavernosum smooth muscle.

OBJECTIVE: The purpose of this study attempts to determine the endocrinologic characteristics and changes in glucose metabolism before/during pregnancy according to different body weights in women with Polycystic ovarian syndrome (PCOS). METHODS: 94 women dia with PCOS were evaluated through measuring serum hormone levels and oral glucose tolerance tests preconceptionally and gestationally. RESULTS: In patients who were of normal weight showed significantly increased serum LH levels compared to those who were overweight (12.8+/-0.9 Vs. 7.1+/-0.8 mIU/ml, p= 0.000), and the serum levels of insulin was increased significantly in the overweight group (7.1+/-0.7 Vs. 15.2+/-2.8 ulU/ml, p= 0.000). the IGFBP-I (32.8+/-10.6 Vs. 8.3+/-2.5 ng/ml, p=0.034) and SHBG (55.8+/-4.2 Vs. 37.1+/-3.1 nmol/ml, p= 0.001) were significantly lower in the ovnweight group. The oral glucose tolerance test before/after pregnancy showed increased frequency of abnormal glucose metabolism, in both of the non-obese group (38.8%, 26,9%) and the obese group (64.2%, 53.9%) compared with normal population. CONCLUSION: It is thought that in the normal weight group with polycystic ovarian syndrome androgen production is stimulated in the theca cells by abnormally high LH secretion, while in the overweight group the hyperinsulinemia state which decreases the SHBG and IGFBP-I, lead to increase biologically active hee androgens and IGF-I and increase insulin binding to its receptor. And during/before pregnancy, women with PCOS showed that incidence of abnormal glucose metabolism was significantly increased in both of non-obese and obese groups.

This study was carried out to investigate the heavy metal contents and their correlations between paddy soil and brown rice near the Kum-River area. In this study, eighty soil samples and forty brown rice samples were taken from the paddy soil. The contents of heavy metals were measured by flame atomic absorption spectrophotometry. The results were as follows: 1. The average contents of soluble heavy metals in surface soil were Cd 0.19, Cu 15.31, Zn 18.10 and Pb 9.08 ppm. The average contents of soluble heavy metals in subsurface soil were Cd 0.19, Cu 14.52, Zn 17.75 and Pb8.11 ppm. There wan no statistically significant difference between the two layers. 2. The contents of Cu, Zn and Pb of Taejeon(S6) and Cd of Sinbyung(S5) in surface soil were higher than those of other areas. The contents of Cd and Cu of Taejeon(S6) and Zn and Pb of Kumnam(S3) in brown rice were higher than those of other areas and four heavy metals in soil and brown rice of Simchon(S7) were lower than those of other areas. 3. The ratio of soluble contents(Cd : Cu : Zn : Pb) in surface soil was 1 : 79 : 93 : 47, that of soluble contents in subsurface soil was 1 : 79 : 94 : 43, and that of total contents in brown rice was 1 : 84 : 294 : 12. 4. The correlations of the content between soluble heavy metals in surface(0-15 cm depth) soil total heavy metals in brown rice was found to be order of Cd>Cu>Zn>Pb. The correlations of the content between soluble heavy metals in subsurface(20-30 cm depth) soil and total heavy metals in brown rice was found to be order of Cu>Cd>Zn>Pb.

BACKGROUND: Effective evaluation of an article's scientific merit requires familiarity with the methodology described, especially when quantitative techniques, such as statistical procedures, are invoked to clarify research findings or to summarize data. OBJECTIVE: The purpose of this study was to describe the frequency with which various statistical concepts were reported in journals important to dermatology. From these results, dermatologists can identify the major statistical skills needed to critically evaluate their literature. METHODS: All 376 original articles of the Korean Journal of Dermatology(KJD) and the Annals of Dermatology(KAD) during 1990-1994 were chosen for review. Each article was re-viewed to determine the statistical content. RESULTS: The two most commonly used statistical techniques in the two journals were mean and standard deviation. The t-test was the next most frequently used statistical technique in the reviewed journals, followed by non-parametric, chi-square test, orphan p, ANOVA, and correlation/regression. CONCLUSION: These results indicate the need for wider education about the use of descriptive and basic comparative statistics. It is impossible to evaluate the dermatological literature critically without these skills.
