To verify the effect of subgingival calculus on the periodontal tissues in periodontitis and the effectiveness of supragingival scaling to remove the calculus, 30 teeth from healthy group (Probing pocket depth:PPD< or =mm: HP group), 15 teeth from moderate group (4< or =PD<7mm: MP group), 30 teeth from advanced group (PPD>7mm: AP group) were selected and supragingival scaling was performed before extraction of all experimental teeth. After careful extraction, the teeth were cleaned with saline and disclosed with toluidine blue and carefully examined the relationship and distance between the calculus attached on the root surface and periodontal tissues. As a result, it was; 1. The calculus was not discovered on the root surface of teeth in HP group, but was in MP and AP group, mostly on interproximal surface and furca area. The shape of the attached calculus was ovoid, trepazoid and polygonal and the calculus was distributed randomly over the root surface. 2. PPD was more than the distance between the gingival margin to the level of attached connective tissue in AP group rather than in HP and MP group. 3. The length of calculus was 2.7mm+/-.44mm in HP group and 4.1+/-.89in AP group. 4. The distance between the apical margin of calculus and the level of attached connective tissue was 2.4+/-.33mm in MP group and 3.4+/-.89mm in AP group. 5. The length of subgingival calculus was tended to increase in relation to the probing pocket depth. Therefore, it can be concluded, the calculus in periodontal pocket can not be removed completely with supragingival scaling. As the terminal part of calculus was far away with limited distance from the periodontal tissue, it can be said that the calculus was not a direct factor in destroying the periodontal tissue. In this study, the extent of the plaque was not verified but the location of calculus can be used in clinical practice for complete removal of calculus when the distance relation bewteen calculus and plaque will be known.

BACKGROUND AND OBJECTIVES: Imidapril, one of the ACE inhibitor, has been used to treate hypertension, congestive heart failure, diabetes mellitus and renal disease. ACE inhibitor, however often causes dry cough and this adverse effect affects the compliance rate negatively. This report aimed to examine the incidence rate of coughing caused by Imidapril treat-ment. And we compared the results with the incidence and tendency of dry cough caused by the other ACE inhibitors. MATERIALS AND METHOD: This study enrolled 38 patients who followed up at internal medicine and took Imidapril from the period of May 9, 1997 to December 17, 1997. We tested its effectiveness, safety and tolerance. The initial dosage of it was 5mg/day and the maximum dosage according to blood pressure was 10mg/day for 8 weeks. The tendency and the incidence of dry cough have been analyzed and compared with recently published Korean reports. RESULTS: The 5 mg dosage of Imidapril showed 68.1% in lowering blood pressure rate and it went up to 81.8% during the 8 weeks treatment perriod. The blood pressure regularity rate was 36.3% after the 8 weeks treatment. The overall rate of adverse effect occurrence was 26.1% (6/23) and 8.7% of them were likely to cough. One of the patients who showed nausea stopped medication. The recent articles reported that the incidence of dry cough had been reduced: Enalapril (33.8%), Fosinopril (16%), Ramipril (15%), Imidapril (7.8 - 8.7%), Losartan (4.3%). CONCLUSION: Imidapril is as safe and effective as other ACE inhibitors. Various ACE inhibitors that were newly developed show their effectiveness in lessening incidence rate of dry cough, and Imidapril is thought to be an excellent drug for this matter. Even though Losartan shows the lowest incidence rate of dry cough, it needs to more regular usages since it is still on the stage of its medical adaptation.

OBJECTIVES: The purpose of this study is to analyze the previously unreported effect of fetal sex on the fetal heart rate and to measure its magnitude in relation to the effects of other independent clinical variables. METHODS: Three hundred and seventeen pregnant women who were able to provide electronic fetal heart rate monitoring were evaluated. On the basis of fetal sex after birth, 167 pregnant women who delivered male neonate were for males group and 146 examples who delivered female neonate were for female group. We analyzed fetal heart rate data using the Catholic Computer Assisted Obstetric Diagnosis System(CCAOD). RESULTS: Female fetuses had significantly faster basal heart rate(140.51+/-12.43bpm) than male fetuses(137.64+/-13.68 bpm).(P=0.007) Percent acceleration time(PAT) increased significantly for males(6.10+/-4.00bpm), comparing to females(4.90+/-3.34bpm).(P=0.001) Also percent deceleration time(PDT) was significantly higher in male fetuses(7.50+/-8.70bpm) than female fetuses(6.18+/-7.70bpm).(P=0.039) But there was no differences in standard deviation(SD)(8.84+/-10.11bpm, 8.11+/-3.56bpm), long term variation(LTV)(80.38+/-62.79msec, 73.65+/-54.60msec), and short term variation(STV)(14.06+/-9.79msec, 13.33+/-12.32msec) between male and female fetuses. CONCLUSION: The fetal heart rate of female fetuses differ from that of male fetuses. Computerized linear analysis and nonlinear analysis of antepartum fetal heart rate will need to take into account the multiple factors that influence the fetal heart rate to identify precisely which pattern predict clinical outcome.

Patients with achondroplasia manifest various neurologic symptoms including megaencephaly, hydrocephalus, and progressive myelopathy or radiculopathy secondary to spinal stenosis. However, only anecdotal postmortem reports proved ruptured aneurysm or vascular malformation as a source of intracranial hemorrhage. We herein report a case of a 26-year-old woman with achondroplasia who underwent uneventful surgical treatment for the aneurysmal subarachnoid hemorrhage. In this literature, we review the pathophysiologic mechanism and emphasize the necessity of considering the possibility of sudden mental deterioration in achondroplastic patient.

Three-dimensional computed tomographic angiography (CTA), a representative noninvasive radiologic technique, is being widely used for detecting vascular lesions in specific intracranial bleeding under a certain circumstance (acute nontraumatic subarachnoid hemorrhage). We encountered a case of extravasation of the contrast medium on CTA images that appeared as ribbon-like high-attenuation lesion from an aneurysm at the distal anterior choroidal artery in a young adult moyamoya patient. As CTA is used more frequently, it is imperative to understand such unusual but, potentially lethal image findings to conduct a prompt intervention.

Congenital anomalies occur in 2-3% of neonates but this incidence increases in multiple pregnancies, especially when fetuses are monozygotic. when pregnancies are affected with one anomalous fetus combined to a normal one, the proper management and counseling is difficult.We experienced a twin pregnancy in which one anencephalic fetus was combined to a normal one. Karyotype analysis was normal in both fetus. After close counseling we decided to continue the pregnancy. Intermittent amnioreduction was done for persistent polyhydramnios. At 29 weeks of gestation membrane was ruptured prematurely and we delivered by cesarean section due to breech-cephalic presentation. The birth weight of the normal and anencephalic fetuses were 1070 gm and 1050 gm, respectively. The anencephalic fetus died immediately after birth but the healthy one showed good crying and movement and its Apgar score was 6 in 1 minute and 8 in 5 minute. Although the infant needed intensive care for 90 days in the nursery room finally discharged in good condition. We report a case of twin pregnancy in which anencephaly was associated with a normal fetus, so after close counseling we opted to continue the pregnancy resulting in the delivery of a viable fetus.

Ancient bones have undergone natural decomposition and have been exposed to external environment for long period. Ancient DNA from old bone is usually fragmented. In addition, various kinds of inhibitors are co-extracted. All these may inhibit proper sequencing reaction. Cloning is regarded as the standard method when sequencing aDNA. When cloning, each clone from the same sample may not be of same sequence, and to exact consensus sequence may be difficult. Here we present our experience on 1200 year old bone from Russia, Primorsky Kray area. We have tried to sequence for HV I, II region of mtDNA using modified mini-primer set, which consisted of 7 set to cover the HV I, II. We cloned the PCR product and sequenced all the clones. Amplification efficiency and subsequent success rates were different for each mini primer set. Loci of variation that differ from consensus sequences were rather frequent, and the pattern were variable depending on sample. Except major polymorphic sites that are important when haplogroup designation, 16129 was the most frequent site that was discarded when extracting haplogroup designation.

Trisomy 18 is the second most common chromosomal anomaly that reach to live birth after Down syndrome. Several methods were proposed to screen patients on the risk of Edward syndrome like maternal serum levels using total human chorionic gonadotropin (hCG), alpha-fetoprotein (AFP) and unconjugated estriol (uE3), or free beta hCG with AFP, but the serum screening has only 50-60% detection rate with a 1-2% of false positive rate. So to cover the limitations that serum marker has, detailed ultrasound examination is also necessary and sensitivities of 65-70% were reported. We report a case of trisomy 18 fetus in which second trimester triple markers of maternal serum was normal, but by detailed ultrasound examination, unilateral radius aplasia was diagnosed cytogenetic study confirmed the fetus as trisomy 18.
