BACKGROUND AND OBJECTIVES: Systolic and diastolic blood pressure may have different effects on cardiovascular disease, but limited data is available for hypertension subtypes in the Korean population. Thus, the prevalence, and absolute number of hypertension subtypes among Korean adults was estimated. SUBJECTS AND METHODS: The Korea National Health and Nutrition Examination Survey 1998-2012 was used to estimate the prevalence and absolute number of each hypertension subtype among Korean adults aged > or =20 years. Hypertension was classified into four subtypes: treated hypertension (TH), isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and combined systolic and diastolic hypertension (SDH). RESULTS: In 2012, approximately 9.5 million adults were estimated to have hypertension, which consists of 5675671 TH (60.0%), 954253 ISH (10.1%), 1649486 IDH (17.4%), and 1175506 SDH (12.4%). Between 2010 and 2012, the proportion of IDH steadily decreased with age, but ISH increased especially in older ages (> or =40). Between 1998 and 2012, TH markedly increased from 1.4 million to 5.7 million while the number of untreated hypertension remained relatively constant. During the same time, the number of hypertensive elderlies increased from 507000 to 2822000 along with rapid ageing of the Korean population. Despite of significant improvement in treatment rate, there are still around 583000 elderlies with untreated hypertension (423000 ISH; 42000 IDH; 118000 SDH) as of 2012. CONCLUSION: Although the prevalence of hypertension has been constant over the last decades, absolute number of people with hypertension has been increasing. Along with the rapid population ageing, the number of elderly hypertension is increasing and the ISH is also becoming more prevalent.

PURPOSE: The purpose of this study was to assess the prevalence and radiographic characteristics of the nuchal ligament ossification on lateral cephalometric radiographs in Koreans. SUBJECTS AND METHOD: I review and interpreted the lateral cephalometric radiographs from 4,558 patients (1,857 males and 2,701 females, age range from 2 to 79 years) who visited the Kyungpook National University Dental Hospital from January 1, 2008 to February 3, 2009. I grouped the shapes of nuchal ligament ossification as round, rod-like, and segmented shape. And localized the ossification as the involvement of anterior cervical vertebral body. The data were analyzed by using chi-squared test with two-tailed and at a 5% significance level. RESULTS: Among those who showed the nuchal ligament ossification, the mean age of the 143 males was 51.1 and that of the 97 females was 48.0 years. It was not observed completely below teens, and was observed 1% in twenties, 6.1% in thirties, 18.6% in forties, and 26.3% over fifties. It was significantly prevalent in older age group (P<0.01) and in males than females among the same age group (P<0.05). The shapes of nuchal ligament ossification were as follows in order of frequency : rod-like (49.2%), round (30.4%), and segmented (20.4%). The highest involvement of ossification was found at the level of C5 (67.9%), C4 (29.2%), C6 (22.9%), C3 (3.3%), C7 (2.9%), C2 (0.8%), and C1 (0.4%). CONCLUSION: The nuchal ligament ossifications on lateral cephalometric radiographs were showed as round, rodlike, or segmented shape. The nuchal ligament ossification is often observed after the age of 40 and is observed more frequently in males than females. The highest shape of nuchal ligament ossification was rod-like shape and the highest involvement of cervical spine was C5.

OBJECTIVES: The purposes of this clinical study were 1) to assess 5-year survival rates in 195 patients with locally invasive cervical cancer(stage Ia-IIb) treated by surgery, neoadjuvant chemotherapy+surgery and postoperative radiation in selected cases, 2) to evaluate the prognostic factors affecting the survival rate, and 3) to get helpful information for the better treatment. METHODS: A retrospective analysis was conducted of 195 patients. They were diagnosed and operated on during the period of Jan. 1988 - Dec. 1993 in Dept. of OB/Gyn, Pusan Paik Hospital, Inje Medical School. The 5-year survival rates were estimated using the Kaplan-Meier method, and prognostic factors were assessed using Wilcoxon test. RESULTS: The 5-year survival rates for FIGO stages Ia, Ib, IIa, and IIb were 100, 86.1, 76.9, and 81.1%, respectively. Factors that affect the 5-year survival rates were clinical stage(P=0.0001), cell type(small cell vs other, P=0.0001), depth of invasion(< or = 5 mm vs >5 mm, P=0.0013), tumor size(< or = 3 cm vs >3cm, P=0.0035), and lymph node metastasis(0 vs 1 vs more than 2, P=0.0001). There was no difference in 5-year survival rates between without neoadjuvant chemotherapy group and with neoadjuvant chemotherapy group which had poor prognostic factors. The predicted recurrence rate of the postoperative radiation group showed a lower 5-year survival rate than the no postoperative radiation group(P=0.0001). CONCLUSIONS: We conclude that the factors affecting the prognosis were FIGO stage, cell type, depth of invasion, tumor size, and lymph node metastasis, and speculated that the survival rates could be improved by using neoadjuvant chemotherapy for more advanced locally invasive cases properly.

Cardiovascular disease is the leading cause of death worldwide and the second most common cause of death in Korea. Dyslipidemia is among the major modifiable risk factors for cardiovascular disease. To develop effective guidelines for the management of dyslipidemia, it is important to understand the epidemiologic characteristics of dyslipidemia in the target population. The prevalence of dyslipidemia in the Korean population has been reported variously from 30% to higher than 60%, but, in general, the prevalence of dyslipidemia among Koreans has been increasing. Among the subtypes of dyslipidemia, hypercholesterolemia and hyper-LDL cholesterolemia are relatively uncommon in Korea compared to other high-income countries. On the other hand, hypertriglyceridemia and hypo-HDL cholesterolemia are very common in Korea. Recent data shows that total and LDL cholesterol levels are increasing in the Korean population, while triglyceride and HDL cholesterol levels have not been changing. As a consequence, the prevalence of hypercholesterolemia and hyper-LDL cholesterolemia is increasing. These data reinforce the need to make a greater effort toward the prevention and treatment of dyslipidemia.

PCR implication using the primers for gag, pol and rev genes in BLV (bovine leukemia virus) proviral DNA and syncytium assay were carried out for the Korean native goats experimentally infected with bovine leukemia virus to investigate pathogenesis of BLV in the goats, and to establish a model animal for BLV infection. The oligonucleotide primers used in PCR revealed very high specificity, The minimal amount of FLK-BLV cellular chromosomal DNA to detect the integrated BLV proviral DNA was 10 ng. The peripheral blood lymphocytes from the goat infected with BLV were examined at regular intervals by PCR amplification and syncytium assay. Pol or gag genes were detected in none of three infected goats at the 1st week post-infection (p.i.). At the 4th week p.i., one of three goats showed the amplified gag gene. Thereafter detection rates for the genes were increased, indicating that the BLV proviral genes were integrated in all of the lymphocytes from three goats, at the 16th weeks p.i., when it was evident in syncytium assay that the lymphocytes from all of three goats were infested with infective BLV. Investigating the tissues from the necropsied goats at the 8th month p.i., the amplified BLV proviral genes and infective BLV were detected in all of the peripheral lymphocytes from three infected-goats. Among various tissues examined, the amplified BLV proviral genes were observed in spleen and superficial cervical, mandibular and retropharyngeal lymph nodes, and the infective BLV, in superficial cervical and mandibular lymph nodes. It was assumed that the Korean native goat was quite susceptible to BLV infection, indicating that the goat could be a good model animal for BLV.
