Purpose: To investigate trends in blood pressure (BP) and hypertension prevalence in Korea. Materials and Methods: Based on the Korean National Health and Nutrition Examination Survey (KNHANES) I (1998), II (2001),III (2005), IV (2007−2009), V (2010−2012), and VI (2013−2014), 56077 participants (23974 men and 32103 women) were included. Results: Mean systolic BP (SBP) and diastolic BP (DBP) decreased in both sexes (male SBP: 128.1 to 120.2 mm Hg, male DBP:82.0 to 78.5 mm Hg; female SBP: 125.7 to 116.0 mm Hg and female DBP: 77.4 to 73.2 mm Hg from the KNHANES I–VI). The agestandardizedprevalence of hypertension was significantly decreased in both sexes (male; 33.3% to 30.3%, female; 28.7% to 22.7%,all p for trend <0.001). Regardless of taking anti-hypertensive medication or not, SBP and DBP declined universally in both sexes. Compared to the KNHANES I, the odds ratios (95% confidence intervals) of the KNHANES II to VI for less-than-normotensiveand less-than-hypertensive BP increased in both sexes. Conclusion: Mean BP levels in both sexes and hypertension prevalence showed downward trends during the 16-year period.

Joinning of Al_(2)O_(3) to STS316 has been carried out using Ag-Cu braze alloy system at temperature of 850 and 950℃ under vacuum. Ag-Cu eutectic alloy did not react with Al_(2)O_(3) at 850℃ and no wetting or chemical bonding occurred. However, active Ag-Cu filler metal with addition of Ti reacted with Al_(2)O_(3) chemically and resulted in wetting and chemical bonding. When Ag-Cu-Ti filler was used, reaction layers were formed at Al_(2)O_(3)/braze and braze/STS316 interface, and metallic elements of STS316 such as Fe, Ni and Cr were diffused into braze. The presence of indium in Ag-Cu alloy limited the transfer and diffusion of the metallic alloy elements into braze. Using the Ag-Cu alloy with addition of Ti, a sound braze joint has been obtained.

The purpose of this study was make an observation on effects of anthelmintics such as Albendazole, Ivomec-F and Nilzan for amount of milk production and milk fat levels before and after administration on Nematoda, Trematoda and Cestoda in helminths infestated from 218 heads of dairy cattle in Gyongi province. The results are summerizied as follows : Infestation and distribution rate in percent of helminths among the collected fecal samples from dairy cattle are Bunostomum species(spp.) 1.3%, Strongyloides spp. 4.5%, Tricostrongylus spp. 0.8%, Ostertagia spp. 7.3%, Cooperia spp. 4.7%, Nematodrius spp. 1.6%, Haemonchus spp. 5.7% and Oesphagostumum spp. 6.5% in Nematoda, and that of Eurytrema app. 2.1%, Fascioloa spp. 11.8% and Pharamphistomum spp. 51.3% in Trematoda, and that of Moniezia spp. in Cestoda, respectively. After administration for three kinds of anthelminthics infestated dairy cattle, high level of efficacy were confirmed against Nematodes and Cestodes. The average values tend to be incresed amount of milk production and its fat levels after anthelmintics administration on helminths infestated dairy cattle were 1.8 kg and 0.14 % per daily, respectively (p<0.01). Key word : Infestation of helminths in dairy cattle, Effects of milk products.

The body weight and hemogram of mice that were inoculated the Serratia marcescens into the teat canals and caudal veins was investigated. The results obtained were as follows : 1.Significant difference was shown in the treatment groups in body weight of mice infected the Serratia marcescens into teat canals, but it was not shown in times. 2.The leucocytes of the mice were decreased remarkably in 24 hours, but the erythrocytes, the hemoglobin volume, the hematocrit value, the mean corpuscular hemoglobin, the mean corpuscular volume and the mean corpuscular hemoglobin concentration were not significant difference in mice infected the Serratia marcescens into teat canals and caudal veins.
인슐린 비의존형 당뇨병 환자에서 만성합병증과 혈청 sialic acid농도

Background: An elevated serum sialic acid concentration has recently been shown to be a potent predictor of cardiovascular mortality in the general white population. Microalbuminuria has been shown to be a independent risk factor or predictor of diabetic nephropathy and macroangiopathy in NIDDM. Several studies have shown a elevated serum sialic acid concentrations in NIDDM patients compared with nondiabetic subjects and in IDDM patients with microalbuminuria and clinical proteinuria. Methods : We studied 29 patients with NIDDM who had a normal urinary albumin excretion rate, 16 patients who had microalbuminuria, and 23 patients with clinical proteinuria. We also investigated sialic acid levels related to blood pressure, microalbuminuna, glycemic control, lipid analysis, serum sialic acid levels, and retinopathy. Results : 1) This study shows that NIDDM patients with macroalbuminuna had significantly higher serum sialic acid concentrations than control group, normoalbummuria, and microalbuminuria group.(meand:SE : 90.41±5.6 vs. 69.7±3.8, 68.2±2.4 and 72.6±2.9mg/dl, p<0.05 respectively). 2) Multiple linear regression analysis showed that systolic blood pressure, duration of diabetes, diastolic blood pressure, triglyceride, ESR, and albumin excretion rate (AER) correlate independently with logarithmic serum sialic acid concentrations. 3) The presence or absence of diabetic retinopathy had no impact on serum sialic acid concentration. Conclusions : This study shows that the serum sialic acid concentration is raised in NIDDM patients with macroalbuminuria. And there are no relationships between serum sialic acid and diabetic retinopathy. Further study is needed to confirm the mechanism of elevated serum sialic acid in NIDDM. And prospective studies are thought to be required to evaluate whether serum sialic acid concentration can be used as a predictor of microvascular and macrovascular complications in diabetes.

The polymerase chain reaction(PCR) amplification were performed with two synthetic oligonucleotide PCR primer(IS900 and PM103) and bacterial DNA templete. The PCR test were used for detection and identification of Mycobacterium paratuberculosis and it's test had a sensitivity greater than that obtained by standard culture technique and was much more rapid in Diagnosis of Johne's disease in cattle.
