본 연구는 논에서 조사료 생산을 위한 작부형태별 우분액비의 시용효과를 규명하기 위하여 총체 벼 재배 후 우분액비 시용에 따른 총체보리 및 IRG의 생산성, 사료가치, 토양성분 및 용탈수중의 무기물 농도를 조사하였다. 본 연구는 2006년 5월부터 2009년 4월까지 3년 동안 전라북도 김제군 백산면 시험포장에서 완전임의배치 3반복으로 수행되었다. 총체보리의 2년간 평균수량은 7,520 kg/ha, 그리고 IRG는 평균 10,320 kg/ha으로 IRG가 총체보리 보다 현저하게 높은 수량을 보였다 (p<0.05). 이탈리안 라이그라스는 1번초가 2번초 보다 약 2배 이상의 수량을 보였다. IRG의 조단백질 함량은 총체보리보다 높았고 NDF, ADF 및 TDN 함량은 작물간에 큰 차이는 보이지 않았다. 경작형태별 우분액비 시용에 따른 토양내 pH, $P_2O_5$, T-N, OM 농도는 시험전에 비해 시험종료 후에 현저하게 증가하는 경향을 나타냈다 (p<0.05). 경작형태별 우분액비 시용에 따른 토양내 Ca, Na, Mg 및 K 농도는 시험전에 비해 시험종료 후에 현저하게 증가하는 경향을 나타냈다 (P<0.05). 경작형태별 우분액비 시용에 따른 용탈수중 $NH_4$-N, $NO_3$-N, $PO_4$-P, Cl, Ca, K, Mg, Na의 농도는 경작형태에 따른 확실한 차이를 보여주지 않았다. 따라서 논에서 우분액비를 이용하여 동계작물을 재배할 경우에는 수량도 중요하지만 환경적인 부분도 고려하여 우분액비를 이용해야 한다. This study was conducted to investigate the effects of cattle slurry on productivity of whole crop barley and Italian ryegrass and environmental pollution in paddy land. Cropping systems used in this study were consisted of two designs, such as whole crop barley applied with cattle slurry (WCB) and Italian ryegrass applied with cattle slurry (IRG). The field experiments were conducted on the clay loam at Backsanmyun, Kimje, Chunlabukdo province in Korea for three years (May 2006 to Apr. 2009). This study was arranged in completely randomized design with three replicates. The yields of WCB and IRG were 7,520 kg/ha and 10,320 kg/ha, respectively. The yields of IRG significantly increased as compared with that of WCB (p<0.05). The yield of Italian ryegrass in 1st cutting time was about 2-fold higher than that of 2nd cutting time. The contents of crude protein of IRG were higher than that of WCB. However, the contents of NDF, ADF and TDN were no difference between WCB and IRG treatments. The pH, and contents of T-N, $P_2O_5$ and organic matter (OM) in soil samples collected at the end of the experiment increased as compared with those at the beginning of the experiment (p<0.05). After the end of experiment, the concentrations of CEC (Ca, Na, Mg and K) in soil samples collected at the end of the experiment were remarkably higher than those at the beginning of the experiment (p<0.05). The concentrations of $NH_4$-N, $NO_3$-N, $PO_4$-P, Cl, Ca, K, Mg and Na in leaching water in paddy land cultivated with WCB and IRG were no difference between WCB and IRG treatments.

A Bicon Frise (7-month-old, intact female, B.W.: 3.5kg) was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of the murmur which was picked up during routine vaccination. The grade 3 of continuous murmur was identified on the auscultation. In the thoracic radiography, descending aorta and main pulmonary artery were enlarged and vertebral cardiac scale (VHS) was 10. In the echocardiography, turbulent and continuous positive flow was identified in the pulmonary artery at the right parasternal short axis view. We found the patent ductus arteriosus (PDA) connected the main pulmonary artery with the aorta by CT image. So, the diagnosis of PDA was made. The continuous murmur was not identified on the auscultation after surgical correction was achieved by ligation of PDA.

In order to investigate to develop the new dosage form of the traditional herbal medicine which have been used for the treatment of disease in oriental medicine, we conducted a survey on 217 patients who visited oriental hospital in Kyung Hee University Medical Centre during one month since October 2003. They were given questionnaires to answer and results of this study were as the following: 1. About 45% patients visited in oriental hospital believed that oriental medicine was better remedy than modern medicine. 2. Most of patients felt that the oriental medical expenses were expensive. 3. About 60% patients preferred the modernized dosage form such as extract powder and granule, etc. rather than medicinal herbs in package. 4. Most of patients hope that decoction of medicinal herbs in package would change the advanced dosage forms such as tablet, capsule and extract powder, Because patients suffered from inconvenience of making a decoction, unhandy, unwieldy and keeping. 5. About 60% patients pointed out that merits of advanced dosage forms of medicinal herbs were convience to take and handy, etc.. However, they had an Intension that there were some difference of efficacy between decoction and modernized dosage forms of oriental medicine. Because of several defects such as unusual flavor and smell, incompatible food, large volume with amount, inconvenience of carrying and decocting oriental herbal medicines, most of patients would expect the development of the advanced dosage forms of them. In summary, this study show that it was needed to develop the new dosage forms of oriental herbal medicine on the basis of scientific research and economical cost of medical expenses.

This study was attempted to investigate the pharmacokinetics of theophylline in rabbits with folate induced renal failure. Plasma concentration and AUC of theopylline were increased in rabbits with folate induced renal failure compared with those of normal rabbits. Renal clearance and total body clearance were decreased in rabbits with folate induced renal failure compared with those of normal rabbits. Correlation of serum creatinine concentration and AUC, and correlation of serum creatinine clearance and renal clearance have linear relationship respectively. From the results of this experiment, it is desirable that dosage regimen of theophylline should be adjusted for effective and safe therapy in patient with renal failure in clinical pharmacy practice.

During the last several decades, although there have been lots of efforts to develope the high-frequency bottom reflection loss model, the frequency dependence of bottom loss was not considered in most cases because the sea bottom was assumed to be generally much smoother and lower gradient than the sea surface. However, if the sea bottom is rougher than acoustic wavelength, the scattered field will be increased and the reflected field will be decreased. In this paper, the high-frequency bottom reflection losses were obtained through the measurement of reflected waves from the artificially-made-flat sandy bottom. The experimental data were compared with the values calculated by the forward loss model of Mourad & Jackson. Conseouently, we suggest the frequency dependence of bottom reflection loss. 기존 해저면 반사손실 모델들은 해저면을 해수면에 비해 거칠기와 경사도가 매우 평탄하거나 완만한 경계면으로 가정하므로 주파수에 따른변화를 고려하지 않거나 미약하다고 가정하였다. 그러나 고주파를 사용하는 소오나 시스템의 경우, 음파의 파장에 비해 해저면이 거칠다면 음파는 산란 영향이 증가하게 되므로 상대적으로 반사손실 또한 증가하게 된다. 따라서 본 논문에서는 임의로 모의된 사질 성분의 해저면에서 수십 ㎑ 이상의 고주파들을 사용하여 주파수별 반사손실을 계산하고, 이를 기존의 해저면 반사손실 모델과 비교하였으며, 해저면 반사손실의 주파수 종속성을 제시하고자 한다.

Purpose: Hyponatremia occurs infrequently in patients undergoing peritoneal dialysis (PD). Nevertheless, one must understand its pathophysiology, since the therapeutic strategy differs from that of non-PD-related hyponatremia. This study examined the clinical features of hyponatremia in PD and evaluated the factors that may contribute to its development. Methods: We retrospectively enrolled 51 normonatremic PD patients at Gachon University Gil Hospital, South Korea. Using the plasma sodium levels at month 13, the patients were divided into hyponatremia (Na+<135mEq/L) and normonatremia (Na+≥135mEq/L) groups. Then, the clinical variables of these patients were examined, including peritoneal function and adequacy tests, and biochemical parameters. Results: The de novo hyponatremia (n=8) and normonatremia (n=43) groups had no significant differences in baseline characteristics. At month 1, the serum albumin was lower in the hyponatremia group (p=0.022). In the peritoneal equilibration test analysis, the dialysate-to-plasma ratio for creatinine (D/Pcr) measured after 13 months differed significantly between the two groups (p=0.007), while the maximum dip in sodium did not differ. No significant differences were observed in the normalized protein equivalent of nitrogen appearance, Kt/V, or residual renal function. Conclusion: Our data suggest that the development of hyponatremia is associated with a lower initial serum albumin level and increased D/Pcr in patients undergoing PD. Therefore, the serum sodium levels should be monitored more carefully in these patients.

SLE 환자에서 간 효소 수치의 상승은 여러 가지 원인에 의하여 드물지 않게 관찰될 수 있다. 이 중 자가 면역 기전에 의해 발생되는 질환으로 자가 면역성 간염과 SLE에 동반된 간염이 있으며, 두 가지 질환의 감별은 환자의 예후 및 치료에 중요하다. 따라서 간 조직 검사를 포함한 정확한 진단 기준으로 조기에 진단하여야 하며, 이에 따른 적절한 치료를 통해서 간 부전 및 비가역적 간경변증으로 진행을 방지할 수 있을 것으로 사료된다. Patients with systemic lupus erythematosus (SLE) have a 25-50% chance of developing abnormal liver tests in their lifetime and various causes are related to elevation of liver enzyme, such as hepatic involvement of lupus, hepatotoxic drug, viral infection, autoimmune hepatitis and so on. Discrimination of autoimmune hepatitis from SLE-associated hepatitis is important because complications and therapy are quite different, although both are autoimmune syndromes. Here we are presenting a case of SLE patient with type I autoimmune hepatitis proved with liver biopsy.

Effect of the Ethanol Extract of Propolis on Formation of Streptococcus mutans Biofilm

Bog-Im Park,Yeon-Woo Jung,Young-Hoi Kim,Sang-Moo Lee,Lee-Seong Kwon,Kang-Ju Kim,So-Youn An,Na-Young Choi6,Yong-Ouk You 대한구강생물학회 2016 International Journal of Oral Biology Vol.41 No.4

Streptococcus mutans (S. mutans) is one of the most important bacteria in the formation of dental plaque and dental caries. S. mutans adheres to an acquired pellicle formed on the tooth surface, and aggregates with many oral bacteria. It initiates plaque formation by synthesizing glucan from sucrose, which is catalyzed by glucosyltransferases. Propolis is a resinous mixture produced by honeybees, by mixing saliva and beeswax with secretions gathered from wood sap and flower pollen. Bees prevent pathogenic invasions by coating the propolis to the outer and inner surface of the honeycomb. Propolis has traditionally been used for the treatment of allergic rhinitis, asthma and dermatitis. We investigated the inhibitory effects of propolis ethanol extract on biofilm formation and gene expression of S. mutans. The biofilm formation of S. mutans was determined by scanning electron microscopy (SEM) and safranin staining. We observed that the extract of propolis had an inhibitory effect on the formation of S. mutans biofilms at concentrations higher than 0.2 mg/ml. Real-time PCR analysis showed that the gene expression of biofilm formation, such as gbpB, spaP, brpA, relA and vicR of S. mutans, was significantly decreased in a dose dependent manner. The ethanol extract of propolis showed concentration dependent growth inhibition of S. mutans, and significant inhibition of acid production at concentrations of 0.025, 0.05, 0.1 and 0.2 mg/ml, compared to the control group. These results suggest that the ethanol extract of propolis inhibits gene expression related to biofilm formation in S. mutans.
