N/A Most authorities agree the higher incidence of gallstones among diabetic patient. Although many reports on gallstones or diabetes mellitus have been published, and actual correlation between gallstones and diabetes mellitus remains obscure. The purpose of this reports is to know the incidence of gallstone in diabetics and of diabetics in the patients with gallstone. Authors studied prospectively and clinically the diabetics in a group of 173 patients with gallstones and gallstone in a group of 98 diabetic patients who were admitted to Yonsei University Yong-Dong Hospital for the same period of April 1983 to May 1984. The results obtained are summarized as follow: The incidence of gallstone to general admission patients is 1.5% and the prevalence of diabetes mellitus to total in-patients is 0.8% The gallstone was found in 11.0% of diabetics and were diabetic 19.4% of patients with gallstones. The age of peak incidence of gallstones is 5th decade and female was more prevalent than male with the ratio of 1.37:1. The age of peak incidence of diabetes mellitus is 6 th decade and female is less prevalent with the ratio of 0.72:l.3, The most common characteristic finding of patients of gallstones with diabetes mellitus is symptomless(42.1%)4, There is no significant difference in serum levels of cholesterol and triglyceride between diabetic and non-diabetic groups or with and without gallstones. 5. Comparative study on location of stones revealed, 72.8% in gallbladder only, 12.7% in common bile duct only, 4. 6% in intrahepatic duct only, and remainders in multiple site. There is no significant difference in terms of location of stone between diabetic and nondiabetic group.

This work was accomplished with 6 day-old rye (Secale cereale L.) seedlings to determine the effect of the antibiotics by cycloheximide on in vivo nitrate reductase activity, protein and RNA content. The nitrate reductase activity by treating 0.1μM and 0.1 mM cycloheximide was lower than that of the control group. The optimum pH for the nitrate reductase of the control group was 7.6 in the range of pH 5.6-8.0, but, in the case of 0.1mM cycloheximide treatment group, the optimum pH was decreased to 6.8 within the weak the acid region. The protein content of shoot and root in the 0.1μM and 0.1 mM cycloheximide treatment groups were respectively found at the 96%, 82% level of that in the control group. In the higher cycloheximide treatment (0.1 mM CH), not only nitrate reductase activity and protein content but also RNA content was greatly decreased. In this fact, it was suggested that the 0.1 mM cycloheximide had affected on the RNA polymerase. On the basis of there results, it was concluded that the decreased nitrate reductase activity by treating cycloheximide occurred primarily according to the decreased nitrate uptake, and the decreased protein and RNA content depended upon the results of the direct and indirect effect of cycloheximide on the protein synthesis.

본 연구에서는 폴리머 복합체의 일종인 폴리머 콘크리트의 내후성과 가공성을 개선하기 위하여, 스티렌 모노머에 MMA를 혼합하여 물성변화에 대한 연구를 수행하였다. 프로필렌 글리콜, 무수 말레인산, 무수프탈산을 축합 중합하였으며, 수지에 대하여 40wt%의 스티렌 모노머를 첨가하였다. 스티렌 모노머를 포함한 불포화폴리에스테르 수지(UPR)에 대하여 MMA를 0-50wt%를 첨가하였다. MMA와 UPR과의 상용성을 증대시키기 위하여, UPR 수지의 말단에 아크릴기를 도입한 수지를 제조한 후 물성을 비교하여 보았다. 인장강도 시험용 시편을 제조하여 만능시험기로 인장 강도실험을 실시한 결과 MMA의 함량이 40-50%일 때 최고치를 나타내었다. 시료의 점탄성적 물성을 DTMA를 이용하여 측정하였으며, MMA의 함량이 증대됨에 따라 저장 탄성률E'이 증대됨을 알 수 있었다. 특히 아크릴기를 분자말단에 도입한 UP 수지의 경우 저장 탄성률E'이 크게 증대되었다. 따라서 아크릴기의 도입에 의해 UPR의 MMA와의 상용성이 크게 증대되고 또한 물성도 향상되었음을 알 수가 있었다. In this study structure and property relationship of the UP resins containing MMA in order to improve the weatherability and processability of the polymer concretes was surveyed. UP resins were synthesized by condensation polymerization of propylene glycol, maleic anhydride and phthalic anhydride. The polymerized resin was subsequently dissolved into styrene to make 40wt.% solution. 0~50wt.% of MMA to the resin was added. Tensile test specimens were prepared according to the ASTM. UP resins containing 40~50wt% MMA/resin shows best tensile stress. Dynamic mechanical properties measurements by DMTA show storage modulus E' increased with increase of MMA contents. Especially the UP resins containing acryl group in the chain show much improved modulus. This result indicates that the improved mechanical properties attribute from the compatibility between UP resin and monomers. The results of DMTA are coincident with those of tensile test.

라텍스로 처리한 초속경시멘트(RS-LMC)에 사용되는 라텍스의 안정성의 평가 및 안정성을 증대시키기 위한 연구를 수행하였다. 비이온계 및 음이온계 계면활성제를 사용한 라텍스 시제품에 대하여 전기전도도를 측정하는 방법을 이용하여 안정성을 평가하였다. 라텍스에 PEG를 첨가한 후 라텍스 용액의 안정성에 미치는 영향을 평가하였다. 라텍스의 침전제로 CaCl_2를 사용하였다. 음이온계 계면활성제를 포함한 라텍스는 CaCl_2를 첨가하면, 즉시 침전현상이 발생되나, PEG를 처리한 경우에는 침전현상이 매우 느리게 일어나서 안정화 효과가 있음을 확인하였다. 반면, 비이온계 계면활성제를 포함한 라텍스는 침전현상이 거의 발생되지 않아 이러한 라텍스가 RS-LMC에 적합함을 확인하였다. 비이온계 계면활성제를 포함한 라텍스라 할지라도 1년이상 장기간 보존하면 안정성이 저하됨을 전기전도도를 측정하는 방법을 통하여 확인하였다. 장기간 보존한 라텍스의 경우 라텍스 용액내에서 미생물이 다량 성장하였음을 확인하였으며, 이러한 라텍스 용액의 경우 안정성이 저하됨을 알았다. This study is aimed at evaluating and improving the stabilities of latex in order to apply for the rapid set latex modified concretes (RS-LMC). Stability of latex solutions was evaluated by measuring electric conductivity for the commercial latexes containing nonionic or anionic surfactants. Polyethylene glycol(PEG) as a stabilizer was added to the latex solutions with anionic surfactants. Since the latex treated with PEG showed small conductivity difference Δk between upper and lower part of the latex solutions, it can be seen that PEG can effectively stabilize latex solutions. The nonionic type latex is most adequate for the RS-LMC because no coagulation occurred. It was confirmed by the conductivity measurement that the nonionic type latex preserved more than one year was not stable against coagulating agent, CaCl_2. Large quantity of bio-materials that would be related with the reduction of latex stability were observed in the culture growth of the long-time preserved latex.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

The aim of this study is to identify the data traffic capacity of 3G mobile communication networks, especially of cdma2000-1X networks. Three-layered ON/OFF traffic model is used to describe the dynamics of data traffics and the process of data transmission such as packet scheduling. We construct a simulator fully incorporating packet handling process of cdma2000-1X data network as well as three-layered ON/OFF traffic model describing the behavior of source data traffics. To get influence of traffic parameters on performance measures, the extensive simulations were performed for several data sets which are obtained from real trace data or previous studies. The experimental results show that the engineered throughput satisfying QoS criteria is approximately 20% of total capacity. Finally, some proposals to improve the system capacity are followed.

Therapeutic Potential of <i>Dioscorea</i> Extract (DA-9801) in Comparison with Alpha Lipoic Acid on the Peripheral Nerves in Experimental Diabetes

Jin, Heung Yong,Kim, Sun Hee,Yu, Hea Min,Baek, Hong Sun,Park, Tae Sun Hindawi Publishing Corporation 2013 Journal of diabetes research Vol.2013 No.-

<P>DA-9801, a mixture of extracts from <I>Dioscorea japonica</I> Thunb. and <I>Dioscorea nipponica</I> Makino, was reported to have neurotrophic activity. Therefore, we investigated the therapeutic potential of DA-9801, in comparison with alpha lipoic acid (ALA), for peripheral nerves preservation in experimental diabetes. Experimental animals were divided into 4 groups, and each group was designated according to the type of treatment administered as follows: normal, DM, DM+DA-9801, and DM+ALA. After 16 weeks, response thresholds to tactile and thermal stimuli were higher in DM+DA-9801 group than in nontreated DM group. This degree of increase in DM+DA-9801 group indicates more therapeutic potency of DA-9801 than ALA. Western blot analysis showed more significant increase in NGF and decrease in TNF-<I>α</I> and IL-6 in DM+DA-9801 group than in DM or DM+ALA groups (<I>P</I> < 0.05). IENF density was reduced less significantly in the DM+DA-9801 group than in other DM groups (7.61 ± 0.32, 4.2 ± 0.26, and 6.5 ± 0.30 in DM+DA-9801, DM, and DM+ALA, resp., <I>P</I> < 0.05). Mean myelinated axonal area in the sciatic nerves was significantly greater in DM+DA-9801 group than in other DM groups (69.2 ± 5.76, 54.0 ± 6.32, and 63.1 ± 5.41 in DM+DA-9801, DM, and DM+ALA, resp., <I>P</I> < 0.05). Results of this study demonstrated potential therapeutic applications of DA-9801 for the treatment of diabetic peripheral neuropathy.</P>
