  • Background and objective : Rabeprazole is a new generation proton pump inhibitor, which has a rapid onset after first dose, predictable efficacy in all patients regardless of CYP2C19 genotype status, and less nocturnal acid breakthrough. The aim of the study is to investigate clinical efficacy and safety of rabeprazole sodium (Pariet 10mg qd)when administered once daily to patients with laryngopharyngeal reflux(LPR) disease. Methods : Among the patients who had visited the Department of Otolaryngology, those with LPR symptoms, had undergone laryngoscopy. Symptoms and endoscopic laryngeal sings were recorded initially, at 1 month, 2 months, 3 months, and more than 3 months, All patients were evaluated for clinical efficacy on the basis of symptom scores, reflux finding score(RFS), and side effects. Results : In general, most symptom scores and RFS improved over the time. Efficacy of the Pariet on LPR-related symptoms were $63.2\%,\;77.5\%,\;78.7\%,\;and\;90.9\%$ before 4 weeks, 4 to 8 weeks, 8 to 12 weeks, and after 12 weeks respectively. Efficacy on the RFS were $61.8\%,\;78.4\%,\;82.9\%,\;and\;85.5\%$ before 4 weeks, 4 to 8 weeks, 8 to 12 weeks, and after 12 weeks respectively. Pariet was well tolerated and was associated with few drug-related side effects. Conclusion Because of its efficacy and safety, Pariet may prove to be an alternative to currently available proton pump inhibitors.

  • 피조개 양식장으로 이용되고 있는 남해 연안의 진주만에서 저서 다모류 분포를 밝히기 위하여 van Veen grab 채니기를 이용하여 1999년 8월부터 2000년 5월 사이에 계절별로 4회에 걸쳐 저서동물을 채집하였다. 조사기간 중 총 132종의 저서 다모류가 채집되어, 출현한 전체 저서동물 개체수 중 약 $80\%$를 차지하였다. 다모류의 평균 출현 개체수는 계절별로 뚜렷한 차이를 나타내지 않았으나 생체량은 여름 (8월)에 가장 높았던 반면, 종 다양도와 풍도는 여름철에 가장 낮았다. 이것은 계절에 따른 종조성 변동에 의한 다모류 군집 차이를 반영하는 것으로, 이와 같은 계절변동은 봄철에 소형의 몇몇 r-선택성 기회종과 여름철에 서관을 만드는 Mal-danidae과 종의 출현에 기인하였다. 한편, Capitella Capitata, No-tomastus latericeus 및 Lumbrineris sp.와 같이 유기물이 풍부한 해역에서 흔히 출현하는 종들이 만 전체적으로 연중 높은 밀도를 나타내었다. 남부의 피조개 양식장 수역은 상대적으로 낮은 개체수와 생체량을 나타내었는데, 종 다양도와 풍도 역시 상대적으로 낮은 경향을 보였다. 주성분 분석의 결과는 만내 다른 수역에서 우점하는 Maldanidae과는 물론 소형 기회종의 출현 빈도가 피조개 양식장 수역에서 대단히 낮아 피조개 양식장 수역 저서 다모류 군집이 인근 나머지 정점군들의 군집과 뚜렷이 구분된다는 것을 잘 보여주었다. 다모류 군집의 공간변동은 피조개 양식장 수역 퇴적물의 더욱 세립한 입도 조성과 높은 황화물 농도 및 북부 일부 정점의 낮은 염분 등에 의해서 부분적으로 설명될 수 있었지만, 다른 환경 변수에서 이와 같은 차이는 뚜렷하지 않았다. 진주만에서 다모류 군집의 공간분포는 오히려 봄철에 피조개 채취를 위한 퇴적물의 물리적 교란에 의해 크게 영향을 받는 듯 하였다. 않고 사육조 수면으로 공급되는 우회량이 많을 경우 용존산소는 증가하였으나 수처리 장치로 공급되는 유량이 작아 부유 고형물, 유기물 등의 수질 인자가 악화되는 현상을 보였다.대된다.. 창란젓갈 저장시 품질측정변수에 대한 상관관계를 조사한 결과병포장에서는 용기내 압력, pH, L값, VBN, 관능검사 등이 상관관계가 높아 젓갈 포장에서 품질지표항목으로 이용할 수 있을 것으로 기대된다.는 0.1 mM과 0.4 mM 및 0.8 mM 배양구는 배양 5시간 후에 최대값이 되어 각각 $204\%$, $198\%$$191\%$로 증가하였다. 이처럼 BNF나 PB, MC는 명주조개에서도 미크로좀의 CYP 함량과 EROD 활성을 증가시키는 유도효과를 나타내었으며, 특히 MC에 의한 유도효과가 가장 강했고 BNF, PB의 순이었고, 대체로 약물의 농도가 높을수록 유도 효과도 큰 경향을 보였다.이 한국어와는 다른 것이라거나, 한국어 음성학을 공부하지 않고 한국어를 연구할 수 있다는 뜻은 아닙니다. 의학에도 분야마다 전문의가 있듯이, 언어학도 이제 복잡하고 광범한 학문이 되었으므로 분야별로 전문가가 나오게 된 것뿐입니다. 따라서 "나는 통사론에 관심이 있으므로 소리말에는 관심이 없다"고 말하는 언어학자가 있다면, 이 것은 크게 잘못된 것입니다. 마찬가지로 "나는 소리에만 관심이 있으므로 통사론에는 관심이 없다"고 말하는 음성학자가 있다면, 이 또한 안되는 일입니다. 문의 구성과 어휘 요소와 아무 관련이 없는 말소리의 차이가 무슨 소용이 있으며, 통사 구조를 표현하고 저달하는 말소리를 연구하지 않고 어떻게 통사론을 연구할 수 있겠습니까? 다시 간추리면, 언어는 본질적으로 소리말이고, 언어의 특성과 사용 및 습득도 모두 소리말 형태로 나타납니다. 따라서, 영국의 대학은 음성학이 대단히 중요함을 인식하고, 언어학을 올바르게

  • 본 연구는 떫은감 청도반시의 분말을 열수 추출하고 칼럼 추출하는 과정에서 획득한 PWE와 TEP에 대한 대사체 프로파일을 분석하고, 유리지방산을 처리한 HepG2 세포와 식이로 고지혈증을 유도한 Wistar계 흰쥐의 간조직을 사용하여 중성지질 및 콜레스테롤 대사 관련 유전자 발현을 측정하였다. 대사체 분석은 가스크로마토그래프-질량분석법과 액체크로마토그래프-질량분석법을 사용하였으며, PLS-DA 분석과 heatmap 분석을 실시한 결과 PWE는 떫은감 분말과 비교적 유사한 대사체 프로파일을, 그리고 TEP는 떫은감 분말과 매우 다른 대사체 프로파일을 가지고 있음을 확인하였다. 세포실험과 또한 세포실험에서 얻어진 결과를 검증하기 위해 수행된 동물실험에서 PWE와 TEP는 모두 SREBP1c와 FAS 유전자 발현을 감소하여 간의 지방축적을 감소시키는 것으로 관찰되었으나, 콜레스테롤 축적을 억제하는 효능은 PWE에 비해 TEP에서 우세하게 증가하는 것이 관찰되었다. 특별히 TEP는 SREBP2, HMGCR 유전자 발현을 억제하고 LDLR 유전자 발현을 촉진하는 것으로 나타났다. TEP는 탄닌 중 Gallic acid 그리고 장쇄지방산아미드인 Oleamide와 Palmitamide 함량이 유의하게 증가되었으므로, 향후 이들 성분과 타깃 유전자의 상관성을 분석하고, 이를 통해 시스템네트워크로 나타내어 대사체 프로파일에 따른 지질 및 콜레스테롤 대사 간 상호 영향을 추가적으로 연구해야 할 것으로 사료된다.

  • The success of the family planning program in Korea is reflected in the decrease in the growth rate from 3.0% in 1962 to 2.0% in 1971, and in the decrease in the fertility rate from 43/1,000 in 1960 to 29/1,000 in 1970. However, it would be erroneous to attribute these reductions entirely to the family planning program. Other socio-economic factors, such as the increasing age at marriage and the increasing use of induced abortions, definitely had an impact on the lowered growth and fertility rate. Despite the relative success of the program to data in meeting its goals, there is no room for complacency. Meeting the goal of a further reduction in the population growth rate to 1.3% by 1981 is a much more difficult task than any one faced in the past. Not only must fertility be lowered further, but the size of the target population itself will expand tremendously in the late seventies; due to the post-war baby boom of the 1950's reaching reproductive ages. Furthermore, it is doubtful that the age at marriage will continue to rise as in the past or that the incidence of induced abortion will continue to increase. Consequently, future reductions in fertility will be more dependent on the performance of the national family planning program, with less assistance from these non-program factors. This paper will describe various approaches to help to the solution of these current problems. 1. PRACTICE RATE IN FAMILY PLANNING In 1973, the attitude (approval) and knowledge rates were quite high; 94% and 98% respectively. But a large gap exists between that and the actual practice rate, which is only 3695. Two factors must be considered in attempting to close the KAP-gap. The first is to change social norms, which still favor a larger family, increasing the practice rate cannot be done very quickly. The second point to consider is that the family planning program has not yet reached all the eligible women. A 1973 study determineded that a large portion, 3096 in fact, of all eligible women do not want more children, but are not practicing family planning. Thus, future efforts to help close the KAP-gap must focus attention and services on this important large group of potential acceptors. 2. CONTINUATION RATES Dissatisfaction with the loop and pill has resulted in high discontinuation rates. For example, a 1973 survey revealed that within the first six months initial loop acceptance. nearly 50% were dropouts, and that within the first four months of inital pill acceptance. nearly 50% were dropouts. These discontinuation rates have risen over the past few years. The high rate of discontinuance obviously decreases the contraceptive effectiveness. and has resulted in many unwanted births which is directly related to the increase of induced abortions. In the future, the family planning program must emphasize the improved quality of initial and follow-up services. rather than more quantity, in order to insure higher continuation rates and thus more effective contraceptive protection. 3. INDUCED ABORTION As noted earlier. the use of induced abortions has been increase yearly. For example, in 1960, the average number of abortions was 0.6 abortions per women in the 15-44 age range. By 1970. that had increased to 2 abortions per women. In 1966. 13% of all women between 15-44 had experienced at least one abortion. By 1971, that figure jumped to 28%. In 1973 alone, the total number of abortions was 400,000. Besides the ever incre.sing number of induced abortions, another change has that those who use abortions have shifted since 1965 to include- not. only the middle class, but also rural and low-income women. In the future. in response to the demand for abortion services among rural and low-income w~men, the government must provide and support abortion services for these women as a part of the national family planning program. 4. TARGET SYSTIi:M Since 1962, the nationwide target system has been used to set a target for each method, and the target number of acceptors is then apportioned out to various sub-areas according to the number of eligible couples in each area. Because these targets are set without consideration for demographic factors, particular tastes, prejudices, and previous patterns of acceptance in the area, a high discontinuation rate for all methods and a high wastage rate for the oral pill and condom results. In the future. to alleviate these problems of the methodbased target system. an alternative. such as the weighted-credit system, should be adopted on a nation wide basis. In this system. each contraceptive method is. assigned a specific number of points based upon the couple-years of protection (CYP) provided by the method. and no specific targets for each method are given. 5. INCREASE OF STERILIZA.TION TARGET Two special projects. the hospital-based family planning program and the armed forces program, has greatly contributed to the increasing acceptance in female and male sterilization respectively. From January-September 1974, 28,773 sterilizations were performed. During the same time in 1975, 46,894 were performed; a 63% increase. If this trend continues, by the end of 1975. approximately 70,000 sterilizations will have been performed. Sterilization is a much better method than both the loop and pill, in terms of more effective contraceptive protection and the almost zero dropout rate. In the future, the. family planning program should continue to stress the special programs which make more sterilizations possible. In particular, it should seek to add the laparoscope techniques to facilitate female sterilization acceptance rates. 6. INCREASE NUMBER OF PRIVATE ACCEPTORS Among the current family planning users, approximately 1/3 are in the private sector and thus do not- require government subsidy. The number of private acceptors increases with increasing urbanization and economic growth. To speed this process, the government initiated the special hospital based family planning program which is utilized mostly by the private sector. However, in the future, to further hasten the increase of private acceptors, the government should encourage doctors in private practice to provide family planning services, and provide the contraceptive supplies. This way, those do utilize the private medical system will also be able to receive family planning services and pay for it. Another means of increasing the number of private acceptors, IS to greatly expand the commercial outlets for pills and condoms beyond the existing service points of drugstores, hospitals, and health centers. 7. IE&C PROGRAM The current preferred family size is nearly twice as high as needed to achieve a stable poplation. Also, a strong boy preference hinders a small family size as nearly all couples fuel they must have at least one or more sons. The IE&C program must, in the future, strive to emphasize the values of the small family and equality of the sexes. A second problem for the IE&C program to work. with in the: future is the large group of people who approves family planning, want no more children, but do not practice. The IE&C program must work to motivate these people to accept family planning And finally, for those who already practice, an IE&C program in the future must stress continuation of use. The IE&C campaign, to insure highest effectiveness, should be based on a detailed factor analysis of contraceptive discontinuance. In conclusion, Korea faces a serious unfavorable sociodemographic situation- in the future unless the population growth rate can be curtailed. And in the future, the decrease in fertility will depend solely on the family planning program, as the effect of other socio-economic factors has already been maximumally felt. A second serious factor to consider is the increasing number of eligible women due to the 1950's baby boom. Thus, to meet these challenges, the program target must be increased and the program must improve the effectiveness of its current activities and develop new programs.
