Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

Kim, Si-Hyung,Choi, In-Sun,Cho, Jin-Hwa,Park, Eun-Ju,Jang, Il-Sung,Choi, Byung-Ju,Kim, Hyun-Jung,Kim, Young-Jin,Nam, Soon-Hyeun The Korean Academy of Oral Biology 2006 International Journal of Oral Biology Vol.31 No.2

Dysplasia-associated seizure disorders are markedly resistant to pharmacological intervention. Relatively little research has been conducted studying the effects of antiepileptic drugs(AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate(MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of AEDs in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed and age-matched vehicle-injucted control animals. Field potential recordings were used to monitor amplitude and numbers population spikes, and paired pulse inhibition in response to stimulation of commissural pathway. Two commonly used AEDs were tested: diazepam 5, 2.5mg/kg;phenytoin 40, 60mg/kg. Diazepam(DZP) and phenytoin(PHT) reduced the amplitude of population spike in control and MAM-exposed rats. However, the amplitude of population spike was nearly eliminated in control rats as compared to the MAM-exposed rats. Pharmaco-resistance was tested by measuring seizure latencies in awake rats after pilocarpine administration(320mg/kg, i.p.) with and without pretreatment with AEDs. Pre-treatment with PHT 60 mg prolonged seizure latency in control rats, but not in MAM-exposed animals. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard AEDs assessed in vivo. These data suggest that animal model with cortical dysplasia can be used to screen the effects of potential AEDs.

1. Significance of "Saemaul undong,,. The saemaul undone is Korean type of the community development project that has undergone wide-spread success in developing countries throughout the world in recent years. "Saemaul undong, which is based on traditionally cooperative spirits among Koreans has been initiated and guide-lined by president Park of the Republic of Korea. In october 1970 the Saemaul pilot projects were conducted with emphasis on farm and fishery communities across the country by the Ministry of Home Affairs. With successful experiences from pilot projects, nationwide "Saemaul undong, was positively and actively tried by the Central "Saemaul undong,, coordination Board which is staffed with representative of appropriate Government agencies concerned in 1972. "Saemaul undong,, is, in brief, a movement for prosperous life in future. In other word, it is a voluntary effort of not only an individual or a group of people but the entire society for their common good. This nationwide movement should be spiritually based on diligence, self-help and cooperation of the participating individuals, groups or units so that they can try to achive better home, prosperous community and strong nation. In the implementation of "Saemaul undong, when any problem arises or exists, plan is made by villagers on a voluntary basis to solue such problems with their own resources and manpower. However, when necessary or the problem is beyond the villager's financial or technical capabilities, they are supported by the Government financially or technically. "Saemaul undong,, can be put into three main projects such as spiritual enlightenment, environmental improvements and income growth through increased production. Emphasis was placed on environmental improvement project untill 1973. From 1974 on, "income growth through increased production,, has been emphasized not only in rural areas but also in some of urban regions. Long-range plan of "Saemaul undong,, is as follows : A. "Saemaul undong,, is implemented at three different stages as listed below. (1) Stage I This stage may be called "Stage of foundation construction,,.(1971-1973) At this stage spirits of "saemaul undong,, are gradually encouraged to the participants through basic environment improvements or other easy projects. (2) Stage II-self-help and developing stage belongs to here (1974-1976). At this stage, production foundation is expanded, assisted with the accomplishment of the standard rural environment. (3) Stage III-"This stage can be expressed as Independent and completion stage,, (1977-1981). A total of 34,665 farm villages throughout the country will turn into the standard farm village through increased farm production and income from other sources. B. Each village is classified into one of the three different groups according to it's developmental level, namely underdeveloped villages, developing villages and developed villages, and each village is promoted to next developmental title, depending on progress of development. C. Each of 34,665 villages is classified into one of the following patterns, according to it's tophographic location or other conditions, deeply mountainous villages ; medium mountainous villages; plain villages; fishery villages; suburban villages Suitable development method are used according to its pattern. d. Considering that progect on a basis of a village unit is completed, a joint cooperative project is encouraged under the participation of several villages in a given area. "Saemaul undong,, which was ignited only five years ago, resulted in miraculous results which could not have been achieved for a few centuries in the past, changing farm villages as well as urban societies structurally and functionally. It has changed thought and way of living of the community residents, and remarkedly contributed to increase of the income and welfare of the people. 2. Achievements of Saemaul Undong During the five years, the number of participants in 34,665 villages and 35 cities has approxmated to 332 million. The total number of projects completed during this period reached 4,495,000. Furthmore, the total worth produced by this movement was 2.5 times as great as the total amount of the government assistance. The effects of Saemaul undong are as follows : 1) Improvement of Environment : The environmental betterment project has contributed to the development of enthusiasm and the sense of self-help. One of the remarkable things is that the basic establishments for the modernization of the country have been already made. Most of the rural areas have been electrified. Telephones are installed in many villages. Makeshift water supply systems which supply clean and sanitary water to the villagers have been installed. The transportation networks have been readjusted and extendeded rural areas, connecting through the highway. Such public establishments as storehouses, marketplaces, village assembly halls, public bathrooms, and public libraries have been established in the rural villages. 2) Increase in Income (1) The movement provided the strong basis for production and income-increase. The expansion of transportation networks including the construction of village and farm roads propelled both the improvement of transportation and marketing systems and the mechanization of farming ; the provision of irrigation farilities and the consolidation of farmlands improved the agricultural structure : the electrification and communication facilities of the rural villages enabled to extend the productive activities and flows of products. In the view of the increase in food production, Korea has experienced a revolution of "Tong-Il" variety species. Along with which, the government has supported various projects such as expansion of the base far agricultural production, mechanization of agricultural production, scientific methods of fertilization, farm technology, and top-soil improvement. As a result, the nation has achieved the historical record of rice production from 4.45 million tons in 1974 to 4.67 million tons in 1975. (2) The movement established the cooperative production system. (3) The movement employed the unemployed lobor in the rural region. Most of the unemployed people in the communities were mobilized to participate in a lot of saemaul projects and related income projects, particularly the wage-reinvesting projects and saemaul factories have greatly contributed to attracting the idle labor force. 3) Spiritual Enlightenment of the people. The philosophy of the Saemaul undone is based on the spirit of diligence, self·help, and cooperation. The new spiritual awakening of the people Financial inputs to "Saemaul Undong" ◁표 참조▷ p. 460 Table 2 Project Achievements of "Saemaul Undong" ◁표 참조▷ p. 461 have laid the spiritual basis for the renewal of the economic environment. The hearts of the people are stirring with enthusiasm and desire for the new economic environment. The basis for the modernization of the country has matured through the spiritual enlightenment. 3. Evaluation on achievements of Saemaul Undong(case study) In order to precisely evaluate and analyze achievements of "saemaul undong" sampling study for the entire nation is required. However it will be a attemped in the studs to be followed. In this study, deep mountainous villages, which are relatively adversely located, were selected as sample. They are seven villages located in the jurisdiction of choong song Puk to province, as shown below. ◁표 참조▷ p. 461 DANYANG Gun (county) of CHOONG PUK province occupies 10.6% of the province in size, and is mostly mountainous (83.7%) with arable land of 12.8%. Total farm house-hold is 64%, and remaining 36% is non-farmer. Data were collected through interviews with village chiefs and leaders during the period of 26-28 Jan 76. Evaluating criteria were put into the two main divisions, namely promising factors and project achievements, and the two were further, sub-divided for point, as follows ; 1) Promising factors : Resident's participation, planning, organization and operation, leaders and their leadership, operating funds 2) Project achievements : Improvement of the cultural environment, food production, income growth project, cooperative project, improvement of living conditions. (Table 3) Total ◁표 참조▷ p. 462 These evaluating factors differ from each other in importance, a different weight has been multiplied for each factor. Weight has been determined in order of importance expressed by the village leaders during the interviews. Summarized below are results of the investigatin : 1) Promising factors : Residents were willing to participate in, and adequate number of leader was working, Howeer, majority of villages are in short supply of operating funds. 2) Project achievements : Enviromental improvements were remarkable, but progresses in the fields of production and income were insgnificant. Overall points based on valuating factors are shown in the table below. Therefore, village funds will have to be accumulated, and also emphasis should be placed on increase of income.

Objectives: Epstein-Barr virus (EBV) has been known to be linked to a spectrum of neoplastic conditions, including nasopharyngeal carcinoma, Burkitt's lymphoma, peripheral T-cell lymphoma and Hodgkin's disease. This study aims to investigate the association of EBV with gastric carcinoma in Korea. Methods: Fifty-three cases of gastric adenocarcinoma were studied for evidence of EBV infection by EBV-encoded small RNA (EBER) in situ hybridization (ISH) on the paraffin sections and amplifying the EBV genome encoding envelop glycoprotein (gp220) with polymerase chain reaction (PCR) in fresh gastric cancer specimens. Results: EBER was detected in 7 (13.2%) of 53 gastric carcinomas and all cases were male. In 6 (85.7%) of 7 EBER-positive cases, the tumors were located in the upper and middle part of the stomach. EBER ISH study showed strong positivity in all the tumor cells, but negativity in surrouning lymphocytes, stromal cells and normal gastric mucosa. DNA PCR was positive in 23 (43.4%) of 53 gastric carcinomas, including all of 7 EBER-positive cases. Conclusion: We could observe some association of EBV with gastric carcinoma, and our findings about the charateristics of EBV-positive gastric cancers involving sex, site and histological type are similar to those in Japan. However, EBV-positive rate of gastric cancer is higher than in Japan and lower than in Western countries. Further studies to elucidate oncogenic mechanism of EBV in gastric cancer should be performed.

The purpose of this study is to grasp the change of consciousness of young people in order to seek new approach of policy for aged era. 1,200 students attending collages and universities in three small or medium sized cities were inquired for 2 months, from October 1 to November 30, 1996. The result is as follows. 1. The characteristic of the respondents of this survey is that they include 72.1% of women, 40.4% of people aged between 20 to 21, and 49.1% of people who do not have any religion. Those who are from big cities and those who are form farming villages or fishing village occupy equally 40.2%, those who reside in that cities for a long period 49.0%, and those who live with their family 60.9%. 2. The family feature of the subject is that 31.5% of them are those whose father is the age of 55 and more than 55, 10% of them are those whose mothers age is so, 33.1% of them have 5 family members, 29.5% of them have the family income of 1,000,000 to 1,490,000 won, 83.9% of them are from middle class, 47.7% of them are the people whose grand parents have passed away, 70.4% of them live apart from their grand parents, and 60.9% of them are second child. 3. 64.0% of males, 70% of respondents who are aged over 24, 58.1% of respondents who are from rural communities, 62.4% of respondents who live in rural area, and 58.3% of respondents who live alone, prefer to live with grand parents, marked higher rate than other groups. The groups whose father and mother are the age of more than 55 marked higher rate of 55.9% and 58% each than any other groups(p<0.05). The groups whose family member is less than three, whose grand parents both have passed away in middle class, who live with their grand parents, and who are second children, give more positive answers than any other groups. 4. Those who are older, who are buddhists, who are from rural area or live in rural area, whose family is small, whose family income is small, who are from lower class and whose grand parents are still alive, shows preference to support their parents after marriage. 5. Females(89.4%), those who are from small or medium sized cities(89%), who live with their family(85.6%), whose father is the age of 55 and more than 55, whose mother is the age of 54 and less than 54, whose family member is 6, who are from middle class, whose grandparents are still alive and who are the eldest child in their family, give more response that they prefer to live apart from their children in their old age than any other groups. 6. What elderly people need most right now is past time(42.3%), and the respondents whose age is 20 to 21, who are buddhists, who are from middle sized cities and live alone, whose parents are the age of more than 55, who have small family income, who live with their grand parents and who are second children show higher level than any other groups. 7. 76.8% of respondents answer that they do not need their parent's fortune, marked still higher rate than the opposite answer. Those who are older, who are buddhists, who are from big cities, who reside in rural area, who live alone and have smaller family, who are in bad family economic conditions and who live with grand parents present higher rate of positive response. 8. 59.3% of respondents reply that they think about death from time to time, and those who are female, who are in the age of 20 to 21, who are christian, who live with their family, whose siblings or other family members offer their education expenses show higher rate than any other groups. 9. 92.3% of respondents answer that the budget for welfare facility for elderly people is very small. The younger the respondents are and the worse economic condition they have among those who live in big cities, the more answered that. 10. 50% of respondents think social security should provide for their old age, and 42.8% of them believe they themselves provide against it. The respondence that social security ought provide for it appeared more among those whose age are over 24, who are female, who reside in rural area, who are christian, who are in bad economic condition, and who ever used medical institutions in recent one month, marked higher level than other groups. 11. The adequate time of retirement is 59.97±5.60 for public officers, the highest and 59.28±6.35 for teachers, the next. 12. 35.2% of respondents reply that the adequate budget for the old age after their retirement at the age of 60 is 220 million won, showed the highest level of respondence. 13. The factors which affect on the old people in the charged welfare facilities are sex(p<0.01), the type of housing(p<0.05) and whole family income(p<0.05). 14. The factors which affect on remarriage are sex(p<0.05) and religion(p<0.05). For varying old population and expanded welfare service for them, government and relevant authority should give more attention to secure the budget, establish effective plans to expand various program and the facilities for elderly people in order that elderly people spend the rest of life time more happily and more fruitfully. To do that, each college and university should open Health courses, and educate and inform about health and welfare.

This study was designed to observe in rats the possible harmful effects through the processing of fish flour(englaulis japonicu). The experimental animals were 66 male albino rats to be weaned, and they were divided into 11 groups according to the kinds of diets. Each of the 11 kinds of diets contained rice, 81.3%-86%, supplemented with the following substances thereto so as to contain 12g of protein and 370㎉/100g. Supplements: 1) fish flour 2) the extracts or residua of fish flour, obtained by extracting with either 76% or 96% and both of them of ethanol 3) the mixtures of the extracts and residua 4) casein After feeding the rats on corresponding diets for 40days, the activities of alkaline phosphatase, glutsmic pyruvic transaminase(GPT) and glutamic oxaloacetic transaminase(GOT) in the liver, kidney and serum were determined. The results obtained from the study are summarized as follows: 1. In the liver, the enzyme activities are lower each group of the diets treated with ethanol than in the group of 10% fresh fish flour diet. 2. In the kidney, alkaline phosphatase activity is higher, but GPT and GOT activities are lower in each of diets treated with ethanol than in the group of 10% fresh fish flour diet. 3. In the serum alkaline phosphatase and GPT activities are lower in each group of diets treated with ethanol than in the group of 10% fresh fish flour diet. The above results lead to the conclusion that the treatment of fresh fish flour with ethanol has some harmful effects on the nutrition.

Biphenyl diinethyl dicarboxylate(DDB) is a synthetic analogue of SchiBandrin C isolated from SchiBandrae Fructus and has been widely used for its hepatic protective effect. This study has beenundertaken to examine the effect of DDB on rat liver drug metaboliEing enzymes and to understand theprotective mechanism of D:DB against carbon tetrachloride(CCl4) -induced hepatic toxicity in rat liver.After DDB was administered into male rats for different periods of time(1 ~7 days) ana with differentdoses(25, 50, 100 and 200mg/kg), mRNA levels of CYPIAI and CYPaHl were measured by polymerasechain reaction (PCR) and also assayed the activities of CYP IAI specific ethoxyresorufin-o-deethylase(EROD) and CYPfBl sf)ecific benzyloxyresorufin-o-dealkylase (BROD) . Furthermore, rats werepretreated with DDB 25, 5() and 100 mg/ltg daily for 4 days, 3-hours after final treatrneBt on the 4thday, CCI, 0.3mf/kg was intraperitonially injected into the rats. Activities of serum aminotransferaseswere assayed and determirled lipid peroxidation(production of ualondialdehyde) in hepatic microsomeand done histopathological examination. DDB treatment resulted in increase in CYPaBl mRMA leveland BROD activity whereas there was no change in CYPIAI niRNA level and EROD activity. This ef-fect of DDB was time and dose dependent reaching maximal level by 3 day and 200mg/kg treatment.Based oi?'studies of serum ALT level and lipid peroxidation, D:DB SOmg/kg pretreatinent appeared themost effective protection against CCI,-induce4 hepatotoxicity. :However, histopathological examinationdid not significantly show any improving effect on balloning degeneration and necrosis caused by CCI,treatment. These results in.dicate that DDB stimulates CYPEBI ruRNA level and BROD activity in timeand dose dependent manner and suggest protective effect of DDB against CCI,-induced hepatotoxicitymight be exerted through free radical scavenging. In addition, we have also investigated the effects ofrhein, ephedrine and baicaBin on hepatic toxicity and metabolism in rat liver in order to compare withtheir natural products f·hick are Rhei Rhizoma, Ephedrae Hel·ba and Scutellariae Radix, respectively.After rhein 20 and ephedrine 10mg/kg were intraperitonially injected into the rats daily for 4 daysrespectively compared as bacaBin was treated orally for 7 days, the expression of CYPIAI and CYPfBlwere examined and tlleir dependent EROD and BROD activities were assayed. The levels of serumaainotransferases and hepatic rnaiondialdehyde(MDA ) were Beasured as well. Ephedrine treatment in-creased in CYPIAI specific EROD activity and the ratio of serum ALT/AST ratio, a marker of chronichepatitis(p <0.01).

Abstract-In order to investigate the phamacological properties of New Wonbang Woohwangchungsimwon Pill (NSCH), effects of Wonbang Woohwangchungsimwon Pill (SCH) and NSCH were compared using various experimental models. In rat aorta, NSCH and SCH made the relaxation of blood vessels in maximum contractile response to phenylephrine (10^-6 M) regardless to endothelium containing or denuded rings of the rat aorta. Furthermore, the presence of the inhibitors of NO synthase and guanylate cyclase did not aftect significantly the relaxing effects of NSCH and SCH, NSCH and SCH inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs). NSCH and SCH decreased significantly heart rate. These, at high doses, had a negative inotropic effect that was a decrease of left ventricular developed pressure and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In guinea-pig papillary muscle, these had no effects on parameters of action potential such as action potential amplitude (APA). V_max and resting membrane potential (RMP) at low doses, whereas inhibited the cardiac contractility at high doses. Furthermore, these had a significant inhibitory effects on palpitation of the heart in normotensive rats and SHRs. These results suggest that NSCH and SCH have weak cardiovascular effects, and that there is no significant differences between cardiovascular effects of two preparations.
