본 연구에서는 KI-188 칼슘과 KI-180 조성물이 성장발육에 미치는 효과를 조사하였다. 시험기간중 KI-188 칼슘과 KI-180 식이군이 대조군 보다 성장률과 평균 식이섭취량은 증가하였다. 체장은 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 평균 3.55 mm 더 길었고, 등뼈길이는 KI-180 식이군이 대조군 보다 통계적인 차이는 없었지만 0.5 mm 더 길었다. 대퇴골 무게는 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 통계적으로 무거웠으며, 대퇴골길이는 대조군에 비해 각각 평균 0.89, 1.09 mm 더 길었다. 혈당, 총콜레스테롤 및 중성지방 농도는 차이가 없었고, 칼슘농도는 KI-188 칼슘과 KI-180 식이군 보다 대조군이 유의하게 높았다. 백혈구와 혈소판수는 차이가 없었고, 적혈구, 혈색소 및 헤마토크릿치는 대조군이 KI-188 칼슘과 KI-180 식이군 보다 통계적으로 높았다. ALP활성은 KI-180 식이군이 대조군 보다 통계적으로 높았고, osteocalcin농도는 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 통계적으로 유의하게 높았다. 혈청 testosterone 농도는 KI-188 칼슘과 KI-180 식이군과 대조군 간에 차이가 없었다. IGF-1과 IGFBP-3 농도는 KI-180 조성물이 대조군 보다 각각 20%, 11% 정도 유의하게 더 높았다. 이상의 결과를 검토할 때 KI-188 칼슘과 KI-180 조성물은 어린쥐의 성장과 골격의 발달을 촉진시키고, 성장호르몬의 분비능을 양적으로 유도하여 전반적인 성장발육에 유효한 작용이 있는 것으로 사료된다. Herbs have active components that promote the growth rate of both animals and human. The KI-180 and KI-188 calcium food formulae contain Acanthopanacis cortex, Bombysis corpus and hoelen, seaweed calcium, chlorella extract, spirulina, colostrum powder, and other natural and functional components. We evaluated the growth-promoting effects of these formulae by analyzing the weight, femur and backbone, alkaline phosphatase, osteocalcin, testosterone, insulin-like growth factor (IGF)-1, and IGF binding protein-3 (IGFBP-3) of growing rats. Growing rats administered with KI-180 and KI-188 calcium showed the increase of body weight, body length, and femur weight and length of growing rats. In addition, administration of KI-180 and KI-188 calcium increased the alkaline phosphatase activity, the levels of osteocalcin and the growth hormones IGF-1 and IGFBP-3 of growing rats. The impact of KI-180 and KI-188 calcium on the physical development of growing rats suggests that the incorporation of these food formulae in the diets of growing children may promote the physical development.

Hypoxia Enhances Nitric Oxide Synthesis by Upregulation of Inducible Nitric Oxide Synthase in Endothelial Cells

Ki?Jong Rhee,Sun-Yeong Gwon,and Seunghyung Lee 대한의생명과학회 2013 Biomedical Science Letters Vol.19 No.3

Hypoxia is an integral part of the environment during luteolysis. In this study we examined whether hypoxia could directly stimulate endothelial cells to produce nitric oxide (NO). Endothelial cells were cultured in hypoxic (5% O₂) or normoxic (20% O₂) conditions and the levels of total NO, inducible NO and endothelial NO was measured. We found that hypoxia but not normoxia upregulated NO production. The increased NO levels correlated with increased inducible NO synthase (iNOS) expression whereas expression of endothelial NOS (eNOS) expression remained constant. Addition of the iNOS specific inhibitor 1400W to hypoxic cultures prevented NO production suggesting that hypoxia?induced NO production in endothelial cells was due mainly to upregulation of iNOS. We also found that prostaglandin F2α (PGF) production was unaffected by hypoxia suggesting that upregulation of NO was not due to increased synthesis of PGF. In summary, we report that endothelial cells cultured under hypoxic conditions produce NO via the iNOS pathway. This study provides the importance of the relation between the hypoxic environment and the induction of NO by endothelial cells during regression of the corpus luteum in the ovary.

종합검진센터 내원자에서 관상동맥질환 위험요인들의 분포

이충원,이종영,박종원,윤능기,김영조,이현우,이무식,서석권 啓明大學校 醫科大學 1993 계명의대학술지 Vol.12 No.3

1991년3월부터 8월사이에 대구시에 소재한 1개의 대학병원의 종합검진센타에 내원해서 종합검진을 받은 남자 422명(69.9%)과 여자 182명(30.1%)을 대상으로 하여 심헐관계질환의 위험요인들의 전체적인 분포를 보았다. 평균 연령은 남자가 43.3(표준편차, 10.3), 여자가 44.4(표준편차, 10.8)였다. 남자에서 연령에 따라 0.05 수준에서 통계적인 유의성을 보인 위험인자는 혈청 총콜레스테롤(TC). 트리글리세라이드(TC), 고밀도 지단백콜레스테롤(HDL), 저밀도 지단백콜레스테롤(LDL), 수축기혈압, 비체중, A형행동양상이었으며 생활습관으로서는 음주, 흡연, 규칙적인 운동, 우유와 커피섭취, 수면 등이었다. 여자에서는 TC, TG, LDL, 수축기와 확장기혈압, 비체중 그리고 커피섭취와 수면 등이었다. 남자에서 총콜레스테롤의 평균은 181.7mg/dl(표준편차, 32.2), 여자는 182.5mg/이(표준편차, 42.2)였다. 대부분의 위험인자들은 구미의 수준에 미치지 못했으나 남자에서 흡연율이 전체적으로 61.8%로 높으 수준이었으며 특히, 20~29세가 72.9%, 30~39세가 75.2%로서 다른 연령군에 비해 상대적으로 높았다. 여자에서는 전체적으로 6.0%에 지나지 않았다. 확장기혈압 90mmHg 이상을 고혈압자로 정의했을 때의 유병률이 여자 전체대상자에서 24.7%로 높았으며 50-59세는 표본수가 적어서 문제가 되었으나 53.1%였다. 어떤 인구집단내에서 총콜레스테롤의 평균이 200mg/dl 미만이면 고혈압과 흡연의 인구집단의 수준에 관계없이 관상동맥질환(coronary heart disease)의 발생은 드문 것으로 보고가 되고 있으므로 당분간 관상동맥질환 발생률의 급속한 절대적인 증가는 힘드리라 사료된다. 그러나 이러한 결과는 본 연구의 대상자들이 대표성을 지니지 못하며 건강검진센터에 자발적으로 내원한 사람들이므로 해석에 주의를 요한다. Authors examined the distributions of the risk factors for the coronary heart disease in the 422 male (69.9%) and 182 female (30.1%) visitors to the health examination center of a university hospital located in Taegu March to August 1991. Mean age of males was 43.3(standard deviation, SD 10.3) and that of females was 44.4(SD 10.8). Total cholesterol(TC), triglyceride (TG), high-density lipoprotein and low-density lipoprotein cholesterol(LDL), systolic blood pressure, Quetelet index, and Type A Behavior Pattern, and some of life habit variables(alcohol intake, smoking, regular exercise, milk and coffee intake and sleeping) were statistically significant in age groups of the males(P<0.05). In the females, TC, TG and LDL, systolic and diastolic pressure, Quetelet index, coffee intake and sleeping were statistically significant in age groups (P<0.05). Mean of total cholesterol was 181.7㎎/dl(SD,32.2) in males and that of females was 182.5㎎/dl(SD,42.2). Most of the risk factors levels were lower than the Euro-Americans', while smokers were high with 61.8%, especially 72.9% in 20-29 age group and 75.2% in 30-39 age group in males. In females, smokers were just 6.0%. Hypertensives defined by more than 90mmHg diastolic pressure were 24.7% in females, particularly 53.1% in 50-59 age group, but size of the strata was rather small(N=49). In the light of the report that coronary heart disease is uncommon irrespective of population levels of smoking and hypertension, where average total blood cholesterol level in a population is low(<200mg/dl), it is not likely that the absolute increase of the number of the coronary heart disease will increase markedly in the near future. But cautions should be exercised in interpreting the results of this study due to the lack of representativeness and volunteerism. .

Although numerous studies have shown that cadmium disturbs the normal biological processes in central nervous system the mechanism of toxicity is not well understood The present study has investigated the effect of cadmium on oxidative stress, Na+/K- ATPase activity and the aggregation of amyloid beta peptide(β-amylotd) in neuronal cell Ime, HT22 cell LC_(5) and LC_(50) of cadmium for HT22 cell resulted from MTT assay was 4 1 μM and 9 5 μM, respectively Cadmium(2 to 8 μM) dose-dependently increased the lipid peroxidation and decreased the content of glutathione Cadmium 4 μM showed a significant decrease in Na^(-)/K^(+) ATPase activity as compared with control group The aggregation of P-amyloid was accelerated in a dose-dependent manner by the treatment with 2 to 8 μM cadmium These results suggest that the neurotoxicity of cadmium can be mediated by the increase in oxidative stress and decrease in Na^(-)/K^(+) ATPase activity.

The main purpose of this study is to find city identity factors of Kunsan. To find local identity in today, maps were analyzed to examine formation of landscape and buildings. To find out landscape transition in Kunsan, we have analyzed the important time of city organization development by using past maps and literature. The maps used in this study were made in 1899, 1902, 1906,1911, 1916, 1923, and 1935s. Teh results are as follows : Something that modernized Kunsan city was General Foreign Settlement after opening its port. This is because they needed to export rice to Japan. Japanese had monopoly in General Foreign Settlement. Residential areas were developed into two divisions and provincial office was moved to Middle street. It led the city to expand to east-south areas. For convenience of exporting rice, harbor facilities were filled up. And by making recourses, the city was expanded to east. Buildings were constructed in groups at Haemang-dong, Walmyong-dong, and Jungangro. Important buildings include the Kunsan custom house, the police station, Nakasaki 18 bank, Dongkik temple, Chosun bank, Lee,yong-chun’s house, the Hyros’s house, and Walmyong-dong Japanese style houses. This study on transition used using map analysis but the accurate boundary of important relics will be necessary in more deeply study.

This study was conducted to examine both actual status and understanding of the workshop environment of the small sized companies with 30 or less employees in and around Taegu city, Korea by analysing the questionnaire with 400 small sized manufacturing companies from the end of Mar. to the end of June 1993 according to their employee number and business type. The result of this study is summarized as follows. The job title of the respondents showed that the president accounted for 34.3% which was highest, particularly, which showed the highest percent in the companies with 5-9 employees. The management of workshop environment indicated that the response of 'Very Necessary' accounted for 52.0% which was higher. Thus it was shown that the owner and manager's understanding of the workshop environment was higher. However, the response of 'No Enough Money' for investment in improvement of workshop environment indicated that the president accounted for 51.1% which was also higher. 54.3% of all subjects considered their workshop environment as not good, while 66.5% answered that the workshop environment has effect on the health of employees. The actual status of industrial accidents occurred from January to December 1992 showed 18.7% frequency, while their business type was that the metal and machinery industries accounted for 24.8%. In addition, their size indicated that 16-29 employees accounted for 26.5% which was higher than that of other companies with different sizes. Regarding the question of understanding whether their workshop is the subject required for measuring the workshop environment, it was shown that the response of 'No Understanding' accounted for 57.0%. Based on their size, the companies with 5-9 employees accounted for 37.6%, while on their business types the metal and machinery industries accounted for 31.2% which showed the lowest understanding. In case of the companies understanding as the subject required for measurement of their workshop environment, the harmful element acting as a problem in their workshop indicated that the response of 'Too Noisy' accounted for 37.8%, and 'Too Serious Dust' for 11.8%, when the noise appeared as the most serious harmful element in all workshops. Among the companies required for measuring the workshop environment, it was shown that the workshops which did not carry out the required measurement accounted for 24.4%. Of the workshops which carried out the measurement required for their workshop environment, the frequency of annual two times accounted for 40.1% which was highest. Based on their size, it was shown that the companies with 16-29 employees accounted for 52.6% which was highest. The use of their measured data and execution of required improvement showed that the response of 'Good' was totally high. Also the keeping result of their measured list indicated that the response of 'Good' accounted for 72.3%. Based on the above result, the understanding of needs for control of workshop environment was high. However, the actual improvement of workshop environment was not so active as their understanding. Because the health of all employees is closely related to the harmful workshop environment and working conditions, it will be necessary for the government to support the improvement of workshop environment of these small sized companies with insufficient capability of investment, to suggest its direction and to continuously encourage and inspect their measurement of workshop environment.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.
