The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

The present study was aimed to isolate the bacteria producing chitinolytic enzymes including chitin deacetylase (CDA) from soil origin. About 24 bacteria were screened for their chitinolytic enzymes producing ability on the basis of colloidal chitin. Amongst one of the most potent isolates designated to JI-02 was further selected as the most prominent chitinolytic and CDAlike enzyme (CDA-X) producer based on the ability of deacetylation of an artificial substrate pNP-acetamilide. The maximum production of CDA-X in crude enzyme from JI-02 was observed in the presence of 1% colloidal chitin at 37°C and pH 6.4 after 120 h of incubation. Potent enzyme activity of CDA-X was determined toward pNP-acetamilide, demonstrating that optimal pH, temperature and ionic strength of the CDA-X were assessed to be 7.0, 52°C and 125 mM, respectively. Unexpectedly, Nacetylglucosamine (GlcNAc) was not fully converted by the action of CDA-X to glucosamine (GlcN) under the established conditions. Further study on enzyme activity toward chitin-oligosaccharides consisting of multi-N-acetylglucosamine (GlcNAc)n, n=2-5 may be necessary to elucidate the mode of action which requires the minimum size of (GlcNAc)n. However, our data suggest that CDA-X can convert chitin to chitosan with the maximum yield of approximately 0.08g/L during the fermentation of the strain in the presence of chitin. Furthermore, we found that crude enzyme showed the significant chitosanolytic activity. Taken together, our data suggest that the strain JI-02 may be a potential candidate as a particular strain for better understating of chitin catabolic pathway.

It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.

미국 캘리포니아 San Joaquin Valley 농업관개수에서 회수한 Sodium Sulfate의 균염성 염료 조제로의 재활용

정지윤 服飾文化學會 2003 服飾文化硏究 Vol.11 No.3

Agricultural drainage salt generated during irrigation of crops in San Joaquin Valley, California, exceeds 600,000 tons annually and cumulates in the field in a rapid rate. As a result, the waste is taking out more farmlands for salt storage and disposal, imposing serious concerns to environment and local agricultural industry. In searching for a potential solution to reduce or eliminate the waste, this research explored feasibility of producing a value-added product, sodium sulfate, from the waste and utilizing the product in textile dyeing. The results indicated that sodium sulfate could be produced from the salt and could be purified by a recrystalization method in a temperature range within the highest and lowest daily temperatures in summer in the valley. The recovered sodium sulfate sample, with purities ranging from 67% to 99.91, were compared with commercially available sodium sulfate in the dyeing of levelling dyes with nylon/wool fabrics. In nylon/wool fabrics, C.I. Acid Yellow 23 had similar exhaustions among Na_2SO_4 Ⅰ, Na_2SO_4 Ⅱ, Na_2SO_4 Ⅲ and Na_2SO_4 Ⅴ which had similar ratios of sodium sulfate and sodium chloride in recovered salts. Na_2SO_4 Ⅳ had low exhaustion which had low ratios of sodium sulfate and sodium chloride. In nylon/wool fabrics, C.I. Acid Blue 158 had similar exhaustions among Na_2SO_4 Ⅰ, Na_2SO_4 Ⅱ, Na_2SO_4 Ⅲ and Na_2SO_4 Ⅳ and Na_2SO_4 Ⅴ despite of Na_2SO_4 Ⅳ had low ratios of sodium sulfate and sodium chloride. Generally, the dyeing of levelling dyes using recovered salts from farm drainage has similar or low exhaustion than the dyeing of levelling dyes using commercial sodium sulfate.

정두훈,윤도준,유희정,송지영 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.2

저자들은 정 신분열병 환자에서 risperidone에 의해 유발된 조증, 경조증 각 1례를 경험하였기에 국내에서는 최초로. 문헌고찰과 함께 보고한다. 증례 1은 22세의 여자 긴장형 정신분열병 환자로 3년전 발병 당시 약물치료후 유지요법 없이 지내다가 4∼5개월 전부터 사회적 위축, 식사량 저하. 말수가 줄어드는 등의 음성증상이 심해져 외래에서 risperidone 2mg을 일 주일간 처방하였다. 환자는 약물순응도가 낮아서 모두 6회에 걸쳐 억지로 투약하여 이 기간에 총 6∼8mg복용후 2∼3일 만에 조증이 발생되었다. 입원후 risperidone을 중단하고 lithium과 고용량의 정형 항정신병약물(chlorpromazine 1200mg 또는 haloperidol 20mg)을 10일간 투여하여 일부 조증이 호전되었다. 증례 2는 29세 남자로 3년 전부터 피해망상, 독극망상을 보이는 망상형 정신분열 병으로 항정신병약물을 처음 투여한 환자였다. 38일간 2mg 사용 시에는 양성증상 및 음성증상의 호전을 보이다가 3mg으로 증량된 후 일 주일만에 뚜렷한 경조증을 보였다. Risperidone을 중단하고 chlorpromazine 300mg을 투여하자 5일 만에 경조증이 완전히 회복되었다. 두 예 모두 risperidone 단독투여에 의한 것이었고, 기분안정제 병합투여, 약물남용 정신질환의 병력이나 가족력, 동반 신체질환은 없었다. Risperidone의 세로토닌(5-HT₂) 차단효과는 도파민(D₂) 차단작용과 함께 정신분열 병에서 음성증상과 정동중상을 호전시킬 뿐 아니라 항우울효과를 나타내며. 일부 환자에서 조증 및 경조증을 유발시키는 것으로 보인다. 기분장애와 분열정동장애에서도 risperidone에 의해 조증이 유발 또는 기존 조증중상이 악화되었다는 증례보고가 있고. 강박장애 등 다른 정신질환으로도 적응증이 확대되고 있으므로, 임상의들은 드물지만 이런 정신과적 부작용의 발생 가능성에 대해 알아야 하겠고. 특히 기분장애나 분열정동장애에서 사용할 경우 기분안정제의 병합투여와 최소 치료용량으로 서서히 증량할 것을 권하는 바이다. 또한 조증유발의 위험인자가 있는 경우는 기분안정효과가 있는 clozapine의 사용이 권장된다. We report the first two cases of manic and hypomanic episodes respectively induced by risperidone treatment done to schizophrenics in Korea. One case was a 22-year-old woman with catatonic schizophrenia. Since 3 years ago, she had shown psychotic symptoms, but with was poor treatment compliance. She had mainly negative symptoms such as social withdrawal, decreased food intake, mutism, and symptoms had been worsened since last 4-5 months. Prior to closed ward admission, she was prescribed 2mg/d of risperidone for a week at OPD. Two days artier taking medicine totally 6-8mg, she revealed manic features. After hospitalization, risperidone was discontinued and then, lithium 900mg/d and high dosage of conventional antipsychotics(chlorpromazine 1200mg/d or haloperidol 20mg/d) were prescribed . About on the l0th day of hospitalization, there was limited improvement of her manic symptoms. The other case was a 29-year-old man with a 3-year history of paranoid schizophrenia. He was never exposed to antipsychotics before. His main symptoms were delusions of being poisoned and of persecution. His positive and also negative symptoms were alleviated by 38 days of risperidone 2mg/d trial. However, one week after dosage increment to 3mg/d, hypomanic symptoms appeared. Risperidone medication was discontinued and was replaced by chlorpromazine 300mg/d. The hypomanic episode was resolved over 5 days. In both of the two cases, manic episodes occurred by monotherapy of risperidone without mood stabilizer, and there were no history of substance abuse and other psychiatric disorders, family history of psychiatric disorders, and comorbid physical illnesses. It is hypothesized that the potent blockade effect on serotonin(5-HT₂) receptor of risperidone causes antidepressant effect as well as therapeutic effect for negative and affective symptoms in schizophrenia. Risperidone would induce manic or hypomanic features in schizophrenic patin of preexisting manic symptoms by risperidone treatment in mood disorder and schizoaffective disorder. Risperidone is being used more widely, even for obsessive-compulsive disorder and other psychiatric disorders. It is necessary for clinicians to recognize manic switch, one of psychiatric side effects by risperidon trial. It is recommended that the combination of mood stabilizer wish risperidone or usage of talc minimum effective dose of risperidone may bewefal especially in the patients with mood disorders or schizoaffective disorders. Clozapine which has mood-stabilizing properties is also beneficial in risk groups of risperidone-induced mania.
