Objectives : This study was carried out to suggest preventive methods for hypertension in cold-exposed workers. Methods : In 11 refs·iteration industries, 68 workers working in refrigerated areas more than one time per day were selected as the exposed group, and 68 workers not exposed to cold were selected as the control group. We interviewed the subjects with a questionnaire covering occupational history, and conducted clinical and laboratory tests including measurements of blood pressure and core temperature. Results : The systolic blood pressure in the exposed group(130.0±13.3 mmHg) was significantly higher than that recorded In the control group(118.3±12.1 mmHg), as was the diastolic blood pressure in the exposed group(82.7±8.5 mmHg) versus the control group(77.4±8.7 mmHg). The core temperature in the exposed group(36.1±0.7℃) was significantly lower than that experienced in the control group (36.4±0.5℃). In logistic regression analysis, age, cold exposure severity and milk intake were significant variables, with odds ratios of 5.204(95 % CI 1.440∼18.812), 2.674(95 % CI 1.080∼6.618), and 0.364(95 % Cl 0.141∼0.942) , respectively. Conclusions : Our study suggests that cold-exposed workers have higher a higher risk of hypertension, and that their core temperature is lower. Risk factors affecting hyper-tension of cold-exposed workers include age, cold exposure severity and milk intake. For the prevention of hypertension, cold-exposed workers should minimize cold-exposure time as much as possible.

왕송이(Tricholoma giganteum) 신품종 '백련'의 특성

장갑열 외 한국버섯학회 2009 한국버섯학회지 Vol.7 No.4

주로 고온에서 재배되는 왕송이는 온도제어기를 사용하지 않고 재배할 수 있는 잇점이 있다. 여름철 냉방시설없이 재배할 수 있는 품종을 개발하고자 국내외에서 수집된 왕송이균을 교잡하여 새로운 품종 '백련'을 육성하였다. 백련 왕송이의 균배양온도는 25℃~30℃이며 자실체 발생온도와 생육온도 거의 동일하다. 다만 배양완료 후 복토를 해야하기 때문에 2차 균사생장기간이 있어 초발이소요일수가 다소 늦다. 하지만 복토를 하기 때문에 주야간 온도차이에도 버섯발생이 용이하고 습도관리가 쉬워 여름철 재배가 유리하다. 버섯의 모양은 순백색에 전형적인 우산형으로 강한 다발성을 가지며 대가 긴편이다. 특히, 병재배보다는 봉지재배를 할 경우 다발성은 더욱 강해지면 자실체의 크기도 증가한다. 적정배지는 포플라 40%+미송 40%+미강 20%를 혼합한 배지이며 평균수량은 병재배시 101g이나 봉지재배에서는 더욱 증가할 것으로 사료된다. Tricholoma giganteum, belongs to Tricholomataceae of Tricholoma, is also well-known as the medicinal mushroom in Taiwan. " Backryon " was the first variety developed by intra-specific crossing in Korea. It was improved with hybridization between monokaryotic strain derived from MKACC50852 and MKACC 50853. The optimum temperature of mycelial growth and fruiting body development were 25~30℃ and 20~25℃, respectively. The color of fruitingbody was pure white and cap type was umbrella. It suggested that 'Backryon' was new commercial variety for small-sized cultivator during the summer season

담자균류를 이용한 폐기물연용 밭토양의 건전성 간이평가

장갑열 외 한국버섯학회 2007 한국버섯학회지 Vol.5 No.1

Application of sludge wastes into the field may help soil fertility with physical, chemical and biological properties. Efficient use of sludge waste, however, requires an individual assessment of the waste products. A lot of experiment into the organic waste-treated soils has been done for decade. However, studies have not been carried out on the assessment of agricultural soil by Basidiomycota. This study was assessed the influence of sludge application on soil healthy in agricultural upland soils. The organic wastes selected for long-term application experiment in this study were municipal sewage sludge (MSS), industrial sewage sludge (ISS), leather processing sludge (LS), alcohol fermentation processing sludge (FS), and pig manure compost (PMC). To develop the soil healthy assesment method, soil samples were diluted by 20X with distilled water. After shaking at 200rpm for 30 minutes, the shaked sample was mixed on PDA(Potato Dextrose Agar). And sterilized at 121℃ for 20 minutes. Coriolus hirsutus (MKACC 50560) was inoculated on petri-dish including PDA mixed sample. After the media was incubated at 25℃ for five days, the mycelial growth of C. hirsutus was measured. When the mycelial growth on sample media was compared with growth on media contained PDA only, well grown media contained sample soil was assesed as healthy soil. The results suggest that the simple method by Coriolus hirsutus is a handy way to assess the healthy of waste sludge-applied upland soils. 이상의 결과를 종합하면, 평가대상 토양을 증류수로 20배 희석하여 200rpm 으로 30분간 진탕한 후 PDA (감자 추출배지)와 혼합하여 121℃에서 20분간 살균한 후 Coriolus hirsutus (MKACC 50560) 균을 접종한다. 접종 완료 후 25℃에서 5일간 배양한 후 균사 생장을 측정하여 담자균의 균사 생장률 (목적토양에서의 균사생장/PDA 에서의 균사생장×100)을 계산한다. 이 기준에 따라 균사생장률이 60%이상이 되면 대상 토양은 작물 생육에 적합한 토양이라고 추정할 수 있다. 이러한 방법은 토양의 건전성 평가를 위한 신속한 간이검사를 통하여 소량의 시료를 가지고 단기간 내 대량 분석을 가능하게 하여 토양 건정성 평가의 기초 자료로 사용될 수 있다고 사료된다.

중금속 오염지 및 건전지역에서 수집된 담자균류의 분포

장갑열 외 한국버섯학회 2005 한국버섯학회지 Vol.3 No.4

미생물을 이용한 중금속 오염지의 생물적 개량연구를 위하여 구리, 납 등 중금속 오염지인 은성 폐광과 도곡 폐광 지역에서 야생버섯을 수집·동정하고 중금속 함량을 분석한 결과 Laccaria Jaccata가 가장 높게 나타났으며 토양내 중금속함량이 높을수록 버섯 내 중금속 농도도 높았다. 그러나, 전이계수를 이용하여 버섯 자실체의 중금속 이행률을 알아본 결과, Amanita volvata 가 카드뮴과 비소의 이행률이 가장 높았으며, 구리의 이행률은 Agaricus praesquamosus가 다른 버섯에 비해 월등히 높은 수치를 나타냈다. 납은 Mycena pura, 아연은 Marasmius pulcherripes, 니켈은 Laccaria laccata, 크롬은 Collybia confluens로 나타났다. 중금속 오염지와 비오염지인 치악산 지역에서의 담자균의 발생 분포를 비교한 결과, Russula 와 Collybia 속은 비오염지와 오염 지역 모두에서 발생되었으며 Leucocoprinus, Coprinus, Suillus, Lepiost, Gyroporus, Lepista, Microstoma, Stropharia, Agrocybe 속은 오염지에서만 발생되었다. 이상의 결과, Laccaria laccata 등 일부 담자균은 중금속 오염지 저감에 이용할 가능성이 있으며 이를 위한 많은 연구가 기대된다. Two hundred seventy-four microorganisms were isolated from the soil of abandoned mines around for selecting the heavy metal-degrading strains and their microbial diversity was analyzed. The specimens of macroftingi were isolated from the soil of abandoned mines around for selecting the heavy metal-degrading strains. Eunseong and Dogok in Gyeongsangbuk-do, for selecting the heavy metal-degrading strains. Soil was also collected from same location. Contents of heavy metals (Cd, Cu, Pb, Zn, Ni, Cr, and As) were determined spectrometically in fruiting bodies of forty eight wild macroftmgi specimens with soils. When the analysed their transfer factor from soil to fruiting body, Amanita volvata have the highest transfer factor of cadmium and arsenic. And Mycena pura showed the highest in mercury, Marasmius pulcherripes in zinc, Laccaria laccata in nickel, and Collybia confluens in chrome. When compare the population of mushrooms between the contaminated mines and Mt. Chiak as the healthy area, Genus Russula and Collybia were collected both area, but Leucocoprinus, Coprinus, Suillus, Lepiost, Gyroporus, Lepista, Microstoma, Stropharia, and Agrocybe were only in the contaminated mine area.

Kab-Yeul Jang,Won-Sik Kong,Young-Bok Yoo,Pyung-Gyun Shin,Yunjeong Park 한국버섯학회 2010 한국버섯학회지 Vol.8 No.4

Hypsizygus marmoreus, belongs to Tricholomataceae of Agaricales, is widely cultured as the Beech mushroom in Japan. “Haemi” is the first variety developed by intra-specific crossing in Korea. It was improved with hybridization between monokaryotic strain derived from MKACC51987-8 and MKACC51988- 12. The optimum temperature of mycelial growth and fruiting body development were 23-25℃ and 11~17℃, respectively. The color of fruitingbody was grayish brown and cap type was umbrella. It suggest that 'Haemi' is new commercial variety for consumer who concern over healthy and tasty food

Morphological Characteristics of Protoplast Fusion Strains between Pleurotus abalonus and P. ostreatus

Kab-yeul Jang,Youn-lee Oh,Min-ji Oh,Ji-hoon Im 한국버섯학회 2017 버섯 Vol.21 No.2

The production scale of mushroom cultivation in Korea is approximately 600 billion won, which is 1.6% of the Korean gross agricultural output. Annually, ca. 190,000 tons of mushrooms are harvested in Korea. The oyster mushroom is one of the most favorite and commonly consumed mushrooms in Korea. In case of breeding, the protoplast fusion technique of the oyster mushroom, P. ostreatus was first commercialized in the world. To develop the high temperature varieties, various examinations were accomplished. Protoplast fusion of abalone mushroom, high temperature, and oyster mushroom, popular mushroom, were attempted. 2 strains of P.ostreatus and 2 strains of P.abalonus were fused to each other by protoplast isolation. Fusion strains were investigated by random amplified polymorphic DNA(RAPD) marker, and selected strains were cultivated at 25°C after completing the mycelial growth. As a result of sawdust bag cultivation, most of strains showed the fruiting body, but the morphological characteristics among them were not significant different. However, these protoplast fusion strains were expected as new parents strains to develop varieties.
