  • This study was designed to investigate job stress, job satisfaction and related factors of oriental medical doctors. The survey used administered questionnaire, was conducted from June 10 to June 30, 2010 in Jeonbuk province. Questionnaire was composed of general characteristics, socioeconomic status perception, job stress scale and job satisfaction scale. Job stress was related to sex, age, marriage, working form, working time, clinical career. Job satisfaction was related to age. Working time, working form and self-status perception influenced job stress. Self-status perception influenced job satisfaction. Especially, it was supposed that working time was most important factor to job stress.

  • To elucidate the preventive effect of oriental medicine Gami-Ondamtang(GO) on stress, we investigated the physiological change of rats which were applied immobilization stress. For immobilization stress, rats were placed in restrainer for 12 hours a day for 3 days. During application of stress, body weight of rats was measured. After sacrifice, 8 organs were taken for measurement of organ weight. Brain was sectioned into 4 parts that are Frontal Cortex, Corpus Striatum, Hypothalamus and Hippocampus. Each part was homogenated and its catecholamine and serotonin contents were measured with HPLC. In our study, stress mainly induced increase of concentration of neurotransmitters in brain without other significant physical change of rats. GO inhibited stress induced changes of neurotransmitter content in brain.

  • Ginseng effectively regulates the immune response and the hormonal changes due to stress, thus maintaining homeostasis. In addition to suppressing the occurrence of psychological diseases such as anxiety and depression, ginseng also prevents stress-associated physiological diseases. Recent findings have revealed that ginseng is involved in adjusting the hypothalamic-pituitary-adrenal axis and controlling hormones, thus producing beneficial effects on the heart and brain, and in cases of bone diseases, as well as alleviating erectile dysfunction. Recent studies have highlighted the potential use of ginseng in the prevention and treatment of chronic inflammatory diseases such as diabetes, rheumatoid arthritis, and allergic asthma. However, the mechanism underlying the effects of ginseng on these stress-related diseases has not been completely established. In this review, we focus on the disease pathways caused by stress in order to determine how ginseng acts to improve health. Central to our discussion is how this effective and stable therapeutic agent alleviates the anxiety and depression caused by stress and ameliorates inflammatory diseases.

  • 스트레스에 대한 연구결과를 보면 대학생들은 학업과 사회관계 그리고 경제적 의존 등으로 인하여 매우 심각한 스트레스를 받고 있는 것으로 나타난다. 본 연구의 목적은 스트레스 저하이론과 집중력 회복 이론에 근거하여 대학생들의 스트레스와 인지수행에 미치는 자연경관의 영향을 조사하는 것이다. 이를 위해서 피부돌출도(GSR: galvanic skin responsse), 심박시간(IBI: interveat interval), 심리측정(ZIPERS: Zucherman Inventory of Personal Reactions), 그리고 산수암산이 평가도구로 채용되었다. 자연경관의 치유효과는 도시경관과의 비교를 통해 조사되었으며, 128명의 대학생이 연구에 참여하였다. 결과분석에는 120명의 자료가 이용되었다. 연구결과를 보면 심리적 스트레스 해소와 인지향상에서 자연경관의 치유효과가 도시경관보다 더 크게 나타나고 있는데, 이러한 결과는 자연경관의 치유효과를 입증하고 있다. 따라서 자연경관은 학생들의 스트레스 해소와 인지향상에 기여할 것으로 기대된다. 그러나 이러한 효과는 GSR과 IBI를 포함한 두 가지 생리측정에서는 발견되지 않았다. 더 나아가 IBI 측정결과를 보면 도시경관의 치유효과가 자연경관보다 높은 것으로 나타나고 있는데, 이러한 결과는 연구 참여자 특성과 연구대상 경관에 기인하는 것으로 생각된다. 구체적으로 연구 참여자의 나이가 젊고(평균 23.8세), 참여자가 다니는 대학교가 자연경관이 우세한 지역에 있다는 점이 생리측정 결과에 영향을 줄 수 있다. 또한 본 연구에서 사용된 도시경관이 Kaplan and Kaplan이 주장하는 네 가지 치유경관특질 중 하나인 공간감을 갖고 있는 점도 원인으로 생각될 수 있다. 이러한 논의에 근거하면 이후 연구에서는 경관의 내용과 종류 그리고 연구 참여자 특성이 자연경관의 치유효과에 미치는 영향을 밝히는 것이 필요할 것으로 판단된다.

  • Copper (Cu) is very toxic to plant cells due to its inhibitory effects on many physiological and biochemical processes. In spite of its potential physiological and economic significance, molecular characterization after Cu stress has so far been grossly overlooked in sorghum. To explore the molecular alterations that occur in response to copper stress, the present study was executed in ten-day-old Cu-exposed leaves of sorghum seedlings. The growth of shoots was markedly reduced, and ionic alterations were prominently observed in the leaves when the seedlings were exposed to different concentrations (0, 100, and $150{\mu}M$) of $CuSO_4$. Using two-dimensional gels with silver staining, 643 differentially expressed protein spots (${\geq}1.5-fold$) were identified as either significantly increased or reduced in abundance. Of these spots, a total of 24 protein spots (${\geq}1.5-fold$) from Cu-exposed sorghum leaves were successfully analyzed by MALDI-TOF-TOF mass spectrometry. Of the 24 differentially expressed proteins from Cu-exposed sorghum leaves, a total of 13 proteins were up-regulated, and 11 proteins were down-regulated. The abundance of most identified protein species, which function in carbohydrate metabolism, stress defense, and protein translation, was significantly enhanced, while that of another protein species involved in energy metabolism, photosynthesis and growth and development were severely reduced. The resulting differences in protein expression patterns together with related morpho-physiological processes suggested that these results could help to elucidate plant adaptation to Cu stress and provide insights into the molecular mechanisms of Cu responses in $C_4$ plants. The over-expression of GAPDH plays a significant role in assisting Sorghum bicolor to attenuate the adverse effects of oxidative stress caused by Cu, and the proteins involved in resistance to stress helped the sorghum plants to tolerate high levels of Cu.

  • 보리 유묘기의 수분스트레스가 생장 및 생리적 반응에 미치는 영향과 품종간 차이를 밝히고자 밀양 1002, 올보리, 두루보리, 백동 및 향맥을 공시하여 수행하였다. 공시종자를 폿트에 파종하여 발아 후 10일이 경과한 다음 단수처리를 10일간 한후 다시 관수하여 40시간 및 88시간에 초장, 건물 중, 엽록소함량 및 유리 proline함량을 조사하였다. 또한 발아 후 10일된 유묘를 P.E.G.로-20bar가 되도록 조정한 용액에 48시간 처리한 후 다시 재 관수하여 48시간 후에 엽록소함량, 잎의 수분포텐셜 및 유리 proline함량을 조사하였다. 1. 초장과 건물중은 10일간의 단수처리에 의하여 현저하게 감소하였는데 5 품종의 평균으로 보면 초장보다는 건물중의 감소가 심하였고, 백동과 향맥이 밀양 1002, 올보리 및 두루보리보다 감소 정도가 심하였다. 2. 엽록소함량 및 잎의 수분포텐셜은 10일간의 단수처리에 의하여 현저하게 감소하였으나, 재관수 후에 증가하는 경향을 보였으며, 유리 proline 함량은 단수처리 종료시에 함량이 증가하였다가 재 관수 후에 낮아지는 경향을 나타내었다. 생존율은 재 관수후 40시간에는 42%를, 88시간 후에는 14%를 나타내었다. 3. 단수처리에 의한 한해유발처리 종료시의 엽록소와 유리 proline 함량의 변화, 잎의 생존율 및 건물중 감소율을 근거로 한 품종들의 내한성을 보면 공시품종내에서는 겉보리(밀양 1002, 올보리, 두루보리)>쌀보리(백동)>맥주보리(향맥)의 순이었으며, 겉보리 품종간에는 뚜렷한 차이가 없었다. 4. P.E.G. 용액 (Ψ$\pi$=-20bar)으로 조정 한 48시간의 한해유발처리의 결과는 엽록소함량, 일의 수분포텐셜 및 유리 proline함량 모두 10일간단수처리 한 결과와 일양성을 나타내었다. 품종간에는 백동과 향맥이 수분스트레스시의 증가 및 관수시의 멸소반응이 모두 둔하여 수분환경적응성이 낮은 경향이었다.
