  • In this experiment, interactions between light and other factors such as chilling, alternating temperature, moisture, content, oxygen, and seed coat which affect germination of Oenothera lamarckiana Ser. seed were investigated to study the physiological effects of light on the germination. Light induced the initial stage of seed germination before radical protrusion by affecting embryo rather than seed coat even under anaerobic condition or low water potential (-18 bars). This light effect on germinability of seed was suppressed by blue light irradiation and the effect was increased with increment of blue light intensity and irradiation time. However, the blue light effect was reversible. Chilling, alternating temperature, softening of seed coat and light showed promotive interaction in the induction of seed germination. Irradiation of filtered light (monochrome), however, reduced chilling effect on germination. Hydrogen-ion concentration and gibberellic acid treatment had no effect on light or dark germination.

  • In this study, we investigated the limit temperature range which is effective for dormancy release of 'Hongro' and 'Fuji' apples during the endodormancy period. The germination rate was 50% or more in all treatments except of 'Hongro' $-5^{\circ}C$ treatment. The germination rate of 'Fuji' was 86.3% at the temperature of $-5^{\circ}C$. The concentrations of carbohydrate and mineral components were significantly different between treatments but did not show any tendency or specific change. However, the sorbitol contents of 'Hongro' $-5^{\circ}C$ treatment were higher at 29.62 mg/g than those of 'Fuji', which was not affected for dormancy release. The results of hormone analysis showed that ABA(abscisic acid) and JA(jasmonic acid) in 'Hongro' $-5^{\circ}C$ treatment were respectively 176.48 and 15.72 ng/g. ABA, JA and SA(salicylic acid) contents in 'Fuji' apple tree were significantly lower than those of 'Hongro'. As a result of this study, the limit temperature range effective for dormancy release was different according to the varieties, and 'Hongro' did not affect with 30.3% of germination rate at $-5^{\circ}C$. However, 'Fuji' is 86.3% even at $-5^{\circ}C$ it was suggested that 'Fuji' had a chilling accumulation for dormancy release.

  • 최근 자연생태계에서 일어나고 있는 자생 민들레류의 감소와 서양민들레의 급속한 증가원을 종자 발아특성을 통해 알아보고자 한다. 각각의 종자는 무처리를 비롯하여 10일, 20일, 30일, 60일간의 저온처리를 실시하였으며 발아조건은 광조건과 암조건으로 실험하였다. 자생민들레의 경우에 광조건하의 무처리 대조구에서 28%의 발아율을 나타내었으나 60일간의 저온처리구에서 90%의 발아율을 나타내었다. 발아세와 평균발아기간도 30일 이상의 저온처리와 광조건하에서 양호한 성적을 나타내었다. 좀민들레의 경우에도 민들레와 거의 유사한 경향을 나타내어 30일 이상의 저온저리와 광조건하의 발아상태가 대조구에 비해 상대적으로 양호하였다. 그러나 서양민들레는 저온무처리구의 광조건에서 발아율 88.8%로 자생 민들레류에 비해 현저히 높게 나타났다. 또한 서양민들레 종자는 저온처리에 의핸 현저한 발아율 향상을 볼 수 없었다. 그러므로 30일 이상의 저온처리에 의해 휴면이 타파되고 발아율이 향상되는 자생 민들레류의 비휴면성인 성양민들에 비해 종 번식에 있어 상대적으로 불리하다는 것을 알 수 있었다.

  • We experienced an extremely rare case of lipoid pneumonia combined with empyema. A 53-year-old patient was admitted because of chilling sensation and blood tinged sputum. Simple X-ray and computered tomography(CT) showed a huge homogeneous opacification in the left lower lung field. This patient was diagnosed as endogenous type lipoid pneumonia by a computed tomography guided needle biopsy; decortication and left lower lobectomy are performed. We diagnosed it as endogenous type lipoid pneumonia because it revealed a foreign body reaction and lipid laden macrophage on the pathologic examination.

  • We report a 29-year old female who developed bilateral femoral neuropathy combined with multiple abscesses in both thigh muscles. She was present with weakness in both lower extremities for 15 days and intermittent chilling sense for 3 months. Nerve conduction study showed complete absence of compound muscle action potentials in bilateral femoral nerves when stimulated at inguinal area. Electromyographic examination revealed no motor unit action potentials in both rectus femoris and vastus medialis muscles. CT revealed multifocal abscesses in bilateral thigh muscles. After antibiotic treatment, the patient's neurologic symptoms were improved.

  • This experiment was carried out to investigate the appropriate chilling requirements for breaking dormancy by treating the dormant plant of Hanabusaya asiatica with low temperature ($4^{\circ}C$) for different time periods. The rates of sprouting and flowering were higher with longer treatment periods at low temperature. In addition, the growth and flowering of the plant were better when it was potted after treatment at a low temperature for 90 days. The abscisic acid levels and polyphenoloxidase activity of the dormant plant increased during the low temperature treatment, reached a climax 90 days and decreased thereafter. The catalase activity was the lowest after the low temperature treatment for 90 days and increased subsequently. The peroxidase activity increased and showed a sharp rise after the low temperature treatment for more than 90 days. Considering the physiological activities of the enzymes, the changes in the abscisic acid levels, and the characteristics of growth and flowering after sprouting of the plant, the appropriate cold periods required for breaking dormancy could be 90 days.

  • Objectives: The purpose of this study is to report the effects of Korean medical treatment including Sanhuhyulpung-tang on three postpartum patients who suffered from hyperhidrosis. Methods: We treated three patients complained of postpartum symptoms including hyperhidrosis. The patients were treated by Traditional Korean Medicine including herbal medicine, acupuncture, moxibustion, and cupping therapy. Sanhuhyulpung-tang is a herbal medicine prescription which is used in clinical practice for the treatment of postpartum sweating, anxiety, flushing, and joint pain. Three patients were hospitalized for treatment for 6, 8, and 19 days respectively. During hospitalization, patients took Sanhuhyulpung-tang three times a day, and acupuncture, moxibustion, and cupping were performed once a day. To evaluate the degree of improvement, we used VAS score of the patient's chief complaint during hospitalization. Results: After the treatment, symptoms including hyperhidrosis were improved. The degree of excessive sweating decreased to 30% in two patients, and 55% in one patient. Combined symptoms including lower coldness, burning sensation, chilling, and multiple site pain also improved on discharge day. Conclusions: This case report shows that Korean medicine treatment including Sanhuhyulpung-tang can improve postpartum symptoms including hyperhidrosis.

  • Chamaecyparis obtusa is one of the economical conifers planted in Korea due to its good quality timber and wood characteristics. Individuals of C. obtusa containing high terpenes (HT) and low terpenes (LT) were selected for by colorimetric method. The HT of C. obtusa was delayed in wilting against various abiotic stresses compared to the LT plants. The HT group exposed to UV did not significant influence the chlorophyll content, and the chlorophyll value was higher in the HT group than the LT group. Also, chilling treatment (5℃) did not significant influence on the chlorophyll content. However treatment at -4℃ showed relatively low chlorophyll content in the LT group than the HT group. Plants exposure to high temperature was not a difference between the HT and the LT group. However, treatment at 38℃ influenced the chlorophyll content that was increased exposure time-dependently. In salt treatments, chlorophyll in the HT group was lower at high concentrations (300 and 500 mM) of NaCl. However, chlorophyll content increased to slightly in treatment time-dependently, which is 6.7% to 40%. H2O2 treatment has been a negative effect on the chlorophyll content in the HT group. All concentration of H2O2 decreased the chlorophyll content of 5% to 35%. Plants containing high terpenoids were resisted against some abiotic stress such as salt and H2O2. Our results implied that terpenoids could cause various abiotic stress resistance. These results could be utilized for efficient management and biomass production during forest silvicultures.
