Background The function of the p53 protein was known to regulate cell proliferation by inhibiting cells entering Sphase. So DNA damaged cell proliferation was inhibited by apoptosis. P21 is a cyclin dependent kinase inhibitor induced by wild type p53, not mutant p53. Thus p21 is thought go mediate the signal of p53 induced by DNA damaged agents to arrest the cell cycle in G1 phase. p53 and p21 were expressed in many malignant tumors, and its role in oncogenesis, tumor progression and prognosis were important. The authors analyzed immunohistochemical expression of mutant p53 and p21 protein in some skin tumors. Method Thirteen cases of actinic keratosis, 7 cases of keratoacanthoma and 8 cases of Bowen's disease were immunohistochemically stained with p53 and p21 monoclonal antibodies. Results; 1. In cases of positive p53 protein and negative p21 protein, the expressed p53 protein was suggested as mutant form. 2. Positive expression of p53 protein and p21 protein in prickle cell layer of actinic keratosis and Bowen's disease was suggesded that the composing cells of prickle cell layer were transformed into the proliferated cell. The p21 protein expression was suggested to be induced by the p53 independent pathway. 3. Negative expression of p53 protein and p21 protein in prickle cell layer of keratoacanthoma was suggested that the composing cells of prickle cell layer were completely mature cells, so the keratoacanthoma had good prognosis.

However, Endoscopic retrograde cholangiopancreatography (ERCP) is still helpful procedure for the diagonosis of the pancreatobiliary disease and treatment through endoscopic sphinterectomy (EST) is relatively safe, these have possiblity of complications such as hemorrhage, infection, panceatitis, and perforation. ERCP related perforation was rarely reported in 0.3 to 1.1% of previous study, but most serious complication. A report of Pneumomediastinum, Tension Pneumothorax complicating perforation after ERCP and EST is very uncommon. In our hospital, we experienced case of pneumomediastinum, subcutaneous emphysema, and tension pneumothorax after ERCP and EST, and the patient (a 58 years old female with suspicious common bile duct stone) was treated successfully with conservative treatment.

The second generation DS alloy CM186LC has comparable creep-rupture life to first generation single crystal alloys CMSX-2 and CMSX-3 in the as-cast and double aged condition. In the assembly of nozzle guide vanes, Ds components are joined into pairs by brazing. In order to study mechanical behavior of the material at the same condition as production, DS bars were subjected to brazing simulated treatments. Compared with standard treatment a small drop in creep-rupture life was observed but the degree of fall in life was not serious. Creep cracks initiated at the transverse components of the grain boundaries, which were normal to the applied stress direction. Every crack was associated with the v-v' eutectic phase at grain boundaries v-v' eutectic was not only located at grain boundaries but also in the interdendritic regions. It also acted as crack initiation site during creep. Low cycle fatigue tests were conducted under fully reversed trapezoidal strain wave at a frequency of 0.25Hz. The depth of the LCF cracks at the surface was comparable to that of the secondary dendrite arms from the surf-ace of the specimen. Cracks initiated at all of the interdendritic regions exposed at the surface, especially at the v-v' eutectic phase. LCF crack initiation and propagation are therefore proposed to be microstructally dependent.

The major characteristics of the developed corn hybrids were compared at each different planting time; 1st time(April 28) and 2nd time(August 20), respectively. Among traits surveyed, stem height showed highly at 1st time than 2nd, while ear height, stem diameter and ear length were similar at two times. Sugar content of the used hybrids showed highly at 2nd planting time than 1st. Pericarp thickness was also high at 2nd planting time. Especially, among hybrids CNU99 was the highest in stem height and ear length, CNU11 and CNU56 were high in sugar content, and CNU51 and CNU124 were thiner than other hybrids in pericarp thickness. Accordingly, these hybrids will be planted and recognized in 2nd yield trial for superior corn hybrid selection.

靈芝載培에 있어서 一般的인 栽培法을 改善하여 靈芝의 收穫量을 높이고 品質向上을 시킬 目的으로 菌絲의 活着條件, 種菌接種 時期 및 方法, 버섯培養地의 土養種類 등을 달리하고, 栽培舍 構造設備을 改良하여 靈芝를 栽培한 結果는 다음과 같다. 種菌接種短木에 菌接種時期가 1月, 12月, 2月, 3月, 4月, 順으로 氣溫이 올라 갈수록 菌絲活着 期間이 빨라져 버섯培養할 때 까지의 菌絲培養 期間을 10日 以上 短縮할 수 있었다. 菌絲培養床의 크기 中 菌絲培養床 幅을 各各 0.8m,1.2m로 하였을 때 같은 菌絲培養期間 동안의 菌絲活着率은 89.6%, 96.4%, 91.2%가 되어 菌絲培養床 幅이 1.0m에서 菌絲活着率이 가장 높았다. 接種短木에 種菌을 接種 後 密封方法은 스치로폴을 막은 後 파라핀으로 密封한 것이 菌絲培養條件에 關係없이 푸른곰팡이 發生率이 가장 낮았고, 스치로폴만 막은것도 新聞紙를 材料로 菌絲培養 條件을 改善하여 푸른곰팡이의 發生率을 파라핀으로 完全히 密封 것과 거의 같은 水準으로 抑制 시킬 수 있었다. 二重 비닐하우스 栽培舍內의 內部 하우스에 遮光幕을 設置함으로서 一般 裁培舍 하우스의 6個月 水準의 靈芝生育 適溫期間을 8個月 以上 까지 延長할 수 있었고, 收穫回數를 年 2回에서 4回로 늘릴 수 있었다. 內部 하우스에 遮光幕을 設置하여 改善한 栽培舍에서는 버섯培養 後 2年次에 目標水準 收穫量의 96.9% 까지 收穫할 수 있었는데 一般 栽培舍에서는 目標 收量의 89.1%만 收穫할 수 있었다. 收穫量에서도 改良 栽培舍의 上品靈芝收量이 一般 載培舍에 比하여 1.5倍의 增收를 보였다. 粘土含量이 가장 많고 모래 含量이 적은 E 土壤에서 雜菌發生이 가장 甚하여 靈芝의 收穫量 및 品質이 가장 低調하였다. To increase the yield and to obtain much better the quality on grown Ganoderma lucidum cultured, these experiments were conducted under carefully controlled in greenhouse with the following conditions on spawn spread related with tentative planting time of short timber inoculated, sealing methods with styrofoam only used and with sealing wax after styrofoam used, soil textures of planting sites, temperatures and growing time as the outside shield was commonly culture method and the inside shield was one of the methods improved itself in these experiments with double vivyl greenhouse. The results were as follow: Speeds of spawn spreading on inoculating Ganoderma lucidum to the short timber were faster when the temperatures were increasing as Jan.<Dec.<Feb.<Mar.<Apr., and it could be short more than 10 days for tentative planting time with inoculation. During the same time of tentative planting the rate of spawn was the highest at the width of 1.0m when the widths of tentative planting hotbets were 0.8, 1.0, and 1.2m, and the rates were 89.6, 96.4, 91.2%, respectively. Occurrences of green mold on inoculated timbers were the lowest as the sealing wax after styrofoam used without the conditions of tentative planting, and when there were surrounding the pile of timbers with styrofoam only used to seal inoculating holes with the second hand newspapers, those were almost the same level as the sealing wax after styrofoam used. When the shield over the roof of the inside greenhouse in the double greenhouse was set, the time on growing could be prolonged until more than 8 months and the yield could be increased 2 times more from 2 to 4 times as compared with the outside shielding over the vinyl that was the common culture method to be known. The culture with inside shielding could improve to be possible that the 96.9% of objective yield was done during two years only and that the amount of the best qualities was 1.5 times than in the common culture, the outside shielding, there was 89.1% of yield only at the same time. In sandy caly that was the least sand and was the most clay of the soils experimented there was the least of yield, there were the plenty of various germs occurred and there was not good in the quality.

농산물의 갈무리시 발생되는 건조한 마늘, 쪽파 및 대파 뿌리 분말을 흡착제로 이용하여 수용액 중 이온 상태로 존재하는 Ni과 Pb의 흡착력을 시료의 입자별, 중금속의 농도별, 용액의 온도별, pH별로 분석하였다. 중금속 이온들은 흡착제의 입자크기가 작을수록 흡착률이 높았고, 그중 마늘뿌리가 Pb에 대해 높은 흡착력을 나타냈다. 수용액중 중금속 농도가 높을수록 중금속들이 흡착되는 양이 증가하였고, 흡착률은 흡착제와 중금속의 종류에 따라 차이가 있었다. 온도의 증가는 쪽파와 대파에서 Ni과 Pb가 감소되었다. 알칼리 조건에서 비교적 흡착이 잘 되는 중금속은 Ni이며, 중성과 산성조건에서는 Pb의 흡착량이 높았다. A batch experiment was conducted to evaluate the removal capacity of welsh onion(Allium fistulosum L.), shallot(Allium ascalonicum L.), garlic(Allium sativum L.) roots as an adsorbent for Ni and Pb in aqueous solution. One gram of the dried Allium root powder was reacted in 100ml of solution containing 10㎎ of each heavy metal and effects of metal concentration, pH, temperature, and size of adsorbent on the removal efficiency were evaluated. The results were as follows : The amount of adsorption of heavy metal ions were higher with the smaller particles size of adsorbent. Garlic root was high adsorption capacity of Pb, especially. The higher concentration of heavy metal solution was, the more amount of adsorption of heavy metals was. The adsorption ratio was differed from a kind of heavy metal. As the temperature increased, the amount of adsorption of Ni and Pb by shallot and welsh onion were decreased. The amount of adsorption of Ni was high under alkali conditions but the amount of adsorption of Pb was high under neutral and acidity condition.
