To study the physiological adaptation(shift-up) of phytoplankton under the simulated upwelling conditions, nitrate uptake capacity of Dunaliella tertiolecta batch culture was measured in the laboratory using the stable isotope ^(15)N-KNO₃. Contrary to the expected, there was no significant relationship between the maximum V_(NO3) (nitrogen specific nitrate uptake rate) and the initial nitrate concentration. However, there was a strong relationship between the maximum ρ_(NO3) (nitrate transport rate) and the initial nitrate concentration of <25μM, which was also influenced by the physiological status of the culture. The increase In V_(NO3) was mainly due to the increase in PON (particulate organic nitrogen) concentration and partly due to the increase in V_(NO3). When the phytoplankton population was severely shifted-down, the physiological adaptation of nitrate uptake was significantly inhibited at high initial nitrate concentrations. The timing of the maximum V_(NO3) or ρ_(NO3) was related to the initial nitrate concentration. At higher initial nitrate concentrations, maxima in V_(NO3) and ρ_(NO3) occurred 1 or 2 days later than at lower nitrate concentrations. This relationship was the opposite to the prediction from the shift-up model of Zimmerman et al.(1987). The shift-up process is apparently controlled by an internal time sequence and the initial nitrate concentration, but the magnitude of V_(NO3) was affected little by changes in nitrate concentration.

대규모 연초건조장 부근의 뽕잎이 잠작에 미치는 영향을 알고자 무독상엽으로 인정되는 잠업시험장 (수원)의 유업을 대조로 하여 충남 논산군 논산읍 소재 연초건조장으로부터 30∼50m, 300∼400m 및 700∼800m 지점에 위치한 유전의 뽕을 채취하여 이를 소잠시부터 상족전까지 급여 시험한 결과를 분석하여 각각의 계량형질에 미친 영향을 요약하면 다음과 같다. 1. 누에 경과는 1령부터 3령까지는 대조와 같았으나 4령기부터 길어지기 시작하여 5령 및 전령에서 유의차가 있었다. 2. 숙잠발현기간은 대조구에 비하여 누에의 경과 및 발육이 고르지 못하여 건조장에 가까운 순으로 길었다. 3. 감잠비율은 장잠, 족중, 명중 공히 건조장에 가까운 처리구가 가장 높았고 특히 장잠 및 난중에서 심했다. 4. 화용비율은 근거리구가 가장 낮았고 중간 및 원거리구는 같은 수준으로 대조와 유의차가 없었다. 5. 전견중, 견증중은 각 처리구 공히 피해가 인정되었으며 대조구와 유의차가 있었고 견층비율은 대조에 비하여 각 구가 공히 같은 비율로 감소되어 유의차가 없었다. 6. 각견비율은 대조구의 상견비율 87.1%에 비하여 각 처리구간에 유의차가 있었으며 근거리구가 가장 고치가 고르지 못하고 중간거리구와 원거리구는 같은 수준이었다. 7. 수견량 (대 4령기잠 1만두 상견)에서는 연초건조장에서 가까운구가 대조구에 비하여 현저히 감수되었으며 중간 및 원거리구는 같은 수준으로 감수되어 고도의 유의차가 있었다. 이상을 종합하여 보면 충질, 견질 및 수견량에 피해를 주는 거리는 건조장과 유전의 위치 및 풍향 등에 따라 다르겠으나 본 시험에서는 800m까지도 피해가 있었다. 8. 본 시험은 Nicotine에 오염된 뽕을 채취하여 잠업시험장에서 누에를 사육한 관계로 누에가 오염된 뽕을 식하하므로 생기는 식중독만을 인정할 수 있다. 따라서 현지에서 누에를 사육할 경우에는 뽕 오염에 의한 식중독뿐만 아니라 연초건조장 부근의 오염된 공기가 누에의 피부에 접촉되어 발생하는 경피독 및 누에의 호흡시 기문을 통하여 일어나는 호흡 독에 의한 피해도 예상할 수가 있는 것이다. The objective of the present study was to investigate the effect of nicotine-contaminated mulberry-leaf, which was grown in the vicinity of tobacco drying plant (TDP), on cocoon crop. Mulberry-leaf harvested from the field at Sericultural Experiment Station (SES), Suweon, Korea, was used as control, supposedly nicotine-free leaf. Leaf harvested from the field in the distances of 30-50m, 300-400m and 700-800m from TDP was fed during the whole larval stage of the silkworm at SES. The effect of leaf in each treatment level on the quantitative characters of the silkworm was summarized as follows; 1. Larval duration from 4th instar on was significantly longer in the TDP-leaf treatments than for the control. 2. Duration of matured silkworm appearance became longer as the distance of the mulberry-field from TDP got shorter, because the larval duration and growth of the silkworm were not uniform in the TDP-leaf treatments. 3. Mortality rates during the late larval, cocoon spinning, and pupal stages were highest for the 30-50m leaf, especially mortality rates during the late larval and pupal stage were serious. 4. Pupation rate was lowest for the 30-50m leaf and those for the 300-400m and the 700-800m leaf were not significantly different from that of the control. 5. Nicotine damage to cocoon weight and cocoon shell weight was significant in each TDP-leaf level. Cocoon shell ratio was reduced at the same extent in each level, compared with the control. 6. The ratio among cocoon-classes was significantly different between treatments, compared with best-cocoon ratio of 87.1% for the control. Cocoons were not uniform for the 30-50m leaf, and those for the 300-400m and the 700-800m leaf were as almost uniform as those for the control. 7. Loss of fresh cocoon yield became greater as the distance of the mulberry-field from the TDP-got shorter. In conclusion, the critical distance of mulberry-field, which influences larval health, cocoon quality and yield, appeared to be 800m from the TDP. Such other factors as wind direction and topographic location may be involved in the critical distance. 8. From the present experiment, we could obtain only the effect of nicotine on the silkworm through digestive system, since the silkworm was raised at SES in Suweon. If the silkworm, were raised in the vicinity of the TDP, poison effect of nicotine on the silkworm could beo expected through exoskeleton and tracheal system as well as through digestive system.

Craniofacial reconstructive procedures are frequently peformed with rigid fixation of the bone. During the period of active bone growth such manipulation may influence bone development. The purpose of this study was to determine the effects of metal plating of the mandible on the growth and morphology of the mandibulofacial skeleton. New Zealand white rabbits, 6 to7 weeks of age, were divided into 5 groups. They were designated as group Ⅰ(nonoperated control, n=10), group Ⅱ (rigid fixation of mandibular body after vertical osteotomy, n=10), group Ⅲ(rigid fixation without osteotomy, n=10), group Ⅳ(interosseous wire fixation after osteotomy, n=10), and group Ⅴ(rigid fixation and removal of plates and screws 4 weeks after osteotomy, n=7). Rabbits were sacrificed 12 weeks after operation and dry skull preparations were grossly measured and analyzed by direct measurement and by dorsoventral skull x-rays. Measurements taken were length, thickness, angle, and area of the mandibulofacial skeleton. Three-dimensional CT was used for volumetric measurement of the mandible. The data wee compared between the operated and nonoperated sides and significant differences between groups were evaluated using the paired t-test, the ANOVA test, and Dunn's test. The following results were obtained: 1. The length of the whole mandible and the anterior mandibular segment was decreased in groups ⅡandⅢ, compared with group Ⅰ(p<0.05). These results show growth restriction of the plated mandible regardless of osteotomy. 2. The maxillary alveolus of the operated side was more anteriorly placed in groups Ⅱ and Ⅲ, compared with group Ⅰ (p<0.05). 3. The thickness of the operated mandibular body showed a significant increase in groups Ⅱ and Ⅲ, compared with group Ⅰ(p<0.05). 4. The length of the zygomatic arch of the operated side in all the experimental groups showed a significant decrease, compared with group Ⅰ(p<0.05). The angular divergence of the mandibular ramus from the sagittal midline of the skull was increased in the operated side of groups Ⅱand Ⅲ, compared with the nonoperated side (p<0.05). 5. Volume measurements of the mandible in groups ⅡandⅢ showed a significant reduction of the volume on the operated sides in the anterior mandibular segment, compared with group Ⅰ(p0.05). The volume of the operated mandibular body showed a significant increase in groups Ⅱ and Ⅲ, compared with group Ⅰ(p<0.05). All gruops showed no significant difference in total hemiman dibular volume of the operated side compared with the nonoperated side. These results show that rigid fixation of mandibular fractures during the growth period causes a more severe growth restriction than either osteotomy or interosseous wiring.
