The present study was conducted to characterize maternal antibody status which haemagglutination inhibition(HI) titers against canine parvovirus(CPV) in the 15 puppies delivered from 3 dams. The range of HI titers of 5 puppies delivered from a mother dog(A) with HI titer of 1 : 1,024 were 1 : 16~1 : 64 at 1 day old before suckling, 1 : 512~1 : 1,024 at 2 days old after suckling, 1 : 512~1 : 2,048 at 1 week old, 1 : 256~l : 1,024 at 2 weeks old, 1 : 128~l : 512 at 3 weeks old, 1 : 128~l : 256 at 4 weeks old, 1 : 32~1 : 128 at 5 weeks old, 1 : 16~1 : 64 at 6 weeks old, 1 : 16~1 : 64 at 7 weeks old, and 1 : 16~l : 32 at 8 weeks old. After vaccination with DHPPL to canine parvovirus in 60 days and 80 days old puppies, 1 : 8~l : 32 at 9 weeks old, 1 :16~1 : 128 at 10 weeks old, 1 : 32~1 : 256 at 11 weeks old, 1 : 16~1 : 256 at 12 weeks old, 1 : 128~1 : 256 at 13 weeks old, 1 : 64~l : 512 at 14 weeks old, and 1 : 128~1 : 512 at 15 weeks old. The HI titers of 3 puppies delivered from a mother dog(B) with HI titer of 1 : 512 were 1 : 16 at 1 day old before suckling, 1 : 256~1 : 512 at 2 days old after suckling, 1 : 512 at 1 week old, 1 : 128~1 : 256 at 2 weeks old, 1 : 64~1 : 128 at 3 weeks old, 1 : 64~1 : 128 at 4 weeks old, 1 : 128 at 5 weeks old, 1 : 64~1 : 128 at 6 weeks old, 1 : 16 at 7 weeks old, and 1 : 8 at 8 weeks old. After vaccination with DHPPL to canine parvovirus in 60 day and 80 days old puppies, < : 8~l : 8 at 9 weeks old, < : 8 ~1 : 16 at 10 weeksold, 1 : 64~1 : 128 at 11 weeks old, and 1 : 256~1 : 512 at 12 weeks old. The HI titers of 7 puppies delivered from mother dog(C) with Hl titer 1 : 1,024 were 1 : 512~1 : 1,024 at 2 days old after suckling, 1 : 256~1 : 1,024 at 1 week old, 1 : 256~l : 1,024 at 2 weeks old, 1 : 64~1 : 512 at 3 weeks old, 1 : 64~1 : 512 at 4weeks old, 1 : 8~l : 64 at 5 weeks old, 1 : 8~1 : 64 at 6weeks old, 1 : 8~1 : 32 at 7 weeks old, and < : 8~1 : 8 at 8 weeks old. Antibody to CPV was transferred mainly from mother to progeny through the colostrum and the transferred maternal antibody was in proportion to the HI titer of the mother As the HI titer of maternal antibody in puppies was low, puppies have a rapid immune response and a massive rise in HI titer to vaccination against CPV compared with puppies haying high level of maternal antibody.

The extent of water pollution was investigated at 4 stations in Kyonggi Bay during the summer seasons in 1970 and 1971. The concentrations of dissolved oxygen, total hardness, ammonia, nitrate, nitrite, phosphate, chemical oxygen demand, salinity, biochemical oxygen demand, coliform bacteria and facel coli were examined together with the measurement of pH and transparency. The relationship between the extent of pollution and the distance from the Inchon Bay also was examined. The concentrations of biochemical oxygen demand, chemical oxygen demand, ammonia, nitrate, nitrite, phosphate, coliform bacteria nad fecal coli were all highest at station 1, and lowest at station 4. Values were somewhat higher at low tide level in general. On the contrary, dissolved oxygen concentration was highest at station 4 and lowest at station 1. The highest and lowest values of biochemical oxygen demand were 10.88 ppm at station 1 and 0.27 ppm at station 4. The chemical oxygen demand concentrations at station 1 and 4 were 1.90 ppm and 0.63 ppm. Ammonia concnetration at station 1 was 0.43 pp, and was nearly 5 times as much as that at station 4. The values were $2.45{\times}10^{-4}$ ppm at station 1, and $6{\times}10^{-4}$ ppm at station 4. Nitrite concnetration at station 1 was $3{\times}10^{-4}$ppm and was the highest, while the lowest was $9.45{\times}10^{-5}$ ppm at station 4. Phosphate value at station 1 too was the highest and was about 4 times as much as that at station 4. Coliform bacteria were most abundant at station 1, and were counted to be 1.$1.7{\times}10^{-5}$cells/ml. At station 4, the number greatly reduced to 8 * 10$^{2}$ cells/ml. The number of fecal coli at station 1 was $2{\times}10^{-4}$ cells/ml. But at station 4, no fecal coli was detected at high tide level. At low tide level, 3 cells/ml were counted at station 4. In all of these, the highest data were obtained at low tide level, while most of the lowest value, at high tide level. Generally, values at statio 1 were 3-5 times as much as those at station 4. Concentration of dissolved oxygen at station 1 was 0.366 mg-atoms/1 and was the lowest. The highest value was 0.420 mg-atoms/1 and was recorded at station 4. The highest at station 4, which certainly were believed to be the result of the dilution by the fresh water of the Han river flowing into the Inchon Bay. As we can see from the data above, the extent of pollution was highest at station 1, the nearest from Inchon harbor, and lowest at station 4, where is the farthest, Station 1 and 2 were proved to be much polluted, but station 3 and 4, not.

환경 스트레스는 식물의 성장을 저해하며 작물의 생산량을 감소시키는 주요 원인이다. 식물은 다양한 유전자의 발현 변화를 통해 스트레스에 대한 저항성을 나타낸다. 본 연구에서는 activation tagging system을 이용하여 기존에 밝혀지지 않은 새로운 고염 스트레스 반응 유전자들을 분리하였다. 애기장대의 발아 단계에서 고염 스트레스에 저항성을 보이는 9개의 activation tagging 라인을 선별하였다. 그 중 TAIL-PCR 방법을 이용하여 AT7508, AT7512, AT7527, AT7544, AT7548, AT7556의 6개 라인에서 T-DNA가 삽입된 위치를 확인하였으며 각 라인에서 T-DNA가 삽입된 주변 유전자의 발현을 RT-PCR로 분석하였는데 AT7508, AT7512, AT7527, AT7544, AT7556에서 각각 ClpC2/HSP93-III (At3g48870), plant thionin family (At2g20605), anti-muellerian hormone type-2 receptor (At3g50685), vacuolar iron transporter family protein (At4g27870), microtubule-associated protein (At5g16730)이 activation 된 것으로 밝혀졌다. 더불어 AT7548에서는 T-DNA가 삽입된 곳의 양쪽에 위치하는 두 유전자인 Arabinogalactan protein 13 (AGP13) (At4g26320)과 F-box/RNI-like/FBD-like domains-containing protein (At4g26340)이 모두 activation 되었다. Activation 된 7개 유전자는 기존에 고염 스트레스 저항성과 관련된 기능이 알려지지 않은 유전자로 본 연구를 통해 새롭게 고염 스트레스 반응에 대한 기능이 밝혀졌다. 7개의 activation된 유전자 중 ClpC2/HSP93-III, AGP13, F-box/RNI-like/FBD-like domains-containing protein의 3개 유전자는 고염 스트레스에 의해 발현이 증가하였다. 또한 AT7508과 AT7527, AT7544 라인은 발아 단계뿐만 아니라 유식물체 발달 과정에서도 고염 스트레스 저항성을 보여 activation tagging 라인의 선별 결과의 타당성을 뒷받침 하였다. 본 연구의 결과를 통해 activation tagging system이 새로운 스트레스 반응 유전자를 찾아낼 수 있는 유용한 기술임을 확인할 수 있었다.

Buckwheat protein isolate was tested for the effects of pH, addition of sodium chloride and heat treatment on solubility, emulsion capacities, emulsion stability, surface hydrophobicity, foam capacities and foam stability. The solubility of buckwheat protein isolate was affected by pH and showed the lowest value at pH 4.5, the isoelectric point of buckwheat protein isolate. The solubility significantly as the pH value reached closer to either ends of the pH, i.e., pH 1.0 and 11.0. The effects of NaCl concentration on solubility were as follows; at pH 2.0, the solubility significantly decreased when NaCl was added; at pH 4.5, it increased above 0.6 M; at pH 7.0 it increased; and at pH 9.0 it decreased. The solubility increased above $80^{\circ}C$, at all pH ranges. The emulsion capacity was the lowest at pH 4.5. It significantly increased as the pH approached higher acidic or alkalic regions. At pH 2.0, when NaCl was added, the emulsion capacity decreased, but it increased at pH 4.5 and showed the maximum value at pH 7.0 and 9.0 with 0.6 M and 0.8 M NaCl concentrations. Upon heating, the emulsion capacity decreased at acidic pH's but was maximised at pH 7.0 and 9.0 on $60^{\circ}C$ heat treatment. The emulsion stability was the lowest at pH 4.5 but increased with heat treatment. At acidic pH, the emulsion stability increased with the increase in NaCl concentration but decreased at pH 7.0 and 9.0. Generally, at other pH ranges, the emulsion stability was decreased with increased heating temperature. The surface hydrophobicity showed the highest value at pH 2.0 and the lowest value at pH 11.0. As NaCl concentrationed, the surface hydrophobicity decreased at acidic pH. The NaCl concentration had no significant effects on surface hydrophobicity at pH 7.0, 9.0 except for the highest value observed at 0.8 M and 0.4 M. At all pH ranges, the surface hydrophobicity was increased, when the temperature increased. The foam capacity decreased, with increased in pH value. At acidic pH, the foam capacity was decreased with the increased in NaCl concentration. The highest value was observed upon adding 0.2 M or 0.4 M NaCl at pH 7.0 and 9.0. Heat treatments of $60^{\circ}C$ and $40^{\circ}C$ showed the highest foam capacity values at pH 2.0 and 4.5, respectively. At pH 7.0 and 9.0, the foam capacity decreased with the increased in temperature. The foam stability was not significantly related to different pH values. The addition of 0.4 M NaCl at pH 2.0, 7.0 and 9.0 showed the highest stability and the addition of 1.0 M at pH 4.5 showed the lowest. The higher the heating temperature, the lower the foam stability at pH 2.0 and 9.0. However, the foam stability increased at pH 4.5 and 7.0 before reaching $80^{\circ}C$.
