To determine the toxic effects of the mirror carp, Cyprinus carpio nudus on waterborne nitric acid exposure, they were exposed to waterborne nitric acid at 0, 4, 20, 100, 500, and 2,500 mg NO₃^-/L for 96 h. The semi-lethal concentration (LC₅₀) of the scented fish by 96 hours of acute exposure to nitric acid was 1,433.54 mg NO₃^-/L. The physiological changes of waterborne nitric acid exposure on mirror carp were evaluated through hematologic properties, and RBC count showed a significantly decreased (p < 0.05). The change in the ion control ability of the mirror carp according to exposure to waterborne nitric acid was evaluated through the plasma inorganic component, and calcium and magnesium were significantly decreased (p < 0.05) in the plasma inorganic component. The health and stress status of the mirror carp due to exposure to waterborne nitric acid were evaluated through plasma organic ingredients, and the plasma organic component glucose showed a significantly increase (p < 0.05). Changes in liver damage and enzyme activity due to waterborne nitric acid exposure were evaluated through plasma enzyme components, the enzymatic activities of plasma AST, ALT, and ALP were significantly decreased (p < 0.05) in high levels of waterborne nitric acid exposure. The results of the present study suggest that waterborne nitric acid exposure to C. carpio nudus can toxicly affect survival, hematologic properties, and plasma components.

넙치 치어에 대한 Naphthalene의 급성독성을 조사하기 위하여 대조구($0{\mu}g/\ell$), 1000, 1800, 3200, 5200, $10000{\mu}g/\ell$의 6개의 Naphthalene 농도구를 실정하여 24시간 동안 노출험을 실시하고 혈액학적 성상을 분석하였다. 넙치치어에 대한 Naphthalene의 24h-$LC_{50}$은 $2346.19{\mu}g/\ell$를 나타냈다. 넙치의 혈액학적 반응에서 헤마토크리트값은 5600, $10000{\mu}g/\ell$의 농도에서 대조구와 비교하여 유의하게 증가하였고, 글루코스는 $10000{\mu}g/\ell$의 농도에서 유의하게 증가 하였다. 삼투압 농토는 3200, 5600, $10000{\mu}g/\ell$의 농노 구에서 유의하게 증가하였다. 반면, 이온 분석 결과 $Na^+$, $K^+$은 5600 및 $10000{\mu}g/\ell$ Naphthalene 농도구에서 유의하게 증가하였으나 $Cl^-$는 큰 차이를 보이지 않았다.

본 실험 은 한방에서 특히 산모의 산후 회복에 효과적 이라고 알려진 호박이 산욕기 산모의 혈액성상 회복에 어떤 영향을 주는지 알아보기 위해서 진행되었다. 호박을 주원료로 8가지 한방 생약재를 첨가하여 압출액을 만든 후분만 직후의 산모 50명 에 게 21일간 복용시키고 혈액을 채취하여 적혈구와 hemoglobin을 복용전과 비교하였으며 또 호박 및 한방 생 약재를 복용하지 않은 대조군과도 비교 하였다. 본 실험 의 결과 적혈구 수치 는 분만직후의 3.65 $\times$$10^{6}$/mm에 서 4.6$\times$$10^{6}$/mm로 증가하여 3.9$\times$$10^{6}$/mm인 대조구에 비하여 높은 증가효과를 보여주었으며 정상적인 적혈구 범 위 에 드는 결과를 보여주었다. Hemoglobin의 경우도 분만 직후 10.35 g/dL에서 복용 21일 만에 12.61 g/dL로 증가하여 대조군인 10.88 g/dL과 비교하였을 때 유의적인 증가효과를 보여주었다 Hemoglobin수치 역시 임신 초기의 평균적인 수준을 초과하였으며 정상의 범위에 속하는 수준으로 회복하는 결과였다. 이후 적혈구와 hemeglobin 뿐 아니라 좀더 자세한 혈액성상을 연구할 과제가 있으나 본 연구의 결과 호박을 주원료로 한 한방 생약재 추출액은 분만 직후 산모의 적혈구 수치 및 hemoglobin의 회복에 효과적이라고 생각된다.

MPT 관리는 젖소, 육우의 혈액 성상을 판독해 영양대사 장애의 원인을 발견하고 그 대책을 종합적으로 조언해주는 서비스이다. 이를 잘 활용하면 젖소의 경제수명을 최대한 늘려주고 영양장애로부터 유발되는 각종 질병치료비도 절감시켜주는 등 경제효과가 크다. 다만, 소기의 효과를 거두기 위해서는 낙농비육농가와 MPT전문가와의 유기적인 협조가 중요하다.

To minimize the damage caused by summer season such as high temperature and red tide, this study was conducted to investigate the effect of feeding and starvation on the survival rate, growth, growth restoration and physiological response of red seabream Pagrus major which were reared in marine net cage ($6m{\times}6m{\times}6m$). The feeding group was fed throughout the experiment for 10 weeks, whereas starvation group was not fed for 6 weeks and subsequent refeeding for 4 weeks. Survival rates of feeding and starvation groups were 94.4% and 98.1% respectively. The growth rate of starvation group was significantly lower than feeding group during starvation period, but recovered rapidly after feeding. The nutritional status such as albumin, total protein, total cholesterol, triglyceride also showed similar tendency to the growth data. Hematocrit and hemoglobin levels were higher in the feeding group than the starvation group during starvation period. Aspartate aminotransferase, glucose and total cholesterol were rapidly increased at the same time (in 5 week) in feeding group, whereas starvation group did not significant difference during starvation period. It was shown that the feeding group is more sensitive to stress than the starvation group. Thus, starvation can be applied as a rearing management plan of net cage fish farm in summer season.
