As people seek a healthy, wealthy, and quality life more than before, interests in mineral water are picking up and the consumption continues to increase accordingly. In an experiment to examine changes in the water quality after mineral water on the market was kept indoor and outdoor for four weeks, there seemed to be no problem in external appearance. Water kept in an outdoor storage contained more odor-savor than water kept in an indoor storage. Odor was not detected in 90% of the sample, and savor not in 80% of it. As for the mechanism of odor-savor generation, the elution of chemical substances from a container may be taken into consideration. In general, odor and savor have turned out to be in close correlation to each other. The average number of bacteria in the sample mineral water was 200±10 CFU/mL, and such factors as area of storage and ozone post-treatment did not cause significant effects on the reproduction of common microbes. Hence, it is thought that strict regulations on a production process and reduction of the period of circulation will contribute to customers consumption rates.

리소솜 acid phosphatase(LAP)를 포함하는 리소솜 산성 가수 분해 효소는 세포 내,외 성분의 분해에 중요한 기능을 수행하며, 유미 양서류의 다리 재생 과정에서 LAP의 효소 활성도는 탈분화시기에 특이적으로 증가하는 것으로 알려져 있다. 본 연구에서는 멕시코산 도룡뇽의 일종인 axolotl(Ambystoma mexicanum)의 다리 재생 가정에서 정상적인 다리 재생 조직과 retinoic acid (RA)가 처리된 다리 재생 조직에서 LA
