아토피 피부염은 만성 염증을 동반한 알레르기성 질환 이며, 일반적으로 Type 2 염증 반응과 관련이 깊다고 알 려져 있다. Corchorus olitorius (C. olitorius)의 아토피 피 부염 치료 효과를 확인하기 위하여 2,4-dinitrochlorbenzene 로 아토피 피부염 모델을 유도한 BALB/c 마우스를 대상 으로 피부 염증 개선도를 육안으로 확인하였으며, 질환 관 련 IgE와 사이토카인(IL-4, IFN-γ and TNF-α)의 수준을 측정 하였다. 7일간의 투여기간동안 양성대조약물인 Dexamethasone 투여군의 체중은 감소하였던 반면에 모든 C. olitorius 투 여군의 체중은 꾸준히 증가하였다. 이와 같은 결과는 C. olitorius이 동물에 위해한 영향이 없었다는 것을 의미한다. C. olitorius 200 mg/kg/day 투여군의 치료 효과가 가장 뛰 어났으며, 모든 C. olitorius 투여군의 염증 관련 면역글로 불린과 사이토카인의 수준은 감소하였다. 따라서, C. olitorius 는 아토피 치료제로 충분히 활용될 수 있다고 판단된다.

This study is aimed comparative analysis for business performance of land-based ezo abalone (Haliotis discus hannai) seed farms by standardizing cost structures by region and farming size. The result of survey on average farming incomes by region showed that farming incomes in Haenam and Jindo regions were much higher than those in other regions. Followed by Wando region, incomes in other regions were analyzed to be relatively lower. It is shown that farming incomes became higher as farm size increased. Farming incomes per unit size which were modified from farming incomes by region were highest in Jindo region, followed by East sea region, Wando and Haenam regions. Incomes in Jeju and Yeosu regions were analyzed to be relatively lower. Results on farming incomes per unit size (m2) showed that both farming incomes and profits became higher as size increased. It implies that a scale effectiveness might exist in case of land-based abalone culture system. Impacts of major factors on farming profits and returns on investment in abalone seed aquaculture are summarized as follow. First, only if the survival rate increased by 10% with improvement of component ratio, variable effects became largest. In variable effects of other factors, a variation in Jindo region was largest and on the other hand, a variation in Yeosu region was shown to be smallest.
