연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

GATA-binding protein-3 (GATA-3) and T-box expressed in T-cells (T-bet) are now considered as master transcription factors involving Th cell differentiation, but the roles of these factors are still uncertain in vivo. This study was conducted to investigate the expression of these transcription facto...

문제 정의

  • 따라서 본 연구에서는 사염화탄소 투여로 유발된 흰쥐의 간 손상에 어떠한 면역조절 효과를 나타내는지 확인하고자 흰쥐에 황금 추출물을 투여하여 급성 장기 손상에서 단백질 발현을 확인함과 동시에 면역학적 변화를 관찰하였다.
  • 본 연구는 흰쥐에 황금 추출물을 4주간 투여하여 사염화탄소로 유발된 흰쥐에서의 면역 조절 효과를 확인하기 위해 수행되었으며, 간의 면역력을 증강시키는 물질을 찾기 위해 조직 중 liver에서의 면역학적인 효과를 보았다.

질의응답

핵심어 질문 논문에서 추출한 답변
사염화탄소에 관해 설명하시오. 사염화탄소 (carbon tetrachloride, CCl4)는 지방성 퇴행(fatty degeneration), 섬유증 (fibrosis), 간세포 사멸 및 발암 등을 유발시키며, 독성물질이 간세포에 미치는 영향과 그 대사과정을 규명하는데 대표물질로써 주로 사용되어 왔다(Weddle et al., 1976).
nitrite를 측정을 위해 사용한 방법은 어떤 특징을 이용한 것인가? CCl4에 의해 손상된 간과 면역기관으로부터 생성된 nitrite를 측정하기 위하여 griess 반응을 이용하였다. 이 방법은 griess 시약의 diazo기가 nitrite를 만나면 분홍색으로 변하게 되는 색의 반응을 이용한 것이다. 조직을 100 mM Tris-HCl buffer에 넣어 분쇄한 후, 원심분리하여 상층액을 얻었다.
면역 조절 기능성 성분으로 연구되고 있는 한약재 황금에 관해 설명하시오. 면역 조절 기능성 성분으로 연구되고 있는 한약재 황금은 꿀풀과에 속한 다년생 초본인 Scutellaria baicalensis Georgi의 주피를 벗긴 뿌리를 건조한 것으로 독성이 적고 주성분은 flavonoid계 화합물로서 30여종이 분리되어 있다 (Kim, 2001; Lim et al., 2007a).
