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

This study examined whether or not acute stress is linked to increases in the neurosteroid levels, which is a well-known neurotransmitters associated with stress stimuli. The ginsenoside, Rb1, was tested in order to better understand its potential effects on altering the neurosteroid levels and ulti...

제안 방법

  • ethic시 committee of Ky나ng Hee University. The optim기 stressed condition was chosen by testing the versatile stress-duration time, 5, 30, 60, 120, and 240 min and 1, 3, and 7 days. The normal gerbil-mice were divided into 8 groups (n=4), and each group was stressed by immo- bilization in a tightly fitted, ventilated plastic bag.
  • , 2004; Ordyan and Pivina, 2003). Therefore, this study examined the brain neurosteroid level 니nderthe stressed condition in order to determine if the antistress effect of ginseng is related to the brain neurosteroid level.

대상 데이터

  • The concentration of neurosteroids in the brains of the stressed cont「이 g「。니p and Rb1- treated stressed gi■。니p was compared. The ginsenoside Rb1 was supplied by Kyung Hee University (Seo니I, Korea).
  • The supernatant of the brain homo­ genate was diluted with 5 mL of distilled water. The samples were extracted with OASIS HLB cartridges (60 mg, 3 mL; Waters), which were equipped in a vacuum m러iuf이der and equilibrated with MeOH (1 mL) prior to sample loading. The cartridge was washed with methanol/ H2O (5/95, v/v; 1 mL) s니ccessively.
