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

We performed in vitro and in vivo studies to know whether the inhibitory effects of ginsenosides on $5-HT_{3A}$ receptor channel acctivity are coupled to anti-nausea and anti-vomiting action. In vitro study, we investigated the effect of compound K (CK) and M4, which are ginsenoside metab...

  • Voltage-independent inhibition of I5 HT by M4. A. The representative current-voltage relationship was obtained using voltage ramps from -100 and +60 mV of 300-ms duration. Vbltage steps were applied before and after application of 10 μM 5-HT in the presence or absence of 100 μM CK or M4.
  • The cells were pretreated with M4 for 30s before 5-HT was applied. C. Summary of CK- or M4- induced inhibition of I5 Hr Holding potential was -80 mV. Tracings are representative of results with eighteen separate oocytes from three different frogs.
  • 5 ㎎/㎏), we could observe cisplatin-induced emesis including nausea and vomiting"). As shown in Figures 5-7, cisplatin-induced nausea and vomiting episodes appeared after 60 min, reached to peak after 2 h, and persisted 니ntil 4 h. As a next step, we tested the effect of GTS on cisplatin-induced emesis. When we pre-administered GTS into cat with less than 250 ㎎/㎏ via oral route, we could not observe significant inhibitory effect of GTS on cisplatin (7.
  • ). Number of nausea and vomting in the cat induced by a single dose of cisplatin was counted every 30 min intervals during 4 h. Results represent the mean + S.E.M. (*p v 0.01 compared with saline treatment alone, n = 7 - 8).
  • ). Number of vomiting in the cat induced by a single dose of cisplatin was counted every 30 min intervals during 4 h. Results represent the mean ± S.E.M. (切 < 0.01 compared with saline treatment alone, n = 7 - 8).
