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

Objective : Minocycline, a second-generation tetracycline-class antibiotic, has been well established to exert a neuroprotective effect in animal models and neurodegenerative disease through the inhibition of microglia. Here, we investigated the effects of minocycline on motor recovery and neuropath...

제안 방법

  • Here, we examined the ability of minocycline to promote motor recovery and reduce neuropathic pain in a rat model of SCI. Additionally we also evaluated whether minocycline attenuates microglial and astrocyte activation post SCI.
  • number of experimental rats. Moreover, although we did not quantify the resulting lesion size secondary to SCI, we expect these measurements to be included in any subsequent investigations that quantify the extent of minocyclines neuroprotective effect. Despite these limitations, our results strongly suggest that minocycline exerts a significant neuroprotective effect after SCI, and may also promote post-SCI motor recovery
  • The locomotor activity of the rats was assessed via semiquantitative method both before the operation, and at 1, 2, 4, 7, 10, 14, 20 and 28 days after surgery; Testing was performed by two trained observers under blind conditions and using BBB scales. The BBB locomotor rating has previously been described qualitatively with a 21-point scale by Basso et al*.

대상 데이터

  • Fifteen male Sprague-Dawley rats (Orient Bio, Seoul, Korea) with body weights between 250-350 g were used. The rats were divided into three groups: sham control (n=5), hemisection control (n=5), and hemisection with minocycline (Hemi+Mino, n=5).
  • The animals were anesthetized with a mixture of Tiletamine+Zo-lazepam (27.78 ㎎/㎏) and Xylazine (0.647 ㎎/㎏), before being mounted on a frame. A 3 cm midline incision was made on the back so the deep back muscles could be retracted to expose the lower thoracic vertebrae.

데이터처리

  • Fifty percent probabilitythresholds of mechanical paw withdrawal were calculated75. Statistical analysis was performed by one-way ANOVA using SPSS (12.0 program).
