The purpose of this study was to characterise the subacute toxic potency of i.v. administered KHPC-005 and 006. Few test compounds-related toxic effects were observed in body weight gain, clinical signs, urinalysis, hematological parameters and serum biochemical values. Gross necropsy and histopathology revealed no evidance specific toxicity. Our data indicated that no-observed effect level of KI-IPC-005 and 006 were estimated to be 10mg/kg and 4mg/kg in male rats, and 10mg/kg and 1.33mg/kg in female rats, respectively.
새로운 항암성 백금(II) 착체류의 in vivo 독성 연구

The general toxicological study of new platinum(II) compounds, KHPC-002, KHPC-005 and KHPC-006 were investigated in rats. The effects of these Pt(II) complexes on renal, hematopoietic and hepatic system in rats showed lower toxicity compared with cisplatin. In the consideration of the maximal dose of these Pt(II) complexes using in this experiment is 4-8 times higher than cisplatin, these novel compounds will have the less general toxicity in vivo.
이득-투명 SOA 스위치를 이용한 광 ATM 셀 역압축기
정광원,안상호,이정렬,이승우,엄진섭 한국통신학회 2001 韓國通信學會論文誌 Vol.26 No.7
본 논문에서는 이득-투명 SOA 스위치를 이용한 새로운 구조의 광 셀 역압축기를 제안하였다. 제안된 구조는 하드웨어 및 제어의 단순화와 이득-투명 SOA를 이용함으로써 처리용량을 극대화하기 위한 요구조건을 만족시킨다. 제안된 구조의 동작을 실험으로 보이기 위해 4-비트의 소규모 광 압축셀을 역압축시키는 실험을 수행하였으며, 제안구조의 동작원리와 일치하는 결과를 얻을 수 있었다. 이는 시간분할 방식을 포함하는 광 ATM 교환기와 광 패킷망 등에 주요 요소로서 적용될 수 있다.
SOA내에서의 XPM,FWM을 이용한 WDM 시스템 파장변환기 구현

In this paper, a new type of wavelength converter using XPM within a loop-mirror is proposed and demonstrated. The proposed structure decreases hardware components for implementation of XPM wavelength converter and makes it possible to get non-inverted and inverted output signals simultaneously. Also, we generate wideband pumping mode series for FWM wavelength conversion scheme and propose the effective filtering method for selecting converted wavelength from FWM outputs. The results show that the pumping mode range is over 30nm within 5dB power fluctuation, and that a pumping and a prove wave can be removed successfully by using both of Michelson interferometer and polarization controller.
