Background: In recent years, adjuvants have received increasing attention owing to the development of purified subunit and synthetic vaccines which are poor immunogens and require additional adjuvants to evoke an immune response. Therefore, immunologic adjuvants have been developed and tested. Plant polysaccharides have been recognized as effective biological response modifiers with low toxicity.Methods and Results: In this study, the polysaccharide from the aboveground part of Astragalus membranaceus Bunge containing immunomodulating arabino-3,6-galactan was evaluated for its hemolytic activity and adjuvant potential in the specific cellular and humoral immune responses to ovalbumin. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge was co-immunized with the purified Vi capsular polysaccharide of Salmonella typhi vaccine in mice. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge did not induce any hemolytic activity or side effects at doses up to 500㎍/㎖. The concanavalin A-, lipopolysaccharide-, and ovalbumin-induced splenocyte proliferation and serum ovalbumin-specific IgG, IgG1 and IgG2b antibody titers in immunized mice were significantly enhanced by AMA. Pharmacological data revealed that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge increased antigen-specific antibody levels in immunized mice. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge-adjuvanted purified Vi capsular polysaccharide of Salmonella typhi vaccine improved the proliferation of splenocytes and macrophages as well as stimulated cytokine production.Conclusions: These results suggest that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge-adjuvanted vaccines enhanced humoral and cellular immunity and that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge is a safe and efficacious adjuvant candidate suitable for use in prophylactic and therapeutic vaccines.

본 연구는 고강도 섬유보강 시멘트 복합체(UHSCC) 접착성능을 평가하는 것이 목적이다. Direct shear test를 통해 압축전단접착강 도를 측정한 결과 NC(보통강도콘크리트)+ NC 실험체(150×150×150)에서는 모든 수준에서 유사한 압축전당접착강도를 나타내었고, 반 면 UHSCC+UHSCC에서는 지연타설 30분 후부터 0분에 비해 압축전단접착강도가 낮아지는 것을 확인할 수 있었다. 이를 통한 접착면의 파괴 모드를 분석한 결과 NC+NC 에서는 모든 수준에서 비계면 파괴를 보였고 UHSCC+UHSCC에서는 30분, 60분, 90분 시험체에서 계면파괴가 일 어났다. NC 및 UHSCC의 타설면을 XRD 시험을 통해 분석한 결과 NC 시험체에 비해 UHSCC의 시험체 에서 많은량의 SiO2의 성분이 검출되 는 것을 알 수 있었고 UHSCC에서 나타난 코팅막의 주성분의 대부분은 SiO2로 사료된다. 따라서 본 연구에서 사용된 UHSCC는 지연타설 30분 후 부터는 접착성능의 저하로 구조체로서의 사용이 어렵다고 판단된다. 금후 연구에서는 콜드조인트 발생 부위의 면처리 방법을 통한 접착성 능 향상이 필요하다고 사료된다.
