Abstract

Polyvinyl alcohol (PVA) resin has been generally used as a resin for embedding for cryomicrotomy for rapid histological analysis in the operating room. However, due to the lack of cohesion and penetration of resin, and the relatively high freezing point, and the difference in the mechanical properties of resin and tissue, there have been difficulties in obtaining satisfactory intercepts. In this study, a modified PVA-based embedding resin composed of PVA and boric acid, which can improve histological analysis efficiency, and NaOH as a crosslinking reaction catalyst was studied. It was confirmed that as the amount of PVA, boric acid, and NaOH increased, physical properties including cohesion were improved. And complete tissue cross-section could be obtained without damage using 10 wt% PVA, 2 wt% boric acid, and 0.3 wt% NaOH composition, and hematoxylin and eosin staining tests showed clear tissue images. The modified PVA-containing resin of this study is expected to improve the rapid histological analysis efficiency of various biological tissues.


폴리비닐알코올(PVA)계 수지는 수술장에서 신속한 조직 검사를 위한 동결 절편용 포매용 레진으로 널리 사용되어 왔다. 그러나 레진의 부족한 응집력과 침투력, 그리고 상대적으로 높은 어는점, 레진과 조직의 기계적 물성의 차이 때문에 만족스러운 절편을 얻는데 어려움이 있었다. 본 연구에서는 조직학적 분석 효율을 향상시킬 수 있는 PVA와 붕산, 그리고 가교 반응 촉매로써 NaOH로 구성된 변형 PVA 기반 포매용 레진을 연구하였다. 붕산 및 PVA와 NaOH의 함량이 증가함에 따라 응집력이 비례하게 증가하였으며, 10 wt% PVA 및 2 wt% 붕산, 그리고 0.3 wt% NaOH의 조성으로 제조된 레진을 이용한 절편 작업 시 손상없는 완전한 조직 절편을 얻을 수 있었고, 헤마톡실린 및 에오신 염색 테스트 결과 확실한 조직 영상을 확인할 수 있었다. 본 연구의 변형된 PVA 포매용 레진이 다양한 생체 조직의 신속한 조직학적 분석 효율을 향상시킬 수 있을 것으로 기대된다.
