Abstract

Concanavalin-A, lectin extracted from Korean native plant “Banha”(Pine-llia Termata) and their conjugation products with tyrosine and 5-iodo-6-aminouracil were labelled by radioactive iodiae-125, and these labelled compounds were subjected to a hemagglutination test in vitro. The labelling procedures were presented with respect to labelling yield and the trends on the conjugation reaction of lectin with various amino acids were discussed. The preliminary results on the hemagglutination tests against cancer tissues were presented and the potential clinical applications of these labelled compounds were discussed.

Concanavalin-A, 한국산 반하(半夏)로부터 주출된 Lectin 및 이들과 tyrosine 또는 5-iodo-6-aminouracil을 결합시킨 화합물들을 각각 방사성 요오드-125로 표지 하였으며 표지된 화합물들을 사용하여 생체외부 시험법으로 혈액응고 시험을 실시하였다. 표지반응에 관하여 표지수율과 함께 그 실험조건을 보고하였으며 Lectin과 여러 아미노산계통 화합물들과의 결합반응성을 논의하였다. 암세포에 대한 혈액응고 시험결과를 보고하였으며 이들 표지화합물들의 임상적 실용전망에 관하여서도 논의하였다.
