발생중인 계배의 날개형성에 미치는 retinoic acid(RA)의 효과를 알아보았다. RA처리는 날개원기의 전단부로 부처 거울상을 띤 지골의 복제를 유발하였다. 이러한 RA처리에 따른 지골의 복제 효과는 발생시기 및 처리량에 의존적이었다. 즉 stage 18시기의 날개원기에 RA를 처리했을 때 최대의 지골 복제 효과가 유발되었으며, 20mg/ml 의 RA 용액으로 처리했을 때 최대의 지골 복제 효과가 나타났다. 이러한 실험결과는 RA 처리가 날개원기 세포의 positional value를 전후축 상에서 후위화하기 때문에 나타나는 것으로 해석될 수 있으며, 후위화의 정도는 발생단계 및 처리량에 의존적임을 시사하고 있다.

Gamma-ray induced copolymerization of phenyl acetylene with styrene is compared with that of the Ziegler catalyzed. The reactivity of styrene is greater than that of phenyl acetylene in the gamma-ray induced polymerization but much less than that of phenyl acetylene in the Ziegler catalyzed. The resulting copolymer is identified by means of DTA and spectrophotometry. Further, the liquid scintillation counting of styrene-${\alpha}-C^{14}$clarified the relative composition of the copolymers.

In the present investigation, the anti-inflammatory activity of glycyrrhetic acid derivatives (abbreviated as AMKOA, 28-OMKOA, 30-OMKOA) was compared with hydrocortisone and sodium salicylate by a new anti-inflammatory test, utilizing the chorio-allantoic membrane of the chick embryo, which is outstandingly suitable for large scale screening of new compounds. The anti-inflammatory activity of the glycyrrhetic acid derivatives was similar to hydrocortisone and superior to sodium salicylate.

Slate-plastic composite was prepared by impregnating methyl methacrylate monomer into the slate and subsequent curing the monomer either by gamma radiation or by thermal-catalytic method. Experiments were carried out to determine the polymerization rate and to investigate the properties of the composite. Significant improvements in flexural strength, water absorbability and acid resistance were observed in the products. Differences in properties between the composites obtained via two different methods were discussed as well as the cause of such results.
