池善得 충남대학교 대학원 1975 論文集 Vol.5 No.-
The effects of some autonomic drugs on the elevated intraocular tension of the rabbit were investigated. 1) Intravenous or local administration of acetylcholine, isoproterenol, a small dose of epinephrine and local large dose of epinephrine shortened the recovery time of the elevated intraocular tension to normal level. 2) Intravenous or local administration of norepinephrine and intravenous large dose of epinephrine lengthened the recovery time. 3) A small dose of intravenous dimethylphenylpiperazinium shortened the recovery time, while large dose of the former lengthened the latter. 4) Intravenous hexamethonium, bretylium, regitine, and small dose of atropine lengthened it. From the above results, it is suggested that there are cholinergic, adrenergic α and β receptor in the regulatory organs of the intraocular tension and autonomic nervous system plays an important role in regulating the intraocular tension.

폴리스틸렌 수지에 트리에틸렌테트라아민을 반응시켜 선형과 집게형의 킬레이트 수지를 합성하였으며, 이들 수지에 지지된 아민은 주로 적외선 스펙트럼으로 확인하였고, 전이금속이 수지에 흡착되는 속도를 측정하였다. 이 결과에서 얻어진 확산계수 및 활성화엔트로피 등이 보고된다. 흡착과정의 속도결정 단계는 입자를 통한 확산과정이다. Resins of polystyrene supported triethylenetetramine of linear and claw types have been prepared by the reaction of triethylenetetramine with chloromethylated polystyrene. The resin supported triethylenetetramines were principally characterized by infrared spectra. Kinetics of adsorption of transition metals on the resin have been investigated. This paper reports the results of the diffusion coefficients and entropies of activation. The rate determining step is a process of diffussion through the particle.
