dc.description.abstract[한글] Greifenstein 및 Devault(1958)는 phenylcyclohexylamine 유도체의 마취성을 인지하여 사용해 오던 중 경련, 흥분 등 마취 후 오래 계속되는 정신적 후유증으로 임상에 사용되지 않았다. 그러나 Ketamine hydrochloride는 화학적으로 phencyclidine(CI-395)과 cyclohexamine(CI-400)과 유사한 nonbarbitrate계통의 약물로서 Domino등(1965)이 임상에 사용하여 인후반사의 유지와 정상 또는 야간 증가된 골격근긴장 및 순환계와 호흡계의 흥분작용을 동반하는 무통의 효과가 있음을 보고한 뒤, 수년 동안 정맥 및 근육주사를 하여 전 신마취제로 사용되어왔다. 그러나 각성기 흥분 또는 환상, 수술 후 불유쾌한 꿈 등 바람직하지 못한 psychotomimetic effects(Roberts, 1967: Wilson등, 1967: Albin 및 Dresner, 1969: Knox등, 1970: Bovill등, 1971: Winters, 1972; Lilburn등, 1978) 등이 있다는 보고도 있어 사용에 논란이 많으나 상용량으로는 중추신경계에 해리성효과(Domino등, 1965)외에 순환계, 호흡계의 기능억제를 하지 않아 널리 사용되고 있다. Ketaminc이 순환계와 호흡계에 미치는 영향에 대해서는 여러 가지 연구보고가 많으나 위 장관운동에 대한보고는 별로 많지 않다. 이에 본 저자는 닭의 십이지장을 이용하여 Ketamine의 장운동에 대한효과를 검토하였다. 실험 동물로는 체중 1.2∼1.5kg 내외의 닭의 십이지장을 분리, 적출 하여 절편을 만들었으며, 인체의 십이지장은 위암환자에서 얻은 일부 절편에서 지방조직을 제거한 후 절편을 만들어 38℃의 Tyrode액을 포함한 이중벽 초자제 muscle chamber에 고정하고 산소를 공급하여 자발운동을 유발시키며 force displacement transducer(FTO3C)를 통해 polygraph에 묘사했다. 실험성적을 종합하면 다음과 같다. 1. Ketamine은 인체 십이지장관 절편에는 별 영향을 주지 않았으나, 닭 십이지장관 절편에서는 이완작용을 나타냈으며 epinephrine, norepinephrine, isoproterenol의 장관이완작용에 상승작용을 나타냈다. 2. Ketamine의 닭 십이지장관 이완작용은 adrenergic receptor 차단제에 의해 봉쇄되지 않았다. 3. Ketamine은 닭 및 인체 십이지장관 절편에서 항 choline성 작용을 나타냈다. 이상의 성적을 종합해 보면 Ketamine은 닭 및 인체의 장에서 항 choline성 효과를 나타내며 adrenergic receptor와는 관계없이 평활근자체에 직접 작용하여 장운동을 억제하는 것으로 생각된다. [영문] In the late 1950, Greifenstein and associates have studied the properties of phenylcyclohexylamine derivatives and reported that these chemicals produced amnesia, analgesia, catatonis and catalepsy. Phencyclidine was the first of these durgs used in clinical anesthesia, but convulsive movement as well as excitatory behavior discouraged the use of the agent in human beings. Continued research for a more suitable derivative of phencyclidine with similar analgesic action, but shorter duration and lesser psychotomimetic action led McCarthy and Chen to investigate the pharmacologic properties of a large series of compounds. One of these, 2-0-chlorophenylcyclohexamine, was shown to have some advantages. Ketamine hydrochloride, chemically related to both phencyclidine and cyclohexamine, proved to be more satisfactory for clinical anesthesia. Clinical investigations were begun in 1965 by Domino's group who first termed it "dissociative" anesthesia. As noted by Pender, the clinical signs of anesthesia with ketamine are completely different from those seen with conventional intravenous agents and gaseous compounds. Ketamine acts rapidly on intravenous or intramuscular administration to produce a state characterized by catalepsy, analgesia and amnesia. It is devoid of sedation, hypnotic or convulsive properties. Normal pharyngeal-laryngeal reflexes are maintained and skeletal tone remains normal or increased. Since the introduction of ketamine by Domino's group, numerous reports have appeared to explain various aspects of the cardiovascular response (increased cardiac output, hypertention, little or no change in peripheral resistance) and respiratory response. However there are few reports on the effect of ketamine on intestinal motility. Thus we have made a study to observe the effect of ketamine on the intestinal motility of chickens. Strips of isolated muscle, 1cm long, from adult fowl weighing 1.2-1.5Kg and isolated smooth muscle of a patient with stomach cancer, were suspended in a muscle chamber containing Tyrode's solution into which was bubbled oxygen gas. The solution was kept constant at 38℃and contraction of the preparations was recorded on a polygraph. After being washed several times with fresh solution, the muscle strips attained constant motility and tonus. Ketamine and other drugs were added in various concentrations to the chamber. The results are as follows: 1. Ketamine did not exert any effect on human intestinal motility. It relaxed fowl intestinal muscle strips and potentiated the effect of epinephine, norepinephrine, and isoproterenol. 2. The relaxing effects of ketamine of fowl intestinal muscle strips were not abolished by adrenergic blocking agents. 3. Ketamine demonstrated anticholinergic effect on the intestinal motility of the human and fowl. From the above results, it may be concluded that ketamine exerts a anticholinergic effect and depressant effect on intestinal motility of fowl without relation to adrenergic receptors.-
