李英培 건국대학교 1985 論文集 Vol.21 No.1

A pot experiment was conducted to evaluate three granular blasticides treated into the seedling-box one day before the mechanical transplanting of rice on the control effect of rice blast disease. Among tested blasticides, Tricyclazole showed highest control and longest residual effects. Over 90% control of leaf blast were maintained unto 54 days after Tricyclazole treatment to seedling-box, and it showed 85.6% control at 64 days after treatment and 61.10 control at even 74 days after treatment. Isoprothiolane showed similarly high effectiveness to Tricyclazole unto 34 days after treatment to seedling-box, 60% control of leaf blast was maintained thereafter upto 64 days after treatment and it showed 43.3% control at 74 days after treatment. And Probenazole showed 84.4 % control of blast disease at 24 days after treatment, 66.9% at 34 days after treatment and even lower effectiveness at 44 days after treatment and thereafter.

Purpose : Recent evidence suggests a possible role for leukocytes in brain injury following ischemia and reperfusion. This study examined the temporal profile of ischemic tissue damage and leukocyte response after transient middle cerebral artery occlusion(MCAO) with reperfusion in the mouse. Methods : Focal cerebral ischemia was made by temporary occluding of the stem of the proximal MCA. Two groups of the mouse were investigated : (1) sham operation(n=10), and (2)those having the arterial occlusion released after 90 minute(n=20). By 4 hours(n=10) and 24 hours(n=10) after the onset of ischemia-reperfusion, fluorescein videoimages were under-taken in the pial venules of the mouse using a closed cranial window technique. Rhodamine 6G was administered as a $80-100{\mu}l/min$ i.v. loading dose and a $30-40{\mu}l/min$ i.v. maintenance dose in saline to selectively label circulating leukocytes. Neuropathologic evaluation for brain injury was accomplished using the histochemical stain 2,3,5-triphen-yltetrazolium chloride(TTC) and hematoxylin and eosin(H & E) stain. Results : The mean number of adherent leukocytes to cerebral venules in the 90 minutes MCAO and 24 hours reperfusion group were $306{\pm}24$ compared with $72{\pm}8$ in the sham operation group. In the TTC staining method, the cortical infarct affecting 34.8% of hemispheric volume were created in all of animals (n=10) undergoing 90 minute MCAO with 24 hours reperfusion, but the infarcted area were not found in the other(sham operation and 90 minute MCAO with 4 hours reperfusion)groups. In the H & E stain, the brain tissue following 90 minute MCAO with 4 hours reperfusion revealed only a pyknosis of the nuclei with shrunken cytoplasm, but infiltrated leukocytes were not observed. After 24 hours of reperfusion, a many leukocytes were infiltrated within parenchyma and blood vessles. Conclusions : These findings demonstrate the feasiblity of continous in vivo monitoring of leukocyte adherence in cerebral venules and suggest that reperfusion induced leukocyte adherence to venular endothelium may contribute to tissue injury following focal cerebral ischemia.

Objective:Our aim is to evaluate the usefulness of fluid-attenuated inversion recovery(FLAIR) magnetic resonance(MR) imaging for detection of acute subarachnoid hemorrhage(SAH) compared with non-contrast-enhanced computed tomography(CT). Methods:We compared FLAIR MR images with non-contrast-enhanced CT scans in 34 patients with acute SAH. Findings of SAH on CT and MR images were graded as 0(absence), 1(suspicious), and 2(definite) in the cerebral sulci, sylvian fissures, basal cisterns, and cisterns of the posterior cranial fossa. We also compared FLAIR MR images of 34 patients with those of 35 normal subjects, and then the sensitivity, specificity, and diagnostic accuracy of FLAIR MR image for detection of acute SAH were calculated. Results:FLAIR MR image was superior to CT in detecting SAH in the cranial fossa posterior(1.41±0.74 vs. 0.78±0.80, p<0.05) and cortical sulci(1.11±0.80 vs. 0.70±0.83 p<0.05). There was no significant difference between FLAIR MR image and CT in detecting SAH in the basal cisterns and sylvian fissures. The sensitivity, specificity, and diagnostic accuracy of FLAIR MR image for detection of SAH were 100% in all. Conclusion:FLAIR MR image is useful in detecting acute SAH, especially in patients with SAH in the posterior cranial fossa and cerebral sulci. Key words:Subarachnoid hemorrhage;Magnetic resonance imaging;Brain CT;Cranial fossa posterior.

감나무의 Ethanol 추출액(抽出液)이 척출가토(剔出家兎) 장관운동(腸管運動)에 미치는 영향(影響)

이영배,신홍기,김기순,Lee, Young-Bae,Shin, Hong-Kee,Kim, Kee-Soon 대한생리학회 1977 대한생리학회지 Vol.11 No.1

Diospyros Kaki Thunberg is the species of persimmon tree that grows in Korea. Although its fresh or dried fruits are often served as a desert, it has little been known if persimmon tree has any specific pharmacological action. The leaves and branches of persimmon tree has long been used as folk remedies for palsy and frostbite in the southern part of Korea and it is also in use for the treatment of hiccup and nocturnal enuresis in chinese herbal medicine. Recently it was reported that an intravenous administration of Diospyros Kaki Thunberg ethanol extract (KTEE) into the animals lowered arterial blood pressure. Lee concluded from his study on the mechanism of depressor action of KTEE that at least a part of depressor response he observed was caused by acetylcholine-like action of KTEE. On the other hand little study has been made on the effect of KTEE on the motility of isolated animal intestines. Therefore the present study was undertaken to investigate effect of KTEE and the mechanism of its action on the motility of isolated rabbit duodenum. Ethanol extract of Diospyros Kaki Thunberg was prepared by boiling 1 kg of dried branches of persimmon tree in 1 liter of ethanol and the motility of isolated rabbit duodenum was recorded on physiograph by means of force transducer connected with Magnus apparatus. Doses of KTEE used were $5{\times}10^{-4}gm/ml,\;1{\times}10^{-3}gm/ml,\;and\;2{\times}10^{-3}gm/ml$. And the isolated duodenum was separately pretreated with acetylcholine $(5{\times}10^{-7}gm/ml)$, pilocarpine $(2.5{\times}10^{-6}gm/ml)$, histamine $(5{\times}10^{-6}gm/ml)$ and barium chloride $(2.5{\times}10^{-5}gm/ml)$ in order to find out interactions of these drugs with KTEE. The results obtained are as follows: 1. At doses of $5{\times}10^{-4}gm/ml,\;1{\times}10^{-3}gm/ml$ KTEE reduced contractions of isolated duodenum, while tonus as well as contaction of duodenum were depressed with $2{\times}10^{-3}gm/ml$ of KTEE. 2. Since the inhibitory effect of KTEE on the intestinal motility was not blocked by pretreatment with acetylcholine, pilocarpine, and barium chloride, it was strongly suggested that the inhibitory action of KTEE on intestinal motility is mainly Caused by its antihistamine effect. 3. It is also concluded that the principal substance of KTEE responsible for inhibition of intestinal motility may also have a vasodilating activity and would not be an acetylcholine-like substance in case it is same substance as that cause depressor responses.

Metrizamide를 이용한 척수조영술의 임상분석

이영배,석종식,최덕영,임광세 대한신경외과학회 1982 Journal of Korean neurosurgical society Vol.11 No.4

Metrizamide lumbar myelography were performed in 150 patients with suspected herniated lumbar disc. The examination is easier to perform than with gas or iophendylate. The advantage of metrizamide over gas or iophendylate are the improved root sleeve visualization and examination of small structure such as root, root pocket and blood vessel. And then this is a higher percentage of diagnostic accuracy than can be obtained with other myelogram. Most of adverse reactions during and after myelography are mild and transitory, and no serious adverse reactions occured. It probably has a lower neurotoxicity than any other water soluble contrast agent.
