      • 人蔘投與가 肺炎菌眼內炎에 미치는 影響에 關한 實驗的 硏究

        金容培 충남대학교 의과대학 지역사회의학연구소 1978 충남의대잡지 Vol.5 No.2

        The experimental endophthalmtis was obtaind by injection of about 50 thousands of pneumcocci into the anterior chamber of the rabbit's eyes for the purpose of stding the effects of ginseng on acute bacterial infection. Lage doses of ginseng extract(150 mg/kg) and small doses of ginseng extract(25 mg/kg) were administrated intraperitoneally for 6 days on each group from 2nd day of infection. The commparative observations were done for the effects of ginseng on pneumococcal endophthalmitis, and summarized as follows: A. Clinically 1. The corneal stromal edema appeared to be significantly aggravated in small doses of ginsneg adinistrated group than the others, and small doses of ginseng were thought to be harmfull than large doses of ginseng for endophthalmitis especially for cornea. 2. In large doses of ginseng administrated group, corneal edema showed different two patterns; a half of aggravation and the other half of improvement. 3. Control group showed a little improvement and no remarabe change in corneal edema. B. Histopathologically 1. Stromal edema and fibrosis of the cornea seemed to be more marked in small doses of ginseng administrated group than the others. 2. There was no remarkable difference between control group and large doses of ginseng administrated group, in the corneal changes. 3. Marked inflammatory changes were seen in not only iris or ciliary body but also vitreous or optic nerve, in the cases of severe endophthalmitis.

      • Toluene의 Rayleigh ratio와 온도 의존성에 관한 연구

        金容培 建國大學校基礎科學硏究所 1983 理學論集 Vol.8 No.-

        Rayleigh ratio has been measured for toluene as a funtion of temperature. The following relationship was obtained for a wavelengh of incident light of λ??=435.8nm; ??=(50.48+0.2638 t)×?? where t is temperature(℃). Light scattering photometer was calibrated with benzene purified by fractional distillation by using a value of Rayleigh ratio for benzene of ??=46.5×??. In order to verify the validity of the calibration molecular weight determination was run on sucrose. The values of Rayleigh ratio for toluene was compared with (a) similar data in the literature, (b) values calculated using the Einstein equation with ?? data, and (c) values calculated from various theorectical or empirical expression for ??. Best overall agreement of total ?? for toluene is found by using the Einstein equation with thermodynamic variable T.

        피판의 생존증대를 위한 국소적 고압산소 요법의 이용

        김용배 大韓成形外科學會 1994 Archives of Plastic Surgery Vol.21 No.2

        The hyperbaric oxygen theraphy has been cited as a sure method of helping improve chances of skin flap survival but it has yet to be widely utilized due to not only toxicity and other side effects such as renal bleeding and eardrum rupture, but also in conveniences such as infeasibility of entry into the oxygen tank for patients with poor systemic condition and infants. In contrast, regional hyperbaric oxygen theraphy shows no side effects associated with the systemic hyperbaric oxygen therapjy while having the advantage of being almost as effective as the latter method with a much simpler heatnext method for the patients. The author treated 23 compromized flaps with regional hyperbaric oxygen theraphy by using Topical Hyperbaric Oxygen Chamber(Fig. 1). In most cases, the flap survival was increase but partial necrosis of the flaps were noted in some cases(5/23) and the flap was totally lost in one flap. The mean elevation of arterial oxygen saturation after regional hyperbaric therapy was 6.9% and hereby reporting the above results, along with a discussion on related literature.

        연 폭로시 성별에 따른 혈중 Zinc Protoporphyrin의 양-반응 관계

        김용배,리갑수,황규윤,이성수,안규동,이병국,안현철,Kim, Yong-Bae,Lee, Gap-Soo,Hwang, Kyu-Yoon,Lee, Sung-Soo,Ahn, Kyu-Dong,Lee, Byung-Kook,Ahn, Hyun-Cheol 대한예방의학회 1999 Journal of Preventive Medicine and Public Health Vol.32 No.4

        Objectives : To evaluate whether a relation between blood lead and zinc proto porphyrin(ZPP) was modified by gender in Korean lead workers. Methods : A cross-sectional study was conducted with 1,304 male and 101 female subjects in 1997. The relation between blood lead and ZPP were evaluated with linear, exponential, and quadratic models. Then, the different effect of gender on the relation was examined by adding the interaction terms in the each model. Results : $Mean{\pm}SD$ of blood lead and ZPP level was different between male$(27.7{\pm}10{\mu}g/dl\;and\;51.3{\pm}23.4{\mu}g/dl)$ and female subjects$(22.5{\pm}9.2{\mu}g/dl\;and\;78.7{\pm}38.6{\mu}g/dl)$. After adjusting for possible confounders, the effect modification by gender was significant in linear$(\beta=1.119,\;p<0.001)$, exponential$(\beta=Exp(0.008),\;p<0.05)$, and quadratic model$(\beta=1.388,\;p<0.001)$. In separate analysis, a quadratic relation between blood lead and ZPP was shown in male lead workers$(\beta=0.036,\;p<0.001)$, but an exponential relation in female lead workers$(\beta=Exp(0.029), p<0.001)$. Conclusion : Our data showed that the increasing rate of ZPP in female were always higher than in male lead workers, suggesting that females were more susceptible to occupational lead exposure than males.

      • 우리나라 經營參加制度에 대한 從業員 意識構造의 實證的 分析

        金用培 청주대학교 대학원 1988 우암논총 Vol.4 No.-

        The relations between labor and capital was rather oppitive and conflicting at the beginning of industrialization in many developed countries. But the countries have carried out the participation of the labor unions in business administration these days. I think, in order to carry out the system effectively, the employers and workers should have a positive attitude and keep their equal rights. And they should remember that they are the equal partners each other in business, especially the employers should satisfy the worker's desires. And they should pursue the common goal-economic stability and highly developed society. For this goal, the democration of economy and business management should be carried out. Since the collective bargaining is not settled in Korea, the laborer's economic rights are not guaranteed. Also, the bilateral system of collective bargaining and the joint labor-management conference-the democratic system of business management-is tenuous. To solve the foregoing problems, it is certain that we should pursue the policy of improvement of labor-management relations through activation of the joint labor-management conference.

      • 가토 대동맥 평활근에서 인삼 알콜 추출물에 의한 Calcium 동원에 관한 연구

        김용배,이영호,강복순,강두희,Kim, Yong-Bae,Lee, Young-Ho,Kang, Bok-Soon,Kang, Doo-Hee 대한생리학회 1990 대한생리학회지 Vol.24 No.1

        There have been conflicting reports concerning the effect of Panax ginseng on the contractility of vascular smooth muscle, i.e., Panax ginseng extract has been reported to cause relaxation, contraction or to have no effect on the tension of vascular smooth muscle. A further investigation of $Ca^{++}$ stores which supply $Ca^{++}$ for contraction of vascular smooth muscle is needed to understand the underlying mechanisms of this conflicting effect of ginseng alcohol extract (GAE). The present study was intended to examine the sources of calcium mobilized for contraction of vascular smooth muscle by GAE. Aortic ring preparations were made from the rabbit thoracic aorta and endothelial cells were removed from the ring. The contractility of the aortic ring was measured under various experimental conditions and $Ca^{++}$ flux across the membrane of aortic ring and the sarcoplasmic reticulum and mitochondria were measured with a calcium selective electrode. The result were summarized as follows; 1) At low concentration of extracellular $Ca^{++}$, GAE increased the contractility of vascular smooth muscle in dose-dependent fashion except high concentration $Ca^{++}$ (1 mM). 2) In the presence of ryanodine, GAE still increased contractility of vascular smooth muscle as much as control group, but in the presence of caffeine, GAE increased it significantly. i.e. Their effects seemed to be additive. 3) In the presence of verapamil+lanthanum, and verapamil+lanthanum+ryanodine, the contractility of the vascular smooth muscle was decreased, but a dose dependent increase in vascular tension was still demonstrated by GAE although total tension was low. 4) GAE increased $Ca^{++}$ efflux from vascular smooth muscle cells, but have no effect on $Ca^{++}$ influx. 5) GAE increased $Ca^{++}$ efflux from sarcoplasmic reticulum and mitochondria vesicles. From the above results, it may be concluded that GAE increased the release of $Ca^{++}$ from sarcoplasmic reticulum, mitochondria or other intracellular $Ca^{++}$ stores of vascular smooth muscle, but it does not increase $Ca^{++}$ influx across the plasma membrane.
