5.Production of IL-15 and lts Functional Study in Mouse Splenocyte Activation.
Korean Journal of Immunology 1999;21(4):297-302
After the synthesis of IL-15 cDNA from the total RNA of mouse spleen, it was inserted into the prokaryotic expression vector, pRseta, and eukaryotic expression vector, pcDNA3.0, respectively. Subsequently, the insertion of gene and open reading frame were confirmed by sequencing of each plasmid, respectively. Using pRseta- IL-15 plasmid, the recombinant IL-15 protein was induced by IPTG under BL21 (DE 3) host cells and recombinant IL-15 was expressed at 14.5 KDa with time. Then, IL- 15 was separated by His-tag affinity chromatography and analyzed by SDS-PAGE to yield soluble IL-15 at 14.5 KDa as monomer and 29.0 KDa as dimer. In order to inspect the function and contribution of IL-15, the in vitro experiment was established using mononuclear cells separated from the mouse spleen. After 48h exposure of PHA to mouse splenocyte and 24h treatment with recombinant IL-15, the effects of cytokine inductions inspected against IL-2, IL-6, IL-10, IL-12, IFN-r, and GM-CSF. The results showed that comparing with the control, IL-6 increased, IL-2, IL-12 and IFN-r increased and similar, and GM-CSF decreased. In addition, the direct injection of pcDNA3.0-IL-15 plasmid into mice gave the similar results to in vitro studies. Namely, IL-6 and IL-12 increased, and IL-2, IFN-r and GM-CSF were similar or decreased. IL-10 was not induced in in vitro and in vivo experiments. These results suggested that the IL-15 induce the splenocyte activation and can be an important factor in proliferation and fuction recovery of weakened T-cell.

6.Intravenous Infusion of Clonidine Potentiates Postoperative Analgesia Induced by Fentanyl.
Korean Journal of Anesthesiology 1997;33(2):348-354
BACKGROUND: Clonidine, an alpha 2adrenergic agonist, has nonopiate antinociceptive properties which might be an alternative for postoperative analgesia free of undesirable effects from opioid. The aim of this study was to evaluate the postoperative analgesic effects of intravenous (IV) infusion of clonidine. METHODS: Seventy two healthy patients who undergoing cesarean section or gynecological surgery under general anesthesia were randomly divided into three groups as follows; the patients of group l received fentanyl (100 g bolus + 0.5ug/kg/hr) alone, the patients of group II received clonidine (100ug bolus + 10ug/kg/hr) and same dose of fentanyl, and the patients of group III received clonidine (200 g bolus + 20ug/kg/hr) and same dose of fentanyl. Pain score using a visual analogue scale (VAS), sedation score and any side effects were evaluated at 1, 6, 24 and 48 hours after starting the infusion. RESULT: Patients in group II and group III were more pain relieved during 48 hours and more sedated compared to group I at 1 hr, but there were no significant difference of side effects. CONCLUSION: Continuous IV infusion of clonidine potentiates postoperative analgesia induced by fentanyl.

7.A Study on Developing Computer Models of Neuropsychiatric Diseases.
Journal of the Korean Society of Biological Psychiatry 1999;6(1):12-20
In order to understand the pathogenesis and progression of some synaptic loss related neuropsychiatric diseases. We attempted to develop a computer model in this study. We made a simple autoassociative memory network remembering numbers, transformed it into a disease model by pruning synapses, and measured its memory performance as a function of synaptic deletion. Decline in performance was measured as amount of synaptic loss increases and its mode of declines is sudden or gradual according to the mode of synaptic pruning. The developed computer model demonstrated how synaptic loss could cause memory impairment through a series of computer simulations, and suggested a new way of research in neuropsychiatry.

Pigmented Bowen's disease (PBD) is a rare variant of Bowen's disease(BD). Most of the reported cases showed pigmented patches or thin plaques. Thus its clinical manifestations may simulated other various pigmented skin lesions. We experienced 2 cases of PBD in patients with multiple BD developed after taking Korean proprietary pills (KPP, "Hwan-Yak"), which were suspected to contain certain amount of arsenics. Both patients also showed arsenical keratosis on their palms and soles. The darker pigmentation of the PBL led us to differentiated them from melanoma.

9.A Study on the Mobile Medical Service Program.

Korean Journal of Preventive Medicine 1978;11(1):86-97
The mobile medical service has been operated for many years by a number of medical schools and hospitals as a most convenient means of medical service delivery to the people residing in such area where the geographical and socioeconomic conditions are not good enough to enjoy modern medical care. Despite of official appraisal showing off simply with numbers of outpatients treated and medical persons participated, however, as well recognized, the capability (in respect of budget, equipment and time) of those mobile medical teams is so limited that it often discourages the recipients as well as medical participants themselves. In the midst of rising need to secure medical service of good quality to all parts of the country, and of developing concept of primary health care system, authors evaluated the effectiveness of and problems associated with mobile medical service program through the community diagnosis of a village (Ope-Myun, Kwangju-gun) to obtain the information which may be helpful for future improvement. 1. Owing to the nationwide Sae-Maul movement powerfully practiced during last several years, living environment of farm villages generally and remarkably improved including houses, water supply and wastes disposal etc. Nevertheless, due to limitations in budget, time and lack of knowledge (probably the most important), these improvements tend to keep up appearances only and are far from the goal which may being practical benefit in promoting the health of the community. 2. As a result of intensive population policy led by the government since 1962, there has been considerable advances in understanding and the rate of practicing family planning through out the villages and yet, one should see many things, especially education, to be done. Fifty eight per cent of mothers have not received prenatal check and the care for most(72%) delivery was offered by laymen at home. 3. Approximately seven per cent of the population was reported to have chronic illness but since only a few(practically none) of the people has had physical check up by doctors, the actual prevalence of chronic diseases may reach many times of the reported. The same fact was observed also in prevalence of tuberculosis; the patients registered at local health center totaled 31 comprising only 0.51% while the numbers in two neighboring villages (designated as demonstration area of tuberculosis control and mass examination was done recently) was 3.5 and 4.0% respectively. Prevalence rate of all diseases and injuries experienced during one month(July, 1977) was 15.8%. Only one tenth of those patients received treatment by physicians and one fifth was not treated at all. The situation was worse as for the chronic patients; 84% of all cases either have never been treated or discontinued therapy, and the main reasons were known to be financial difficulty and ignorance or indifference. 4. Among the patients treated by our mobile clinic, one third was chronic cases and 45% of all patients, by the opinion of doctors attended, were those who may be treated by specially trained nurses or other paramedics (objects of primary care). Besides, 20% of the cases required professional managements of level beyond the mobile team's capability and in this sense one may conclude that the effectiveness(performance) of present mobile medical team is quite limited. According to above findings, the authors would like to suggest following for mobile medical service and overall medicare program for the people living in remote country side. 1. Establishment of primary health care system secured with effective communication and evacuation (between villages and local medical center) measures. 2. Nationwide enforcement of medical insurance system. 3. Simple outpatient care which now constitutes the main part of the most mobile medical services should largely be yielded up to primary health care unit of the village and the mobile team itself should be assigned on new and more urgent missions such as mass screening health examination of the villagers, health education with modern and effective audiovisual aids, professional training and consultant services for the primary health care organization.
