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.

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.

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.

Restoration of functional and anatomic changes of kidney in UPJ stricture is one of most important subjects in urology. A clinical observation was made on the 28 cases (29 kidneys) of pyeloplasties for UPJ stricture from Jan. 1976 to Dec. 1981. Of them 20 cases (21 kidneys) were followed up for more than 6 months postoperatively. The following results were obtained; 1. The patients in this series were 22 males and 6 females, and 11 children and 17 adults. The left side was 3 times more frequently affected than the right. They symptoms on admission were mostly flank pain, palpable mass, and etc. 2. Preoperative status of UPJ was; UPJ stricture alone in 20, UPJ stricture with aberrant vessel in 4, UPJ stricture with stone in 3, and UPJ stricture with vesicoureteral reflux in 1 case. 3. Preoperative grade of hydronephrosis was closely related to each other in the functional and anatomic aspects of kidney. In general, children showed relatively more advanced hydronephrosis than adults and the degree of improvement of hydronephrosis postoperatively was similar to each other. 4. Anderson Hynes' method of pyeloplasty in most cases (20 kidneys) and simple pyeloureterostomy in 9 kidneys were performed, and results between both operations showed no difference. But Anderson Hynes' method was more effective in marked hydronephrosis such as giant hydronephrosis and simple pyeloureterostomy in mild hydronephrosis. 5. In cases in which UTI was present preoperatively, postoperative UTI tended more to persist than in those not complicated with preoperative UTI, and in both sides postoperative UTI mostly persisted for 2 months and disappeared within 6 months. 6. The period of nephrostomy and ureteral stent was not directly related to postoperative results, but nephrostomy without ureteral stent relatively showed good results. 7. Postoperative complication was UTI in 2, re-do pyeloplasty in 1 and secondary nephrectomy in 1 case. 8. Improvement Of hydronephrosis continued for about a year after operation. It is recommended that more careful attention should be paid for the first year and be continued to watch for consecutive 2 years.
