The radial artery as a graft for myocardial revascularization was introduced by Carpentier in the early 1970s. Mid-term results were unfortunately discoura ing, and the clinical experience with this graft was interrupted. At the end of the 1980s, these authors reproposed the same arterial conduit with more satisfying results, because of improved technique and pharmacological management of the graft. Between October 1994 and July 1995, 36 patients underwent myocardial revascularization with a radial artery graft in Seiong General Hospital. Left internal mammary artery was concomitantly used as a pedicled Vift in 34 patients. Fifteen patients (42%) had a complete arterial waft revascularization. A total of 12) distal anastomoses were performed (average 3.4 per patient), including 36 left internal mammary artery wafts (two sequential in 2 patients), and 23 saphenous vein grafts. The remaining 64 distal anastomoses were perFormed with radial artery grafts (mean 1.8 per patient). The radial arteries were anastomosed to the circumflex (n=38), diagonal (n= 18), right coronary(n=G), and left anterior descending coronary artery(n=2). The percent ge of radial artery graft anastomoses (64) to the total anastomoses(123) was 52%. The radial artery was used as a single graft in 10 patients, as a sequential graft in 25 patients, and two grafts in 1 patient. Twenty patients underwent associated procedures coronary endarterectomy (14), coronary artery patch angioplasty (4), mitral valve repair (1), and repair of ventricular septal rupture (1). One patient died of low cardiac output syndrome and the others had no perioperative myocardial infarction. There are no ischemic and functional complications in the arm or hand aftcr removal of the radial artery. Only 1 patient required reexploration of the am, for the hematoma evacuation, and 2 patients complained transient thumb dysesthesia of the side of the havested arm. This dysesthesia improved within one month. Postoperative angiovaphic controls were obtained in 11 patients(31%) postoperative 79 to 210 days (mean 126 days). The patency rate were as follows : left internal mammary artery (100%), saphcnous vein (100%), and radial artery(95%). We concluded that the radial artery is useful alternative graft, but long term clinical and angiographic studies are required to derterminc whether wider application is warranted.
This study was performed to evaluate the characteristics of smoking behavior and the effects of smoking on clinical symptoms and level of serum prolactin in schizophrenic patients. Methods : 76 male schizophrenic patients answered the questionnaire about the characteristics of smoking patterns. And patients were assessed by brief psychiatric rating scale(BPRS), positive and negative syndrome scle(PANSS), Hamilton rating scale for depression(HAM-D), assessment for involuntary movement scale(AIMS) and symptom checklist 90 R(SCL-90-R). Serum prolactin levels were measured by enzymeimmunoassay. Results: 1) The frequences of drinking coffee were significantly higher in smokers. The reasons for smoking were to relieve tension, to avoid boredom, due to habit and to do with friends. 80.1% of smokers tried quitting, but smoking was relapsed due to craving and withdrawal symptoms. 2) No significant difference was seen in mean neuropeltic doses, scores of PANSS and AIMS. But as for BPRS, scores of anxiety/depression subscale were significanly lower in smokers. Scores of HAM-D and scores of interpersonal sensitivity and phobia among SCL-90-R were significantly lower. 3) Levels of serum prolactin were significanlty lower in smokers. Conclusion : These findings suggest that in schisophrenia smoking relieves anxiety and depression subjectively But decreased prolactin levels may suggest that the possibility of increased dopamine in CNS.

Objective : Previous studies have suggested an association between sleep-related breathing disorder (SRBD) and several psychological problems, and there were increasing recognition of the link. The purpose of this study is to evaluate the characteristic profiles of MMPI and SCL-90-R in patients with SRBD. Methods : This study consisted of 80 SRBD patients(73 men, 7 women) referred from Sleep Disorder Clinic of Dong-A University Hospital, Busan, Korea. Basic informations including demographic findings and physical examination were collected. Subjects completed the Epworth Sleepiness Scale(ESS), Minnesota Multiphasic Personality Inventory(MMPI), and Symptom Check List-90-Revision (SCL-90-R) prior to standard overnight polysomnography that was performed at hospital sleep laboratory. SRBD was divided into two groups of primary snoring(PS) and obstructive sleep apnea(OSA) according to polysomnographic findings. Results : SRBD showed significant elevation rate of Hs, D, and Hy scales of MMPI and SOM scale of SCL-90-R, which exceeded the rate expected in normal individuals(>5%, 2SD). On comparison of clinical scales of SCL-90-R, OSA group had significantly greater mean score than that of PS group in terms of O-C, DEP, PAR, GSI(p<0.05), SOM and PST(p<0.01). OSA group also showed significantly higher elevation rate in Hs scale of MMPI and SOM scale of SCL-90-R than that of PS. Among OSA group, three scales of MMPI(D, Pt, Si) and three scales of SCL-90-R(ANX, PAR, PSDI) had significant correlation with some PSG variables including total sleep time and sleep efficiency. Among PS group, two scales of MMPI(Hy and Pt), elevation rate of MMPI scales and three scales of SCL-90-R(I-S, PAR, PSDI) had significant correlation with some PSG variables including sleep efficiency, sleep latency and REM sleep percent. Conclusion : The above results suggest that SRBD show neurotic profiles in MMPI and SCL-90-R. This study also clearly indicates that PS group are suffered from clinically meaningful psychiatric symptoms, which are quantitatively lessened but qualitatively similar as compared to that of OSA group.

The development of calvarial bones is tighly co-ordinated with the growth of the brain and needs of harmonious interactions between different tissues within the calvarial sutures. Premature fusion of cranial sutures, known as craniosynostosis, presumably involves disturbance of these interactions. Mutations in the homeobox-containg gene Msx2 cause human craniosynostosis syndrome. Msx genes, which are consist of Msx1, Msx2 and Msx3, are homeobox-containg transcripton factors, and were originally identified as homologue of Drosophila msh(muscle segment homeobox) gene. Msx1 and Msx2 genes, expressed mostly in overlapping patterns at multiple site of tissue interactions during vertebrate development, are associated with epithelial-mesenchymal interactions during organogenesis, targets of BMP and FGF signaling. To elucidate the function of Msx genes in the early morphogenesis of mouse cranial suture, we analyzed the expression of them by in situ hybridization during embryonic(E15-E18) stage, and did vivo experiments in E15.5 mouse using rhBMP-2, rhFGF-2 protein soaked bead. In the sagittal suture, Msx1 was expressed in the mesenchyme of suture and the dura mater, Msx2 was intensely expressed in the sutural mesenchyme and the dura mater. In the coronal suture both of Msx genes were expressed intensely in the sutural mesenchyme and expressed in the periosteum also. Msx1 had a broader expression pattern than Msx2. BMP2 beads induced expression of both Msx1 and Msx2, FGF2 beads induced expression of Msx1, but not Msx2. Taken together, these data suggest that Msx1 and Msx2 genes have important role in regulating the morphogenesis and maintenance of embryonic cranial suture. Both of Msx genes are expressed similarly but because of their upstream signaling, they function dependently or cooperatively according to change of signaling molecule.
Background : In acute lung injury, activated neutrophils play an important role in tissue damage. For neutrophils to participate in lung inflammation, chemotactic factors released from mononuclear phagocytes are needed to bring these cells to the local site of inflammation, with interleukin-8 (IL-8) being one of the most specific and important chemotactic factors for neutrophils. IL-8 also induces the expression of adhesion molecules and activates neutrophils to release various inflammatory mediators. Lipopolysaccharide(LPS) is one of the most important causes of adult respiratory distress syndrome and can cause release of many inflammatory cytokines including IL-8 leading to acute lung injury. But little is known about the regulatory mechanism of LPS-induced IL-8 gene expression in mononuclear phagocytes. Method : Human alveolar macrophages(HAM) and peripleral blood monocytes(PBMC) were isolated from healthy volunteers. Time and dose relationship of LPS-induced IL-8 mRNA expression was observed by Northern blot analysis. To evaluate the regulatory mechanism of LPS-induced IL-8 gene expression, pretreatment of actinomycin D(AD, $5{\mu}g/ml$) and cycloheximide(CHX, $5{\mu}g/ml$) was done and Northern blot analysis for IL-8 mRNA and ELISA for immunoreactive IL-8 protein in culture supernatant were performed. Results : 1) In HAM, dose and time dependent LPS-induced IL-8 mRNA expression was observed with peak mRNA level at 8 hours post-stimulation. 2) In PBMC, dose and time dependent LPS-induced IL-8 mRNA expression was also observed with peak mRNA level at 4 hours post-stimulation. 3) AD decreased expression of LPS-induced IL-8 gene expression at both mRNAand protein levels in both types of cells. 4) CHX decreased expression of LPS-induced IL-8 gene expression at protein level in both cell types but in HAM, superinduction of IL-8 mRNA was observed while decreased expression of IL-8 mRNA was observed in PBMC. Conclusion : Time and dose dependent LPS-induced IL-8 gene expression was observed in mononuclear phagocytes which is at least partly regulated pretranslationally. LPS-induced IL-8 mRNA expression in HAM needs no de novo protein synthesis and may be under the control of a labile repressor protein while de novo protein synthesis may be needed in PBMC.

Purpose : This study aimed to assess the mechanical properties of the abdominal aorta in school-aged patients treated for Kawasaki disease and in normal, healthy children. Methods : This study examined 28 children with Kawasaki disease who had been followed up on and 30 healthy subjects of the same age and gender. We recorded systolic (Ps) and diastolic (Pd) blood pressure values and the aortic diameter at both minimum diastolic (Dd) and maximum systolic (Ds) expansion using two-dimensional echocardiography. These measurements were used to determine 1) aortic strain: S=(Ds-Dd)/Dd; 2) pressure strain elastic modulus: Ep=(Ps-Pd)/S; and 3) normalized Ep: $Ep^*=Ep/Pd$. Results : Ep (P=0.008) and $Ep^*$ (P=0.043) of the Kawasaki disease group were relatively high compared to those of the control group. Ep (P=0.002) and $Ep^*$ (P=0.015) of patients with coronary aneurysm were also relatively high compared with those of patients without coronary aneurysm, but lipid profiles did not differ, except for homocysteine (P=0.008). Therefore, in patients with coronary aneurysm, aortic stiffness was higher, compared to not only the control group but also patients without coronary aneurysm. However, in patients without coronary aneurysm, aortic stiffness was not significant, different compared to the control group. Conclusion : Measuring aortic distensibility may be helpful in assessing the risk of early atheroscletic change in the long-term management of Kawasaki disease.

Mucopolysaccharidosis type VI (MPS VI) is a rare disease caused by the mutation of ARSB with prevalence range from 1/5,000 in northeast Brazil to 1/2,057,529 births in Czech Republic. In Asia, there is only one published figure in Taiwan of about 1/833,000 births. The exact prevalence in the Korean population is unknown, but we estimated the incidence of MPS VI is about 0.03/100,000 live births. Enzyme replacement therapy (ERT) with recombinant human Arylsulfatase B (rhASB) is a modality for the treatment of MPS VI that reduces the excretion of urine glycosaminoglycan (GAG) and improves joint motion, pulmonary function, and endurance. We presented the clinical features, molecular analysis and outcome of ERT in three Korean MPS VI patients. All patients had the typical characteristic clinical features of MPS IV. Short stature, dysostosis multiplex, corneal opacity and valvular heart disease were found at first presentation, while restrictive lung disease and carpal tunnel syndrome developed later in all patients. Molecular analysis demonstrated novel missense and nonsense mutation in the patients, including p.Ile 67Ser, p.Gly328Arg, $p.Arg191^*$, p.Asp352Asn, and p.Gly17Asp. After ERT, urine GAG was decreased in all patients. Skeletal involvement, corneal opacity, heart valve abnormalities and pulmonary function were not improved with ERT, but it had a better outcome on regarding joint motion and endurance. One patient underwent allogeneic bone marrow transplantation (BMT) prior to ERT, but their clinical response was not improved much after BMT. This study demonstrates clinical phenotypes and molecular analysis of the severe form of MPS VI in Korean patients.
Purpose : To find and solve the common problems of peritoneal dialysis(PD) by analysing the clinical data of pediatric PD performed in Korea. Methods : 264 cases of CAPD and acute PD had been performed from Nov.1987 to Oct. 1997 in 17 institutions of pediatric nephrology in Korea. Results : CAPD was performed in 114 cases. The mean age of the patients was $10.5{\pm}6.6$ years and male to female ratio was 1.4:1. The original renal diseases of ESRD were proven in 92 cases($80\%$). The common renal disease of ESRD were FSGS($17\%$), reflux nephropathy ($11\%$), chronic glomerulonephritis($9.6\%$). Mean duration of CAPD was $20{\pm}16.9$ months. Peritonitis was the most common complication and incidence was one episode/18.2 patient-months. Other complications were exit site infection in 10 cases, obstruction in 7 cases, leakage of dialysate in 6 cases. The most common etiologic organism of peritonitis was staphylococcus aureus and the next was staphylococcus coagulase(-). Acute PD was performed in 150 cases. Most common underlying causes were congenital heart disease, hemolytic uremic syndrome, sepsis and dehydration. The mean duration was $10.3{\pm}11.3$ days. The most common complication was peritonitis($20.6\%$). The most common etiologic organism was staphylococcus aureus and coagulase(-), acinetobactor and pseudomonas. Conclusion : Reflux nephropathy should be emphasized in early diagnosis and treatment to prevent ESRD. Incidence of congenital anomaly($7\%$) as a original disease of ESRD was relatively low in Korea. Growth status was not significantly improved after CAPD. In acute PD, the incidence of peritonitis was rapidly increased at 2weeks after beginning of dialysis.
Background : Steroid therapy has been shown to improve the clinical outcome in acute respiratory distress syndrome (ARDS) patients with histological evidence of fibroproliferation in the lung tissue and no identifiable source of infection. Because the histopathological features of acute interstitial pneumonia(AIP) are identical with that of ARDS, early steroid therapy was used in AIP patients who had histological evidence of fibroproliferation in the lung tissue and no identifiable source of infection. We analyzed seven years of our experience to evaluate the efficacy of early steroid therapy in AIP. Materials and Methods : A retrospective review was performed on AIP patients who received steroid therapy within 7 days of mechanical ventilatory support in Dankook university Hospital between May 1995 and May 2002. AIP was diagnosed clinically by ARDS without a known cause of the etiology and pathologically by a lung biopsy showing a fibroproliferative stage of diffuse alveolar damage. The clinical response and physiologic parameters were evaluated during steroid therapy. Results : Five AIP patients received intravenous methylprednisolone (1-2 mg/kg every 6 hours) after $0.6{\pm}1.7$ days of mechanical ventilatory support. Lung biopsies were performed after $1.8{\pm}1.4$ days of mechanical ventilatory support. Four patients(80%) survived and were extubated after $2.8{\pm}0.4$ days of steroid therapy with improvement in the $PaO_2/FiO_2$ ratio ($127.4{\pm}10.0$ at day 0 to $223.8{\pm}37.6$ at day 7) by steroid therapy. However, one patient(20%) died of respiratory failure after 15 days of steroid therapy. Conclusion : Early steroid therapy sppears to be beneficial in AIP patients without evidence of infection. However, as our study group was too small, further large scale studies to define the effectiveness of steroids are required.
The human mind is a self-evolving system that develops along a multidimensional hierarchical pathway in response to traumatic stimulus. In absence of trauma, a mind integrated in conflict-free state is called monistic. When the monistic mind responses to a traumatic stimulus, a response polarity forms toward stimulus polarity within the mind, turning it into a bipartite structure. Dialectical interaction between the two opposites, originating from their incompatibility, creates a new third polarity in the upper dimension. Thereby, the mind turns into a trinity structure. When the interaction among the three polarities becomes optimized, the plasticity of the mind gets maximized into the "far-from-equilibrium state," and the function of three polarities is synchronized. Through this recalibration, the mind returns back to its monistic structure. If the mind with the recurred monistic structure responds to another traumatic stimulus, this cycle of hierarchical transformation repeats itself in this cyclical and fractal growth process through synchronization of basic trinity system. Applying this concept to the process of post-traumatic growth (PTG), this paper explores how the mind transforms traumatic experiences into PTG and proposes a 'PTG Clock' that shows a fundamental sequence in the development of the human mind. The PTG Clock consists of seven hierarchical phases, and each of the first six phases has two opposite sub-phases: shocked/numbed, feared/intrusive, paranoid/avoidant, obsessional/explosive, dependent/depressive, and meaningless/searching for meaning. The seventh, the synchronization phase, completes one cycle of the mind's transformation, realizing a grand trinity system, where the mind synchronizes its biological, social, and existential dimensions. At that point, the mind becomes more susceptible to not only the stimulus of its own traumatic experience but also the pain of others. Thereby, the PTG Clock sets out on a journey to another cycle of transformation in higher dimensions. The validity of this transformational process for the PTG Clock will be examined by comparing it to Horowitz's theory of stress response syndrome.
