Controlled hypotension induced with sodium nitroprusside (SNP) has been most widely used to facilitate the surgical procedure and to reduce blood loss. However, major problem with its clinical use is cyanide toxicity, which is dose related. And resitance and tachyphylaxis, probably being mediated by sympathoadrenal response to lowered blood pressure, is known to increase dose requirements. Accordingly, several attempts have been made to attenuate sympathetic activity and therefore to reduce dose requirement of SNP. Verapamil, a representative calcium channel blocker, exerts inotropic and chronotropic effect, as well as vasodilation. And it is, also, known to impair pulmonary gas exchange. The purpose of these experiments was to evaluate hemodynamic and gas exchange effects of verapamil, and also its efficacy for reducing the amount of SNP during induced hypotension in patients anesthetized with isoflurane and N2O. Twenty five patients, scheduled to undergo general anesthesia with hypotension, were randomly assigned to two groups. Twelve patients were pretreated with verapamil (160mg, SOD: verapamil group) and the other thirteen were not (control group). The results were as follows: 1) Cardiac index remained unchanged in both groups and did not differ significantly between groups at all times. 2) Heart rate was significatly lower in verapamil group than in control group in the hypotensive period. (113+/- 3.3 vs 103+/- 2.7, p < 0.05) 3) Hypotension induced by SNP resulted from a marked decrease in systemic vascular resistance in both groups. 4) MPAP, PCWP, CVP, SVR and PVR significantly decreased after SNP infusion in both groups, but they did not differ significantly between the groups at all times. 5) SNP dose requirements to attain the same MAP reduction did not differ significantly between groups. (5.5+/-0.8vs 4.1+/-0.8mcg/kg/min, NS) 6) Verapamil pretreatment produced no significant change in intrapulmonary shunt fraction at all times. 7) SNP caused a signficant decrease in arterial oxygen tension in both group, but there were no significant difference between groups at all times. From the above results, it might be concluded 1) that verapamil, in clinical doses, does not blunt a reflex increase in sympathetic activity in response to SNP induced vasodilation, since it produced only a minor influence on SNP induced hemodynamics and the SNP dose requirements, and that verapamil does not inhibit hypoxic pulmonary vasoconstriction during isoflurane-N2O anesthesia. Thus, verapamil could not be a valuable adjunct of SNP in enhancing the hypotensive effect in spite of preserved arterial oxygenation.

We usually accept 1 : 1 ratio soft tissue change in mandibular set-back surgery. But we cannot sure whether we can use this ratio as a long term predictor after surgery. We investigated the change of hard tissue and its effects to soft tissue and examined the predictability of cephalometric analysis in short term and long term follow-up periods in mandibular set-back surgery. Subjects were 15 patients (5 male, 10 female) performed mandibular set-back procedure only by BSSRO with rigid fixation. Cephalometric data were obtained before orthodontic treatment, immediate before surgery and immediate after surgery, 6 months, and 18 months after surgery consecutively. Differences in soft and hard tissue changes among the time intervals were examined using analysis of variance (ANOVA) ; the association between immediate surgical change in chin landmarks and subsequent short and long term soft and hard tissue changes were examined using linear regression analysis 1. Soft tissue mandibular structures were positioned posteriorly and superiorly after surgery. Average mandibular set-back were 8.17mm at Pog. The horizontal and vertical hard tissue mandibular changes were stable for 18 months after surgery. Although there was a small degree of change, soft tissue and hard tissue remain relatively stable after surgery and there was no clinically discernable changes between 6 months and 18 months post-operatively. 2. Some part of upper lip (Ls & stms)and most part of mandibular soft tissue moves postero-superiorly after mandibular set-back. The ratio of horizontal changes of hard tissue to soft tissue at Inf. labial sulcus(B'), Pogonion(Pog') were 84.7%, 74.7% after 18 months. respectively. 3. Predictability of the soft tissue change is less certain than hard tissue and this predictability is decreased over time. These result suggests that we cannot predict the surgical outcomes exactly. It is recommendable that the oral surgeon should be careful in using the computerized surgical prediction software program as a predictor of long term soft tissue change.

BACKGROUND: To access the clinical usefulness of MicroScan(R) Synergies plus Combo Panels (Siemens, USA) for the identification and antimicrobial susceptibility test (AST) of Gram-negative bacteria (GNB) and Gram-positive cocci (GPC), we compared MicroScan(R) Synergies plus Combo Panels with MicroScan(R) conventional Combo Panels. METHODS: One-hundred four isolates of GNB were simultaneously tested with MicroScan(R) Synergies plus Neg Combo Type 2 Panel (SINC2) and MicroScan(R) Neg Combo Panel Type 44 (NC44). One-hundred isolates of GPC were simultaneously tested with MicroScan(R) Synergies plus Pos Combo 3 Panel (SIPC3) and MicroScan(R) Pos Combo 1A (PC1A). RESULTS: Of the GNB isolates, agreement rate of identification between SINC2 and NC44 were 92.3% to the species level and 93.3% to the genus level. Of the GPC isolates, agreement rate of identification between SIPC3 and PC1A were 85.0% to the species level and 100% to the genus level. Of the GNB isolates, agreement rate of AST according to antimicrobial agents between SINC2 and NC44 ranged from 86.5% to 100%. Among GPC isolates, agreement rate of AST according to antimicrobial agents between SIPC3 and PC1A were higher than 96.0% with the exception of gentamicin and quinupristin-dalfopristin. CONCLUSION: Compared with MicroScan(R) conventional Combo Panels (NC44, PC1A), MicroScan(R) Synergies plus Combo Panels (SINC2, SIPC3) showed high agreement rate of identification and AST, and had the advantage of more rapid reporting.

Background: Estrogen status is important for maintaining the homeostasis of bone. Estrogen has direct effects on bone cells, through binding to the high-affinity estrogen receptor. Several recent studies suggest that there might be genetically determined variations in biosynthesis and function of estrogen receptor in postmenopausal osteoporosis. Also the main cause of postmenopausal osteoporosis is decreased level of serum estrogen, whereas there had been some suggestion that the remaining estrogen have some effect on bone metabolism after menopause. We investigated the relationship between estrogen receptor gene PvulI polymorphism and bone mineral density(BMD), and the relationship between 18 urinary metabolites of estrogen and BMD in Korean postmeno- pausal osteoporosis. Methods: We examined the PvuII polymorphism of the estrogen receptor gene in 5' upstream region and the first intron by restrietion frapnent length polymorphism analysis in 62 postmeno- pausal wornen, BMD was measured by DEXA. The urinary estrogen metabolites were determined by GC/MS(Gas Chromatography-Mass Spectrometry) at Korean Institute of Science and Techno- logy Doping Control Center. Results: BMD of the spine and the femoral neck correlated with body weight, height, body mass index as we expected. There was no polymorphism of PvuII restriction site on 5 upstream region of estrogen receptor gene. Whereas the prevalen~ee of the PP, Pp, pp genotype in the first intron of estrogen receptor was 12.9%, 45.2%, 41.9%, respectively. But, there was no correlation between PvuII genotype and the spinel and femoral neck BMD. 2(OH)E2 among 18 urinary metabolites of estrogen, showed a negative correlation with the spinal and femoral neck BMD(r =-0.2551, p<0.05, and r =-0.3341, p<0.01, respectively), and the ratio of 16a(OH)E2/2(OH)E1> revealed a positive correlation with the spinal BMD(r =0.3057, p<0.05). In stepwise multiple regression analysis, body weight, 2(OH)E2, 16a(OH)E1, 2(Meo)E1 were independent predictors of the spinal bone density, and body weight and 2(OH)E2 were independent predictors of the femoral neck bone density. Conclusion: These results suggested that restrietion fragment length polymorphism analysis of the estrogen receptor gene with PvuII restriction enzyme was not helpful for early detection of patients at risk of developing osteoporosis. However, the ratio of 16-hydroxylation to 2-hydroxylation of estrogen metabolism was reduced in postmenopausal women and high catecholestrogen formation might be a greater risk factor for osteoporosis.

BACKGROUND: Positive correlations between bone mass and androgen levels have been observed in premenopausal and postmenopausal women as well as in men. Androgen production was decreased in women with osteoporosis compared to that in age-matched controls. We hypothesized that androgen metabolism might be also deranged in osteoporosis. To clarify our hypothesis, we investigated the relationship between urinary metabolites of androgen and bone mineral density (BMD) in Korean postmenopausal osteoporotics. METHODS: We examined the anthropometry and bone turnover marker in 67 postmenopausal women. BMD was measured by dual energy X-ray absorptiometry (DEXA). Serurn levels of estrone, estradiol, free testosterone were measured by radioirnmunoassay and serum level of sex hormone binding globulin (SHBG) was measured by two site immunoradiometric assay. The urinary metabolites of androgen were determined by gas chromatography-mass spectrometry (GC-MS) at Korean Institute of Science and Technology Doping Control Center. RESULTS: 1. Spinal BMD had a positive correlation with height (r 0.3049, p<0.05), weight (r=0.4114, p<0.001) and body mass index (BMI, r=0.2638, p<0,05). 2. Spinal and femoral neck BMD had no correlation with serum levels of estrone, estradiol and ten major urinary metabolites of androgen, but serum free testosterone had positive correlation with spinal BMD (r=0.3622, p<0.01) and SHBG had negative correlation with femoral neck BMD (r=-0.2625, p< (0.05). 3. Serum free testosterone in osteoporotics was lower than non-osteoporotics with spinal BMD (p<0.05) and SHBG in patients with osteopenia was higher than non-osteopenic subjects with femoral neck BMD (p <0.05). 4. In multiple stepwise regression analysis, weight and serum free testosterone were statistically significant for spinal BMD (R =0.3072). As for femoral neck BMD, weight was the independent determinant (R 0.1307). 5. Serum level of osteo#ealcin and urinary deoxypyridinoline/creatinine had a positive correlation with urinary 11-ketoandrosterone (p<0.05). SHBG was positive correlation with osteocalcin (r=0.3190, p<0.05). 6. Serum free testosterone (r=-0.2740, p<0.05) decreased with aging. CONCLUSION: Our data suggest that androgen metabolism is not deranged in osteoporotics, but serum free testosterone is important than estrogen on postmenopausal osteoporosis after 5-10 years menopause.

It is well known that moyamoya disease is often accompanied by an intracranial aneurysm. We present 3 patients, among total 40 patients with moyamoya disease over a recent 4-year period, in whom moyamoya disease and an intracranial saccular aneurysm were discovered simultaneously. In 2 of the 3 patients, the aneurysms were occluded endovascularly by Guglielmi detachable coils(GDC). Here, with review of pertinent literature, we discuss the clinical characteristics of an intracranial aneurysm associated with moyamoya disease and the benefits and drawbacks between two therapeutic options- direct surgery and endovascular treatment.

BACKGROUND: Standardization of medical terminology is essential for data transmission between health-care institutions or clinical laboratories and for maximizing the benefits of information technology. Purpose of our study was to standardize the medical terms used in the clinical laboratory, such as test names, units, terms used in result descriptions, etc. During the first year of the study, we developed a standard database of concept names for laboratory terms, which covered the terms used in government health care centers, their branch offices, and primary health care units. METHODS: Laboratory terms were collected from the electronic data interchange (EDI) codes from National Health Insurance Corporation (NHIC), Logical Observation Identifier Names and Codes (LOINC) database, community health centers and their branch offices, and clinical laboratories of representative university medical centers. For standard expression, we referred to the English-Korean/ Korean-English medical dictionary of Korean Medical Association and the rules for foreign language translation. Programs for mapping between LOINC DB and EDI code and for translating English to Korean were developed. RESULTS: A Korean standard laboratory terminology database containing six axial concept names such as components, property, time aspect, system (specimen), scale type, and method type was established for 7,508 test observations. Short names and a mapping table for EDI codes and Unified Medical Language System (UMLS) were added. Synonym tables for concept names, words used in the database, and six axial terms were prepared to make it easier to find the standard terminology with common terms used in the field of laboratory medicine. CONCLUSIONS: Here we report for the first time a Korean standard laboratory terminology database for test names, result description terms, result units covering most laboratory tests in primary healthcare centers.
