It is well known non-drug therapy for hypertension patients can reduce blood pressure. These types of therapy include maintaining ones ideal body weight, quitting smoking, consuming large amounts of fruits and vegetables consuming low levels of saturated fat and salt and regular exercise. Fermented milk protein derived biologically active peptides such as isoleucine-proline-proline_(IPP) or valine-proline-proline_(VPP) have been shown to lower blood pressure in hypertensive subjects. This study was conducted to investigate the antihypertensive effects of medical nutritional therapy _(MNT) in accordance with the consumption of fermented milk enriched with IPP and VPP. To accomplish this, we conducted a randomized case-controlled study of 43 subjects who had blood pressure levels greater than 120/80 mmHg. The subjects in the study group were randomly allocated into two groups, an MNT + fermented milk (100mL/day) group (n=21) and an MNT+L. helveticus fermented milk with tripeptides (IPP=2.2mg, VPP=2.6mg/100mL) group (n=22). The MNT included weight management, reduction of sodium, total fat and saturated fat intake, increased intake of fruits and vegetables, and increased intake of low fat dairy products. The treatments were administered for 12 weeks during which time no drug interventions were conducted. The daily intakes of total calories, fats, cholesterol and Na decreased significantly after 12 weeks of MNT in the control and the experimental groups. In addition, the systolic blood pressure de creased significantly in the control and experimental groups; however, the diastolic blood pressure only decreased significantly in the experimental group. Overall, the results of this study indicate that the intake of fermented milk containing IPP and VPP in conjunction with MNT exerted positive effects on the blood pressure of pre- and hypertensive subjects.

Objective : The purpose of this research is to find clinical effects of application of weighted vest during task-oriented training focused on gross motor performance and balance abilities of children with spastic diplegia. Methods : 34 subjects were divided by simple random sampling into two groups; experimental group (male : 9, female : 8, average age : 8.12) and placebo group (male : 9, female : 9, average age : 7.53). Both two groups underwent to 40 minute intervention, twice a week for 12 weeks. The intervention was task-oriented training focused on facilitating closed kinematic chain and multi-joint functional movement pattern. During the training, the experimental group received loaded-resistance weighted vest and placebo group also received weighted vest but without loaded-resistance. Participants in both groups underwent 8 to 10 reps of the task-oriented training and there were 3 minutes break time between tasks. There were pre-test of gross motor performance and balance abilities, and two times of post-tests were performed upon 6 weeks and 12 weeks after the intervention completed. And in final, an additional follow-up test was performed 12 weeks after the evaluation was finished in order to find any difference between the two groups over time. Results : There was significant difference in Gross Motor Performance Measure (GMPM) between two groups. It is found that average score of the experimental group increased more than the placebo group after 6 weeks and 12 weeks intervention (p<.05). There was significant difference in Pediatric Berg's Balance Scale (PBS) between two groups. It is found that average score of the experimental group increased more than the placebo group after 6 weeks and 12 weeks intervention (p<.05). Conclusion : Based on the results in this study, it is proposed that application of weighted vest into task-oriented training to facilitating closed kinematic chain and multi-joint movement can improve gross motor performance and balance abilities of children with cerebral palsy.

Background: Despite widespread use of tracheostomy in intensive care unit, it is still controversial to define the best timing from endotracheal intubation to tracheostomy under prolonged mechanical ventilation. Early tracheostomy has an advantage of easy airway maintenance and enhanced patient mobility whereas a disadvantage in view of nosocomial infection and tracheal stenosis. However, there is a controversy about the proper timing of tracheostomy. Methods: We conducted a retrospective study of the 35 medical and 15 surgical ICU patients who had admitted to Ewha Womans University Mokdong Hospital from January 1996 to August 1998 with the observation of APACHE III score, occurrence of nosocomial infections, and clinical outcomes during 28 days from tracheostomy in terms of early (n=25) vs. late (n=25) tracheostomy. We defined the reference day of early and late tracheostomy as 7th day from intubation. Results: The number of patients were 25 each in early and late tracheostomy group. The mean age were $48{\pm}18$ years in early tracheostomy group and $63{\pm}17$ years in late tracheostomy group, showing younger in early tracheostomy group. The median duration of intubation prior to tracheostomy was 3 days and 13 days in early and late tracheostomy groups. Organs that caused primary problem were nervous system in 27 cases(54%), pulmonary 14(28%), cardiovascular 4(8%), gastrointestinal 4(8%) and genitourinary 1(2%) in the decreasing order. Prolonged ventilation was the most common reason for the purpose of tracheostomy in both groups. APACHE m scores at each time of intubation and tracheostomy were slightly higher in late tracheostomy group but not significant statistically. Day to day APACHE III scores were not different between two groups with observation upto 7th day after tracheostomy, Occurrence of nosocomial infections, weaning from mechanical ventilation, and mortality showed no significant difference between two groups with observation of 28 days from tracheostomy. The mortality was increased as the APACHE m score upto 7 days after tracheostomy increased, but there were no increment for the mortality in terms of the time of tracheostomy and the days of ventilator use before tracheostomy, Conclusion: The early tracheostomy seems to have no benefit with respect to severity of illness, nosocomial infection, duration of ventilatory support, and mortality. It suggests that the time of tracheostomy is better to be decided on clinical judgement in each case. And in near future, prospective, randomized case-control study is required to confirm these results.

To evaluate the efficacy and safety of red ginseng on women's health-related quality of life (QOL) and sexual function. A randomized, double-blind, placebo-controlled, crossover clinical study was performed. The main efficacy was measured using the Female Sexual Function Index (FSFl) and the 36-Item Short-Form Health Survey (SF-36). Twenty-four healthy, married women aged 30-45 years with FSFl scores below 25 were randomly divided into two groups: the red-ginseng group (N=12) and the placebo group (N=12). During the first six-week period (Study 1), each group was given red ginseng or placebo twice a day. Before the start of the second six-week period (Study 2), a crossover design was chosen with a two-week break (washout period). Interchanging the two groups after the washout period, red ginseng and placebo were given to each group. The outcomes were measured before and after each six-week period. Overall, 23 participants completed the study. In Study 1, the changes relative to the baseline in the FSFl total score were 22.50% and 22.99% for red ginseng and placebo, respectively. In Study 2, the relative changes were 8.14% for red ginseng and 6.29% for placebo. The results showed a greater improving trend in Study 1 with respect to all of the participants' sexual functions, but no significant difference was found between the groups (P=0.9567). After taking red ginseng, all the participants exhibited an improving trend in the desire domain of FSFl, but no significant difference was shown. In the measurement of SF-36, no significant difference was likewise shown. After taking red ginseng, though, all the participants exhibited an improving trend in the physical functioning (PF) domain of SF-36, with no significant difference. Moreover, there was no significant adverse event related to red ginseng. The QOL and sexual function of the study participants in the red-ginseng group were mostly improved, but no statistically significant effect of red ginseng was shown. It is supposed that this result was partly due to the affirmative impression of red ginseng in Korea. Thus, it is anticipated that a long-term clinical trial will show a significant effect of red ginseng on the QOL and sexual function.

Arrhythmias are common after cardiac surgery and are multifactorial. Intravenous magnesium administration reduces the frequency of ventricular arrhythmias in patient with symptomatic heart failure or acute myocardial infarction. This study was designed to evaluate the role of magnesium in preventing PVCs(premature ventricular contractions) occurred frequently after coronary artery bypass graft(CABG). 50 consecutive patients were prospectively entered into a randomized trial to determine the efficacy of postoperative magnesium therapy on the incidence of cardiac arrhythmias after elective coronary artery bypass graft. The patients underwent coronary angiography, echocardiography, electrocardiography and clinical laboratory study preoperatively. Continuous electrocardiographic monitoring was done and magnesium level was checked 0, 3, 6, 12, 18, 24, 36, 48, 60 and 72 hours postoperatively. Study group of 25 patients were given 4g of magnesium continuously over the first 24 hours and then 2g/24hours from 25 to 72 hours. The clinical characteristics of both groups were similar(p<0.05). The preoperative mean serum magnesium concentration was similar in both study group, 1.59mg/dl and control group, 1.71mg/dl. The mean postoperative serum magnesium concentration in study group elevated significantly over postoperative 12hours through 36hours(p<0.05). The postoperative mean serum magnesium concentration in control group declined and remained significantly depressed over immediate postoperation through 72hours. The mean serum magnesium concentration was significantly greater in the study group compared with the control group over postoperative 3hours through 72hours(p<0.05). There was a significant decrease in the incidence of arrhythmias such as PVCs(p<0.01) which might jeopardize hemodynamics. There were no recognized adverse effects of magnesium Administration. In conclusion, prophylactic magnesium administration seems to lessen the incidence and severity of rrhythmias after coponary artery bypass graft.

Purpose: The purpose of this randomized clinical trial is to determine whether implant length and the crown-to-implant (C/I) ratio influence implant stability and peri-implant marginal bone loss (MBL). Materials and Methods: 46 patients with single tooth missing in the posterior molar region of the mandible were included in this study. 19 implants (CMI IS-III $active^{(R)}$ long implant) of 5.0 mm diameter and 10 mm length were installed for the control group, while 27 implants (CMI IS-III $active^{(R)}$ short implant) of 5.5 mm diameter and 6.6, 7.3 or 8.5 mm length were placed for the experimental group. Each implant was inserted and immediately loaded using the digitally pre-fabricated surgical template and provisional restoration. The CAD-CAM monolithic zirconia crown was fabricated at 3 months after the surgery as a definitive restoration. The ISQ value and the MBL was measured at 48 weeks after the surgery. The correlation between the C/I ratio, MBL, and secondary implant stability was analyzed. Results: Successful results in terms of ISQ and MBL were achieved with both groups. There was no significant difference between the groups in terms of ISQ values and MBL at 48 weeks after the surgery (P > 0.05). No significant correlation was found between the C/I ratio and secondary stability as well as the C/I ratio and the MBL (P > 0.05). Conclusion: The influence of C/I ratio in both groups was not shown on the stability nor the marginal bone loss in implants supporting single crown of the mandible. Short implant could be a preferable alternative option in the reduced bone height mandible under the limited condition despite its higher C/I ratio.

Background : Erdosteine is a thiol derivative developed for the treatement of chronic obstructive bronchitis, including acute infective exacerbation of chronic bronchitis. Erdosteine has mucomodulating and antioxidant properties and especially exhibits excellent gastrointestinal tolerability. Methods : The study was conducted as a prospective evaluation, with 2 comparative groups orally treated with erdosteine 300mg (bid.) or ambroxol 30mg (b.i.d.) for 7 days and the design of trial was double-blind. The treatments have been assigned randomly to patients (n=80) with acute or chronic bronchitis. The primary end-point used to determine efficacy in this study was subjective symptoms including expectorating frequence, expectoration volume, expectorating difficulty, expectoration viscosity, cough intensity and dyspnea. The secondary end-points of efficacy was the result of arterial blood gas analysis and pulmonary function test. Safety was evaluated with adverse drug reactions and laboratory tests monitoring. 61 patients was included in the efficacy analysis, due to the fact that 19 patients drop-out for different reasons. The obtained values have been analyzed with paired Hest., ANOVA test., multivariate $t^2$-test, repeated measures analysis of covariance, two sample t-test, loglinear-logit model analysis, Fisher's exact test. Results : 1) There was no significant difference on demographic data and vital signs between erdosteine and ambroxol treated groups. 2) The comparison between erdosteine and ambroxol treated groups showed no significant difference in improvement of each symptom in spite of the more favorable efficacy obtained with erdosteine. No difference on the contrary was observed for arterial blood gas analysis and pulmonary function test. 3) As safety is concerned, no clinical significant changes in laboratory test and symptom were induced in erdosteine and ambroxol treated group and two patients in ambroxol treated group drop-out for adverse reactions in symptom. 4) In the evaluation of final clinical efficacy, erdosteine improved more effectively patient's overall symptoms {very good effect (11/31), good effect (12/31), moderate effect (6/31), no effect (2/31), aggravation (0/31)} than ambroxol {very good effect (6/30), good effect (14/30), moderate effect (5/30), no effect (4/30), aggravation (2/30)}. And the probability of symptomatic improvement by erdosteine compared to ambroxol was 2.5 times. (p<0.05). Conclusion : This study showed that erdosteine was clinically effective and safe drug for treatment of acute and chronic bronchitis.

Between August 1987 and July 1991, 22 patients with acute nonlymphocytic leukemia have received allogeneic bone marrow transplantation (BMT) with non-T-lymphocyte-depleted marrow obtained from matched sibling donors. Of these patients, 12 patients were in first complete remission (CR) and 10 patients in second CR or greater or in relapse. All patients were treated with a preparative regimen consisting of cyclophosphamide (CTX, 60 mg/kg) or combined drugs, and 850 cGy single-dose or $150\~200$ cGy fractionated total body irradiation (TBI) administered twice daily for a total dose of $1200\~1320$ cGy. Survivors have been followed from 8 to 64.5 months (median, 24 months). The overall 2 year survival rate, relapse rate and incidence of radiation pneumonitis and graft versus host disease (GVHD) have been evaluated by age, phase of disease, initial WBC count, modality of TBI or conditioning chemotherapy. Overall 2 year survival was $58{\%}$. The median survival was 31 months and mean survival was 23.2 months. Overall survival have significant impact in patients of age >19 years old (p=0.008), patients in first CR (p=0.09). Two year survival rate is significantly correlated with age ( >19 vs $\leqq$19, $79.4\%$ vs $14.3\%$, p=0.0008), regimen of chemotherapy (CTX vs combined drug, $76.9\%\;vs\;33.3\%$, p=0.04), phase of disease (1st CR vs \geqq2nd$ CR or relapse, $83.3\%\;vs\;30\%$, p=0.01) and method of TBI (fractionated vs single dose, $70.7\%\;vs\;37.5\%$, p=0.05). The influence of French-American-British (FAB) subtypes on relapse rate is not significant, but initial WBC count > 20000/$mm^3$ is associated with increased relapse rate. There is difference in the rate of radiation pneumonitis ($14.3\%\;vs\;25\%$), GVHD ($14.3\%\;vs\;50\%$) and relapse ($21.4\%\;vs\;50\%$) according to fractionated versus single-dose TBI. As mentioned above, fractionated TBI is compatible for the preparative regimen combined with chemotherapy En allogeneic BMT of first CR patients under 41 years of age with suitable donor. Those results from a retrospective, non-randomized study clearly need additional clinical data, ideally from a randomized study.

Background : Moxifloxacin is a newly developed drug which is more potent and safe compared to previous fluoroquinolones. This drug effectively eradicates organisms such as beta-lactamase-producing or other resistant bacteria. Moxifloxacin is known to be effective in treating respiratory infections such as Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Chlamydia pneumoniaeme, Legionella spp. and Mycoplasma pneumoniae. Methods : In a multicenter, randomized, open, comparative study, the efficacy and safety of oral moxifloxacin taken 400 mg once a day and clarithromycin taken 500 mg twice daily for 7 days were compared for the treatment of Korean patients with acute exacerbations of chronic bronchitis. Results : A total of 170 patients were enrolled, and they were divided into two groups: 87 in the moxifloxacin group and 83 in the clarithromycin group. Of those enrolled, 76 (35 for bacteriologic efficacy) in the moxifloxacin group and 77 (31 for bacteriologic efficacy) in the clarithromycin group were included in the efficacy analysis. All were included in the safety analysis. Clinical success was noted in 70 (92.1%) of 76 moxifloxacin-treated patients and 71 (92.2%) of 77 clarithromycin-treated patients. Bacteriologic success rate seemed to be higher in moxifloxacin group (73.5%) than in clarithromycin group (54.8%), but statistically insignificant (p=0.098). Drug susceptibility among organisms initially isolated was higher in moxifloxacin group on Streptococcus pneumoniae, Pseudomonas aeruginosa, Klebsiella pneumoniae (p<0.001). Adverse events were reported by 12.8% of 86 patients receiving moxifloxacin and 21.7% of 83 patients receiving clarithromycin. Headache (4.7% vs 4.8%, moxifloxacin group vs clarithromycin group, respectively) and indigestion (2.3% vs 6.0%, moxifloxacin group vs clarithromycin group, respectively) were the most frequent side effects in the two groups. Conclusion : This study demonstrated that for the treatment of acute exacerbations of chronic bronchitis a 7-day course of moxifloxacin 400 mg od was clinically equivalent and microbiologically superior to clarithromycin 500 mg bid.

Substantial alterations in cerebral blood flow(CBF) are known to occur during cardiopulmonary bypass(CPB). Many investigators have speculated that these changes may be responsible for both minor and major cerebral damages after CPB. More recently, these changes in CBF have been observed to be intimately related to the arterial carbon dioxide tension(Pa$CO_2$) maintained during CPB. The present study was prospectively designed to investigate the clinical effects of normocapnic and hypercapnic CPB on the cerebral oxygen metabolism in cardiac surgery Material and Method: Thirty-six adult patients scheduled for elective cardiac surgery were randomized to either normocapnic group (Pa$CO_2$35~40 mmHg, n＝18) or hypercapnic group(Pa$CO_2$, 45~55 mmHg, n＝18) with moderately hypothermic nonpulsatile CPB(nasopharyngeal temperature of 29~3$0^{\circ}C$). In each patient, middle cerebral artery blood flow velocity( $V_{MCA}$), cerebral arteriovenous oxygen content difference (C(a-v) $O_2$), cerebral oxygen extraction(COE), cerebral metabolic rate for oxygen(CMR $O_2$), cerebral oxygen transport( $T_{E}$ $O_2$), $T_{E}$ $O_2$/CMR $O_2$ ratio, cerebral desaturation(internal jugular bulb blood oxygen saturation $\leq$ 50%), and arterial and jugular bulb blood gas were evaluated throughout the operation. Postoperative neuropsychologic complications were assessed in all patients. All variables were compared between the two groups. Result: VMCA(169.13 $\pm$ 8.32 vs 153.11 $\pm$8.98%), TE $O_2$(1,911.17$\pm$250.14 vs 1,757.40$\pm$249.56), $T_{E}$ $O_2$,/CMR $O_2$ ratio(287.38$\pm$28.051 vs 246.77$\pm$25.84), $O_2$ tension in internal jugular bulb (41.66$\pm$9.19 vs 31.50$\pm$6.09 mmHg), and $O_2$saturation in internal jugular bulb(68.97$\pm$10.96 vs 58.12$\pm$12.11%) during CPB were significantly lower in normocapnic group(p＝0.03), whereas hypercapnic group had lower C(a-v) $O_2$(3.9$\pm$0.3 vs 4.9$\pm$0.3 mL/dL), COE(0.3$\pm$0.03 vs 0.4$\pm$0.03), CMR $O_2$(5.8 $\pm$0.5 vs 6.8$\pm$0.6), and arterial blood pH(7.36$\pm$0.09 vs 7.46$\pm$0.07, p＝0.04) during CPB. Hypercapnic group had lower incidence of cerebral desaturation than normocapnic group(3 vs 9 patients, p=0.03). Duration of the neuropsychologic complication(delirium) were shorter in hypercapnic group than in normocapnic group(36 vs 60 hrs, p＝0.009). Conclusion: These findings suggest that hypercapnic CPB may have salutary effects on the cerebral oxygen metabolism and postoperative neurologic outcomes in cardiac surgery.surgery.
