Sixty patients, of ASA physical status class I for elective operations in the lower abdomen, perineum, or lower extremities, were studied in a comparative prospective trial to evaluate the efficacy of epidural morphine and ketamine for postoperative analgesia. They were divided into two groups: an epidural morphine sulfate group (EMS group; 30 patients), and an epidural ketamine hydrochloride group (EKH group; 30 patients). Indwelling epidural catheters were placed in the patients' lumber areas (L3-4) and then all patients were anesthetized with thiopental, nitrous oxide, and halothane. After the patients had fully recovered from the anesthesia, the analgesic agents were administered epidurally via the catheter when the patients complained of pain in the postoperative period. The groups were given either 0.1 mg/kg of morphine sulfate or 0.5 mg/kg of ketamine hydrochloride administered in a volume of 10 ml of normal saline. Patients were observed for the onset and duration of postoperative analgesia and for other effects. Total doses were $5.7{\pm}0.6\;mg$ of morphine sulfate in the EMS group and $27.9{\pm}3.3\;mg$ of ketamine hydrochloride in the EKH group. The onset of analgesia was detectable within 35 min.($23.5{\pm}6.3$ min) in 86.7% (26 cases) of the EMS group and within 10 min. ($7.8{\pm}3.7$ min.) in 76.7% (23 cases) of the EKH group. Mean duration of postoperative analgesia was $22.3{\pm}2.1\;hr$. in the EMS group. In the EKH group, the duration of analgesia was shorter and variable, the range of duration was from 2 hr. to 24 hr., Cardiopulmonary changes were statistically insignificant ih both groups. Side effects such as nausea, vomiting, urinary retention, pruritus, dizziness, and headache were observed in EMS group. In the EKH group, there was no discomfort except dizziness (3 cases) and headache (1 case). Epidural ketamine was a safe technique for postoperative analgesia, but because of the variability and relative shortness in the duration of analgesia the use of this technique will require further clinical trials.

The purpose of this study was to examine the needs of dental hygiene students at a lifelong education center of a three-year-course college for a credit bank system. The subjects in this study were 200 dental hygiene students at a college located in J, which offered courses of a credit bank system. A survey was conducted from May 19 to 23, 2008, to gather data on the acquisition of a bachelor's degree and the credit bank system, and the answer sheets from 184 respondents(92%) were collected. After the collected data were analyzed with SPSS/WIN 12.0 program, the following findings were given: 1. In regard to an intention of taking a bachelor's degree, the largest number of the students investigated(74.5%) intended to do that if they had any chance. As for the reason, 55.6% wanted to get the degree in pursuit of their own personal development. 2. Concerning how to win a bachelor's degree, the largest group that accounted for 63.0% preferred the credit bank systems of college lifelong education centers. 41.8% got interested in the credit bank system mainly because their acquaintances informed them of it. It shows that colleges should reinforce publicity activities if they want to offer the credit bank system. 3. The quality of educational programs and cost had an impact on the choice of an educational institution when they planned to get a bachelor's degree from the credit bank system. Therefore excellent educational programs should be provided, and the government should provide learners with economic help and fund educational institutions. 4. As to comparison of a regular college and the credit bank system as a way to get a bachelor's degree, that was considered to be helpful for finding a job(a mean of 3.39) and for the development of sociability(3.22). That was also deemed to be of use for the improvement of practical job performance, to win public recognition and to be helpful for being well-cultivated, though not many students had those opinions. They took a different view according to academic year(p<.05). 5. Regarding the expected effects of getting a degree from the credit bank system, the greatest group expected it to step up their personal development(3.85). The second largest group expected it to boost job efficacy(3.30), and the students whose academic year was higher had a better opinion. 6. As for future directions for the credit bank system, the largest group put emphasis on the improvement of social perception through intensive P.R. and the enhancement of the qualifications of professors and lecturers(4.02). These opinions were more stressed by the juniors than by the sophomores and seniors, and academic year made a significant difference to their views(p<.05).

Objectives: This study was conducted to help clinical studies for treating Functional Dyspepsia with acupuncture. We inspected tendency of studies of acupuncture treatment for functional dyspepsia and analyzed the assessing instrument for it by scrutinizing Pubmed recent publications. Materials and Methods: We inspected 8 theses and scrutinized their objectives, periods, participants, materials and methods, the instrument of assessment for the studies, and criteria and symptom score for questionaire, results and JADAD score. Results: 1. Most studies were published by oriental doctors except one which was published by an American doctor. More and more studies are being published in America and written in English recently. So it is considered that western doctors think that the acupuncture treatment is useful as unorthodox medicine for functional dyspepsia. 2. Among the 4 clinical studies, 2 studies were RCT and 1 study was not RCT and 1 study with vagueness. All 4 clinical studies were not double-blinded because they were about comparison between acupuncture treatment and medicine. 3. ST36, PC6, CV12, BL21 were chiefly used, and auricular point, ST40, SP6 were also used. Manual acupuncture were used in 2 studies, and low frequency pulse and electroacupuncture were used in other studies respectively. 4. 4 clinical studies used 0~3 points symptom score as the instrument of assessment. Additional assessments were on gastric emptying time, EGG and plasma level of motilin. All thesis were not verified of validity and reliability. 5. Among the 4 reviewed thesis, 2 theses were about acupuncture as one of the various treatment of functional dyspepsia, and the other 2 theses were about efficacy of acupuncture treatment. And the result generally showed effectivity of acupuncture treatment. Conclusion: Acupuncture treatment for functional dyspepsia is considered useful as in unorthodox medicine by western doctors, and it is necessary to provide objective instrument for assessing acupuncture treatment for functional dyspepsia.

It is well known that sunflower (SF) sprout has more beneficial effects than SF seed due to increased levels of phytochemical components such as vitamins, total phenolics, and isoflavones during germination. This study investigated the physicochemical properties and antioxidative activities of SF seed during both germination and cultivation. In a proximate analysis, the water content of SF groat was 9.17% and then increased to 15.32% on the 11th day after seeding. On a dry weight basis, crude fat content decreased while the contents of carbohydrates, crude protein, and crude ash increased. As cultivation proceeded, the contents of minerals were in decreasing order of K, Mg, Ca, Na, Zn, Fe, Mn, and Cu, in which SF sprout cultivated for 9 or 11 days contained the highest mineral contents. Though vitamin C was not detected on SF groat, the content of vitamin C continuously increased up to the 5th day of cultivation and then decreased gradually. Vitamin E content in SF groat was higher than that in SF sprout. It was also found that the vitamin E content in SF sprout was the highest on the 5th day of cultivation. Daidzin was not detected in SF groat, but its concentration reached a maximum on the 5th day of cultivation in SF sprouts. Furthermore, higher amounts of daidzein were observed on the 3rd, 5th, and 9th days of cultivation. The highest total isoflavone content was observed on either the 3rd or 5th day of cultivation. The highest content of total phenolics was observed on the 5th of cultivation. When DPPH radical and peroxyl radical scavenging activities of SF sprout were measured in order to measure antioxidant efficacy, it was found that 5 day-cultivated SF sprout had the highest scavenging activities. In conclusion, SF sprout cultivated for 9 or 11 days was found to be a good source of minerals. Furthermore, the fifth-day after seeding was the optimal time for the production of SF sprout with effective natural antioxidant activity and high amounts of functional components such as vitamins, total phenolics, and isoflavones.

Purpose To evaluate the safety and efficacy of stent-assisted coil embolization (SAC) in acutely ruptured cerebral aneurysms without severe symptoms, and thus, the usefulness of the stent itself in patients with subarachnoid hemorrhages. Materials and Methods From January 2017 to June 2019, 118 patients were treated with coil embolization for acutely ruptured cerebral aneurysms without severe symptoms (Hunt & Hess grade ≤ 3). The periprocedural complications, six-month modified Rankin scores (mRS), and six-month radiologic outcomes were compared between 56 patients with SAC and 62 patients without SAC (non-SAC). Results The rate of good clinical outcomes (mRS ≤ 2), as well as the rate of hemorrhagic and ischemic complications, showed no significant difference between the SAC and non-SAC groups. Moreover, compared to the non-SAC group, the SAC group showed a lower recanalization rate on the six-month follow-up angiogram (20% vs. 39.3%, p = 0.001). Conclusion Although stent use was not significantly associated with clinical outcomes in coil embolization of ruptured cerebral aneurysms with non-severe symptoms (Hunt & Hess grade ≤ 3), it significantly decreased the rate of recanalization on follow-up cerebral angiograms.

Recently, several alternatives have been attempted in the management of benign prostatic hyperplasia (BPH) to reduce morbidity of traditional transurethral resection of the prostate (TURP). Among new modalities, transurethral electrovaporization (TEVP) is considered as a promising alternative. To evaluate the safety and initial efficacy of JEVP using the roller loop electrode (ProSurg Inc. USA) on BPH patients, we compared the results of TEVP with those of TURP and visual laser ablation of the prostate (VLAP). In this study, a total of 115 patients with symptomatic BPH were underwent TEVP (n=17), TURP (n=59) or VLAP (n=39) since 1995. Before treatment, patients were evaluated with an International Prostate Symptom Score (IPSS) and the measurement of maximal uroflow rate (MFR) and postvoid residual urine (PVR). After treatment, the operative and hospital records were reviewed. The uroflowmetry and IPSS were re-evaluated 3-10 months after treatment. In clinical outcome of re-evaluation compared to the preoperative parameters, there was a clinically significant improvement in three procedures. TEVP resulted in 62% reduction in IPSS (TURP, 73% : VLAP, 69%), 84% improvement in MFR (TURP, 113% : VLAP, 91%), and 74% reduction in PVR (TURP, 88% : VLAP, 78%). TEVP had shorter duration of hospitalization and catheterization than the others. TEVP was associated with lower rates of treatment-related complication than TURP. In conclusions, TEVP is considered as a useful procedure to treat symptomatic BPH. And, the advantages of TEVP over TURP include excellent intraoperative hemostasis, lower morbidity, shorter hospital stay and simple technique. In addition the advantages over VLAP include lower cost, shorter duration of catheterization and early symptom improvement.

Three experiments were conducted to investigate the interaction of breed-by-chitosan supplementation on the major economic traits in broiler chickens. In experiment 1, one-day-old broiler chicks were fed ad libitum on a basal diet (CON-group) or basal diet containing chitosan at an inclusion level of 10.5 mg/bird/day (EXP-group). The EXP-group birds in experiments 2 and 3 were supplemented from 15 day-old by the same amount of chitosan used in experiment 1. In experiment 1, the mean body weight of the EXP-group chickens was significantly (p<0.05) heavier in comparison with those of CON-group birds from day 21 of the experiment. Especially in 35 day-old mean body weight, the EXP-group birds of Arbor Acres, Peterson, and Ross were significantly (p<0.05) heavier by 121.8 g, 118.5 g, and 242.8 g than the CON-group birds, respectively. However, the mean body weights in experiments 2 and 3 did not significantly differ between the CON-group birds and the EXP-group birds fed with chitosan supplementation from day 15 post birth. In the comparisons among breeds on the mean body weight at 35 day-old, the birds of Arbor Acres were significantly (p<0.05) heavier than ones of Peterson or Ross; however, there were no significant differences between Peterson and Ross or Cobb and Ross birds in overall in the experiments. The mean 15-35 d FCR of the EXP-group birds in experiment 1 were significantly (p<0.05) lower at least in two of the three breeds (Arbor Acres and Ross breeds) than that of the CON-group birds. None of the mean 15-35 d FCR in either experiment 2 or 3 showed significant differences between groups within a breed. In all three experiments, the differences amongst breeds in the mean 15-35 d FCR were not great either. Significant differences were not generally shown in the mean percentage of abdominal fat deposition between groups within a breed in overall experiments except in the Cobb breed in experiment 3. The mean percentages of abdominal fat deposition were significantly (p<0.05) lower in Ross birds than in Arbor Acres or Peterson birds and in Cobb birds than in Ross birds. By the results of the analysis of variance, the interaction of breed-by-diet (chitosan) supplementation on any of the major economic traits including mean percentage of abdominal fat deposition was not significant in overall experiments. Results of these experiments indicate that dietary supplementation with chitosan for the improvement of growth or feed conversion ratio in broilers has an efficacy when the supplementation begins from day-old.

For human organ transplantations, histidine-tryptophan-ketoglutarate solution (HTKS) and University of Wisconsin solution (UWS) have been shown to engender similar outcomes as gold standard cold preservation solutions ($4^{\circ}C$). To select the effective preservation solution for cold storage of kidney xenografts in miniature pig, which could be a potential source animal of bio-organs, this study compared early histopathological outcomes of cold preservation injury using HTKS and UWS. Twelve miniature pigs weighing 25.6 to 34.7 kg were divided into two groups (n = 6 per group), UWS group and HTKS group. The kidneys in each group were harvested, cold flushed, and preserved for 0, 24, 48, and 72 hrs at $4^{\circ}C$ with UWS or HTKS, respectively. Histolopathological examinations were assessed on kidney biopsy specimens, taken after each cold storage. The degree of renal injury was scored using 5 different criteria (pyknotic nuclei, disruption of cytoplasm, detachment of epithelium, loss of microvilli, tubular necrosis and loss of glomerular tufts) of the cellular components of the tissue. The degree of kidney damage was increased with prolonged cold ischemia time. UWS and HTKS have at least similar efficacy in kidney preservation within 24 hrs cold preservation time. However, in HTKS group cold-induced injury started to be observed more than in UWS group after 48 hrs of cold storage. In conclusion, UWS and HTKS were equally effective for cold preservation of miniature pig kidney in early preservation times; however, UWS may be more effective at longer preservation times as compared to HTKS.

The objective of this study was to evaluate the effect of the different types and levels of prebiotics on intestinal microflora and fermentation products in the in vitro fermentation model. The prebiotcs used in this study were IMO (iso-malto oligosaccharide), CI (partially digested chicory-inulin), RA (raffinose) and CD (cyclodextrin). Experimental diet for growing pigs was predigested by digestive enzymes and this hydrolyzed diet was mixed with buffer solution containing 5% fresh swine feces. Then, the mixture was fermented with or without prebiotics at the concentrations of 0.5 and 1.0% for 24 h. Samples were taken at 24 h, and viable count of micoflora, gas, pH, volatile organic compounds and short-chain fatty acids were determined. The viable count of Enterobacteriaceae was significantly decreased (p<0.001) in all treatments added with prebiotics in comparison to control without prebiotics. However, the increase of lactic acid bacteria was observed in the prebiotics treatment. Gas production increased as the level of prebiotics increased. The pH values in the fermentation fluid decreased in a dose-dependent manner with increasing the concentration of prebiotics. The fermentation with prebiotics resulted in the reduction of malodorous compounds such as ammonia, hydrogen sulfide, indole and skatole. The increase in short-chain fatty acid (SCFA) production was observed in the treatments with prebiotics. In conclusion, the results of this study demonstrated that the fermentation with prebiotics was effective in reducing the formation of malodorous compounds and increasing lactic acid bacteria and SCFA. These effects depended on the concentration of prebiotics. Moreover, further study is needed to determine whether the in vitro efficacy on the reduction of malodorous compounds and increase of SCFA would also be observed in animals.

Background: Invasive aspergillosis (IA) is associated with high morbidity and mortality, particularly among immunocompromised patients, such as lung transplant recipients. Voriconazole, the first-line therapy for IA, shows a non-linear pharmacokinetic profile and has a narrow therapeutic range. Careful and appropriate administration is necessary, primarily because it is used for critically ill patients; however, the clinical usefulness of therapeutic drug monitoring (TDM) has not been sufficiently verified. Therefore, in this study, we validated the safety and efficacy of voriconazole TDM in lung transplant recipients receiving only voriconazole for IA treatment. Methods: The electronic medical records of lung transplant recipients (${\geq}19$ years of age) administered only voriconazole for > 7 days for treatment of IA from June 1, 2013 to May 31, 2018 were analyzed retrospectively. Results: Among the 54 patients, 27 each were allocated to TDM and non-TDM groups, respectively. There were no significant differences in patient characteristics between the two groups except for ICU-hospitalization status. Of the TDM group patients, 81.5% needed adjustment of voriconazole dosage because the levels were out of target range. Comparison of two groups showed that treatment response was higher throughout treatment and switching rates of second-line agents were significantly lower in the TDM group, but it was insufficient to confirm safety improvements through voriconazole TDM. Conclusions: Considering that the treatment response tended to be higher and the rates of switching to second-line antifungal agents were lower in the TDM group, voriconazole TDM may increase the therapeutic effect on IA in lung transplant patients.
