Objectives: The purpose of this research is to examine effects of acupuncture treatment on the autonomic nervous systems of Hwa-byung patients with insomnia. Methods: The study was performed through a patient-assessor blind, randomized, placebo-controlled trial in which the volunteers, data collectors, and analysts were unaware of which individuals were receiving the treatment. A total of thirty-seven volunteers were divided into 2 groups. Eighteen subjects were placed into a trial group and 19 subjects into a control group using a randomization table. The trial group was treated with bilateral Shigu, Ahnmyun, B62 (Shinmaek), and K6 (Chohae), while the control group was not given any other treatment. The ISI (Insomnia Severity Scale) was measured as the first evaluative instrument, and then a comparative analysis was conducted by comparing the results with those measured by ANS (BVP/HR, respiration rate, peripheral temperature, skin conductance, EMG). Results: In the BVP/HR, statistically significant decreases were found in those from the trial group compared to those of the control group. Skin conductance was found to be significantly increased in the trial group, as compared to the control group. However, there were no significant differences between the groups with respect to peripheral temperature, respiration rate, and EMG. Conclusions: The results suggest that acupuncture treatment is effective in the treatment of hwa-byung patients who suffer from insomnia due to their autonomic nervous systems.

Background: Venipuncture pain is an uncomfortable suffering to the patient. It creates anxiety, fear and dissatisfaction. The ketoprofen transdermal patch is a proven treatment for musculoskeletal and arthritic pain. We planned this study to evaluate the efficacy of the ketoprofen patch to reduce venipuncture pain. Methods: Two hundred adult patients, aged 18-60 years, of either sex, ASA grade I or II, were enrolled. Presuming that therapy would decrease venipuncture pain by 30%, a power calculation with ${\alpha}=0.05$ and ${\beta}=0.80$ required enrollment of at least 24 patients into each group. However, 100 patients in each group were recruited. Group I (Control) received a placebo patch; Group II (Ketoprofen) received a 20 mg ketoprofen patch. A selected vein on the dorsum of the patient's non-dominant hand was cannulated with 18 g intravenous cannula 1 h after the application of the respective patch. Assessment of pain was done by a 10 cm visual analogue scale (VAS) of 0-10, where 0 depicts "no pain" and 10 is "the worst imaginable pain". The venipuncture site was assessed for the presence of skin erythema, swelling and rashes at 12 h, 24 h and at the time of decannulation. Results: Incidence of pain was 100% (94/94) in the control group as compared to 93% (85/91) in the ketoprofen group. The severity of the venipuncture pain was 6 (2) and 2 (2) for control and ketoprofen groups respectively (P < 0.05). Conclusions: Application of a ketoprofen patch at the proposed site of venipuncture one hour before the attempt is effective and safe for attenuating venipuncture pain.

Background: The aim of our study was to evaluate the antiemetic effects of intravenous dexamethasone in preventing continuously infused epidural morphine-related nausea and vomiting. Methods: Twenty-seven patients requiring general anesthesia for gastrectomy were enrolled in a randomized, double-blinded, and placebo-controlled study. At the end of surgery, all patients received epidural morphine 3 mg and were connected to an epidural morphine infusion pump for 2 days in order to relieve postoperative pain. Before the morphine injection, the dexamethasone group (n = 12) received IV dexamethasone 10 mg, whereas the saline group (n = 15) received IV saline. The incidence of nausea & vomiting, pruritus, back pain and VAS scores were assessed in the recovery room, and at 24 h and 48 h postoperatively. Results: There was no significant difference in the total incidence of nausea and vomiting, pruritus, back pain or in the VAS scores. However, there was no vomiting and no back pain in the dexamethasone group. Conclusions: Intravenous dexamethasone did not significantly decrease the total incidence of nausea or vomiting in patients receiving continuous epidural morphine for postoperative pain control. However, IV dexamethasone appears to decrease the severity of nausea, vomiting and back pain.

This study was performed to investigate effects of examination-stress and protein supplementation on nitrogen metabolism and blood protein levels of Korean college students. Experiment was conducted at the beginning of a academic term and during midterm examination. During midterm examination, subjects were classified into two groups randomly : protein supplemental group(male n=6, female n=10) and placebo group(male n=4, female n=9). Protein capsules(2g/day) above 10% of indispensible amino acids requirement estimates were given to supplemental group for 10 days. At the begining of the term, male students(n=12) ingested 223.15mgN/kg/d, excreted 20.7mgN/kg/d in feces, and excreted 94.31mgN/kg/d in urine. Their apparent protein protein digestibility was 90.72%, true N balance was +100.11mgN/kg/d, and the mean maintenance N requirement of mixed Korena diet calculated was 112.13mgN/kg/d. Female students(n=19) ingested 171.44mgN/kg/d, excreted 22.13mgN/kg/d in feces, and excreted 122.92mgN/kg/d in urine. Their apparent protein digestibility was 86.76%, true N blance was + 18.39mgN/kg/d, and the mean maintenance N requirement calculated was 135.31mgN/kg/d. Blood levels of serum total protein, albumin, and BUN were within normal range. During midterm examination, fecal and urinary N excretions of female subjects(n=19) were increased, especially urea N markedly, and urea N/creatinine N ratio was augumented significantly. Apparent protein digestibility of male subjects(n=10) was decreased. Examination-stress showed 8.05mgN/kg/d (7.2%) increase of mean maintenance N requirement in male and 8.55mgN/kg/d(6.3%) increase in female students in comparison with that of the beginning of the term. Serum total protein and albumin levels showed no significant change, but serum transferrin level of female were decreased significantly. During midterm examination, females supplemented with protein capsules(2g/d)had no significant increase in fecal and urinary N excretions.

Amyloid ${\beta}-peptide\;(A{\beta})$ contributes to the pathogenesis of Alzheimer's disease (AD), causing neuronal death through apoptosis. In this study, the neuroprotective role of BF-7, extracted form sericultural product, was examined against $A{\beta}-induced$ toxicity in cultured human neuronal cell SKN-SH. In order to know if the BF-7 has positive role on the cognition and memory in human, the mixture of BF-7, DHA and EPA (BDE) was examined using Rey Kim and K-WAIS test with 50 healthy high school student. We report here that BDE significantly attenuated $A{\beta}-induced$ apoptosis through the reduction of ROS accumulation, and diminished caspase-like protease activity. Moreover, the memory index and memory preservation, and attentative concentration of BDE treated group for 1 month were significantly improved, in contrast to the case of placebo control treated with DHA and EPA. This result represent that the BF-7 play significant positive role on learning memory. Taken together, our result suggested the natural product BF-7 is a good substance for the brain functionally and physiologically.

The purpose of this study is to evaluate the reliability and effectiveness of hyperbaric oxygen chamber on alcohol-induced oxidative stress and hangover. In order to evaluate them, 20 healthy adults were tested for blood and hangover stress tests. When an exponential change was examined after 3 interventions (hangover drink, hyperbaric oxygen chamber, and normal chamber as placebo effect) of 1 hour, the heart rate of subjects experiencing a hyperbaric oxygen chamber showed a statistically significant decrease (p < 0.001). The tests of blood alcohol concentration (BAC) as for exquisite hematology analysis, glucose, creatinine, and AST (aspartate aminotransferase) as well as ALT (alanine aminotransferase) used as liver-damage indicator show that the hyperbaric chamber has the effective effect. In the test of lactic acid, CRP (c-reactive protein), cortisol, and creatinine, the hyperbaric chamber shows much more excellent effect than the hangover drink and normal chamber as control groups. Further studies on hyperbaric oxygen chamber intervention including this study could be very helpful for improving lives of both the patients and healthy people.

The purpose of this study was to investigate the effects of micronutrient supplementation on the growth of preschool children in China. A double-blind, placebo-controlled trial was conducted on 156 growth retarded preschool children who were randomly assigned to the following five groups : supplemental control (S-control; n=28); zinc supplementation (＋Zn; 3.5mg Zn/day, n=34); zinc and calcium supplementation (＋ZnCa; 3.5mg Zn ＋ 250mg Ca/day, n=37); zinc, calcium and vitamin A supplementation (＋ZnCaVA; 3.5mgZn ＋ 250mgCa ＋ 200gVA/day, n=28); and calcium and vitamin A supplementation (＋CaVA; 250mgCa ＋ 200gVA/day, n=29). Another 34 children of normal height were selected as a normal control (N-control). Supplementation continued for twelve months. After supplementation, the height gains in the ＋Zn group (7.84cm per year) and the ＋ZnCa group (7.70 cm per year) were significantly higher than that in the S-control group (6.74 cm per year, P＜0.05). The weight gain in the ＋ZnCaVA group (2.55kg per year) and the ＋CaVA group (2.57 kg per year) was also significantly higher than that in the S-control group (2.19 kg per year, P＜0.05). The average number of days of illness in each group taking supplements was lower than that in the S-control group (13 days per year compared with 23 days per year). No significant differences in bone maturity were observed between the groups. In conclusion, in this study Zinc and Zinc ＋ Calcium supplementation improved the height gain, and vitamin A improved the weight gain, in growth retarded preschool children, but these supplements did not affect the maturity of bone. Micronutrient supplementation also lowered the morbidity of these children.

The aim of this study was to investigate the effects of chicory fructan fiber supplementation on bone mineral density, apparent absorption of minerals and serum parameters related to bone turnover in postmenopausal women. Twenty-six healthy Korean postmenopausal women participated in the study. 1be participants were randomly divided into two groups in a double-blind parallel design and took one of the supplements for 3 months; either a placebo of 8g maltodextrins/sucrose mixture (control group) or 8g chicory fructan fiber (fructan group). During the 3-month experimental period no differences were found in bone mineral density (BMD) between the two groups. Apparent calcium absorption significantly increased by 42% in the fructan group, while that of the control group decreased by 29% as compared to the values at baseline. Urinary calcium excretion was not significantly different between the group;;. After 3 months, the level of serum alkaline phosphatase (ALP) was significantly lower in the fructan group than in the control group and deoxypyridinolin showed a trend toward a slight reduction. In conclusion, intake of chicory fructan fiber with a regular increases apparent calcium absorption in postmenopausal women.

To investigate whether BF-7, extracted from Bombyx mori, improved learning and memory of ordinary people, Rey-Kim Memory Test was performed with placebo group (32 persons), 200 mg BF-7 treated group (33 persons) and 400 mg BF-7 treated group (34 persons). BF-7 enhanced significantly learning and memory function in a dose-dependent manner. To know how BF-T plays such a positive role, we measured the concentration of acetylcholine in the brain from memory impairment animal model. Treatment of BF-7 significantly increased the concentration of acetylcholine. So, it is supposed that the protection of cholinergic neuron and/or keeping proper concentration of acetylcholine might be one of the mechanisms by which BF-7 improve brain function. So, our results suggest that the BF-7 is effective material for improving learning and memory ability.
