Objectives : Based on the changes of quality of life and pulmonary function test, we aimed to identify the effects and side-effects of Gamichuongsangboha-tang and in asthmatic patients. Methods : The subjects consisted of 30 patients with asthma who were treated with Gamichuongsangboha-tang extract for four weeks. Gamichuongsangboha-tang extract is the extracted powder form of the modified herbal decoction Chuongsangboha-whan, which has been used as the traditional therapeutic agent for asthma. Pulmonary function test (PFT) was checked before and after 4 weeks of treatment. Quality of Life QuestionnaireQ for Adult Korean Asthmatics (QLQAKA) was checked before and after 2 and 4 weeks of treatment. Unpleasant symptoms were checked in all patients at 2 weeks and 4 weeks from the beginning of treatment. Results : Treatment with Gamichuongsangboha-tang extract for four weeks resulted in significant increase in $FEV_{1.0}%$, PEFR%, and QLQAKA. The total efficacy rate of QLQAKA in the patient group was 53.3% after 4 weeks. The QLQAKA of the step 2, step 3, and step 4 groups (n=18, 55.6%) classified by global initiative for asthma (GINA) consistently increased, and significant improvement of QLQAKA occurred in the step3 group. In the step 4 group, FEV1.0%, and PEFR% were significantly increased. A total of 15 patients experienced unpleasant symptoms during the first 2 weeks of treatment, but these symptoms disappeared in all but 2 cases with no need of further treatment during the 2nd 2-week period. Conclusions : This study shows that Gamichuongsangboha-tang extract has effects on improvement of pulmonary function and quality of life, especially in persistent symptomatic asthmatics. Obviously further study concerning all these is still necessary.

This study was performed to investigate the effect of whole mandarin, peel or pulp intake of Citrus unshiu Marc. on antioxidative capacity and oxidative DNA damage in fifteen-month aged rats. Forty-eight male Sprague-Dawley rats $(621.9\;{\pm}\;10.1\;g)$ were blocked into four groups according to their body weights as control group, whole mandarin powder group, mandarin peel powder group and mandarin pulp powder group. Rats were raised with diets containing 5% (w/w) freeze dried mandarin formulations for four weeks. Total polyphenol content and total antioxidant status (TAS) of mandarin formulations were highest in peel powder, followed by whole powder and then pulp powder. The 8-hydroxy2'-deoxyguanosine concentrations of kidney in all mandarin groups were significantly lower than that of control group, and that of mandarin peel group was much lower than whole powder and pulp groups. Plasma TAS levels of all the experimental groups were higher than that of control group, and among mandarin groups, peel group showed higher level than remaining two groups. In conclusion, all the mandarin formulations were effective on antioxidative capacity in fifteen-month aged rats, and the peel was most effective one among three formulations.

Pure culture experiments were conducted to assess the bacteriostatic and bactericidal effects of phlorotannins (PT) isolated from Ascophyllum nodosum (brown seaweed) on Escherichia coli O157:H7. In Exp. 1, one non-O157:H7 strain (25922) and three strains of E. coli O157:H7 (3081, EDL933 and E318N) were cultured in M9 medium with PT included at 0 (control), 25, 50 or $100{\mu}g/ml$ (n = 3). Bacterial growth was monitored by $OD_{600}$ at 0, 4, 6, 12 and 24 h, and by dilution plating at 0, 4, 6 and 24 h. All strains were inhibited (p<0.001) by PT to varying degrees. At 50 or $100{\mu}g/ml$, PT prevented growth of all four strains. At $25{\mu}g\;PT/ml$, growth of 25922, 3081, E318N and EDL933 was inhibited for 6, 12 and 24 h, respectively, but 25922 and 3081 resumed growth by 12 and 24 h. Direct plating confirmed bactericidal effects of PT on all four strains at $100{\mu}g/ml$, and on EDL933 and E318N at $50{\mu}g/ml$. In Exp. 2, strains 25922 and 3081 were incubated with no tannins or with $50{\mu}g/ml$ of PT, purified condensed tannins (CT) from Quebracho (Schinopsis balansaei), or purified tannic acid from Rhus semialata (Anacardiaceae) as hydrolysable tannins (HT). Strain 3081 was unaffected by HT or CT, but was completely inhibited (p<0.001) by PT at 4, 6 and 24 h. Strain 25922 was unaffected by HT, slightly inhibited by CT, and almost eradicated by PT at 4 and 6 h. Transmission electron microscopy revealed tannin-mediated alterations to bacterial cell walls. Phlorotannins from A. nodosum exhibit growth-inhibiting and bactericidal effects in vitro against the strains of E. coli O157:H7 investigated. Anti-E. coli efficacy of A. nodosum PT is superior to that of terrestrial tannins purified from Quebracho and from Rhus semialata.

The present study was conducted to assess the dietary effect of T-2 toxin on the antioxidant systems of the liver in growing quail and to comparatively evaluate the protective properties of two different mycotoxin-adsorbent additives, Mycosorb and zeolite, in preventing inhibition of the antioxidant system. Four groups of 4 day old quail were formed with 20 birds in each group. The birds were maintained on the floor for the course of the study. The three treatment diets consisted of the basal diet with T-2 toxin added in the form of Fusarium sporotrichioides culture (8.1 mg/kg feed), T-2 toxin (8.1 mg/kg) plus zeolite (30 g/kg feed), and T-2 toxin (8.1 mg/kg) plus Mycosorb (1 g/kg feed). After 30 days of feeding (34 days old) all birds were sacrificed and liver samples for biochemical analyses were collected from five quail in each of the four groups. Antioxidant concentrations were evaluated by HPLC-based methods. Inclusion of T-2 toxin in the quail diet was associated with a significant (p<0.05) decrease in concentrations of all forms of antioxidants studied, including ${\alpha}$- and ${\gamma}$-tocopherols, ascorbic acid, retinol and retinyl esters. At the same time, liver susceptibility to lipid peroxidation significantly (p<0.05) increased. Inclusion of zeolite in the quail diet at the level of 3% was ineffective in preventing antioxidant depletion in the liver by mycotoxicosis. In contrast, Mycosorb in the diet at a 0.1% level was able to significantly inhibit liver antioxidant depletion and as a result decreased lipid peroxidation in the liver. Concentrations of all forms of antioxidants studied were significantly higher in the livers of the quails fed the basal and T-2 toxin/Mycosorb combination in comparison to birds fed the basal with T-2 toxin alone.

Introduction: This study examined the effect of autogenous tooth bone used as a graft material for bone regeneration in an artificial bony defect of minipigs. Materials and Methods: Four healthy minipigs, weighing approximately 35-40 kg, were used. Four standardized artificial two-walled bony defects, 5 mm in length and depth, were made on the bilateral partial edentulous alveolar ridge on the mandible of minipigs, and autogenous tooth bone was augmented in the right side as the experimental group. On the other hand, only alloplastic bone graft material HA was grafted with the same size and manner in the left side as the control group. All minipigs were sacrificed at 4 weeks after a bone graft and evaluated histologically by Haematoxylin-eosin staining. The specimens were also evaluated semi-quantitatively via a histomorphometric study. The percentage of new bone over the total area was evaluated using digital software for an area calculation. Results: All specimens were available but one in the left side (control group) and two in the right side (experimental group) were missing during specimen preparation. The amount of bone formation and remodeling were higher in all experimental groups than the control. The mean percentage area for new bone in the experimental and control groups was $43.74{\pm}11.96%$ and $30.79{\pm}2.93%$, respectively. Conclusion: Autogenous tooth bone is a good alternative to autogenous bone with the possible clinical feasibility of an autogenous tooth bone graft in the reconstruction of bony defects.

The objects of this experiment was to investigate the effect of dietary several supplemental probiotics on performance and intestinal microflora of Lohmann brown laying hens from 68 to 80 weeks. Basal diets based on corn and soybean meal contained 18.0% CP and 2,720㎉/kg ME. Bacillus subtilis, Lactobacillus salvarius isolated from piglet(LSP) were fed at the level of 0.1 and 0.2% in a one way design. There were four replicates of 40 hens each per treatment. Egg production, feed intake, feed conversion ratio(FCR), eggshell quality were measured at every four weeks and intestinal microflora were examined at the end of experiment. Egg production of bird fed 0.2% individual probiotics was significantly higher than that of control(P 0.05). Birds fed the diet containing 0.2% LSC and LSP had significantly lower FCR than other treatments(P 0.05). However, egg weight of birds fed control and 0.2% BS diet showed higher than other treatments. Feed intake of 0.2% BS and 0.1% LSP treatment was significantly higher than other treatments, but was not consistency of all treatments(P 0.05). Eggshell breaking strength and thickness of hens fed probiotics tended to increase compared to that of control, but was not significantly different. Intestinal anaerobes, Lactobacillus spp. and yeast of hens fed all tested probiotics were significantly increased compared to those of control. The number of intestinal E. coli of all probiotics treatments except 0.1% LSP tended to decrease. Intestinal Lactobacillus spp. was increased significantly by 0.1% dietary LSC, whereas intestinal yeast showed significant increase in LSP treatments(P〈0.05). The results of this experiment indicated that feeding probiotics to laying hens improved the egg production, FCR and increased beneficial microflora.

Background: The authors conducted a retrospective study to evaluate the mechanism of injury, the surgical techniques, the clinical features, the combined injuries, the treatment results, and the surgical complications in patients with atlantoaxial fracture/subluxations. Methods: The authors reviewed 71 cervical fracture/dislocations during a four-year period from September 2002 to August 2006. Among them, there were twenty one C1,2 fracture/subluxations. There were thirteen men (mean age : 43.5 years) and eight women (mean age : 50 years). Their follow-up period was at least 6 months, and the mean follow-up period was 9.6 months. Gardner-Wells tongs traction was used in all patients immediately on presentation. Surgical treatment was performed, depending on the pathologic conditions. Results: Of all 21 cases, 14 cases were injured in motor vehicle accidents, 5 were falls, and 2 were miscellaneous. There were four C1 fracture (5.6%), fourteen C2 fracture (66.7%), one C1 and 2 combined fracture (4.8%), and one C1-2 subluxation (4.8%). The C1 fractures in our series were classified as two Jefferson's fractures and two C1 lateral mass fracture. The C2 fractures were classified as one odontoid type I fracture, two odontoid type II fractures, five odontoid type III fractures, one hangman's fracture, and four C2 body tear-drop fractures. Atlantoaxial fractures were associated with six (28.6%) head injuries, four (19.0%) other spinal injuries, two (9.5%) chest injuries, and three (14.3%) spinal cord injuries. Surgical treatment was performed in nine cases, which included anterior odontoid screw fixation in two cases, transarticular screw fixation with iliac bone graft in one case, posterior fixation by using C2 pedicle screw and C3 lateral mass screw in three cases, lateral mass screw fixation C1-2 with iliac bone graft in one case, O(occipito)-C1-3-4 screw fixation in one case, posterior C2-3 wiring with allograft in one case, and halo vest in six cases. Conservative management was used in the rest of the patients in our trials. Bone fusion was complete in all cases. There were no operation-related complication, except one pin site infection in the case of halo vest. Conclusion: In this study, the choice of appropriate treatment according to the fracture types resulted in safe and effective management of unique atlantoaxial fracture/subluxations.

The purpose of the present study is to evaluate dimensional consistency, bristle finishes and bristle rebound rate of four brands of $Dentichek^{(R)}$ toothbrushes(regular-male, regular-female, soft-male, soft-female) to provide referneces in product enhancement and quality control for the manufacturer and to provide suggestions in selecting appropriate toothbrushes for general public. The results are as follows : 1. The size of the head is : $25.10{\times}8.10mm$ for male toothbrushes and $19.90{\times}8.10mm$ for male toothbrushes, while the size of the bristle portion is: $29.90{\times}10.65mm$ for male toothbrushes and $25.25{\times}10.65mm$ for female toothbrushes. 2. The length of the bristles is 10.70mm in all four groups. 3. The length of the toothbrush is 192mm in all four groups. 4. The number of tuft is 43 for male toothbrushes and 35 for female toothbrushes. Tuft arrangement is 4-row configuration in all four groups. 5. The number of bristles in a tuft ranges from 40-56, with higher numbers in male toothbrushes compared to the female counterparts, and higher numbers in the "soft" variety compared to the regular ones. 6. The diameter of the bristle is : 0.21mm for the outer row and 0.19mm for the inner row in the regular brand, and 0.17mm for the soft brand. 7. Irregularly finished bristle ends comprised 20-22% of the total bristles. 8. The bristle rebound rate ranges from 55.9% to 62.3%, with higher numbers in the "soft" variety compared to the regular ones. The above results show that $Dentichek^{(R)}$ toothbrushes meet the requirements of Korean Dental Association standards for toothbrushes, but further evaluations of their effects on periodontium and plaque elimination in actual in-use situation may be needed.

This study was performed to investigate the effect of chamomile, sage, and green tea intakes on anti oxidative capacity in 15-month-old rats. Dried powders of three plants were analyzed to determine the amount of total flavonoids, $\beta$-carotene, vitamin C, vitamin E, and dietary fibers. In order to examine the change of antioxidative capacity in old rats, forty-eight Sprague-Dawley male rats weighing 621.2$\pm$9.5 g were divided into four groups according to body weight and fed for four weeks with each experimental diet of three dried powders and control diet. Plasma and liver thiobarbituric acid reactive substances (TBARS) levels and xanthine oxidase (XO) activities, erythrocyte and liver superoxide dismutase (SOD) activities and plasma vitamin A, C, E, and total carotenoids levels were measured. The total flavonoids and vitamin C contents were the highest in green tea powder. Beta-carotene and vitamin E contents were not significantly different among all three dried powders. Total dietary fiber contents also were not different among all three dried powders, but soluble dietary fiber contents of chamomile was higher than other two dried powders. Plasma TBARS level was found to be significantly lower in all the experimental groups as compared to control group. Chamomile powder group, especially, showed the lowest level among all experimental groups. Liver TBARS levels of experimental groups were also lower than that of control group and significant differences were observed in chamomile and green tea groups compared to control. Plasma XO activity of green tea group was significantly lower than control group. Liver XO activities of green tea and chamomile groups were significantly lower than control group. Erythrocyte SOD activity was not significantly different among all the groups. However, liver SOD activities of sage and green tea groups showed a significant increase as compared to control group. Plasma vitamin A level was not significantly different among all the groups. Plasma total carotenoids levels were found to be significantly higher in experimental groups as compared to control group. Plasma vitamin E level of chamomile group and vitamin C level of green tea group showed the highest level among all the groups. In conclusion, chamomile, sage, and green tea intakes had an effect on improving antioxidative capacity in 15-month-old rats. Effects of green tea and chamomile powders, especially, were higher than sage powder.

Purpose: In hand injury, pedicle is usually damaged by avulsion injury or crushing injury. Because of postoperative pedicle obliteration, it is often hard to save the injured hand and fingers, even after successful replantation. The author introduces three cases of extensive hand injury, and successful results after applicatoin of multiple venous grafts to these patients. Methods: In all cases there was no circulation in any finger. In the first case, some vessels were extracted, so venous graft was applied to two sites of severely damaged venous sites. In the second case, venous grafts were applied to all four digital arteries of all fingers except thumb which got severely crushed, and two sites of dorsal veins. In the third case, venous graft was applied to all four digital arteries of all five fingers, and two sites of dorsal veins and palmar veins each. Results: In all cases, survival of hands and fingers was successful. In the second case, however, amputation in thumb and little finger at DIP joint level was inevitable, because of its severe damage, and the large dorsal defect on index finger was filled with DIEP free flap. Thumb was reconstructed with toe-to-thumb free flap, and additional debulking procedures and contracture release is furtherly needed. In the first case, additional surgery was done, as FDP tendon got re-ruptured, but in long term follow-up, satisfactory range of motion was attained. In the third case, FTSG on dorsal skin region was planned. as flap on dorsal area got partial necrosis. Conclusion: In hand injury, there are many structures to be repaired, but sometimes venous graft is avoided for its long operating time. Even though the length of damaged vessel is enough for anastomosis, the endothelium is often damaged (zone of injury). In extensive hand injury, successful reconstruction would be possible with active venous graft to all vessels suspicious for damage.
