Objective : The purposes of this study are to evaluate the efficacy of Bee Venom therapy(BV) on HNP(Herniation of Nucleus Purposus) of Lumbar spine by use of Visual Analog Scale(VAS), Pain Rating Scale(PRS) and Digital Infrared Thermographic Imaging(DITI), and to investigate their correlation. Methods : We researched 20 patients who were diagnosed by MRI as having a HNP, and treated them by Oriental medical therapy(including BV) for 4 weeks. The evaluation was peformed twice(admission day and after treatment for 4 weeks), and we compared the results. Results : 1. VAS, PRS and ${\Delta}t$(by DITI) were decreased after BV for 4 weeks significantly(p<0.01). 2. There was significant correlation between VAS and PRS(p<0.05). 3. There was significant correlation between PRS and ${\Delta}t$(p<0.05). 4. There was no significant correlation between VAS and ${\Delta}t$. Conclusions : BV improved HNP subjectively and objectively, and correlation was found between VAS and PRS and between PRS and ${\Delta}t$. Further study is needed for investigating their correlation.

Objectives: Dry socket may occur secondary to the removal of any tooth. However, most dry socket cases develop in the third molar region. Dry socket is multifactorial in nature and has been treated using various modalities with varying success rates. This study assessed the efficacy of platelet rich fibrin (PRF) in established dry socket. Materials and Methods: Ten patients of either sex aged from 41 to 64 years with established dry socket according to established criteria were treated using PRF. Evaluation was performed by observing the reduction of pain using visual analogue scale, analgesic tablet use over the follow-up period, and healing parameters. Results: Pain was reduced on the first day in all patients with decreased analgesic use. Pain was drastically reduced during follow-up on the first, second, third, and seventh days with a fall in pain score of 0 to 1 after the first day alone. The pain scores of all patients decreased to 1 by the first day except in one patient, and the scores decreased to 0 in all patients after 48 hours. Total analgesic intake ranged from 2 to 6 tablets (aceclofenac 100 mg per tablet) over the follow-up period of 7 days. Healing was satisfactory in all patients by the end of the seventh day. Conclusion: PRF showed early pain reduction in established dry socket with minimal analgesic intake. No patients had allergic reactions to PRF as it is derived from the patient's own blood. PRF showed good wound healing. Our study suggests that PRF should be considered as a treatment modality for established dry socket.

Objectives The purpose of this study is to understand the research trend of reports on forest therapy so far and analyze the Korean medicine therapy being applied in forest therapy programs. Methods We ran a keyword search on domestic databases with the following keyword 'forest therapy, forest healing, forest treatment, recreational forest, forest bath, forest experience'. The search took place in December 2014 and there was no limit to search time. A total of 334 forest therapy articles have been selected. Results The number of research on forest therapy continued to rise from 1985, with 334 articles being published from 84 journals. When those 188 articles were sorted by their contents and methods, except 146 articles of survey on simple satisfaction, recognition and visting, 94 were clinical studies, 79 were literature studies, 15 were experimental studies. Of the 94 clinical researches, there were 52 CCTs (Controled Clinical Trials), 39 ODs (efficacy studies with either a controlled or an Other than controlled Design) and 3 RCTs (Randomized Clinical Trials). Among the clinical researches, there were a total of 21 studies that used Korean Medicine programs, and meditation was the most popular, being used in 18 studies. Herbal food and tea therapy and Qigong were used in 3 studies each, and Korean medicine music programs were used in 2 studies. Conclusions A systematic and standardized Korean medicine forest therapy program must be developed, and based on the program, more research treating diseases should be conducted.

Purpose: This study was conducted to assess the efficacy of prophylactic gingival grafting in the mandibular anterior labial area for preventing orthodontically induced gingival recession. Methods: Eight mongrel dogs received gingival graft surgery at the first (I1) and third (I3) mandibular incisors on both sides based on the following group allocation: AT group (autogenous connective tissue graft on I1), AT-control group (contralateral side in the AT group), CM group (xenogeneic cross-linked collagen matrix graft on I3) and CM-control group (contralateral side in the CM group). At 4 weeks after surgery, 6 incisors were splinted and proclined for 4 weeks, followed by 16 weeks of retention. At 24 weeks after surgery, casts were made and compared with those made before surgery, and radiographic and histomorphometric analyses were performed. Results: Despite the proclination of the incisal tip (by approximately 3 mm), labial gingival recession did not occur. The labial gingiva was thicker in the AT group (1.85±0.50 mm vs. 1.76±0.45 mm, P>0.05) and CM group (1.90±0.33 mm vs. 1.79±0.20 mm, P>0.05) than in their respective control groups. Conclusions: The level of the labial gingival margin did not change following labial proclination of incisors in dogs. Both the AT and CM groups showed enhanced gingival thickness.

Background: This study investigated the effects of zoledronic acid (ZA) on radiation-induced bone loss in C3H/HeN mice. Materials and Methods: C3H/HeN mice were divided into sham control and three irradiated groups (3 Gy, gamma ray). The irradiated mice were treated for 12 weeks with vehicle, amifostine (intraperitoneal injection), or ZA (subcutaneous injection). Grip strength, uterus weight, and serum alkaline phosphatase (ALP), and tartrate-resistant acid phosphatase (TRAP) levels were measured. Tibiae were analyzed using micro-computed tomography. Results and Discussion: Treatment of ZA ($100{\mu}g{\cdot}kg^{-1}{\cdot}week^{-1}$) significantly preserved trabecular bone volume, trabecular thickness, trabecular number, trabecular separation, bone mineral density of proximal tibia metaphysic, and cortical bone volume, but did not alter the uterus weight of the mice. The administration of ZA for 12 weeks lowered serum ALP and TRAP levels in irradiated mice, suggesting that ZA can reduce the bone turnover rate in mice. No differences were apparent between the amifostine-treated group and the irradiation control group. Conclusion: The results indicate that ZA can prevent radiation-induced bone loss in mice.

Ultrasound images are noninvasive, can be observed in real time, have no radiation exposure, do not cause pain, and are not restricted in use depending on the patient's prosthetic implant or medical condition. Since the use of ultrasound in the dental field was first applied for tooth preparation in 1957, the use of diagnostic ultrasound for the first time in 1963 has been reported. Currently, it is used in the diagnosis of soft tissue lesions such as malignant tumor or salivary gland disease, fine needle aspiration test, temporomandibular joint disease, lymph node metastasis, measurement of muscle thickness and inflammatory diseases, differentiation of periapical cyst and granulation tissue, measurement of periodontal tissue thickness. The ultrasound image can be visualized in real time. The clinician can explain the structure to the patient while consulting the patient and consult the patient. When injecting the drug into a specific site or aspirating a specific site or substance, So that it can be confirmed and practiced. Recently, ultrasonic equipment specialized in the dental field has been developed and marketed, and it is expected that the use of ultrasonic waves will become active in the dentistry. In the future, development of popular equipment with size and frequency suitable for dental diagnosis and various researches on maxillofacial ultrasonic anatomy. If clinical studies are continuously carried out to demonstrate efficacy, ultrasound is expected to aid in accurate diagnosis and treatment throughout the dentistry.

Quantitative sputum cytometry facilitates in assessing the nature of bronchitis associated with exacerbations of chronic obstructive pulmonary disease (COPD). This is not assessed in most clinical trials that evaluate the effectiveness of strategies to prevent or to treat exacerbations. While up to a quarter of exacerbations may be associated with raised eosinophil numbers, the vast majority of exacerbations are associated with neutrophilic bronchitis that may indicate airway infections. While eosinophilia may be a predictor of response to corticosteroids (oral and inhaled), the limited efficacy of anti-interleukin 5 therapies would suggest that eosinophils may not directly contribute to those exacerbations. However, they may contribute to airspace enlargement in patients with COPD through various mechanisms involving the interleukin 13 and matrix metalloprotease pathways. The absence of eosinophils may facilitate in limiting the unnecessary use of corticosteroids. The presence of neutrophiia could prompt an investigation for the specific pathogens in the airway. Additionally, sputum measurements may also provide insight into the mechanisms of susceptibility to airway infections. Iron within sputum macrophages, identified by hemosiderin staining (and by more direct quantification) may impair macrophage functions while the low levels of immunoglobulins in sputum may also contribute to airway infections. The assessment of sputum at the time of exacerbations thus would facilitate in customizing treatment and treat current exacerbations and reduce future risk of exacerbations.

This study was performed to process Tofu as an hypolipidemic food using black ginseng. Before processing we performed the ameliorating effect of black ginseng on the serum levels of triglyceride and total cholesterol in diabetic mice (db/db mice). As a result, the diabetic mice, whose diet was supplemented with black ginseng has a reduced level of serum lipid total cholesterol ($124.58{\pm}10.59mg/dL$) compared to non-supplemented diabetic mice, The supplemented mice exhibited a significant decrease (p<0.05) in serum lipid triglycerides ($80.32{\pm}35.40mg/dL$), which provided the efficacy of black ginseng in reducing hyperlipemia, thus indirectly proving the prevention and treatment of obesity. Then we processed Tofu as a hypolipidemic food using 0~8% black ginseng extract. We evaluated the quality characteristic after producing black ginseng Tofu. For color value, as the addition level of color increases, the value of L (lightness) decreased and a (redness), b (yellowness) increased. With increase in black ginseng concentrate additional level increases, the hardness, gumminess, and chewiness values increased (p<0.05), but the springiness and cohesiveness showed no significant differences. In case of sensory evaluation, Tofu with the addition of 2% black ginseng concentrate (BGT2) showed the highest preference overall. To sum up, black ginseng demonstrated pharmacological effects in treating diabetic complications like hyperlipidemia and reducing body deposit fat.

B7-H4 is a member of B7 family of co-inhibitory molecules and B7-H4 protein is found to be overexpressed in many human cancers and which is usually associated with poor survival. In this study, we developed a therapeutic vaccine made from a fusion protein composed of a tetanus toxoid (TT) T-helper cell epitope and human B7-H4IgV domain (TT-rhB7-H4IgV). We investigated the anti-tumor effect of the TT-rhB7-H4IgV vaccine in BALB/c mice and SP2/0 myeloma growth was significantly suppressed in mice. The TT-rhB7-H4IgV vaccine induced high-titer specific antibodies in mice. Further, the antibodies induced by TT-rhB7-H4IgV vaccine were capable of depleting SP2/0 cells through complement-dependent cytotoxicity (CDC) in vitro. On the other hand, the poor cellular immune response was irrelevant to the therapeutic efficacy. These results indicate that the recombinant TT-rhB7-H4IgV vaccine might be a useful candidate of immunotherapy for the treatment of some tumors associated with abnormal expression of B7-H4.

This study evaluated the anti-cholinesterases (ChEs) and antioxidant activities of white ginseng (WG) and black ginseng (BG) roots of Panax ginseng (PG), P. quinquefolium (PQ), and P. notoginseng (PN). Ginsenosides $Rg_1$, Re, Rf, $Rb_1$, Rc, $Rb_2$, and Rd were found in white PG, whereas Rf was not found in white PQ and Rf, Rc, and $Rb_2$ were not detected in white PN. The major ginsenoside content in steamed BG including $RK_3$, $Rh_4$, and 20(S)/(R)-$Rg_3$ was equivalent to approximately 70% of the total ginsenoside content. The WG and BG inhibited acetylcholinesteras (AChE) and butyrylcholinesterase (BChE) in a dose dependent manner. The efficacy of BG roots of PG, PQ, and PN on AChE and BChE inhibition was greater than that of the respective WG roots. The total phenolic contents and 2, 2-diphenyl-1-picryl-hydrazyl (DPPH) scavenging activity were increased by heat treatment. Among the three WG and BG, white PG and steamed black PQ have significantly higher contents of phenolic compounds. The best results for the DPPH scavenging activity were obtained with the WG and BG from PG. These results demonstrate that the steamed BG roots of the three studied ginseng species have both high ChEs inhibition capacity and antioxidant activity.
