An about 5-month-old, female rabbit was presented with pruritus, alopecia and mucopurulent ocular discharge. On physical examination mild to moderate scales on whole body were observed. Dermatological lesions such as alopecia, erythema, papules, pustules and crusts were observed in the eyelids, nose, inner pinna, medial sites of four feet, metacarpal and metatarsal areas, and cranial site of left stifle joint. Also, mild conjunctivitis, blepharitis and keratitis were found. For extensive dermatologic diagnostic evaluation skin scraping, tape stripping, impression smear, combing, wood' light, bacterial culture and fungal culture were performed. Finally, Cheyletiella spp. was found by combing. Many heterophils and eosinophills were appeared in impression smear. The result of fungal culture was negative. Pasteurella spp was cultured. Definitive diagnosis of Cheyletiellosis and secondary Pasteurella spp infection were established. The rabbit was treated with 6 mg/kg of selamectin topically every two weeks and restricted in cage for one month. During one month of initial treatment, clinical signs such as pruritus, alopecia, scales, papules, pustules and crusts were remarkably improved. However, in spite of good therapeutic response of selamectin the rabbit was dead suddenly at 22 days after second administration of selamectin. This case showed that selamectin was possibly effective for cheyletiellosis in rabbit; safety of selamectin for rabbit was not identified.

Objectives : In this study we investigated BDI(Beck Depression Inventory) improvement of poststroke depression Patients who took the acupuncture with aromatherapy, in order to examine its capacity as a new treatment and to establish a primary data for further studies of developments of diverse Practical acupunctures. Methods : Physicians applied the acupuncture with aromatherapy every day for two weeks. We had evaluated baseline characteristics and BDI of all Patients, and revaluated BDI and examined the side effects two weeks later. The qualified Patients were classified into two groups, depression group (more than 10 points and 10 in BDI) and non-depression group (less than 10 points in BDI) according to the baseline BDI. Results : The study was completed with 27stroke patients. The acupuncture with aroma therapy was applied in 18 post-stroke depression patients and 9 non-depression patients for 2 weeks. And the result showed that the BDI scores in the depression group decreased to $16.5{\pm}11.1$ after the treatment (compared to $24.4{\pm}11.5$ before the treatment). so proved the significant effect on post-stroke depression of the acupuncture. On the other hand. the scores in the non-depression group increased to $9.2{\pm}9.5$ (compared to $3.3{\pm}3.0$). Conclusions : The acupuncture with aromatherapy applied on post-stroke depression patients showed the effect of BDI improvement. Further researches are needed to evaluate the distinct functional mechanism of acupuncture with aromatherapy, and to estimate its effectiveness by well-designed randomized controlled trial.

Background Polydeoxyribonucleotide (PDRN) is known to have anti-inflammatory and angiogenic effects and to accelerate wound healing. The aim of this study was to investigate whether PDRN could improve peripheral tissue oxygenation and angiogenesis in diabetic foot ulcers. Methods This was a prospective randomized controlled clinical trial. Twenty patients with a non-healing diabetic foot ulcer were randomly distributed into a control group (n=10) and a PDRN group (n=10). Initial surgical debridement and secondary surgical procedures such as a split-thickness skin graft, primary closure, or local flap were performed. Between the initial surgical debridement and secondary surgical procedures, 0.9% normal saline (3 mL) or PDRN was injected for 2 weeks by the intramuscular (1 ampule, 3 mL, 5.625 mg, 5 days per week) and perilesional routes (1 ampule, 3 mL, 5.625 mg, 2 days per week). Transcutaneous oxygen tension ($TcPO_2$) was evaluated using the Periflux System 5000 with $TcPO_2/CO_2$ unit 5040 before the injections and on days 1, 3, 7, 14, and 28 after the start of the injections. A pathologic review (hematoxylin and eosin stain) of the debrided specimens was conducted by a pathologist, and vessel density (average number of vessels per visual field) was calculated. Results Compared with the control group, the PDRN-treated group showed improvements in peripheral tissue oxygenation on day 7 (P<0.01), day 14 (P<0.001), and day 28 (P<0.001). The pathologic review of the specimens from the PDRN group showed increased angiogenesis and improved inflammation compared with the control group. No statistically significant difference was found between the control group and the PDRN group in terms of vessel density (P=0.094). Complete healing was achieved in every patient. Conclusions In this study, PDRN improved peripheral tissue oxygenation. Moreover, PDRN is thought to be effective in improving inflammation and angiogenesis in diabetic foot ulcers.

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.

Objectives: The purpose of this study was to investigate the behavioral modification of obese adults who underwent nutritional and physical activity education. Twenty obese females, aged 20-60 years old, with BMIs (Body Mass Index) >30 or body fat (%) >40 were subjected to this study. Methods: The physical activity education program consisted of doing exercise in a gymnasium together or home exercise. Dietary attitudes and dietary intakes were assessed using weight control, physical activity, and eating habits. The nutrition-exercise educational period was 12 weeks. Results: After the study period, there was significant improvement in physical activity and eating habits score. Furthermore, there was a significant increase in the dietary intakes of fiber, iron, potassium, vitamin A, vitamin $B_6$, and niacin. Blood pressure, blood glucose, and total cholesterol levels showed a tendency to decrease, but there was no significant difference. BMI, fat mass, abdominal circumference, and visceral fat levels were significantly reduced while muscle mass significantly increased. Conclusions: This study suggests that behavioral modification by nutrition and physical activity education with feedback has positive effects on dietary intake and anthropometric biomarkers in obese adults. Therefore, lifestyle interventions of this kind could be recommended as a method for obesity management.

Background: Supporting the elderly population is presented as a social issue, and it affects age discrimination, which forms a negative perception and avoids the elderly. Since age discrimination lowers the quality of life of the elderly and hinders social unity, it may be important to research related factors. This study examined the physical function as a factor that influences discrimination experiences and aimed to identify the relationship between physical function factors and discrimination experiences. Methods: In this study, we analyzed 20,225 elderly from the 2014 and 2017 survey of living conditions and welfare needs of Korean older persons, conducted nationwide among older than 65 years. Physical function factors are activities of daily living, instrumental activities of daily living, sight discomfort, hearing discomfort, chewing discomfort, and leg strength as factors of interest. We performed multivariable logistic regression that reflected survey characteristics, adjusting for socio-demographic factors, health related factors, and social-support factors. Results: The number of elderly who faced discrimination experiences was 1,175 (5.8%). The results showed that the odds ratio of facing a discrimination experience in the dependent group was significantly higher compared to the independent group when being transferring out of the room (4.05; 95% confidence interval [CI], 1.50-10.88) and difficulty in hearing (1.25; 95% CI, 1.05-1.49). Even with respect to chewing ability, which was significant in models 1 and 2, they face more discrimination experiences (1.30; 95% CI, 1.11-1.53). Conclusion: These research results indicate that an important strategy for preventing age discrimination is to understand the physical function conditions of the elderly and promote the physical functions of the elderly related to transferring, hearing, and chewing; it is necessary to develop a practical intervention plan that considers these aspects.

Background: As South Korea is becoming an aged society very rapidly, the increase in osteoarthritis prevalence raises various public health issues in this country. This study aimed to explore the socio-demographic factors associated with osteoarthritis in the current Korean elderlies. Methods: Using the National Survey of Korean Elderly data (2014, 2017), we analyzed 20,326 elderlies (males, 8,248; females, 12,078) and conducted multivariate logistic regression analyses by sex. The dependent variable is whether a participant was diagnosed with osteoarthritis or not. Independent variables of interest is socio-demographic factors such as age, marital status, household type, residential area, household income, religion, the longest job, the number of close relatives, the number of close friends, and survey year. Control variables are various health behavioral factors and disease-related factors. Results: Prevalence of osteoarthritis was 19.2% in male elderlies and 47.0% in female elderlies. According to the results of the multivariate logistic regression adjusted for all studied control variables, the odds ratio (OR) for having osteoarthritis of under-elementary school graduates (their counterpart was college graduate group) was 1.81 (95% confidence interval [CI], 1.29-2.52) in males and 1.67 (95% CI, 1.12-2.47) in females. The OR of those having a job in agriculture & forestry fishery as their longest job (their counterpart was those who had never participated in labor force during their lifetime) was 5.07 (95% CI, 1.46-17.58) in males and 1.49 (95% CI, 1.27-1.74) in females. In males, the second-low quartile group in household yearly income (their counterpart was the highest quartile group) had the OR of 1.22 (95% CI, 0.98-1.53). In females, the OR of those having a religion of Buddhism (their counterpart was those having no religion) was 1.20 (95% CI, 1.07-1.35) and the OR of those who had no relatives (their counterpart was those having more than 3 close relatives) was 1.31 (95% CI, 1.10-1.56). Conclusion: This study found that in Korean elderlies, education, the longest job, household income, religion, and the number of close relatives are associated with their suffering from osteoarthritis. Further study and designing appropriate interventions are needed to alleviate current and future individual and socioeconomic burdens of osteoarthritis in an aged society like South Korea.

Fibroblast growth factor 21 (FGF21) is an atypical member of the FGF protein family which is highly synthesized in the liver, pancreas, and adipose tissue. Depending on the expression tissue, FGF21 uses endo- or paracrine features to regulate several metabolic pathways including glucose metabolism and energy homeostasis. Different physiologically stressful conditions such as starvation, a ketogenic diet, extreme cold, and mitochondrial dysfunction are known to induce FGF21 synthesis in various tissues to exert either adaptive or defensive mechanisms. More specifically, peroxisome proliferator-activated receptor gamma and peroxisome proliferator-activated receptor alpha control FGF21 expression in adipose tissue and liver, respectively. In addition, the pharmacologic administration of FGF21 has been reported to decrease the body weight and improve the insulin sensitivity and lipoprotein profiles of obese mice and type 2 diabetes patients meaning that FGF21 has attracted huge interest as a therapeutic agent for type 2 diabetes, obesity, and non-alcoholic fatty liver disease. However, understanding FGF21 remains complicated due to the paradoxical condition of its tissue-dependent expression. For example, nutrient deprivation largely increases hepatic FGF21 levels whereas adipose tissue-derived FGF21 is increased under feeding condition. This review discusses the issues of interest that have arisen from existing publications, including the tissue-specific function of FGF21 and its action mechanism. We also summarize the current stage of a clinical trial using several FGF21 analogs.

Objectives: Although the side effects of radiation therapy vary from mucositis to osteomyelitis depending on the dose of radiation therapy, to date, an experimental animal model has not yet been proposed. The aim of this study was to develop an animal model for assessing complications of irradiated bone, especially to quantify the dose of radiation needed to develop a rat model. Materials and Methods: Sixteen Sprague-Dawley rats aged seven weeks with a mean weight of 267.59 g were used. Atraumatic extraction of a right mandibular first molar was performed. At one week after the extraction, the rats were randomized into four groups and received a single dose of external radiation administered to the right lower jaw at a level of 14, 16, 18, or 20 Gy, respectively. Clinical alopecia with body weight changes were compared and bony volumetric analysis with micro-computed tomography (CT), histologic analysis with H&E were performed. Results: The progression of the skin alopecia was different depending on the irradiation dose. Micro-CT parameters including bone volume, bone volume/tissue volume, bone mineral density, and trabecular spaces, showed no significant differences. The progression of osteoradionecrosis (ORN) along with that of inflammation, fibrosis, and bone resorption, was found with increased osteoclast or fibrosis in the radiated group. As the radiation dose increases, osteoclast numbers begin to decrease and osteoclast tends to increase. Osteoclasts respond more sensitively to the radiation dose, and osteoblasts are degraded at doses above 18 Gy. Conclusion: A standardized animal model clinically comparable to ORN of the jaw is a valuable tool that can be used to examine the pathophysiology of the disease and trial any potential treatment modalities. We present a methodology for the use of an experimental rat model that incorporates a guideline regarding radiation dose.
