  • Low-fat and sugar-free (LFSF) cookies were developed for patients with metabolic syndrome X, such as obesity, diabetes, coronary heart disease, and hypertention, using artificial sweeteners (mixture of aspartame and saccharin), pectin and herb extracts such as Polygonatum Odoratum (Mill) Druce, Schizandrae Fructus and Lycii Fructus, without sugar and fats. LFSF cookies were composed of 7.5 : 1 of aspartame and saccharin, 5% pectin, 49% protein, and 5% herb extracts, with reduced fat level. The values for area under the curve in oral glucose tolerance tests were significantly lower in 90% pancreatomized-(Px, n = 8) and sham - operated (Sham, n = 8) rats which consumed LFSF cookies, than the control, which consumed regular cookies. Blood glucose levels were higher and the peak levels were significantly lower in the LFSF cookies group than the control group of Px and Sham rats. Blood glucose levels of healthy female college students (n = 10) at 30 and 60 min after the consumption of 30 g LFSF and regular cookies were not different, but they were significantly lower in the LFSF-cookies group in diabetes patients (n = 10). In conclusions, LFSF cookies was considered as a good snack for diabetic patients.

  • Objectives : Aspergillosis of central nervous system(CNS) is a rare pathologic condition and it has been known to be difficult to diagnose and treat. We analyzed seven cases of central nervous system aspergillosis. The clinical characteristics, and the problems in diagnosis and treatment are discussed with review of previous literatures. Material and Methods : We reviewed the clinical records, radiological findings, and pathologic reports of 7 patients with aspergillosis which involved CNS. Results : Five patients were immunocompetent, and infection was related with previous operation in 4 of them. Two patients were immunocompromised and had no history of operation. Five patients had intracranial lesions and two had spinal lesions. Mean duration from the onset of initial symptom to pathologic diagnosis was 2.4 months. Mean duration from the previous operation to the onset of symptom was 9.3 months, and from the onset of symptom to diagnosis was 2.9 months in the patients who had histories of operation. All of them were treated with surgical procedures and intravenous and oral antifungal agents, resulting in cure in 6 cases. Mean duration of the treatment was 4.9 months. Conclusion : Because aspergillosis of CNS is a rare disease and is difficult to be differentiated from the pyogenic abscess or recurrent tumor, the pathologic diagnosis is very important for adequate treatment. Although the prognosis of aspergillosis of CNS has been known to be poor, adequate surgery for both diagnosis and treatment and antifungal chemotherapy resulted in good outcome.

  • In order to explore an effect of interaction of Streptococcus gordonii, Fusobacterium nucleatum and Porphyromonas gingivalis that are bacteria relevant to periodontal disease on its growth, the bacteria were incubated in trypticase soy hemin menadione broth at $37^{\circ}C$ $CO_2$ incubator for 7 days through anaerobic jar by single and co-culture with heat treated dead bacteria under anaerobic gas pack. In order to confirm growth level, absorbance was measured and for confirming colony structure and form, it was observed with scanning electron microscope. In order to confirm an effect on pathogenicity of P. gingivalis, real time reverse transcriptase polymerase chain reaction was implemented for expression analysis for rgpA gene that produces HRgpA which is gingipain. As a result, the following conclusion was obtained. Colony formation of S. gordonii and P. gingivalis was increased by other dead bacteria and in case of F. nucleatum, its colony formation was showed an aspect of being increased by dead bacterium of P. gingivalis but decreased by dead bacterium of S. gordonii. Therefore, it is considered that the strains being used for this study would affect interactively through bacterial cell itself as well as their interaction factor at the time of colony formation.

  • Purpose: The aim of this study was to evaluate the effects of locally delivered 1% alendronate (ALN) gel used as an adjunct to non-invasive periodontal therapy. Methods: Ligature-induced periodontitis was performed in 96 rats. The ligature was tied in the cervical area of the mandibular left first molar. The animals were randomly divided into 4 groups: 1) NT, no treatment; 2) SRP, scaling and root planning; 3) SRP/PLA, SRP followed by filling the periodontal pocket with placebo gel (PLA); and 4) SRP/ALN, SRP followed by filling the periodontal pockets with 1% ALN gel. Histomorphometric (percentage of bone in the furcation region [PBF]) and immunohistochemical (receptor activator of nuclear factor-κB ligand, osteoprotegerin, and tartrate-resistant acid phosphatase) analyses were performed. Data were statistically analyzed, with the threshold of statistical significance set at P≤0.05. Results: The SRP, SRP/PLA, and SRP/ALN groups presented a higher PBF than the NT group (P≤0.01) at 7, 15, and 30 days. The SRP/ALN group presented a higher PBF than the SRP/PLA group in all experimental periods, as well as a higher PBF than the SRP group at 15 and 30 days. No differences were observed in the immunohistochemical analyses (P>0.05 for all). Conclusions: Locally delivered 1% ALN gel used as an adjunct to SRP enhanced bone regeneration in the furcation region in a rat model of experimental periodontitis.

  • Microcephalic osteodysplastic primordial dwarfism type II (MOPD II) is an autosomal recessive inherited disorder form of primordial dwarfism, caused by mutations in the pericentrin gene. The purpose of the study was to examine the clinical and radiological features, physicochemical properties and microstructures of the tooth affected with MOPD II. The mandibular 2nd molar was collected from the MOPD II patient. Micro-computerized tomography, scanning electron microscopy, energy dispersive spectrometry and Vickers microhardness analysis were performed on the MOPD II and the normal control. The morphology of the MOPD II tooth appeared to have malformed pulp and root and showed a small size. The mineral density measurement showed that the MOPD II tooth had similar scores in the enamel, but lower scores in the root 1/2 and apical dentin compared to the normal control. The microhardness values were smaller in the cusp enamel, root 1/2 dentin and apical dentin of the MOPD II compared to the normal control. In this study, the dental characteristics and the physicochemical properties of a tooth affected with MOPD II were analyzed to improve understanding of the oral manifestations of the disease and to assist in proper dental treatment by identifying precautions.

  • White jelly fungus (Tremella fuciformis Berk) is effective for hypertension, diabetes, obesity, lung disease, beauty, and has been known as an elixir of life in ancient Chinese dynasty. In this study, we investigated the anti-obesity and diabetic effects of the fermented white jelly fungus extract by the bioconversion process. We fed an obesity-inducing mouse with 5% non-fermented Tremella fuciformis (TF), 2.5% fermented Tremella fuciformis (FTF), and 5% FTF containing High Fats Diet (HFD) and HFD for 8 weeks, respectively. The oral glucose tolerance test (OGTT) was performed analysis after 7 weeks of feeding and the dietary intake, food efficiency ratio, body weight, liver, epididymal fat weight, and serum insulin level were measured after 8 weeks of feeding. Also, HOMA-IR was analyzed. The concentrations of serum total cholesterol, triglycerides test was analyzed. The FTF compare with 5% TF and HFD confirmed that 5% FTF reduced body weight, tissue weight, triglycerides concentration, HOMA-IR, respectively. As a result, we confirmed that the fermented white jelly fungus has the anti-obesity effect. Finally, this study can be used a basic data for obesity treatment using fermented white jelly fungus.

  • Benign prostatic hyperplasia (BPH) is the most common urogenital disorder in men, benign tumor and is a typical disease deteriorating the quality of old men's lives, and its prevalence increases with age. Though the molecular pathogenesis of BPH has not yet been clearly revealed, it is known that the variation and aging of the endocrine including sex hormone may cause BPH. Especially the hypertrophy of the prostate cell by the formation of the excessive dihydrotestosterone (DHT) is estimated to cause BPH. If testosterone exists excessively in blood, a lot of DHT is produced in prostate by $5{\alpha}-reductase$. Thus, in this study we tried to analyze haematological change and histopathological change by using the model rat with BPH caused by hypodermic injection of testosterone to prove the effect of Houttuynia cordata extracts on BPH. Rats were divided into four experimental groups: no treatment group (N), the testosterone injection and D.W treatment group (DO), the testosterone injection and Houttuynia cordata treatment group (HO) and testosterone injection and finasteride treatment group (FO). Prostate weight, volume and weight ratio in the HO and FO groups were significantly lower than the DO group. Testosterone and DHT levels in the HO group were significantly lower than the DO group. The HO and FO groups showed trophic symptoms and were lined by flattened epithelial cells, thus, the stromal proliferation is relatively low as compared to the DO group. These results suggest that Houttuynia cordata may control benign prostatic hyperplasia.

  • Due to a rapidly expanding aging population, the incidence of degenerative bone disease has increased, and efforts to handle the issue using regenerative medicine have become more important. In order to control various bone diseases such as osteoarthritis and osteoporosis, regenerative medicine utilizing adult stem cells has been extensively studied. And it is now clear that the mitochondrial energy metabolism, oxidative phosphorylation, is important for the process of stem cell differentiation. Interestingly, a recent study reported that salicylate promotes mitochondrial biogenesis by regulating the expression of $PGC-1{\alpha}$ in murine cells. However, the possible effects of salicylate on osteogenic differentiation through increased mitochondrial biogenesis in stem cells remain unknown. Thus, here we investigated whether salicylate could influence osteogenic differentiation and mitochondrial biogenesis of periosteum-derived mesenchymal stem cells (POMSCs). We found that salicylate treatments of POMSCs undergoing osteogenic differentiation increased the activity of alkaline phosphatase, a well-known early marker of bone cell differentiation. In addition, we observed that mitochondrial mass was increased by salicylate treatments in POMSCs. Together, these results indicate that salicylate can enhance osteogenic differentiation and mitochondrial biogenesis in POMSCs. Therefore, the findings in this study suggest that small molecules augmenting mitochondrial function such as salicylate can be a novel modulator for osteogenic differentiation and regenerative medicine.

  • The purpose of this study was to provide information on the treatment and management of diabetic patients using all the available data of the Korea National Health and Nutrition Examination Survey (KNHANES, 2013-2015) on the serological and complication patterns of cardiovascular disease (CVD) according to the duration of diabetes mellitus (DM). KNHANES consists of health questionnaires, screenings, and nutrition surveys. The study subjects were 1,316 persons who were aged between 18 and 80 years and who answered the duration of DM. DM was classified as 0-5, 6-10, 11-15, 16-20, and over 20 years according to duration of DM. The longer the duration of DM, the older the BMI, the lower the smoker, the higher the HbA1c and the lower the glomerular filtration rate. Total cholesterol, LDL-C and triglyceride levels were low and HDL-C levels were similar. The proportion of patients receiving insulin and oral hypoglycemic agents increased. The longer the duration of DM, the worse blood glucose control and the increased risk of microvascular and macrovascular complications. To prevent these complications, intensive care and monitoring should be used to control the risk factors.

  • A three-dimensional (3D) intraoral scanner, which is one of the major developments in digital dentistry, is widely used in fixed prosthodontics. The application of intraoral scanner is now increasing in removable prosthodontics. Sclerotic change induced by scleroderma causes the limitation of mouth opening and multiple loss of the teeth. Conventional prosthodontic procedures are challenging for patients with this disease. This study showed a case of digital approach to the removable prosthodontic treatment of a patient who had the scleroderma and the consequent microstomia. At the provisional stage, the optical impression of patient's oral structures was digitally obtained. Using a 3D printer, the provisional dentures were fabricated. After extraction of hopeless tooth, the definitive digital impression was taken and the metal frameworks were fabricated, based on the data acquired from the impression. The definitive removable partial dentures were completed and delivered to the patient, who was satisfied with the prostheses.
