Antibiotic is one of the mainly prescribed drugs in dental office. The substantial part of all antibiotics used in dental office is given to patients without signs or symptoms of infection to prevent infections, and antibiotics became the most widely abused prescribed drugs on the basis of inappropriate indications, dosages and durations. Considering that antibiotics are one of the drugs that affect not only a single patient but also entire populations of individuals through their collective effects on microbial ecology, the importance of proper use of antimicrobial therapy can hardly be overemphasized. Therefore, the main considerations for antibiotic therapy in denial office were summarized here.

Radiation therapy has been widely applied for cancer treatment. Childhood acute lymphocytic leukemia (ALL), characterized by frequent central nervous system involvement, is a well documented disease for the effect of prophylactic cranio-spinal irradiation. Irradiation, however, acts as an oncogenic factor as a delayed effect and it is rare that glioblastoma multiforme develops during the remission period of ALL. We experienced a pediatric radiation-induced GBM patient which developed during the remission period of ALL, who were primarily treated with chemotherapeutic agents and brain radiation therapy for the prevention of central nervous system (CNS) relapse. Additionally, we reviewed the related literature regarding on the effects of brain irradiation in childhood and on the prognosis of radiation induced GBM.

Kombucha fermentation broth has been used as a popular health beverage and an alternative therapy with prophylactic and therapeutic benefit. We tried to establish optimal culture conditions for Kombucha fermentation in milk and to investigate cytotoxicity and antioxidative enzyme activity of Kombucha broth against normal human fibroblasts. The optimal conditions of Kombuch culture were established to 3$0^{\circ}C$, 20∼23 hours by DPPH radical scavenging test. There were positive effects on cell growth while no cytotoxicity against primary normal human diploid fibroblasts was found. The activites of glutathione peroxide and catalase in the cells treated by hydrogen peroxide (1 mM) alone and by hydrogen peroxide with Kombucha broth (1 mg/mι) were significantly different (p＜0.05). These results suggest that Kombucha broth could be developed as an antioxidant agent for a new cosmetic material.

In experimental lung metastasis of colon26-M3.1 carcinoma cells, we found that the prophylactic or therapeutic admini-stration of Inonotus obliquus extracts significantly inhibited lung metastasis. In an in vitro cytotoxicity analysis, the extracts did not affect colon26-M3.1 cell growth at concentrations up to 1000 ${\mu}g/m{\ell}$. Peritoneal macrophages that were stimulated with the extracts produced $TNF-{\alpha}$. These data suggest that Inonotus obliquus extract has antitumor activity to inhibit tumor metastasis, and its antitumor effects are partially associated with macrophages activation.

Coccidiosis is a major parasitic disease in the poultry industry, with great economic implications worldwide. It is a ubiquitous protozoan infection caused by several species of the genus Eimeria (host-specific) that colonize and reproduce in the intestine of birds, ultimately altering the health and performance of the flock. At present, several methods are used to diagnose coccidiosis in poultry, including field and laboratory techniques (intestinal lesion scoring, oocyst counting in feces, and biochemical and molecular diagnosis). Traditionally, diagnosed flocks have been treated either by vaccination to improve the active immunity of the birds against coccidiosis or supplementation of prophylactic anticoccidials to ameliorate the deleterious effects of coccidiosis. However, these methods has certain drawbacks such as vaccine-induced coccidiosis, drug resistance, and residual drug accumulation in the host. Consequently, alternative safe anti-coccidial agents, including the use of phytogenic compounds, have been explored for preventing coccidiosis. Here, we provide a simple overview of the literature on poultry coccidiosis by focusing on the etiology, diagnostic practices, and preventive measures.

Objectives The purpose of this study is to evaluate the clinical effectiveness and prophylactic treatment effectiveness of Gagam-Bopyeyangyeongjeon(GGBYJ) on the Lung Weakness Children(肺系虛弱兒) who catch cold easily. Methods The study has been carried out from 27 children, who were treated with GGBYJ in Department of Pediatrics, $\bigcirc\bigcirc$ Oriental Medical Hospital from August to December in 2009. The study was completed through patient chart review and telephone survey. Results 1. Immediately after the treatment, there was significantly decreasing(p=0.005) on respiratory symptoms in the Lung Weakness Children(肺系虛弱兒) who catch cold easily. 2. After the treatment, when season changes (three months later), there were preventive and continuous effects on reducing morbidity and on decreasing degree of symptoms against new respiratory infections compared to the previous year before taking medicine. 3. GGBYJ improved the respiratory symptoms, and also anorexia, constipation, heights, skin and fatigue. Conclusions In conclusion, there were significant clinical and preventive effectiveness of GGBYJ for the Lung Weakness Children(肺系虛弱兒) who caught a cold easily. Further studies are needed with more clinical cases.

Viability plays an important role in the beneficial microbes (probiotics) to produce health benefits. However, this idea has been changed after the invention of the term "paraprobiotics," indicating that non-viable microbes could produce health benefits similar to those produced by live probiotics. Occasionally, it might be dangerous to administer live probiotics to people with weak immunity. In such cases, ingestion of paraprobiotics could be a potential alternative. The definition of paraprobiotics refers to the use of inactivated (non-viable) microbial cells or cell fractions to provide health benefits to the consumer. Paraprobiotics have attracted much attention because of their long shelf life, safety, and beneficial effects, such as modulation of immunity, modification of biological responses, reduction of cholesterol, anti-inflammatory, and antiproliferative properties. These features indicate that paraprobiotics may play a vital role in improving the health of the consumer by enhancing particular physiological functions, even though the exact underlying mechanisms have not yet been completely elucidated. In this mini-review, we briefly discuss the historical backgrounds of paraprobiotics and evidence of their health-promoting effects, prophylactic, and therapeutic properties.

Peroxisome proliferator-activated receptor-gamma ($PPAR{\gamma}$) is expressed at very high levels in the gastrointestinal epithelium. Many of the functions of $PPAR{\gamma}$ in gastrointestinal epithelial cells have been elucidated in recent years, and a pattern is emerging which suggests that this receptor plays an important role in gastrointestinal physiology. There is also strong evidence that $PPAR{\gamma}$ is a colon cancer suppressor in pre-clinical rodent models of sporadic colon cancer, and there is considerable interest in exploitation of $PPAR{\gamma}$ agonists as prophylactic or chemopreventive agents in colon cancer. Studies in mice and in human colon cancer cell lines suggest several mechanisms that might account for the tumor suppressive effects of $PPAR{\gamma}$ agonists, although it is not in all cases clear whether these effects are altogether mediated by $PPAR{\gamma}$. Conversely, several reports suggest that $PPAR{\gamma}$ agonists may promote colon cancer under certain circumstances. This possibility warrants considerable attention since several million individuals with type II diabetes are currently taking $PPAR{\gamma}$ agonists. This review will focus on recent data related to four critical questions: what is the physiological function of $PPAR{\gamma}$ in gastrointestinal epithelial cells; how does $PPAR{\gamma}$ suppress colon carcinogenesis; is $PPAR{\gamma}$ a tumor promoter; and what is the future of $PPAR{\gamma}$ in colon cancer prevention?

Leuconostoc mesenteroides H40 (H40) was isolated from kimchi, and its probiotic properties and neuroprotective effect was evaluated in oxidatively stressed SH-SY5Y cells. H40 was stable in artificial gastric conditions and can be attached in HT-29 cells. In addition, H40 did not produce β-glucuronidase and showed resistant to several antibiotics. The conditioned medium (CM) was made using HT-29 cells refined with heat-killed probiotics (Probiotics-CM) and heated yogurts (Y-CM) to investigate the neuroprotective effect. Treatment with H40-CM not only increased cell viability but also significantly improved brain derived neurotropic factor (BDNF) expression and reduced the Bax/Bcl-2 ratio in oxidatively stress-induced SH-SY5Y cells. Besides, probiotic Y-CM significantly increased BDNF mRNA expression and decreased Bax/Bcl-2 ratio. The physicochemical properties of probiotic yogurt with H40 was not significantly different from the control yogurt. The viable cell counts of lactic acid bacteria in control and probiotic yogurt with H40 was 8.66 Log CFU/mL and 8.96 Log CFU/mL, respectively. Therefore, these results indicate that H40 can be used as prophylactic functional dairy food having neuroprotective effects.
