Phytophthora capsici is one of major limiting factors in production of pepper and other important crops worldwide by causing foliage blight and rot on fruit and root. Increased demand for the replacement of fungicides has led to searching a promising strategy to control the fungal diseases. To meet eco-friendly agriculture practice, we isolated microorganisms and assessed their beneficial effects on plant health and disease control efficacy. A total of 360 bacterial strains were isolated from rhizosphere soil of healthy pepper plants, and categorized to 5 representative isolates based on colony morphology. Among the 5 bacterial strains (GJ-1, GJ-4, GJ-5, GJ-11, GJ-12), three bacterial strains (GJ-1, GJ-11, GJ-12) presented antifungal activity against P. capsici in an fungal inhibition assay. In phosphate solubilization and siderophore production, the strain GJ-1 was more effective than others. The strain GJ-1 was identified as Bacillus sp. using 16S rDNA analysis. Bacillus sp. GJ-1 was also found to be effective in inhibiting other plant pathogenic fungi, including Rhizoctonia solani, Pythium ultimum and Fusarium solani. Therefore, the Bacillus sp. GJ-1 can serve as a biological control agent against fungal plant pathogens.

The purpse of this study was to evaluate the tissue reaction to hydroxyapatite(HA) in rats given streptozotocin(50mg/kg) to incuce diabetics. A pocket was created on the parietal bone of cranium. 40 rats were divided: 20 induced diabetics (ID) with HA, 20 non-induced diabetics with HA used as control group. Rats from each group were sacrificed at 1, 2, 4, 8, 24 weeks post-implantation. The results of this study were a follows: 1. Inflammatory reaction of ID was more intense than ND at 1 and 2 weeks. 2. Fibrosis in control group was greater than ID, but no significant difference between 2 and 4 weeks after implantation. 3. Dystrophic calcification was no significant difference between ID and control group. 4. No osteogenesis was obseved in both groups. In conclusion, it is important to control the infection at 1 to 2 weeks after the HA implantation and if the infection is controlled, HA in our study was acceptable in both ID rats and ND controls, as inert material, because no osteogenesis was observed in any specimen.

Introduction. In patients with mandibular prognathism, Bilateral Sagittal Split Ramus Osteotomy(BSSRO) combined with orthodontic treatment reduces oral volume and influences tongue and other surrounding tissues. Purpose of this study was to analyze post-operative tongue position and airway dimension, as well as mandibular changes in vertical, horizontal, and angular dimensions. Materials and methods. Height of dorsum of tongue, width of airway, gonial angle and lower facial height of mandibular prognathic patients who visited Kangdong Sacred Heart Hospital from Jan. 2001 to Dec. 2006 were anaylzed via pre-operative and post-operative cephalograms. T-test was used to compare pre-operative and post-operative measurements. Also, correlations among pre-operative measurements of the patients were analyzed. Results and conclusion. A significant correlation was shown between ANS-Xi-PM area and location of dorsum of tongue in pre-operative patients. A significant superior movement of tongue and decrease of airway width was observed in post-operative patients. Also the upper gonial angle decreased significantly.
