A three-year old intact female German shepherd dog weighing 32kg was presented with the history of regurgitation and vomiting. Physical examination revealed a thin body condition, hoarse voice, hypersalivation, and pelvic limb weakness. In radiograph, meagaesophagus was identified. The neostigmine challenge test was positive. The titer of acetylcholine receptor (AChR) antibody was 1.58 nmol/L (reference range, <0.6nmol). Therefore, the dog was diagnosed to be suffering with chronic generalized form of acquired myasthenia gravis and followed by treatment with pyridostigmine bromide, 1mg/kg, q12 hrs. Treatment improved the pelvic limb weakness, however intermittent regurgitation and vomiting persisted. This resulted in aspiration pneumonia f3r which antibiotics were administered However, the dog was euthanized due to poor management and owner's request.

Epidermolysis bullosa (EB) is an inherited skin disease characterized by blister formation of the skin following just minor trauma or spontaneously. The main classification of EB is based on the localization of the blistering. In epidermolysis bullosa simplex, the blister formation is intraepidermal; in epidermolysis bullosa junctionalis the blister formation in the epidermal-dermal junction; in the dystrophic forms of EB blister formation is intradermal. Oral manifestations of recessive dystrophic EB are characterized by rampant caries, crowding, microstomia, ankyloglossia, vestibular obliteration. Dental therapy may be well provided to patient with recessive dystrophic EB by using general anesthesia especially in case of poor cooperation. A two years old girl with recessive dystrophic EB visited our clinic for rampant caries. She was hospitalized for severe anemia and fever, and we provided dental therapy under general anesthesia. Extraction of incisors and stainless steel crown restoration of primary molars were performed.

In this paper, we described a case of mass mortality of doctor fish from a private fish hatchery farm in Korea with a history of abnormal swimming behavior, diffuse bleeding on the skin and fins and sudden death caused by fish pathogenic bacteria, Citrobacter freundii. Twelve moribund fish fingerling samples were submitted to College of Veterinary Medicine, Seoul National University in October 2008 for diagnostic examination. Diagnostic results showed that the morphological and biochemical properties of the bacteria isolated from the moribund fish were C. freundii. The remaining diseased fish from the hatchery farm were given treatment based on our recommendation and successfully recovered.

Since urachal abnormalities are uncommon and have various clinical manifestations such as umbilical discharge, periumbilical pain, recurrent urinary tract infection and abdominal mass according to its structure, it is not easy to diagnose. We report our experience of a patient with urachal remnant abscess who presented with gross hematuria initially, and improved after the management with intravenous antibiotics and percutaneous drainage of abscess.

Pleural paragonimiasis is uncommon in the pediatric population and therefore can be challenging to diagnose. This is a case of a 6-year-old girl with pleural effusion who had been having intermittent persistent epigastric pain and erythematous rash on the face, hands, and arms for 6 months. Exudative pleural effusion with prominent eosinophils and serum eosinophilia were observed. As patient showed high immunoglobulin M (IgM) titers against Mycoplasma pneumoniae, she was treated with antibiotics; however, the pleural effusion did not improve during hospitalization. Despite showing negative stool ova and cyst results, patient's serum and pleural effusion were positive for Paragonimus westermani-specific IgGs on enzyme-linked immunosorbent assay. Respiratory symptoms, pleural effusion, and skin symptoms improved after praziquantel treatment.

Peri-implantitis is an inflammatory lesion of the periodontium surrounding an endosseous implant, with progressive loss of the supporting peri-implant bone. The main purposes of treatment for peri-implantitis due to biological factors include addressing the inflammation and restoring a healthy but reduced periodontium around the implant, similar to the treatment of periodontitis in natural teeth. The proposed treatment protocol includes surgical treatment, mainly resective surgery, after non-surgical treatment such as oral hygiene instructions, mechanical cleansing of the fixture, and general or topical antiseptic or antibiotic application according to the extent of inflammation. In this article, we present a 6-year follow-up case showing unusual marginal bone regeneration after resective surgery and decontamination of an implant surface for the treatment of peri-implantitis and discuss the possible reasons.

Streptococcus intermedius is a small, non-motile, Gram-positive, non-sporeforming, and aerotolerant anaerobic coccus. It is a part of the normal microflora in the oral cavity and upper respiratory, gastrointestinal and female urogenital tracts. It is an opportunistic pathogen that causes serious infections in patients with immunocompromised states or cardiac diseases as a result of trauma or invasive procedures. We describe a case of septic arthritis of the hip caused by S. intermedius in an immunocompetent healthy 7-year-old boy without a history of periodontal disease or invasive procedures. He had hip joint pain three weeks ago, and the fever began on the day of the visit. He had been healthy and had not undergone any invasive procedures recently. Septic arthritis of the hip was indicated in the magnetic resonance imaging of the hip. S. intermedius was identified in the hip joint fluid aspiration and blood culture. He was successfully treated with surgical intervention and antibiotic therapy with ceftriaxone followed by amoxicillin for five weeks.

Antimicrobial drug-resistance is natural response to antimicrobial stress based on selection, which weakens chemotherapy effect. Introduction of large numbers of chemotherapeutic agents to clinical practice has generated strains of microorganisms that survive and multiply in vivo with high-drug concentrations. Methicillin-resistant Staphylococcus aureus (MRSA), bacteria found in normal daily life, can be easily ingested through milk vegetables, and meats, etc. MRSA emerged in many port of the world, increasing complex clinical problems. Therefore, new agents are needed to treat MRSA. Glycyrrhiza uralensis was extracted using 80% MeOH to investigate its antimicrobial activity against MRSA stains KCCM 11812, 40510, and 40512 through bacterial measurement, disc diffusion, and O.D. methods, MIC values, MRSA gene expression investigation, and scanning electron microscope observation. Results revealed MecA, Mecl, MecRI, and FemA were the most highly manifested MRSA genes. Methanolic extract of G. uralensis significantly inhibited MRSA and thus could be used in development of antibacteria.

The absorption and excretion times of oxolinic acid(OX) used in farms as new aquatic antibiotics commonly were evaluated with determination of the effects of water temperature and feeding to parameters by using the bioassay technique. On the same time, antibacterial activity and the complex formation of oxolinic acid with serum proteins of two different fishes were compared to those oxytetracycline(OTC). With more than 10 times lower MIC values than those of OTC in the strains among 13 analyzed fish pathogens. OX did not show the decresed antibacterial activity by the binding of serum proteins in carp and tilapia. It implies more powerful potential of OX as aquatic medicine OTC. The serum concentration of OX after different administrations the oral, i.m., i.v and dipping methods were compared. The higher beginning concentration in serum and faster excretion times were obserbed in i.m. and dipping methods respectively. In the oral and i.m. administration, peak serum concentration after 24－48 hrs and slow excretion times demonstrated in both methods. These pharmacokinetic characteristics similar at $30^{\circ}C$ and $20^{\circ}C$ water temperature conditions, however, beginning serum concentration of OX in fish dipped in $50mg/\ell$ sol after starvation for 2 wks was appeared lower than those of fed fish. It suggests the importance of biological condition of the gill or skin for absorption of antibiotics after dipping administration.

Plant extract has attracted considerable interest in oral disease therapy. The present study was performed to observe the antibacterial effect on cariogenic Streptococcus mutans GS5 and Streptococcus sobrinus 6715, and periodontopathic Actinobacillus actinomycetemcomitans Y4 of phytoncide from Chamaecyparis obtusa Sieb. et Zucc employing the measurement of optical density, viable cell counts, and antibiotic sensitivity. The results were as follows: 1. Minimum inhibitory concentration of the phytoncide for S. mutans, S. sobrinus, and A. actinomycetemcomitans was observed to be 0.5%, 1%, and 0.2%, respectively. 2. Minimum bactericidal concentration of the phytoncide for S. mutans, S. sobrinus, and A. actinomycetemcomitans was determined to be 0.5%, 2%, and 0.2%, respectively. 3. The bacteria exposed to the phytoncide become more sensitive to antibiotics. The phytoncide enhanced significantly antibacterial activity of ampicillin against S. mutans and S. sobrinus. It also increased significantly the activity of penicillin and amoxicillin against S. sobrinus. In contrast, the phytoncide augmented the activity of amoxicillin and cefotaxime against A. actinomycetemcomitans but the increase was not statistically significant. The overall results indicate that phytoncide from Chamaecyparis obtusa Sieb. et Zucc used for this study has a strong antibacterial activity against cariogenic and periodontopathic bacteria and that it also has permeabilizing effect on certain antibiotics against these bacteria. Therefore, the phytoncide may be used as a candidate for prevention and therapeutic agent against oral infectious disease including dental caries and periodontal disease.
