This study was done to examine patients' wound care knowledge and concerns prior to discharge from a tertiary hospital. The participants in this descriptive survey were 112 patients having wounds. During interview, a structured self-administered questionnaire was filled out. The participants were 71 males and 41 females. Wound types were surgical incision (52.7%), percutaneous wound (26.8%), pressure ulcer (9.8%) and diabetic foot and arterial ulcers (5.4%). Their wound care knowledge was 52.0% of correct answer and the mean of concerns (range 1-7) was 2.79. There was no significant correlation between their knowledge and concerns of wound care. The factors influence on wound care concerns were fear of wound care, wound pain, length of hospital stays, and perceived health condition. This findings showed that discharge patients with a wound had some incorrect knowledge and various concerns about wound care. They may help to direct patient teaching in discharge plan.

During a study to document more fully the parasitic ciliates of Korean freshwater fishes, we found numerous small ciliates in the gills and skin of crucian carp, Carassius carassius. Cursory examination indicated that the ciliate were very similar with Chilodonella sp. In this study, we described the morphometrics of this ciliate in detail and compared with other species of Chilodonella in the world. Numerous small ciliates were observed in the body surface, fins and gills of infected fish and excessive mucus production were seen in those fish. Sometimes ulcer was observed in the body of moribund fish. From the scrutinized observation of the parasite, it was identified as Chilodonella hexasticha. The parasite was dorsoventrally flattened body, without a notch in the posterior margin, and it measured 30-$45{\mu}m$ long and 15-$30{\mu}m$ wide. In number of kineties, the right band ciliature was 3-5 and the left band ciliature was 3-5. The right ventral ciliary band shaped arch and was longer than the left, straight band. It had a single oval macronucleus, 8-$15{\mu}m$ in diameter, a single micronucleus, 2-$4{\mu}m$ in diameter. The cytopharynx was reinforced by 10-16 conspicuous nematodesmata, which shaped like a tube and curved at its inner end. Two contractile vacuoles, one anteriorly at right and the second posteriorly at left were observed in wet mounts. This parasite reproduced by a simple division at $22{\pm}1^{\circ}C$.

The purpose of this study is to investigate the relationship between personality type and symptoms of oral mucosa disease. 393 college students completed the MBTI(Myers-Briggs Type Indicator) and a questionnaire and collected data were analyzed by SAS 9.2 program. The obtained results were as follows : 1. Dysgeusia(p<0.05) and xerostomia(p<0.01) occurred significantly more frequently in I type than E type. 2. Herpetic stomatitis, recurrent aphthous ulcer, glossitis, dysgeusia, burning mouth syndrome and xerostomia seemed to occur more frequently in S type than in N type. 3. Most symptoms of oral mucosa disease seemed to occur the most frequently in the type including NF among 16 types of personality of MBTI. 4. Most subjects had negative attitude in curing their symptoms of oral mucosa disease(p<.0001). Significantly more subjects with I type than E type had negative attitude in curing herpetic stomatitis(p<0.01) and dysgeusia(p<0.05). 5. Most symptoms of oral mucosa disease appeared to occur the most frequently in nervous or sensitive subjects. Therefore a guideline for the individual cure of oral mucosa diseases meeting personality type is necessary.

A 12-year-old, 8.0 kg, spayed female, mixed-breed dog was presented to the Veterinary Medical Teaching Hospital of Chungnam National University (VMTH, CNU). That case has been growing up mass in her left upper hindlimb about for 2 years and has showed vomiting and anorexia for 3 days. The patient was diagnosed with mast cell tumor on the basis of fine-needle aspiration (FNA) cytology techniques. According to World Health Organization clinical staging system for diagnosing mast cell tumors, it was classified into stage IIIa. The patient was treated by adjuvant corticosteroid therapy, but complete surgical excision was not achieved by owner's request. In the early stage of therapy, the size of the mass was gradually reduced with only adjuvant glucocorticoid therapy, so the patient's general condition was maintained well. But after 53 days later, the treatmant was not effective anymore and mass size was increased. Two months later, she was euthanized because of intermittent vomiting and severe respiratory distress. Splenic mass, duodenal ulceration, liver mass and infiltrated mast cell tumor in upper hindlimb muscle region were found in necropsy examination.

A 16-year-old, spayed female, Maltese dog weighing 4.3 kg was presented with a 2-week history of yellowish nose-and oral-discharge, anorexia and lethargy. In physical examination, indefinite ulcerative mass about $3{\times}3$ cm in size in the left sublingual region, severe gingivoperiodontitis, halitosis, moderate dental calculus, fever and swelling of mandible soft tissue were noted. In radiographic view, periodontitis and bone lysis findings on the left rostral part of maxilla and mandible were observed. In complete blood count and blood chemistry test, thrombocytosis, increased levels of serum $NH_3$, AST and ALP were obtained. Urinalysis revealed hematuria and proteinuria. In histological examination, squamous cell carcinoma was diagnosed. No surgery was performed, but combined treatment with carboplatin and piroxicam was initiated. Five days after initiation of medication, because of insistent vomiting, piroxicam was substituted to meloxicam. Although the therapeutic efficacy of meloxicam could not be known; administration of meloxicam might be less potential to gastrointestinal side-effects than piroxicam. The dog totally received 3 times of carboplatin infusion. Five days after third infusion of carboplatin, the dog was hospitalized with severe lethargy, vomiting and bloody diarrhea. In examination, severe renal failure signs were noted, and the dog was euthanized.

Inflammatory polyps in feline ear are nonneoplastic, inflammatory growths that arise from the middle ear or the eustachian tube and extended into the pharynx or external ear canal. Two 2-year-old female Russian blue cats showed 2-3 weeks history of aural discharge, crust formation in external ear, and head or ear shaking. Two masses were surgically excised from ear canal, and submitted for diagnosis. Histopathologically, these masses were covered with hyperplastic ciliated epithelium or nonkeratinizing squamous epithelium with partial erosion and ulceration. The core of masses was consisted of proliferated connective tissue and massive infiltration of mononuclear cells. Immunohistochemically, about 90% of infiltrated mononuclear cells demonstrated CD3 positive T cell. According to both polymerase chain reaction (PCR) and reverse transcriptase-PCR, tissues samples were negative for feline viral pathogens. Based on the clinical, gross, histopathologic findings, these two cases were diagnosed as inflammatory polyps originated from the middle ear in cats.

An 8-year-old male dog weighing 7.9 kg was referred to us for evaluation of exophthalmos and corneal edema of the left eye, on which cataract surgery had been performed 3 years prior. On ophthalmic examination, the left eye showed an extremely high intraocular pressure (47 mmHg), with no menace response, dazzle reflex, or pupillary light reflex. The dog was treated with systemic and topical glaucoma medications. After treatment, corneal edema decreased but IOP did not return to within acceptable limits. Seventeen months later, the dog presented with hyphema, episcleral congestion, and corneal edema attributable to accidental trauma. The owner wished to maintain an attractive ocular appearance, and an intraocular silicone prosthesis (ISP) was thus inserted after the evisceration. Three months postoperatively, a corneal ulcer was detected, but this resolved successfully after prescription of appropriate medication. One year after surgery, no complications related to surgery were evident.

Aeromonas hydrophila is the most common water fish pathogen and cause diseases such as hemorrhagic septicemia, dropsy, ulceration and asymptomatic septicemia. A. hydrophila secretes many extracellular products (ECPs) which contribute to effective infection, wide distribution and great adaptability to environmental changes. Crude ECPs of A. hydrophila CK257, a strain used in this study, exhibits a toxic activity to the animals including mouse, rabbit and fish. Toxic symptoms were indicated by tissue damage and skin injuries in animal. When ECPs were subcutaneously injected to animals, skin damages were observed, appearing like necrosis. Preliminary research demonstrated that the active factors are protein component. The crude ECPs were collected after ammonium sulfate precipitation of cell-free culture supernatant. ECPs were fractionated with the use gel filtration chromatography. Five ECP fractions were obtained, of which one fraction was found to be toxic to goldfish. MALDI-TOF analyses provided two interesting proteases called M35 and M28. Both M35 and M28 are known as metalloprotease. Accordingly, proteins in an active fraction exhibited caseinolytic activity. These proteins were difference of caseinolytic activity under different metallic ions. Also active fraction has elastolytic activity. These results suggested that peptidase M28 and M35 may be a candidate factor for tissue necrosis activity about infection with A. hydrophila.

Inflammatory bowel disease, known as Crohn's disease and ulcerative colitis, is an unexplained disease characterized by chronic inflammation that repeats a cycle of relapse, improvement, and complications. The cause of inflammatory bowel disease is not clearly known, but it is predicted that a complex of various factors precipitate its occurrence. In particular, inflammatory mediators, such as cytokine, induce an increase in cell-mediated inflammatory responses. Focal tissue damage then occurs in the intestinal mucosa because of the weakening of the immune-modulating functions of cotton. Immune and inflammatory responses do not decrease appropriately but continue until they lead to chronic inflammation. Current research has focused on the cytokine genes, which have important roles in these inflammatory responses. Cytokine is a glycoprotein that is produced mostly in activated immune cells. It connects the activation, multiplication, and differentiation between immune cells, which causes focal tissue damage and inflammatory response. Moreover, butyrate, which originates in dietary fiber and plays an important role in the structure and function of the intestinal area, shows control functions in the intestinal immune system by decreasing the proinflammatory cytokine and increasing the anti-inflammatory cytokine. Therefore, this research investigated the molecular mechanism of the anti-inflammatory effects of butyrate to comprehend the cytokine controlling abilities of butyrate in the immune cells. Butyrate is expected to have potential in new treatment strategies for inflammatory bowel disease.
