An 8-year-old spayed female domestic shorthair cat was presented with a chief complaint of chronic nasal discharge and dyspnea. Physical examination revealed pyohemorrhagic nasal discharge, inspiratory dyspnea and stertor, and an enlarged right mandibular lymph node. Abnormalities of blood works and serum chemistry included mildly increased hematocrit, and globulin concentration. Serologic tests for FeLV and FIV, and a panel of polymerase chain reaction tests for Chlamydophila felis, Feline Calicivirus, Herpesvirus, Bordetella, Mycoplasma felis, and H1N1 influenza was all negative. Only radiographic finding showed increasing soft tissue density in the right nasal cavity and computed tomography disclosed soft tissue/fluid opacification in the right nasal cavity, paranasal sinus, and pharyinx along with slight deviation to the right of the osseous nasal septum. Focal lysis of ventral nasal septum was also suspected in CT scan. Cytological evaluation of fine needle aspirate smears of the enlarged mandibular lymph nodes revealed numerous fungal yeasts having variably thick capsule both extracellularly and intracellularly with low numbers of macrophages. Some yeasts showed narrow based budding, which was a consistent finding with Cryptococcus organisms. Serum protein electrophoresis was a polyclonal consistent with chronic infection and serum was submitted for a fungal serology panel test. In serologic tests Cryptococcus antigen titer was 1 : 32,768. In vitro culture was unsuccessful. Treatment was initiated with administration of fluconazole, clindamycin, and tocopherol. Clinical signs resolved within 3 days after the initial treatment. The cat was discharged and scheduled for periodic evaluation and continued therapy, but was lost to follow-up thereafter.

Purpose: The incidence of shigellosis had been decreased due to the use of antibiotics and the improvement of environmental sanitation but recently increases again. Shigellosis occurrs in mass outbreak through unsanitized meal preperation refered from welfare facility and school. We observed epidemic aspect and clinical coarse of childhood shigellosis. Methods: from December 2001 to January 2002, 22 inpatients with shigellosis in Dongbu Municipal Hospital were observed epidemiologically, clinically and microbiologically. Results: 1. The sexual ratio was 1:1 and mean age was $5.5{\pm}1.4$ years (14 months to 11 years). 2. The clinical manifestations were following: diarrhea (95.5%), high feve (10%) and asymptomatic (4.5%). The mean duration was $3.9{\pm}2.1$ days (1 to 12 days). All patients had no complication and normal serologic test. 3. S. sonnei was cultured in rectal swab, and was resistant to TMP/SMX and ampicillin, but susceptible to ampicillin/sulbactam and the 3rd generation cephalosporins. 4. The patients were treated by antibiotics with conservative treatment including electrolytes and fluid therapy for 5 days, resulting in improvement confirmed by negative reaction on stool culture. 5. These cases were all occurred in mass outbreak in day care center and were suspected to be secondary infection by members of family. Conclusion: This shigellosis occurred in day care center was secondary infection due to S. sonnei and had mild clinical coarse and improvement after antibiotic treatment.

Purpose: This study examined the clinical outcomes and usefulness of triamcinolone acetonide (TA) injections as an option in the conservative treatment of patients with lateral malleolar bursitis of the ankle. Materials and Methods: A total of 27 patients (27 ankles), in whom TA injection had been performed between March 2016 and June 2017, were reviewed retrospectively. After the aspiration of fluid in the lateral malleolar bursal sac, 1 mL (40 mg) of TA was injected into the malleolar bursal sac. After the injection, the ankle was compressed with an elastic cohesive bandage for 2 to 4 weeks. The clinical outcomes and side effects were evaluated at the following time points: 2 weeks, 4 weeks, 3 months, 6 months, and 1 year after TA injection therapy. The responses to treatment were assessed according to the degree of fluctuation, shrinkage of the bursal sac, and soft tissue swelling. Results: The mean age was 62.1 years (range, 41~81 years); there were 19 males and 8 females. Complete resolution was observed in 26 patients (96.3%) after the first or second application of a TA injection, and a partial response was observed in 1 patient (3.7%) after the first TA injection. The physical component scores of Medical Outcomes Study 36-item Short-Form Health Survey improved from 71.1 to 76.0 at the last follow-up (p=0.001). Associated complications were 1 patient (3.7%) with skin atrophy and 3 patients (11.1%) with transient hyperglycemia in diabetes mellitus. Conclusion: TA injection is a useful and safe procedure for patients not responding to the usual conservative treatment of lateral malleolar bursitis of the ankle.

Objective : Lithospermum Erythrorhizon (LE) has been used as an anti-bacterial and anti-inflammatory agent. However, it is unclear that LE aqueous extract could show the anti-inflammatory effects in RAW 264.7cells. The purpose of this study was to investigate the anti-inflammatory effect of aqueous extract from LE on lipopolysaccharide (LPS) - induced inflammatory response. Methods : To measure out the cytotoxicity of LE, we performed the MTT assay. To evaluate the anti-inflammatory effects of LE, we examined the inflammatory mediators such as nitric oxide (NO), prostaglandin E2 ($PGE_2$) and pro-inflammatory cytokines (tumor necrosis factor (TNF)-${\alpha}$, interleukin, (IL)-$1{\beta}$ and (IL)-6) on RAW 264.7 cells. We also examined molecular mechanisms such as mitogen-activated protein kinases (MAPKs) and nuclear factor-B (NF-${\kappa}B$) activation by western blot. Results : Aqueous Extract from LE itself did not have any cytotoxic effect in RAW 264.7 cells. Aqueous extract from LE inhibited LPS-induced productions of inflammatory mediators such as NO, $PGE_2$, and pro-inflammatory cytokines including TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 in RAW 264.7cells. In addition, LE inhibited the phosphorylation of p38 kinases (p38), c-Jun $NH_2$-terminal kinase (JNK), and NF-${\kappa}B$ activation in RAW 264.7 cells. Conclusion : LE down-regulated LPS-induced production of inflammatory mediators through the inhibition of p38, JNK and NF-${\kappa}B$ activation. Taken together, these results could provide the evidence for the anti-inflammatory effects of LE. Therefore, LE may be a novel target in the management of inflammation and help to support a potential strategy for prevention and therapy of inflammatory diseases.

Objectives : The purpose of this study is to report the effect of Korean medical treatments on idiopathic bilateral strabismus. Methods : We treated a 43-year-old male idiopathic bilateral strabismus patient who was told to wait without a prescription as there was no problem in intraocular pressure test, fundus test, brain computed tomography, brain magnetic resonance imaging and angiography test, and cerebrospinal fluid test. The patient was admitted to Cheonan Korean medical hospital for 3 months to get Korean medical treatments including acupuncture, electroacupuncture, vapor treatment, pharmacopuncture therapy. The degree of improvement in idiopathic bilateral strabismus was determined by the objective measures of internal and external rotation disorders, and the patient's subjective opinions on eye pain and double vision discomfort. Results : The results of this patient showed distinct improvements on objective measures of internal and external rotation disorders in both eyes. Distance from the outer corner of the right eye when abducted decreased from 7mm to 0mm, and left eye decreased from 7mm to 0mm. Distance from the inner corner of the right eye when adducted decreased from 5mm to 0mm, and left eye decreased from 4mm to 0mm. In addition, eye pain decreased from 10 to 0 and diplopia decreased from 10 to 2 according to the patient's subjective opinions. Conclusions : This study shows the possibility that such medical treatment in Koreans can improve the rare idiopathic bilateral perspective among strabismus patients.

A dog (2-year old, female, Shih-Tzu) presented with hyperthermia and right-sided facial paralysis characterized by the inability to close the right eye and drooling from the right side of the mouth after H3N2 influenza vaccination [A/Canine/Korea/01/07(H3N2) strain; Caniflu-Max, Bionote, Hwaseong, Gyeonggi-do, ROK]. To determine the cause of the fever and neurological symptoms, physical examination, ophthalmic examination, thoracic and abdominal radiography, abdominal ultrasonography, complete blood counts, serum chemistry values, and electrolyte levels were determined. In addition, Cerebrospinal fluid analysis, antinuclear antibody test, fever of unknown origin polymerase chain reaction (PCR) panel, tick-borne pathogen PCR panel were performed. As a result, hyperthermia, leukocytosis, and elevated C-reactive protein were confirmed. In addition, neurological examination revealed decreased right eyelid reflexes, corneal reflexes, threat response, and facial sensation, it was possible to suspect problems with the trigeminal and facial nerves of the cranial nerve. Magnetic resonance imaging revealed a lesion suggestive of myositis in the right muscular lesion at atlanto-occipital junction level on site of vaccine injection. Therefore, right-sided facial paralysis was tentatively determined to be a secondary cause of nerve damage caused by myositis. The patient was treated with immunosuppressants such as prednisolone and mycophenolate mofetil. After 3 months of immunosuppressant therapy, the patient's symptoms improved.

Purpose: We evaluated the usefulness of Re-188 sulfur colloid for radiation synovectomy and therapy of intraperitoneal metastasis. Materials and Methods: We investigated the labeling efficiency of Re-188 sulfur colloid on various conditions. The stability of Re-188 sulfur colloid was observed at room temperature for 24 h and in human serum and synovial fluid for 72 h. The particle size distribution of Re-188 sulfur colloid was measured by filtering with various pore size filters. Animal experiment was performed in mice and rabbits. Results: The labeling efficiency of Re-188 sulfur colloid was $64.5{\pm}5.8%$ (n=5) at the conditions of sodium thiosulfate 40 mg, EDTA $Na_2.2H_2O$ 0.8 mg, $KReO_4$ 0.8 mg at pH 1. After purification, the radiochemical purity was higher than 99%. The stability of Re-188 sulfur colloid was high (>99%) at room temperature for 24 h and in human serum and synovial fluid for 72 h. The particle size distribution of Re-188 sulfur colloid was 0.3% ($<1{\mu}m$), 11.2% ($1{\sim}5{\mu}m$), 25.8% ($5{\sim}10{\mu}m$) and 52.8% ($>10{\mu}m$). In mice, 1 h postinjection of Re-188 sulfur colloid into tail vein, uptakes in lung, liver and muscle were $37.30{\pm}5.36$, $32.33{\pm}1.79$, $6.60{\pm}0.02%$ ID/organ respectively. After i.p. injection in mice, the uptakes of extraperitonial organs of Re-188 sulfur colloid at 1 and 24 h were $0.1{\pm}0.1$, $0.4{\pm}0.1%$ ID/organ, and the excretions through urine and feces (${\sim}70 h$) were low ($2.68{\pm}0.80$, $0.95{\pm}0.17%$). When Re-188 sulfur colloid was injected to synovial space of rabbit, the uptake in other organs except knee was very low. Conclusion: Re-188 sulfur colloid showed high labeling efficiency, stability and potency for clinical use.

Background : The occurrence of lung complications after allogenic bone marrow transplantation(BMT) has been reported as 40-60 percent. The risk factors for lung complications are whole body irradiation, high dose chemotherapy, graft versus host disease, old age and CMV infection. The prevalence of graft versus host disease is less in Korea than in Western countries, but frequency of CMV infection is higher. Therefore, the pattern of lung complications may be different in Korea from those in Western countries. Methods : A retrospective cohort study was performed on one hundred consecutive adult patients who underwent allogenic bone marrow transplantation from December, 1993 to May, 1999 at Asan Medical Center. Lung complications were divided into two groups by the time of development, within 30days (pre-engraftment) and beyond 30 days (post-engraftment), and then subdivided into infectious and non-infectious complication. Infectious complications were defined as having the organism in blood, BAL fluid, pleural fluid or sputum, or compatible clinical findings in patients, which improved with antibiotics or an anti-fungal therapy. Result: 1) Eighty three episodes of lung complications had occurred in 54 patients. 2) Within thirty days after BMT, non-infectious complications were more common than infections, but this pattern was reversed after 30 days. After one year post-BMT, there was no infectious complication except in cases of recurrence of underlying disease or development of chronic GVHD. 3) Among the non-infectious complications, pleural effusion (27 episodes) was most common, followed by pulmonary edema (8 episodes), bronchiolitis obliterans(2 episodes), diffuse alveolar hemorrhage (1 episode) and bronchiloitis obliterans with organizing pneumonia (1 episode). 4) The infectious complications were pneumonia (bacterial: 9 episodes, viral: 4 episodes, fungal : 5 episodes, pneumocystis carinii : 1 episode), pulmonary tuberculosis(3 episodes) and tuberculous pleurisy (3 episodes). 5) Lung complications were more frequent in CMV positive patients and in patients with delayed recovery of neutrophil count. 6) The mortality was higher in the patients with lung complications. Conclusion : Lung complications developed in 54% after allogenic BMT and were associated with higher mortality.

Background: It has been well documented that transient occlusion of the coronary artery causes myocardial ischemia and finally cell death when ischemia is sustained for more than 20 minutes. Extensive studies have revealed that ischemic myocardium cannot recover without reperfusion by adequate restoration of blood flow, however, reperfusion can cause long-lasting cardiac dysfunction and aggravation of structural damage. The author therefore attempted to examine the effect of postischemic reperfusion on myocardial ultrastructure and to determine the rationales for recanalization therapy to salvage ischemic myocardium. Materials and methods: Young Holstein-Friesian cows(130∼140 Kg body weight; n=40) of both sexes, maintained with nutritionally balanced diet and under constant conditions, were used. The left anterior descending coronary artery(LAD) was occluded by ligation with 4-0 silk snare for 20 minutes and recanalized by release of the ligation under continuous intravenous drip anesthesia with sodium pentobarbital(0.15 mg/Kg/min). Drill biopsies of the risk area (antero-lateral wall) were performed at just on reperfusion(5 minutes), 1-, 2-, 3-, 6-, 12-hours after recanalization, and at 1-hour assist(only with mechanical respiration and fluid replacement) after 12-hour recanalization. The materials were subdivided into subepicardial and subendocardial tissues. Tissue samples were examined with a transmission electron microscope (Philips EM 300) at the accelerating voltage of 60 KeV. Results: After a 20-minute ligation of the LAD, myocytes showed slight to moderate degree of ultrastructural changes including subsarcolemmal bleb formation, loss of nuclear matrix, clumping of chromatin and margination, mitochondrial destruction, and contracture of sarcomeres. However, microvascular structures were relatively well preserved. After 1-hour reperfusion, nuclear and mitochondrial matrices reappeared and intravascular plugging by polymorphonuclear leukocytes or platelets was observed. However, nucleoli and intramitochondrial granules reappeared within 3 hours of reperfusion and a large number of myocytes were recovered progressively within 6 hours of reperfusion. Recovery was apparent in the subepicardial myocytes and there were no distinct changes in the ultrastructure except narrowed lumen of the microvessels in the later period of reperfusion. Conclusions: It is likely that the ischemic myocardium could not be salvaged without adequate restoration of coronary flow and that the microvasculature is more resistant to reversible period of ischemia than subendocardium and subepicardium. Therefore, thrombolysis and/or angioplasty may be a rational method of therapy for coronarogenic myocardial ischemia. However, it may take a relatively longer period of time to recover from ischemic insult and reperfusion injury should be considered.
