A Korean domestic short hair (1-year-old, male) presented with 2 to 3 weeks of seizures, aggressive behavior, vomiting, anorexia, and lethargy. The frequency of seizure had gradually increased from once a week to once every 3 hours. Physical and neurologic examination, diagnostic screening tests, including complete blood count (CBC), serum chemistry, electrolyte, coagulation test, X-ray, ultrasonography, and urinalysis were performed. Feline Leukemia Virus (FeLV), Feline Immunodeficiency Virus (FIV) and Toxoplasma spp. All tested negative, but the Feline Corona Virus (FCoV) kit revealed a positive result. To determine the exact diagnosis, magnetic resonance imaging (MRI) was performed but yielded no specific findings. The patient was then diagnosed with idiopathic epilepsy and treatment of phenobarbital was initiated. A month's treatment with phenobarbital proved ineffective as symptoms worsened. Zonisamide was then selected as an additional anticonvulsant. After adding zonisamide, symptoms improved, and seizures abated for 15 months. This is the first case report in South Korea describing the use of phenobarbital and zonisamide in the treatment of a cat with idiopathic epilepsy.

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.

Superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) play crucial roles in balancing the production and decomposition of reactive oxygen species (ROS) in living organisms. These enzymes act cooperatively and synergistically to scavenge ROS. In order to imitate the synergism of these enzymes, we designed and synthesized a novel 32-mer peptide (32P) on the basis of the previous 15-mer peptide with GPX activity and a 17-mer peptide with SOD activity. Upon the selenation and chelation of copper, the 32-mer peptide was converted to a new Se- and Cu-containing 32-mer peptide (Se-Cu-32P) that displayed both SOD and GPX activities, and its kinetics was studied. Moreover, the novel peptide was demonstrated to be able to better protect vero cells from the injury induced by the xanthine oxidase (XOD)/xanthine/$Fe^{2+}$ damage system than its parents. Thus, this bifunctional enzyme imitated the synergism of SOD and GPX and could be a better candidate of therapeutic medicine.

To find antitumor components of Lyophyllum decastes, the mycelia of L. decastes were cultured in artificial media and a new antitumor component which showed potent antitumor activity against sarcoma 180 implanted in mice, was isolated and named 'Lyophyllan A'. Lyophyllan A was composed of a polysaccharide moiety (86%) and a protein moiety (2%). The polysaccharide moiety was found to be a heteroglycan which consisted of glucose (48.1%), mannose (30.8%), galactose, xylose and fucose. The protein moiety contained 18 amino acids. Cultural characteristics of L. decastes were investigated by shake culture method. The best result was obtained when L. decastes was cultured in medium glucose 50g, peptone 10g, corn steep liquor 30ml, $KH_2PO_4$ 0.87g, $MgSO_4$ $7H_2O$ 0.5g, $CaCl_2$ 0.3g, $FeSO_4{\cdot}7H_2O$ 10mg, $MnCl_2{\cdot}4H_2O$ 7mg, $ZnSO_4{\cdot}7H_2O$ 4mg and $CuSO_4{\cdot}5H_2O$ 1mg per one liter at $26^{circ}C$, 180rpm, for 9 days.

Myocardial tagging technique such as spatial modulation of magnetization (SPAMM) allows the study of myocardial motion with high accuracy. However, the accuracy of the estimation of tag intersection can be affected by tagline spacing. The aim of this study was to investigate the relationship between tagline spacing of SPAMM image and tagging contrast-to-noise ratio (CNR) in in-vivo study. Two healthy volunteers were undergone electrocardiographically triggered MR imaging with SPAMM-based tagging pulse sequence at a 1.5T MR scanner. Horizontally modulated stripe patterns were imposed with a range from 3.6 to 9.6 mm of tagline spacing. Images of the left ventricle(LV) wall were acquired at the mid-ventricle level during cardiac cycle with FE-EPI (TR/TE = 5.8/2.2 msec, FA= 10$^{\circ}$. Tagging CNR for each image was calculated with a software which developed in our group. During contraction, tagging CNR was more rapidly decreased in case of narrow tagline spacing than in case of wide tagline spacing. In the same heart phase, CNR was increased corresponding with tagline spacing. Especially, at the fully contracted heart phase, CNR was more rapidly increased than the other heart phases as a function of tagline spacing. The results indicated that the optimization of tagline spacing provides better tagging CNR in order to analyze the myocardial motion more accurately.
