A 1-year-old, intact female, Yorkshire terrier was referred with diarrhea and depression. Fecal examination indicated overgrowth of yeast-like organisms. CBC and blood smear revealed severe leukemoid reaction with degenerative changes of neutrophils. Radiographic examination showed decreased serosal detail and organomegaly, suggesting pyometra with peritonitis. Thus, the dog was suspected as pyometra with peritonitis. Culture and molecular analysis of the yeast-like organisms revealed that overgrown yeast was Candida parapsilosis.

Airflow in the nasal cavity of a normal Korean adult is investigated experimentally by tomographic PIV measurement. Knowledge of airflow characteristics in nasal cavities is essential to understand the physiology and pathology aspects of nasal breathing. Several studies have utilized physical models of the healthy nasal cavity to investigate the relationship between nasal anatomy and airflow. All of these researches on nasal airflow are under the condition of constant flow-rate. In this study, nasal cavity flow with the physiological period is investigated by tomographic PIV, for the first time. A pumping system that can produce the periodic flow is created. Thanks to a new method for the model casting by a combination of the rapid prototyping and curing of clear silicone, a transparent rectangular box containing the complex nasal cavity can be made for PIV, The CBC PIV algorithm is used for analysis. Phase-averaged mean and RMS velocity distributions are obtained for inspirational and expiration nasal airflows. The comparison with the constant flow case is appreciated. There exist many flow patterns depending on each phase.

A 8-year-old spayed female Korean short-haired cat was presented with respiratory distress. CBC, serum chemistry analysis, plain radiography, and abdominal ultrasonography were performed. Besides hypertrophic cardiomyopathy (HCM) suspected by the thoracic radiograph, a tubular, tortuous soft tissue structure was detected at the region of the left retroperitoneal cavity on the abdominal radiograph. On the abdominal ultrasonography, a shunt vessel is identified caudo-lateral to the left kidney region. These findings are consistent with spleno-systemic shunts in cats. Furthermore, portal hypertension and diffuse hepatic lesion were also identified. Although the cause of a shunt vessel is not easy to diagnose, it is important to include spleno-systemic shunt into differential diagnosis list, when convoluted, tubular soft tissue opacity is seen on the digital radiography (DR). This report will allow clinicians to raise awareness of complications of portosystemic shunt (PSS) and better treat PSS suspected feline patients when the advanced modalities such as computed tomography and magnetic resonance imaging are not available.

A 7-year-old female American cocker spaniel presented with chronic regurgitation and megaesophagus on radiography at a local hospital. Dry and coarse hair coat, tail alopecia, and bradycardia were observed during physical examination. Mild, non-regenerative anemia was indicated by complete blood count (CBC) analysis. Concurrent hypercholesterolemia and hypertriglycemia were indicated by biochemistry tests. Decreased levels of total and free thyroxine (T4) and increased canine thyroid stimulating hormone (cTSH) levels were also detected. Megaesophagus was confirmed by radiographic examination. Based on the results, a diagnosis of hypothyroidism with megaesophagus was made. The patient was initially treated with levothyroxine sodium at a dosage of 0.02 mg/kg twice a day. After two weeks of treatment for hypothyroidism, the dilated esophagus returned to its original size and no further regurgitation was observed. No relapse was observed during two months of follow-up.

The aim of this study was to evaluate the safety and effects of a soy lecithin-based supplement on the general health, skin condition, and blood lipid levels of dogs. Twenty-five, healthy, privately-owned dogs were enrolled in the study. Oral supplementation was administered for 8 weeks in the treatment group. Evaluation items included a thorough physical examination, owner responses to a questionnaire, blood analysis (CBC, CRP, serum chemistry, lipid profile). The results showed a significant improvement in amount of exercise, water intake, skin exfoliation in the treatment group (P < 0.05) but no significant changes in the other evaluation items, including no significant changes in blood component results following administration of the supplement. Most dogs well tolerated the treatment, and there were no serious adverse events. We suggest that soy lecithin has potential as a nutraceutical for the positive effect of general health condition such as activity and skin condition. Further studies are needed to establish the appropriate dose level and administration frequency of soy lecithin in dogs.

Objectives: This case is significant as a rare observational record at the Korean medical practice field. This case reports progression of co-administration of Korean herbal medicines and conventional medicines for cough in patients with myocardial infarction relapse suspected of developing acute respiratory infection. Methods: First, the chest radiography, CBC count and urinalysis were performed to estimate patient's systematic condition. After the estimated diagnosis, the patient was treated with modified Dingchuan decoction, antibiotics, and complex syrup for cough. We used the Cough-Specific Quality-of-Life Questionnaire (CQLQ) to assess patient's respiratory symptoms. Results: Co-administration of Korean herbal medicines and conventional medicines resulted improving of cough and sputum symptoms. Laboratory analysis items and total score of CQLQ also showed significantly improved results. Adverse effects were not observed. Conclusions: In this case, we concluded that co-administration of Korean herbal medicine and conventional medicine may be an effective therapy for the treatment of cough in patients with myocardial relapse of developing acute respiratory infection.

In this paper, we introduce two forgery attacks on the PMAC. If it has no truncation then the attack requires about $2^{n}$ 2+1/ chosen texts, otherwise, the attack requires about $2^{n}$ 2+1/ chosen texts and $2^{n-}$$\tau$ MAC verifications where $\tau$ is the size of the MAC. We also give a forgery attack on the TMAC variant which requires about $2^{n}$ 2+1/ texts.

The main purpose of this study was to examine the correlation between the consumption of red ginseng-based 'SSR' for 30 days and the reduction in human fatigue, blood component changes, and immune cell activity in 35 human subjects. 'SSR' is composed of zinc oxide, folic acid, and D-α-tocopherol with red ginseng as the main component. According to the protocol criteria of the study, 35 subjects who understood the purpose of the study and signed an informed consent form were selected. The fatigue survey was conducted through a questionnaire, and after taking 'SSR', a decreased tendency of physical, mental, and neurosensory fatigue was observed. In hematological analysis, no significant changes were observed in the levels of WBC, RBC, and hemoglobin; however, AST (SGOT) and ALT (SGPT) levels were statistically significantly decreased. In immunological analysis, it was observed that the proliferative effect of T cells (CD3+CD4+) was greater than that of NK cells (CD16+CD56+). The collected data were subjected to t-test analysis using the SPSS 25.0 statistical program. The result from this study proposes that 'SSR' can be used as a functional food material as it reduces human fatigue and enhances immune function.

A 1-year-old, female English cocker spaniel (ECS) dog was presented with 3-month history of vomiting and retaking of the vomitus, and chronic weight loss. The client had noticed mild abdominal distension 10 days before. The dog was diagnosed as chronic hepatitis with hepatic cirrhosis based on complete blood count (CBC), serum chemistry profiles, radiography, ascites assessment, bile acid evaluation, and liver biopsy through exploratory laparotomy and necropsy. CBC and serum chemistry profiles revealed mild anemia, slightly elevated hepatic enzymes (ALT and AST), increased creatinine kinase (CK), hyperammonemia, and hypoproteinemia with hypoalbuminemia. Ascites was transudate according to analysis of components. Bile acid assessment (fasting; $174.4{\mu}mol/L$ and postprandial; $198.4{\mu}mol/L$) showed strongly suspected hepatic insufficiency. On radiological findings, ascites was evident. Atrophied liver (especially left side lobes) and distended mesenteric vasculatures were observed by exploratory laparotomy. Histopathological examination of marginal lesion of left lateral lobe of liver by biopsy revealed the necrosis of hepatic cells, dilation of sinusoids, infiltration of neutrophils in sinusoids, and vacuolation of hepatic cytoplasm. The patient had been managed with careful low protein diet and specific supportive therapy (ursodeoxycholic acid, prednisolone, vitamine E, and interferon). Vomiting and ascites disappeared with medical management. The dog was monitored periodically by CBC, serum chemistry and radiographic examination. The dog survived more 18 months with medical therapy. After spontaneous death, necropsy and histopathologic examination were performed.

Background : The diagnosis of emphysema during life is based on a combination of clinical, functional, and radiographic findings, but this combination is relatively insensitive and nonspecific. The development of rapid, high-resolution third and fourth generation CT scanners has enabled us to resolve pulmonary parenchymal abnormalities with great precision. We compared the chest HRCT findings to the pulmonary function test and arterial blood gas analysis in pulmonary emphysema patients to test the ability of HRCT to quantify the degree of pulmonary emphysema. Methods : From october 1994 to october 1995, the study group consisted of 20 subjects in whom HRCT of the thorax and pulmonary function studies had been obtained at St. Mary's hospital. The analysis was from scans at preselected anatomic levels and incorporated both lungs. On each HRCT slice the lung parenchyma was assessed for two aspects of emphysema: severity and extent. The five levels were graded and scored separately for the left and right lung giving a total of 10 lung fields. A combination of severity and extent gave the degree of emphysema. We compared the HRCT quantitation of emphysema, pulmonary function tests, ABGA, CBC, and patients characteristics(age, sex, height, weight, smoking amounts etc.) in 20 patients. Results : 1) There was a significant inverse correlation between HRCT scores for emphysema and percentage predicted values of DLco(r = -0.68, p < 0.05), DLco/VA(r = -0.49, p < 0.05), FEV1(r = -0.53, p < 0.05), and FVC(r = -0.47, p < 0.05). 2) There was a significant correlation between the HRCT scores and percentage predicted values of TLC(r = 0.50, p < 0.05), RV(r = 0.64, p < 0.05). 3) There was a significant inverse correlation between the HRCT scores and PaO2(r = -0.48, p < 0.05) and significant correlation with D(A-a)O2(r = -0.48, p < 0.05) but no significant correlation between the HRCT scores and PaCO2. 4) There was no significant correlation between the HRCT scores and age, sex, height, weight, smoking amounts in patients, hemoglobin, hematocrit, and wbc counts. Conclusion : High-Resolution CT provides a useful method for early detection and quantitating emphysema in life and correlates significantly with pulmonary function tests and arterial blood gas analysis.
