  • Malaria is one of the most widespread infectious diseases of tropical countries with an estimated 207 million cases globally. In India, there are endemic pockets of this disease, including Aligarh. Hundreds of Plasmodium falciparum and P. vivax cases with severe pathological conditions are recorded every year in this district. The aim of this study is to find out changes in liver enzymes and kidney markers. Specific diagnosis for P. falciparum and P. vivax was made by microscopic examination of Giemsa stained slides. Clinical symptoms were observed in both of these infections. Liver enzymes, such as AST, ALT, and ALP, and kidney function markers, such as creatinine and urea, were estimated by standard biochemical techniques. In Aligarh district, P. vivax, P. falciparum, and mixed infections were 64%, 34%, and 2%, respectively. In case of P. falciparum infection, the incidences of anemia, splenomegaly, renal failure, jaundice, and neurological sequelae were higher compared to those in P. vivax infection. Recrudescence and relapse rates were 18% and 20% in P. falciparum and P. vivax infections, respectively. Liver dysfunctions and renal failures were more common in P. falciparum patients, particularly in elderly patients. Artesunate derivatives must, therefore, be introduced for the treatment of P. falciparum as they resist to chloroquine as well as sulfadoxine-pyrimethamine combinations.

  • Toxoplasma gondii atypical type II genotype was diagnosed in a pet peach-faced lovebird (Agapornis roseicollis) based on histopathology, immunohistochemistry, and multilocus DNA typing. The bird presented with severe neurological signs, and hematology was suggestive of chronic granulomatous disease. Gross post-mortem examination revealed cerebral hemorrhage, splenomegaly, hepatitis, and thickening of the right ventricular free wall. Histologic sections of the most significant lesions in the brain revealed intralesional protozoan organisms associated with malacia, spongiform changes, and a mild histiocytic response, indicative of diffuse, non-suppurative encephalitis. Immunohistochemistry confirmed the causative organisms to be T. gondii. DNA isolated from the brain was used to confirm the presence of T. gondii DNA. Multilocus genotyping based on SAG1, altSAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico markers demonstrated the presence of ToxoDB PCR-RFLP genotype #3 and B1 gene as atypical T. gondii type II. The atypical type II strain has been previously documented in Australian wildlife, indicating an environmental transmission route.

  • Aujeszky's disease virus(ADV) was inoculated intranasally into the Korean native goats to investigate pathological findings and pathogenesis of ADV infection by using of histological and immunohistochemical methods and in situ hybridization(ISH). Clinical signs of salvation, pyrexia, pruritus and staggering were followed by death with five days after inoculation, Pathoanatomical findings were edema of the lung and the urinary bladder with hemorrhage and congestion, petechial hemorrhages on the endo-and epicardium, renal congestion, moderate splenomegaly and cystic edema. Main microsocpic lesions observed in all infected goats were confined to the CNS and charcterized by perivascular cuffing with lymphocytes and macrophages, focal gliosis, neuronal degeneration and necrosis, and intranuclear inclusion bodies in the neurons and glial cells. Positive reactions to ADV were detected more frequently in the nuclei than in the cytoplasms of infected nerve cells in the CNS by immunohistochemistry and ISH. Frequenctly localized sites of ADV in the CNS were olfactory bulb, prietal cortex, callosal sulcus and corpus callosum. Positive reactions were also detected in the tonsillar epithelium, and alveolar macrophage and sloughed epithelium of the lung.

  • A 4-year-old female Shunauzer dog was referred to the Veterinary Teaching Hospital of Chungbuk National University due to anorexia and depression. The dog had a history of regular walking on grass fields, weight loss, and hyperthermia $(40.6^{\circ}C)$. In the physical examination, lymph node enlargement was confirmed. Complete blood count result revealed leukocytosis and thrombocytopenia but there was no decreasing of red blood cells. On blood chemistry, serum ALP, GGT, CPK, and LDH were elevated. Abdominal radiograph showed splenomegaly. Anaplasma platys infection was suspected with inclusion body-like substances in platelets on blood smear. Anaplasma platys was confirmed by PCR. On the basis of laboratory examination, final diagnosis was anaplasmosis. Treatment was followed for 3 months with tetracycline and doxycycline. The patient was monitored every week during the treatment. The patient has recovered to normal condition without any clinical signs. We are going to emphasize the need of PCR technique in diagnosis and to report the possibility of long term treatment more than two months in rickettial disease.

  • Malaria due to Plasmodium vivax had been known as an indigenous protozoan disease in Korea. However, massive use of insecticides and improvement of sanitation for several decades have led to rapid reduction of malaria incidence, then it was recognized to have been almost eradicated in recent years. However in 1993, one case was reported in Phajoo, Kyungki-do, and then, reported cases have been increasing annually. Recently we encountered one case of malaria in a 3 year old male child living in Dorim-dong, Seoul, who had never been abroad and had no history of transfusion, drug abuse, and travel to endemic area in Korea. He had characteristic fever, chill and splenomegaly and was confirmed as Plasmodium vivax malaria with peripheral blood smear finding. He was successfully treated with hydroxy chloroquine and primaquine. We report this case with brief review of related literature.

  • This is an attempt to evaluate normal spleen size in the Koreans. Spleen scans were obtained in 29 patients who were admitted to the Seoul National University Hospital because of trivial illnesses. All scans were performed by use of $^{51}Cr$-labelled, heat-treated erythrocyte. As a simple screening criteria for the presence of splenomegaly, vertical height of the spleen was considered to be the best one. After statistical analysis it was concluded that the upper limit of normal spleen height is 13cm in anterior view and 14cm in lateral view.

  • Gaucher disease (GD, OMIM #230800 OMIM#230800) is a rare, autosomal recessive inherited metabolic disorder caused by mutation in GBA1 encoding the lysosomal enzyme, glucocerebrosidase. The deficiency of glucocerebrosidase leads to an accumulation of its substrate, glucosylceramide in macrophages of various tissues. Common clinical manifestations include cytopenia, splenomegaly, hepatomegaly, and bone lesions. The phenotype of GD is classified into three clinical categories: Type 1 (non-neuronopathic) is characterized by involvements on the viscera, whereas types 2 and 3 (neuronopathic) are associated with not only visceral symptoms but also neurological impairment, either severe in type 2 or variable in type 3. A diagnosis of GD can be confirmed by demonstrating the deficiency of acid glucocerebrosidase activity in leukocytes. Mutations in the GBA1 should be identified as they may be of prognostic value in some cases. Biomarkers including Chitotriosidase, CCL18, and glucosylsphingosine (lyso-GL1) are useful in diagnosis and treatment monitoring. Currently available disease-specific treatment in Korea consists of intravenous enzyme replacement therapy and substrate reduction therapy. For enhancing long-term prognosis, the onset of Parkinson's disease and Lewy body dementia, or the occurrence of a blood disease or cancer (hepatocellular carcinoma) should be monitored in older patients. The development of new strategies that can modify the neurological phenotype are expected, especially in Asia including Korea, where the prevalence of neuronopathic GD is relatively higher than that in western countries.

  • Feline chronic lymphocytic leukemia (CLL) is a rare disease. Its diagnosis is not simple because of the absence of clinical signs and the presence of mature lymphocytosis. An 11-year-old female spayed Russian Blue cat was referred to the veterinary medical teaching hospital for lethargy, diarrhea, weight loss, and inappetence. Marked lymphocytic leukocytosis and a significantly increased number of small-to-intermediate-sized lymphocytes in the peripheral blood were found on hematological examination. The results of the feline leukemia virus and immunodeficiency virus test were negative. Further, mild splenomegaly was detected. Bone marrow aspirate analysis revealed mature lymphocytosis and a clonally rearranged T cell receptor gene with the polymerase chain reaction (PCR) for antigen receptor rearrangement assay. Flow cytometric immunophenotyping showed a homogeneous population of CD5+/CD21-T-cells in the peripheral blood and bone marrow. According to the results of the aforementioned examinations, CLL was diagnosed. Treatment was not initiated at the time of diagnosis because the clinical signs were mild and did not affect the quality of life. This report describes the clinical findings and use of advanced diagnostic tools such as molecular clonality analysis and immunophenotyping for the diagnosis of feline CLL.

  • Two 11-year-old cats, female Korean shorthair cat and male Siamese cat, with abdominal distention were presented to the local animal hospitals. Radiographic and ultrasonographic examinations revealed moderate to severe splenomegaly in both cats. In Korean shorthair cat, multiple masses were also existed on the anal and facial skin. Surgically excised whole spleens of two cats were requested for histopathologic examination. Histopathologically, numerous neoplastic round cells with cytoplasmic fine granules were widely infiltrated in the splenic parenchyma. The cytoplasmic granules were metachromatic on toluidine blue staining. These splenic masses were diagnosed as splenic mast cell tumors. Among them, Korean shorthair cat was remained healthy for at least 1 year after splenectomy. Because of no visiting of owner, we were only able to know the information for Siamese cat until 10 months after the splenectomy. To our best knowledge, this is the first detail case reports for splenic mast cell tumors in cats in Korea.

  • A 7-year-old neutered male, domestic shorthair cat presented anorexia and lethargy. The complete blood cell count revealed severe non-regenerative anemia, lymphocytic leukocytosis, neutropenia, and thrombocytopenia. On the peripheral blood smear examination, medium to large lymphoblastic cells with moderate amounts of basophilic cytoplasm were observed in up to 70% of peripheral leukocytes. Feline leukemia and immunodeficiency viruses were not detected using a commercial diagnostic kit. While splenomegaly and blunt margins of the caudoventral liver were observed in abdominal radiography, changes in the intra-abdominal lymph nodes were not remarkable. Ultimately, flow cytometric immunophenotyping from the peripheral blood revealed a negative for B-cell markers (CD21-/CD79a-) and T-cell markers (CD3-/CD4-/CD5-/CD8-). Based on the hematological examination and the immunophenotyping assay, the cat was diagnosed with non-B, non-T acute lymphoblastic leukemia. Here, we report a rare case of non-B, non-T acute lymphoblastic leukemia to raise awareness and provide information on clinical symptoms and laboratory test and immunophenotyping analysis results.
