Objectives: This study aimed to introduce a clinical case of asymptomatic microhematuria due to suspicion of kidney trauma following a motor vehicle accident. Methods: A 19-year-old male was hospitalized with the chief complaint of back pain after a motor vehicle accident. He showed an elevated urine red blood cell (RBC) level in the laboratory test, although no specific traumatic lesions were present on the body. He was assessed to have asymptomatic microhematuria, and Zhu Ling Tang (polyporus decoction) was given to him to be taken three times daily. Results: After the treatment, the level of urine red blood cells returned to normal range. Adverse events were not observed. Conclusions: Zhu Ling Tang caused a short-term improvement in the urinalysis levels of a patient with asymptomatic hematuria. However, further studies are needed, as this study is only a single-case report.

In this study, imported ornamental goldfish (Oranda and black moor) with high mortality was investigated with histopathological analysis. Fishes showed clinical symptoms characterized by gill necrosis and cumulative mortality ranging from 60% to 90% within a month after import from Thailand and China in 2021. CyHV-2 was detected in gill, kidney, spleen and liver of goldfishes. Histopathological analysis revealed epithelial necrosis, intranuclear inclusion bodies associated with viral symptoms in epithelial cell, macrophage infiltration and vacuolation in secondary lamella. In addition, disseminated granuloma formation was observed in various organs such as kidney, heart and mesenchymal membranes. These lesions refer to coinfections with CyHV-2 and other pathogens that cause chronic inflammation, which leads to mortality. Therefore, early disease monitoring needs to reduce the mortality when ornamental goldfish is imported.

Rejection is one of the life-threatening complications after organ transplantation. An eight-month-old, intact male, mixed breed dog was presented with acute rejection after renal allograft. The heterotopic renal transplantation with bilateral nephrectomy was performed in the dog. The triple drug protocol for immunosuppression was applied for prevention of the acute rejection. Postoperative care was done according to the transplantation protocol of VMTH, Kangwon National University. The dog was euthanized when the serum creatinine concentration exceeded 5 mg/dL followed by tile signs of illness. The transplanted kidney was enlarged. The renal cortex lesions were characterized by necrosis of the renal tubules and the glomeruli. Interstitial lesions were characterized by hemorrhage and severe infiltration of lymphoid cells. Intrarenal arteries showed necrosis of the walls and infiltration of perivascular lymphoid cells. In immunohistochemical (IHC) findings, infiltration of the CD4 and the CD8 positive T lymphocytes was examined. In this case, acute rejection was shown by humoral and cellular immunity on the basis of histopathologic and IHC evaluation.

In spite of recent progress in anticancer chemotherapy, the survival of patients with metastases to the lung treated nonsurgically has been extremely poor. So we adopted more aggressive surgical approaches for the treatment of patients with pulmonary metastases since 1985. We experienced 22 operations of metastatic lung cancer in 19 patients in the department of Thoracic & Cardiovascular Surgery in Kosin Medical College since 1985, so we reviewed the results of treatment retrospectively. The results were as follows: 1. The primary organs of metastatic lung cancer were 4 cases in each of the breast, uterus, and extremities, 3 cases in the rectum, 2 cases in the kidney, 1 case in each of the pelvis and liver, and the pathological findings were 13 cases in carcinoma and 6 cases in sarcoma. 2. The treatments for primary lesions were 15 cases of the operations with anticancer chemotherapy or radiation therapy, 2 cases of choriocarcinoma with anticancer chemotherapy only, 1 cases of uterine cervical carcinoma with chemo-radiation therapy, and 1 case of pelvic synovia sarcoma with intra-arterial anticancer chemotherapy. 3. Disease free intrerval were as follows: 7 cases were in 2 years to 4 years, 4 cases were in 1 year to 2 years, and 5 cases were beyond one year, of them one case was discovered primary lesion and metastatic lung tumor concomittently. 3 cases were above 4 years, of them one case of breast cancer were above 13 years especially. 4. The sites of metastatic lung cancer was 15 lesions in the right lung, and 9 lesions in the left lung, And the lobar sites were 10 lesions in the upper lobe, 2 lesions in the middle lobe, and 12 lesions in the lower lobe. 5. The operative methods of metastatic lung cancer were 7 case of partial resection of lung, 12 cases of pulmonary lobectomy, 1 case of pneumonectomy and 1 case of dissection of mediastinal lymph node. 6. The postoperative complications were 1 case of mild respiratory insufficency, 1 cases of pyothorax, and 1 case of urethral stricture. 7. Postoperative adjuvant therapy were as follows: No adjuvant therapy were 4 cases, anti-cancer chemotherapy were 8 cases, radiation therapy was 1 case, and combined with chemo k radiation therapy were 8 cases. 8. The results of long term follow-up were as follows: The 5 patients were died at 2 months, 22 months, 24 months, 32 months, and 49 months postoperatively, so mean survival period was 32 months postoperatively excluding one patient who was died at 2 months postoperatively. And 14 patients are aliving, of them 3 patients are living in recurred state, and the other 11 patients are living without any evidence of recurrence.

A 13-year-old male Yorkshire terrier was Presented with Persistent weight loss anorexia and dark brown urine of 3-month duration. On physical examination, a firm oval mass was palpated at left renal region. In hematology and blood chemistry, neutrophilia, anemia, thrombocytopenia and elevation of ALKP were found. Abdominal radiography, ultrasonography and ultrasound-guided percutaneous pyelogram revealed masses originated from left kidney, mildly dilated renal Pelvis and intact ureter. Urinalysis showed hematuria and proteinuria. Because the state of dog became deteriorated during transfusion and the frail renal tumor was suspected to be the cause of inflammation and anemia, nephrectomy was performed. Renal masses, approximately $2{\times}3cm\;and\;5{\times}4cm$ respectively in size, was surrounded by swollen and congested mesentery and ascites. Metastatic lesion was not found in other organs. During recovery, the dog showed cardiopulmonary arrest and did not respond to critical care. Histologically the kidney was affected by necrotic and hemorrhagic change. This hemangiosarcoma most likely arose from the renal parenchyma resulting In diffuse lesions in the kidneys thought to be the cause of chronic anorexia and weight loss.

Atherosclerosis arising from the pro-inflammatory conditions associated with chronic kidney disease (CKD) increases major cardiovascular morbidity and mortality. Rapamycin (RAPA) is known to inhibit atherosclerosis under CKD and non-CKD conditions, but it can cause dyslipidemia; thus, the co-application of lipid-lowering agents is recommended. Atorvastatin (ATV) has been widely used to reduce serum lipids levels, but its synergistic effect with RAPA in CKD remains unclear. Here, we analyzed the effect of their combined treatment on atherosclerosis stimulated by CKD in apolipoprotein E-deficient (ApoE-/-) mice. Oil Red O staining revealed that treatment with RAPA and RAPA＋ ATV, but not ATV alone, significantly decreased the atherosclerotic lesions in the aorta and aortic sinus, compared to those seen in the control (CKD) group. The co-administration of RAPA and ATV improved the serum lipid profile and raised the expression levels of proteins involved in reverse cholesterol transport (LXRα, CYP7A1, ABCG1, PPARγ, ApoA1) in the liver. The CKD group showed increased levels of various genes encoding atherosclerosispromoting cytokines in the spleen (Tnf-α, Il-6 and Il-1β) and aorta (Tnf-α and Il-4), and these increases were attenuated by RAPA treatment. ATV and RAPA＋ATV decreased the levels of Tnf-α and Il-1β in the spleen, but not in the aorta. Together, these results indicate that, in CKD-induced ApoE-/- mice, RAPA significantly reduces the development of atherosclerosis by regulating the expression of inflammatory cytokines and the co-application of ATV improves lipid metabolism.

A total of 18 Newcastle disease virus (NDV) isolates that were recovered from 1949 through 1997 were characterized and pathotyped. All viruses were highly virulent as determined by intracerebral pathogenicity indices ${\geq}1.81$ in day-old. These pathotypes are typical for viscerotropic velogenic NDV (VVNDV) pathotype viruses. Some differences were observed for the chicken red blood cell elution rate and thermostability of the hemagglutinin at $56^{\circ}C$. Three antigenic groups were identified by a hemagglutination-inhibition assay using NDV monoclonal antibodies. And the predominant gross lesions were as follows: discharge from the nasal cavity, tracheal mucus, petechial hemorrhage in the heart fat, kidney urates and hemorrhage with or without necrosis in the gastrointestinal tract. Severe hemorrhagic or necrotic lesions were also noted in the lymphoid organs and were localized primarily in the spleen and cecal tonsil. However, differences in the occurrence and frequency of the gross lesions were observed between the virus strains. Among them, NDV strains that induced neurological symptoms belonged only to genotype VI. This strain had spread throughout Korea during the late 1980s to the 1990s, which suggests that specific VVNDVs genotypes might result in neurological symptoms.

A 9-month-old, castrated, male Labrador Retriever was referred for generalized progressing cutaneous reddish mass lesions with bleeding, scale, crust, and pruritus. On the basis of histopathological findings and the results of immunochemical staining, cutaneous nonepitheliotropic B-cell lymphoma was identified. A cyclophosphamide-doxorubicin-vincristine-prednisolone (CHOP)-based chemotherapy regimen was initiated, and the patient initially showed partial response to vincristine and $\text\tiny{L}$-asparaginase, but the cutaneous lesions progressed gradually. After the first cycle of the CHOP-based protocol, lomustine was administered instead. The cutaneous lesions showed partial response to lomustine, but the treatment did not stop the progression of cutaneous lymphoma. The patient was euthanized due to neurologic signs, including reduced consciousness and seizures, 53 days after initial presentation. The postmortem histopathological examination showed systemic metastasis involving the lymph nodes, skin, kidney, ureter, liver, brain, temporal muscle, diaphragmatic muscle, conjunctiva, and oral cavity.
