Cultural method, dark field microscopy & fluorescent antibody technique were compared for their sensitivity of the detection of leptospires from experimentally infected mice. Two groups of mice were infected with L. icterohemorrhagiae (M20) and L. australis (Ballico), and the infected blood, urine and a number of organs were subjected to the bacterial isolation. The results obtained were summarized as follows: 1. L. icterohemorrhagiae (M20) and L. australis (Ballico) in blood, urine and various tissues of experimentally infected mice were detected with a negrigible non specificity, by the fluorescent antibody technique. 2. The fluorescent antibody technique, as applied to detection of leptospires in blood, urine and various infected tissue, proved to be better than cultural method and dark-field microscopy. 3. Early detection of leptospires by fluorescent antibody technique were possible in blood at 2 days after inoculation, whereas detection of organisms in liver, spleen, lung and kidney were observed later. By means of fluorescent antibody technique, the detection of leptospires in kidney and urine was possible up to 34 days postinoculation, whereas those in other parts were impossible. 4. Fluorescent antibody reaction of leptospires were highly specific to homologous antigen rather than to heterologous one. 5. Fluorescent antibody technique may be of value in the application for the demonstration of leptospira from clinical specimens.

Alkaptonuria (AKU, OMIM: 203500) is a rare autosomal recessive disorder of tyrosine metabolism due to a defect of enzyme activity, homogentisate 1,2-dioxygenase (HGD). The patients with AKU initially presented with dark urine discoloration, and ochronosis and arthritis develop after third decades of life. With advances of Internet resources, web-based health seekers for rare disease are increasing. Here, we report the case of an 18-year-old boy with AKU who visited our center due to dark black urine based on self-diagnosis via web searching of this rare condition. Compound heterozygous mutations in HGD gene, IVS5+3A>C and IVS12+6T>C were identified and both of mutations were detected in his parents. Our case illustrates the utility of publicly available Internet resources for diagnosis of rare disease.

An aged (14 years old) female snow leopard exhibited renal calculi and pyelonephritis at necropsy. The animal experienced appetite loss, mild diarrhea, polydipsia, and difficulty breathing, and was curled up and staggering on its hind legs 2 days before death. Large calculi were found obstructing both sides of the renal pelvis. The left-side calculus was larger than that of the right side. These calculi had rough surfaces and were $15{\times}21mm$ and $9{\times}14mm$, respectively. The bladder was filled with dark, cloudy urine. Multiple ulcerous lesions were found in the inner layer of the bladder. Enterococcus faecalis and Proteus mirabili were identified via microbiological examination of the urine. Under microscopic examination, urine struvites were observed in the pyuria sediment in the bladder. To our knowledge, this is the first documented case of nephrolithiasis in a captive snow leopard.

Alkaptonuria is a rare metabolic disease in which homogentisic acid cannot be metabolized due to a lack of the enzyme homogentisic acid oxidase. The disease often manifests itself in childhood by darkening of the urine upon standing. The disease leads to such serious consequences as ochronosis of cartilage and connective tissues with arthritis. It is expected that treatment with ascorbic acid and a dietary restriction of protein may decrease the late and serious consequences by diminishing the serum concentration of the metabolite benzoquinone acetic acid. A thirteen month-old girl was recently diagnosed with alkaptonuria by urine organic acid analysis. She excreted pinkish urine on a diaper and as time went by the urine color changed to a light brown. In laboratory findings, urine examination and culture results were normal. But urine organic acid analysis detected abnormal findings a prominent and massive elevation of homogentisic acid. The other physical findings were normal. This is the first case diagnosed in Korea.

Ten sheeps from one farm had sudden onset of anorexia, jaundice and hemoglobinuria and died within 3 days after showing clinical signs during 3 months period. Postmortom examination was performed on one case and copper concentrations in the livers kidney and serum of the necmpsied minim were analysed. Grossly, the conjunctive, subcutaneous tissue and abdominal fat were generally icteric. The liver was enlarged with yellowish orange in color. The kidney was enlarged with dark red in color and the urinary bladder was filled with dark red urine. Histopathologically, centrilobular hepatocellular necrosis, neutrophilic infiltrations bile stasis and aggregation of fine granules-laden macrophages in the portal area were noted in the liver. Most of the Bowman's spaces and renal tubules were filled with homogenous eosinophilic fluid. Extramedullary hematopoiesis was noted in the submandibular lymph node. Copper concentrations in serum, liver and kidney of the necropsied animal were 25.0, 2732.8 and 471.3 ppm respectively. Based on the gross and histopathological findings and the high copper concentrations in the organs, this case was diagnosed as chronic copper toxicosis. Possible etiology on this outbreak is also discussed.

Objectives: The purpose of this case report is to describe the efficacy of Saenggan-tang-gagam treatment in a patient with immune-tolerant chronic hepatitis B who converted to the immune active phase during hospitalization for Intracerebral hemorrhage. Methods: A 61-year-old male patient with chronic hepatitis B was hospitalized from July 21, 2016 to October 24, 2016. On September 5, the patient showed fatigue and dyspepsia, and his urine was dark. These symptoms were accompanied by a dramatic elevation of aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT) levels. Saenggan-tang-gagam was administered three times a day until the patient was discharged from the hospital. Results: After the Saenggan-tang-gagam treatment, AST and ALP levels decreased significantly, below the upper limit level. In addition, the levels of ALT and GG were significantly decreased. In addition, the fatigue, dyspepsia, and dark urine induced by hepatitis improved after the Saenggan-tang-gagam treatment. Conclusion: This case report suggests that traditional Korean medicine has a beneficial effect on the immune active phase of chronic hepatitis B.

So-gal(消渴) is a oriental medical pathologic state that is characterized by 3 major symptoms - thirst, polyphasia, polyuria - of which especially thirst features Sang-so(上消). Diabetes mellitus and So-gal(消渴) have many points in common. But there are considerable differencies between them, because they have obviously different diagnostic bases from each other. That is, oriental medicine places more weight on symptoms than clinopathologic laboratory reports. This case of stroke patient complained of severe thirst and additional dryness in the mouth, choking sensation in the chest, hidrosis, insomnia, dark colored urine, constipation. The patient had no clinical history of diabetes mellitus. Based on oriental medical standards, we diagnosed the case as Sang-so(上消). Several herbal medicines were dispensed for 48 days. And considerably effective result were obtained. Object : 1 case of stroke patient who complained severe thirst. Medication : . Seonghyangjeonggisan for 5 days (2000. 6. 9 - 6. 13.) . Paljeongsan for 21 days (2000. 6. 14. -7. 5) . Ikwonsan for 8 days (2000. 7. 6 - 7. 13) . Okcheonsan for 14 days (2000. 7. 14 - 7. 27) Result : 1. After administration of Paljeongsan, dark colored urine turned normal. 2. After administration of Ikwonsan, dryness in the mouth improved. 3.

Recently, the miniaturization and digitalization for the inspection devices of point-of-care testing (POCT) are rapidly evolving. In the urine test, a lot of researches on index paper technology are being conducted because people can be self-diagnosed through visual color comparison using a urine test paper, Dipsick. The purpose of this study is to analyze the RGB values from the color changes on Dipstick Pad, which isused for urine test, using a smartphone camera. To this end, the primary, analytes in urine wasdiabetes-related parameters such as glucose, ketone body and pH, which is the most frequently tested elements, and we pursuited to quantify the changes in dipstick color caused from artificial urine containing different ranges of sugar, ketone body, and pH. In this experiment, changes in RGB values under bright and dark illuminances were compared, and changes in RGB value were monitored as a function of concentration of analytes under the ambient illumination of laboratory. As a result, color separation at the bright luminance region was good, but it did not appearat the low luminance region, and the changed profiles in RGB value under different illuminances was suggested to correct the problem of the color separation algorithm.

The principal significance of the urothelial changes caused by polyomavirus activation is in an erroneous diagnosis of urothelial cancer; however, the clue to their benign nature is the smooth structureless nuclear configuration and the relative paucity of affected cells. Though virologic studies and electron microscopy are usually needed to firmly establish the diagnosis, cytology is the most readily available and rapid means of establishing a presumptive diagnosis of human polyomavirus infection. A urine specimen of a 24-year-old man with hemorrhagic cystitis beginning two months after bone marrow transplantation for acute myeloblastic leukemia(M2) was submitted for cytologic evaluation. Cytologic findings revealed a few inclusion-bearing epithelial cells intermingled with erythrocytes, neutrophils, lymphocytes, and macrophages. Most of the inclusion-bearing fells had large, round to ovoid nuclei almost completely filled with homogeneous dark, basophilic inclusion. The chromatin was clumped along the periphery and the cytoplasm was mostly degenerated. The other cells exhibited irregular inclusions attached to the nuclear membrane surrounded by an indistinct halo. These findings were consistent with polyomavirus infection.
