Candidiasis is often observed in patients with leukemia, malignant lymphoma and aplastic anemia, all of whom show immunodeficiency. Factors contributing to the increased incidence of candida infections include the overuse of broad-spectrum antimicrobial agents, and the prolonged survival of patients with immunodeficiency. Candida is a major causative organism of nosocomial infection, as are P. aeruginosa and methicillin-resistant Staphylococcus aureus. The number isolated was greater in the order of C. albicans > C. glabrata > C. tropicalis > C. parapsilosis > C. krusei. C. albicans, which was detected most frequency, was isolated from 60-70% of all samples every year. Isolated frequencies of C. albicans were 66-77% from sputum, 43-70% from urine, and 62-72% from vaginal swabs. In regard to annual changes in deep-seated candidiasis among autopsied cases, the incidence reached a peak in the 1985 to 1988 period, and thereafter decreased. The number of cases with infection of the stomach was largest, followed by the esophagus, the lung and kidney. These cases with deep-seated candidiasis showed low values or levels of lymphocyte, neutrophil, hemoglobin, hemoglobin total protein and total cholesterol.","PeriodicalId":21457,"journal":{"name":"Rinsho byori.

Bleeding time has been widely used in the diagnosis of bleeding disorders, especially thrombocytopenia, abnormalities in platelet function, vascular disorders, and von Willebrand's disease. There are a number of methods to perform the bleeding time test, but there are significant problems concerning sensitivity, specificity, and reproducibility. To study the inhibitory effects of monoclonal antibodies (anti-vWF, anti-GPIb, and anti-GPIIb/IIIa) on primary hemostasis, these antibodies were infused to normal pigs. Anti-vWF and anti-GPIb antibodies markedly prolonged the bleeding time and inhibited hemostatic plug formation. The anti-GPIIb/IIIa antibody completely inhibited ADP-and collagen-induced platelet aggregation, but no or only mild prolongation of bleeding time was observed. The quantitative bleeding time which measures both the time and the amount of blood loss is useful in the diagnosis of hemorrhagic disorders and in judging the efficacy of the treatment. It will provide important information to understand the mechanism of primary hemostasis.","PeriodicalId":21457,"journal":{"name":"Rinsho byori.

Aldolase has a molecular weight of 160 kDa and has three isozymes, namely aldolase A, B and C. The enzyme is probably present in all cells; it occurs in particularly large quantities in the muscles, liver and brain. An increase in serum aldolase is found in myotonic muscular disease, such as progressive muscular dystrophy and polymyositis. The enzyme rises in myocardial infarction, reaches a maximum within 24-48 hours and returns to normal in the course of five days. In these muscular diseases, aldolase A isozyme is elevated. Aldolase activity, especially B isozyme, in serum rises to very high levels in acute hepatitis, but is slightly elevated in cirrhosis, chronic hepatitis and obstructive jaundice. Aldolase becomes elevated in serum with malignant tumors, and isozyme A is predominant in serum. Erythrocytes are also rich in aldolase, and the enzyme rises in hemolytic anemia.","PeriodicalId":21457,"journal":{"name":"Rinsho byori.

Since telomerase activity has been detected in several human tumors and hematopoietic malignancies, this enzyme is thought to be a useful marker for cancer diagnosis. Among the components of telomerase, human telomerase catalytic subunit(hTERT) is the most important regulatory factor for telomerase activity. Therefore, quantitation of hTERT mRNA expression may be a new approach to measuring telomerase activity.","PeriodicalId":21457,"journal":{"name":"Rinsho byori.

Eighty volunteer subjects were enrolled in the study. Blood sam- ples were drawn from the fingertip of the ring finger by a single puncture and 60 μL of each sample was promptly and accurately aspirated into a blood collection chip. Then the chip was tightly sealed with chip container and was shaken to mix the contents without dispersing. For biochemical tests except of HbAlc, blood was collected without anticoagulant and centrifuged to obtain 15 μL of serum which was then diluted with 190 pL of physiological saline for the assay. For hematological tests and HbAlc, the sample was as- sayed with blood collected using EDTA-2K. As a result, a good correlation of the test values was obtained between the assay with fingertip blood and that with venous blood. The correlation coefficients were found to be 0.97 in TG, T-CHO, HDL-C, LDL-C, GLU, ALT, γ-GTP, UA, BUN and HbAlc and ≥ 0.95 for WBC, RBC, Hgb, and Hct. These results suggest that our microliter-scale blood testing can be comparable to the assay using venous blood and may be useful as a rapid and simple test for determination of basic clinical tests near the reference intervals.

However, this is not because laboratory tests are not needed in post-disaster healthcare settings, but because the implementation of triage, which prioritizes the saving of lives, is the initial aim of a Disaster Medical Assistance Team (DMAT). Disaster response ability has been reported to be exerted according to the level of experience. After the Great East Japan earthquake, by the cooperation of related societies and organizations, diagnostic reagents and instruments were supplied to 3 core university hospitals in the affected areas, contributing to building a system whereby necessary medical items could be obtained in three affected Prefectures of the Tohoku region. We should always remember that front-line medical care activities in affected areas are possible due to the backup provided by logistic support teams. The more the system for DMAT is improved, the more effective the support system will be after the super-acute phase of a disaster. [Review].</p>","PeriodicalId":21457,"journal":{"name":"Rinsho byori.

Although this constitution has changed little since the 2012 version, the contents of each part cover most of the announcements from the different medical societies concerned and are updated. The guidelines were evaluated and criticized by various users from the point of view of how this kind of resource should be.
