Measurement of plasma hemoglobin is useful in variety of clinical conditions. In the present study we have developed a kinetic
method to estimate plasma haemoglobin by using o-tolidine. This method is sensitive, rapid, economical, simple and less influenced
by interfering substances. It measures plasma haemoglobin in the range of 6 to 400 mg/L (normal range < 50 mg/L) in less than
two minutes and can be easily automated. 相似文献

Introduction
We aimed to determine the number of repeated cholesterol (RC) tests and the ratio of unnecessary-repeated cholesterol (URC) tests among patients admitted to Pamukkale University Hospital (Denizli, Turkey) and provide solutions to avoid URC testing.Materials and methods
Total cholesterol (T-cholesterol) tests (N = 86,817) between June 2014 and May 2015 were evaluated. The tests performed more than once per patient were determined as RC test (N = 28,811). RC test with an interval shorter than 4 weeks were determined as URC test (N = 3968) according to the shortest retest interval stated in ACC/AHA blood cholesterol guideline. RC testing included internal medicine, surgery and paediatric outpatients and inpatients. Reference change value (RCV) of total cholesterol was calculated.Results
The 33.1% of the T-cholesterol tests were RC tests (N = 28,811), 13.7% of them were URC tests (N = 3968). Our RCV value was 25%. The percentage change between consecutive tests was less than RCV in 86.1% (N = 3418) of URC tests. URC tests were performed more frequently in patients with desirable total cholesterol value (P < 0.001).Conclusion
There is a significant part of repeated T-cholesterol tests requested in our hospital. URC test requests can be evaluated by laboratories and the obtained data should be shared with clinicians. Laboratories can calculate RCV for the tests they performed and report this value with the test result. To prevent from URC tests, a warning plug-in can be added to hospital information software in accordance with guidelines to prevent from URC test requests.Key words: unnecessary repeated cholesterol test, cholesterol retest interval, reference change value, laboratory costs, preanalytical phase, test requesting 相似文献4.
Prior studies of open innovation have highlighted the effects of different flows of knowledge between firms and external partners—such as flows of software code, technical solutions, or new product ideas—and how firms face a “paradox of openness” about how open to be to external sources while also appropriating value. There are increasingly flows of more provisional knowledge as well, in the form of product innovation rumors exchanged within online technology blogs. Our study objective was to understand how product innovation rumors are used by firms as both inflows and outflows of provisional knowledge and their effect on the innovation process. Using interview data within a high-technology firm whose forthcoming products were the subject of rumor within technology blogs, we develop propositions regarding how inflows of product innovation rumors affect innovation decisions (while addressing concerns about appropriability and intrafirm knowledge flows) and how outflows from firms may affect stakeholders outside the firm (through selective revealing and influence of technology blog editors). Product innovation rumors in part address the paradox of openness by forming an informal means of open innovation alongside formal processes, and we suggest further research opportunities in this domain. 相似文献

A female patient who had two primary cancers was investigated. Biochemical analysis of patient's serum for different parameters
indicated an alteration in the metabolic process. Prognostically, the patient has shown favourable clinical features. 相似文献
