abstract background: regarding the diagnostic errors of the classic criteria including serum ascites albumin gradient (saag), total protein concentration and the adapted light et al’s criteria in distinguishing transudate versus exudates, we evaluated the ascitic fluid to serum bilirubin ratio as a new criteria in this regard. we also evaluated whether the combination of bilirubin ratio with ea...

Idiopathic polyarthritis (IPA) is a very common inflammatory arthropathy in the dog. Canine IPA is diagnosed mainly by detecting increased number of leukocytes in the synovial fluid (SF), which is easily influenced by glucocorticoid therapy. We obtained 31 SF samples from 24 IPA dogs prior to (n=19) and/or after (n=12) 1 to 10 weeks of glucocorticoid therapy. The SF total protein concentrations...

Evaluation of dairy replacement calf health is generally divided into the pre-weaning and post-weaning periods; with an average weaning age of 8.6 weeks [1]. In 2007, the NAHMS Dairy study found that the pre-weaning period accounts for about 81% of total dairy replacement calf mortality [1]. Accordingly, management strategies to optimize health during this period will have the greatest impact o...

Seed protein usually is not sensitive to environmental fluctuations; its banding pattern is very stable which advocated for cultivars identification purpose in crop. This study was planned to study effect of water deficit on protein content and protein banding pattern of wheat genotypes. In this study five wheat genotypes were planted in early November, growing season of 2008-2009. The experime...

While current data indicate only free (unbound) drug is pharmacologically active and is most predictive of response, pharmacodynamic studies of vancomycin have been limited to measurement of total concentrations. The protein binding of vancomycin is thought to be approximately 50%, but considerable variability surrounds this estimate. The present study sought to determine the extent of vancomyc...

A 60-year-old woman, free of other disease, with severe clinical hyperthyroidism had normal total serum T4 with elevated free T4 concentration and T3 resin uptake characteristic of hyperthyroidism, with thyroid binding globulin (TBG) deficiency. However, serum TBG concentration as determined by immunoassay was normal, suggesting that the biochemical defect affecting the T4 binding sites did not...

E xamination of cerebrospinal fluid (CSF) total protein is used chiefly to detect increased permeabili ty of the blood-brain barrier to plasma proteins or increased intrathecal secretion of immunoglobulins (1). A rapid and quite precise method is required. The biuret method is considered as a potential reference method for total protein determination in biological fluids (2-4). It has been modi...
