Ultramicro- and micro-determination of chloride by argentimetric titration with the indicator dichlorofluorescein.

A reliable ultramicro modification of the Franco and Klein (1) determination for chloride, using 20 pi. of plasma, is described. A second procedure, requiring 0.2 ml. of plasma and substituting a titrating syringe for a buret, is suggested as a fast and adequate substitute in the absence of either extensive laboratory facilities or trained personnel. Data on reproducibility and recovery, and a ...

Stabilized with Methylene Blue

The in vitro viability, chemotaxis, and labeling stability of leukocytes labeled using 99mTc-exametazime stabilized with methylene blue were evaluated and compared with those obtained using nonstabilized 99mTc-exametazime. Methods: Two identical leukocyte populations, from 30 healthy donors, were labeled simultaneously using freshly prepared and 2-h-old stabilized 99mTc-exametazime. The followi...

Adsorption of Methylene Blue from Aqueous Solutions by Silk Cocoon ‎

This study concerns the performance of cocoons spun by silk worms as a natural ‎adsorbent for removal of Methylene Blue (MB) from aqueous solutions. To study the adsorption ‎process, the effect of various parameters such as contact time, adsorbent dosage, dye initial ‎concentration, and pH of the solution were investigated. According to the experiments, the kinetic ‎data were best described by ...
