[Comparison of two osmometers at the clinical chemistry laboratory].

Evaluation of the "Auto-Stat 6010" automatic osmometer and its comparison with the "digimatic-advanced 3DII" manual osmometer.

The results are presented of a comparative study between two osmometers, a manual one, Digimatic-Advanced 3DII (Advanced Instruments, Medical Europa, Barcelona), and an automatic one, Auto-Stat 6010 (Kyoto, Daiichi, Kagaku, Menarini, Firenze). Both osmometers have the same operation principle, but they employ different systems for determination of the freezing point depression. Both instruments...

Randomized comparison of in vivo performance of two point-of-care tear film osmometers

PURPOSE To compare the in vivo precision of two commercially available point-of-care osmometers among normal subjects with no dry eye disease. METHODS Twenty healthy adults with healthy ocular surfaces were evaluated by licensed eye care practitioners. All subjects had low Ocular Surface Disease Index score (<5), normal tear breakup time (>10 seconds), and no evidence of corneal fluorescein s...

A Comparison of Fundamental Performance between Two Bench Top Clinical Chemistry Analyzers

Comparison of kinetic study and protective effects of biological dipeptide and two porphyrin derivatives against metal cytotoxicity in human lymphocytes

In this research, dipeptide (his-β-alanine) and porphyrin derivatives were choosen for comparing chelating ability of toxic metals such as Al3+, Cu2+, Hg2+ and Pb2+ in vitro. The reason for choosing these two compounds is that both of them are naturally present in biological systems and comparison of chelating ability of these two compounds has not yet been done. Synthesis and comparison of kin...
