We used an automated four-wavelength spectrometer to measure the concentration of total hemoglobin, percent oxyhemoglobin, carboxyhemoglobin, and methemoglobin, and concentration of oxygen bound to hemoglobin in the blood of humans, dogs, and baboons under clinical and various experimental conditions. Measurements of total hemoglobin and methemoglobin with this simple method were comparable to ...

Hypertonic saline solution can absorb part of the intracellular fluid volume into the extracellular space. The effects of this solution on the cardiovascular system are increased coronary flow and increased left ventricular contraction, without sympathetic system activation. This study was designed to assess the effects of hypertonic saline solution in open heart surgery and to compare it w...

Alcohol oxidation is an important reaction in organic syntheses. Some of these reactions must beunder difficult conditions in respect of high temperature and pressure. In many cases, reactions areconducted by environmentally in appropriate solutions. In this study, preparing an effectivenanocatalyst and estimating the optimum provisions of its production processes are assessed. Twomajor and cru...
