2144 CLINICAL CHEMISTRY, Vol.35,No.10,1989 We conclude that the influence of dextran on protein determinationiseasily avoided by adding glycerol to the blank reagent. The influence of Hemaccel was studied by dissolving control sera in a 35 g/L solution of this interfering compound. Results for total protein were found to be too high, but adding glycerol to the blank reagent did not result in a ...

S EVERAL DIFFERENT TYPES of commercially available control specimens (Chemonitor,* Enzatrol,* and Versatol, A, A Alt., E, and E-Nt) are employed by many laboratories for quality control purposes. These control specimens may be submitted each day for each determination performed in the laboratory. Unless the concentrations of these control specimens are made to vary in some unpredictable fashion...

Purpose. The gravimetric method of weighing surgical sponges is used to quantify intraoperative blood loss. The dry mass minus the wet mass of the gauze equals the volume of blood lost. This method assumes that the density of blood is equivalent to water (1 gm/mL). This study's purpose was to validate the assumption that the density of blood is equivalent to water and to correlate density with ...

The decolorization of molasses by 17 different fungi in 2 media was studied. Trichoderma viride showed the highest decolorization yield (53.5%) when cultivated at 30ºC for 7 days in Medium 1 which contained the molasses which was diluted to 40 g/L in distilled water. The other Trichoderma species and Penicillium sp. also gave similar results of 40-45%. Decolorization yield was increased by addi...

In this article design and operation of a parallel-plate capacitive sensor based on the dielectric capacitance and conductance change of the gap medium is reported. The designed system was used to determine characteristics of different water liquids as a result of the capacitance variations. The air gap capacitance is measured and then by filling the gap with a liquid the capacitance is monitor...

distilled water. The medium was prepared by placing 40 to 50 sterile rice grains in each sterile petri dish containing 25 ml of sterile distilled water. After hydration the rice grains became submerged beneath a thin layer of water, which discouraged the growth of molds. Twenty samples of soil from various sources were tested by this method. The results of a few of these are shown in table 1. S...

The studies employed the cholesterol-fed rabbit model of Alzheimer's disease (AD) to investigate the relationship between AD-like neurofibrillary tangle (NFT) neuropathology and tau protein levels as the main component of NFT. We measured brain and plasma tau levels and semiquantified NFT-like neuropathology in cholesterol-fed rabbits administered drinking water of varying quality (distilled, t...

an almost moribund condition, I used intravenous injections of quinine bihydrochloride grs. 10 in 10 c.c. of normal saline with 10 minims of adrenalin chloride solution added. The injections were given very slowly at the rate of 1 c.c. per minute. In several other cases associated with collapse I used pituitrin 1 c.c. in 5 c.c. of normal saline, given slowly at the rate of about 2 c.c. per minu...

The efficacy of using calcium carbonate as an osmolar control treatment for acid-base studies in horses receiving alkalizing compounds was evaluated. Six mares were nasogastrically intubated with isomolar quantities of sodium or calcium as sodium bicarbonate or calcium carbonate or with water during three treatment periods. Doses of the carbonic acid salts were 500 mg/kg sodium bicarbonate mixe...
