THE solutions of fibrinogen, thrombin and sodium chloride employed in these experiments contained about 0 5 % of tri-sodium citrate. As source of fibrinogen human plasma was ordinarily used, being prepared by mixing 12 cc. of blood, immediately after withdrawal from a vein of the forearm, with 1 cc. of 0-85 % sodium chloride solution to which 013 g. sodium citrate had been added. After centrifu...

1. DNA has been isolated from different mammalian tissues. The DNA preparations were free from RNA, protein and polysaccharides and have a similar range of sedimentation coefficients (approx. 24s). 2. Protein was removed by a two-stage extraction with a phenol-cresol mixture by using a detergent with 4-aminosalicylate in the first stage and sodium chloride in the second. 3. Polysaccharides rema...

introduction: pomegranate (punica granatum l.) belong to punicaceae family is native to iran and grown extensively in arid and semi-arid regions worldwide. pomegranate is also important in human medicine and its components have a wide range of clinical applications. cracking causes a major fruit loss, which is a serious commercial loss to farmers. fruit cracking, seems to be a problem that less...

expansive soils are considered a worldwide problem as they cause extensive damage tocivil engineering structures. an important characteristic of expansive soils is theirsusceptibility to volume change due to the phenomenon of wetting and drying. this paperpresets the effect of pore water quality on the swelling and shrinkage behavior of anexpansive soil during wetting and drying cycles. thirty ...

to evaluate germination and seedling growth of safflower an experiment carried out as factorial with two factor; temperature (5, 15, and 25 °c) and salinity of sodium chloride (0, 5, 10, and 15 ds/m) based on randomized complete block design with four replications, in dept. of horticulture of urmia university. results of different concentration sodium chloride on germination and seedling growth...

Staphylococcus aureus organisms, grown in basal medium of water activity (a,) 0.993 and in basal medium adjusted to several different a, values by addition of NaCl, were analysed for the following components: sodium, potassium, calcium, magnesium, total amino acids, inorganic phosphate, chloride, water, DNA, RNA, protein. Cell water decreased from 1-66 to 0.83 g./g. dry weight when a, was decre...
