the study of the relationships of the plant species with the soil in a salty ecosystem would play a significant role in the ecologic programming and management of these inhabitants. the saline and alkaline rangelands of the golestan province are areas that contain salty soil with high underground crusts. the areas are covered by halophyte plants such as frankenia hirsuta. this species is a pere...

Three commercial membranes (NF70, NF90 and TFC-SR) were firstly characterized in terms of pure water flux and the: rejection of uncharged (alcohols and sugars) compounds. Subsequently, the rejection of monovalent (sodium and chloride) and divalent (calcium and sulphate) ions in single (NaC1, CaC12 and Na2SO4) and binary (NaC1/Na2SO4, CaClJCaSO4, NaC1/CaC12 and Na2SO4/CaSO4) salt mixtures was st...

Whether volume expansion influences NaC1 reabsorption by the diluting segment of the nephron remains a matter of controversy. In the present studies this question has been examined in normal unanesthetized dogs, undergoing maximal water diuresis. Free water clearance (CH2O/GFR) has been used as the index of NaC1 reabsorption in the diluting segment. Three expressions have been employed for "dis...

Osmotic fragility of erythrocytes was studied in ten Duchenne dystrophic patients and eight healthy controls. Lysis started in Duchenne crythrocytes at a concentration of 6.5 g/l NaC1 and in the control erythrocytes at a concentration of 5.5 gIl NaCI. At all concentrations of sodium chloride (from 6.5 g/l to 4.5 g/l) significantly greater lysis was observed in the erythrocytes of dystrophic pat...

The sodium requirements, balance, excretion, patterns and composition of some pig tissues were studied in two feeding trials and a balance trial followed by an additional feeding period with terminal tissue composition analysis. The growth of pigs fed a corn-soybean meal diet without added salt was severely restricted. Results confirm that a sodium requirement of .09% of the diet is adequate an...

an animal model was designed to study the effect of large volume hypertonic solutions (hts) for re suscitation following a hypovolemic shock. resuscitation in hypovolemic animals was performed by infusion of 15 ml/kg of normal saline (group i), 5% sodium bicarbonate (nahco3) (group ii), 5% sodium chloride (naci) and 7.5 % nahco3 1:1 vn (group iii), 5% nac1 (group iv), and 5% nacl and 5% serum a...

The adsorption of a synthetic heparinoid polyelectrolyte on poly (vinylchloride) previously treated with tridodecylmethylammonium chloride (TDMAC) was studied using radiotracer techniques to provide a more quantitative picture of antithrombogenic surface coatings. 125I-labeled polyelectrolyte was used for overall adsorption measurements. Experiments with 36Cl-labeled TDMAC yielded information o...
