Haemolytic effects of hypo-osmotic salt solutions on human erythrocytes.

Studies of Human HbAA Erythrocyte Osmotic Fragility Index of Non-Malarious Blood in the Presence of Five Anti-malarial Drugs

Background: The capacity of human HbAA erythrocytes of non-malarious blood to withstand osmotic stress in the presence of five antimalarial drugs, Chloroquine phosphate, Quinine, FansidarTM, CoartemTM and HalfanTM was studied in vitro. Materials and Methods: Aqueous solutions of four increasing concentrations of the drugs used in this investigation were in the order: 0.2%, 0.4%, 0.6% and 0.8% (...

Effects of osmotic shock on production of β-carotene and glycerol in a naturally isolated strain of Dunaliella salina

Article history: Received on: 21/05/2016 Revised on: 23/06/2016 Accepted on: 14/07/2016 Available online: 30/08/2016 In the present study, the effects of hypo-osmotic and hyper-osmotic shock on β-carotene and glycerol production by a native strain of Dunaliella salina isolated from Maharlu Salt Lake, Fars province, Iran, were investigated. The amount of β-carotene and glycerol at 1 h, 2 h, 8 h ...

An Evaluation of Four Electrolyte Models for the Prediction of Thermodynamic Properties of Aqueous Electrolyte Solutions

In this work, the performance of four electrolyte models for prediction the osmotic and activity coefficients of different aqueous salt solutions at 298 K, atmospheric pressure and in a wide range of concentrations are evaluated. In two of these models, (electrolyte Non-Random Two-Liquid e-NRTL and Mean Spherical Approximation-Non-Random Two-Liquid MSA-NRTL), association between ions of opposit...

Evaluating the Functional Status of Spermatozoa in Smokers Using Hypo-osmotic Swelling Test

Effects of strongly anisosmotic and NaC1 deficient solutions on muscimol- and glutamate evoked whole-cell currents in freshly dissociated hippocampal neurons

Sudden exposure of dissociated hippocampal neurons to strongly hypoor hyperosmotic solutions suppresses voltage gated Na +, K + and Ca 2+ currents. We investigated whether ligand gated ion currents were similarly shut down by exposure to anisosmotic solutions. The effect of hypo-osmotic, NaCI deficient (mannitol-substituted), or hyper-osmotic test solutions delivered from a flow pipette was tes...
