osmotic

osmotic, chemical, or solvent action.

Objective:To estabilish a method of analysis for stability of Domiphen osmotic tablet(ODT),and to inviestigate its stability.

Procedures: Adopt the Kryoscopy Method for Osmotic pressure measurements to the stock solutions and its diluents;also calculate its osmotic pressure ratio to sodium chloride injection;

poikilosmotic Organisms having an internal osmotic pressure which varies, following closely that of the environment, e.g. Myxinidae.

Methods:Gatifloxacin eyedrops was prepared with benzalkonium as bacteriostat,NaCl as osmotic-pressure regulating agent and PVP as thickener:The content was determined with HPLC.

Based on erythrocytes senile model in vivo, which developed by using antibody to induce acute homolysis of RBC, the authurs studied the change of osmotic fragility oferythrocytes.

A comparative study on surface structure and osmotic fragility and microviscosity of erythrocyte membrane of aged rat and blood stagnancy model rat has been made and reportcd in this paper.
