STIMULATION OF CHLORIDE TRANSPORT IN CHARA BY EXTERNAL PH CHANGES

Determination of Solute Permeability in Chara Internodes by a Turgor Minimum Method : Effects of External pH.

The analysis of Sha'afi et al. (Sha'afi, Rich, Mickulecky, Solomon 1970 J Gen Physiol 55: 427-450) for determining solute permeability in red blood cells has been modified and applied to turgid plant cells. Following the addition of permeating solute to the external medium, a biphasic response of cell turgor can be measured with the pressure probe in isolated internodes of Chara corallina. Afte...

Modification by timolol of catecholamine stimulation of chloride transport in isolated corneas.

In the isolated frog cornea, 10(-5)M timolol completely blocked the stimulation of chloride transport by 10(-6)M isoproterenol. In this preraration, timolol inconsistently modified the response to epinephrine. In some experiments, epinephrine added to the bathing medium after timolol caused a smaller than normal increase in chloride transport, but in other instances, epinephrine caused a decrea...

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Regulation of solute transport in streptococci by external and internal pH values.

Sodium Chloride Transport by Rabbit

The results of the present study indicate that NaC1 transport by in vitro rabbit gallbladder must be a consequence of a neutral coupled carriermediated mechanism that ultimately results in the active absorption of both ions; pure electrical coupling between the movements of Na and C1 can be excluded on the grounds of electrophysiologic considerations. Studies on the unidirectional influxes of N...
