Effect of Two Recently Synthesized Pheno-Thiazine Derivatives Upon Experimental Cardiac Arrhythmias

Potassium-Selective Membrane Sensor Based on Two Recently Synthesized Poly(oxyethylene) Derivatives

Two poly(oxyethylene) derivatives 1.10-bis(2'-benzoic acid)-1,4,7,1-tetradecane (L1) and 1,7-bis(2'-benzoic acid)-1,4,7-trioxaheptane (L2) were used as suitable ionophores for the preparation of potassium-selective PVC-membrane electrodes. The resulting electrodes based on L1 and L2 exhibit linear responses to the activity of K+ ions within the concentration ranges of 3.1<em...

Cardiac arrhythmias in experimental syncope.

Oxytocic effect of lignocaine and its recently synthesized analogues.

Local anaesthetics as a group possess spasmolytic effect on the smooth muscles (2). Uterine muscle though basically a smooth muscle organ, differs from other smooth muscle organs in many respects. Physiologically it is more under the control of sex hormones than the autonomic nervous system. There exists wide species variation in the responses to autonomic nervous stimulation. Pharmacologically...

Cardiac arrhythmias in experimental subarachnoid hemorrhage.

Experimental subarachnoid hemorrhage (SAH) in dogs was produced by introducing blood into the subarachnoid space through a catheter connected to an artery of the animal. The intact animals and those with preserved vagi and heart sympathetic innervation, developed arrhythmias with short latencies which correlated with the sudden increase in the intracranial pressure. The animals with sections of...
