The paper presents a comparative study of the contamination of a cell suspension by ions released from aluminum cuvettes (Al(3+)) and stainless steel electrodes (Fe(2+)/Fe(3+)) during cell membrane electropermeabilization by unipolar and by symmetrical bipolar rectangular electric pulses. A single pulse and a train of eight pulses were delivered to electrodes at a 2-mm distance, with 100-micros...

Sik.?I have received the enclosed letter from Mr. Hutchinson of Pusa in regard to the remarks on Electrolytic Chlorogen contained in the report of my paper on "The Selection of a Disinfectant" in the May issue of the Gazette. Whilst I am not entirely in agreement with Mr. Hutchinson in his estimation of costs based only 011 a phenol coefficient,? (Lysol, for instance, is extensively used by gyn...

SLUMMARY Both hemodynamic and electrocardiographic effects of Renografin-76 (diatrizoate meglumine) were studied in intact, anesthetized dogs. The left coronary artery in nine dogs was injected with equal amounts of Renografin-76, an equiosmolar dextrose solution (1690 mOsm/1) and a solution of the same electrolytic content (190 mEq/l sodium). Renografin and the dextrose solution produced signi...

Previous studies have shown that electrolytic lesions of the dorsal hippocampus render the instrumental performance of rats insensitive to selective degradation of the action-outcome contingency (Corbit and Balleine, 2000). In the present experiments, we sought to replicate this finding and to examine the effects of excitotoxic lesions. In the first three experiments, rats with either electroly...
