Further studies on perfusion of isolated frog's heart with modified Ringer solutions (glucose-Ringer, maltose-Ringer and lactose-Ringer).

چکیده
The present series of experiments have served to elucidate unequivocally that the performance of isolated frog's heart improves considerably on reduction of sodium chloride to 60 mM/L in the perfusate, and that probably this improvement is not affected by the presence of disaccharides and glucose added to the perfusate so as to maintain isotonicity, although further work is required to corroborate the latter.

Effect of guar gum on glucose and water absorption from isolated loops of jejunum in conscious growing pigs.
Four pigs initially of 30 kg live weight were surgically prepared with two re-entrant cannulas in the jejunum 1.0 m apart which allowed an isolated loop to be formed through which solutions were perfused. 51Cr-EDTA was used as a marker for measuring net secretion or absorption. A new Ringer solution was made, the ionic content of which resembled more closely that found in the jejunum of pigs gi...

Background & Aims: Metabolic acidosis can be harmful and can complicate cardiopulmonary bypass (CPB) during coronary artery bypass graft surgery. We hypothesized that the pump prime can cause this disturbance. We compared effects of Ringer solution with Ringer Lactate, two types of priming fluid in producing metabolic acidosis in patients undergoing coronary artery bypass graft (CABG) ...Materi...
متن کاملRinger Acetate versus Ringer Lactate Cardioplegia: A comparative study in Mitral Valve Surgery
Background: Ringer lactate has long been used in many surgical procedures as one of the isotonic solutions. However, with the development of Ringer acetate, it becomes the crystalloid of choice owing to its main metabolism in muscles unlike lactate which is mainly in liver, also it corrects acidosis more rapidly than lactate and it needs less 02 and produces less CO2. Ringer acetate has also a ...
متن کاملOn Histamine - Receptor Interaction
The effects of external divalent cations on drug-receptor interaction were examined using guinea pig taenia. The effects of histamine on membrane potential of taenia in various solutions were also examined using the sucrose gap method. Ca2+ and Me2+ played an important role in the combination of histamine with its receptor. Sr2+, Mn2+ and Co2+ do not substitute for. Ca2+ and Me2+ in this intera...
