A new isothermal titration calorimeter has been designed to facilitate the study of heats of reaction and heats of solution at constant temperature. With this calorimeter, endothermic or exothermic processes can be studied at temperatures constant to ±0.0002°C. Heat effects are compensated by balancing the heat effect of the process taking place in the calorimeter against a variable heat and a constant cooling Peltier device. The calorimeter was tested by measuring the heat of ionization of water and the heat of dilution of aqueous HClO_4 solutions. For these systems heats were measured to an accuracy of ±0.02 calorie. Log K, ΔH°, ΔS° and ΔCp° values valid at zero ionic strength have been reported for the interaction of CN^- with Ni^2+ , Zn^2+ , Cd^2+ and Hg^2+ in aqueous solution at 10, 25 and 40°C. The results were compared to electrostatic predictions and it was found that electrostatic considerations do not predict the metal-ligand behavior in solution. The effect of temperature upon the behavior of ΔG, ΔH and ΔS is predicted using the ΔCp values determined in this study. Log K, ΔH°, ΔS° and ΔCp° values were determined for the glycinate complexes of bivalent Mn, Fe, Co, Ni, Cu, Zn and Cd. The results indicate that solvent effects for the various metal complexes are similar (based on ΔCp values) and that the temperature dependence of the thermodynamics of the metal glycinate complexes are similar for each of the metal glycinate systems.

Estudos introduziram um novo método para avaliação da pré-carga, baseados na análise da variação da pressão sistólica (VPS) durante a ventilação mecânica. O presente estudo tem por objetivo avaliar se a VPS e sua derivada delta down (ddown) são indicadoras precoces de hipovolemia e guias de reposição volêmica com solução hiperosmótica e hiperoncótica no cão anestesiado submetido a hipovolemia. Doze cães sem raça definida, anestesiados com propofol, fentanil, rocurônio e isoflurano, e esplenectomizados, foram submetidos a sangramentos parciais de 5% da volemia até se atingir a retirada total de 20% da volemia (14 ml.kg-1). Após cada momento foram realizadas análises hemodinâmicas, respiratórias e sangüíneas. Em seguida, os cães foram submetidos à reposição volêmica com solução de NaCl a 7,5% em dextran 70 a 3,75% (4 ml.kg-1) em 10 minutos e novas análises foram realizadas aos 5 e 30 minutos após a reposição volêmica. A freqüência cardíaca não apresentou alteração... / The insidious hypovolemia detection in the intraoperative is difficult due to little specificity of clinical and hemodynamic signs. Studies introduced a new method for preload evaluation, based on systolic pressure variation analysis (SPV) during mechanical ventilation. The present study aims to evaluate if SPV and its derived delta down (ddown) are early indicator of hypovolemia, and guides of volemic replacement with hyperosmotic and hyperoncotic solution in anesthetized dogs submitted to hypovolemia. Twelve mogrel dogs, anesthetized with propofol, fentanyl, rocuronium and isoflurane, were submitted to graded haemorrhage of 5% of its volemia to reach the total of 20% of volemia (14 ml.kg-1). After every haemorrhage period, hemodynamic, ventilatory and blood atributes were studied. Imediately after, the dogs were submitted to volemic replacement with 7.5% NaCl solution in 3,75% dextran 70 (4 ml.kg-1) in 10 minutes, and the atributes were studied after 5 and 30 minutes following the volemic replacement. Heart rate was not changed significantly. Mean arterial pressure decreased significantly during haemorrhage, and increased... (Complete abstract, click electronic access below)
