[Q]: Abstract: Fat cells were isolated from sedentary and exercise trained female Sprague-Dawley rats and cyclic AMP phosphodiesterase (cyclic AMP-PDE) activities were determined from crude homogenates of the fat cells in the whole homogenate, P5, P48, and S48 fractions. Exercise training resulted in a significant increase in the mean specific activity of cyclic AMP-PDE (pmol X min-1 X mg-1) from the whole homogenate and S48 fraction at cyclic AMP concentrations of 4, 8, and 16 microM and in the P48 fraction at 8 and 16 microM cyclic AMP. Cyclic AMP-PDE kinetic plots according to Lineweaver-Burk for the calculation of Michaelis constants (Km) and maximum enzyme velocities (Vmax) were nonlinear, indicating both a low and high enzyme form. The Michaelis constants were significantly lower in trained rats than those of its control for the high Km form of cyclic AMP-PDE in the whole and soluble fractions and for the low Km form of the P5 particulate fraction. The Vmax of the high Km form of the P48 particulate fraction from trained animals was also significantly higher than that found in its control. Phosphodiesterase inhibition by methylxanthines in the various fractions was similar in both trained and sedentary animals. These changes in specific activity, Michaelis constants, and Vmax of cyclic AMP-PDE from crude homogenates of isolated fat cells from exercise trained animals may account for the decreased intracellular levels of cyclic AMP following catecholamine stimulation of isolated fat cells from trained rats.

[Q]: Abstract: Thermal injuries lead to changes in both the cell-mediated and humoral responses of the patient. This study was undertaken to assess these responses in the post-burn period and also to see if bacterial infection altered these responses. It has been concluded that alterations in the cell-mediated and humoral immune responses following thermal injuries are altered by infection and consequently are also important in the healing process.

[Q]: Abstract: A prospective study of 2,209 intravenous catheters was performed in a multidisciplinary intensive care unit to determine when and why catheters were removed and which sites of insertion were associated with the least morbidity. Techniques of insertion were vigorously supervised. Central and peripheral catheters were cared for by identical protocols. Overt phlebitis or inflammation around the site was 14 times as common with peripheral catheters (353/1,024) than with centrally inserted central catheters (18/713), even though peripheral catheters were removed on the average at 2.9 days and centrally inserted central catheters at 6.2 days. Pneumothorax occurred in seven out of 713 patients with centrally inserted central catheterization, one with hemothorax and two with pneumothoraces requiring thoracostomy tubes. Five were treated successfully with simple catheter aspiration. Three patients out of 1,496 with peripheral or peripherally inserted central catheters required phlebectomy for suppurative thrombophlebitis. We concluded that overall morbidity in critically ill patients is lower from centrally inserted central catheters than peripheral intravenous catheters, with peripherally inserted central catheters in an intermediate position. Supervision of techniques of insertion has to be kept at a high level to keep complications of central catheterization at an acceptable level. Peripheral catheter sites would be better maintained with more frequent replacement of the catheter.
