An ultraviolet germicidal chamber has been developed, which disinfects the spike and the solution-bag outlet before spike insertion. This report summarizes the results of a multicenter trial carried out to determine if this device reduces the incidence of peritonitis in patients on CAPD. Ten centers contributed 167 patients who were followed during a base-line historical control period for a minimum of four months. Thereafter, 93 patients were randomized to a control group, and 74 to the test group. After an interim period for retraining (both groups) and change over (test group), a trial period of nine months was undertaken. Peritonitis rates and actuarial analyses of time-to-peritonitis showed no significant differences between historical and trial periods in either group, or between groups during either period. In both groups, rates of pe...

With this technique the catheter distal (external) segment was Implanted in a subcutaneous tunnel for 4–6 weeks. Therefore, no irrigation of exposure to dialysate was present. Secondary exteriorization and irrigation (CAPO exchanges) demonstrated no episodes of primary catheter obstruction. Fifteen mongrel female dogs had 30 catheters implanted; 2 catheters simultaneously in each dog. One catheter was implanted with the interabdominal segments in the pelvis and the second interabdominal segment directed upward In direct contact with the omentum. Following initial irrigation, all catheters were patent, but within 24–48 hours all upwardly directed catheters were obstructed. Nine of the 15 downwardly directed catheters became obstructed by omentum wrapping around the catheter within 5 days. Preliminary studies have failed to demons...

The authors applied ultrasound to enhance the rate of peritoneal mass transfer. in m'tro permeation experiments were performed with the parieta1 peritoneum taken from a rabbit. A small piece of the peritoneum had been set between the donor and receptor compartments of a membrane permeation system, which was comp]etely submerged in a water bath of an ultrasonic cleaner. Experiments were performed with or without application of ultrasound, Average rates of enhancement were 160 and 150O,6 for creatinine by application of ultrasound of 28 and 45 kHz. respectively These findings implied that the application of ultrasound should directly change the permeability of the parieta1 peritoneum. bi vivo experiments were also perforTned with rabbits plaeed in a water bath of a large ultrasonic cleaner under anesthesia. Rates of peritoneal transport in vivo for urea and creatinine were also enhanced to 159, 113, and 830,'u for urea and were 149, 112, and 949'G for creatinine {n=3) on the average with application of ultrasound of 28, 45, and 1 oo kHz, respectively No signlficant change in ultrafi1tration, however, was found between the results with ultrasound and those without ultrasound, which may suggest that the ultrasound possibly increase the local blood fiow rate that could increase the net ultrafi1tration.

La tesis central de las teorias esteticas modernas plantea que lo artistico se da esencialmente en la obra de arte y que estas son autonomas. En sintesis, que hay contenidos y expresiones en el libre albedrio de lo interpretativo y lo perceptivo. ?Bajo que condiciones, bajo que funcion y perspectiva podrian disenarse nuevos curriculos para la ensenanza de las artes? ?Por la reproduccion de las actitudes consagradas como esteticas por el sistema educativo y la formacion del gusto?
