[EX Q]: Abstract: To study respiratory muscle interaction in patients with occlusive apnea, diaphragmatic electromyogram (EMGdi) and gastric, pleural, and transdiaphragmatic pressures (Pga, Ppl, and Pdi, respectively) were studied in seven patients during non-rapid-eye-movement (NREM) sleep. Diaphragmatic force output, as assessed by Pdi, followed the periodic changes in EMGdi but during the occlusive phase the increase in Pdi was more than the increase in EMGdi. This increase in Pdi was essentially due to an increase in Ppl, since Pga and EMGdi had a linear relationship (r = 0.98, P less than 0.001) that did not change during the occlusive and ventilatory phases. Abdominal muscle recruitment evident in Pga and abdominal motion tracings during the occlusive phase when paradoxical rib cage motion was observed suggested that this increase in diaphragmatic efficiency was likely due to a change in diaphragmatic length-tension characteristics. These results demonstrate that, in patients with occlusive apneas, the diaphragm is the predominant respiratory muscle during NREM sleep and that its function is supported by abdominal muscle recruitment.

[EX Q]: Abstract: Neutron Activation Analysis (NAA) was used to investigate trace element patterns in serum, packed cells, and dialysate of CAPD patients. The concentrations of the elements Cs, Cu, Fe, and Mn in serum and packed cells appeared to be maintained within the normal range, while the levels of the non-essential element Br in both serum and packed cells were subnormal. The serum Cr values were extremely high (20 to 50 times higher than the normal serum level). The amount of Cr absorbed from the dialysate was calculated to be ten times higher than the daily dietary uptake. The Co concentrations were normal in packed cells but were significantly increased in serum. The Rb content in packed cells was slightly lower than normal, while the serum value was normal. Se was maintained within the normal range in packed cells, but the serum concentration was slightly lower than normal. The concentrations of Zn were low in serum and appeared to be higher than normal in packed cells. In conclusion, this analysis of the trace element status of CAPD patients reveals two major abnormalities. There is an apparent loss of Br from the blood towards the dialysate and on the other hand, a dramatic accumulation of Cr into the blood as a result of the very high Cr content in the dialysate.

[EX Q]: Abstract: Adenosine infusion (100 micrograms X kg-1 X min-1) in humans stimulates ventilation but also causes abdominal and chest discomfort. To exclude the effects of symptoms and to differentiate between a central and peripheral site of action, we measured the effect of adenosine infused at a level (70-80 micrograms X kg-1 X min-1) below the threshold for symptoms. Resting ventilation (VE) and progressive ventilatory responses to isocapnic hypoxia and hyperoxic hypercapnia were measured in six normal men. Compared with a control saline infusion given single blind on the same day, adenosine stimulated VE [mean increase: 1.3 +/- 0.8 (SD) l/min; P less than 0.02], lowered resting end-tidal PCO2 (PETCO2) (mean fall: -3.9 +/- 0.9 Torr), and increased heart rate (mean increase: 16.1 +/- 8.1 beats/min) without changing systemic blood pressure. Adenosine increased the hypoxic ventilatory response (control: -0.68 +/- 0.4 l X min-1 X %SaO2-1, where %SaO2 is percent of arterial O2 saturation; adenosine: -2.40 +/- 1.2 l X min-1 X %SaO2-1; P less than 0.01) measured at a mean PETCO2 of 38.3 +/- 0.6 Torr but did not alter the hypercapnic response. This differential effect suggests that adenosine may stimulate ventilation by a peripheral rather than a central action and therefore may be involved in the mechanism of peripheral chemoreception.
