We investigated the influence of head-dependent positions upon functional residual capacity (FRC) and arterial oxygen saturation in 25 patients with clinically stable chronic air-flow obstruction and 25 normal subjects. Lung volume was measured by gas dilution in normal subjects and by plethysmography in patients with chronic obstructive pulmonary disease(More)
In 8 Holstein cows, 50 colony-forming units (CFU) of Escherichia coli was administered into 1 mammary gland. Infections were established in all inoculated glands. In 4 of the 8 cows, 500 mg of gentamicin sulfate was administered by intramammary infusion 14 hours after inoculation; the other 4 cows were untreated controls. Infusions of gentamicin also were(More)
To assess the effects of azathioprine withdrawal, renal recipients with grafts > 2 yr function (103 study patients) were tapered off azathioprine over a 1-yr period and compared to 69 patients 2 yr after transplant who were not tapered (controls). Of the 103 study patients, 16 (15%) were living-donor transplants and 87 were cadaveric. Of the 69 control(More)
