The performance of the left ventricle was examined in a feline preparation which allowed precise control of aortic pressure, cardiac output, heart rate, and temperature. The arterial pH, Po2, and Pco2 were continuously measured with a Jewett flow-through electrode assembly. Reduction of arterial pH from 7.45 to 6.80 by HCl or lactic acid infusion was associated with a minimal reduction or no change of left ventricular contractility as measured by the stroke volume or mean ejection rate for a given left ventricular end-diastolic pressure at a constant aortic pressure and heart rate. No evidence for a diminished positive inotropic response to norepinephrine was found. Simultaneous systemic and pulmonary pressure-flow curves demonstrated that metabolic acidosis caused a reduction of systemic vascular resistance and a concurrent increase of pulmonary vascular resistance.

Micropipettes were introduced into follicles of exteriorized ovaries of rabbits anesthetized with pentobarbital. One pipette served for measurement of hydrostatic pressures, a second for the injection of small, measured amounts of saline. Impending ovulation did not measurably influence intrafollicular hydrostatic pressure. Artificial rupture could not be induced by increasing intrafollicular pressure by the injection of fluid. Tension-length diagrams for the elastic elements of the follicular wall, constructed from pressure measurements made following intrafollicular injections, indicate that a large increase in extensibility precedes rupture. Such a change in the physical characteristics of the follicle wall appears to be an essential part of the mechanism of ovulation.

Recurrent exposure of dogs to phosgene gas produces a chronic obliterative bronchiolitis with a characteristic physiologic picture. After an acute phase, in which changes in elastic behavior predominate, a definite increase in lower airway resistance is seen which persists throughout the period of exposure. Accompanying this change the uniformity of distribution of inspired air is progressively disturbed as evidenced by nitrogen washout curves. In addition, microscopic changes suggestive of early, peribronchiolar emphysema are seen.
