Involvement of ultrasonically induced cavitation in the production of hind limb paralysis of the mouse neonate.
The exposure conditions which produce hind limb paralysis in 10%, 50%, and 90% of mouse neonate specimens exposed to 1-MHz ultrasound at 10 ø C and at 1and 16-atm hydrostatic pressure were determined for the intensity range 86-289 W/cm 2. The change in the exposure duration for 50% of the specimens paralyzed resulting from pressurization to 16 atm was negligible at 86 and 144 W/em 2 but was alm...
متن کاملCavitation pressure in water.
We investigate the limiting mechanical tension (negative pressure) that liquid water can sustain before cavitation occurs. The temperature dependence of this quantity is of special interest for water, where it can be used as a probe of a postulated anomaly of its equation of state. After a brief review of previous experiments on cavitation, we describe our method which consists in focusing a hi...
متن کاملCavitation in water: a review
Liquid water can be brought beyond the liquid–vapor equilibrium line into a metastable state, before nucleation of bubbles (cavitation) occurs. We review the experimental work on cavitation in water, focusing on the determination of the ultimate degree of metastability at which liquid water can exist. We also present practical applications of metastability and cavitation. To cite this article: ...
متن کاملComparison of bronchial responsiveness to ultrasonically nebulized distilled water (UNDW), methacholine, and ultrasonically nebulized distilled cold water (UDCW) in patients with sulfur mustard gas-induced asthma
OBJECTIVE To evaluate bronchial challenges using three different stimuli as screening tools for bronchial hyper-responsiveness in sulfur mustard gas-induced asthma. DESIGN Randomized, cross-over clinical study. SETTING University hospital. PATIENTS Eighteen veterans with mustard gas-induced asthma and 18 normal veterans as the control group. INTERVENTION Pulmonary function tests and inh...
متن کاملUltrasonically induced temperature elevation in mouse ovary.
Temperature increases, resulting from exposure to 1 MHz ultrasound, were measured in in situ and in exteriorized mouse ovaries. It is concluded that temperature increases from exposure to 10 W/cm2 and less are probably not significant for producing ovarian tissue damage, but that 25 W/cm2 exposures, and greater, are of such magnitude that damaging thermal levels ensue. The significance of blood...
