Comparison of the number, configuration, and dimensions of lodged bubbles following the capillary and feeder vessel exposure. Five rats were used for each type of exposure. Bubbles from capillary exposure are larger [L = 76mm(±23); D = 36mm(±9)] than those from feeder vessel exposure [L = 25mm(±8); D = 11mm(±5)].
* **
The results are statistically different in comparison to corresponding values (Mann-Whitney, na=59, nb=53, p<0.01, where “a” is capillary population and “b” is feeder vessel population).
