Eggs and early embryonic stages of the sea urchin Lytechinus pictus were subjected to hyperbaric gas pressures and rapid decompression. All stages showed a remarkable tolerance to gas supersaturations. No damage or internal bubbles were apparent in t

The bubble formation properties of various porous surfaces at low gas supersaturations were investigated. Polystyrene and silica particles with pore sizes ranging from 40 to 1000 A were used as representative surfaces for this study. Among the polyst

It has frequently been assumed that hydrophobic surfaces serve as initiation points for in vivo bubble formation; yet, no studies have demonstrated that this relationship actually exists. In the present investigation, the concept of spontaneous bubbl

Macrophages and other cells are capable of ingesting a variety of solids from their external environment. When such phagocytic processes occur in animals, they can lead to phagocytosis from the respiratory or the digestive tract of particles containi

1. 1. Young specimens of trout, catfish, sculpin and salamanders were equilibrated with elevated gas pressures, then rapidly decompressed to ambient pressure. 2. 2. The newly hatched forms tolerated extremely high gas supersaturations; equilibration

The high dissolved gas tensions required for the secretion of gases into deep-sea fish swimbladders are thought to be produced in the rete mirabile by a countercurrent multiplication mechanism, the capacity of which is theoretically limited by the ph

A miniature cuvette pressure chamber for microscopy and highspeed (400 frames per second) cinephotographic recordings was developed to study intracellular bubble formation in Tetrahymena. The investigations show, for the first time, that intracellula

The concentrations of myoglobin from breast muscle of three post-hatch developmental stages of Ad61ie penguins and of adult Chinstrap and Gentoo penguins are reported, and some biochemical and oxygen-binding characteristics of these are given. 2. The
