(16) Vascular changes included perivascular deposits of proteinaceous material presumably from leakage of serum proteins, variable electron lucency of endothelial cell cytoplasm, an apparent increase in pinocytotic vesicles, rare platelet thrombosis of capillaries, and rare intravascular blebs of luminal plasma membrane.
(17) Formation of blebs was dose dependent and preceded release of LDH and trypan blue uptake.
(18) In addition, CHO cells displayed membrane bleb formations similar to those found in CHO cells after exposure to established inhibitors of protein synthesis, puromycin and anisomycin.

Definition:
(n.) A bleb; a vesicle, or an elevation of the cuticle, containing a transparent watery fluid.
(n.) The ovoid prominence below the opening of the ear in the skulls of many animals; as, the tympanic or auditory bulla.
(n.) A leaden seal for a document; esp. the round leaden seal attached to the papal bulls, which has on one side a representation of St. Peter and St. Paul, and on the other the name of the pope who uses it.
(n.) A genus of marine shells. See Bubble shell.
Example Sentences:
(1) A hallmark of C. septicum infection is the absence of acute inflammatory cells in involved tissues or in bulla fluid.
(2) These criteria were typed as A through D starting with nuclear homogenization and passing through vesicle formation, bulla formation and finally ulceration.
(3) We recommend this skin incision for young patients with pneumothorax if the chest CT scan confirms that the bullae or blebs are localized to the apex of superior segment of the lower lobe.
(4) To test ciliary clearance, the fluid was placed in either the tympanum or the mastoid bulla.
