The blebs appear to trigger an immune overreaction.
In more than 70 DPNBs using this technique, including the peno-scrotal bleb, bilateral spread of local anaesthetic has in all cases provided a successful block, with no patients requiring additional analgesia prior to hospital discharge.
1) In some cases, the growing nodules can cause a ball valve effect, with subsequent overdistension of alveoli, leading to release of air into interstitial tissue and eventual rupture of a subpleural bleb.
Other cellular vesicles include argosomes, blebs, and apoptotic bodies.
Development and bursting of these blebs are linked to a higher transpulmonary pressure (alveolar pressure minus pleural pressure) in the apex of the thorax.
Using the energy gained from being in close contact with bacteria (and using bacterial-derived lipids), cells were able to get bigger and expand the size of their blebs.
In 1971 AMAX drilling intersected mineralisation widespread below about 122m, but of low grade, occurring as disseminations, veins, blebs and narrow massive bands of pyrite, pyrrhotite, sphalerite, chalcopyrite, galena, quartz and calcite in metasediments.
On gross examination, 4 of the resected lung specimens (36%) had recognizable blebs or bullae.
Gold and silver mineralization occurs in the hanging and footwall as native metal and associated with disseminations, blebs and fracture fillings of arsenopyrite, pyrite.
For example, drainage blebs, naturally, have prominent placement in the globe and so consideration of the position is important, especially to avoid diplopia (hence high positions, shielded under the lid are the most ideal).
Mineralization styles observed in the core includes both syngenetic (bedding parallel and disseminated fine pyrite lenses and blebs replaced by chalcopyrite and carrolite) and epigenetic (fracture and vein hosted sulphides).
