We developed an in vitro method of pulsating central and microvessel pulmonary artery endothelial cells that would allow us to study the effects of increased distending pressures over a prolonged period of time. Preservation of the contact-inhibited monolayer was assessed on phase contrast microscopy and, in addition, scanning and transmission electron microscopy (SEM, TEM) were used to determine whether there were alterations in the surface characteristics or intracytoplasmic organelles that suggested cellular damage. The cells used were obtained from Rambouillet lambs, age 3-5 days, anesthetized with halothane and ventilated. The endothelium was harvested from the central pulmonary artery (CPA) by scraping the luminal surface and from the microvessels (MPA) by infusing microcarrier beads 40-140 microns external diameter. After the second passage in culture, the cells were seeded onto the translucent, flexible polyvinylchloride membrane of a transducer dome and grown to confluence. The cell dome was then connected to a blank dome with an attached quartz transducer, to a reservoir, and to stainless steel bellows tubing, all filled with culture medium and affixed to a pulsation generator. By varying the height of the reservoir, the amplitude of excursion of the bellows tubing, and the rate, the cells could be pulsated at a given distending pressure and frequency. Confluent CPA endothelial cells from three lambs and MPA cells from two others were studied after pulsation at both 100/60 and 20/10 mmHg, 60 times/min for 48 h and after nonpulsation. On phase contrast light microscopy and on SEM, the cells remained confluent.(ABSTRACT TRUNCATED AT 250 WORDS)

Objective To observe variations in the fissures, in the lobes, and in the hilar pattern of lungs and correlate these findings with clinical implications. Materials and Methods The present study was performed on random lung specimens available in the Department of Anatomy. A total of 96 lungs (47 right and 49 left) were studied for variations in the fissures and lobes, and 92 lungs (45 right and 47 left) for variations in the hilar pattern. Results Among the right-sided lungs, 70% presented incomplete horizontal fissure, 15% with absence of the horizontal fissure, and 51% with incomplete oblique fissure. Accessory fissures were also seen, but incomplete, and accounted for 17% of the total number of right lungs.Among the left-sided lungs, 62% presented incomplete oblique fissures, and 4% with absence of the oblique fissure. Accessory fissures accounted for 6% of the total number of left lungs.Regarding hilar pattern variations, 11% of the right-sided lungs showed > 2 bronchi, 69% showed > 2 pulmonary veins, and 37% showed > 1 pulmonary artery.Among the left-sided lungs, 57% showed > 1 bronchi, 21% showed > 2 pulmonary veins, and 17% showed > 1 pulmonary artery. Conclusion The field of pulmonary surgery is now highly advanced, with well-developed radiological and endoscopic techniques. Hence, a proper understanding and knowledge of these morphological variations of lung fissures and of the hilar pattern would be advantageous for surgeons, as well as for radiologists.
