[Q]: Abstract: Pulmonary lymph drains into the thoracic duct and then into the systemic venous circulation. Since systemic venous pressure (SVP) must be overcome before pulmonary lymph can flow, variations in SVP may affect lymph flow rate and therefore the rate of fluid accumulation within the lung. The importance of this issue is evident when one considers the variety of clinical interventions that increase SVP and promote pulmonary edema formation, such as volume infusion, positive-pressure ventilation, and various vasoactive drug therapies. We recorded pulmonary arterial pressure (PAP), left atrial pressure (LAP), and SVP in chronic unanesthetized sheep. Occlusion balloons were placed in the left atrium and superior vena cava to control their respective pressures. The superior vena caval occluder was placed above the azygos vein so that bronchial venous pressure would not be elevated when the balloon was inflated. Three-hour experiments were carried out at various LAP levels with and without SVP being elevated to 20 mmHg. The amount of fluid present in the lung was determined by the wet-to-dry weight ratio method. At control LAP levels, no significant difference in lung fluid accumulation could be shown between animals with control and elevated SVP levels. When LAP was elevated above control a significantly greater amount of pulmonary fluid accumulated in animals with elevated SVP levels compared with those with control SVP levels. We conclude that significant excess pulmonary edema formation will occur when SVP is elevated at pulmonary microvascular pressures not normally associated with rapid fluid accumulation.

[Q]: Abstract: Early mobilisation after arthroplasty of the knee sometimes results in wound breakdown. The two commonly used incisions, the anterior midline and the medial parapatellar incisions, were compared in order to determine which had the best potential for wound healing. Study of the cleavage lines around the knee demonstrated that the medial parapatellar incision lies parallel to the lines, whilst the anterior midline incision lies perpendicular to them. In addition, the medial parapatellar wound was found to be subjected to significantly less tension during flexion; after arthroplasty it can be expected to heal faster and to be less liable to disruption during early mobilisation.

[Q]: Abstract: The influence of various medium supplements on Sertoli cell (Sc) monolayer permeability to [3H]inulin and polarized secretion of transferrin (Trf) and androgen-binding protein (ABP) was investigated in a two-compartment culture chamber. Sc from 14- and 18-day-old rats were maintained for 13 days in one of the following media: Modified Eagle's Medium-Ham's F-12 (DFM), DFM plus insulin, epidermal growth factor, progesterone, hydrocortisone, and vitamins A and E (6F), 6F plus testosterone (7F), 7F plus FSH (8F), 6F plus 2% fetal bovine serum (6F2S), 6F plus 5% fetal bovine serum (6F5S). The monolayer permeability to [3H]inulin decreased rapidly during the initial 3-5 days of culture for the Sc isolated from 18- and 14-day old animals, then remained stable in all media except DFM. Morphological examination revealed the presence of tight junctions between neighbouring Sc in both age groups, indicating their de novo formation. Secretion of Trf was lowest in DFM and steadily declined. In all other media, Trf secretion peaked on day 5 and remained relatively constant after day 7. Medium 7F only slightly and inconsistently increased the secretion, whereas 8F was always highly stimulatory compared to 6F. Supplementation of 6F with serum resulted in the greatest Trf secretion. In the case of ABP, three different secretion patterns were noted depending on the medium composition; secretion was greatest in the presence of 5% fetal bovine serum. The medium supplements also differentially affected the polarity of Trf and ABP secretion. The ratio of Trf secreted to the outer and inner compartments (OC/IC) was approximately 2.0 in DFM and was not influenced by supplements in 6F, 7F, and 8F. However, in serum-containing media, the OC/IC ratio gradually increased with time to about 5.0 on day 13. The average OC/IC ratio of ABP was 1.7 in DFM and, in contrast to Trf, declined to 0.7 in other serum-free media. Serum supplementation reversed and increased the ABP ratio to about 6.0 on day 13. These data indicate that Sc grown on permeable supports form confluent monolayers that limit the diffusion of macromolecules, most likely due to the formation of tight junctions. The monolayer permeability as well as the total and polarized secretion of Trf and ABP are differentially regulated by hormones and serum factors.
