    Notes: Abstract To investigate whether pulsatile perfusion affects postoperative edema, we examined weight, total body water (TBW), and extracellular fluid (ECF) following cardiopulmonary bypass (CPB) in dogs using three different perfusion systems. Fourteen dogs were divided into three groups differing only in the perfusion system used: Sarns nonpulsatile and pulsatile roller pumps and a University of Texas pulsatile pump. Weight, TBW, and ECF were measured preoperatively and on postoperative days (POD) 1, 3, and 7. No significant differences were seen in body weight, TBW, or ECF between groups. Body TBW (percent of body weight) rose significantly (P=0.005) to 72% on POD 3 and 7. ECF (percent of body weight) rose to 58% by POD 7 (P=0.008). These three perfusion systems produced no differences in the pattern of postoperative body fluid distribution after CPB, suggesting that there is no advantage to pulsatile perfusion for the purpose of decreasing postoperative edema.

    Effects of power-line construction on wetland vegetation in Massachusetts, USA (1989)
    Springer

    Notes: Abstract Utility rights-of-way corridors through wetland areas generate long-term impacts from construction activities to these valuable ecosystems. Changes to and recovery of the vegetation communities of a cattail marsh, wooded swamp, and shrub/bog wetland were documented through measurements made each growing season for two years prior, five years following, and again on the tenth year after construction of a 345-kV transmission line. While both the cattail marsh and wooded swamp recovered within a few years, measures of plant community composition in the shrub/bog wetland were still lower, compared to controls, after ten years. Long-term investigations such as the one reported here help decrease uncertainty and provide valuable information for future decision making regarding construction of power utility lines through valuable and dwindling wetland resources.
