Aerosolized hyaluronan (HA) has been previously shown to prevent cigarette smoke-induced airspace enlargement and elastic fiber injury in mice when given concurrently with smoke. In the present study, a more stringent test of the therapeutic potential of HA was performed by delaying treatment with this agent for 1 month. After treatment with cigarette smoke(More)
This study was designed to determine if aerosolized hyaluronan (HA) could prevent airspace enlargement and elastic fiber injury in a mouse model of cigarette smoke-induced pulmonary emphysema. Compared to untreated/smoked controls, HA-treated animals showed statistically significant reductions in mean linear intercept (54 versus 65 microm; P < .001) and(More)
Three (intact) Angus males and females that were half-sibs and born within 21 d of each other were selected for this study. Each animal was bled periodically from birth to slaughter (18 mo) to determine the qualitative composition of plasma lipoproteins and apolipoproteins during its growth and development. Major components observed were: 1) very(More)
