Respiratory control in preatherosclerotic susceptible and resistant pigeon aortas

RF Santerre, RJ Nicolosi, SC Smith - Experimental and Molecular …, 1974 - Elsevier
Respiratory control ratios in muscular cushions from the celiac bifureation of pigeon aortas
were determined by manometric techniques. Comparisons were made between
atherosclerosis-susceptible White Carneau and atherosclerosis-resistant Show Raced
pigeons in day-old squabs and 3–6 mo-old birds. In White Carneau squabs, respiratory
control ratios are high but by 3–6 mo have dropped to relatively low levels. In contrast to this,
in the Show Racer respiratory control ratios are low initially and increase with maturation …
