Separation of bronchoconstriction from increased ventilatory drive in a nonhuman primate model of chronic allergic asthma.

The relationship between allergen-induced ventilatory drive and bronchoconstriction was investigated in dust mite-sensitive cynomolgus macaques periodically exposed to low doses of aerosolized antigen for up to 5.5 yr. Initially, the animals responded to aerosolized dust mite allergen at a concentration of 350 arbitrary units (AU)/ml with simultaneous increases in lung resistance (RL) and respiratory rate (RR).

Comparative healing of surgical incisions created by a standard "bovie," the Utah Medical Epitome Electrode, and a Bard-Parker cold scalpel blade in a porcine model: a pilot study.

A comparative study of skin incision healing using a standard "bovie" and a new design electroscalpel, Utah Medical Products Epitome Electrode (Midvale, UT), was conducted in a porcine model. Wounds were evaluated objectively at 14 and 28 days after surgery using wound bursting strength measurements and histologic wound scoring. Each electrosurgical device was compared with wound healing of cold scalpel incisions as the gold standard using the same criteria.
